feat(factory): emit completed-session replay pointers

[khaliqgant]

Refs AgentWorkforce/relay#1522
Refs #260

Summary

• emit the ruled three-key trajectory marker on every PR Factory opens, using the existing Relay-emitted session_ref
• export an SDK parser for the marker without treating UUID syntax as live replay availability
• reject missing, placeholder, unsafe, and nil values as resolver input and emit session_ref=missing instead
• strip inherited trajectory markers before appending one canonical pointer

Retention boundary

Pointer format was agreed with the relay lane before implementation: AgentWorkforce/relay#1522 (comment)

Factory carries the reference only. It does not freeze a replay command, expiry, or availability claim into the PR body. The authenticated @agent-relay/session resolver owns the live retained-since/never-prune boundary and must mark aged-out conversation coverage incomplete instead of rendering it as replayable. This keeps a PR opened weeks earlier from making a stale coverage claim.

The relay-side production dependency documented on relay#1522 remains separate; this PR does not claim the Relaycast join is shipped.

Verification

• npm ci
• focused replay-pointer and PR-publication tests: 14 passed
• npm run build
• npm run featuremap:check (321 features, no advisories)
• npm test: 96 files passed, 1 skipped; 1,766 tests passed, 1 skipped
• built SDK read-back reproduced the exact marker and parsed work_unit_id, work_unit_surface, and session_ref
• git diff --check

Merge policy: never — review only.

Summary by cubic

Emits a ruled three-key trajectory pointer in every Factory-opened PR so Relay can render live, retention‑aware session replays. Previously PRs had no canonical pointer; now Factory strips inherited markers and appends one reference‑only pointer at publish time.

• Pointer format: ; work_unit_id is AR‑52 for Linear, owner/repo#number for GitHub, or factory: for Factory.
• Session refs: accepts only Relay‑emitted session UUIDs; otherwise writes session_ref=missing. The body never includes a replay command or a retention claim. Publish payload passes implementer.sessionRef through when set, even if the body renders session_ref=missing.
• SDK: exports canonicalTrajectorySessionRef, MISSING_TRAJECTORY_SESSION_REF, renderTrajectoryPointer, stripTrajectoryPointers, trajectoryPointerFromBody, trajectorySessionRefFromBody, and types; docs added in docs/pr-session-replay.md; feature catalog updated.
• Required action for live session refs: set implementer.sessionRef or RELAY_ATTEST_SESSION_ID to a Relay UUID; otherwise pointers render session_ref=missing and the resolver decides availability at read time.

Connected to Linear issue relay#1522.

📝 Walkthrough

Walkthrough

This change adds canonical trajectory pointers for completed-session pull requests. It validates and normalizes pointer metadata, removes inherited markers, derives work-unit identifiers, and publishes session references without legacy replay content.

Changes

Trajectory replay pointer

Layer / File(s)	Summary
Pointer contract and utilities src/trajectory.ts, src/trajectory.test.ts, src/index.ts	Defines pointer types and helpers for validation, rendering, parsing, session-reference extraction, and marker removal. Tests cover missing or unsafe references, conflicts, and unsafe work-unit tokens.
Pull request publication integration src/orchestrator/factory.ts, src/orchestrator/factory.test.ts, docs/pr-session-replay.md, .agentworkforce/features/manifest.yaml	Factory derives work-unit metadata, normalizes pull request bodies, appends one trajectory pointer, and tests explicit or missing session references. Documentation and the feature manifest describe the pointer contract.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 8af2f

The change is mergeable with owner awareness: the public SDK export is not listed in the feature manifest, which may leave feature tracking incomplete, but no concrete runtime or user-facing failure is indicated.

Poem

I mark each trail with careful cheer,
A session path made bright and clear.
Old hidden pointers hop away,
One canonical mark will stay.
