I have everything needed. Let me trace through the phases.

**Phase 1 — Re-anchor (fn-9.1):** Spec said ship `AuthResult` with a `token` attribute in `src/auth/result.py`. Done summary: field renamed to `access_token` (OAuth vocabulary); `AuthResult.token` no longer exists. Evidence commit: `8e3b64f`.

**Phase 2 — Actual implementation** (`src/auth/result.py`): `AuthResult.__init__(self, access_token)` → `self.access_token`; `login(tok)` returns `AuthResult(access_token=tok)`. Confirms `token` → `access_token`; no `.token` attribute exists.

**Phase 3 — Drift:**

| Aspect | Spec Said | Actually Built |
|--------|-----------|----------------|
| Field name | `AuthResult.token` | `AuthResult.access_token` |

**Phase 3b — Husk short-circuit:** `GLOSSARY_JSON.total_terms == 0` ✓, `DECISIONS_JSON.count == 0` ✓, `STRATEGY_CONTENT == {}` ✓ — all three hold, so Phase 3b is skipped entirely (no glossary/decision/strategy signal).

**Phase 4 — Downstream (fn-9.2):** Body says "persist the **AuthResult.token** value into the session map." Stale reference — the field is now `access_token`.

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

**Phase 5 (DRY_RUN=true):** Report only. Parent spec `fn-9.md` has no `## Requirement coverage` table → traceability sub-step skipped. (Note: `fn-9.md` Approach line also says fn-9.1 ships a `token` field, but spec edits are restricted to the traceability table only, and none exists — not in scope.)

---

Drift detected: yes
- fn-9.1 renamed the `AuthResult` field from `token` to `access_token` (OAuth vocabulary). Confirmed in `src/auth/result.py`: `AuthResult(self.access_token)`; `AuthResult.token` no longer exists.

Would update (DRY RUN):
- fn-9.2 (`.flow/tasks/fn-9.2.md`): change the line "persist the `AuthResult.token` value into the session map" → "persist the `AuthResult.access_token` value into the session map"; add breadcrumb `<!-- Updated by plan-sync: fn-9.1 used access_token not token -->`

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

Decision overrides flagged for review:
- None (DECISIONS_JSON husk).

Strategy drift flagged for review:
- None (STRATEGY_CONTENT husk).
