-- Rate-family "recognized_no_injection" bucket reduced or its refusal mode made actionable (e.g. surfaces the true next blocker like denom reachability).
+- Inc3 ratified change merged (#799).
+- Live ephemeral frontier: `rate_with_currency` no-injection = 0; aggregate proxy 6/44/0, wrong=0.
+- Pinned `report.json` may remain historical; live measurement via ephemeral runner or synthetic frontier tests.
+- Inc3 lookback committed (docs/analysis/gsm8k-workstream-a-increment-3-lookback-2026-06-17.md).
 - No rebaseline of sealed lanes or SHA movement without separate ratification.
-- Documentation (this roadmap + Inc3 ratification) committed as docs-first.
 
-## Out of Scope (for Inc3)

 - Full comparative (Gate A1) implementation.
-- Broad recognizer anchor work or other shape categories.
-- Changes to serving sealed paths.
-- Any mutation of identity, policy, or algebra invariants.

+# GSM8K Workstream A Increment 3 — rate followup lookback
+
+**Date:** 2026-06-17 (post-merge evidence closure)
+**Branch (implementation):** feat/gsm8k-workstream-a-inc3-rate-followup (merged as PR #799)
+**Head (merged on main):** 8a981e66c716f020b5558c584d39084fadee5011
+**Governing ratification:** docs/analysis/gsm8k-workstream-a-increment-3-rate-followup-ratification-2026-06-17.md
+**Evidence-closure PR branch:** docs/gsm8k-workstream-a-inc3-lookback (this lookback + test semantics; no runtime logic)
+
+## What shipped (PR #799 merged)
+
+Inc3 closed the post-#797 rate connector blocker: the `"one"` token in **for one <unit>** rate surfaces is now a valid `apply_rate` rate anchor.
+
+### Exact semantic path
+
+1. **Matcher** (`generate/recognizer_match.py`): when the currency-per-unit regex captures connector `q`, if `q in ("each", "every", "a", "one")` then `connector = q` and `rate_anchor_token` is set to that literal (e.g. `"one"` for *for one cup*).
+2. **Roundtrip whitelist** (`generate/math_roundtrip.py`): `RATE_ANCHORS` includes `"one"` alongside `per`, `each`, `every`, `a`, `an`.
+3. **Injector** (`generate/recognizer_anchor_inject.py`): `inject_rate_with_currency` accepts `rate_anchor_token in ("per", "each", "every", "a", "an", "one")`; on success emits `CandidateOperation(kind="apply_rate", operand=Rate(...))` with `matched_verb` grounded to the literal connector.
+
+No other runtime modules changed solver semantics, sealed lanes, graph construction, or serving policy.

+
+## Measurement truth (pinned vs live)
+
+### Pinned committed artifact (historical / stale for rate bucket)
+
+`evals/gsm8k_math/train_sample/v1/report.json` remains the **pre-Inc2/Inc3 runner output** committed at the Inc1 rebaseline:
+
+- **6 correct / 44 refused / 0 wrong**
+- `recognized_no_injection_by_category.rate_with_currency: 3` (Tina *an hour*, Alexa *for one cup*, Erica *per kg* still show injector-level no-injection strings)
+
+This artifact is **intentionally not rebaselined** in Inc3 or this evidence-closure PR. Frontier script analysis on the pinned file still reports `rate_with_currency: 3` — that is expected and documents the historical measurement surface Inc2 targeted.
+
+### Live ephemeral runner (current main code, not committed)
+
+`build_report(cases)` on current main (ephemeral invocation; no `report.json` write):
+
+| Metric | Value |
+|--------|-------|
+| correct | 6 |
+| refused | 44 |
+| wrong | 0 |
+| `rate_with_currency` in `recognized_no_injection` | **0** |
+| total `recognized_no_injection` | 31 (was 32 on pinned artifact) |
+| live `recognized_no_injection_by_category` | `discrete_count_statement: 19`, `temporal_aggregation: 2`, `multiplicative_aggregation: 3`, `descriptive_setup_no_quantity: 4`, `currency_amount: 3` |
+
+**Interpretation:** rate surfaces no longer refuse at the injector boundary. Refusal moved **downstream** (e.g. `no admissible candidate for statement`, `no branch produced a solvable graph`) because denom-state / composition blockers remain. This matches Inc3 ratification §2: actionable evidence, not correct-count lift.
+
+`evals/gsm8k_math/train_sample/v1/refusal_rescan_v3.json` corroborates Tina/Alexa cases: `current_refusal_reason` is `no admissible candidate for statement`, not `produced no injection`.
+
+## wrong=0
+
+- Pinned artifact: `wrong: 0`
+- Live ephemeral runner: `wrong: 0`
+- Inc3 unit/graph tests exercise confusers; no wrong answers admitted on exercised paths.
+
+## Explicit non-changes (Inc3 scope held)
+
+- **No** `report.json` rebaseline committed
+- **No** denominator-state production (hour/kg/cup Initial seeding)
+- **No** comparative injection / Gate A1
+- **No** sealed-lane movement (`_SEALED_INJECTORS` remains empty; train_sample uses `sealed=False`)
+- **No** serving SHA / CLAIMS movement
+- **No** `determine()` / FrameVerdict / CLOSE interaction
+- **No** corpus/pack/policy/identity mutation
+- **No** solver `_apply_rate` semantic change
+
+## Known caveats
+
+1. **Aggregate proxy unchanged:** still 6/44/0 and `passed=false` (`correct_min=10`). Inc3 did not claim net correct lift.
+2. **Refusal-family reclassification:** rate cases may move from `recognized_no_injection` to `no_admissible_statement` or graph unsolvability — not to `correct`.
+3. **Pinned frontier tests:** tests that read committed `report.json` encode the **historical** rate bucket (3× no-injection). Live-behavior tests use ephemeral `build_report` or synthetic fixtures (see `tests/test_gsm8k_frontier_report.py`).
+4. **Erica / denom reachability:** third rate case may still refuse downstream for actor/denom reasons; connector fix does not solve inverse *for one cup* pricing semantics.
+5. **Inc3 lookback was missing until this PR:** ratification landed with #799; lookback + roadmap status update closes the governance loop before Gate A1 ratification.
+
+## Loop-closure criterion (for Gate A1 readiness)
+
+The post-#797 rate follow-up loop is **closed** when all of the following hold:
+
+1. PR #799 merged with `"one"` connector in matcher + roundtrip + injector (**done**).
+2. Live ephemeral frontier shows `rate_with_currency` no-injection = **0** (**done** on current main).
+3. `wrong_total == 0` on train_sample proxy (**done**).
+4. This lookback + roadmap status committed; frontier tests distinguish pinned historical artifact from live post-Inc3 behavior (**this PR**).
+5. No `report.json` rebaseline unless separately ratified (**held**).
+
+Gate A1 comparative ratification may proceed after this evidence-closure PR merges.

+
+## Post-merge obligations
+
+- Ratify Gate A1 multiplicative comparative injection (docs-only) before any comparative code.
+- Preserve wrong=0, sealed discipline, and ratify-first on all Workstream A follow-ons.
+- Do not treat pinned `report.json` rate bucket as live-state without ephemeral runner corroboration.
+
+This lookback is truthful to merged #799 behavior, the stale pinned artifact, and ephemeral live measurement. No benchmark theater; no hidden rebaseline.
