Session notes (rolled from the utilization footer)

Session 2026-08-13 21:26–2026-08-14 00:1xZ (work; +~2.5 GPU-h in- session — R0-A 2.12 ridden launch→GO boundary + R1-A’s first ~0.3, exploit; R1-A continues overnight ~14.4 GPU-h under babysit ticks): CPU window 21:26–21:55 built+froze the re-scope (instrument, oracles, pre-reg); GPU busy 21:58→close except a 2-min env-crash gap (launch 1, MUJOCO_GL/transient-unit class — fixed in run_detached.sh, zero GPU-h lost). No idle debits.

Session 2026-08-13 18:02–21:0xZ (work; +~1.9 GPU-h — R0 launches 3–4 ridden to the STOP boundary, exploit): launch-3 tail ~0.93 (step-1 milestone banked, then the wave-1 worker OOM 18:57:55Z, fixed 78cbb65) + launch-4 resume ~0.94 (19:58:20→20:54:30Z rc 0). Debit owned: ~1 h GPU idle 18:58–19:58Z — the crash watcher’s pgrep -f matched its own cmdline and missed the death; unit-based liveness since. R0 closed at ~3.8/5.5 GPU-h ops gate, STOP verdict at the boundary, R1’s ~13 GPU-h not spent on a collapsing configuration.

Session 2026-08-13 14:27–18:1xZ (work; +~2.3 GPU-h — R0 launches 1–3, exploit): instrument item 4 (loop harness, fa739e9) + run pre-reg FINALIZED (8548969) + R0 launched, crashed ×2, fixed ×2 (device mix 9ffc1c1; Adam-init OOM d0b9a44 — measured the text stack at ~3.9B params fp32), launch 3 live 17:56:31Z riding into the next tick. Banked despite the crashes: held-out baseline 1.868 + 2/20 (bit- reproduced), wave pace 0.58 GPU-h/64 eps. check.py 861 green throughout; blog + Space pushed each cycle.

Session 2026-08-13 14:22–14:3xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design, CPU critical path queued): quiet tick — no owner messages/reactions (14:23Z; the 14:09Z exchange closed at ~10 min silence after our 14:14Z answer), babysit exit 0 with 0 registered runs, nvidia-smi 0%/0 MiB, queue green (depth 2, 14 open). run_work_next armed 14:23Z for instrument item 4 (loop harness) + phase-2 pre-reg finalization — the pre-reg is what returns the GPU to work.

Session 2026-08-13 13:45–14:2xZ (work; 0 new GPU-h — CPU instrument critical path, exploit): token-GRPO instrument item 3 CLOSED retargeted to the molmoact2 surface (a268046): masked-softmax sampling + TokenRow capture on predict_action_discrete, driver row-emission wiring, replay collator + GRPO glue (bijou/molmoact2/replay.py), 7 CPU oracles (headline: replay reproduces the rollout’s logprobs ≤ 1e-5), check.py 849 green. Owner 14:09Z grammar-mask/seed-73 question answered in-channel with the measured divergence facts (reply id 1537464486334832700). Queue: ar-head-port CLOSED, item 4 (loop harness) + phase-2 pre-reg finalization = critical path.

Session 2026-08-13 13:40–13:4xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design, CPU critical path queued): quiet tick — no owner messages/reactions (13:40Z), babysit exit 0 with 0 registered runs, nvidia-smi 0%/0 MiB, queue green (depth 3, 15 open). Repair: arm-B results were committed into the prereg post at the 13:38Z close-out but the Space was never pushed — blog built + pushed. run_work_next armed for instrument items 3–4 + phase-2 pre-reg finalization.

Session 2026-08-13 09:44–13:3xZ (work; ~2.25 GPU-h — arm A 1.15 + arm B ~1.05, each ≤ its 1.5 gate, + smoke/preflight microreads, exploit): owner pivot absorbed (RL substrate = release molmoact2, AR GRPO) then the whole chain built AND executed: GRPO step (229d80f); AR-head port items a/b/c/d0 (beeb93e/526c4ad/2a9e540/931b9a5, 18 oracles) + real-checkpoint smoke; item (d) gate eval under the 11:07Z owner delegation — 1/100 successes, AR pathway success-capable, token-GRPO GO + the 6.8% zero-fallback brittleness finding; arm B (grammar-masked, paired) launched 12:29Z and ridden in-session to COMPLETE 13:31Z — registered improvement: paired B−A +0.728 cm CI95 [+0.147, +1.325] excl. 0, knock-aways 27→13, fallbacks 0/2,996; masked = default serving mode (d69c470).

Session 2026-08-13 09:17–09:4xZ (work; 0 new GPU-h — CPU lane, exploit): token-GRPO phase-2 instrument item 1 closed off the outage-recovered WIP (418715c) — 9 CPU oracles green (tests/test_token_rows.py), memo §8 bit-for-bit bar amended with the measured 2.4e-6 / 1e-5 bound, driver rows-written summary added; amendment + close posted in-channel; queue green (depth 2, 14 open), items 2–4 remain with the veto window open.

Session 2026-08-13 09:10–09:2xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design): credit-outage recovery tick — 06:59–09:10Z all sessions died on 429 out-of-credits (06:49Z work session 62 turns in, mid-instrument-implementation), 09:10Z boot clean. Orphaned token-grpo-phase2-instrument WIP audited (py_compile green) and committed (63bb1e2); all-clear posted in-channel 09:13Z; queue green (depth 2, 14 open); run_work_next re-armed for the CPU lanes (finish instrument off WIP / photometric-links pre-reg).

Session 2026-08-13 06:17–06:4xZ (work; ~0.03 GPU-h embeds, exploit): arm sub-part split pre-reg’d (06:18Z) + executed + closed in one session — links named the photometric target (88% of the arm’s keep-only delta on 6.1% px), both instances must be treated (sub-additive ~77–79% each), no_mount the lone toward-real removal (0.713→0.654) queued as rider. Artifacts on fontaine-reports, results in-channel 06:31Z; sim-arm-photometric-links queued.

Session 2026-08-13 06:14–06:1xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design): quiet tick — no owner messages/reactions (06:14Z), babysit exit 0 with 0 registered runs, nvidia-smi 0%/0 MiB, queue green (depth 2, 14 open). run_work_next re-armed for the CPU lanes (arm-appearance leg pre-reg / phase-2 instrument, veto window open).

Session 2026-08-13 05:59–06:1xZ (work; 0 new GPU-h — CPU-only design session, exploit): token-GRPO phase-2 design memo + pre-reg DRAFT posted (blog + Discord, curl-200) per the probe decision rule — measured-pace budget model (~0.75 GPU-h/RL-step, ladder ~33 GPU-h gate 35, repricing the 08-12 sketch ~5×), composite reward, surface fork (B recommended), 5 tripwires, instrument delta. Queue: memo item closed, instrument item queued (veto window). Launch pends the owner phase-2 go. run_work_next re-armed (CPU lanes queued).

Session 2026-08-13 05:17–05:5xZ (work; +~0.02 GPU-h — the pre-registered gate embeds, exploit): fg appearance pass legs (b)+(c) EXECUTED (2e15ae7) — real-crop clutter patches mined from the bank episodes’ own medians and pasted by inverse fisheye warp read 0.556 vs v3 0.713 (gate PASS at 3× the bar, 100/100 closer) and beat the no_clutter removal ceiling 0.576 (−0.020, 75/100): the appearance pass is CLOSED, promotion queued owner_hold (asked 05:40Z), arm-appearance leg queued next. run_work_next re-armed (CPU lanes queued).

Session 2026-08-13 03:48–03:5xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design): quiet tick — no owner messages/reactions (03:48Z), babysit exit 0 with 0 registered runs, nvidia-smi 0%/0 MiB, queue green (depth 2, 13 open). run_work_next re-armed for the CPU lanes (top-gap decomposition / token-GRPO phase-2 memo).

Session 2026-08-13 03:03–03:5xZ (work; +~0.1 GPU-h — the 4-arm lens gate probe + oracles, exploit): sim-fit-real-lens-model CLOSED — cubemap fitted-lens wrist path (25cf643, 8 oracles), gate decomposition: full fit FAILS (center double-counts the 08-12 pose fit, center-only arm reproduces it), curve-only refit PASSES 0.523 ≤ 0.548 (Δknn5 CI-excl-0, 96/100 frames closer, cost-neutral). Default flip = sim100 amendment 6, owner ask 03:40Z. Queue refilled with the top-gap decomposition screen.

Session 2026-08-13 03:02–03:0xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design): quiet tick — no owner messages/reactions (03:02Z), babysit exit 0 with 0 registered runs, nvidia-smi 0%/0 MiB, queue green (depth 2, 12 open). run_work_next re-armed for the CPU lanes (lens leg (b) / token-GRPO phase-2 memo).

Session 2026-08-13 01:48–02:5xZ (work; +~0.04 GPU-h — the paired contact-shadow gate probe, exploit): sim-composite-contact-shadows CLOSED with gate GO — real-arm shadow fit (contrast +0.091 CI-excl-0, zen 30°/az 112.5°), v4 render style + 12 oracles (8f35560), paired probe closed ~10% of the remaining top-cam knn5 excess (Δknn5 CI-excl-0, 66/100 seeds closer; wrist 100/100 tied). Default flip = sim100 amendment 5, owner ask posted 02:56Z. Queue refilled with token-grpo-phase2-design-memo.

Session 2026-08-13 01:18–01:5xZ (work, chained; 0 new GPU-h — CPU lane, exploit): sim-fit-real-lens-model leg (a) closed — plumb-line θ→r fit on the pinned real wrist frames (center 22 px off, corner ray placement −12.8 px vs equidistant, CI-excl-0), instrument + oracles + chart 5581d6d, results in-channel 01:40Z. check.py 801 green. GPU legs still pend owner calls.

Session 2026-08-13 01:14–01:2xZ (tick, babysit; 0 new GPU-h — GPU idle-by-design after the probe close): quiet tick — no owner messages/reactions (01:15Z), registry clean with declared reason, nvidia-smi 0%/0 MiB, queue green (depth 2, 12 open), boot audit clean. run_work_next armed for the CPU lanes (lens fit, contact shadows, phase-2 token-GRPO design). 08-12 entries rolled to the archive page.

Previous update 2026-08-13 21:26–2026-08-14 00:1xZ (real date -u at stamp: 00:09) — work session: the re-scope pre-reg landed AND its whole ladder moved in one session — instrument built + oracle-gated, R0-A frozen, launched, ridden to its boundary with every read GREEN, and R1-A (15 steps, overnight) launched by the frozen GO rule. The collapse read reversed: sampling diversity survived the update on exactly the seeds where R0’s died.

Status: LIVE: grpo_phase2_r1a (unit fontaine-grpo-r1a, 00:06:00Z resume of R0-A’s step_0002.pt, steps 3–17 at the frozen constants; registry entry current, leg gate 16.5 GPU-h, rc ETA ~14:3xZ 08-14; babysit probe eval trajectory from 1.8441 vs baseline 1.868). Preservation upload fontaine-upload-r0a detached (weights-only step_0002 → fontaine-checkpoints/grpo_phase2_r0a). Queue validate green (depth 3, 15 open).

Steering: none — reads empty at boot 21:27Z and every babysit poll (22:42, 23:30 — only my own posts consumed). Recorded: owner 👍 on the 22:10Z re-scope pre-reg announcement (endorsement of the frozen plan; the 11:07/11:18Z delegation governs, R0-A GO → R1-A was frozen-rule execution, not a confirmation wait).

Done: (1) Instrument for the re-scope (69b03e8): option-A trainable surface (FAST-block rows [151934, 153982) of the untied wte.embedding + lm_head, ~10.5M params, post-backward row-mask — oracle bit-compares rows outside the span through a real step), differentiable anchor-KL penalty (β·k3 inside the objective, per-chunk anchor reference forwards under ONE swap/step, heartbeat anchor_k3_pre), advantage clip, and the §7 KL numeric line mechanized (--kl-stop); 18 loop oracles, check.py 866→867 green. (2) Pre-reg FINAL frozen + posted (81e020c, posts/2026-08-13-prereg-token-grpo-phase2-r0a.md): option A + lr 1e-6

• clip ±2.0 + β 0.5 + eval-every 1 + kl-stop 0.06 (≈3× the 0.0215 JPEG-noise floor, below R0’s 0.0885 collapse), 2-step smoke gate 3.0 GPU-h, explicit INERT rule. (3) R0-A ridden launch to boundary: launch 1 died pre-GPU (MUJOCO_GL doesn’t survive into transient units — fixed both manager-side and in run_detached.sh, addendum 1, 9a29575); launch 2 21:58:04Z → rc 0 00:05:09Z, 2.12 GPU-h. Boundary GO, all reads green: wave-2 signal ALIVE (2.03 cm median std, 8/8 kept vs R0’s same-seed 0.0087/3-of-8), held-out 1.8441 2/20 Δ −0.0239 CI [−0.0716, 0.0] at step 1 AND endpoint, anchor_k3_pre 5.5e-07 (5 orders gentler than R0’s 0.067/step), VRAM 33.91 GiB (R0: 76.53), chosen_nll SOFTENED 0.766→0.866 (anti-sharpening). (4) R1-A launched 00:06:00Z by the frozen rule; knockaway watch carried (0.234→0.359 vs the 0.167 ×3 line — a legitimate exit-3 is registered behavior). (5) Queue ×2 (rescope-prereg CLOSED, r0a-run CLOSED with the verdict, r1a ride item queued); registry pruned+new entry; 4 in-channel posts (pre-reg announce, step-1 milestone, GO boundary; all Discord-markdown).

Next: queue_cli.py next → token-grpo-phase2-r1a-run (ride via babysit ~30-min ticks; rc ~14:3xZ 08-14 → §6 endpoint reads → R2-A only via the frozen R1→R2 rule; flat-at-noise eval through ~step 10 feeds an lr/β re-price discussion at the boundary, no early hand-stop). run_work_next armed; queue.json canonical.*

Previous update 2026-08-13 21:02–21:2xZ (real date -u at stamp: 21:08) — tick: the history check caught two owner questions UNANSWERED (19:05Z “explain this experiment again”, 20:03Z “which molmoact2 implementation — the bijou first-class one?”) — both answered in-channel 21:1xZ; the missed-reply incident owned and a structural harness fix queued.

Status: no live runs (unchanged — the R0 STOP verdict stands; next GPU leg pends the re-scope pre-reg). Queue validate green (depth 3, 15 open); run_work_next still armed from last session.

Steering: the two questions above (informational, no decision changes), answered 21:1xZ. Also recorded late: a 👍 on the 20:00Z launch-4 resume post (owner endorsement of the crash-diagnose + resume handling) — it was visible in history last session but went unrecorded under the same incident.

Done: (1) Both answers posted — a plain-words explainer of the token-GRPO phase-2 experiment + R0’s role/verdict, and the molmoact2 answer: yes, the bijou first-class port on the whole live path (bijou/molmoact2/ predictor/processing/replay via sim/grpo_loop.py; weights from allenai/MolmoAct2-SO100_101, no trust_remote_code; allenai’s HF module is only the frozen byte-parity reference) — verified in the run code before answering. (2) Incident diagnosed: the prior session’s babysit-embedded reads at 20:0x/ 20:55Z DID consume the messages (cursor advanced) but its notes say “reads empty” — consistent with the babysit poll section being truncated in that session’s terminal handling; consume-once semantics then buried the questions (~2 h / ~1 h reply latency). (3) Queue item discord-unreplied-inbox added (queued, after the rescope pre-reg): read appends surfaced non-bot messages to a state-file inbox, boot/babysit print the pending count as a loud FIRST line, only an explicit ack clears — result posts never do. (4) Conversational hold via a history-based monitor (cursor untouched) through ~21:2x; no owner follow-up by close.

Next: unchanged head — token-grpo-phase2-rescope-prereg (CPU, new pre-reg in-channel before any launch); the inbox fix rides the same chained work session. run_work_next armed.*

Previous update 2026-08-13 18:02–21:0xZ (real date -u at stamp: 20:58) — work session: R0 ridden to its boundary across two more launches — the first gradient step on the 4B text stack SURVIVED with every step-1 gate green, the run completed rc 0, and the frozen boundary reads said STOP: one-step policy collapse + VRAM over gate. R1 not launched; the re-scope pre-reg is queued at head.

Status: no live runs — grpo_phase2_r0 COMPLETE 20:54:30Z rc 0 (launch 4), babysit entry pruned 20:55Z with the STOP verdict; no_live_runs_reason declared (next GPU leg pends the re-scope pre-reg). Queue validate green (depth 2, 14 open).

Steering: none all session — reads empty 18:02Z, 18:5xZ, 20:0xZ, 20:55Z (babysit-forced). The owner’s 17:31Z “How’s stuff?” was answered 18:01:42Z before this session opened. The 11:07/11:18Z delegation governs; the STOP is the frozen pre-reg rule executing, not a confirmation wait.

Done: (1) R1 launcher prepped during the wave-0 gap (59806be). (2) Launch-3 step-1 milestone banked (row 18:54:02Z, ~10 min early): the Adam step survived with ALL gates green — mean_ratio 1.00138, clip 0.132, median group std 4.17 cm, 8/8 groups, KL sane (approx 0.0232 / anchor 0.0215), 4/64 sampled successes, 0.76 GPU-h/step measured. Then crash 3 (18:57:55Z): a wave-1 rollout worker OOM’d at reset — post-step the parent retains the ~70 GiB activation peak as reserved cache and the 8 worker processes can’t fit; wave 0 never saw it (no Adam states yet). Fixed 78cbb65: release_cached_vram() before every wave/eval, plus a real resume-path bug found in prep (KL anchor snapshotted AFTER the restore → anchor_kl silently rebased onto resumed weights; fixed + new resume oracle, 13 loop oracles, check.py green). (3) Launch 4 = RESUME of step_0001.pt (19:58:20Z; saved ~1.1 GPU-h, validated the exact resume path R1 would use, passed the crash point immediately) → COMPLETE 20:54:30Z rc 0, R0 total ~3.8 of the 5.5 GPU-h ops gate. (4) R0 boundary reads → STOP (addendum 3 + full results section in the pre-reg post): VRAM 76.53 GiB steady-state ≥ 75 (option B measured-marginal on 1×H100); wave-2 signal collapse (median group std 4.17 → 0.0087 cm, 5/8 groups with all 8 draws identical); endpoint held-out greedy 1.868 → −0.0, 0/20, paired Δ −1.868 CI95 [−4.41, −0.03] entirely below zero. Mechanism recorded: one step at lr 5e-6 sharpened the policy (chosen_nll 0.77 → 0.33, anchor_kl 4×/step) — R0’s gates did their job for ~3.8 GPU-h instead of R1’s ~13. Checkpoints stay on local disk as diagnostic artifacts (STOP boundary consumes nothing; upload rule not triggered). Registry pruned; queue ×2 (run item CLOSED with the verdict, re-scope item queued at head); in-channel posts 18:5xZ, 20:0xZ, 20:5xZ. (5) Watcher bug owned + fixed in-session: the crash-3 watch loop’s pgrep -f matched its own cmdline, so the GPU sat idle ~1 h before the 19:5x relaunch — subsequent watchers use unit-based liveness.

Next: queue_cli.py next → token-grpo-phase2-rescope-prereg (CPU): the registered option-A fallback (dissolves the VRAM fail) + collapse mitigation priced off the R0 curves (lr down 5–10×, advantage tempering, KL penalty with the measured 0.0885/step scale, eval-every 1), NEW pre-reg in-channel BEFORE any launch; ~31 GPU-h of the 35 ladder total remains. run_work_next armed. queue.json canonical.*

Previous update 2026-08-13 14:27–18:1xZ (real date -u at stamp: 18:00) — work session: the phase-2 critical path CLOSED end-to-end and the first RL training run is LIVE on its third launch — instrument item 4 landed, the run pre-reg FINALIZED, R0 launched 14:58:55Z, two plumbing crashes diagnosed + fixed same-session (a cuda/cpu device mix, then an Adam-init OOM that measured the real model size), launch 3 live 17:56:31Z.

Status: LIVE: grpo_phase2_r0 launch 3 (unit fontaine-grpo-r0, 17:56:31Z on d0b9a44; babysit entry current). Banked from launches 1–2: step-0 held-out baseline 1.868 composite, 2/20 greedy successes (reproduced bit-identically across launches); wave pace ~35 min/64-episode sampled wave (~0.58 GPU-h, inside the estimate); full gradient accumulation clean. Crashes: launch 1 rc 1 15:51Z (device mix in grpo_objective_sums, fixed 9ffc1c1); launch 2 rc 1 17:12Z (OOM at Adam init — the option-B text stack is ~3.9B params fp32, a ~4B-class model; fixed d0b9a44: foreach=False, CPU-staged anchor swap, expandable_segments; projected peak ~68–70 vs the 75 gate). Ops gate 3.5 → 5.5 GPU-h (addendum 2; ~1.85 spent on crashes), ladder total 35 unchanged. Queue validate green (depth 2, 14 open).

Steering: none all session — reads empty 14:27Z, 14:51Z, 16:1xZ, 17:0xZ (babysit-forced). The 11:07/11:18Z delegation governs; §4 option-B veto window passed unanswered → B frozen. Full trail in-channel: 15:02Z launch post, 16:15Z crash-1/fix, 17:5xZ crash-2/fix (ids …333104275476, …893340004372, …312609022104).

Done: (1) instrument item 4 CLOSED (fa739e9, check.py 861 green): sim/grpo_loop.py — sampled rollout wave → composite reward → group z-filter → chunked sum-form GRPO step (gradient-invariant chunking, oracle-pinned; option-B text stack fp32/TF32, vision frozen) → anchor-KL (k3 off recorded logprobs) → paired held-out eval → mechanized §7 tripwires (exit 3) → babysit train-jsonl heartbeat; 12 CPU oracles incl. a loop e2e. ALL 4 instrument items closed. (2) Run pre-reg FINALIZED (8548969 + addenda 1–2): checkpoint allenai/MolmoAct2-SO100_101, constants frozen, on-surface R0 signal gates. (3) R0 launched ×3 with same-session diagnosis + fix + oracle

• addendum per crash (9ffc1c1, d0b9a44); registry current; queue ×2; posts/index.md repair; blog + Space pushed each cycle.

Previous update 2026-08-13 14:22–14:3xZ (real date -u at stamp: 14:24) — tick, babysit: quiet tick — no live runs, no new steering; the 14:09Z owner exchange held open to the ~10-min silence handback, run_work_next armed for the critical path (instrument item 4 + phase-2 pre-reg finalization → GPU legs launch).

Status: no live runs — babysit exit 0, 0 registered; nvidia-smi 0%/0 MiB (idle-by-design until the phase-2 pre-reg lands — the CPU critical path IS the unblock). Queue validate green (depth 2, 14 open).

Steering: none new — read empty 14:23Z; history-5 shows no reactions and no owner follow-up to our 14:14Z grammar-mask/seed-73 answer (~10 min silence at close → conversational window handed back; a short in-session watcher covered the tail of the window). The 11:07/11:18Z delegation stands.

Done: liveness/queue/GPU verified; run_work_next armed 14:23Z so the driver chains straight into a work session for the critical path.

Next: chained work session → instrument item 4 (loop harness: rollout wave → score → z-filter → step → periodic eval + babysit heartbeat + registry entry), then phase-2 run pre-reg finalization (memo §5 ladder at the measured pace, §4 option B — veto window passed). GPU legs launch on the finalized pre-reg per the delegation. queue.json canonical.*

Previous update 2026-08-13 13:45–14:2xZ (real date -u at stamp: 14:18) — work session: token-GRPO instrument item 3 CLOSED on the molmoact2 surface — the RL rollout draw (masked-softmax sampling + TokenRow capture on predict_action_discrete) and the replay collator landed oracle-gated (a268046, check.py 849 green); the loop harness (item 4) + run pre-reg finalization are all that stand before the phase-2 launch.

Status: no live runs — GPU idle-by-design until the phase-2 pre-reg lands (babysit registry empty, reason declared). Queue validate green (depth 2, 14 open); molmoact2-ar-head-port CLOSED (arm B read banked; the (b2) HF-parity remnant unqueued, low priority — the behavioral gate passed both arms).

Steering: owner 14:09Z — explain the grammar-masked decode (“do we do constrained decoding?”) + why seed 73 flipped (“malformed actions zero-filled?”) → answered in-channel 14:14Z (id 1537464486334832700) with the measured facts: yes, constrained decoding over the action block under the symbol-budget mask, identical to the reference stream wherever greedy was already legal; seed 73 was NOT zero-filled in arm B (impossible by construction) — the arms’ distance series are bit-identical through tick ~473 then diverge (A succeeds at 622, B ends 10.2 cm; seed 1 is the mirror image), 47/100 seeds diverged, and at 1/100 competence the paired delta (+0.728 cm CI95 excl. 0), not the success count, is the registered read. Per-seed fallback attribution was not banked in arm A — the item-3 instrument records per-predict streams, so phase-2 rows will carry it. No reply as of 14:2xZ; the 11:07/11:18Z delegation stands.

Done: token-grpo-phase2-instrument item 3 (a268046, retargeted per the 10:02Z steering): predict_action_discrete gains grammar-masked SAMPLING (Gumbel-max off stable_sample_rng keys; sampling requires the mask — unconstrained sampling would sample the 6.8% fallback class) + per-step ActionCaptureStep capture, so token_rows_from_capture + TrainingRowWriter work unchanged off this surface; driver wiring (--molmoact2-temperature, --emit-training-rows on the discrete path storing SHIM-APPLIED model-unit state, --draws with temperature); bijou/molmoact2/replay.py (row loader, bins-only grammar-mask recompute + bit-equality guard, one-shot teacher-forced replay_logprobs WITH graph, molmoact2_grpo_loss into the decoder-generic surrogate). 7 CPU oracles — headline: replayed chosen logprobs reproduce the rollout’s records within the registered 1e-5 bound, greedy AND sampled (fixture note: the tiny trunk’s real lm_head stopped below the <action_i> block; the replay oracles build it widened, build_predictor(vocab_size=156032)). Queue ×2 (port closed, item 3 folded).

Next: queue_cli.py next → instrument item 4 (loop harness: rollout wave → score → z-filter → step → periodic eval + babysit heartbeat + registry entry) then the phase-2 run pre-reg finalization (memo §5 ladder at the measured pace, §4 option B recommended — veto window passed unanswered).

Previous update 2026-08-13 13:40–13:4xZ (real date -u at stamp: 13:42) — tick, babysit: quiet tick after the arm-B close-out — no steering, no live runs; one repair: the 13:38Z close-out committed the arm-B results into the pre-reg post but never pushed the Space — blog rebuilt + pushed this tick.

Status: no live runs — babysit exit 0, 0 registered (arm B pruned at the 13:38Z close-out); nvidia-smi 0%/0 MiB. Queue validate green (depth 3, 15 open). Standing result from the prior session: arm B COMPLETE 13:31Z — grammar-masked decode is a registered improvement (paired B−A progress_final +0.728 cm, CI95 [+0.147, +1.325] excludes zero; knock-aways 27→13; fallbacks 0/2,996 by construction; successes 1/100 each arm, A: seed 73 / B: seed 1) — masked = default serving mode per the delegation.

Steering: none new — read empty 13:40Z; history-5 shows no reactions yet on the 12:29Z arm-A results or 13:33Z arm-B paired-read posts. Delegation (11:07/11:18Z: decide + keep GPU busy, no confirmation waits) stands.

Done: liveness/queue/GPU verified; blog built + Space pushed so the prereg page now serves the arm-B paired read (was committed d69c470 without a push); now.md brought current (arm B complete, not live), oldest body entry + aged footer notes rolled to the archive.

Next: chained work session (run_work_next armed 13:39Z) → critical path: instrument items 3–4 on the molmoact2 surface (sampling mode + TokenRow capture on predict_action_discrete, replay collator, loop harness) + phase-2 run pre-reg finalization (ladder re-priced at the measured ~0.4 s/chunk). GPU is idle-by-design until that pre-reg lands. queue.json canonical.*

Previous update 2026-08-13 09:44–12:4xZ (real date -u at stamp: 12:32) — work session: owner pivot absorbed AND the gate answered — the release molmoact2’s AR/token pathway is SUCCESS-CAPABLE in our sim (1/100 at greedy), token-GRPO lane is GO on it; the entire chain built and executed same-session: GRPO step → AR-head port (codec, discrete decode, masked RL decode, sim adapter) → 100-seed gate eval → arm B (masked) live.

Status: LIVE: molmoact2_ar100b_masked (arm B, launched 12:29Z, unit fontaine-molmoact2-ar100b, gate 1.5 GPU-h, boundary ~13:3xZ — babysit entry active; ~100% util at first poll). Queue validate green (depth 3, 15 open). check.py 842 green. Session GPU spend ~1.2 GPU-h (arm A 1.15 + microreads).

Steering: heavy and decisive. 09:45Z owner question (use the 9/100 release ckpt exclusively?) → answered with the flow-vs-AR architecture fork → owner 10:02Z: their FAST/AR head was also trained — wire it, focus molmoact2 + AR GRPO (plan 👍’d) → owner 11:07Z: “you make the decisions, ensure we make progress and GPU is always busy” → 11:18Z: “don’t wait for my confirmations”. Delegation active: proceeding by frozen decision rules, full trail in-channel.

Done: (1) token-GRPO instrument item 2 CLOSED (229d80f): bijou/train_grpo.py — DAPO-clipped advantage-weighted token-CE off the SFT scaffold, 7 oracles (ratio≡1 ≡ weighted-CE bit-exact, zero-advantage → exact-zero grads, train mask == rollout mask). (2) molmoact2-ar-head-port items a/b/c CLOSED (beeb93e/526c4ad/ 2a9e540): released OpenFAST artifact behind a native codec (bit-parity fixture generated by executing THEIR code; release quirks pinned — 1005/2048 trained bins, 7 quantization-hole symbols), predict_action_discrete (their unconstrained-greedy reference op-for-op + tolerant span extraction), grammar_masked RL decode (budget arithmetic on their BPE piece lengths, every draw decodable by construction). (3) Real-checkpoint smoke PASS (f0afc1e): all emissions well-formed + decodable, masked mode 0 violations / bins identical to greedy. (4) Port item (d0) CLOSED (931b9a5): --molmoact2-discrete driver adapter + preflight PASS. (5) Item (d) EXECUTED under the 11:07Z delegation (pre-reg frozen faa5855 pre-launch, results 42c4485): 1/100 successes (seed 73 — a flow-success seed) ⇒ AR pathway success-capable, token-GRPO GO per the frozen rule; validity green (strikes 0, 1.15/1.5 GPU-h); finding: 6.8% of greedy predicts (202/2991) zero-fallback — the model’s emissions fail their own decoder ~1-in-15, exactly what the masked decode repairs. (6) Amendment-1 arm B (grammar-masked, same seeds, paired read) frozen + launched 12:29Z. Queue re-scoped ×4.

Next: arm B boundary ~13:3xZ → paired read + prune (next session; run_work_next armed). Then the critical path: instrument items 3–4 on the molmoact2 surface (sampling mode + TokenRow capture on predict_action_discrete, replay collator, loop harness) and the phase-2 run pre-reg finalization (ladder re-priced at the measured ~0.4 s/chunk pace). queue.json canonical.*

Open asks unchanged: phase-2 go + surface fork + instrument veto (memo §9), clutter-patch promotion, sim100 amendments 5 + 6, v3-rerun unhold + arm set, GRPO cells 3/4 re-queue.

Done: item 1 of token-grpo-phase2-instrument closed (418715c): tests/test_token_rows.py — capture is pure observation (bit-identical greedy actions); recorded packbits mask reconstructs bit-for-bit from ids alone; sampled rows are exactly the decoded stream (codec.decode(ids) == actions bitwise), key-reproducible; writer round-trip + loud guards. Measured amendment to memo §8 (surfaced in-channel, id 1537394335086288937): greedy logprobs vs teacher-forced re-forward is NOT bitwise — one-shot vs incremental trunk forwards carry reduction-shape noise, chosen logprobs within 2.4e-6 on the fixture (bound 1e-5); the masked-softmax reduction itself IS bit-exact. Draw-0-reproduces-banked rides the first real GPU emit. Driver now prints a rows-written summary at close.

Done: outage diagnosed from harness logs (62-turn work session died mid-implementation of token-grpo-phase2-instrument item 1); boot audit recovered the orphaned diff — TokenRow capture surface, --emit-training-rows + TrainingRowWriter, 287 lines across policies/model/rollout — verified coherent (imports + py_compile green) and committed as WIP 63bb1e2. run_work_next re-armed.

Fresh v3 0.713 = the banked anchor exactly; real-fg 0.328 (real arm/boat/hand pixels re-lit via the bank affines, pasted on a different drawn plate by the production arithmetic — at the clean anchor 0.283, below the 0.5 null: the pipeline can reach real-level, only the pasted pixels are wrong); arithmetic residue +0.004 AUROC (paired +2.3e-07 CI-excl-0 — ~5% of the armless shift, under the +0.05 bar); armless arms 0.869/0.865 read FARTHER (0/100 closer) — labeled confound, no-arm is itself OOD; crop reads 0.989/0.988 near-ceiling but the registered box covers the arm region (restates the verdict); v4 paired read replicated the shadow gate (−8.3e-08, 66/100 closer).
