Analysis complete. All confirmatory checks are consistent: the only matches for the deleted/relocated artifacts (`proof-receipt`, `tracker-sync-spikes`, ownership table, OWNER) live inside the completed task's own file or an unrelated spec (`fn-53.1`, out of scope — CROSS_SPEC is false); the single fn-82.2 hit in `fn-82.5.json` is just a `depends_on` edge, not a content reference. No glossary alias (`polling cycle`) anywhere.

Drift detected: no

**Phase 1–3 — completed task fn-82-skill-prompt-diet-progressive.2 (satisfies R5, R6):**
Pure Class-1 archaeology (deletion/prose-substitution, no behavior). Stripped ~90 `fn-NN` provenance tags from tracker-sync `SKILL.md`/`steps.md` (allowlist held; sole survivor `fn-42-foo` is a listing example), relocated linear/github/gitlab spike harnesses to `agent_docs/tracker-sync-spikes.md` (verified present; outside plugin tree, unmirrored), removed qa fn-53 scaffolding + the transient `proof-receipt.json` write, present-tensed map + memory-migrate, swapped flowctl.py line anchors for symbol names. Evidence: 390fe446, ff51dac. **No new names/APIs/data structures introduced** — nothing for downstream tasks to bind to; the one new artifact (`tracker-sync-spikes.md`) is unreferenced downstream.

**Phase 3b — glossary / decision / strategy signals:**
- 3b.1 (glossary): 38 terms, every entry `avoid: []` → no rename candidates.
- 3b.2 (decisions): 2 active entries. `factory-droid-platform-status` names capture/make-pr/setup/interview/plan + platforms.md/hooks.json — none touched by fn-82.2. `tracker-sync-is-projection` Consequences (status states, `land.merged`) — fn-82.2's allowlist deliberately *preserved* the rule-carrying refs (fn-66 merge-driver rewritten to prose), so archaeology aligns rather than contradicts. **None flagged.**
- 3b.3 (strategy): archaeology serves "Self-improving through normal work" / "Cross-platform parity" / "Ralph autonomous mode"; no track contradicted; Strategy-Alignment track names all present verbatim in current tracks → no rename. **No strategy drift.**

**Phase 4 — downstream tasks (.3 / .4 / .5):**
- fn-82.3 (R3,R6,R7): impl-review/spec-completion-review/interview/plan/audit/prospect — disjoint file scope; audit line-ref archaeology is the planned R6 split, not drift.
- fn-82.4 (R4,R8): make-pr/capture — disjoint scope.
- fn-82.5 (R9–R13): pins `tracker-sync SKILL.md+steps.md` and `qa SKILL.md+workflow.md` as token-table file-sets and regens the mirror once — these are correct-by-construction (the files fn-82.2 shrank); the `depends_on` edge to fn-82.2 is expected. No stale references.

**Phase 4b:** CROSS_SPEC = false → skipped.

**Phase 5 (DRY_RUN = true):** No files would be modified.
Traceability: parent spec's `## Requirement coverage` table already records `R5 → fn-82.2` and `R6 → fn-82.2 (qa/map/mm), fn-82.3 (audit line refs)` — matches actual implementation; no rows would change.

No downstream updates needed. No decision overrides or strategy drift to flag. No files modified.
