* 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)

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.

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.

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

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

* 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.

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.
