Confirmed. The implementation matches the spec, and I've verified the full downstream-reference picture. Summary of findings:

- **fn-82.3 actual implementation** landed as specified: impl-review/spec-completion-review delegate Phase 0 to the pre-existing always-loaded `workflow-common.md` (one `review-backend` call/run); interview walker single-sourced into the **plugin-level** `plugins/flow-next/references/spec-template-discovery.md` — the same already-mirrored dir as `html-artifacts.md` (no parity risk), with `plan/steps.md` + `docs/spec-template.md` repointed.
- **fn-82.4** (make-pr fold + capture dedupe) touches a fully disjoint file set — references nothing from fn-82.3.
- **fn-82.5** references fn-82.3's skills only via generic, still-accurate hooks: the R12 token-table pinned file sets (impl-review/completion-review `SKILL.md+workflow-common.md`; interview `SKILL.md`; audit `…workflow.md+phases.md`; prospect `SKILL.md+workflow.md`) all remain correct — the dedupe moved content *between* already-always-loaded files and moved the interview walker *out* to an on-demand reference, so no always-loaded set changed. The R11 "new references/*.md" mirror regen is already generic. No stale name/path/API.
- **Phase 3b:** all 38 glossary entries have empty `avoid` (no rename signal); both active decisions' Consequences name no code fn-82.3 contradicts (droid decision wants `.factory-plugin` fallback *removed* — fn-82.3 doesn't re-add it; tracker-sync decision is unrelated subsystem); strategy tracks are *served* by a token-diet pass, not contradicted, and no `### H3` track-rename alias appears.
- **Traceability:** parent spec's `## Requirement coverage` assigns R3/R6/R7 to fn-82.3, matching its `satisfies` frontmatter exactly — no coverage drift.

Drift detected: no

**Completed task fn-82-skill-prompt-diet-progressive.3** (`satisfies: [R3, R6, R7]`) implemented its Class-3 dedupe as specified. Verified against actual code (commit `1d668d35`): review-skill Phase-0 delegation, interview walker relocation, audit/prospect dedupe all landed with no naming/API/structure divergence from the plan.

Would update (DRY RUN):
- **None.** Neither downstream task requires changes.
  - `fn-82.4` (make-pr/capture eval pair) — disjoint file set; references no fn-82.3 deliverable.
  - `fn-82.5` (final gate) — its token-table file-set pins and "new references/*.md" mirror-regen references remain accurate post-implementation (the new reference sits in the established, already-mirrored `plugins/flow-next/references/` dir; no always-loaded set changed).

Would update traceability:
- **None.** `## Requirement coverage` rows R3/R6/R7 already map to fn-82.3, matching its `satisfies` — no drift.

Decision overrides flagged for review:
- **None.** 2 active decisions checked; neither's `## Consequences` names code that fn-82.3 contradicts.

Strategy drift flagged for review:
- **None.** The token-diet pass aligns with (does not contradict) the active tracks; no track-rename alias present.

No files modified (DRY_RUN).
