All four gate blocks (3 in work `phases.md`, 1 in pilot `workflow.md`) match the spec skeleton exactly: fail-open `|| ACTIVE=1` on both probe and parse, no `| jq` pipeline inside the gate (RAW captured first, parsed separately), the exact `GATE ACTIVE — STOP. Read` sentinel, and a bare default no-op. The two new reference files sit at the exact paths downstream tasks target.

Assessment complete. Verdict per phase:

- **Phase 3 (name/API drift):** fn-82.1 built exactly what R1/R2/R9 specified. Paths (`references/tracker-touchpoints.md`, `references/qa-stage.md`), gate vars (`ACTIVE`/`RAW`/`VAL`/`QA_GATE`), sentinel text, and section anchors all match the spec's gate skeleton. No naming divergence.
- **Phase 3b:** husk short-circuit N/A, but all three sub-signals come back clean — every glossary entry has `avoid: []` (no rename candidates); both active decisions are *preserved* by fn-82.1, not contradicted; the task serves the Ralph/Cross-platform/Self-improving tracks its own Strategy Alignment names and contradicts no track or the zero-external-dep approach.
- **Phase 4 (downstream tasks):** fn-82.2/.3/.4 touch disjoint skill files and reference the spec's patterns, not fn-82.1's concrete output. fn-82.5 references fn-82.1's output (gates, new refs, token-table sets) — all consistent with what actually landed (sentinel exact, one-level links, fail-open present, always-loaded file sets correctly exclude the new references).
- **Traceability table:** parent spec has a `## Requirement coverage` table; fn-82.1 delivered R1/R2/R9 with no scope change, so no rows are affected.

Drift detected: no
- fn-82-skill-prompt-diet-progressive.1 implemented exactly to plan (R1/R2/R9): moved work's tracker-touchpoint prose → gated `references/tracker-touchpoints.md` (anchors `#first-claim`/`#task-done`/`#completion-review`) and pilot's QA-freshness probe → gated `references/qa-stage.md` (`#qa-stage-freshness-probe`), each behind the spec's exact fail-open gate + `GATE ACTIVE — STOP. Read` sentinel. Paths, gate variables, sentinel string, one-level links, and section anchors all match the downstream assumptions.

Would update (DRY RUN):
- None. Downstream tasks .2/.3 touch disjoint skill files; .4 depends on .1 only as the gated-reference proof point (uses FOLD, not the gate skeleton); .5 references .1's output but every reference (new `references/*.md` paths, the `GATE ACTIVE — STOP. Read` grep target, work `SKILL.md+phases.md` / pilot `SKILL.md+workflow.md` token-table sets) is already consistent with what landed.

Would update traceability:
- None. `## Requirement coverage` rows R1/R2/R9 → fn-82.1 unchanged; no scope drift.

Decision overrides flagged for review:
- None. Both active decisions (tracker-sync projection-not-coordination; Factory Droid platform status) are preserved by the completed task, not contradicted.

Strategy drift flagged for review:
- None. The task advances the Ralph autonomous mode, Cross-platform parity, and Self-improving-through-normal-work tracks and contradicts no track or the zero-external-dependency approach.

No files modified (DRY_RUN=true; no drift found regardless).
