Subject: [PATCH 01/31] feat(bench): digest-equal statePreserved +
 trialAccounting before N=1000

Tighten claim-path fleet measurement: exact step/result digest equality vs
per-trial no-crash twins (deterministic mock owner ids), explicit
trialAccounting denominators, and honest read/model-call limits in docs.

 ### 2. Every side effect through a journaled step
 
 Writes already do. **Reads, model calls, timers, sleeps, and waits for approval** must too, or recovery cannot reconstruct where the program was. Deadline board: timers survive restarts. Model calls need recording **or** an explicit “re-request on recovery” rule.

+**Reads (honest limit):** A completed read is journaled and **replayed** on resume (upstream is not hit again). An interrupted read with no journal entry is **re-requested once**. Resumption therefore assumes that re-read is acceptable — the upstream is repeatable, or the program tolerates a fresh value. If underlying data changed and a later step’s stored args no longer match the plan, recovery **hard-stops** (`journal_divergence`) rather than silently taking a divergent path. We do **not** yet claim that every mid-read crash reconstructs the exact pre-crash bytes without re-request.
+
+**Model calls (honest limit):** A completed `model_call` journals the host response and **replays** it. A crash mid-call with no entry **re-requests once**; the new response may differ from the lost one. Limit in one line: **at most one repeated model request per crash, never a repeated write.**

Subject: [PATCH 03/31] docs: fix N=1000 pass criteria before results; scope
 digest claim

Commit claim-path pass gates in durability STATUS before the lab run
lands; document that fleet digest equality uses a deterministic mock
while real APIs depend on journal replay; HOLD density climb until
swap/live-heap characterize the ~8GB@102.5k resident slope.

+| **Wait approval** | `columns.waitApproval.okRate === 1` | Separate arm; every await trial survives peer kill and completes after approve |
+| **Mid-flight honesty** | Mid-flight phases (`after_intent_before_call`, `during_call`) end `outcome_unknown` as expected; **not** required to `completedClean`; must appear in `trialAccounting` with `filteredOut === 0` | Expected unknown ≠ failure |
+| **Board ok** | Evidence `ok === true` (zero dups, zero deadline misses, every phase expectation met) | Includes mid-flight unknown expectations |

+
+Open from the density thread: a ClawQL resident reading on the order of **~8 GB @ ~102,500 agents** does **not** fit under the **512 MiB** fair-board cap at that slope (~80 KiB/agent). Before this board runs further climb / publish arms, check swap and live heap — RSS alone can hide page-cache, allocator headroom, or swap-backed anon.
+
+**Checked on this cloud-agent host (Thursday, Oct 29, 2026, America/Los_Angeles):**
+
+| Check | Result |
+| ----- | ------ |
+| **Swap** | **None configured** (`Swap: 0B`; `/proc/swaps` empty). RSS pressure cannot spill to disk — OOM/kill risk instead of silent swap bloat. |
+| **Live heap (published fair evidence)** | [`evidence-fair.json`](./evidence-fair.json) `clawqlRun`: at limit (past 2.5e6 schedule) `heapUsedKiB` **381210** (~372 MiB) vs `rssKiB` **550664** (~538 MiB) → heap/RSS ≈ **0.69**. After-GC slope `heapUsedKiBPerAgentAfterGc` **0.1504** vs total-RSS `residentKiBPerAgent` **0.2065**. |
+| **Current fair slope vs 512 MiB** | At **0.2065 KiB/agent**, ~2.5e6 agents fit near the cap (matches measured limit). At an **~80 KiB/agent** slope, **102,500 agents ≈ 8 GiB** and max under 512 MiB is only ~6.5k agents — that slope is **not** the typed-array deadline-schedule arm in evidence-fair; identify which arm produced it before climbing. |
+| **Balloon** | Hypervisor balloon present (`balloon_inflate − balloon_deflate`); `free` under-reports usable RAM — do not use `MemAvailable` alone to clear a density gate. |
+
+**Gate:** do not resume density climb or publish a new resident row until (1) the ~8 GB @ ~102.5k arm is identified (config + commit), (2) that arm reports `heapUsed` after GC alongside RSS, and (3) swap remains absent or is explicitly measured if enabled. Current paused writer-bound numbers stay valid as single-host lab; this HOLD is about not extending them.

 **Gate:** do not resume density climb or publish a new resident row until (1) the ~8 GB @ ~102.5k arm is identified (config + commit), (2) that arm reports `heapUsed` after GC alongside RSS, and (3) swap remains absent or is explicitly measured if enabled. Current paused writer-bound numbers stay valid as single-host lab; this HOLD is about not extending them.

 ### 2. Every side effect through a journaled step

Subject: [PATCH 05/31] fix(bench): bound fleet rebuild after self-fence; mark
 partial evidence

Survivor SELF-FENCE previously hung the N=1000 lab in unbounded ready waits.
Cap rebuild/restart attempts, catch twin/rebuild failures, and mark mid-run
evidence status=partial with ok=false until all arms finish.

Subject: [PATCH 06/31] docs+bench: N=1000 fail report; twin retry and reason
 classification

Classify outer misses as availability (deadline / pause fetch) not state
divergence; state miss is twin_capture_failed not digest_mismatch. Document
next-run options without loosening frozen criteria. Make twin capture
retry-safe and record per-trial reason for the next board.

+| Resume deadline        | **FAIL** ≥4 misses                      | Known celld availability: survivor `SELF-FENCE` (code 3) → rebuild inside resume clock; `resumeMs` can run to minutes (e.g. trial 132 ≈904s). Rate ~1% so far, in line with stock board **0.9%** deadline / **0.6%** fence — not a fluke. |
+| Completed (outer)      | **FAIL** ~183/185                       | **Both** outer incompletes are availability/harness, not divergent program state: (1) trial **132** `before_intent` — `resumeDeadlineMiss` after fence ~130; (2) trial **276** `before_intent` — `pause failed: fetch failed` after fence ~270. `after_call_before_journal` still **92/92** clean. |
+| State preserved        | **FAIL** rate &lt;1 (1 miss in eligible) | **Classified: `twin_capture_failed`, not digest mismatch.** Resumed journal was not shown to differ; the no-crash twin never completed (twin shares the same fleet — fences can kill the capture).

+
+**Do not just re-run the same board.** ~0.9% self-fence matches the published stock availability cost; with **zero deadline misses** as a gate, the same failure will recur on unchanged celld.
+
+**Next-run options (pick one before starting; write criteria first):**
+
+1. **Fix celld first (preferred if keeping zero-deadline).** Land pending celld availability work (bounded lease sweep, alive vs ready health, pause-aware clocks), then re-run **the same frozen criteria**. This fail stays published.
+2. **Split correctness vs availability (honest only if fixed in advance).** New board criteria, written before the run: correctness = zero dups, zero divergence, zero write reruns, outer completed 1.0, statePreserved digest rate 1.0 (with twin retry), await okRate 1.0; availability = report fence rate + deadline-miss rate with upper bound (as the published Tier C claim already does at 0.6% / 0.9%). Keep **this failed zero-deadline run** published next to it. Reasoning: mirrors existing claim structure; does not pretend availability is correctness.
+
+**Harness follow-ups already in flight for the next run (not a criteria change):** classify `statePreserved.reason` as `digest_match` \| `digest_mismatch` \| `twin_capture_failed`; make twin capture **retry-safe** (several attempts + rebuild) so a fence during twin does not look like a state mutation.
+
 ## Scoped Tier C claim (measured — stock R2)
 
 > Across 1,000 crashes injected at every phase of a write, programs resumed on another node with no repeated writes (the 95% upper bound on the duplicate rate is 0.3%). The median resume took about 12 seconds, set by the lease timeout. Writes caught mid-flight are marked outcome unknown for a person to resolve. Under stock settings, 0.6% of surviving nodes paused themselves for safety, and 0.9% of resumes missed the recovery deadline.

Subject: [PATCH 08/31] docs+bench: lock claim-path v2 correctness/availability
 criteria before re-run
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Option 2 chosen: split wrong outcomes (correctness, zero) from no-outcome-in-time
(availability, ≤2% ceiling + resume p99/max). Criteria dated before the next board.
Harness FLEET_PHASED_SCORE_MODE=correctness_availability_v2; v1 zero-deadline fail
stays published. Celld availability fixes remain parallel, not blocking.

+**Do not just re-run the same board under the zero-deadline criteria.** ~0.9% self-fence matches the published stock availability cost; that gate will fail again on unchanged celld. **Chosen path (locked Friday, Oct 30, 2026 before the next run starts):** option 2 — split correctness vs availability. Celld availability fixes proceed **in parallel** (not a blocker); when they land, a later re-measure can show deadline-miss rate falling from X% to Y%.
 
-**Next-run options (pick one before starting; write criteria first):**
+### N≈1000 claim-path pass criteria v2 — correctness / availability split (fixed before re-run — Friday, Oct 30, 2026)
 
-1. **Fix celld first (preferred if keeping zero-deadline).** Land pending celld availability work (bounded lease sweep, alive vs ready health, pause-aware clocks), then re-run **the same frozen criteria**. This fail stays published.
-2. **Split correctness vs availability (honest only if fixed in advance).** New board criteria, written before the run: correctness = zero dups, zero divergence, zero write reruns, outer completed 1.0, statePreserved digest rate 1.0 (with twin retry), await okRate 1.0; availability = report fence rate + deadline-miss rate with upper bound (as the published Tier C claim already does at 0.6% / 0.9%). Keep **this failed zero-deadline run** published next to it. Reasoning: mirrors existing claim structure; does not pretend availability is correctness.
+**Why the criteria changed (stated before the new run):** The v1 board required zero resume deadline misses. That mixes **wrong outcomes** (correctness) with **no outcome in time** (availability). The published Tier C claim already discloses availability as a rate (0.6% self-fence / 0.9% deadline miss). v2 matches that structure. **v1 evidence stays published** at [`phased-n1000-claim-path.json`](../program-cell-fleet-kill/phased-n1000-claim-path.json) as a failed zero-deadline board; v2 evidence target: [`phased-n1000-correctness-availability.json`](../program-cell-fleet-kill/phased-n1000-correctness-availability.json). Harness: `FLEET_PHASED_SCORE_MODE=correctness_availability_v2`.
 
-**Harness follow-ups already in flight for the next run (not a criteria change):** classify `statePreserved.reason` as `digest_match` \| `digest_mismatch` \| `twin_capture_failed`; make twin capture **retry-safe** (several attempts + rebuild) so a fence during twin does not look like a state mutation.
+**Definitions (outcome, not column):**
+
+| Class | Meaning | Counts as |
+| ----- | ------- | --------- |
+| **Correctness failure** | A **wrong** outcome | duplicate write; `journal_divergence`; write-step rerun; **digest mismatch** (`statePreserved.reason === digest_mismatch`) |
+| **Availability failure** | **No** outcome in time / capture | resume deadline miss; pause failure (`pause failed: …`); **twin_capture_failed**; await arm that does not survive+complete without a wrong write |
+| **Outer completion** | Reported overall | Each outer miss is assigned to correctness **or** availability above — not a third zero-gate |
+
+**Pass gates (frozen for v2 — do not loosen after results):**
+
+| Gate | Pass iff | Note |
+| ---- | -------- | ---- |
+| **Correctness** | `gates.correctness.failures === 0` | Zero wrong outcomes across write-kill + await |
+| **Availability ceiling** | `gates.availability.failureRate ≤ 0.02` (2%) | Denominator = all write-kill + await trials (`overallN`). Consistent with published ~1.5%-class disclosure band |
+| **Availability tail** | Evidence reports `resumeMs.p99`, `resumeMs.max`, and `recoveryMs.p99` | A 904s resume must stay visible — not absorbed into a single miss count |
+| **Outer completion** | Reported with per-miss class | Informational for the claim; misses classified, not required to be 0 if they are availability |
+| **Wait approval** | Wrong-write → correctness; no survive/complete in time → availability | Same split |
+| **Board ok** | Correctness zero **and** availability ≤ 2% | `status=measured` only when both arms finish |
+
+**Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest), with **availability disclosed** (fence + deadline + pause/twin-capture rates, ceiling 2%, resume p99/max). Still not mid-step unmodified agents. Celld lease-sweep / alive-vs-ready / pause-aware clocks remain parallel product work.

Subject: [PATCH 10/31] bench: parallel availability hardenings for claim-path
 v2

Fresh CELLD_NODE + port settle on restart; twin prefer ensureSurvivor
over rebuild storms; v2 gates report recoveryMs p99/max; document
lease-sweep / alive-vs-ready / pause-aware tracks as parallel product
work that does not block the correctness/availability board.

+| **Lease-sweep** | Retire dead node-session leases so a restarted peer is not blocked by a fenced identity | Upstream (`dead_node_gc`); harness mitigates with fresh `CELLD_NODE` per start |
+| **Alive vs ready** | `/health` can answer while `ready_gate` is still closed — callers must wait `/program/health` (or ready_gate), not confuse alive with serving | Harness already probes `/program/health?cell=health`; product docs / SDK should match |

Subject: [PATCH 11/31] bench: pause-aware resume deadline during orchestrator
 recovery

Freeze the resume deadline clock while ensureSurvivor/rebuild runs
(FLEET_PHASED_PAUSE_AWARE_DEADLINE default on). Wall resumeMs still
includes recovery so multi-minute stalls stay visible; evidence also
records resumeActiveMs. Completes the in-repo half of the parallel
celld triad from option-2 (lease-sweep/alive-vs-ready remain upstream).

 **Do not just re-run the same board under the zero-deadline criteria.** ~0.9% self-fence matches the published stock availability cost; that gate will fail again on unchanged celld. **Chosen path (locked Friday, Oct 30, 2026 before the next run starts):** option 2 — split correctness vs availability. Celld availability fixes proceed **in parallel** (not a blocker); when they land, a later re-measure can show deadline-miss rate falling from X% to Y%.

 ## Stall forensics (stock 10s / R2)
 

From 25d0134b427c88922cf150a0bb47ac1ba19c86bf Mon Sep 17 00:00:00 2001

Subject: [PATCH 13/31] fix(bench): score availability on wall-clock resume,
 not frozen deadline
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reverts the ensureSurvivor/rebuild deadline freeze — a multi-minute
orchestrator stall is still a miss from the user's point of view.
resumeActiveMs/recoveryMs remain diagnostic only (no pass/fail ceiling).
Clarify pause-aware clocks as host pause/suspend (still open on celld).

 **Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest), with **availability disclosed** (fence + deadline + pause/twin-capture rates ≤2%; resume/recovery p99/max reported, no separate tail ceiling). Still not mid-step unmodified agents. Parallel celld product work (not a v2 gate): lease renew / lease-sweep / alive-vs-ready / **pause-aware clocks** (host pause/suspend — wall time jumps while the machine was not running; distinct from orchestrator recovery). Do **not** freeze the resume deadline during `ensureSurvivor`/rebuild — that would quietly loosen the availability criterion.

 **Why the criteria changed (stated before the new run):** The v1 board required zero resume deadline misses. That mixes **wrong outcomes** (correctness) with **no outcome in time** (availability). The published Tier C claim already discloses availability as a rate (0.6% self-fence / 0.9% deadline miss). v2 matches that structure. **v1 evidence stays published** at [`phased-n1000-claim-path.json`](../program-cell-fleet-kill/phased-n1000-claim-path.json) as a failed zero-deadline board; v2 evidence target: [`phased-n1000-correctness-availability.json`](../program-cell-fleet-kill/phased-n1000-correctness-availability.json). Harness: `FLEET_PHASED_SCORE_MODE=correctness_availability_v2`.

+| **Availability denominator** | **All 1000 trials** = 750 write-kill + 250 await | `gates.availability.denominator === overallN === 1000`. Every await trial is one unit in the denominator. Numerator = availability-class failures from **either** arm (deadline miss, pause fail, twin_capture_failed, await not survive/complete).

Echo locked deadline, 2% ceiling, and 1000-trial denominator into the
evidence JSON so post-hoc loosening is visible against the run file.

 **Sampling honesty (not a criteria change):** With a true availability-miss rate near the published ~1.5%, a 1000-trial binomial draw sits above 2% by chance roughly **1 time in 12**. If that happens, it is an **honest fail** like v1 — fix celld / re-measure; do **not** loosen the ceiling or the 60 s deadline after seeing results.

-**Do not just re-run the same board under the zero-deadline criteria.** ~0.9% self-fence matches the published stock availability cost; that gate will fail again on unchanged celld. **Chosen path (locked Friday, Oct 30, 2026 before the next run starts):** option 2 — split correctness vs availability. Celld availability fixes proceed **in parallel** (not a blocker); when they land, a later re-measure can show deadline-miss rate falling from X% to Y%.

Denominators: see trialAccounting — no trials filtered; outer-only rates exclude mid-flight kills that intentionally end outcome_unknown. Completed reads are journaled and replayed; an interrupted read with no entry is re-requested once (resumption assumes that re-read is acceptable).

 **Kept published** as the failed zero-deadline board next to v2. **Chosen path (locked Friday, Oct 30, 2026 before the next run):** option 2 — split correctness vs availability (see below). Celld fixes proceed in parallel; a later re-measure can show deadline-miss rate falling from X% to Y%.

Subject: [PATCH 20/31] docs+bench: explain v1 await 70/250; fix park-fail
 harness before v2 await
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v1 ran all 250 await trials (70 ok); 178 were silent park_failed continues
with no failureClass/log/rebuild — not an incomplete arm and not correctness.
Classify+log+rebuildFleet on park fail; keep await failureByReason in evidence.
STATUS fail report + awaitArmForensics updated; v2 restarted on fixed harness
(same frozen criteria, fresh R2 prefix).

+#### Wait approval 70/250 — what the 180 failures were
+
+`okRate=0.28` is **not** an incomplete arm and **not** mostly correctness. The await loop ran all **250** trials (`status=measured`, `awaitTrialsCompleted=250`). Log output stopped at `await 74/250` then printed `done` because the **park-fail path** pushed `ok=false` and `continue`d **without `console.log`** — trials 75–250 left no log lines.
+
+| Class | Count | Notes |
+| ----- | ----- | ----- |
+| **ok** | **70** | Survived peer kill + completed after approve |
+| **Availability — `await_park_failed`** | **178** | `/program/run` never parked (`fetch failed` / node down). Includes silent trials 27–28 and **75–250** |
+| **Availability — not survived / deadline** | **2** | Logged: await 26 (`resumeMs≈909s`), await 74 |
+| **Correctness (dup / wrong write)** | **0** | No `writeCount>1` in the retained sample |
+
+Evidence field: `awaitArmForensics` on [`phased-n1000-claim-path.json`](../program-cell-fleet-kill/phased-n1000-claim-path.json).
+
+**Harness bugs (fixed before v2 await; criteria unchanged):** (1) park-fail lacked `failureClass` — under v2 scoring those 178 would have been **invisible** to the availability gate; (2) no log line; (3) no fleet rebuild, so one dead node burned the rest of the arm; (4) evidence kept only the first 50 await trials, hiding the park-fail tail. Fix in `run-board.mjs`: classify + log + `rebuildFleet` on park fail; keep all await failures + `failureByReason`. **v2 board restarted** so the running process loads the fixed harness (write-kill progress discarded; same frozen v2 criteria, fresh R2 prefix).
+
 **Kept published** as the failed zero-deadline board next to v2. **Chosen path (locked Friday, Oct 30, 2026 before the next run):** option 2 — split correctness vs availability (see below). Celld fixes proceed in parallel; a later re-measure can show deadline-miss rate falling from X% to Y%.

 #### Wait approval 70/250 — what the 180 failures were
 
 `okRate=0.28` is **not** an incomplete arm and **not** mostly correctness. The await loop ran all **250** trials (`status=measured`, `awaitTrialsCompleted=250`). Log output stopped at `await 74/250` then printed `done` because the **park-fail path** pushed `ok=false` and `continue`d **without `console.log`** — trials 75–250 left no log lines.

-| **Availability — `await_park_failed`** | **178** | `/program/run` never parked (`fetch failed` / node down). Includes silent trials 27–28 and **75–250** |
-| **Availability — not survived / deadline** | **2** | Logged: await 26 (`resumeMs≈909s`), await 74 |

Grep for 900/15min across celld+harness did not find a lease/R2 15-minute
timeout. The cluster (~875–909s) matches programAttempts=180 × fetchJson
timeout 5s when /health accepts but does not respond. waitUrl/waitNode now
use wallMs + 1.5s polls; resume-path ensureSurvivor respects deadlineAt.
Criteria unchanged; running v2 process unaffected until next start.

+
+Three stalls clustered at **~875–909s** (~15 min) across different surface causes. Grep for `900` / `900000` / `15 * 60` did **not** find a celld lease TTL or R2 client default at 15 minutes. What matched:
+
+| Candidate | Finding |
+| --------- | ------- |
+| **Harness `waitNode` (hit)** | Comment said `programAttempts=180` ≈ 45s (180×250ms sleep). Each try used `fetchJson` **timeoutMs=5000**. When `/health` **accepts TCP but never responds**, every attempt burns the full 5s → **180×5s = 900s**. Observed `/health` hang on a live fleet node while `/program/health` still answered. |
+| **Deadline bypass** | `ensureSurvivor` → `waitNode` ran **inside** the resume clock without a wall/deadline cap, so a single recovery could outrun `FLEET_PHASED_RESUME_DEADLINE_MS=60000` and leave `resumeMs≈900s` with `recoveryMs=0` when wait eventually succeeded. |
+| **celld knobs checked** | `CELLD_TTL_MS=10000`; `CELLD_READY_FLEET_GATE_MS` default **120000** (2 min); `CELLD_OPERATION_DEADLINE_MS` default **15000**; `CELLD_LTX_DURABILITY_TIMEOUT_SECS` default **10** (queued write ≤ six budgets). Binary contains one `900000` (ms) literal — not wired to an documented env default we could name. |
+| **Host pause** | Still possible for some tails (pause-aware clocks remain open); does not explain the exact attempt×timeout arithmetic. |
+
+**Harness fix (criteria unchanged; takes effect on the next board process):** `waitUrl`/`waitNode` take a **wallMs** budget (default 45s program / 30s health) and shorter per-try timeouts (1.5s); resume-path `ensureSurvivor` gets `deadlineAt = resumeStart + RESUME_DEADLINE_MS` and always attributes wait time to `recoveryMs`. Does not change the frozen 60s availability deadline or 2% ceiling.

Subject: [PATCH 24/31] docs+bench: v2 interim failure breakdown; twin_capture
 forces !ok
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Document 15 availability fails at ~500 write-kill (5×~900s deadline,
4 pause cascade, 5 no_expected, 1 twin). p99 spike is the discrete
900s class (p95 still ~14s), not rising typical recovery. Treat board
as likely avail fail; finish for correctness. Twin capture now clears
expectOk so trialFailures includes it.

 **Sampling honesty (not a criteria change):** With a true availability-miss rate near the published ~1.5%, a 1000-trial binomial draw sits above 2% by chance roughly **1 time in 12**. If that happens, it is an **honest fail** like v1 — fix celld / re-measure; do **not** loosen the ceiling or the 60 s deadline after seeing results.

+Snapshot ~500/750 write-kill (await not started). **Correctness failures = 0.** Availability **15 / 500 (3.0%)** — already on course to miss the frozen 2% ceiling of 20/1000 unless the remaining 500 trials (incl. await) fail at ~⅓ the current rate. **Let the board finish** for full correctness evidence across write-kill + await; stop early only if failures reach 21 (certain fail). If availability ends above 2%, report an **honest fail**: zero correctness failures measured; availability X% above the pre-locked ceiling; celld / harness fixes next — do **not** call the board a pass.

+**Availability failure classes (15 at ~500 trials):**
+
+| Class | Count | Notes |
+| ----- | ----- | ----- |
+| `resume_deadline_miss` | **5** | All ~870–921s; `recoveryMs=0`, `resumeStatus=0` (resume loop never entered) |

+| `twin_capture_failed` | **1** | Trial 335; fleet shared with twin |
+
+**~900s / p99:** Not a rising typical recovery. Evidence **p95 ≈ 14s**; **p99 ≈ 870s** because **5/500 (1%)** trials are the discrete ~900s class — so p99 lands inside that class. Each ~900s miss is usually followed by 1–3 cascade fails (pause / no_expected). Root cause: harness `waitNode` **180 × 5s fetch timeout** when `/health` accepts but does not respond (not a celld 15-minute lease). Wall-cap fix is on the branch; **this v2 process still runs the pre-fix script** — stalls can continue until the next board start.
+
 **Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest), with **availability disclosed** (fence + deadline + pause/twin-capture rates ≤2% of 1000; resume/recovery p99/max reported, no separate tail ceiling). Still not mid-step unmodified agents. Parallel celld product work (not a v2 gate): lease renew / lease-sweep / alive-vs-ready / **pause-aware clocks** (host pause/suspend — wall time jumps while the machine was not running; distinct from orchestrator recovery). Do **not** freeze the resume deadline during `ensureSurvivor`/rebuild — that would quietly loosen the availability criterion.

Subject: [PATCH 26/31] docs+bench: cluster avail fails; settle during_call
 404; label two fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Harness wait-cap only speeds failure classification — celld hang (/health
accepts, never ready) is the real incident (lease-sweep / alive-vs-ready).
Report 15 fails as ~5 stall clusters. during_call 404×5: writeCount=0, no
divergence, 4/5 in cascades — not proven lost committed state; correctness
stays 0. Next harness retries mid-flight 404 until wall deadline and stores
programId for later status checks.

 Snapshot ~500/750 write-kill (await not started). **Correctness failures = 0.** Availability **15 / 500 (3.0%)** — already on course to miss the frozen 2% ceiling of 20/1000 unless the remaining 500 trials (incl. await) fail at ~⅓ the current rate. **Let the board finish** for full correctness evidence across write-kill + await; stop early only if failures reach 21 (certain fail). If availability ends above 2%, report an **honest fail**: zero correctness failures measured; availability X% above the pre-locked ceiling; celld / harness fixes next — do **not** call the board a pass.
 
-**Availability failure classes (15 at ~500 trials):**
+**Report as clusters (trials are not independent):** **15 classified failures ≈ 5 stall-seeded incidents** (covering 13 fails) **+ 1 twin + 1 lone `during_call` 404**. Fixing the underlying `/health` hang addresses most failures at once.

-**~900s / p99:** Not a rising typical recovery. Evidence **p95 ≈ 14s**; **p99 ≈ 870s** because **5/500 (1%)** trials are the discrete ~900s class — so p99 lands inside that class. Each ~900s miss is usually followed by 1–3 cascade fails (pause / no_expected). Root cause: harness `waitNode` **180 × 5s fetch timeout** when `/health` accepts but does not respond (not a celld 15-minute lease). Wall-cap fix is on the branch; **this v2 process still runs the pre-fix script** — stalls can continue until the next board start.
+**Per-class counts (same 15):** deadline miss ×5 · pause_failed ×4 · no_expected_outcome ×5 · twin ×1.
+
+**Two fixes — label what each does:**
+
+| Fix | Layer | What it does | What it does *not* do |
+| --- | ----- | ------------ | --------------------- |
+| Cap `waitNode` wall time / resume `deadlineAt` | **Harness** | Turns a 15-minute harness wait into a **faster classified failure** (p99 optics) | Does **not** make `/health` answer; availability may improve less than the tail suggests |
+| Bounded lease-sweep + alive vs ready | **celld (product)** | Stops the **node hang** where `/health` accepts TCP but never responds (same pattern as the dead-leader-sweep spiral) | Still on the parallel celld list — this is the real availability fix |
+
+**`during_call` 404 ×5 — settled for correctness (not lost committed state):**
+
+All five (`134`, `286`, `390`, `442`, `494`): `phase=during_call`, `writeCount=0`, `writesBefore=0`, `duplicates=0`, `resumeError=not_found`, no `journalDivergence`. Code path journals **write intent + meta** before the hanging upstream call; pets `inFlight>0` before SIGKILL; **no outside write landed**. Four of five sit in stall cascades (fleet already wedged). Harness treats the **first** resume `404` as terminal (does not keep waiting for visibility). So: **no evidence of a lost committed write or wrong outcome** under frozen correctness definitions → correctness stays **0**. Residual: a 404 means meta was invisible on the survivor at query time — **not proven permanently deleted** vs routing/visibility; next harness should retry mid-flight 404 until the wall deadline and retain `programId` for later `/status` checks before ever promoting this class to correctness.
 
 **Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest), with **availability disclosed** (fence + deadline + pause/twin-capture rates ≤2% of 1000; resume/recovery p99/max reported, no separate tail ceiling). Still not mid-step unmodified agents. Parallel celld product work (not a v2 gate): lease renew / lease-sweep / alive-vs-ready / **pause-aware clocks** (host pause/suspend — wall time jumps while the machine was not running; distinct from orchestrator recovery). Do **not** freeze the resume deadline during `ensureSurvivor`/rebuild — that would quietly loosen the availability criterion.

-| **Harness `waitNode` (hit)** | Comment said `programAttempts=180` ≈ 45s (180×250ms sleep). Each try used `fetchJson` **timeoutMs=5000**. When `/health` **accepts TCP but never responds**, every attempt burns the full 5s → **180×5s = 900s**. Observed `/health` hang on a live fleet node while `/program/health` still answered.            |
-| **Deadline bypass**          | `ensureSurvivor` → `waitNode` ran **inside** the resume clock without a wall/deadline cap, so a single recovery could outrun `FLEET_PHASED_RESUME_DEADLINE_MS=60000` and leave `resumeMs≈900s` with `recoveryMs=0` when wait eventually succeeded.                                                                |

Binary contains one `900000` (ms) literal — not wired to an documented env default we could name. |
-| **Host pause**               | Still possible for some tails (pause-aware clocks remain open); does not explain the exact attempt×timeout arithmetic.                                                                                                                                                                                            |
+| Layer | Finding | Fix does |
+| ----- | ------- | -------- |
+| **Harness (explains the 15 minutes)** | `waitNode` used `programAttempts=180` × `fetchJson` **5s** when `/health` accepts TCP but never responds → **180×5s=900s**. Also bypassed the 60s resume deadline. | **Wall-cap + `deadlineAt`** → faster **classified failure**, better p99 optics. Does **not** make the node healthy. |
+| **celld (explains why `/health` hung)** | Same pattern as the N=1000 dead-leader-sweep spiral: process accepts connections, does not become ready. | **Bounded lease-sweep** + **alive vs ready** (still on the parallel product list). This is what removes the *incident*, not just the wait. |
 
-**Harness fix (criteria unchanged; takes effect on the next board process):** `waitUrl`/`waitNode` take a **wallMs** budget (default 45s program / 30s health) and shorter per-try timeouts (1.5s); resume-path `ensureSurvivor` gets `deadlineAt = resumeStart + RESUME_DEADLINE_MS` and always attributes wait time to `recoveryMs`. Does not change the frozen 60s availability deadline or 2% ceiling.
+**v2 mid-run (~500 write-kill):** five ~900s stalls seed cascades; **15 failures ≈ 5 stall incidents + twin + 1 lone mid-flight 404**. **p95≈14s / p99≈870s** = discrete stall class (1% of trials), not rising typical recovery. Running v2 process still has the pre-wall-cap harness.
 
-**v2 mid-run confirmation (~500 write-kill):** five stalls at 875626 / 908491 / 902307 / 870413 / 920802 ms — all `resumeStatus=0`, `recoveryMs=0`, no self-fence. **p95≈14s, p99≈870s**: the p99 rise is those discrete stalls (5/500 = 1%), not a steady climb of typical recovery. Each stall usually seeds a short cascade (`pause_failed` / `no_expected_outcome` on the next 1–3 trials) via `DurableObjectRoutingError` / fetch failed while the fleet is wedged. The running v2 Node process still has the pre-wall-cap harness; expect more ~900s events until this board exits and a new process loads the fix.
+**`during_call` resume 404 (correctness check):** intent+meta are journaled before the hanging upstream call; all five no_expected trials had **writeCount=0** (no committed outside write) and no journal divergence. Four sit in stall cascades. Harness stops on first 404, so visibility lag vs permanent meta loss is not separable from this evidence — **not reclassified as correctness**; residual noted for harness retry-on-404 + retain `programId`.

Subject: [PATCH 28/31] docs: R2 settle during_call 404s as durability
 (correctness non-zero)

Read-only check on the live v2 prefix shows trials 134/286/390/442 never
landed meta+intent in DO storage; 494 has create meta only without a
durable write intent. Do not publish correctness=0 for this board.

 ### N≈1000 v2 — interim (write-kill in progress; do not stop early)
 
-Snapshot ~500/750 write-kill (await not started). **Correctness failures = 0.** Availability **15 / 500 (3.0%)** — already on course to miss the frozen 2% ceiling of 20/1000 unless the remaining 500 trials (incl. await) fail at ~⅓ the current rate. **Let the board finish** for full correctness evidence across write-kill + await; stop early only if failures reach 21 (certain fail). If availability ends above 2%, report an **honest fail**: zero correctness failures measured; availability X% above the pre-locked ceiling; celld / harness fixes next — do **not** call the board a pass.
+Snapshot ~620/750 write-kill (await not started). Harness still reports **correctness failures = 0** / availability **15** — but the read-only R2 settle below **reclassifies the five `during_call` 404s as durability/correctness**, so this board must **not** be published with correctness = 0. Availability alone was already on course to miss the frozen 2% ceiling of 20/1000. **Let the board finish** for full write-kill + await evidence; stop early only if harness availability failures reach 21 (certain avail fail). Honest closeout: non-zero correctness (lost mid-flight journal) **and** availability above ceiling unless the tail is improbably clean — celld / harness fixes next; do **not** call the board a pass.
 
 **Report as clusters (trials are not independent):** **15 classified failures ≈ 5 stall-seeded incidents** (covering 13 fails) **+ 1 twin + 1 lone `during_call` 404**. Fixing the underlying `/health` hang addresses most failures at once.

+
+Harness still scored these as `failureClass=availability` (`no_expected_outcome` / first-404 terminal; running process predates mid-flight 404 retry). **Do not publish correctness = 0** for this board: four programs’ pretends-journaled state are absent from R2-backed DO storage, and 494 never got a durable write intent. That also fails the state-preserved reading of “journaled mid-flight state survives.” Outside writes still `writeCount=0` / no duplicates — the wrongness is **lost journal**, not a repeated write.
 
-All five (`134`, `286`, `390`, `442`, `494`): `phase=during_call`, `writeCount=0`, `writesBefore=0`, `duplicates=0`, `resumeError=not_found`, no `journalDivergence`. Code path journals **write intent + meta** before the hanging upstream call; pets `inFlight>0` before SIGKILL; **no outside write landed**. Four of five sit in stall cascades (fleet already wedged). Harness treats the **first** resume `404` as terminal (does not keep waiting for visibility). So: **no evidence of a lost committed write or wrong outcome** under frozen correctness definitions → correctness stays **0**. Residual: a 404 means meta was invisible on the survivor at query time — **not proven permanently deleted** vs routing/visibility; next harness should retry mid-flight 404 until the wall deadline and retain `programId` for later `/status` checks before ever promoting this class to correctness.
+**Next harness (either way):** retry mid-flight 404s until the wall deadline; retain `programId`; later `/status` check. Product path remains lease-sweep + alive-vs-ready so the wedged `/health` stall stops seeding these gaps.
 
-**Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest), with **availability disclosed** (fence + deadline + pause/twin-capture rates ≤2% of 1000; resume/recovery p99/max reported, no separate tail ceiling). Still not mid-step unmodified agents. Parallel celld product work (not a v2 gate): lease renew / lease-sweep / alive-vs-ready / **pause-aware clocks** (host pause/suspend — wall time jumps while the machine was not running; distinct from orchestrator recovery). Do **not** freeze the resume deadline during `ensureSurvivor`/rebuild — that would quietly loosen the availability criterion.

+Neighbor successful `during_call` programs (e.g. 130, 490) retain `pauseKind=during_call` and post-resume entries — the shape expected after journal-before-hang.
+
+## Verdict
+
+- **134, 286, 390, 442:** journaled intent **and** meta for this run are **absent** from R2-backed DO storage. Not a visibility-timeout 404 — durable state was never present (or was lost before any generation snapshot). → **durability / correctness** (not availability-only).
+- **494:** create meta survived; the `during_call` intent + `pauseKind` meta update **never** became durable. Resume-time 404 can still be availability/visibility, but the mid-flight journal contract was not met in storage. → **durability / correctness** for intent; do **not** publish correctness=0 on the strength of “404 alone.”
+
+Prior-run keys for indices 286/390/442/494 (different `Date.now()` suffixes, full meta+intent+entries) exist in older local gens and are **out of** the current-run timestamp windows — ignored for this settle.
+
+## Harness follow-up (unchanged)
+
+Retry mid-flight 404 until wall deadline; retain `programId`; later `/status` check. That remains the right permanent harness fix either way.

 Harness still scored these as `failureClass=availability` (`no_expected_outcome` / first-404 terminal; running process predates mid-flight 404 retry). **Do not publish correctness = 0** for this board: four programs’ pretends-journaled state are absent from R2-backed DO storage, and 494 never got a durable write intent. That also fails the state-preserved reading of “journaled mid-flight state survives.” Outside writes still `writeCount=0` / no duplicates — the wrongness is **lost journal**, not a repeated write.

Board finished under frozen criteria: availability 34/1000 (3.4%) above 2%
ceiling; harness correctness 0 predates mid-flight storage check; R2 settle
keeps correctness non-zero (five during_call lost-intent). Evidence JSON
committed; v1 fail remains published. Mechanism claim stays paused pending
output-gate/epoch-fence fork (PR #1453).

 Harness still scored these as `failureClass=availability` (`no_expected_outcome` / first-404 terminal; running process predates mid-flight 404 retry). **Do not publish correctness = 0** for this board: four programs’ pretends-journaled state are absent from R2-backed DO storage, and 494 never got a durable write intent. That also fails the state-preserved reading of “journaled mid-flight state survives.” Outside writes still `writeCount=0` / no duplicates — the wrongness is **lost journal**, not a repeated write.
 
 **Next harness (either way):** retry mid-flight 404s until the wall deadline; retain `programId`; later `/status` check. Product path remains lease-sweep + alive-vs-ready so the wedged `/health` stall stops seeding these gaps.
 
+**Mechanism claim impact (beyond this board):** the write protocol’s public fact “intent is journaled before the call” is **not reliably true on celld/R2** under these kills — the call can be in flight while intent is absent from durable storage. Zero duplicates here only because the mock upstream hung. A completing upstream would be a lost-order / possible double-charge on resume (`decideCallResume` → `rerun` when intent+`pauseKind` are both missing). **Publish readiness qualified** ([publish-readiness.md](../../gtm/publish-readiness.md)); Cost Plus / social correction: [cost-plus-thread-correction.md](../../gtm/cost-plus-thread-correction.md).
+
+**Root cause (celld already has an output gate — it failed under kill):** denoland/celld `crates/logic/output_gate.rs` holds `Channel::Fetch` until LTX proves a write position under the resident lease epoch (`CELLD_OUTPUT_GATE` default on; `=0` disables). Settled gaps still happened → either proof/ownership race, stale writer accepted into a discarded generation (bucket “cannot refuse a stale writer”), or local SQLite `synchronous=NORMAL` position ahead of what survivors can restore. **One fix closes both holes:** fenced acknowledgment — every storage write returns a sequence; egress held until durable **under the current lease epoch**; incarnation in lease + every write; R2 conditional reject of stale incarnation; refuse start if a live incarnation already holds the node ID. Spec: [celld-output-gate-epoch-fence.md](../../streams/celld-output-gate-epoch-fence.md). Local `storage.get` after `put` is **not** part of the fix (sanity only).
+
+**Conformance / next board:** TLA+ `IntentDurablyAckedBeforeSend`; trace checker; kill-after-fetch regression (**expected fail** until gate proven — then `CLAWQL_REQUIRE_OUTPUT_GATE=1`). v3: same frozen criteria + automatic mid-flight R2 intent check in the harness; restore mechanism claim only after correctness passes with that check. Parallel: lease-sweep + alive-vs-ready for the `/health` hang.
+
 **Claim if v2 clean:** step-level checkpointed durable execution on **correctness** (never a wrong write / digest **and** no lost pretends-journaled mid-flight meta/intent), with **availability disclosed** (fence + deadline + pause/twin-capture rates ≤2% of 1000; resume/recovery p99/max reported, no separate tail ceiling). Still not mid-step unmodified agents. Parallel celld product work (not a v2 gate): lease renew / lease-sweep / alive-vs-ready / **pause-aware clocks** (host pause/suspend — wall time jumps while the machine was not running; distinct from orchestrator recovery). Do **not** freeze the resume deadline during `ensureSurvivor`/rebuild — that would quietly loosen the availability criterion.

+# Cost Plus / X thread — correction (post now)
+
+**Status:** mechanism claim paused until v3 proves durable-ack-before-send.  
+**Action for human:** if the Cost Plus (or related durability) X thread already posted the “won’t double-charge” bullet, edit within the window or reply with the text below. If not posted yet, **drop that bullet**.
+
+## Do not post / remove
+
+- Interrupted orders are never blindly retried, so a crash won’t double-charge.
+- Write intent is always saved before the call goes out (as an absolute).
+
+## Safe reply / edit (copy-paste)
+
+> Correction: we found a gap in our celld/R2 path where a mid-flight kill can leave the upstream call in flight without a durable write intent on storage. In that case resume can re-run the write — so “crash won’t double-charge” is **not** a claim we can make until the output-gate / lease-epoch fix is proven on a fresh board. The published zero-duplicate measurement still stands as a measurement; the mechanism sentence is paused. We’re treating this as a top priority and will restore the claim only after a corrected board with an automatic storage check passes.
+
+## Website / video
+
+- Live benchmarks honesty copy updated in `apps/www/src/lib/durability-benchmarks.ts` (outcome-unknown vs lost-intent).
+- No in-repo durability explainer `VIDEO_SCRIPT` claimed intent-before-call; if an external video says intent is saved before the call, **stop promoting it** until re-rendered after v3.

+# Durable-ack latency (price of the guarantee)
+
+Every consequential outbound call waits for a durable commit under the current lease epoch before send (`CELLD_OUTPUT_GATE` + ClawQL `CELLD_FENCED_ACK` confirm GET).
+
+## What to publish
+
+| Metric | Source |
+| ------ | ------ |
+| p50 / p99 gate wait | celld `timing` / `durable_wait` spans (`wait_us`) |
+| Board overlay | fleet harness: time from intent put → fetch start |
+
+## How to measure (local / board)
+
+```sh
+# Single-node R2: fenced ack forces confirm GET after each LTX PUT
+CELLD_OUTPUT_GATE=1 CELLD_FENCED_ACK=1 \
+  RUST_LOG=timing=debug \
+  celld --bucket "$CELLD_BUCKET" --endpoint "$S3_ENDPOINT" ...
+# Collect wait_us from durable_wait events; report p50/p99 next to the claim.
+```
+
+Until a measured table lands beside a green v3 board, treat latency as **TBD** — do not invent numbers. The honest price of the guarantee is whatever those percentiles are after the forked binary is pinned.

+**Upstream:** [denoland/celld](https://github.com/denoland/celld) (Apache-2.0) `v0.4.0`.  
+**ClawQL fork:** lands on [`cursor/output-gate-epoch-fence-2725`](https://github.com/danielsmithdevelopment/ClawQL/pull/1453) as `vendor/celld` (binary `0.4.0-clawql.1`) until a standalone fork repo exists.
+
+## What already exists in celld v0.4.0
+
+| Piece | Location | Behavior |
+| ----- | -------- | -------- |
+| Output gate | `crates/logic/output_gate.rs` | Every egress `Channel` (including `Fetch`) held until write position is proven durable under the **resident epoch** |
+| Disable | `CELLD_OUTPUT_GATE=0` | Shell skips `Event::Output` — **never set this on fleet boards** |
+| Fetch path | `crates/celld/js.rs` `op_fetch` → `await_egress_gate` | “Whatever this request can reveal must be durable before it leaves” |
+| Bucket proof + ownership | `durable_reached` → `VerifyOwnership` | Bucket proof alone is not enough; ownership must still name this node at this epoch |
+| Known gap (upstream comment) | same | “the bucket cannot refuse a stale writer” |
+
+Despite the gate, ClawQL N=1000 settle found mid-flight hangs with **no durable intent** on R2/DO storage (and 494 with create meta only). So either the gate released on a proof survivors cannot restore, a stale incarnation wrote a discarded generation, or local `synchronous=NORMAL` position advanced ahead of true LTX durability.
+
+## One fix (closes H1 + H2) — landed in ClawQL fork (PR #1453)
+
+1. **Fenced acknowledgment (`CELLD_FENCED_ACK`, default on)**  
+   - Every storage write returns a **sequence / position**.  
+   - Outgoing calls are held until storage confirms that write is **durable = committed under the current lease epoch** (not merely accepted in memory / local WAL).  
+   - ClawQL patch: after each LTX PUT, **confirm GET** before advancing `synced_seq` so the gate cannot release on a PUT survivors cannot read.  
+   - If confirmation does not arrive in time, **never send** (safe).
+
+2. **Incarnation in lease + refuse live steal (`CELLD_REFUSE_LIVE_INCARNATION`, default on)**  
+   - Process generation already lives on the node lease (`ownership_index_generation`).  
+   - ClawQL patch: **refuse to start** if a still-live foreign generation holds that node ID (duplicate-identity guard for pinned IDs).  
+   - ClawQL patch: **refuse node-log bundle PUT** when the record is not Open at the shipper epoch (stale writer never lands orphan objects → never gets ack → never sends).
+
+3. **Enforce in celld’s runtime fetch path** (`op_fetch` / `gated_channel_send`), not in each Worker — no program can skip it.

 Harness still scored these as `failureClass=availability` (`no_expected_outcome` / first-404 terminal; running process predates mid-flight 404 retry). **Do not publish correctness = 0** for this board: four programs’ pretends-journaled state are absent from R2-backed DO storage, and 494 never got a durable write intent. That also fails the state-preserved reading of “journaled mid-flight state survives.” Outside writes still `writeCount=0` / no duplicates — the wrongness is **lost journal**, not a repeated write.

 Despite the gate, ClawQL N=1000 settle found mid-flight hangs with **no durable intent** on R2/DO storage (and 494 with create meta only). So either the gate released on a proof survivors cannot restore, a stale incarnation wrote a discarded generation, or local `synchronous=NORMAL` position advanced ahead of true LTX durability.
 
 ## One fix (closes H1 + H2) — landed in ClawQL fork (PR #1453)
 
-1. **Fenced acknowledgment (`CELLD_FENCED_ACK`, default on)**  
-   - Every storage write returns a **sequence / position**.  
-   - Outgoing calls are held until storage confirms that write is **durable = committed under the current lease epoch** (not merely accepted in memory / local WAL).  
-   - ClawQL patch: after each LTX PUT, **confirm GET** before advancing `synced_seq` so the gate cannot release on a PUT survivors cannot read.

 ## Restore claim only when
 
-1. Forked celld binary (`0.4.0-clawql.1`+) is pinned on CI / boards.  
-2. Kill-after-fetch + stale-incarnation tests **pass** (required).  
-3. Trace checker + TLA weak configs still fail the weak cases.  
-4. v3 board: frozen option-2 criteria **and** every mid-flight trial verifies intent in R2; correctness includes lost-intent as failure.
