What & why

This PR fixes five related runtime and web regressions across prompt submission, observer authorization, loop settlement, process-exit classification, and manual Loop recovery.

Implementation was authored with Codex and reviewed through focused local tests. The broad repository gates are intentionally left to GitHub CI at the request of the maintainer; the exact local gate state is documented below.

Issue coverage

Closes #399

  • Send only the newest UI user message to the session prompt endpoint instead of replaying the entire persisted chat transcript.
  • Preserve the original message ID and prompt retry idempotency behavior.
  • Cover persisted user and assistant history plus a new message in the canonical transport suite.

Closes #415

  • Remove the duplicated permission-mode resolver path from the observer.
  • Resolve agents through the injected resource-backed agent catalog used by the daemon.
  • Build live snapshots from effective permissions and cache authorization by runtime identity and revision.
  • Keep stopped-session fallback snapshots shallow while preventing stale permissions from surviving a runtime revision change.

Closes #435

  • Distinguish a pre-commit lease-completion failure from a post-commit publication failure.
  • Fail a claimed run only when completion returned no committed run.
  • Preserve a committed terminal run when a later event publication step returns an error, preventing an invalid second settlement attempt.
  • Add task runtime and managed Loop coverage, including oversized completion results.

Closes #436

  • Classify non-zero and signaled ACP process exits as process failures.
  • Keep an empty-signal, zero-code exit on the transport-failure path.
  • Map process failures to the process-exited session cause while preserving the transport error for other fatal prompt failures.
  • Document the distinction in the session lifecycle guide.

Closes #437

  • Keep Loop-owned task crashes out of the generic subprocess health escalation path.
  • Project Loop worker attention into the existing Loop node control and event model.
  • Make task run recover preserve Loop ownership, workspace, designation, worktree, network, capabilities, and metadata.
  • Atomically fail the source run, create and link the recovery run, advance the exact node and item attempt and epoch, clear attention and death streak state, and append the existing recovery events.
  • Improve recovery diagnostics so needs-attention runs point to task run recover while active runs point to cancellation.

Design constraints

  • No database schema or migration changes.
  • No new config.toml keys, defaults, aliases, or compatibility paths.
  • Recovery uses the existing wait_intervention attention flag and existing Loop event vocabulary.
  • The new production recovery file is split by responsibility and stays below the 500-line source cap.

How you verified it

Focused checks passed locally:

  • Session fatal prompt regression under the Go race detector.
  • Full internal/observe package suite under the Go race detector.
  • Global database Loop recovery regression under the Go race detector.
  • Daemon Loop settlement, oversized-result, and subprocess-health regressions under the Go race detector.
  • Task recovery diagnostic and settlement regressions under the Go race detector.
  • Web session prompt transport suite through Turborepo: 5 tests passed.
  • Windows cross-compile check for the changed session and daemon packages.
  • git diff --check.
  • Commit hook completed successfully.

Broad gate state:

  • make gate Go lint lane: pass with zero issues.
  • The affected Go race suites passed through daemon, observer, session, store, and task packages.
  • The broad Go test lane reached internal/store/globaldb and hit the repository 10-minute package timeout in the existing TestGlobalDBTriggerEventHardCutMigration migration setup, without an assertion failure. The latest local gate record is therefore correctly marked failed.
  • A second run reproduced the same timeout.
  • make gate-full, repository-wide frontend checks, and real-user QA were not completed locally. GitHub CI is the requested source of broad validation for this PR.

Impact

User-visible surfaces

  • Web: session prompt submission now sends only the latest user message.
  • Runtime: process failures receive the correct terminal cause; post-commit settlement errors no longer overwrite committed results; observer permissions follow the active resource-backed agent revision; Loop-owned task runs can be recovered without losing ownership.
  • CLI: existing task run recover behavior is corrected for Loop-owned runs. No command name or argument schema changed.
  • HTTP and UDS: no route or wire-schema changes.
  • Documentation: updated session lifecycle, daemon operations, Loop failure handling, and the official Compozy skill references.

Compozy Impact Audit

  • Native tools: no compozy__* tool IDs, toolsets, descriptors, input or output schemas, digests, risk flags, or capability gates changed. The existing task recovery path was checked because it shares run recovery behavior.
  • Extensibility and hooks: no extension API, hook ID, bridge SDK, MCP sidecar, or new capability changed. Observer agent resolution now consistently uses the resource-backed catalog, including its existing global, workspace, and extension resource sources. Existing Loop attention and recovery events remain the contract.
  • Workspace data isolation: recovery validates that the task, source run, and Loop graph belong to the same workspace before mutation; observer resolution remains scoped to the session workspace and runtime identity. Coverage exercises preservation of workspace ownership and exact Loop node binding.
  • Official Compozy skill: updated skills/compozy/references/tasks-and-orchestration.md and skills/compozy/references/loops.md for recovery and crash ownership.

Web and docs impact

  • Changed web/src/systems/session/lib/session-prompt-chat-transport.ts and its canonical Vitest suite.
  • Updated packages/site/content/docs/sessions/lifecycle.mdx.
  • Updated packages/site/content/docs/operations/daemon.mdx.
  • Updated packages/site/content/docs/loops/failure-handling.mdx.

  • make gate passes locally; broad validation is delegated to GitHub CI as documented above
  • New and changed behavior is covered by focused regression tests
  • Codex contribution is named above and the staged result was inspected before publication

Walkthrough

The changes update Loop lease settlement and recovery, observer agent resolution and session caching, provider-auth metadata, prompt failure classification, and Web prompt request construction. Tests cover oversized results, Loop recovery, observer refresh behavior, session failures, and latest-message transport.

Changes

Loop execution and recovery

Layer / File(s) Summary
Action result validation and lease settlement
internal/daemon/loop_action_liveness_integration_helpers_test.go, internal/daemon/loop_action_runtime.go, internal/daemon/loop_goal_managed_runtime_integration_test.go, internal/daemon/task_runtime_test.go
Oversized action results now fail task runs and release leases. Completion errors distinguish pre-commit failure from post-commit publication failure.
Confirmed crash escalation behavior
internal/daemon/subprocess_health_escalator.go, internal/daemon/subprocess_health_escalator_test.go
Confirmed crashes no longer escalate Loop-worker runs.
Loop attention persistence and recovery routing
internal/loop/node_liveness.go, internal/store/globaldb/global_db_task_aux.go, internal/store/globaldb/global_db_task_reservation.go, internal/store/globaldb/global_db_task_mutation_runs.go, internal/store/globaldb/global_db_task_force.go, internal/store/globaldb/global_db_loop_task_attention.go, internal/store/globaldb/global_db_loop_test.go
Needs-attention transitions project Loop state, preserve queued-run metadata, and route Loop-worker recovery through the Loop recovery executor.
Loop task recovery state transitions
internal/store/globaldb/global_db_loop_task_recovery.go, internal/store/globaldb/global_db_loop_task_recovery_metadata.go, internal/store/globaldb/global_db_task_test.go
Recovery validates Loop bindings, creates a linked continuation, advances generation output, clears attention, records the attempt, and emits Loop events.
Operator recovery command contract
internal/task/force_ops_request_normalization.go, internal/task/manager_run_terminal_settlement.go, internal/task/run_mutation.go, internal/task/manager_test.go
Needs-attention diagnostics recommend recovery. Active-run diagnostics use compozy task run cancel. Recovery commands retain their admission timestamp.

Observer agent resolution

Layer / File(s) Summary
Observer agent resolver integration
internal/daemon/agent_skill_catalog.go, internal/daemon/agent_skill_resources_test.go, internal/daemon/runtime_deps.go, internal/daemon/runtime_dependencies.go, internal/daemon/observer_factory.go, internal/observe/agent_resolution.go, internal/observe/observer.go, internal/observe/helpers_test.go
The observer receives the daemon agent resolver. Resolution uses workspace snapshots, catalog matches, and built-in definitions. Catalog revisions are exposed for cache invalidation.
Live session identity and resolution caching
internal/observe/observer_session_events.go, internal/observe/observer_test.go
Live sessions track runtime, permission, provider-auth, and catalog revisions. Cached snapshots are reused only when the runtime identity remains unchanged.
Observer metadata and notification snapshots
internal/observe/observer_session_metadata.go, internal/session/notifier.go
Session metadata lookup validates identifiers and paths. Notification snapshots are detached and include session state fields.

Session state and failure classification

Layer / File(s) Summary
Provider authentication state propagation
internal/store/session_meta_types.go, internal/session/session.go, internal/session/session_meta.go, internal/session/manager_start_session.go, internal/session/manager_permissions_test.go
Sessions store effective provider authentication mode and expose it through persisted metadata.
Prompt stop-cause and process-exit mapping
internal/session/manager_prompt_failure_barrier.go, internal/session/manager_prompt_process_exit.go, internal/session/manager_prompt_contract_test.go
Fatal prompt failures retain failure-specific stop causes. Clean subprocess exits after transport failures are classified as transport failures.

Web prompt transport

Layer / File(s) Summary
Latest-message request construction
web/src/systems/session/lib/session-prompt-chat-transport.ts, web/src/systems/session/lib/__tests__/session-prompt-chat-transport.test.ts
Prompt requests now send only the latest user message. The request ID and preparation callback use that same message.

Greptile Summary

This PR repairs runtime recovery behavior across session prompts, observer authorization, Loop settlement and recovery, and ACP process-exit handling.

  • Sends only the newest web chat message while retaining prompt identity and retry semantics.
  • Refreshes live observer authorization by catalog/runtime revision and persists effective authorization for stopped-session recovery.
  • Preserves committed Loop settlements after publication failures and adds Loop-owned task recovery.
  • Separates ACP process exits from transport failures and adjusts subprocess-health escalation.

Confidence Score: 4/5

The PR is not yet safe to merge because late events for legacy stopped native-CLI sessions still receive incorrect cost classification.

Stopped-session recovery reads authorization only from a newly added optional metadata field, so existing session metadata yields an empty mode and bypasses native-CLI included-cost handling.

Files Needing Attention: internal/observe/observer_session_events.go, internal/store/session_meta_types.go

Important Files Changed

Filename Overview
internal/observe/observer_session_events.go Adds catalog-aware live snapshot refresh and richer stopped-session recovery, but legacy metadata still loses provider authorization during late-event processing.
internal/observe/agent_resolution.go Routes observer resolution through the daemon’s resource-backed agent catalog and exposes its revision for cache invalidation.
internal/store/session_meta_types.go Adds optional persistence for effective provider authorization while retaining compatibility with older JSON metadata.
internal/daemon/observer_factory.go Injects the daemon-authoritative agent resolver into observer construction.

105-131: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Add builtin and nil-workspace fallbacks to ResolveAgent. resourceAgentCatalog.ResolveAgent does not call BuiltinAgentDef. It also returns ErrAgentNotAvailable for a nil workspace unless a matching global catalog record exists. Builtin agents can therefore fail provider-auth resolution through this resolver.

Preserve session metadata during registry recovery.

store.SessionInfo contains Model but no EffectivePermissions. This branch drops Model and bypasses auth resolution, so usage costs can fall back to unknown and permission events are skipped because permissionMode is empty. Recover these values from authoritative persisted metadata before caching the snapshot.

Validate the context at the top of trackLiveSession.

observedSessionSnapshot calls requireObserverContext, but trackLiveSession returns early on a cache hit at Line 247 and never reaches that check. A nil context therefore panics only when the cache misses. Move the check to the entry point so the behavior is deterministic.

 func (o *Observer) trackLiveSession(ctx context.Context, info *session.Info) observedSession {

82-92: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Isolate the runtime revision change so the test can detect a regression in that field.

Lines 82 and 83 change RuntimeSelectionRevision and Model together. sameRuntimeIdentity compares six fields, so this assertion cannot show which field triggered the refresh. The test would still pass if runtimeRevision were removed from sameRuntimeIdentity. Issue #415 targets revision-aware caching specifically, so add a step that changes only the revision.

💚 Proposed test change
 		sess.RuntimeSelectionRevision++
-		sess.Model = "claude-next"
 		h.observer.OnAgentEventForSession(testutil.Context(t), sess, acp.AgentEvent{
 			Type:      "agent_message",
 			TurnID:    "turn-cache-runtime-change",
 			Timestamp: h.now.Add(3 * time.Minute),
 			Text:      "runtime changed",
 		})
 		if got := resolver.calls.Load(); got != 2 {
 			t.Fatalf("ResolveAgent() calls = %d, want 2 after runtime identity change", got)

19-84: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Consider splitting attention projection and metadata helpers into their own files.

This new file holds three distinct responsibilities: needs-attention projection (lines 19-84), recovery state transitions (lines 86-153 and 267-439), and metadata merge helpers (lines 216-265). The file is 439 lines, so it is close to the 500-line cap and cannot absorb further growth.

Split it now: keep recovery transitions here, move projectLoopTaskRunAttentionWithExecutor to a Loop attention file, and move loopTaskRecoveryMetadata and mergeLoopTaskMetadata to a named helper file.

As per coding guidelines: "Keep one cohesive responsibility per production file and cap production Go files at 500 lines; split contracts, wiring, implementations, and helpers."

Refresh ID-only event snapshots after a catalog change.

Line 39 refreshes OnAgentEventForSession, but OnAgentEvent can hit validateObservedEvent with an existing cached snapshot and skip recovery. After the catalog revision changes, that path can use the old authorization snapshot.

Before accepting a cached snapshot on the ID-only path, compare its agentCatalogRevision with o.agentCatalogRevision() and recover it when they differ. Add a direct OnAgentEvent test that changes the resolver revision after the initial cache.

Define this interface in internal/observe.

Observer.agentCatalogRevision is the supplied consumer. Keep the interface private next to that type assertion. resourceAgentCatalog will satisfy it implicitly. This avoids making session own an observer cache contract.

As per coding guidelines, “Define interfaces where they are consumed”.

P1 Legacy auth mode remains empty

When a stopped session created before effective_provider_auth_mode was persisted receives a late event, this recovery path treats the absent field as an empty auth mode. Native-CLI usage then enters catalog cost estimation or becomes unknown instead of being recorded as provider-included.
