I've now completed all phases. Both decision entries' `## Consequences` sections name no files that fn-82.1 touched, and fn-82.1's changes are consistent with (in fact reinforce) both decisions — the completion-review touchpoint preserves "land.merged is the SOLE Done driver," matching the projection-not-coordination decision, and it adds no `.factory-plugin`/hook/plugin-root changes touching the Droid decision.

Summary of my analysis across all phases:

- **Phase 1–3 (drift):** fn-82.1's actual implementation matches its planned approach exactly. New files `references/tracker-touchpoints.md` and `references/qa-stage.md` exist; gate skeleton uses the spec's exact shape (`ACTIVE=0`, fail-open `|| ACTIVE=1` on both probe and parse, sentinel `GATE ACTIVE — STOP. Read …`); variable names `ACTIVE`/`QA_STAGE_ENABLED`/`QA_FRESH` are as planned; QA_FRESH consumer rows and Phase-5 sync-check stayed inline. No renamed API/variable/return-type that downstream tasks reference.
- **Phase 3b.1 (glossary):** all 38 glossary terms have empty `avoid` arrays — no aliases exist, so no in-flight rename possible.
- **Phase 3b.2 (decisions):** 2 active decisions; neither's Consequences names a file fn-82.1 modified, and fn-82.1 contradicts neither.
- **Phase 3b.3 (strategy):** 7 active tracks; fn-82.1 (prompt-diet gating/dedupe, zero new deps/SaaS/endpoints) serves Ralph/Cross-platform/Self-improving tracks and contradicts none. No track-rename candidate.
- **Phase 4 (downstream):** fn-82.2/.3/.4 touch disjoint skills (tracker-sync/qa/map/memory-migrate; impl-review/interview/audit/prospect; make-pr/capture) with no fn-82.1 name references. fn-82.5 references fn-82.1's gates by *content* (sentinel text, `|| ACTIVE=1`, reference filenames, always-loaded file sets) — all match the actual implementation. No stale references.
- **Phase 4b (cross-spec):** CROSS_SPEC=false → skipped.
- **Phase 5:** DRY_RUN=true; nothing to update. `## Requirement coverage` table maps R1/R2/R9→fn-82.1 exactly as built — no traceability change.

---

Drift detected: no
- fn-82.1 implemented its planned approach verbatim: gated `references/tracker-touchpoints.md` (work) + `references/qa-stage.md` (pilot), exact fail-open gate skeleton, forcing `GATE ACTIVE — STOP. Read` sentinel, variables `ACTIVE`/`QA_STAGE_ENABLED`/`QA_FRESH`, Phase-5 sync-check + 4-state summary + QA_FRESH consumer rows kept inline. No names/APIs/data structures changed relative to spec.

Would update (DRY RUN):
- None. No downstream task (fn-82.2, fn-82.3, fn-82.4, fn-82.5) references a stale name, API, filename, or file-set — they target disjoint skills or reference fn-82.1's gates by content, all of which match the implementation.

Would update traceability:
- None. `## Requirement coverage` already maps R1, R2, R9 → fn-82.1 (R9 + gate-check in fn-82.5); implementation covered exactly these. No scope change.

Decision overrides flagged for review:
- None. Both active decisions read; fn-82.1 touches none of their named files and reinforces (does not contradict) both.

No strategy drift flagged (7 active tracks scanned; fn-82.1 aligns with Ralph autonomous mode / Cross-platform parity / Self-improving, contradicts none).

No files modified.
