I have everything I need. Let me confirm my analysis before writing the summary.

**Phase 1–3 (drift):** fn-9.1 spec said implement helper named `parse` in `src/reader.py`. Done summary: shipped as `read` instead. Actual code confirms `def read(line):` in `src/reader.py`. → Name drift: `parse` → `read`.

**Phase 3b (husk short-circuit):** GLOSSARY `total_terms == 0`, DECISIONS `count == 0`, STRATEGY `== {}` — all three hold → entire Phase 3b skipped. No glossary/decision/strategy signal.

**Phase 4 (downstream):** fn-9.2 line 8 — "Feed each line through the **parse** helper before adding it as a row." → stale reference to the renamed helper. (`Render reader output` and `the helper output` are generic, not stale.)

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

**Phase 5 (traceability):** parent spec `fn-9.md` has no `## Requirement coverage` table → sub-step skipped. R1 coverage unchanged (pure rename; no `satisfies` change warranted).

---

Drift detected: yes
- fn-9.1 shipped the line helper as `read` (in `src/reader.py`), not `parse` as the fn-9.1 spec specified. Done summary + actual code (`def read(line):`) confirm the in-flight rename.

Would update (DRY RUN):
- **fn-9.2** (`.flow/tasks/fn-9.2.md`, line 8): change "Feed each line through the `parse` helper before adding it as a row." → "...through the `read` helper...". Add breadcrumb `<!-- Updated by plan-sync: fn-9.1 used read not parse -->`. Scope/acceptance preserved; no `satisfies` change (pure name drift, R1 coverage unchanged).

Would update traceability:
- None — parent spec `fn-9.md` has no `## Requirement coverage` table.

Phase 3b (glossary / decisions / strategy): skipped via husk short-circuit — no glossary terms, no decision entries, no STRATEGY.md signal.
