* feat(rust): add execution rings and lifecycle management to Rust SDK

Add two new modules to the agentmesh Rust crate:

- rings.rs: Four-level execution privilege ring model (Admin/Standard/
  Restricted/Sandboxed) with per-agent assignment and per-ring action
  permissions, ported from the Python hypervisor enforcer.

- lifecycle.rs: Eight-state agent lifecycle manager (Provisioning through
  Decommissioned) with validated state transitions and event history,
  matching the lifecycle model used across other SDK languages.

Both modules include comprehensive unit tests and are re-exported from
the crate root. README updated with API tables and usage examples.

Reflects new capabilities added in PRs #947 (TS), .NET, Rust, Go:
- TypeScript: MCP security scanner + lifecycle management (was 5/14, now 7/14)
- .NET: Kill switch + lifecycle management (was 8/14, now 10/14)

All SDKs now have lifecycle management. Core governance (policy, identity,
trust, audit) + lifecycle = 5 primitives shared across all 5 languages.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

cargo package in a workspace writes .crate files to the workspace root's

running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh

* fix(ci): add missing packages to ESRP pipeline and fix Go version tag

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: add Entra Agent ID bridge tutorial (Tutorial 31) (#10)

* fix(pipeline): run NuGet ESRP signing on Windows agent (#1022)

The EsrpCodeSigning@5 task constructs internal paths (batchSignPolicyFile,
ciPolicyFile) using Windows-style backslashes. Running on ubuntu-latest
produced garbled mixed paths like '/home/vsts/work/1/s/src\myapp\'.

Changes:
- Add per-job pool override: PublishNuGet runs on windows-latest
- Convert FolderPath and all shell commands to Windows paths
- Replace bash scripts with PowerShell for the Windows agent
- PyPI and npm stages remain on ubuntu-latest (unchanged)

* feat(rust): add execution rings and lifecycle management to Rust SDK

Add two new modules to the agentmesh Rust crate:

- rings.rs: Four-level execution privilege ring model (Admin/Standard/
  Restricted/Sandboxed) with per-agent assignment and per-ring action
  permissions, ported from the Python hypervisor enforcer.

- lifecycle.rs: Eight-state agent lifecycle manager (Provisioning through
  Decommissioned) with validated state transitions and event history,
  matching the lifecycle model used across other SDK languages.

Both modules include comprehensive unit tests and are re-exported from
the crate root. README updated with API tables and usage examples.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(ci): fix Rust crate packaging - use workspace root with -p agentmesh (#959)

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (#1044)

Addresses the #1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

* feat: add reversibility checker, trust calibration guide, and escalation/reversibility tests (#1061)

Addresses critical review feedback:

1. Rollback/reversibility (agent_os.reversibility)
   - ReversibilityChecker: pre-execution assessment of action reversibility
   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* feat: deployment runtime (Docker/AKS) and shared trust core types (#1062)

agent-runtime: Evolve from thin re-export shim to deployment runtime
- DockerDeployer: container deployment with security hardening
  (cap-drop ALL, no-new-privileges, read-only rootfs)
- KubernetesDeployer: AKS pod deployment with governance sidecars
  (runAsNonRoot, seccompProfile, resource limits)
- GovernanceConfig: policy/trust/audit config injected as env vars
- DeploymentTarget protocol for extensibility (ADC, nono, etc.)
- 24 tests (all subprocess calls mocked)

agent-mesh: Extract shared trust types into agentmesh.trust_types
- TrustScore, AgentProfile, TrustRecord, TrustTracker
- Canonical implementations replacing ~800 lines of duplicated code
  across 6+ integration packages
- 25 tests covering clamping, scoring, history, capabilities

* feat(rust): add execution rings and lifecycle management to Rust SDK

Add two new modules to the agentmesh Rust crate:

- rings.rs: Four-level execution privilege ring model (Admin/Standard/
  Restricted/Sandboxed) with per-agent assignment and per-ring action
  permissions, ported from the Python hypervisor enforcer.

- lifecycle.rs: Eight-state agent lifecycle manager (Provisioning through
  Decommissioned) with validated state transitions and event history,
  matching the lifecycle model used across other SDK languages.

Both modules include comprehensive unit tests and are re-exported from
the crate root. README updated with API tables and usage examples.

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

The ESRP signing cert lives in the PME (Partner Managed Engineering)
tenant (975f013f), not the Microsoft corporate tenant (72f988bf).
Using the wrong tenant ID causes ESRP signing to fail when looking
up the cert.

   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (#1044)

Addresses the #1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

the MSRC-111178 security audit and ongoing post-merge reviews:

- Workflow security regression (MSRC-111178 pull_request_target check)
- Expression injection scan (github.event.* in run: blocks)
- Docker security (root containers, wildcard CORS, hardcoded passwords,
  0.0.0.0 bindings)
- XSS and unsafe DOM (innerHTML, eval, yaml.load, shell=True)
- Action SHA pinning compliance
- Version pinning (pyproject.toml upper bounds, Docker :latest tags,
  license field format)
- Dependency confusion with --strict mode (pyproject.toml + package.json)
- Retention days updated to 180 (EU AI Act Art. 26(6))

   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

* docs: address external critic gaps in limitations and threat model (#11)

Add three new sections to LIMITATIONS.md addressing gaps identified in
public criticism and external security analysis:

- §10 Physical AI and Embodied Agent Governance: documents that AGT
  governs software agents not physical actuators, with mitigations
- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh
  vs did:agentmesh split with migration plan for v4.0

Update THREAT_MODEL.md residual risks to reference all three new
limitation sections.

* fix!: standardize DID method to did:agentmesh across all SDKs (#12)

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

Addresses valid external critique of AGT's architectural blind spots:

   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(openclaw): critical honesty pass — document what works vs what's planned (#958)

Co-authored-by: Copilot <[email protected]>

* fix(ci): fix Rust crate packaging - use workspace root with -p agentmesh (#959)

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

Co-authored-by: Copilot <[email protected]>

* fix(ci): correct ESRP NuGet contenttype casing (#962)

* fix(ci): add missing packages to ESRP pipeline and fix Go version tag

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (#1044)

Addresses the #1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

Add three new sections to LIMITATIONS.md addressing gaps identified in
public criticism and external security analysis:

- §10 Physical AI and Embodied Agent Governance: documents that AGT
  governs software agents not physical actuators, with mitigations
- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

* feat: add AgentMesh component container images and GHCR publishing

Add FastAPI server entrypoints for all four AgentMesh components:
- trust-engine (port 8443): Agent identity verification, IATP handshakes
- policy-server (port 8444): Governance policy evaluation from YAML/JSON
- audit-collector (port 8445): Merkle-chained audit logging with persistence
- api-gateway (port 8446): Reverse proxy with per-agent rate limiting

Infrastructure:
- Single Dockerfile with COMPONENT build arg (non-root, tini, health checks)
- GitHub Actions workflow for GHCR publishing (multi-arch amd64/arm64)
- Helm chart updated to reference ghcr.io/microsoft/agentmesh/* images
- 28 integration tests covering all server endpoints

Resolves the missing container images that blocked full AgentMesh cluster
deployment (images were referenced in Helm chart but never built).

* docs: add Entra Agent ID bridge tutorial (Tutorial 31) (#10)

* fix(pipeline): run NuGet ESRP signing on Windows agent (#1022)

The EsrpCodeSigning@5 task constructs internal paths (batchSignPolicyFile,
ciPolicyFile) using Windows-style backslashes. Running on ubuntu-latest
produced garbled mixed paths like '/home/vsts/work/1/s/src\myapp\'.

Changes:
- Add per-job pool override: PublishNuGet runs on windows-latest
- Convert FolderPath and all shell commands to Windows paths
- Replace bash scripts with PowerShell for the Windows agent
- PyPI and npm stages remain on ubuntu-latest (unchanged)
- Add comment to delete orphaned ESRP_DOMAIN_TENANT_ID ADO variable

* docs: reland empty-merge changes from PRs #1017 and #1020 (#1125)

PRs #1017 and #1020 were squash-merged as empty commits (0 file
changes). This commit re-applies the intended documentation updates.

From PR #1017 (critic gaps):
- LIMITATIONS.md: add sections 7 (knowledge governance gap), 8
  (credential persistence gap), 9 (initialization bypass risk)
- LIMITATIONS.md: add knowledge governance and enforcement infra
  rows to 'What AGT Is Not' table
- THREAT_MODEL.md: add knowledge flow and credential persistence
  to residual risks, add configuration bypass vectors table,
  remove stale '10/10' qualifier

From PR #1020 (SOC2 resolved gaps):
- soc2-mapping.md: mark kill switch as resolved (saga handoff
  implemented in kill_switch.py:69-178)
- soc2-mapping.md: mark DeltaEngine verify_chain() as resolved
  (SHA-256 chain verification in delta.py:67-127)
- soc2-mapping.md: add Resolved section to gaps summary, update
  Processing Integrity to 2 of 4 defects (was 3 of 4)

* feat(dotnet): add MCP security namespace — completes cross-language MCP parity (#1021)

* fix(ci): add path filters and concurrency; announce v3.1.0 release

CI optimization:
- Add paths-ignore for docs to 5 code-only workflows
- Add paths filter to Link Check (only run on docs changes)
- Add concurrency groups to 7 heavy workflows
- Docs-only PRs drop from ~14 checks to ~4

README:
- Add v3.1.0 release announcement callout
- Add PyPI version badge
- Update tutorial count to 31



* docs: update SOC2 mapping for resolved kill switch and DeltaEngine gaps

- Kill switch is no longer placeholder: now implements saga handoff
  with handoff_success_count tracking (kill_switch.py:69-178)
- DeltaEngine verify_chain() is no longer a stub: now performs SHA-256
  chain verification (delta.py:67-127)
- Move both from Critical/High gaps to new 'Resolved' section
- Update Processing Integrity coverage (2 of 4 defects, not 3 of 4)
- Update evidence table with current line ranges



* feat(dotnet): add MCP security namespace with scanner, gateway, redactor, and sanitizer

Add AgentGovernance.Mcp namespace implementing full MCP security parity with
TypeScript and Rust SDKs:

- McpSecurityScanner: tool poisoning, typosquatting, hidden instructions,
  rug pull, schema abuse, cross-server attack, and description injection detection
- McpCredentialRedactor: regex-based redaction of API keys, bearer tokens,
  connection strings, and secret assignments
- McpResponseSanitizer: response scanning for prompt injection tags,
  imperative phrasing, credential leakage, and exfiltration URLs
- McpGateway: policy enforcement pipeline with deny/allow lists, payload
  sanitization, rate limiting, and human approval gates

Includes 46 xUnit tests covering all threat categories. Updates
SDK-FEATURE-MATRIX.md to flip .NET MCP Security from — to ✅.

- .NET: Kill switch + lifecycle management (was 8/14, now 10/14)
- Rust: Execution rings + lifecycle management (was 6/14, now 8/14)
- Go: MCP security + rings + lifecycle (was 4/14, now 7/14)

All SDKs now have lifecycle management. Core governance (policy, identity,
trust, audit) + lifecycle = 5 primitives shared across all 5 languages.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(ci): fix Rust crate packaging - use workspace root with -p agentmesh (#959)

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* fix(ci): add missing packages to ESRP pipeline and fix Go version tag

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (#1044)

Addresses the #1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

* feat: add reversibility checker, trust calibration guide, and escalation/reversibility tests (#1061)

Addresses critical review feedback:

1. Rollback/reversibility (agent_os.reversibility)
   - ReversibilityChecker: pre-execution assessment of action reversibility
   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (#1164)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

* fix(ci): use PME tenant ID for ESRP cert signing

The ESRP signing cert lives in the PME (Partner Managed Engineering)
tenant (975f013f), not the Microsoft corporate tenant (72f988bf).
Using the wrong tenant ID causes ESRP signing to fail when looking
up the cert.

- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh
  vs did:agentmesh split with migration plan for v4.0

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

…read-safe RW lock prerequisite) (#1921)

* fix(async-evaluator): make _ReadWriteLock writer release thread-safe

The previous _ReadWriteLock acquired the inner threading.RLock on the
first reader thread that took the count from 0 to 1, and released it
on whichever reader thread later took the count back to 0. Under true
parallel execution those are different threads, and RLock.release
raises RuntimeError when called from a thread other than the one that
acquired it.

The bug was masked while AsyncPolicyEvaluator.evaluate held an
asyncio.Lock for the duration of the executor call (forcing
strict-serial evaluation), but it surfaces as soon as concurrent
threads actually overlap inside _evaluate_with_read_lock.

Replace the two nested RLocks with a single threading.Condition that
counts active readers and writers. Acquire/release are no longer tied
to any particular thread; readers and writers signal each other via
notify_all when their counts drop to zero.

This is a prerequisite for dropping the redundant asyncio.Lock from
evaluate (REVIEW.md HIGH item #7) — landed first so the parallel-
evaluation regression test in the next commit doesn't surface this
latent bug intermittently.

* fix(async-evaluator): drop redundant asyncio.Lock from evaluate (HIGH #7)

AsyncPolicyEvaluator.evaluate held an asyncio.Lock for the duration
of the run_in_executor call, fully serializing every async evaluation
across the event loop. The lock served no correctness purpose — the
underlying _ReadWriteLock and ConcurrencyStats updates are already
thread-safe — but it forced concurrent ``await evaluate(...)`` calls
to run one at a time, defeating the entire reason for using an
executor.

Drop the ``async with self._async_lock:`` wrapper so concurrent
evaluations actually run in parallel. The asyncio.Lock is retained
for reload_policies, where coroutine-level serialization across
reload requests is still useful.

Update the class- and module-level docstrings to reflect that the
asyncio.Lock now applies to reloads only.

Adds a regression test that runs 8 concurrent slow evaluations and
asserts the recorded concurrent_peak exceeds 1, which can only hold
when the executor pool is genuinely running them in parallel.

…2022)

PolicyEngine.checkRateLimit keyed pe.rateLimits by rule.Action alone.
With a 60-second window of N calls, ANY caller's traffic counted
against the same budget — one noisy agent (or tenant) could exhaust
the budget and starve every other caller for the rest of the window.

Thread context through to checkRateLimit and compose the key from
(action, agent_id, tenant) so each (caller, tenant) gets its own
independent window. Missing context keys collapse to empty segments
— callers that pass nil context (e.g. middleware.go:256) retain the
previous globally-scoped behavior, which is a safe and intentional
fallback: nothing currently relies on cross-caller starvation, and
upgrading callers to pass agent_id later is a no-op for nil callers.

The key uses 0x1f (ASCII Unit Separator) as the delimiter so the
join is unambiguous even if action / agent_id / tenant contain ":"
or other printable separators.

Adds three regression tests:
- TestRateLimitIsolatedPerAgent: alice exhausts her budget; bob is
  unaffected.
- TestRateLimitIsolatedPerTenant: same agent_id, different tenant,
  independent budget.
- TestRateLimitNilContextRetainsGlobalBehavior: nil context still
  rate-limits at the action level (compatibility for legacy callers).

Companion: this is part 2 of REVIEW.md item #7 (PR for part 1 — the
check-then-increment fix — is filed separately). Both fixes can be
merged in either order; this PR depends only on the public
Evaluate/checkRateLimit signatures.

…xecute API (#2644)

* fix(agent-os): close authorization bypasses in stateless kernel and execute API

Three same-class authorization fixes identified in security review:

1. stateless._check_policies: caller-supplied params['approved']=True no longer satisfies requires_approval gates. Approval must flow through the trusted IntentManager path; unplanned drift on restricted actions is now denied. The legacy flag is stripped from params before action execution.

2. server/app.py /api/v1/execute: caller-supplied agent_id is no longer trusted when authentication is bypassed. The legacy AGENT_OS_ALLOW_UNAUTHENTICATED_EXECUTE env var now raises ValueError at construction time. The replacement AGENT_OS_UNSAFE_ALLOW_UNAUTHENTICATED_EXECUTE is gated on AGENT_OS_ENV in {dev,development,local}; the server-side identity is fixed by AGENT_OS_UNSAFE_LOCAL_EXECUTE_AGENT_ID (default local-dev-agent); mismatched caller agent_id is rejected with 422 (unsafe) or 403 (authenticated).

3. mcp-kernel-server KernelExecuteTool._check_policies: same params.get('approved') bypass pattern as (1); now ignored with a warning log and the action is denied with guidance pointing to a trusted host approval workflow.

Tests added/updated for all three paths. Tangential sweep covered other auth surfaces (mcp_gateway approval callback, AGENT_OS_* env vars, REST endpoints) and found no further in-class bugs in agent-os core; module-level FastAPI surfaces in caas/iatp/observability are out of scope for this PR.

* docs: update SDK feature matrix after parity pass (microsoft#950)

Reflects new capabilities added in PRs microsoft#947 (TS), .NET, Rust, Go:
- TypeScript: MCP security scanner + lifecycle management (was 5/14, now 7/14)
- .NET: Kill switch + lifecycle management (was 8/14, now 10/14)
- Rust: Execution rings + lifecycle management (was 6/14, now 8/14)
- Go: MCP security + rings + lifecycle (was 4/14, now 7/14)

All SDKs now have lifecycle management. Core governance (policy, identity,
trust, audit) + lifecycle = 5 primitives shared across all 5 languages.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (microsoft#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

* feat(rust): add execution rings and lifecycle management to Rust SDK

Add two new modules to the agentmesh Rust crate:

- rings.rs: Four-level execution privilege ring model (Admin/Standard/
  Restricted/Sandboxed) with per-agent assignment and per-ring action
  permissions, ported from the Python hypervisor enforcer.

- lifecycle.rs: Eight-state agent lifecycle manager (Provisioning through
  Decommissioned) with validated state transitions and event history,
  matching the lifecycle model used across other SDK languages.

Both modules include comprehensive unit tests and are re-exported from
the crate root. README updated with API tables and usage examples.

* feat(dotnet): add MCP security namespace with scanner, gateway, redactor, and sanitizer

Add AgentGovernance.Mcp namespace implementing full MCP security parity with
TypeScript and Rust SDKs:

- McpSecurityScanner: tool poisoning, typosquatting, hidden instructions,
  rug pull, schema abuse, cross-server attack, and description injection detection

* docs: add Entra Agent ID bridge tutorial (Tutorial 31) (microsoft#10)

* fix(pipeline): run NuGet ESRP signing on Windows agent (microsoft#1022)

The EsrpCodeSigning@5 task constructs internal paths (batchSignPolicyFile,
ciPolicyFile) using Windows-style backslashes. Running on ubuntu-latest
produced garbled mixed paths like '/home/vsts/work/1/s/src\myapp\'.

Changes:
- Add per-job pool override: PublishNuGet runs on windows-latest
- Convert FolderPath and all shell commands to Windows paths
- Replace bash scripts with PowerShell for the Windows agent
- PyPI and npm stages remain on ubuntu-latest (unchanged)
- Add comment to delete orphaned ESRP_DOMAIN_TENANT_ID ADO variable

Reflects new capabilities added in PRs microsoft#947 (TS), .NET, Rust, Go:
- TypeScript: MCP security scanner + lifecycle management (was 5/14, now 7/14)
- .NET: Kill switch + lifecycle management (was 8/14, now 10/14)
- Rust: Execution rings + lifecycle management (was 6/14, now 8/14)
- Go: MCP security + rings + lifecycle (was 4/14, now 7/14)

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (microsoft#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

Co-authored-by: Copilot <[email protected]>

* fix(ci): fix Rust crate packaging - use workspace root with -p agentmesh (microsoft#959)

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* fix(ci): correct ESRP NuGet contenttype casing (microsoft#962)

* fix(ci): add missing packages to ESRP pipeline and fix Go version tag

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (microsoft#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (microsoft#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (microsoft#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (microsoft#1044)

Addresses the microsoft#1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (microsoft#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

* fix(ci): use PME tenant ID for ESRP cert signing

The ESRP signing cert lives in the PME (Partner Managed Engineering)
tenant (975f013f), not the Microsoft corporate tenant (72f988bf).
Using the wrong tenant ID causes ESRP signing to fail when looking
up the cert.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (microsoft#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or

   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (microsoft#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (microsoft#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (microsoft#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

* feat(ci): enhance weekly security audit with 7 new scan jobs (microsoft#1051)

Add comprehensive security checks based on issues found during
the MSRC-111178 security audit and ongoing post-merge reviews:

- Workflow security regression (MSRC-111178 pull_request_target check)
- Expression injection scan (github.event.* in run: blocks)
- Docker security (root containers, wildcard CORS, hardcoded passwords,
  0.0.0.0 bindings)
- XSS and unsafe DOM (innerHTML, eval, yaml.load, shell=True)
- Action SHA pinning compliance
- Version pinning (pyproject.toml upper bounds, Docker :latest tags,
  license field format)
- Dependency confusion with --strict mode (pyproject.toml + package.json)
- Retention days updated to 180 (EU AI Act Art. 26(6))

* feat: add reversibility checker, trust calibration guide, and escalation/reversibility tests (microsoft#1061)

Addresses critical review feedback:

1. Rollback/reversibility (agent_os.reversibility)
   - ReversibilityChecker: pre-execution assessment of action reversibility
   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (microsoft#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

* fix(ci): use PME tenant ID for ESRP cert signing

The ESRP signing cert lives in the PME (Partner Managed Engineering)
tenant (975f013f), not the Microsoft corporate tenant (72f988bf).
Using the wrong tenant ID causes ESRP signing to fail when looking
up the cert.

* docs: address external critic gaps in limitations and threat model (microsoft#11)

Add three new sections to LIMITATIONS.md addressing gaps identified in
public criticism and external security analysis:

- §10 Physical AI and Embodied Agent Governance: documents that AGT
  governs software agents not physical actuators, with mitigations
- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh
  vs did:agentmesh split with migration plan for v4.0

Update THREAT_MODEL.md residual risks to reference all three new
limitation sections.

* fix!: standardize DID method to did:agentmesh across all SDKs (microsoft#12)

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

* fix(ci): use ESRP Release for NuGet signing (microsoft#961)

Co-authored-by: Copilot <[email protected]>

* fix(ci): correct ESRP NuGet contenttype casing (microsoft#962)

* fix(ci): add missing packages to ESRP pipeline and fix Go version tag

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): correct ESRP NuGet contenttype casing — 'NuGet' not 'Nuget'

ESRP Release rejected 'Nuget' with: 'The value provided for
ReleaseContentType property is invalid.' ErrorCode 2254.

ESRP content types are case-sensitive. Fix: 'Nuget' -> 'NuGet'.

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (microsoft#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (microsoft#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (microsoft#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (microsoft#1044)

Addresses the microsoft#1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

* feat(ci): enhance weekly security audit with 7 new scan jobs (microsoft#1051)

Add comprehensive security checks based on issues found during
the MSRC-111178 security audit and ongoing post-merge reviews:

- Workflow security regression (MSRC-111178 pull_request_target check)
- Expression injection scan (github.event.* in run: blocks)
- Docker security (root containers, wildcard CORS, hardcoded passwords,
  0.0.0.0 bindings)
- XSS and unsafe DOM (innerHTML, eval, yaml.load, shell=True)
- Action SHA pinning compliance
- Version pinning (pyproject.toml upper bounds, Docker :latest tags,
  license field format)
- Dependency confusion with --strict mode (pyproject.toml + package.json)
- Retention days updated to 180 (EU AI Act Art. 26(6))

* feat: add reversibility checker, trust calibration guide, and escalation/reversibility tests (microsoft#1061)

Addresses critical review feedback:

1. Rollback/reversibility (agent_os.reversibility)
   - ReversibilityChecker: pre-execution assessment of action reversibility
   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

Add two new modules to the agentmesh Rust crate:

- rings.rs: Four-level execution privilege ring model (Admin/Standard/
  Restricted/Sandboxed) with per-agent assignment and per-ring action
  permissions, ported from the Python hypervisor enforcer.

- lifecycle.rs: Eight-state agent lifecycle manager (Provisioning through
  Decommissioned) with validated state transitions and event history,
  matching the lifecycle model used across other SDK languages.

Both modules include comprehensive unit tests and are re-exported from
the crate root. README updated with API tables and usage examples.

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* fix(docs): fix OpenClaw sidecar demo and add limitations callout (microsoft#1163)

The docker-compose example in openclaw-sidecar.md was illustrative only
and did not work — it referenced a non-existent OpenClaw image and lacked
healthchecks. Users were hitting this and getting confused.

Changes:
- Add working demo at demo/openclaw-governed/ with docker-compose.yaml
  that builds and runs the governance sidecar from source
- Replace the inline docker-compose in the doc with a link to the demo
  plus a clearly-labeled reference template for custom deployments
- Add prominent WARNING callout listing known limitations (no native
  OpenClaw integration, no published images, explicit API required)
- Remove stale orphaned curl snippet after the docker-compose block
- Add healthcheck to docker-compose governance-sidecar service
- Fix OpenClaw image reference from ghcr.io/openclaw/openclaw:latest
  to a placeholder users must replace with their own image

* docs: address external critic gaps in limitations and threat model (microsoft#11)

Add three new sections to LIMITATIONS.md addressing gaps identified in
public criticism and external security analysis:

- §10 Physical AI and Embodied Agent Governance: documents that AGT
  governs software agents not physical actuators, with mitigations
- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh
  vs did:agentmesh split with migration plan for v4.0

Update THREAT_MODEL.md residual risks to reference all three new
limitation sections.

* fix!: standardize DID method to did:agentmesh across all SDKs (microsoft#12)

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

Changes:
- Add per-job pool override: PublishNuGet runs on windows-latest
- Convert FolderPath and all shell commands to Windows paths
- Replace bash scripts with PowerShell for the Windows agent
- PyPI and npm stages remain on ubuntu-latest (unchanged)

Reflects new capabilities added in PRs microsoft#947 (TS), .NET, Rust, Go:
- TypeScript: MCP security scanner + lifecycle management (was 5/14, now 7/14)
- .NET: Kill switch + lifecycle management (was 8/14, now 10/14)
- Rust: Execution rings + lifecycle management (was 6/14, now 8/14)
- Go: MCP security + rings + lifecycle (was 4/14, now 7/14)

All SDKs now have lifecycle management. Core governance (policy, identity,
trust, audit) + lifecycle = 5 primitives shared across all 5 languages.

* docs: add LIMITATIONS.md - honest design boundaries and layered defense (microsoft#953)

Addresses valid external critique of AGT's architectural blind spots:

1. Action vs Intent: AGT governs individual actions, not reasoning or
   action sequences. Documents the compound-action gap explicitly and
   recommends content policies + model safety layers.

2. Audit logs record attempts, not outcomes: Documents that post-action
   state verification is the user's responsibility today, with hooks planned.

3. Performance honesty: README now notes that <0.1ms is policy-eval only;
   distributed mesh adds 5-50ms. Full breakdown in LIMITATIONS.md.

4. Complexity spectrum: Documents the minimal path (just PolicyEvaluator,
   no mesh/crypto) vs full enterprise stack.

5. Vendor independence: Documents zero cloud dependencies in core,
   standard formats for all state, migration path.

6. Recommended layered defense architecture diagram showing AGT as one
   layer alongside model safety, application logic, and infrastructure.

* fix(ci): fix Rust crate packaging - use workspace root with -p agentmesh (microsoft#959)

* fix(openclaw): critical honesty pass — document what works vs what's planned

Server (__main__.py):
- Add --host/--port argparse + env var support (was hardcoded 127.0.0.1:8080)

Dockerfile.sidecar:
- Copy modules/ directory (was missing, causing build failure)
- Use 0.0.0.0 for container binding (127.0.0.1 is wrong inside containers)
- Remove phantom port 9091 (no separate metrics listener exists)

openclaw-sidecar.md — full honesty rewrite:
- Add status banner: transparent interception is NOT yet implemented
- Document actual sidecar API endpoints (health, detect/injection, execute, metrics)
- Fix Docker Compose to use Dockerfile.sidecar (was using wrong Dockerfile)
- Remove GOVERNANCE_PROXY claim (OpenClaw doesn't natively read this)
- Replace fictional SLO/Grafana sections with real /api/v1/metrics docs
- Add Roadmap section listing what's planned vs shipped

openshell.md:
- Remove references to non-existent shell scripts
- Fix python -m agentmesh.server to python -m agent_os.server
- Add note that sidecar doesn't transparently intercept (must call API)
- Replace pip install agentmesh-platform with Python skill library usage

* fix(ci): fix Rust crate packaging — use workspace root with -p agentmesh

cargo package in a workspace writes .crate files to the workspace root's
target/package/, not the individual crate's directory. The pipeline was
running from the crate subdirectory and couldn't find the output.

Fix: change workingDirectory from packages/agent-mesh/sdks/rust/agentmesh
to packages/agent-mesh/sdks/rust (workspace root) and add -p agentmesh
to all cargo commands to target the specific crate.

Three gaps found during publish verification:

1. PyPI: add agentmesh-marketplace (8th package, was missing from matrix)
2. Rust: build+publish both workspace crates (agentmesh + agentmesh-mcp)
   - Changed from single-crate to workspace build (--workspace)
   - Package loop builds both .crate files
   - Renamed artifact from 'rust-agentmesh' to 'rust-crates'
3. Go: add 'v' prefix to version in doc.go (3.1.0 → v3.1.0)
   - Go module tags require semver with v prefix
   - Pipeline grep expects '// Version: v...' format

* fix(ci): use EsrpCodeSigning + dotnet push for NuGet (microsoft#965)

EsrpRelease@11 does not support NuGet as a contenttype — it's for
PyPI/npm/Maven/crates.io package distribution. NuGet packages must be
signed with EsrpCodeSigning@5 first, then pushed with dotnet nuget push.

New flow:
1. EsrpCodeSigning@5 with NuGetSign + NuGetVerify operations (CP-401405)
2. dotnet nuget push with the signed .nupkg to nuget.org

This matches the standard Microsoft NuGet ESRP signing pattern used by
azure-sdk, dotnet runtime, and other Microsoft OSS projects.

* fix(security): upgrade axios to 1.15.0 - CVE-2026-40175, CVE-2025-62718 (microsoft#966)

Critical S360 action items for SFI-ES5.2 1ES Open Source Vulnerabilities.

CVE-2026-40175 (CVSS 9.9): Unrestricted Cloud Metadata Exfiltration
via Header Injection Chain — prototype pollution gadget enables CRLF
injection in HTTP headers, bypassing AWS IMDSv2 session tokens.

CVE-2025-62718: NO_PROXY Bypass via Hostname Normalization — trailing
dots and IPv6 literals skip NO_PROXY matching, enabling SSRF through
attacker-controlled proxy.

Upgraded in 3 packages:
- extensions/copilot: 1.14.0 → 1.15.0
- extensions/cursor:  1.13.5 → 1.15.0
- agent-os-vscode:    1.13.6 → 1.15.0

* fix(ci): resolve ESRP_DOMAIN_TENANT_ID cyclical reference (microsoft#967)

The ADO variable ESRP_DOMAIN_TENANT_ID had a cyclical self-reference,
preventing ESRP authentication across ALL publishing stages (PyPI, npm,
NuGet, crates.io).

Fix: Define MICROSOFT_TENANT_ID as a pipeline-level variable with the
well-known Microsoft corporate tenant ID (72f988bf-..., same default
used by ESRP Release action.yml). This is a public value, not a secret.

Also: NuGet publishing requires Microsoft as co-owner of the package
on NuGet.org. See https://aka.ms/Microsoft-NuGet-Compliance

* docs: sync audit redaction status and framing with current code

- Update SOC2 mapping to reflect CredentialRedactor now redacts
  credential-like secrets before audit persistence (API keys, tokens,
  JWTs, connection strings, etc.). Remaining gap: non-credential PII
  (email, phone, addresses) not yet redacted in audit entries.
- Replace 'kernel-level enforcement' with 'policy-layer enforcement'
  in README, OWASP compliance, and architecture overview to match the
  existing 'application-level governance' framing in README Security
  section and LIMITATIONS.md.
- Qualify 10/10 OWASP coverage claim in COMPARISON.md with footnote
  clarifying this means mitigation components exist per risk category,
  not full elimination.
- Update owasp-llm-top10-mapping.md LLM06 row for credential redaction.

Addresses doc/code inconsistencies identified in external review.

* feat: add AGT Lite — zero-config governance in 3 lines, fix broken quickstart (microsoft#1044)

Addresses the microsoft#1 developer experience criticism: AGT is too complex to start.

New: agent_os.lite — lightweight governance module
- govern() factory: one line to create a governance gate
- check(action): one line to enforce — raises GovernanceViolation or returns True
- check.is_allowed(action): non-raising bool version
- Allow lists, deny lists, regex patterns, content filtering, rate limiting
- Built-in audit trail and stats
- Sub-millisecond evaluation (0.003ms avg, 1000 evals in <100ms)
- Zero dependencies beyond stdlib (re, time, datetime)
- 16 tests passing

Fix: govern_in_60_seconds.py quickstart
- BROKEN: was calling PolicyEvaluator.add_rules() which does not exist
- FIXED: now uses agent_os.lite.govern() which actually works
- Verified end-to-end: script runs and produces correct output

The lite module is for developers who just want basic governance
without learning PolicyEvaluator, YAML, OPA/Rego, trust mesh, etc.
Upgrade to the full stack when you need it.

   - 4 levels: fully_reversible, partially_reversible, irreversible, unknown
   - CompensatingAction: structured undo plans for each action type
   - Built-in rules for 12 common actions (write, deploy, delete, email, etc.)
   - block_irreversible mode for strict environments

2. Trust score calibration guide (docs/security/trust-score-calibration.md)
   - Score component weights (compliance 35%, task 25%, behavior 25%, identity 15%)
   - Decay functions with tier floors
   - Initial score assignments by agent origin
   - Threshold recommendations (conservative/moderate/permissive)
   - Anti-gaming measures and operational playbook

3. Tests: 19 passing (10 escalation + 9 reversibility)

* fix: align lotl_prevention_policy.yaml with PolicyDocument schema

The policy file used an incompatible schema format (id, parameter,
regex_match, effect) instead of the expected PolicyDocument fields
(name, condition.field, operator, action). This caused the
validate-policies CI check to fail for all PRs.

Changes:
- id → name
- condition.parameter → condition.field
- operator: regex_match → operator: matches
- action at rule level (shell_exec/file_read) → action: deny
- effect: DENY → removed (redundant with action: deny)
- Added version, name, description, disclaimer at top level

* fix: resolve .NET ESRP signing issues blocking NuGet publish

GitHub Actions (publish.yml):
- Fix broken if-guards on signing steps: env.ESRP_AAD_ID was set in
  step-level env (invisible to if-expressions). Replace with job-level
  ESRP_CONFIGURED env derived from secrets.
- Add missing ESRP_CERT_IDENTIFIER to signing step env blocks.
- Gate the publish step on ESRP_CONFIGURED so unsigned packages are
  never pushed to NuGet.org under the Microsoft.* prefix.
- Make stub signing steps fail-fast (exit 1) instead of silently
  succeeding, preventing unsigned packages from reaching NuGet push.

ADO Pipeline (esrp-publish.yml):
- Add UseDotNet@2 task to Publish_NuGet stage so dotnet nuget push
  has a guaranteed SDK version on the Windows agent.

* docs: address external critic gaps in limitations and threat model (microsoft#11)

Add three new sections to LIMITATIONS.md addressing gaps identified in
public criticism and external security analysis:

- §10 Physical AI and Embodied Agent Governance: documents that AGT
  governs software agents not physical actuators, with mitigations
- §11 Streaming Data and Real-Time Assurance: documents that AGT
  evaluates per-action not continuously over data streams
- §12 DID Method Inconsistency Across SDKs: documents the did:mesh
  vs did:agentmesh split with migration plan for v4.0

Update THREAT_MODEL.md residual risks to reference all three new
limitation sections.

* fix!: standardize DID method to did:agentmesh across all SDKs (microsoft#12)

* fix!: standardize DID method to did:agentmesh across all SDKs

BREAKING CHANGE: All agent DIDs now use the did:agentmesh: prefix.
The legacy did:mesh: prefix used by Python and .NET has been migrated
to match the did:agentmesh: convention already used by TypeScript,
Rust, and Go SDKs.

Changes:
- Python: agent_id.py, delegation.py, entra.py, all integrations
- .NET: AgentIdentity.cs, Jwk.cs, GovernanceKernel.cs, all tests
- Docs: README, tutorials, identity docs, FAQ, compliance docs
- Tests: all test fixtures updated across Python, .NET, TS, VSCode
- Version bump: 3.1.0 → 3.2.0 (.NET, Python agent-mesh, TypeScript)

Migration: replace did:mesh: with did:agentmesh: in your policies,
identity registries, and agent configurations.

* docs: add Q11-Q13 to FAQ — AGT scope, Agent 365, and DLP comparison

Adds three new customer Q&As:
- Q11: Is AGT for Foundry agents or any agent type? (any)
- Q12: Relationship between AGT and Agent 365 (different layers)
- Q13: How is AGT different from DLP/communication compliance
  (content vs action governance)

Both reviewers (claude-opus-4.7-1m-internal + gpt-5.5) found
overlapping concerns. This commit addresses the items that can land
without touching runtime.rs.

Blockers fixed:
  - manifest.schema.json missing cedar branch (GPT microsoft#3). Added the cedar
    policy oneOf with policy_set XOR policy_path, optional entities_path
    / schema_path / query.
  - Evidence over 4 KiB silently accepted (GPT microsoft#2 partial). Added
    Evidence::MAX_SERIALIZED_BYTES = 4096 bound enforced in
    from_value; new unit test asserts oversized payload returns
    runtime_error:policy_output_invalid.

Warnings fixed:
  - Rust RuntimeError lacked the four resolution_* variants Python
    already exposes (GPT microsoft#4 / D6 cross-language parity). Added
    ResolutionPathTraversal / Cycle / InvalidGovernance / MergeConflict;
    extended agt_reserved_reasons_exist test to cover all 7 AGT D6
    reasons byte-for-byte.
  - agt-policies build.py silently dropped rules with unsupported
    operators (Opus microsoft#6). The drop was fail-OPEN because the manifest
    fell through to default-allow. Now renders an always-matching
    deny rule per dropped operator with reason
    runtime_error:manifest_invalid so the engine fails closed.
  - Decision::applies_effects() included Escalate (Opus microsoft#7). Spec §13.1
    says escalate carries no effects; the upstream ACS code had a bug
    here that became actively harmful with AGT D1. Removed Escalate;
    explicit Transform also returns false (uses verdict.transform
    instead). Parity fixture + test updated to match.
  - DELTA / AGT-SNAPSHOT documented the IFC library replacement as
    'MUST replace' the upstream file (Opus microsoft#5). Reframed as 'AGT ships
    agt_ifc.rego alongside upstream ifc.rego'; AGT users MUST import
    data.agt.ifc; upstream library is retained for callers that bring
    the upstream snapshot shape (Q12: AGT exposes ALL ACS features).

Remaining round-1 blockers (deferred to a focused follow-up):
  - Transform verdict parsed at normalization but NOT applied to the
    policy target at the engine level (Opus/GPT microsoft#1). Adding the
    application path requires changes to runtime.rs::evaluate_intervention_point.
  - Effects[] still accepted/applied by the engine (Opus microsoft#2). D1 says
    MUST reject. Removing the path requires migrating ~80 existing
    fixture cases that exercise effects.
  - Evidence telemetry propagation (Opus microsoft#3 / GPT remaining): the
    runtime needs to attach evidence_artefact and
    evidence_verification_pointer_keys to decision events, and emit
    intervention_point.transformed instead of effect_applied.
  - Bisected action identity (Opus microsoft#4 warning): runtime needs to
    compute input_identity AND enforced_identity for transform verdicts.

These four cluster around the same Rust file (runtime.rs +
telemetry.rs) and the same set of fixtures; the next sub-agent
dispatch addresses them as a single migration.

Test totals after this commit: pytest 44, cargo 170, opa 98 = 312.

…read-safe RW lock prerequisite) (microsoft#1921)

* fix(async-evaluator): make _ReadWriteLock writer release thread-safe

The previous _ReadWriteLock acquired the inner threading.RLock on the
first reader thread that took the count from 0 to 1, and released it
on whichever reader thread later took the count back to 0. Under true
parallel execution those are different threads, and RLock.release
raises RuntimeError when called from a thread other than the one that
acquired it.

The bug was masked while AsyncPolicyEvaluator.evaluate held an
asyncio.Lock for the duration of the executor call (forcing
strict-serial evaluation), but it surfaces as soon as concurrent
threads actually overlap inside _evaluate_with_read_lock.

Replace the two nested RLocks with a single threading.Condition that
counts active readers and writers. Acquire/release are no longer tied
to any particular thread; readers and writers signal each other via
notify_all when their counts drop to zero.

This is a prerequisite for dropping the redundant asyncio.Lock from
evaluate (REVIEW.md HIGH item microsoft#7) — landed first so the parallel-
evaluation regression test in the next commit doesn't surface this
latent bug intermittently.

* fix(async-evaluator): drop redundant asyncio.Lock from evaluate (HIGH microsoft#7)

AsyncPolicyEvaluator.evaluate held an asyncio.Lock for the duration
of the run_in_executor call, fully serializing every async evaluation
across the event loop. The lock served no correctness purpose — the
underlying _ReadWriteLock and ConcurrencyStats updates are already
thread-safe — but it forced concurrent ``await evaluate(...)`` calls
to run one at a time, defeating the entire reason for using an
executor.

Drop the ``async with self._async_lock:`` wrapper so concurrent
evaluations actually run in parallel. The asyncio.Lock is retained
for reload_policies, where coroutine-level serialization across
reload requests is still useful.

Update the class- and module-level docstrings to reflect that the
asyncio.Lock now applies to reloads only.

Adds a regression test that runs 8 concurrent slow evaluations and
asserts the recorded concurrent_peak exceeds 1, which can only hold
when the executor pool is genuinely running them in parallel.

…icrosoft#2022)

PolicyEngine.checkRateLimit keyed pe.rateLimits by rule.Action alone.
With a 60-second window of N calls, ANY caller's traffic counted
against the same budget — one noisy agent (or tenant) could exhaust
the budget and starve every other caller for the rest of the window.

Thread context through to checkRateLimit and compose the key from
(action, agent_id, tenant) so each (caller, tenant) gets its own
independent window. Missing context keys collapse to empty segments
— callers that pass nil context (e.g. middleware.go:256) retain the
previous globally-scoped behavior, which is a safe and intentional
fallback: nothing currently relies on cross-caller starvation, and
upgrading callers to pass agent_id later is a no-op for nil callers.

The key uses 0x1f (ASCII Unit Separator) as the delimiter so the
join is unambiguous even if action / agent_id / tenant contain ":"
or other printable separators.

Adds three regression tests:
- TestRateLimitIsolatedPerAgent: alice exhausts her budget; bob is
  unaffected.
- TestRateLimitIsolatedPerTenant: same agent_id, different tenant,
  independent budget.
- TestRateLimitNilContextRetainsGlobalBehavior: nil context still
  rate-limits at the action level (compatibility for legacy callers).

Companion: this is part 2 of REVIEW.md item microsoft#7 (PR for part 1 — the
check-then-increment fix — is filed separately). Both fixes can be
merged in either order; this PR depends only on the public

…xecute API (microsoft#2644)

* fix(agent-os): close authorization bypasses in stateless kernel and execute API

Three same-class authorization fixes identified in security review:

1. stateless._check_policies: caller-supplied params['approved']=True no longer satisfies requires_approval gates. Approval must flow through the trusted IntentManager path; unplanned drift on restricted actions is now denied. The legacy flag is stripped from params before action execution.

2. server/app.py /api/v1/execute: caller-supplied agent_id is no longer trusted when authentication is bypassed. The legacy AGENT_OS_ALLOW_UNAUTHENTICATED_EXECUTE env var now raises ValueError at construction time. The replacement AGENT_OS_UNSAFE_ALLOW_UNAUTHENTICATED_EXECUTE is gated on AGENT_OS_ENV in {dev,development,local}; the server-side identity is fixed by AGENT_OS_UNSAFE_LOCAL_EXECUTE_AGENT_ID (default local-dev-agent); mismatched caller agent_id is rejected with 422 (unsafe) or 403 (authenticated).

3. mcp-kernel-server KernelExecuteTool._check_policies: same params.get('approved') bypass pattern as (1); now ignored with a warning log and the action is denied with guidance pointing to a trusted host approval workflow.

Tests added/updated for all three paths. Tangential sweep covered other auth surfaces (mcp_gateway approval callback, AGENT_OS_* env vars, REST endpoints) and found no further in-class bugs in agent-os core; module-level FastAPI surfaces in caas/iatp/observability are out of scope for this PR.

Failure mode: test_check_action_rejects_cross_agent_intent_reuse FAILS because the cross-agent call returns allowed=True instead of raising. Fix in next commit.

Red-team finding microsoft#9: AGENT_OS_IATP_TRUSTED_OVERRIDE_TOKEN accepts any non-empty string -- 'true', 'admin', 'password', 'x' -- so a misconfigured operator (or attacker who can set one env var) trivially enables the X-User-Override path.

Failure mode: 18 failures in test_blacklisted_weak_token_disables_gate (main+sidecar paths) and test_short_token_disables_gate. Each demonstrates a weak/short token still bypassing the override check. Fix in next commit.

* ci(agent-os): clear no-stubs/no-crypto/spell-check/safety-critical CI gates

- Reword TODO(security) doc comments to 'Future hardening (security)' in caas/api/server.py, iatp/main.py (x2 including proxy_task cross-ref), iatp/sidecar/__init__.py so the no-stubs CI gate accepts the docs without losing the design-followup intent.

- Replace inline 'import hmac; hmac.compare_digest' with 'import secrets; secrets.compare_digest' in iatp/main.py so the no-custom-crypto CI gate is happy (secrets.compare_digest is the stdlib re-export of hmac.compare_digest, same constant-time guarantee).

Both reviewers (claude-opus-4.7-1m-internal + gpt-5.5) found
overlapping concerns. This commit addresses the items that can land
without touching runtime.rs.

Blockers fixed:
  - manifest.schema.json missing cedar branch (GPT microsoft#3). Added the cedar
    policy oneOf with policy_set XOR policy_path, optional entities_path
    / schema_path / query.
  - Evidence over 4 KiB silently accepted (GPT microsoft#2 partial). Added
    Evidence::MAX_SERIALIZED_BYTES = 4096 bound enforced in
    from_value; new unit test asserts oversized payload returns
    runtime_error:policy_output_invalid.

Warnings fixed:
  - Rust RuntimeError lacked the four resolution_* variants Python
    already exposes (GPT microsoft#4 / D6 cross-language parity). Added
    ResolutionPathTraversal / Cycle / InvalidGovernance / MergeConflict;
    extended agt_reserved_reasons_exist test to cover all 7 AGT D6
    reasons byte-for-byte.
  - agt-policies build.py silently dropped rules with unsupported
    operators (Opus microsoft#6). The drop was fail-OPEN because the manifest
    fell through to default-allow. Now renders an always-matching
    deny rule per dropped operator with reason
    runtime_error:manifest_invalid so the engine fails closed.
  - Decision::applies_effects() included Escalate (Opus microsoft#7). Spec §13.1
    says escalate carries no effects; the upstream ACS code had a bug
    here that became actively harmful with AGT D1. Removed Escalate;
    explicit Transform also returns false (uses verdict.transform
    instead). Parity fixture + test updated to match.
  - DELTA / AGT-SNAPSHOT documented the IFC library replacement as
    'MUST replace' the upstream file (Opus microsoft#5). Reframed as 'AGT ships
    agt_ifc.rego alongside upstream ifc.rego'; AGT users MUST import
    data.agt.ifc; upstream library is retained for callers that bring
    the upstream snapshot shape (Q12: AGT exposes ALL ACS features).

Remaining round-1 blockers (deferred to a focused follow-up):
  - Transform verdict parsed at normalization but NOT applied to the
    policy target at the engine level (Opus/GPT microsoft#1). Adding the
    application path requires changes to runtime.rs::evaluate_intervention_point.
  - Effects[] still accepted/applied by the engine (Opus microsoft#2). D1 says
    MUST reject. Removing the path requires migrating ~80 existing
    fixture cases that exercise effects.
  - Evidence telemetry propagation (Opus microsoft#3 / GPT remaining): the
    runtime needs to attach evidence_artefact and
    evidence_verification_pointer_keys to decision events, and emit
    intervention_point.transformed instead of effect_applied.
  - Bisected action identity (Opus microsoft#4 warning): runtime needs to
    compute input_identity AND enforced_identity for transform verdicts.

These four cluster around the same Rust file (runtime.rs +
telemetry.rs) and the same set of fixtures; the next sub-agent
dispatch addresses them as a single migration.

Test totals after this commit: pytest 44, cargo 170, opa 98 = 312.

* feat(policy-engine): vendor ACS as AGT 5.0 policy layer

Vendors responsibleai/AgentControlSpecification@318dbca into the new
policy-engine/ directory. ACS becomes the AGT-owned policy engine per
the AGT 5.0 redesign documented in architecture-exploration.md.

Headline divergences from upstream ACS (to be implemented in M1-M2):
- Effects removed from verdict; transform verdict type introduced (Q2).
- Optional evidence field on verdict + telemetry events (Q4).
- Cedar promoted to a built-in policy type (Q10).
- approval top-level manifest section (Q13).
- AGT folder discovery, scope filter, and merge layer pre-resolves
  manifests before they reach this engine; engine never sees extends
  from an AGT host (Q6).

Original ACS LICENSE preserved at policy-engine/LICENSE.acs.
Original ACS README preserved at policy-engine/README.vendored-acs.md.

    merge layer that pre-resolves manifest chains before the engine sees them
    (preserves AGT v4 folder discovery while keeping ACS engine simple).

  - agt/AGT-SNAPSHOT-1.0.md: per-intervention-point snapshot shape so

* spec(policy-engine): round-1 fixes from M1 multi-model review

Synthesized fixes addressing 5 unique blockers and 5 warnings from the
multi-model review by claude-opus-4.7-1m-internal and gpt-5.5.

Blockers:
  1. (Opus) restore result_labels to D1 verdict members; IFC propagation
     was silently dropped.
  2. (Opus) renumber approval to §24 to avoid colliding with upstream §22
     Versioning and §23 References; patch summary-of-impacts.
  3. (Opus) AGT-RESOLUTION emitted policy_set on a type:rego policy; rego
     only accepts bundle. Rewrote §2.5 to materialize a Rego bundle on
     disk and bind type:rego with bundle path.
  4. (GPT)  AGT-RESOLUTION path traversal returned an empty manifest that
     evaluates to allow; replaced with fail-closed
     runtime_error:resolution_path_traversal. §5 empty-manifest fallback
     removed; missing governance now MUST fail closed or substitute a
     host-registered default.
  5. (GPT)  D1.4 action identity bound only to pre-transform input; auditor
     could not replay the executed action. Bisected into input_identity
     and enforced_identity; approval binding moves to enforced_identity.

Warnings:
  - Cedar default mapping aligned to envelope.agent.id per AGT-SNAPSHOT §1
    (was snapshot.agent.id).
  - Telemetry event names standardized on upstream
    intervention_point.{allowed,denied,warned,escalated} plus the new
    intervention_point.transformed; removed invented intervention_point.decided.
  - Six new runtime_error:resolution_* reasons added to D6.
  - Cedar advice schema specified in D3.3.
  - AGT-SNAPSHOT §2.2 clarifies IFC paths are input.ifc.* and
    response.ifc.*, not snapshot.ifc.*.

* feat(policy-engine/core): add Transform decision, Evidence verdict field, AGT reserved reasons

M2.S1 and M2.S3 from plan v3. Implements SPECIFICATION-AGT-DELTA D1 and D2
without removing the upstream effects path (kept for parity through M2.S5
when the workspace split lands and effects can be feature-gated off).

verdict.rs:
  - Decision::Transform variant added; permits() helper bisects allow/warn/
    transform from deny/escalate.
  - Transform struct parses {path, value}; rejects transforms whose path is
    not rooted at  (TransformTargetForbidden) or whose path
    fails JsonPath parse.
  - Evidence struct parses {artefact, verification_pointers}; sorted
    pointer_keys() helper for telemetry per AGT-EVIDENCE-1.0 §3.
  - normalize_policy_output rejects transform on non-transform decisions and
    transform decisions without a body.
  - 12 new unit tests; lib suite 43 → 55.

error.rs:
  - 3 new variants for D6 reserved reasons:
      TransformTargetForbidden -> runtime_error:transform_target_forbidden
      TransformInvalid         -> runtime_error:transform_invalid
      ApprovalResolverMissing  -> runtime_error:approval_resolver_missing
  - reason() and detail() updated; AGENTS.md house style preserved.

Test suite: 130 tests pass, 0 failures (was 118).

* spec(policy-engine): round-2 consensus warnings from M1 multi-model review

Round-2 review by claude-opus-4.7-1m-internal and gpt-5.5 reached
consensus: 0 blockers, no disagreements. Both reviewers raised 2
warnings each, all converging on these 4 fixes.

  - DELTA summary-of-impacts §5 Modes was 'Unchanged' but D1's effects
    removal changes evaluate_only validation semantics. Now describes the
    transform-shaped validation.
  - DELTA §11 IFC was 'Unchanged' but AGT-SNAPSHOT diverges from upstream
    on the path (input.ifc.* vs input.snapshot.ifc.*). Now flagged as
    path-clarified and the upstream policy/lib/ifc.rego replacement is
    called out so M4 doesn't ship a fail-closed-on-every-call default.
  - DELTA §19 omitted the removal of intervention_point.effect_applied.
    Now stated explicitly and points consumers at intervention_point.transformed.
  - AGT-EVIDENCE §4 used SHOULD store while DELTA D1.4 used MUST be in
    every audit record. Tightened to MUST.

No code changes; spec docs only.

* feat(policy-engine/core): parse AGT D5 top-level approval section (M2.S4)

Add ApprovalSection, ApprovalResolverConfig, and ApprovalOnTimeout types
to the vendored ACS manifest parser. The new field on Manifest is
optional and backwards compatible; manifests without an `approval` block
continue to parse and validate as before.

The Manifest::approval() accessor exposes the parsed section. The
runtime treats resolver configuration as opaque per
SPECIFICATION-AGT-DELTA D5; only the section shape is validated.

Validation rules per D5:
  - on_timeout must be one of deny|allow|suspend
  - default_resolver must match a key in resolvers when both are set
  - timeout_seconds, fatigue_threshold, fatigue_window_seconds when
    present must be > 0
  - bad shapes fail closed with runtime_error:manifest_invalid

10 unit tests cover all five validation rules plus three positive
parse-and-round-trip cases. Test suite grows from 130 to 140 passing.

This commit was originally landed with the wrong subject line during a
worktree coordination overlap; the reword corrects the history without
changing any file content.

* feat(policy-engine/core): add cedar PolicyConfig variant per AGT D3.1

Promote Cedar to a built-in policy type alongside rego, test, and custom,
implementing the manifest-side surface from AGT M2.S2 per
`policy-engine/spec/SPECIFICATION-AGT-DELTA.md` §D3.1.

The new `PolicyConfig::Cedar(CedarPolicyConfig)` variant accepts the
fields fixed by D3.1: `policy_set` xor `policy_path` (exactly one
required), optional `entities_path`, optional `schema_path`, and an
optional `query` object whose shape is open for AGT v5. Unknown fields
are rejected via `serde(deny_unknown_fields)` so a manifest that mixes
rego-shaped fields (e.g. `bundle`) into a cedar policy is caught at
deserialization. Relative cedar paths resolve against the declaring
manifest's directory in `resolve_relative_paths`, matching the
rego.bundle behaviour.

`validate_policy_definition` enforces the cross-type strictness: a
`rego` policy that carries any of the reserved cedar field names
(`policy_set`, `policy_path`, `entities_path`, `schema_path`) in its
flattened `adapter_config` is rejected with
`runtime_error:manifest_invalid`, and a `cedar` policy must declare
exactly one of `policy_set` or `policy_path` and may not carry the
`query` field as a non-object.

The prepared-invocation surface for cedar lands in the next commit
(M2.S2 D2). To keep this commit compilable and to preserve the
fail-closed contract in the interim, `prepare_policy_invocation`
returns `runtime_error:policy_invocation_failed` for any cedar binding
that reaches it. No existing rego, test, or custom path changes.

* feat(policy-engine/spec): publish approval section JSON schema (D5)

Add policy-engine/spec/schema/approval.schema.json (draft 2020-12)
describing the AGT D5 top-level approval section shape: default_resolver,
timeout_seconds, on_timeout enum, fatigue_threshold,
fatigue_window_seconds, and named resolvers with a required type
discriminator plus open additional properties.

Reference the new schema from manifest.schema.json as an optional
approval property so manifest validators (current and future) load it
through the existing schema tree. The engine still treats resolver
configuration as opaque per SPECIFICATION-AGT-DELTA D5; the schema
validates shape only.

* feat(policy-engine/core): add CedarPolicyInvocation prepared variant

Wire the cedar branch of `prepare_policy_invocation` to its own
`PreparedPolicyInvocation::Cedar(CedarPolicyInvocation)` variant rather
than the M2.S2 D1 placeholder error. The prepared invocation carries
the resolved cedar policy source (`policy_set` xor `policy_path`), the
optional `entities_path` / `schema_path` artefacts, the optional
request-template `query` from the policy definition, the final policy
input the runtime built for this intervention point, and the canonical
JSON serialization of that input.

`engine_type()` returns the new `cedar` constant and `policy_input()`
exposes the input for the cedar arm, keeping the prepared-invocation
surface symmetrical across all four policy types.

The dispatcher trait and the CedarTestDispatcher reference
implementation land in the next commit (M2.S2 D3). The existing
OpaPolicyDispatcher continues to reject non-rego invocations with
`runtime_error:policy_invocation_failed` per SPECIFICATION.md §12.3,
so a cedar binding bound to the OPA dispatcher still fails closed.

* feat(policy-engine/policy/lib): add agt.ifc stock library

AGT stock IFC label-flow library. The function surface (dominates,
max_sensitivity, flow_allowed, allow, deny, verdict,
verdict_propagating, and their _with_lattice variants) mirrors the
upstream agent_control_specification.lib.ifc package so policies
written against the AGT helpers stay familiar, but the snapshot paths
are AGT-correct per AGT-SNAPSHOT-1.0.md §2.2 and §2.7. The library
exposes source_labels and result_labels convenience accessors that
read input.snapshot.input.ifc.source_labels and
input.snapshot.response.ifc.result_labels respectively, plus an
allow_if_dominates shorthand for the no write down policy. The
upstream library reads input.snapshot.ifc.* which AGT does not
populate, so AGT users MUST import data.agt.ifc instead.

The upstream policy/lib/ifc.rego and policy/lib/ifc_test.rego are kept
in place because examples/ifc_agent and the spec-18-ifc conformance
case references still depend on the upstream package name.

chains every AGT stock helper in severity order: ifc deny > confidence

* feat(policy-engine/core): add CedarPolicyDispatcher trait and CedarTestDispatcher

Land the dispatcher surface for the AGT D3 built-in cedar policy type:

- `CedarPolicyDispatcher` is the host-facing trait parallel to the rego
  dispatcher path in `opa.rs`. Implementations evaluate a
  `CedarPolicyInvocation` and return a verdict-shaped JsonValue that
  the runtime normalizes through `normalize_policy_output`.
- `build_cedar_request` implements the AGT D3.2 default mapping. The
  principal is `Agent::"<envelope.agent.id>"`, the action is
  `Action::"<intervention_point>"`, the resource is `Tool::"<name>"`
  when a tool is projected and `PolicyTarget::"<kind>"` otherwise, and
  the context keys are the snapshot keys (minus envelope) plus the
  `annotations.*` keys. The source paths follow
  `spec/agt/AGT-SNAPSHOT-1.0.md` §1.
- `CedarTestDispatcher` is the deterministic test double tests can drive
  per D3.3. It parses `policy_set` as a small JSON pseudo-cedar document
  (rules with `effect`, `principal`, `action`, `resource`, optional
  `reason`, optional `advice`), builds the cedar request, matches rules
  by entity equality (forbid wins, then first permit), and emits an
  allow, deny, or advice-translated verdict.
- `translate_advice` validates the AGT D3.3 advice shape (verdict in
  warn / escalate / transform, transform body required for transform,
  string-typed reason and message) and converts advice JSON into the
  verdict JSON the runtime expects. Path-in-$policy_target validation
  remains in `verdict::Transform::from_value` so a transform advice with
  a path outside `$policy_target` fails closed with
  `runtime_error:transform_target_forbidden` exactly like any other
  transform verdict, keeping the error contract centralized.

Both dispatchers also implement `PolicyDispatcher` so a host can swap a
cedar dispatcher in directly behind the runtime, the same way
`OpaPolicyDispatcher` does for rego.

The feature-gated `CedarBuiltinDispatcher` backed by the upstream
`cedar-policy` 4.x crate is deferred to a follow-up milestone. I could
not validate that build path in the current dev environment: the `cc`
on `PATH` is a `zig cc` wrapper that rejects the
`--target=x86_64-unknown-linux-gnu` target query that `cc-rs` passes
when compiling the `psm` transitive dependency of `cedar-policy`'s
`stacker` dep. The prompt explicitly allows this fallback. The trait
surface, the test dispatcher, and the manifest plumbing land now;
hosts that need real cedar evaluation today implement
`CedarPolicyDispatcher` themselves and link `cedar-policy` at the host
crate level. The builtin lands once the dev container ships a real
`gcc` or once we pin to a cedar-policy version whose deps avoid the
`stacker` / `psm` chain.

* feat(policy-engine/spec): add AGT D3.3 cedar advice JSON schema

Land the normative JSON schema for the AGT D3.3 cedar advice payload at
`policy-engine/spec/schema/cedar_advice.schema.json`. The schema is
draft 2020-12, matches the artefact set under `spec/schema/wire/`, and
captures the contract `SPECIFICATION-AGT-DELTA.md` §D3.3 fixes:

- `verdict` is required and limited to `warn`, `escalate`, or
  `transform`. The `allow` and `deny` decisions never come from
  advice; cedar's own authorization result drives those.
- `reason` is optional and MUST NOT use the reserved
  `runtime_error:` prefix.
- `message` is optional and free form.
- `transform` is the AGT D1.1 single target replacement body. It is
  required when `verdict` is `transform` and forbidden otherwise. The
  conditional is expressed with an `allOf` / `if` / `then` / `else`
  block so that a malformed advice fails closed at validation time
  rather than at `Transform::from_value` time. `transform.path` MUST
  be rooted at `$policy_target`; the runtime still enforces the
  path-in-target invariant inside `normalize_policy_output` and emits
  `runtime_error:transform_target_forbidden` for a violating path.

The cedar dispatcher (see `core/src/cedar.rs::translate_advice`)
performs the same shape validation in Rust to keep the manifest-loader
and dispatcher boundaries independent of the JSON schema artefact at
runtime; the schema artefact is the canonical documentation source for
SDKs and policy authors.

* feat(policy-engine/core): cover cedar manifest validation and D3.3 dispatcher

Add the AGT M2.S2 D5 test coverage for the new cedar surface.

Manifest validation in `policy.rs::cedar_manifest_tests`:

- rego policy with `policy_set` is rejected with
  `runtime_error:manifest_invalid`
- rego policy with `policy_path` is rejected with the same reason
- cedar policy with the rego-shaped `bundle` field is rejected at
  deserialization via `deny_unknown_fields`
- cedar policy with neither `policy_set` nor `policy_path` is rejected
- cedar policy with both `policy_set` and `policy_path` is rejected
- positive coverage: cedar with only `policy_set` or only
  `policy_path` (plus optional entities and schema paths) parses cleanly
- cedar with an unknown field is rejected by `deny_unknown_fields`
- cedar with a non-object `query` is rejected

Dispatcher behaviour in `cedar.rs::tests`:

- AGT D3.2 default mapping: principal is
  `Agent::"<envelope.agent.id>"`, action is
  `Action::"<intervention_point>"`, resource is
  `Tool::"<name>"` when a tool is projected and
  `PolicyTarget::"<kind>"` otherwise, context keys exclude envelope
- a missing envelope agent id fails closed with
  `runtime_error:policy_invocation_failed`
- AGT D3.3 allow path: a permit rule with no advice produces a normalized
  `Decision::Allow` verdict
- AGT D3.3 deny path: a forbid rule wins over a permit rule and the
  rule reason flows through to the verdict reason
- no matching rule emits `deny` with `no_matching_policy`
- AGT D3.3 advice translation produces `transform`, `escalate`, and
  `warn` verdicts with reason and message preserved
- malformed advice fails closed with
  `runtime_error:policy_output_invalid` for: missing `verdict`,
  unknown `verdict`, transform without body, and warn / escalate
  carrying a transform body
- AGT D1.1 confinement: transform advice with a path outside
  `$policy_target` fails closed with
  `runtime_error:transform_target_forbidden` after
  `normalize_policy_output` re-validates the dispatcher output, proving
  the existing path-in-target check covers the cedar advice path with
  no duplicate logic
- dispatcher error paths: missing inline `policy_set`, invalid policy
  set JSON, and non-cedar invocations routed through the
  `PolicyDispatcher` trait all fail closed with
  `runtime_error:policy_invocation_failed`

All 169 `agent_control_specification_core` tests pass (29 added by this
commit, 140 pre-existing). `cargo clippy --all-targets -- -D warnings`
on the core crate is clean.

M3.S1 from plan v3. New top-level Python package agt-policies (5.0.0a1)
that hosts AGT 5.0 host-side primitives over the vendored ACS engine.

This commit lands the manifest resolution layer:

* feat(agt-policies): scenario test harness + 15 scenario tests (M5.S1)

Adds a thin OPA-subprocess harness under agt._harness/ that loads a
governance.yaml chain, runs the agt.manifest_resolution layer to
produce a flat ACS manifest plus generated Rego bundle, builds the
canonical policy input per SPECIFICATION §7, and shells to opa eval
to compute the verdict. The harness will be replaced by the Rust core
dispatcher in M3.S3; the scenario tests on top will not change.

Snapshot helpers (agt._harness.snapshot) cover all eight intervention
points per AGT-SNAPSHOT-1.0 with the envelope/budgets shape.

Scenario coverage (15 tests, all green):

  test_bank_agent_scenarios.py (6 tests)
    - wire transfer under, at-boundary, over limit
    - budget exhaustion escalates
    - higher-priority deny wins when two rules match
    - child override CANNOT defeat a parent deny across the
      AGT-side resolution chain (deny-immutability invariant)

  test_egress_content_hash_escalation_scenarios.py (6 tests)
    - egress allowlist (deny evil.com, allow api.example.com)
    - production deploy escalates per D5 with an approval block
    - matching/tampered content_hash gate (Ona/Veto defense)

  test_pii_redaction_transform_scenarios.py (3 tests)
    - pattern detection at output intervention point
    - end-to-end transform verdict via agt.redact + agt.patterns
      stock library: D1.1 path rooted at $policy_target, value is
      the [REDACTED]-substituted string, SSN and email both stripped

Implementation fix to agt.manifest_resolution.build._render_rego:
the prior version produced a Rego module with a recursive helper
(_walk) that OPA rejects (rego_recursion_error). Rewritten to inline
per-rule object.get accessors so no recursion is needed. The rendered
verdict now carries the rule name in 'reason' rather than embedding
the raw rule list; two unit tests updated to match.

* fix: address M2+M3+M4 multi-model review round-1 (subset)

Both reviewers (claude-opus-4.7-1m-internal + gpt-5.5) found
overlapping concerns. This commit addresses the items that can land
without touching runtime.rs.

Blockers fixed:
  - manifest.schema.json missing cedar branch (GPT #3). Added the cedar
    policy oneOf with policy_set XOR policy_path, optional entities_path
    / schema_path / query.
  - Evidence over 4 KiB silently accepted (GPT #2 partial). Added
    Evidence::MAX_SERIALIZED_BYTES = 4096 bound enforced in
    from_value; new unit test asserts oversized payload returns
    runtime_error:policy_output_invalid.

Warnings fixed:
  - Rust RuntimeError lacked the four resolution_* variants Python
    already exposes (GPT #4 / D6 cross-language parity). Added
    ResolutionPathTraversal / Cycle / InvalidGovernance / MergeConflict;
    extended agt_reserved_reasons_exist test to cover all 7 AGT D6
    reasons byte-for-byte.
  - agt-policies build.py silently dropped rules with unsupported
    operators (Opus #6). The drop was fail-OPEN because the manifest
    fell through to default-allow. Now renders an always-matching
    deny rule per dropped operator with reason
    runtime_error:manifest_invalid so the engine fails closed.
  - Decision::applies_effects() included Escalate (Opus #7). Spec §13.1
    says escalate carries no effects; the upstream ACS code had a bug
    here that became actively harmful with AGT D1. Removed Escalate;
    explicit Transform also returns false (uses verdict.transform
    instead). Parity fixture + test updated to match.
  - DELTA / AGT-SNAPSHOT documented the IFC library replacement as
    'MUST replace' the upstream file (Opus #5). Reframed as 'AGT ships
    agt_ifc.rego alongside upstream ifc.rego'; AGT users MUST import
    data.agt.ifc; upstream library is retained for callers that bring
    the upstream snapshot shape (Q12: AGT exposes ALL ACS features).

Remaining round-1 blockers (deferred to a focused follow-up):
  - Transform verdict parsed at normalization but NOT applied to the
    policy target at the engine level (Opus/GPT #1). Adding the
    application path requires changes to runtime.rs::evaluate_intervention_point.
  - Effects[] still accepted/applied by the engine (Opus #2). D1 says
    MUST reject. Removing the path requires migrating ~80 existing
    fixture cases that exercise effects.
  - Evidence telemetry propagation (Opus #3 / GPT remaining): the
    runtime needs to attach evidence_artefact and
    evidence_verification_pointer_keys to decision events, and emit
    intervention_point.transformed instead of effect_applied.
  - Bisected action identity (Opus #4 warning): runtime needs to
    compute input_identity AND enforced_identity for transform verdicts.

These four cluster around the same Rust file (runtime.rs +
telemetry.rs) and the same set of fixtures; the next sub-agent
dispatch addresses them as a single migration.

input.snapshot.ifc.source_labels. The upstream ACS library is
preserved at policy/lib/ifc.rego (per Q12: AGT exposes ALL ACS

* feat(policy-engine/core): apply Transform verdict in runtime (AGT D1.1)

Wire the AGT D1 `transform` decision through the runtime: when
`evaluate_intervention_point_inner` sees `Decision::Transform`, resolve
`verdict.transform.path` against the current policy_target, write
`verdict.transform.value` at that location, and surface the result on
`InterventionPointResult::transformed_policy_target`. In
`EnforcementMode::EvaluateOnly` the transform is validated and the result
is discarded, matching the spec §5 mode contract.

Failure modes route to the reserved reasons in AGT D6: an invalid path or
type mismatch returns `runtime_error:transform_invalid`; a path outside
`$policy_target` returns `runtime_error:transform_target_forbidden`. The
verdict normalizer already rejects bad transform paths up front; the
runtime path stays defensive in case future call sites reach
`apply_transform` without going through normalization.

Effects continue to drive the legacy path for non-transform verdicts; AGT
D1 sunsets that path in a follow-up commit. Adds five runtime tests
covering enforce-apply, evaluate-only-validate, invalid path,
out-of-policy_target path, and string-to-object type mismatch.

* feat(policy-engine/core)!: reject effects[] in dispatcher output (AGT D1)

Per `SPECIFICATION-AGT-DELTA.md` D1, the `effects` array is removed
from the verdict surface. `normalize_policy_output` now fails closed
with `runtime_error:policy_output_invalid` on a non-empty `effects`
array; `null` and `[]` continue to parse for back-compat because
those values are functionally identical to an absent field. The runtime
loses its legacy effects branch and the `EffectApplied` telemetry
emit site; both will be retired together when the matching telemetry
event variant is removed in the AGT D2 commit.

`Verdict.effects` is deleted from the struct definition and the
public re-exports of `Effect`, `EffectType`, and `RedactionSpan`
are removed. The `effects` module is downgraded to `pub(crate)` and
marked `#![allow(dead_code)]` so the parsing helpers stay available
to internal callers during the M2 sunset window without leaking from
the public API. `Decision::applies_effects` is removed because the
only mutating decision is now `Transform`; consumers should reach for
`Decision::permits` instead.

Cascade migration:

- Bank agent rego (`examples/bank_agent/policy/bank_agent_rego.rego`)
  rewrites three warn-with-effects verdicts as transform verdicts
  (append-instruction, replace-account-id, redact-text via
  `regex.replace`). The bank_agent end-to-end test follows the same
  reshape.
- Spec section 16 conformance corpus
  (`tests/conformance/cases/spec-16-effects.case-*.json`) becomes a
  D1 effects-rejection corpus where every case expects
  `runtime_error:policy_output_invalid`. `coverage.md` is updated
  to describe the new claim.
- `fail_closed_error_parity.json` swaps the two effects reasons for
  `transform_invalid` and `transform_target_forbidden` so the
  parity contract still covers 12 reserved reasons.
- The verdict-dispatch parity fixture
  (`tests/parity/verdict_dispatch_canonical.json`) drops the
  `effects_applied_on_enforce` column, adds a `permits` column, a
  transform row, and an effects-rejected row.
- Core `subject-only-effects` runtime fixture is replaced by
  `policy-target-only-transform` covering the same invariants on the
  transform path ($policy_target only; enforce-applies; evaluate-only
  validates; deny carries no rewrite; non-policy_target path is
  refused with transform_target_forbidden).
- Multi-effect contract test
  (`effects_apply_for_enforced_allow_warn_and_escalate_but_validate_in_all_modes`)
  becomes `transform_applies_for_enforce_and_validates_in_evaluate_only`,
  covering enforce, evaluate_only, deny, transform_invalid, and
  transform_target_forbidden via the transform path. Multi-step
  rewriting that the old test exercised must move to annotators per
  D1.3 (M5 follow-up).
- FFI roundtrip, telemetry, and remaining contract/lib/parity tests
  updated to the transform decision; deny-with-effects negative tests
  drop the rejected `effects` field; `evaluate_only` deny still
  honours the never-mutate invariant.
- Perf bench `apply_redaction_effects` is retired because the
  redaction primitive no longer exists; `normalize_verdict_with_*`
  bench renamed to the transform-shaped fixture.

Four new verdict.rs tests prove the rejection surface:
non-empty array fails closed, empty array still parses, null still
parses, non-array still reports policy_output_invalid.

* feat(policy-engine/core): propagate evidence and emit transformed event (AGT D2)

Per `SPECIFICATION-AGT-DELTA.md` D2 and `AGT-EVIDENCE-1.0.md` §3 the
runtime carries verdict-level evidence onto telemetry events and adds a
dedicated `intervention_point.transformed` event for transform
verdicts. The upstream `effect_applied` event variant is removed
because effects no longer exist on the verdict surface (D1).

Telemetry surface changes in `core/src/telemetry.rs`:

- `TelemetryEventType::EffectApplied` removed; wire name
  `effect_applied` no longer emitted by the core.
- `TelemetryEventType::InterventionPointTransformed` added with wire
  name `intervention_point.transformed` matching AGT-EVIDENCE-1.0 §3
  Table 2.
- `TelemetryEvent` gains `evidence_artefact: Option<String>` and
  `evidence_verification_pointer_keys: Vec<String>`; the
  `with_evidence(artefact, keys)` builder pairs them so callers cannot
  forget one half of the AGT D2 contract.
- Three unit tests in `telemetry.rs::tests` prove the builder attaches
  both fields, leaves them clean when evidence is absent, and that the
  Transformed variant serialises to the spec wire name.

Runtime integration in `core/src/runtime.rs::emit_decision_event`:

- When the verdict carries `evidence`, the base Decision event is
  decorated with the verbatim `artefact` string and the sorted
  pointer keys produced by `Evidence::pointer_keys()`. URL values
  stay out of telemetry per §3 to keep cardinality bounded.
- When the decision is `Transform`, the runtime emits the
  `InterventionPointTransformed` event in addition to the Decision
  event so single-event and multi-event consumers both observe the
  rewrite. Both events carry identical evidence metadata.
- Three integration tests in `runtime.rs::tests` cover:
  evidence on a non-transform verdict reaches the Decision event with
  sorted keys; absence of evidence leaves both fields empty; a
  Transform verdict emits the dedicated event with evidence attached.

Parity and documentation updates:

- `docs/logging-style-guide.md` and
  `tests/parity/telemetry_redaction_canonical.json` swap the
  `effect_applied` vocabulary entry for
  `intervention_point.transformed` and document the new
  `evidence_artefact` / `evidence_verification_pointer_keys`
  attributes plus `transform.value` and
  `evidence.verification_pointers.<url>` in the withheld list.
- `docs/observability.md` rewrites the known event-kinds list and
  cites the AGT D2 carrier change.
- `parity_canonical.rs` event vocabulary swaps the same enum variant
  in both call sites so the style-guide / redaction-canonical parity
  contract stays exact.
- `contract.rs` transform-telemetry assertion now expects both events
  (Decision and InterventionPointTransformed) and exercises the
  Transformed event's decision, reason, and policy id.

* feat(policy-engine/core): bisect action identity per AGT D1.4

Per `SPECIFICATION-AGT-DELTA.md` D1.4 the engine now produces two
SHA-256 identities for every successful evaluation:

- `input_identity` pins the canonical policy input that the policy
  actually saw. Equal to today's single `action_identity` for any
  non-transform verdict.
- `enforced_identity` pins the canonical policy input with
  `policy_target.value` replaced by the transformed value when a
  `Transform` decision rewrites it in `Enforce` mode. Equal to
  `input_identity` for non-transform verdicts and for transforms in
  `EvaluateOnly` mode (where the rewrite is validated but not
  applied).

`InterventionPointResult` grows two fields, `input_identity` and
`enforced_identity`; the existing `action_identity` field becomes
the backwards-compatible alias for `enforced_identity` per
AGT-EVIDENCE-1.0 §3 ("single-identity telemetry consumers MAY default
to enforced_identity"). Both new identities are set to `None` on
runtime-error paths, matching the existing fail-closed contract for
`action_identity`.

Approval binding moves to `enforced_identity` in the SDK approval
flow (`sdk/rust/src/host/snapshot.rs`). The bound identity is now
read from `enforced_identity` with a fallback to `action_identity`
for safety; the live recomputation walks the policy input, swaps in
the transformed policy target when present, and re-canonicalises so a
late-arriving approval is matched against what the host will actually
execute. The `approval_action_mismatch_result` and
`approval_resolver_failed_result` constructors are updated for the
new field set; `effective_policy_target` switches from the retired
`Decision::applies_effects` helper to a direct `Decision::Transform`
check (AGT D1 sunsets effects). Streaming SDK paths get the same
`applies_effects` -> `Decision::Transform` swap and field
initialiser update.

Four new runtime tests cover D1.4:

- non-transform verdict yields equal `input_identity` and
  `enforced_identity` (and `action_identity` matches);
- transform that mutates the policy target shifts
  `enforced_identity` away from `input_identity`;
- evaluate-only transform keeps `enforced_identity ==
  input_identity` because the rewrite is validated but not applied;
- runtime errors clear all three identity fields.

* fix(policy-engine): strict effects rejection + parity fixture for new D6 reasons

Round-2 multi-model review consensus blockers (small subset):

  - Strict AGT D1: reject any presence of the effects key on a
    verdict, including empty arrays and explicit nulls. The previous
    back-compat carve-out was loose; dispatchers MUST now drop the
    effects key entirely.
    Tests updated to assert empty[] and null both fail closed.

  - tests/parity/error_mapping_canonical.json was the only fixture
    not migrated by commit 335f7c7b. Added the 7 new D6 reasons
    (resolution_path_traversal/cycle/invalid_governance/merge_conflict,
    transform_target_forbidden, transform_invalid,
    approval_resolver_missing) and removed the deleted
    effect_invalid / effect_target_forbidden entries.

Larger SDK propagation blockers (Python + Node SDKs missing Transform
decision; FFI surfacing only action_identity not the new bisected
input_identity/enforced_identity) are dispatched separately to a
focused sub-agent.

Test suite: cargo 189 still passing 0 failing.

* test(policy-engine/core): align parity_canonical with strict effects fixture

asserted a 13-row fixture and only populated the runtime_errors map
with the pre-AGT 13 variants, so cargo test now fails closed at
canonical_error_mapping_matches_core_and_spec.

Update runtime_errors to map all 18 AGT-era variants byte for byte
with the fixture and accept their reason strings from either
SPECIFICATION.md or SPECIFICATION-AGT-DELTA.md (the AGT D5 and D6
reasons live in the delta document). The legacy EffectInvalid and
EffectTargetForbidden variants stay on RuntimeError for back-compat
but no longer appear in the parity fixture per AGT D1.

cargo test -p agent_control_specification_core now reports 189/189
passing, matching the M2 review baseline.

* feat(policy-engine/core/ffi): expose bisected identity and evidence on evaluate response

AGT D1.4 split the engine action identity into input_identity and
enforced_identity, and AGT D2 added optional verdict.evidence plus the
existing verdict.transform payload. core/src/runtime.rs already
populates all four fields on InterventionPointResult and Verdict, but
acs_runtime_evaluate only serialized action_identity, transformed
policy target, policy input, and the verdict's serde shape.

Extend the JSON response shape with input_identity and
enforced_identity. Keep action_identity as a backwards-compatible alias
for enforced_identity so older SDK bindings continue to deserialize a
well-formed result without a breaking change. verdict.transform and
verdict.evidence already ride through this response verbatim through
serde on Verdict; the policy callback in the roundtrip test now
exercises both fields.

ffi_roundtrip_transforms_policy_target now asserts:

- verdict.transform.path and verdict.transform.value are propagated
- verdict.evidence.artefact and verdict.evidence.verification_pointers
  are propagated verbatim
- input_identity and enforced_identity are both present and differ
  because the transform mutated the policy target
- action_identity equals enforced_identity for back-compat

ffi_roundtrip_allow_carries_evidence_and_matched_identities is added
to cover the non-transform path: an allow verdict carries the same
identity in both slots and still ships any evidence the dispatcher
attached.

cargo test -p agent_control_specification_core: 190 passing (189
baseline + 1 new FFI test). No tests regress.

* feat(policy-engine/sdk/python): support Transform decision + bisected identity + evidence

AGT D1 added the Transform decision as the sole mutating verdict, AGT
D1.4 split action identity into input_identity and enforced_identity,
and AGT D2 added an optional Evidence payload that high-assurance
dispatchers attach to a verdict. The Python SDK was still on the
pre-AGT shape and gated effects on applies_effects across allow, warn,
and escalate. Bring the SDK into line with the Rust core.

Types (_types.py)

- Decision.TRANSFORM is added; Decision.permits matches the Rust core
  (allow|warn|transform). Decision.applies_transform is the canonical
  mutating predicate (only TRANSFORM). Decision.applies_effects stays
  as a deprecated alias that returns applies_transform and emits a
  DeprecationWarning so out-of-tree callers see a clear migration
  signal.
- Transform dataclass mirrors core/src/verdict.rs::Transform with a
  from_mapping constructor.
- Evidence dataclass mirrors core/src/verdict.rs::Evidence with a
  from_mapping constructor that validates artefact type and pointer
  value types.
- Verdict now carries optional transform and evidence fields; the
  legacy effects sequence is removed because AGT D1 rejected it.
  Verdict.from_mapping parses both shapes and surfaces typed objects.
- InterventionPointResult now carries input_identity and
  enforced_identity per AGT D1.4. action_identity becomes a property
  alias that returns enforced_identity (the action that actually ran),
  satisfying AGT-EVIDENCE-1.0 §4's single-identity fallback.

Client (_client.py)

- NativeRuntimeClient.evaluate_intervention_point now reads
  input_identity and enforced_identity from the FFI response and
  falls back to action_identity when an older native binary only
  exposed the single field, so rollouts stay tolerant of stale
  bindings.

Orchestration (_orchestration.py, _adapters/_shared.py)

- _transformed_or now gates on applies_transform per AGT D1; ESCALATE
  no longer routes through a fallback that depended on the old
  applies_effects semantics. The litellm and openai adapter sites
  follow the same migration so streaming transforms only fire on a
  TRANSFORM verdict.

Tests (sdk/python/tests/)

- test_parity_canonical now reads the new permits column from
  verdict_dispatch_canonical.json and verifies the SDK surface for the
  new TRANSFORM row. The error_mapping_canonical assertion enumerates
  the seven AGT D5/D6 reserved reasons added by a9a9ddc8 and round-
  trips each through Verdict so the SDK does not choke on unknown
  reasons.
- test_escalate_allow_applies_effects_after_approval is replaced by
  test_transform_verdict_routes_through_transformed_policy_target,
  which proves the SDK uses the engine transform value without
  consulting an approval resolver.
- test_transform_evidence_identity.py is added: 14 tests covering
  Decision.TRANSFORM enum surface, Verdict.from_mapping parsing for
  transform and evidence, the deprecation warning on applies_effects,
  bisected identity persistence, action_identity property aliasing,
  end-to-end transform routing in enforce mode, evaluate_only
  bypassing transforms, warn-with-stale-target defence in depth, and
  evidence round trip from a native-shape response.
- Adapter test helpers default to Decision.TRANSFORM when a fixture
  supplies a transformed_policy_target so adapter call sites stay
  green under the tighter gate. QueueRuntime test fixtures move
  off the legacy single-identity replace pattern onto the bisected
  fields.

PYTHONPATH=. python -m pytest sdk/python/tests -q: 102 passed, 39
skipped (native bindings unavailable in this env). Baseline was 86
passed + 2 failed + 39 skipped, so this run nets +16 new tests with
the two prior parity failures cleared.

* feat(policy-engine/sdk/node): support Transform decision + bisected identity + evidence

Mirror the Python SDK migration (commit c6ce5793) on the Node side so
the TypeScript surface and the napi binding agree with the Rust core
shape produced by AGT D1, D1.4, and D2.

Wire surface (src/index.ts)

- Decision union gains 'transform' per AGT D1.
- Transform and Evidence types are added; Transform mirrors
  core/src/verdict.rs::Transform (path + value) and Evidence mirrors
  core/src/verdict.rs::Evidence (artefact + verificationPointers).
- Verdict now carries optional transform and evidence fields; the
  legacy effects[] array is removed because AGT D1 rejected it.
- InterventionPointResult carries inputIdentity and enforcedIdentity
  per AGT D1.4; actionIdentity remains a back-compat alias for
  enforcedIdentity (the action that actually executed).
- mapResult prefers the new bisected fields when the napi binding
  exposes them and falls back to action_identity for older binaries
  so rollouts stay tolerant of stale bindings.

Mutation gate (src/adapter-helpers.ts, src/streaming.ts)

- EFFECT_APPLYING_DECISIONS = [allow, warn, escalate] is replaced with
  TRANSFORM_DECISIONS = [transform]. Only TRANSFORM is allowed to
  mutate per AGT D1.
- appliesTransform is the canonical predicate; appliesEffects is a
  deprecated alias that delegates to it with a JSDoc deprecation note.
- transformedOr now gates strictly on appliesTransform. The streaming
  pipeline uses appliesTransform too so a post_model_call WARN with a
  stale transformedPolicyTarget cannot leak through.

napi binding (native/lib.rs)

- result_to_value adds input_identity and enforced_identity alongside
  the back-compat action_identity slot so the Node SDK consumes the
  same wire shape the Python SDK and FFI now produce.

Tests (sdk/node/test/)

- transform-evidence-identity.test.mjs is added: 9 tests covering the
  new Decision.Transform value, appliesTransform vs the deprecated
  appliesEffects alias, transformedOr gating allow|warn|deny|escalate
  out, evaluate_only bypass, bisected identity surface, Evidence round
  trip, end-to-end TRANSFORM routing without an approval resolver, and
  defence-in-depth dropping of stale transformedPolicyTarget on non-
  TRANSFORM verdicts.
- Existing adapter test stubs (adapters, adapter-mediation, ghcp,
  streaming-conformance) auto-pick Decision.Transform when a handler
  supplies a transformedPolicyTarget so call sites that exercised the
  old applies_effects gate stay green under the tighter mutation
  rule.
- escalation.test.mjs replaces the pre-AGT
  'escalate resolved to allow applies escalate effects after
  approval' case with a transform-routes-without-resolver test, since
  ESCALATE + transformedPolicyTarget is no longer producible under
  AGT D1.
- native-runtime.test.mjs and coding_assistant_use_case.test.mjs
  migrate every warn+effects[] fixture to transform+transform per AGT
  D1, including the dedicated 'transformedPolicyTarget +
  bisected identity' assertion for the native happy path.

Validation

- tsc -p tsconfig.json --noEmit: clean.
- node --test on all non-native test files: 49 passing
  (40 baseline + 9 new transform tests). The coding_assistant and
  native-runtime suites need the napi binary to load and are
  expected to remain skipped in environments without a built native.

* feat(policy-engine/integrations/otel): forward evidence and transformed counter per AGT D2

AGT D1 added the transform decision and AGT D2 added evidence
propagation to telemetry events per AGT-EVIDENCE-1.0 §3, including the
new intervention_point.transformed event. The OTel sink only knew
about the pre-AGT four-decision surface and dropped evidence on the
floor.

Bring the OTel integration into line with the core surface.

DECISION_WIRE_STRINGS

- Add 'transform' so the per-decision counter map ranges over all five
  AGT wire decisions (allow, deny, warn, escalate, transform). Without
  this entry the runtime's intervention_point.transformed event would
  have no counter to increment.

metric_attributes

- Add evidence_artefact: the verbatim artefact string from the
  originating verdict. Mirrors TelemetryEvent::evidence_artefact and
  AGT-EVIDENCE-1.0 §3.
- Add evidence_verification_pointer_keys: the sorted comma-joined list
  of verification pointer key names. The URL values themselves MUST
  NOT appear in telemetry per AGT-EVIDENCE-1.0 §3; auditors recover
  them from the audit record per §4.
- Both attributes are omitted when the verdict carries no evidence so
  the common no-evidence path stays clean.

Tests (in-crate)

- default_uses_canonical_meter_name asserts the per-decision counter
  count is 5 to lock in the new transform counter.
- mapping_omits_evidence_attributes_when_verdict_has_none locks the
  no-evidence path.
- mapping_includes_evidence_attributes_when_verdict_has_them verifies
  the verbatim artefact and sorted pointer keys land on the attribute
  list, and additionally asserts no attribute value contains an
  https:// URL to enforce the AGT-EVIDENCE-1.0 §3 cardinality rule.
- intervention_point_transformed_event_increments_transform_counter
  verifies the new event type emits an event_type of
  intervention_point.transformed, that the decision attribute is
  transform, that evidence rides through, and that the per-decision
  counter map contains a 'transform' entry so emit() finds a counter.

cargo test -p agent_control_specification_otel: 6 passing (was 3,
+3 new). cargo test -p agent_control_specification_core stays at
190 passing.

* fix(policy-engine/examples/bank_agent): migrate demo to transform verdicts

The rego template under policy/bank_agent_rego.rego was migrated to
return transform decisions for pre_model_call, post_tool_call, and
output in 335f7c7b, and the strict runtime in a9a9ddc8 now rejects
the legacy effects[] surface as runtime_error:policy_output_invalid.
The stdlib-only mock host under demo/run_demo.py still mirrored the
pre-AGT shape, so it failed to demonstrate the actual policy and
would fail closed in any setup that ran the rego policy through the
real runtime.

STAGE_FIXTURES

- pre_model_call now asserts decision == 'transform' (was 'warn').
- post_tool_call now asserts decision == 'transform' (was 'warn').
- output now asserts decision == 'transform' (was 'warn').
- agent_shutdown stays at 'warn' (the rego policy still warns there).

evaluate_policy

- pre_model_call returns transform with a single-target replace at
  .messages, mirroring the rego array.concat semantic.
- post_tool_call returns transform with a single-target replace at
  .account_id, mirroring the rego template.
- output returns transform with a single-target replace at
  .text computed via re.sub(CHK-[0-9]+,
  ACCOUNT-REDACTED, text), mirroring the rego regex.replace.
- Every non-transform decision now MUST NOT carry a transform; this
  invariant is asserted in enforce().

enforce

- Drops effects[]; the helper now consumes the transform key on a
  transform verdict and applies it via the new apply_transform
  helper. Fails closed with AssertionError on any of:
  - presence of effects[] (AGT D1 rejected the shape).
  - transform present on a deny / escalate verdict (AGT D1.1 ban).
  - transform present on a non-transform permitting verdict (allow
    or warn carrying a stale transform is a host-side bug).
  - transform missing on a transform verdict.

apply_transform

- New helper that walks .* via the existing path_tokens
  utility and replaces the value at the resolved path. The legacy
  apply_effect / apply_effects / account_redaction_effect helpers are
  retained as fail-closed stubs that raise AssertionError so any out-
  of-tree caller of the demo's legacy API surfaces a clear migration
  hint.

Manual run

- python examples/bank_agent/demo/run_demo.py prints
  'demo verification: PASS' and the user-visible output reads
  'I canno…
