## Non-adoption / insufficiency

This is a **corrected proposal** after ChatGPT source inspection of v0.3.3. Do **not** treat as accepted executable protocol. Exp002 v0.3 **INSUFFICIENT_FOR_INFERENCE** remains binding. No empirical full-series rerun · no new N_ep/B1 counts · no ratchet/scoring/lowered gate.

## Fixes vs v0.3.3 (explicit)

| # | Issue | Resolution in v0.3.4-draft |
|---|-------|------------------------------|
| 1 | Case C confirmed at t=805 after **four** post-onset polls; only t=803 qualifies among first three. Table appended hits until K **without** original next-3 / 540-day boundary | **PRIMARY** confirmation restored: **K=2 of next N=3** post-onset polls ≤ B0−D/2 within **540 days**, **OR** immediate-next ≤ B0−D. Unbounded append is a **named non-default variant** only (`VARIANT_UNBOUNDED_APPEND_UNTIL_K_NOT_DEFAULT`). Case C under primary → `CENSORED` / `confirm_window_exhausted_K_of_next_N` (does **not** confirm). |
| 2 | Confirm with no crossing → immediate `CENSORED_NO_CROSS` | New state **`CONFIRMED_UNRECOVERED`**: continue for recovery until `R_followup_max_polls=6` or `R_days_max=540` after T_confirm; then `CENSORED_NO_CROSS`. Test G = confirmation-first / recovery-later. |
| 3 | Refractory restart underspecified; EOS used as timeout stand-in | **`refractory_polls=1`** (next onset search begins on poll after close); baseline **STRICTLY_TRAILING_M recomputed** at new onset; Test I multi-episode. **Test E2** = explicit 540d confirm timeout; **Test E** = EOS only. |
| 4 | Claude `7a7c35f8` defined HISTORICAL as “crossing before confirmation”; Grok Case A is CURRENT despite earlier crossing because x≥r50 | **Binding:** `RECOVERED_CURRENT` iff `x_at_confirm ≥ r50`; `RECOVERED_HISTORICAL` iff confirmed with prior `T_cross_obs` and `x_at_confirm < r50`. Audit flag `cross_preceded_confirm` is diagnostic only. **Rejected:** equating early crossing with HISTORICAL. |
| 5 | Runnable source + hashes missing | This packet ships executable Python + full_inputs + sha256 per case. |

---

## Baseline rule freeze (proposal; unchanged intent)

**STRICTLY_TRAILING_M** with default `M=8` (sensitivity `M ∈ {6,10}`).  
Do **not** use max-within-2920-days unless registered as a separate variant.  
After lock, **recompute all baselines** — not only E005.

Confirm hits: polls **after** onset only (onset poll itself does not count toward K). Onset poll ordinal for the confirm window starts at the **first post-onset** poll.

---

## State set

| State | Meaning |
|-------|---------|
| `SEEK_ONSET` | Idle; waiting for `x ≤ B0−D` with valid baseline |
| `PENDING` | Onset seen; episode **not** declared. Track xmin, provisional r50, trough, crossing candidates. **Do not emit recovery events.** |
| `CONFIRMED_UNRECOVERED` | K-confirm (or immediate-next) reached; **no** `T_cross_obs` yet. Wait for later recovery within follow-up limits. |
| `RECOVERED_CURRENT` | Confirmed **and** crossed; at decision of recovery label, `x ≥ r50` (at `T_confirm` if cross≤confirm, or at later cross if recovery-after-confirm) |
| `RECOVERED_HISTORICAL` | Confirmed with prior cross; at `T_confirm`, `x_at_confirm < r50` |
| `RELAPSED` | Was `RECOVERED_CURRENT`, then `x < r50` |
| `CENSORED` | Confirm window exhausted / 540d timeout / EOS before K |
| `CENSORED_NO_CROSS` | Confirmed unrecovered follow-up limit exhausted (or EOS while unrecovered) |

Three times (v0.3.2, unchanged): `T_cross_obs` (primary) · `T_confirm` · `T_recovery_recognized = max(...)` (secondary).

---

## Confirmation rule (PRIMARY — no silent broadening)

```
immediate-next: first post-onset poll has x ≤ B0−D
   OR
K-of-next-N: among the next N=3 post-onset polls, ≥ K=2 have x ≤ B0−D/2
   AND decidable time is within confirm_days=540 after onset_day
```

Hits with post-onset ordinal > N are **ignored** for confirmation (`CONFIRM_HIT_OUTSIDE_WINDOW_IGNORED`).  
Variant `N→∞` / append-until-K is **not default** and must be named if used.

---

## Deterministic transition table

Per-arrival order: ingest → trough revise → confirmation bookkeeping → crossing record → state → recognition record.

| From | Trigger (forward-only) | To | Side effects |
|------|------------------------|----|--------------|
| SEEK_ONSET | valid B0 and `x ≤ B0−D` | PENDING | Set onset; xmin:=x; r50:=B0−0.5(B0−xmin); confirm window opens; no recovery emit |
| PENDING | deeper `x < xmin` before confirm | PENDING | Default `revise_on_deeper_trough`: reset xmin/r50; **clear** prior `T_cross_obs` |
| PENDING | `x ≥ r50` and trough established and no cross yet | PENDING | Record `T_cross_obs` + (last-below, first-above] **audit-only** |
| PENDING | confirm rule decidable **with** cross | RECOVERED_CURRENT / RECOVERED_HISTORICAL | CURRENT iff `x_at_confirm ≥ r50` else HISTORICAL |
| PENDING | confirm rule decidable **without** cross | CONFIRMED_UNRECOVERED | Do **not** censor yet |
| PENDING | next-N exhausted without K, or day−onset_day > 540 | CENSORED | `confirm_window_exhausted_*` / `confirm_window_timeout_540d` |
| PENDING | end of series before K | CENSORED | `end_of_series_before_K_confirm` (**≠ timeout**) |
| CONFIRMED_UNRECOVERED | later `x ≥ r50` | RECOVERED_CURRENT | `RECOVERY_AFTER_CONFIRM`; set `T_cross_obs` |
| CONFIRMED_UNRECOVERED | follow-up poll/day limit | CENSORED_NO_CROSS | Only now |
| RECOVERED_CURRENT | `x < r50` | RELAPSED | Record relapse |
| RELAPSED or RECOVERED_HISTORICAL | new `x ≤ B0′−D` with **recomputed** B0′ | PENDING | Refractory restart; prior episode closed; `refractory_polls=1` |

---

## HISTORICAL vs CURRENT (alignment note)

| Source | Definition | v0.3.4-draft |
|--------|------------|--------------|
| Claude harness `7a7c35f8` | “Historical = crossing observed before confirmation date” | **REJECTED as label rule** (would mislabel Case A) |
| Claude `3c271dfe` / Grok Case A | at confirm, if `x < r50` → HISTORICAL; if `x ≥ r50` → CURRENT | **ADOPTED** |
| Audit | `cross_preceded_confirm: bool` | Diagnostic only |

Case A: cross at 802, confirm at 804 with x≥r50 → **RECOVERED_CURRENT** (early cross does not force HISTORICAL).

---

## B1 estimand lock

Unchanged from v0.3.3 intent: preserve **all** confirmed episodes; crossing-anchored B1 = retrospective audit only; no delta_B; recognition-anchored = DECLARED_NOT_IMPLEMENTED.  
`CONFIRMED_UNRECOVERED` has no B1 anchor until `T_cross_obs` exists.

---

## Synthetic tests (executed)

Params primary: `B0=40`, `D=8`, `K=2`, `N=3`, `confirm_days=540`, `M=8`, `R_followup_max_polls=6`, `refractory_polls=1`, `trough_policy=revise_on_deeper_trough`.

**`all_pass` = True**

| Case | Intent | Result |
|------|--------|--------|
| `A_cross_then_confirm_current` | cross then confirm, current; aligns HISTORICAL/CURRENT vs Claude 7a7c35f8 | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
| `B_cross_then_relapse_historical` | cross then relapse before confirm → HISTORICAL by x_at_confirm < r50 | **PASS** final=SEEK_ONSET label=RECOVERED_HISTORICAL |
| `C_deeper_trough_K_of_next_3_does_not_confirm` | Case C: restore K-of-next-3; v0.3.3 silent append rejected | **PASS** final=SEEK_ONSET label=CENSORED |
| `C_contrast_unbounded_append_VARIANT_NOT_DEFAULT` | explicit contrast: unbounded append WOULD confirm at 805 — NOT the primary rule | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
| `D_same_poll_cross_and_confirm` | same-poll confirm/cross; onset at B0-D so immediate-next does not fire early | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
| `E_end_of_series_censored` | EOS before K — NOT a timeout test | **PASS** final=SEEK_ONSET label=CENSORED |
| `E2_confirm_window_timeout_540d` | 540d timeout ≠ EOS | **PASS** final=SEEK_ONSET label=CENSORED |
| `F_pending_tracks_cross_before_confirm` | PENDING tracks cross before confirm | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
| `G_confirm_first_recovery_later` | CONFIRMED_UNRECOVERED then recovery-later; not immediate CENSORED_NO_CROSS | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
| `H_confirmed_unrecovered_then_limit` | CENSORED_NO_CROSS only after follow-up limit, not at confirm | **PASS** final=SEEK_ONSET label=CENSORED_NO_CROSS |
| `I_refractory_restart_multi_episode` | refractory duration=1 poll; baseline STRICTLY_TRAILING_M recomputed; multi-episode | **PASS** final=SEEK_ONSET label=RECOVERED_CURRENT |
