Session 2026-08-09/10 23:55–02:xxZ (work, bounded; 0 new GPU-h by the session itself — er_60k rides 5.4/155 at write, tiny10k 4.0/15; explore): lit-radar-0821 closed in one pass via a 5-agent fan-out — 4 Papers pages (QoQ offline-influence pole, Curse of Precision sim-only-fit + clarity-filter lever, NeuralActuator SO-101-is-the- platform with everything released, GigaWorld/WMBench graded-videos-not-rollouts + artifact objection dead), hook corrections on all four, ideas #9/#16 fed, Radar 0821 flipped + 0822 queued (12/18 survived, 3 dups already-read). Space pushed, 4 pages 200; summary in-channel; check.py 599 ×2. Held live for the er_60k step-5000 ER-init delta boundary (~02:0xZ).

Updated 2026-08-09 23:51–00:0xZ (real date -u at write: 23:53) — tick (babysit): green tick, no steering — er_60k probe 16.78@1500 keeps descending (33.03 → 22.05 → 16.78), the ER init stays ahead of the 40k early curve; both runs ride.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — step ~1,500, probe 33.03@500 → 22.05@1000 → 16.78@1500, util 97–99%, vram ~71.5 ×4, 4.1/155 GPU-h (the 9.1 st/min short window is the step-1500 eval pausing training inside a ~2-min poll gap, not a stall — util and vram steady). fontaine-tiny10k LIVE local — step ~3,600, probe 11.52@3500, 3.7/15 GPU-h; endpoint ~05:1xZ 08-10.

Steering: none — read empty, history ×5 only already-handled traffic; the ~150 GPU-h correction remains unobjected → er_60k rides.

Done: babysit ×1 exit 0 (both runs green, no gate crossings). Queue validate green depth 2 (10 open). run_work_next confirmed armed → lit-radar-0821. Body + footer rolled per the last-2 rule (22:51 block + 22:51/23:21 notes → archive).

Next: chained work session → lit-radar-0821 (cpu, GPU-busy window). er_60k step-5000 boundary ~02:0xZ 08-10 → async-save capture line + er60k_init_delta_chart.py → post chart + facts in-channel. tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read. er_60k endpoint ~08-11 ~12:00Z → chained panel_v2 k4l2.*

Updated 2026-08-09 22:34–22:5xZ (real date -u at write: 22:44) — tick (babysit): the whole ER-60k arc closed inside one tick — owner go 22:36Z → adamc KILLED 22:40Z → param sheet 22:43Z (with the 0.19% natural-share correction) → owner approval 22:45Z (“uniform sampling … is fine, I’ll fine-tune later. Parameters look good”) → seed override 22:46Z caught pre-step-1 → fontaine_molmo2_er_60k_ddp4 LIVE at 22:53Z, seed 0.

Status: fontaine_molmo2_er_60k_ddp4 LIVE on box 4×H100 (unit fontaine-er-60k, relaunched 22:53Z at seed 0; first launch 22:50Z at the sheet’s seed 2 stopped PRE-STEP-1 22:52Z when the owner’s seed override crossed it, ~0 GPU-h lost). Gate 65 GPU-h; 40k-class rate ~0.92 s/step ⇒ endpoint ~08-10 ~14:00Z; first-poll facts owed next session (E1 banner 880 ds / 38,628 eps / 18.67M fr; s/step; vram vs 77; wall projection in-channel). adamc final: step ~11.8k, ~35.7/310 GPU-h, probe ladder ended 10.30@11500 = run-best (3-rise watch receded); step_010000 kept on box, weights-only upload to fontaine-checkpoints in flight (unit hf-up-adamc10k; optimizer 32.6 GB stays local), train_log.jsonl banked box+local for the zero-GPU post-mortem chart. ER snapshot verified COMPLETE on box (0 incomplete blobs, all shards). fontaine-tiny10k LIVE local — step 2,060, 22.1 st/min, 2.4/15 GPU-h; probe 16.78@500 → 14.52@1000 → 13.04@1500 → 11.74@2000 descending on schedule. Host RAM 72 GiB available (drift 86→80→77→72 across ticks, record-only; amendment holds). Endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read ~06:3xZ.

Steering: owner 22:36:23Z “my rig datasets = cleaned and v2 and yes, you have my go” + 22:40Z ids-correct confirmation (caught ≤2 min via the in-session 60 s Discord monitor; conversational mode held). Executed same-session: kill, ckpt/log banking, dataset resolution, detached upload+pull units, param sheet. Sheet approved verbatim 22:45:23Z — owner picked uniform/natural sampling over my 5% --dataset-repeat recommendation (“I’ll fine-tune later”; the sheet’s correction stands recorded: rig = 0.19% ⇒ ~0.15 expected views per rig frame — accepted as an owner cost-call). Seed override 22:46:40Z (“let’s use the same seed too”) = seed 0, the 40k shuffle seed, explicitly overriding the fresh-seed standing rule — arrived after the 22:50Z launch, caught pre-step-1, relaunched 22:53Z. Launch confirmed in-channel 22:5xZ. No open owner questions.

Done: babysit ×1 exit 0 (22:34; adamc 11,780 @ 22.1 st/min pre-kill, tiny10k 1,920 @ 22.1). adamc killed at owner go (charter owner-call class, not a gate kill; babysit.toml entry pruned with full disposition note). Queue item owner-er60k-run-prep-0809 updated (ER download complete). Pre-reg draft updated in place (open-inputs section → resolved/executed/arithmetic-pinned). run_work_next armed for the chained session (param-sheet finalization + launch on approval, else lit-radar-0820).

Next: er_60k first poll next session (E1 banner + s/step + vram

• projection in-channel; babysit entry live with the K1-class kill lines; pre-reg updated in place — the ER-init delta vs the 40k probe curve is the primary read). Chained work session → lit-radar-0820 (CPU, GPU-busy window). tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity readout. AdamC post-mortem chart = queued zero-GPU item. MolmoAct2 follow-up arms + ArmnetBench checkpoint watch remain owner-decision / watch items.*

Previous update 2026-08-09 23:21–23:2xZ (real date -u at write: 23:26) — tick (babysit): green tick, no steering — er_60k first probe 33.03@500 = the same early class as the 40k baseline (30.844@500), the ER init starts on equal footing.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — step ~760 @ 23.6 st/min (2.5 s/step window, inside the corrected 2.2–2.6 class), vram ~71.5 GiB ×4, util 69–99%, 2.1/155 GPU-h. First probe 33.03@500 vs 40k baseline 30.844@500 / adamc 31.30@500 — same early class, no anomaly; the primary ER-init delta read stays at step 5000 (~02:0xZ 08-10, with the async-save capture line owed in-channel). fontaine-tiny10k LIVE local — step 2,960 @ 21.9 f/min, probe 11.64@2500 descending, 3.2/15 GPU-h.

Steering: none — read empty, no new reactions (history ×5 checked). The ~150 GPU-h cost correction (posted 23:01Z) remains unobjected → er_60k rides.

Done: babysit ×1 exit 0 (both runs green). Pulled the 40k early-probe anchor (30.844@500) from the post-mortem chart’s transcribed curve for the @500 comparison. Queue validate green depth 2 (10 open). now.md footer rolled to the last-2 rule (22:34 / 22:07 blocks + 22:03/22:07/22:34 notes → archive). run_work_next confirmed armed.

Next: chained work session → lit-radar-0820 (cpu, GPU-busy window). er_60k step-5000 boundary ~02:0xZ 08-10 → probe ladder vs 40k (ER-init delta) + er60k-init-delta-midrun-chart item. tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read. er_60k endpoint ~08-11 ~12:00Z → chained panel_v2 k4l2.*

Previous update 2026-08-09 22:07–22:5xZ (real date -u at write: 22:50) — work session (bounded): lit-radar-0819 CLOSED — 4 Papers pages same session via 5-agent fan-out, and the first hook in 9 sweeps to STRENGTHEN on contact (Squint: the rollout-substrate blocker is mechanically gone). Mid-session owner steering (22:14Z): proposed Molmo2-ER 60k run replacing adamc — feasibility verified + draft pre-reg posted within the hour; and adamc’s 3-rise probe watch RESOLVED as a recede (10.30@11500, new run-best) — surfaced in-channel for the kill call.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE — babysit ×3 exit 0 (22:11/22:26/22:45), step 11,640, ~21–23.5 st/min, 35.3/310 GPU-h, vram 75.3 ×4. Probe 10.30@11500 = NEW RUN-BEST — the 3-consecutive-rise watch resolved as the recede-precedent class predicted; owner kill proposal (22:14Z) pending owner confirmation with this fact posted. Endpoint ~08-12 ~17:00Z if it rides. fontaine-tiny10k LIVE local — step 1,520+, ~20 st/min on projection, 2.1/15 GPU-h; probe 16.78@500 → 14.52@1000 → 13.04@1500 descending on schedule. Host RAM 143/221 used, 77 GiB available (80→77 drift, record-only; amendment holds). Endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read ~06:3xZ.

Steering: owner 22:14:00Z — Molmo2-ER init question + proposed ER-60k run (matched 40k params, rig data from step 0, kill adamc). Answered 22:19Z: ER verified drop-in (config diff = RoPE metadata only; safetensors manifests identical keys + identical 19,403,476,800 bytes; launcher change = --backbone allenai/Molmo2-ER). Draft pre-reg posted (post); ER snapshot download started on box (unit hf-dl-molmo2-er); queue item owner-er60k-run-prep-0809 opened. Awaiting: kill go + rig dataset pointers + mixture call (no oversample flag exists — natural share vs small code addition). Tight-polling until answered.

Done: lit-radar-0819 CLOSED — 4 Papers pages (squint, action-space-design, so101-vla-benchmark, cl-triangle), all curl-200. Headlines: Squint — MIT SO-101 twin in ManiSkill3, install-verified, 96.1→91.3% ranking-preserving sim→real; correction: vendored not upstreamed; far-OOD default visuals → relative screens first; #16 gains a design problem not an access problem, #6 gains free sim labels, #22 unparks as relative screens. Action-space — hook strengthened: code+data verified, chunk-wise delta-joint beats our absolute cell 88.0 vs 79.6 in-class → idea #23 opened (page); decode-identical cells differ 8–15pp in rollouts = standing offline↔rollout inversion caveat. SO-101 bench — n=20/cell, leaky multi-label taxonomy, execution labels saturate 91–100%; prize = 16 unlisted rollout_* Hub datasets (unlabeled, ~2–3 h self-label pass to use). CL triangle — contradiction dissolves: zero-replay FT always forgets; replay ρ 0.02–0.2 @ ~20% batches suffices (real-robot 3B full-FT) → #17 unfreeze price list, #4 free drift instrument + LoRA-joint rung candidate, #16 rig-phase replay clause. Ideas #4/#5/#6/#16/#17/#22 fed + #23 opened; Radar 0819 flipped ✅ + Radar 0820 table added. Refill: 4 new angles → 16 verified, only 2/16 dups (both already deep-read; one independently re-converged on our banked offline-validation page) → lit-radar-0820 queued (4 priority hooks + 10 spares). check.py 599 green; Space pushed, 7 new/changed pages curl-200.

Next: owner reply opens owner-er60k-run-prep-0809 (param sheet ~30 min after inputs; launch only on sheet approval). Else queue_cli.py next → lit-radar-0820 (CPU, GPU-busy window). tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity readout. adamc endpoint ~08-12 ~17:00Z if it rides the kill call. MolmoAct2 follow-up arms + ArmnetBench checkpoint watch remain owner-decision / watch items.*

Session 2026-08-09 22:34–22:5xZ (tick, babysit; 0 new GPU-h — adamc stopped at ~35.7/310 final, tiny10k rides 2.4/15): ER-60k GO landed mid-tick (owner 22:36Z “my rig datasets = cleaned and v2 and yes, you have my go”; ids confirmed 22:40Z — caught ≤2 min by the in-session 60 s Discord monitor). adamc_100k killed clean 22:40Z at step ~11.8k — final probe 10.30@11500 = run-best; step_010000 kept on box + weights-only upload to fontaine-checkpoints (hf-up-adamc10k), train_log.jsonl banked box+local for the zero-GPU post-mortem. Rig datasets resolved: so101_pick_place_clean (7 ep / 3.4k fr) + so101_pick_place_v2 (50 ep / 32.7k fr), already in ~/datasets on box, LeRobot v3.0 compatible. Param sheet posted 22:43Z with a mixture CORRECTION: natural share = 0.19% = arithmetically invisible (loader path-dedup blocks zero-code oversample) → –dataset-repeat @ ~5% recommended; awaiting approval

• pick. ER snapshot verified complete on box. babysit ×1 exit 0; tiny10k probe 11.74@2000 descending; host RAM 72 GiB available (drift record-only). babysit.toml adamc entry pruned; queue item updated; run_work_next armed (launch-on-approval else lit-radar-0820). POST-NOTE same tick: approval 22:45Z + seed override 22:46Z + launch 22:50Z (seed 2, stopped pre-step-1) + relaunch 22:53Z seed 0 LIVE — er_60k babysit entry live, launcher launch_box_fontaine_molmo2_er_60k_ddp4.sh committed, pre-reg updated in place; adamc step-10k weights-only upload VERIFIED DONE on fontaine-checkpoints; rig dataset Hub pull done (both already in ~/datasets).

Session 2026-08-09 22:07–22:5xZ (work, bounded; 0 new GPU-h — adamc rides 35.3/310, tiny10k 2.1/15; explore): lit-radar-0819 closed — 4 deep reads + fresh sweep as 5 concurrent subagents, 4 Papers pages (squint, action-space-design, so101-vla-benchmark, cl-triangle); Squint = first hook in 9 sweeps to strengthen on contact (rollout-substrate blocker mechanically gone); idea #23 opened (chunk-wise delta-joint, 88.0 vs 79.6 in-class); CL triangle adjudicated (replay ρ 0.02–0.2 suffices). Mid-session owner steering 22:14Z: ER-60k proposal — ER init byte-verified drop-in + draft pre-reg posted + box snapshot download started within the hour; adamc 3-rise watch resolved recede (10.30@11500 new run-best), surfaced for the kill call. Refill 14/16 clean → 0820 queued (4 hooks + 10 spares). check 599; Space pushed ×2.

Session 2026-08-09 22:03–22:1xZ (tick, babysit; 0 new GPU-h — adamc rides 33.6/310, tiny10k 1.9/15): green tick, no steering (read = own 22:01 post only; no new reactions). adamc step 11,080 @ 22.3 st/min; probe 11.41@11000 = third consecutive rise off the 10.63@9500 run-best — logged as a named probe-rise watch (record-only per pre-reg, no kill line touches it; prior upticks receded within 1–2 evals). tiny10k step 1,240 on projection, probe 14.52@1000 descending; host RAM 141/221 used, 80 GiB available — amendment holds. Queue green depth 3 (9 open); run_work_next armed (22:04) for lit-radar-0819.

Session 2026-08-09 18:21–18:2xZ (tick, babysit; 0 new GPU-h — adamc_100k rides, 18.8/310): run healthy at step 6100 — babysit exit 0, 8 procs, ~75.3 GiB ×4 vs 77, window 21.6 st/min. Probe ladder unchanged since @6000 (band 12.1–12.6); @6500 ~18:40Z routine → chained work session reads it + works lit-radar-0812b. Clock audit: second future-stamp catch in two sessions (queue.json 18:30Z + a projected “18:4x” now.md header from the 18:01 session) — both corrected, watch item posted for future sessions. Discord clean (read = our own 18:19 post only, no reactions); queue green depth 3 (8 open); run_work_next armed (18:19 marker).

Session 2026-08-09 18:01–18:2xZ (work, bounded; 0 new GPU-h — adamc_100k rides, 18.3/310) [note back-filled by the 18:21 tick — the session rolled the head but skipped its own footer note]: lit-radar-0811 CLOSED — all 5 banked hooks deep-read, 5 Papers pages same session (TCFM 2605.08511, RLDT 2606.08602, FAN 2604.01570, HiFlow 2603.27281, VLA-JEPA 2602.10098), ideas #11/#12/#16/#17/#19 fed; refill sweep → lit-radar-0812b queued (5 dup-checked hooks). Probe@6000 = 12.591 read in-session — oscillation band 12.1–12.6, no escalation; train_mae 13.47 flattening. Truncated-read process catch recovered via full history (no owner message missed). Queue green depth 3; blog built + Space pushed; in-channel post; run_work_next armed.

Session 2026-08-09 03:12–03:2xZ (tick; 0 GPU-h new — the live swap arm pre-registered and counted): babysit exit-3 on subgoal_swap judged CONTINUE — the ~3.2 GPU-h projection is a phase-roll artifact (frame counter resets at identity→swap, cumulative divides swap-only frames by time-since-launch; true swap rate ~590 f/min, rc ~03:45Z, ~1.6 GPU-h ≤ 3 gate); diagnosis anchored in babysit.toml, generic multi-phase-counter babysit.py fix owed to the chained work session (run_work_next already armed). Discord read + history clean; queue validate green depth 3.

Session 2026-08-09 01:43–03:1xZ (work, bounded, chained; exploit, ~5.5 GPU-h box ladder closed this window + ~1.6 GPU-h local swap arm live, both pre-registered): perf-pass1 box ladder CLOSED 02:26:32Z + frozen decision executed — C −7.3% / B −10.8% vs A on the true 4×DDP recipe = NO bundle landing, P1 dead twice over (owner relative-bound question moot), P2+bitwise split to a hygiene item; results post + chart + analysis json banked, true-cost overrun owned (~5.5 vs 3.0 ceiling, loads uncounted). Subgoal-swap instrument delta landed oracle-green same session (16 fixture tests, check.py 554) + arm LAUNCHED 02:13:47Z — identity phase BYTE-reproduced the banked oracle arm (oracle (ii) GREEN, 25,800 rows), swap arm live at close. Discord read clean at every babysit; ladder readout posted.

Session 2026-08-09 01:36–01:5xZ (tick; 0 GPU-h new — the live ladder pre-registered and counted): perfpass1_box gate-crossing judged — projected ~5 GPU-h vs the 3.0 ceiling (model loads undercounted), CONTINUE recorded in-channel (healthy, fixed-scope, kill would waste the spent 3 GPU-h and void the C-vs-A decision); babysit.py check_progress_log bare-count fallback landed (step-style logs false-failed liveness every poll; 538 green) — the fix is what surfaced the gate fact; prior session’s mid-write state (anchor + queue audit note) committed. Discord read + history clean.

Session 2026-08-09 00:34–01:0xZ (tick, held open through the fields-panel boundary; 0 GPU-h new — the live run pre-registered and counted): babysit 00:35Z exit 0 (fields panel 4,352/6,450, 98–100% util, proj 3.1 ≤ 6 gate); held to 00:56Z — 6,432/6,450, rc=0 imminent at hard-kill budget → run_work_next armed, chained session owns the readout + babysit prune + perf-pass1. Cleaned up the prior session’s mid-write state: now.md placeholder tokens filled (that session was killed mid-commit), perfpass1 PREPARED timestamp typo fixed. Discord read + history clean (no messages, no reactions since the 23:38Z report link). Queue validate green depth 3. Previous update 2026-08-09 22:03–22:1xZ (real date -u at write: 22:06) — tick (babysit): green tick, no steering — one new watch item: adamc’s probe has now risen three consecutive evals (10.63@9500 → 10.80@10000 → 11.06@10500 → 11.41@11000), a trend rather than the usual one-eval blip; record-only per the pre-reg, no kill line touches it.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE — babysit exit 0 (22:03), step 11,080, 22.3 st/min, 33.6/310 GPU-h, vram 75.3 ×4 vs 77. Probe-rise watch: prior upticks (@5000, @8000, @10500-as-of- last-tick) each receded within 1–2 evals; this one is 3-for-3 rising. Kill lines unaffected (would need >25 ×3; the @2500 line was passed at @10000); same record-only class as the train_mae drift — chart at readout. Next eval @11500 ~22:2xZ. Post-kill-line cruise, endpoint ~08-12 ~17:00Z. fontaine-tiny10k LIVE local — step 1,240, 22.3 st/min, 1.9/15 GPU-h; probe 14.52@1000 descending on schedule; first save boundary @1250 imminent.

Probe 11.06@10500 — a mild uptick above the 10.63@9500 run-best, the @5000/@8500 recede-precedent class, record-only. Post-kill-line cruise, endpoint ~08-12 ~17:00Z. fontaine-tiny10k LIVE local — step 800, 20.2 st/min (~2.97 s/step, on projection), 1.5/15 GPU-h; host RAM 134/221 used, 86 GiB available — the workers-10/prefetch-2 amendment holds (mild growth vs 21:17’s 122/221, comfortable margin, record-only). Next probe @1000 ~21:5xZ. Endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read ~06:3xZ.

Steering: none — read surfaced only our own 21:41 lit-radar post; history -n 5 shows no new reactions (the 21:03 👍 was already recorded). 13:48Z gate default (let run, gate 310) governs adamc.

Previous update 2026-08-09 21:24–21:4xZ (real date -u at write: 21:37) — work session (bounded): lit-radar-0817 CLOSED — 4 Papers pages in ~15 min wall clock via 5-agent parallel fan-out (4 deep reads + the refill sweep concurrently), every banked hook needed corrections again; the refill sweep hit 12/16 corpus dups — the pool is drying.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE — babysit exit 0 ×2 (21:25, 21:37), step 10,480 @ 21:37, 22.0–25.8 st/min, 31.8/310 GPU-h, vram 75.3 ×4 vs 77. Run-best 10.63@9500 stands; post-kill- line cruise, endpoint ~08-12 ~17:00Z. fontaine-tiny10k LIVE local — step 660 @ 21:37 (22.0 st/min), 1.4/15 GPU-h; first post-relaunch probe @500 = 16.78 vs the pre-OOM run’s 16.46@500 — same-seed sanity confirmed (stale row now superseded in the ladder). Endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read ~06:3xZ.

Steering: none — read empty at boot (21:24) and at the 21:37 babysit. 13:48Z gate default (let run, gate 310) governs adamc.

Done: (1) lit-radar-0817 CLOSED — 4 Papers pages same session (armnetbench, safecast, reflex + legato cluster, compression-gap; MolmoAct2 slot satisfied by the 08-09 owner deep dive). Hook corrections, three loud: ArmnetBench “3,118 human-labeled” = 2,518 scored rollouts

• 600 unscored demos, and the claimed 84 policy checkpoints are NOT public (→ #9 calibration study specified-but-blocked, watch item) — but the 2,288 labeled SO-101 failure rollouts are real, Apache 2.0, LeRobot-native (→ #16’s LWD prerequisite met, #6’s eval corpus); SAFECAST is NOT offline (needs closed-loop perturbed re-executions + hundreds of labeled rollouts) and its flow-policy cells land below coin-flip in its own metric → #6’s cheapest next step sharpened into a go/no-go separability gate on the hidden-state-probe family; Legato “~10% smoother” wrong both directions (smoothness ~flat; real headline −19–23% completion time vs matched RTC). Plus: Reflex’s 2.58× is vs a full-recompute strawman, but the timestep-invariance draws reframe is real (K draws share one trunk prefill → #19 cost split; stall-rate instrument adopted → #22); Compression Gap oversold on every clause (tiny non-VLA, single seed, mechanism asserted — filed consistent-with only, #19). Ideas #6 #9 #16 #19 #22 + index hooks fed. (2) Refill sweep → lit-radar-0818: 16 candidates abs-verified by the sweep agent, 12 dropped as corpus dups by local grep (agent’s exclusion-list check is insufficient — the executor must grep the full corpus per id; instrument note logged in the item); 4 clean hooks banked (ATHENA influence-function curation #9, ProbeAct #6, Qwen-RobotManip 38kh pipeline #9/#17, plasticity-at-scale adamc watch), NO spares — next slice should fresh-sweep with new angles first. (3) Self-caught a queue.json stamp 13 min future-dated (21:50 written at a real 21:37) — corrected same session; the 21:17 tick’s clock-audit class is live in my own writes.

Next: queue_cli.py next → lit-radar-0818 (CPU, GPU-busy window) after the owner-side docs-pass tail; run_work_next armed at close. tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity readout (MolmoAct2 15.5% expert-ratio anchor in hand). adamc endpoint ~08-12 ~17:00Z → chained k4l2 panel.

Step-10,000 kill line JUDGED PASS: “probe not below its own @2500 value by 10k” — @2500 = 14.0294 (fetched from the box jsonl), @10000 = 10.80, clear by 3.23; run-best 10.63@9500 stands (the 10.80@10000 is a one-eval uptick, the @5000/@8500 precedent class). The babysit window’s 5.6 st/min (21:14→21:17) was the @10000 boundary itself — async save “captured in 21.2s” + probe eval; re-verified 10020→10040 in 54 s (~22 st/min) right after.

Steering: read empty; history -n 5 surfaced an owner 👍 on the 21:03 OOM-recovery + deep-dive-plan post — lightweight agreement with the recovery call and the piece, recorded per the 08-05 reaction protocol, no reply owed. 13:48Z gate default (let run, gate 310) governs adamc.

Done: (1) step-10,000 gate judged (Status — the first of adamc’s two dated kill-line checkpoints is behind us). (2) Clock-hallucination audit: the 20:47 work session closed at a real 21:15:31Z (commit 72e2016 push time) but stamped 21:45/21:5x — queue.json updated_utc was 30 min in the FUTURE; fixed there + in the head entry below (ack/link times corrected to 21:04Z/21:14Z from Discord history).

Previous update 2026-08-09 14:54–15:0xZ (real date -u) — tick (babysit): adamc_100k healthy through step 1560 — probe@1500 banked at 16.8716, down hard again from 24.48@1000.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0, 8 procs, ~75.1–75.3 GiB ×4 vs the 77 bar, step 1560 at the 14:55 poll, window 18.7 f/min (probe eval@1500 inside the window; steady neighbors 2.54–2.57 s/step). Probe@1500: eval_chunk_mae 16.8716, train_mae 18.1248 — the fall continues (31.30@500 → 24.48@1000 → 16.87@1500), far under the 25 sustained-×3 bar that only binds after step 5000. Loss 4.99@1560 falling smoothly, grad-norm 5–7 flat (record-only AdamC watch — no ramp), vram alloc peak 70.57, zero NaN/inf in the log. Cumulative 5.0/310 GPU-h. Next boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel — the chained session catches it); kill-bar comparison binds at eval@2500 vs @10k (~08-10); endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report).

Steering: none — read surfaced only our own fjoint-instrument post; history -n 5 all our own posts, no reactions. The 13:48Z gate question stays unanswered; declared default (let it run, gate 310) governs.

Done: babysit poll (exit 0, unfiltered) + log-level anomaly scan (probe@1500 pulled from the box log; grad-norm flat 5–7; NaN/inf count zero; the window-rate dip attributed to the in-window eval@1500); queue validate green depth 4 (9 open); run_work_next left armed (GPUs busy + CPU items queued). Stable stretch → exited rather than held.

Next: chained work session → queue_cli.py next pointer (boundary-incompat-read-npz free npz read, or docs-pass-followups-0809 / lit-radar-hooks-0812a); queue.json canonical. fjoint launch remains owner-gated post-adamc-endpoint (~08-12 ~17:00Z+), sequencing question to the owner at finalization. adamc_100k boundaries: async-save quote ~17:2xZ (chained session), eval@2500-vs-@10k comparison ~08-10, endpoint ~08-12 ~17:00Z → chained panel → leaderboard row + grad-norm chart.

Previous update 2026-08-09 14:37–14:5xZ (real date -u) — work session (bounded, one item): the fjoint instrument is LANDED oracle-gated (pre-reg finalization condition 1 of 3) — the rung now waits only on the owner’s sequencing go.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0 ×2 this session (14:37, 14:49), 8 procs, ~75.1–75.3 GiB ×4 vs the 77 bar, step 1460 at the 14:49 poll, window 23.6 f/min ≈ 2.54 s/step (no eval in window), loss falling smoothly, 4.7/310 GPU-h. Next boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel — the chained tick catches it); kill-bar comparison binds at eval@2500 vs @10k (~08-10); endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report).

Steering: none — read clean at boot and both babysit polls; history all our own posts, no reactions. The 13:48Z gate question stays unanswered; declared default (let it run, gate 310) governs.

Done (49ee316): fjoint instrument, pre-reg Instrument §1–§3 (the queue-head CPU part of idea4-fjoint-rung-finalize-exec): (1) materialize_fjoint_init.py — composite warm start (F@10k expert/prompt/trunk bytes verbatim + phase-1 FAST tables as joint_ce.safetensors, joint metadata section; trunk-coherence byte-guard refuses a wrong phase-1 source, inode fast path for the box’s hardlinked layout); (2) --joint-unfrozen-seam guard escape in train.py — warm-start-only (requires --init-from, contradicts --seam-stop-grad, naive-joint refusal verbatim-preserved for fresh runs), banner prints seam UNFROZEN (flow grads enter the trunk), plus a real hole closed: the molmo2-only runtime guard now checks --joint-ce too (a gemma joint run under the escape would have silently dropped the rider); (3) AR-view compat verified against J-written checkpoints via the real writer on the fixture family. 12 new oracles (tests/test_fjoint_init.py), check.py 596 green (was 584). Draft post’s Instrument section updated in place + idea #4 page + index hook; queue item updated, validate green depth 4 (9 open); Discord summary posted; blog built + Space pushed, draft page curl-verified 200.

Next: queue_cli.py next pointer → boundary-incompat-read-npz (CPU, free npz read) or docs-pass-followups-0809 / lit-radar-hooks-0812a; queue.json canonical. fjoint launch remains owner-gated post-adamc-endpoint (~08-12 ~17:00Z+), the sequencing question goes to the owner at finalization. adamc_100k boundaries: async-save quote ~17:2xZ (chained tick), eval@2500-vs-@10k comparison ~08-10, endpoint ~08-12 ~17:00Z → chained panel → leaderboard row + grad-norm chart. run_work_next armed.

Previous update 2026-08-09 14:09–14:1xZ (real date -u) — tick (babysit): adamc_100k healthy through its first probe eval — step 560, probe@500 banked (eval 31.30 / train 33.04), rate back at 2.56–2.61 s/step steady.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0, 8 procs, GPUs 72–89% at poll, vram alloc peak 70.4 steady vs the 77 bar. First probe @500: eval_chunk_mae 31.2959, train_mae 33.0448 — high-in-absolute is expected mid-warmup from base; no bar binds before step 5000 (>25×3) and the trajectory anchors are @2500/@10k. Loss 5.76@560 falling smoothly (action 5.26, CE-aux 1.00), grad-norm 12.9–14.9 (record-only AdamC watch). The babysit window’s 17.4 f/min (~3.45 s/step) is fully explained by the probe eval inside it — step-520’s s_per_step 4.949 amortizes the eval, neighbors 2.56–2.61. Cumulative gate projection 2.0/310 GPU-h. Next boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel).

Steering: none — read clean, no reactions on our posts via history. The 13:48Z gate question (let-it-run vs act-ckpt refit) is ~25 min unanswered; declared default (let it run, gate 310) governs and nothing blocks on it, so tick cadence resumes — the chained session re-checks.

Done: babysit poll + log-level anomaly scan (probe value, rate dip attribution, grad-norm trajectory — all clean); queue validate green depth 3 (8 open); run_work_next already armed 14:08 by the prior close-out, left in place (GPUs busy + CPU items queued).

Next: chained work session → idea4-f-then-joint-prereg-draft (CPU, in the run’s shadow) or lit-radar-hooks-0811a / docs-pass-followups-0809. adamc_100k boundaries unchanged: save + async line ~17:2xZ, kill-bar comparison binds at eval@2500 vs @10k (~08-10), endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report) → leaderboard row + grad-norm chart.

Previous update 2026-08-09 12:47–13:5xZ (real date -u) — work session (4-h budget): both owner top-priority items closed — AdamC implemented, oracle-tested and LAUNCHED as the new 100k run from base Molmo2-4B (after a three-message approval exchange, including a λ override caught before step 1), and the docs modernization pass landed for the owner’s main-rebase.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE on the box (unit fontaine-adamc-100k, relaunched 13:30Z after the λ override) — base Molmo2-4B, 100k steps, eff-batch 32 (8/rank ×4, microbatch 2), vision tower unfrozen from step 0 (banner: 439.1M vision params @ 2e-5), text 2e-5, decoder 1e-4, warmup 1000, AdamC λ=1e-5, seed 1, save 5000, ZeRO-1 + chunked backward + async saves. Banners verified: E1 dataset gate exact (878/38,571/18,636,749), AdamC partition 4074.7M corrected / 2.6M head / 0.6M 1-D. In dataloader spin-up at write time — first log window’s measured s/step + vram peak owed to the channel (babysit adamc_100k entry live: kill bars NaN/inf, @10k<@2500, >25×3 after 5k, 77 GiB near-OOM watch, 260 GPU-h gate; grad-norm = record-only AdamC watch).

Steering (13:19:10Z + 13:24:10Z, both actioned same session): (1) approvals on the parameter sheet — text+vision 2e-5 confirmed, seed 1, save-every 5000, no smoke, launch the real run (OOM ⇒ restart at microbatch 1); λ pushed back (“0.1 high — what’s standard?”) → grounded answer posted (openpi ≈0, OpenVLA finetunes 0.01), launched at 0.01. (2) λ override 13:24Z: use the 40k/60k lineage value 1e-5 — caught before the first optimizer step (run was in model-load), stopped, relaunched clean at 1e-5 (amendment 2 on the sheet). ⚠ Process: the 13:19Z reply sat unseen ~35 min while I was heads-down in the docs pass — new memory rule: after asking the owner anything, poll every ~3–5 min until answered.

Done: (1) AdamC (401d6f7): --optimizer adamc = stock fused AdamW with per-group time-varying decay λ̂=λ·γt/γmax; partition corrected/head/no-decay with tied-lm_head care (Gemma AR decoder’s tied embed-head routed as one param, one group; unaudited decoders refuse; BOTH optimizer modes now hard-assert disjoint exact cover of the trainable set); 10 new oracles incl. bitwise AdamW equivalence at peak lr + the ZeRO-1 wrapper→local sync contract; check.py 584 green. (2) Parameter sheet + 2 amendments (post) posted before launch; launcher launch_box_fontaine_molmo2_adamc_100k_ddp4.sh (63b977c + λ fix); box synced via the git side-branch route (GitHub key absent on box). (3) Docs pass (e7144c3, owner 12:28Z request): README two-trunk + fontaine-vs-shared split; architecture .md modernized end-to-end (Molmo2 in intro/§1/§2, curated-plan ledger in §7, shipped-flag demotions in §8, CLI-default corrections, residual/seam/snapflow documented, §5 gains AdamC + memory machinery

• async saves); 4 historical docs got archive headers; subagent staleness audit against HEAD drove the pass; deferred tail queued as docs-pass-followups-0809.

Next: queue_cli.py next → molmo2-stage2-attachment-decision memo (F-only basis, CPU) in the run’s shadow; docs-pass-followups-0809 + lit-radar-hooks-0811a in any gap. adamc_100k boundaries: first kill-bar reads bind at the eval@2500 → @10k comparison (~08-10); endpoint ~08-11/12 → chained k4l2 panel (–report) → leaderboard row + grad-norm chart.

Previous update 2026-08-09 12:16–12:4xZ (real date -u) — work session (bounded, chained via run_work_next): the radar backlog cleared TWICE over — four papers deep-read, four pages landed same session (QDepth-VLA, ForesightFlow, CLP fewer-layers, Qwen-VLA); two fresh production frozen-first votes filed on #4’s ledger hours before tonight’s Δ_seam read, and the selection cluster gets its first direct evidence that selector shape beats selector size.

Status: attach_K healthy at the 12:22Z poll — step 3940/10k, loss 3.13, 3.776 s/step (endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / 4 GPUs. Probe 11.2033@3500 (best); first kill-bar 12.6394 binds ≥5k (~13:3xZ) with ~1.4 margin. CE aux flat. Local GPU free.

Steering: none — read clean at boot and at the 12:22Z babysit; nothing from the owner after the answered 11:43:03Z loss_action question, no new reactions.

Done: three lit queue items executed same session they were queued (lit-radar-hooks-0809b → -0810a → -0810b, each refill consumed in-window per the standing precedent), four papers pages: (1) QDepth-VLA 2510.14836 — third aux-spatial recipe class (expert-generative VQ depth tokens, monocular pseudo-labels, tokens RIDE the inference context unlike VEGA/SF); ablation split carried loudly (−2.9 loss vs −8.5 expert: the scaffold, not the geometry, carries most of the win) → #11/#17/ #5. (2) ForesightFlow 2606.04968 — seventh selection flavor; the K-sweep is the evidence anchor (separate 500M critic FLAT K=1→5, self-scored +5.0 = third strike on post-hoc probe selectors); 1-NFE endpoint preview instrument (τ 0.83, ~97% gain retained) → #19/#1/#12/#16. (3) CLP fewer-layers 2606.20246 — 33–50% of finetuned-VLA depth is CKA twins (8/16 DiT expert layers free); throughput fourth lever class, CKA map banked as a one-forward-pass diagnostic → #17. (4) Qwen-VLA 2605.30280 — early-fusion pole staked; Stage I trains the expert trunk-FROZEN = F-then-joint production vote #2 beside RDT2, filed pre-Δ_seam; τ=0.6 deploy sharpening = production cool-side dT sighting → #17/#4/#19/#16. Two sweeps: no stage-2/actckpt re-ranker found; 2 new hooks banked (SEAM 2607.04609 boundary-jerk, Robot Critics 2606.21572). Papers-index integrity fix (2 stale “unread” rows → page links); 2 future-dated queue stamps caught at write time and corrected against date -u (the 78cace5 class — my pacing sense runs fast; stamp at write, not at projected finish).

Next: 5k kill-bar binds ~13:3xZ (probe must be < 12.6394 — currently 11.20; babysit before session end catches or brackets the crossing); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision. queue_cli.py next → lit-radar-hooks-0811a (any GPU-busy window).

Previous update 2026-08-09 12:12–12:2xZ (real date -u) — tick (babysit): attach_K healthy past the run’s midpoint approach — probe margin ~1.4 held, all quiet; queue armed for the next lit slice.

Status: attach_K healthy at the 12:13Z poll — step 3800/10k, loss 3.10, 3.78 s/step (13.1 steps/min window; endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / 4 GPUs. Probe 11.2033@3500 (best); first kill-bar 12.6394 binds ≥5k (~13:2xZ) with ~1.4 margin. CE aux flat. Local GPU free.

Steering: none — read clean; history shows nothing from the owner after the answered 11:43:03Z loss_action question and no new reactions on our 11:48Z answer or the 12:12Z session post.

Done: babysit poll (exit 0, facts above — trajectories nominal, no anomaly beyond the CLI facts: loss stepping down 3.21 → 3.10, probe monotone-improving since 2500); queue validate green (depth 2, 8 open); run_work_next armed (chained work session takes lit-radar-hooks-0809b — QDepth-VLA + fresh sweep; banked radar backlog is empty).

Next: 5k kill-bar binds ~13:2xZ (probe must be < 12.6394 — currently 11.20; next tick catches the crossing); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision.

Previous update 2026-08-09 11:49–12:0xZ (real date -u) — tick (babysit): attach_K healthy at mid-run — probe margin ~1.0 held going into the 5k bar window; plus a future-dated queue stamp and 89 broken archive links caught and fixed.

Status: attach_K healthy at the 11:50Z poll — step 3460/10k, loss 3.18, 3.799 s/step (15.7 steps/min window; endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / 4 GPUs. Probe 11.6124@3000 (best); first kill-bar 12.6394 binds ≥5k (~13:2xZ) with ~1.0 margin. CE aux flat. Local GPU free.

Steering: none new — read surfaced only our own 11:48Z loss_action answer; history shows nothing from the owner after 11:43:03Z and no new reactions. Reply-watch on the loss_action thread held via a background history poll to ~11:59Z: quiet → normal cadence.

Done: babysit poll (exit 0, facts above); queue validate green (depth 2, 8 open) + two integrity fixes: (1) queue.json updated_utc was stamped 12:05:00Z — ~20 min ahead of the real clock (written during the 11:34–11:45Z work session; same class as 78cace5) — corrected to 11:45Z against the 1a41ffc commit-time anchor; (2) 89 root-relative links in archive/*.md (rolled verbatim from now.md, so papers/, posts/, journal.md, reports.md all 404’d one level deep) rewritten to ../ paths, grep-verified 0 remaining. run_work_next armed (chained work session takes lit-radar-async-exec).

Next: 5k kill-bar binds ~13:2xZ (probe must be < 12.6394 — currently 11.61); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision. queue_cli.py next → lit-radar-async-exec (any GPU-busy window).

Previous update 2026-08-09 11:11–11:3xZ (real date -u) — tick (babysit, then conversational): the 2500 probe uptick resolved as NOISE — probe@3000 = 11.6124, a new best; then an owner throughput question landed mid-close and was answered in-channel same tick.

Status: attach_K healthy at the 11:12Z poll — step 2880/10k, loss 3.25, 3.822 s/step (endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / all 4 GPUs loaded. Probe 11.67@2000 → 12.42@2500 → 11.6124@3000 (caught via a background watcher on the box jsonl): the uptick was noise, the trajectory resumes downward, and the first kill-bar 12.6394 (binds at ≥5k, ~13:2xZ) now has ~1.0 of margin. CE aux flat. Local GPU free.

Steering: owner 11:14:53Z (caught on the pre-close read): where are we on increasing training throughput for molmo2 AR? Answered in-channel 11:25Z with the assembled record: (1) the 08-08 review’s 8 findings; (2) pass-1 executed and killed by its own frozen rule — true-recipe box ladder A 2.251 / B(+cuDNN suffix) 2.495 (−10.8%) / C(bundle) 2.415 (−7.3%) s/step, both SLOWER, the 13× local microbench transfer falsified, P1 doubly dead (parity loss-bound fail too); bitwise-safe subset landed 6a4b45e with no speed claim; (3) the live lever is #20 actckpt (crash fixed 913fdc4, flag field-validated on the K arm right now; 4-rung ladder pre-reg drafted, ADOPT iff ≤1.02× control AND alloc ≤63 GiB, frees batch 12→16–20/GPU; blocked on a fresh AR-trunk launch — nothing AR-trunk is training now, so no run currently pays the cost); (4) ViT SDPA / valid-row CE / fused RMSNorm unmeasured solo (bundling hides sign), parked. Reply-watch held ~8 min after the answer — quiet → normal cadence (chained work session rejoins if the thread continues). No new reactions in history.

Done: babysit poll (exit 0, facts above); in-session hold for the step-3000 probe (charter §6 — cheapest resolution of the uptick watch item); queue validate green (depth 2, 8 open); run_work_next confirmed armed from the 11:08Z close (the chained work session picks up lit-radar-hooks-17).

Next: 5k kill-bar binds ~13:2xZ (probe must be < 12.6394 — currently 11.61); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision.

Previous update 2026-08-09 10:29–10:5xZ (real date -u) — tick (conversational): a dropped owner conversation caught and repaired — the 08:16Z “why does KI-joint exist” question AND the 09:53Z “did you miss my previous message?” follow-up had both been cursor-consumed unanswered; answered in-channel 10:36Z, reply-watch held through the tick.

Status: attach_K healthy at the 10:29Z poll — step 2240/10k, loss 3.26, 3.803 s/step steady (endpoint ~18:3xZ holds), vram 59.07 ≤ 71, probe 15.92@500 → 13.08@1000 → 13.01@1500 → 11.67@2000, already under the first kill-bar (12.64@5k) three probes early; CE-health aux ~2.6 flat (no drift signal). Local GPU free. Babysit exit 0.

Steering: two owner messages had been missed (consumed by read during earlier run-triage, never replied — the owner had to ping). Both answered 10:36Z: (1) why KI: the arms are gradient-decoupled but NOT equivalent — K’s trunk keeps taking CE steps on the robot-episode stream (text-lr 2e-5), so the residual taps the expert reads keep adapting to the deployment distribution; the π0.5-KI bet is that insulated adaptation outweighs the moving-target cost the owner named, Δ_seam prices exactly that, and F tying ⇒ frozen also wins on cost (no trunk backward). Drift is instrumented (CE-health watch + read-4 |Δ_AR| ≤ 0.3). (2) what the expert attends: NOT K/V export like the Gemma-4 path — Molmo2’s uniform full-attention stack has no KV-share boundary, so the pinned rule is residual taps: hidden states after layers 2, 5, …, 35 (stride 3, last tap on the final layer; 12 taps = 12 expert layers) through learned expert-side adapters into the trunk’s GQA geometry (8 kv-heads × head_dim 128, RoPE θ=5M), stop-grad on the taps. Feedback memory recorded: read is consume-once — every owner message it surfaces gets a same-session in-channel reply; result posts don’t count.

Done: the two in-channel answers; babysit poll (facts above); queue validate green (depth 2, 8 open); archive roll (keep-3).

Next: attach_K kill-bars first BIND at step 5000 (~13:0xZ); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read at matched endpoints → stage-2 decision. CPU window (chained work session, run_work_next armed): idea6-mcselect-postmortem (record-only, banked dump) + rejoin the owner thread if it continues (history rebuilds context).

Previous update 2026-08-09 07:50–08:1xZ (real date -u) — tick (held through the eval boundary per charter §6): F’s panel_v2 eval finished 5× faster than projected, the box freed inside the tick, and ARM K IS LIVE — the attach screen’s second arm launched 08:01:19Z, in-session.

Status: attach_K LIVE (unit fontaine-attach-k, launched 08:01:19Z via systemd-run; K_MEM_READY=1 B12c6 from the 60k endpoint, EXTRA_GPU_HOURS=17 recomputed from F actuals). At close: model-load phase done through FAST-table + adapted-backbone init, first jsonl steps pending — first-poll util+rate check in this entry’s Done, in-launcher rate gate fires on the first jsonl window (rc 2 = matched 5k downshift BOTH arms, F re-evals step_005000). Babysit attach_K entry live (3 probe kill-bars, vram 71 gate, CE-health watch). F panel_v2 eval COMPLETE 08:01:0xZ at ~1.24 GPU-h actual vs the 8.0 gate — scoring ran ~457 f/min once all shards hit steady state; the ~09:2xZ ETA (58.7 f/min) was load-phase-contaminated. F-side json/npz/html banked on the box; nothing is read from the F json alone — Δ_seam waits for K’s matched endpoint (frozen read attach_seam_results.py; state-copy 11.785 must be beaten decisively or the screen is void).

Steering: none (read clean 07:51Z; history = our own posts through 07:50Z, no reactions).

Done: (1) babysit poll on the eval caught the 457 f/min window rate → ETA collapsed from ~09:2xZ to ~08:0xZ → held the tick open per §6 instead of exiting; (2) bounded drain-watch (45 s polls), box READY 08:01:07Z, unit fontaine-attach-f exited clean; (3) K launched with box-sync verified (no box-relevant diffs since 6be4e8e — no mid-run pull needed) and EXTRA honestly recomputed 17 vs the header’s placeholder 25; (4) babysit registry: eval entry pruned (completion record kept), prepared attach_K entry armed with started_utc + the read-4 comparator corrected 40k→60k (amendment-2 repoint); (5) queue boundary updated, validate green depth 2.

Next: K first-poll completes this session if steps land before hard-kill (else the chained session’s first act); K ~10k steps at the rate gate’s measured s/step (smoke advisory 5.675 incl warmup — the gate, not the smoke, decides 10k vs matched-5k), then chained panel_v2 + AR-view drift panel → Δ_seam frozen read at matched endpoints → stage-2 decision. CPU window (chained work session, run_work_next armed): idea6-mcselect instrument.*

Previous update 2026-08-09 04:30–04:5xZ (real date -u) — tick (babysit, held through the verdict window per charter §6): K-smoke ladder GREEN at the first rung — full batch B12c6, no downshift — and the stage-2 attachment steer window is OPEN.

Status: no live GPU runs (babysit registry pruned to 0; box GPUs 0 MiB ×4, unit fontaine-attach-ksmoke inactive; local free). Rung 1 verdict 04:39:33Z: rc=0, vram_alloc_peak 57.34 GiB ≤ 71 gate (nvidia-smi peak 63887 MiB ≤ ~75000 advisory), 5.675 s/step; true ladder cost ~0.5 GPU-h ≤ 6 gate incl. the attempt-1 #20 crash. k_mem_ready rsynced box → local fontaine/harness/state/ (B=12, c=6 — launchers take K_MEM_READY=1 BATCH=12 BACKWARD_CHUNKS=6). Ladder’s own projection: K 10k ~63.1 of the 70 GPU-h batch gate (advisory; attach_rate_gate.py binds at launch).

Steering: none this tick (read clean 04:30/04:31Z; history = our own posts through 04:19Z, no reactions). Steer-window post up 04:42Z with the default named: launch the attach screen as written (arms sequential F then K, 10k each, B12c6) on the next session unless the owner steers — arm order / length / K-cost hold called out as steerable.

Done: (1) held the tick open through the rung-1 verdict (ssh watcher on the box verdict line), judged GREEN per the pre-reg pass rule; (2) k_mem_ready synced local before any launcher can want it; (3) babysit attach_ksmoke entry pruned (TOML re-validated, 0 live runs); (4) queue: idea4-attach-k-smoke-ladder closed done at ~0.5 GPU-h, molmo2-stage2-attachment-decision flipped blocked → queued with the window-open record; (5) steer-window post in-channel; (6) prior session’s uncommitted queue state (60k-panel zero-GPU-h close + actckpt-lineage-flip-prereg add) folded into this commit.

Next: chained work session (run_work_next armed): honor any owner steer from the window, else launch attach_F (unit + babysit.toml PREPARED entry ready), first-poll util+rate check; CPU window items: actckpt-lineage-flip-prereg.

Previous update 2026-08-09 03:50–04:1xZ (real date -u) — tick: caught and answered an owner question from 03:28Z that the previous session’s read cursor had consumed without replying (surfaced via the history check — exactly the gap that check exists for); the asked gap was real and is fixed.

Status: no live GPU runs (babysit 0 registered, exit 0); box + local free. Queue OK depth 2; run_work_next still armed — the chained work session owns the K-smoke ladder box claim.

Steering: owner 03:28Z asked (1) are the molmo2 60k eval reports linked from reports/? (2) is the checkpoint on the hub? Answer: hub yes (re-verified live: fontaine-checkpoints/ fontaine_molmo2_ar_60k_ddp4/step_060000, 4 files), reports page no — a real gap: the 60k panel json/npz/fields + the frozen analysis__molmo2_60k_vs_40k_k4l2.json were banked locally but never pushed to the Space, and reports.md had no @60k section (its 40k section still forward-referenced the fields pre-reg). Replied 03:57Z, fix confirmed in-channel 04:02Z. Owner follow-up 03:55Z (caught by the in-tick channel watch): “we should always generate the html reports for important checkpoints and link them from the blog” — ADOPTED as a standing rule (memory file html-reports-for-important-checkpoints + ack posted 04:1xZ): forward = endpoint evals include --report + reports-page/Space push on the close checklist; backfill = new queue item molmo2-60k-html-panel-report (~1 GPU-h record-only re-run, rides the next box claim with the K-smoke ladder, MAE must reproduce the banked 5.86022663460471 else stop-and-escalate).

Done: (1) pushed the three 60k jsons to the Space reports/ (panel, fields table, 60k-vs-40k analysis; npz stays banked local — Space convention is json+html only); (2) reports.md: new Molmo2 @60k section (links + hub checkpoint pointer + honest caveat: no per-frame HTML panel exists — the eval ran without --report; a browsable panel needs a ~1 GPU-h re-run, offered to ride the K-smoke claim if wanted) + the 40k section’s stale fields forward-reference updated; (3) blog rebuilt, book pushed, all 4 links curl-200. (4) Process note for future closes: post-eval checklist gains “reports page section + Space artifact push” — the 60k close (00:2xZ) and fields close (01:0xZ) both posted results but skipped the reports page.

Next: chained work session (run_work_next armed): idea4-attach-k-smoke-ladder on the free box (owner may add the 60k HTML panel re-run to that claim), then molmo2-stage2-attachment-decision steer window.

Previous update 2026-08-09 03:17–04:0xZ (real date -u) — work session (bounded, the chained rc owner): subgoal-swap CLOSED end-to-end — arm rc=0 03:42:36Z, all oracles green, frozen reads banked, verdict MIXED (both mechanisms real: ~40% format floor + ~60% content margin of the −0.290 slot value), results post + chart live — and the babysit phase-roll projection gap fixed generically.

Status: no live GPU runs — local GPU free 03:42Z (swap arm complete, ~1.5 GPU-h ≤ 3 gate), box free since 02:26Z. Next box claim = K-smoke ladder at the 60k warm start (idea4-attach-k-smoke-ladder, queued).

Steering: none (read clean 03:18/03:33/03:45Z; history = our own posts through the identity-green 03:11Z post, no reactions).

Done (this session): (1) babysit.py phase-roll fix (e8ef9d5): a counter reset vs the prev cache re-anchors the cumulative projection (phase_t0/phase_c0 persisted in state); GPU-h projected as elapsed + remaining-at-phase-rate — kills the 03:13Z false exit-3 class generically; 2 oracles anchored to the real numbers, check.py 556. (2) subgoal_swap_results.py (2f16951): the frozen reads mechanized (Δ_swap paired CI core + labeled via the dump join, swap-vs-oracle contrast, horizon mirror, 3-row table adjudicated from CIs, 10 abort branches under check.py, 557). (3) swap arm rc=0 03:42:36Z: dump oracles i+iv green in-unit (25,788/25,788 swapped, 0 empty, 0 skipped; 2,162 textual coincidences recorded). (4) Frozen reads executed (execution oracles green on the real artifacts): Δ_swap −0.113 [−0.161, −0.060] (wrong words HELP), swap−oracle +0.166 [+0.127, +0.205] (truth clearly better), horizon last-10 swap −0.175 vs oracle −0.480 (the banked −0.464 signature reproduced; NOT flat → the format floor compounds too). Table: MIXED, record-only per pre-reg — scorer escalations stay coherent, their prize is the ~0.17 content margin over a free ~0.11 any-words floor. (5) Results post + dark two-panel chart (CI dots + horizon fingerprint), idea-6 ledger line, queue item closed, babysit entry pruned (no_live_runs_reason set).

Next: queue_cli.py next → molmo2-perf-pass1-subset-landing (CPU, low urgency) / idea4-attach-k-smoke-ladder (box free NOW — the next GPU claim; green → owner steer window molmo2-stage2-attachment-decision → attach arms F then K). run_work_next armed at close.

Previous update 2026-08-09 01:43–03:1xZ (real date -u) — work session (bounded, chained): perf-pass1 box ladder CLOSED and read out — the bundle is SLOWER on the real recipe (C −7.3%, P1 −10.8%), nothing perf-claiming lands, P1 dead twice over; and the subgoal-swap instrument landed oracle-green + the arm launched same session — identity phase already BYTE-reproduced the banked oracle arm (the keystone oracle (ii), GREEN over all 25,800 rows), the content-wrong swap arm is live.

Status: Local subgoal_swap LIVE (unit fontaine-subgoal-swap, launched 02:13:47Z): identity full-panel pass done ~02:58Z rc=0 → oracle (ii) GREEN (identity npz byte-equal to the banked oracle arm, all shared columns, 25,800 rows; 25,788 swap records dumped) → swap arm (_swapsubgoal) live since ~03:00Z at ~546 f/min cumulative, rc ~03:4x–03:5xZ incl. the in-unit mechanical dump check (oracles i+iv, abort-on-red); ~1.6 GPU-h total ≤ 3 gate. Box GPUs FREE since 02:26Z (ladder closed) — next box claim = K-smoke ladder at the 60k warm start.

Steering: none (read clean at 01:45/02:18/02:37Z babysits; history = our own posts, no reactions).

Done (commits 190ecb0-era + this close): (1) subgoal-swap instrument delta (pre-reg posted 01:4xZ, implemented this session): bijou/eval/subgoal_swap.py map builder (judgments sidecar under the dataset’s own stamp = materialize’s exact selection; span model reproduces the persistent-row semantics so identity provably equals the oracle arm), pinned fraction-matching (nearest labeled frame, ties earlier), per-repo Sattolo derangement (order-independent seeding); BijouPolicy _swapsubgoal/_swapidentity wiring + per-frame provenance records; CLI --subgoal-swap-seed/ --subgoal-swap-identity/--dump-subgoal-swaps; 16 fixture oracles (check.py 554); launcher with the 4-phase abort-on-red sequence + subgoal_swap_live_oracles.py (selftest green, all abort branches fire). LAUNCHED 02:13:47Z. (2) perfpass1 box ladder readout (closed 02:26:32Z rc=0): OVERLAY PASS (0.0816 ≤ 0.3919 band); LADDER A=2.251s / B=2.495s / C=2.415s → B −10.8% / C −7.3% vs A — the frozen <5% branch executed: no bundle landing; P1 (suffix cuDNN) dead twice over (banked loss-bound fail AND −10.8% measured) so the owner relative-bound question is moot; P2+bitwise items split to new queue item molmo2-perf-pass1-subset-landing (CPU hygiene, no speed claim). Lesson recorded: local kernel microbenches don’t predict end-to-end under 4×DDP comms overlap; future bench gates count model loads (~5.5 GPU-h actual vs 3.0 ceiling, CONTINUE judged 01:42Z). Results post + house-dark dot chart + analysis json banked; Space pushed, links 200, Discord posted. (3) babysit self-match note added (driver-session log watchers can false-positive the subgoal_swap pgrep; the run is transient-unit-safe).

Next: swap arm rc ~03:4x–03:5xZ → chained session owns the dump- check verification, babysit prune, the frozen reads (Δ_swap paired CI / swap-vs-oracle / horizon mirror against the frozen 3-row interpretation table — the read script is the first CPU item) + results post. Then queue_cli.py next = idea4-attach-k-smoke-ladder (box FREE now) → owner steer window → attach arms. run_work_next armed.

Previous update 2026-08-09 01:36–01:5xZ (real date -u) — tick: perf-pass1 box ladder healthy mid-bench_A, but the 3.0 GPU-h ceiling crosses ~01:49Z with bench_B/C still queued — judged CONTINUE (charter §6: healthy, exactly the 5 pre-registered rungs; the estimate undercounted the 5 model loads); babysit.py step-log false positive diagnosed and fixed (was masking the gate fact entirely).

Status: box ladder overlay_A/B done (~01:14/01:24Z), bench_A 240/320 at 01:39Z (s_per_step ~2.3, ~71 GiB on all 4 GPUs), bench_B/C queued behind it; elapsed 2.3 GPU-h at 01:39Z → projected ~5 GPU-h at close (~02:2xZ) vs the 3.0 ceiling, crossed ~01:49Z. Judgment: CONTINUE to completion — the run is healthy and fixed-scope (5 pre-registered rungs, no runaway); a kill at the ceiling lands mid-bench_B, burns the ~3 GPU-h already spent, and leaves the C-vs-A decision (the ladder’s entire point) unanswered. Overrun cause owned: the ~2.5–3 estimate counted compute (~41 min × 4 ≈ 2.7 GPU-h) but not the 5 sequential model loads (~4–8 min each). Posted in-channel. Local GPU idle-by-design.

Steering: none (read clean; history = our own five posts from the chained session, no new reactions).

Done: (1) babysit.py fix — check_progress_log hard-required an N/M progress line, so step-style training logs ("step": N, no total) failed liveness at EVERY poll of perfpass1_box (two consecutive exit-1s with the log visibly rolling; NOT the anchored between-rung transient). Landed a bare-count fallback: count-only progress + the gpu-hours gate fed elapsed GPU-h (an honest floor that still fires once truly crossed) — this fix is what surfaced the ceiling crossing. check.py 538 green. (2) Prior session’s mid-write state committed (babysit false-positive anchor, queue subgoal-swap implementation-audit note).

Next: ladder rc ~02:2xZ → chained work session owns the OVERLAY + LADDER(BOX) readout, the frozen decision (C ≥ 5% median step-time vs A → bundle lands post-evals), babysit entry prune, and the actual-GPU-h ledger row; then the subgoal-swap instrument delta (CPU, audit banked, mapping pinned) in the GPU-busy window; K-smoke re-run at the 60k warm start after. run_work_next armed.

Previous update 2026-08-09 00:00–0x:xxZ (real date -u) — work session (bounded, chained): the two owed frozen reads BOTH LANDED — rung (b′) E6 FALSIFIED → NO-SCORER, and the 60k continuation read IMPROVED → the attach screen repoints to step_060000 (amendment 3 executed); fields panel launched on the box (readout owed to the chained session); lit slice landed its papers page (with a same-session audit correction).

Status: Box fields panel at tick end 00:56Z: 6,432/6,450 frames — rc=0 imminent (98–100% util all tick, babysit 00:35Z exit 0, cumulative projection ~3.1 ≤ 6 GPU-h gate); the launcher prints the record-only reads (accuracy block, narration delta, read-3 base-equality oracle) at rc=0 — the chained work session owns the readout + results post. Box perf-pass1 ladder: prereqs staged (branch bundled to the box, worktree flow-matching-perfpass1 at 22e8148, babysit PREPARED entry written) — opens when the box frees. Local GPU idle-by-design (no queued local claim).

Steering: none all session (Discord polled at every ~30-min babysit checkpoint + at both results posts; owner quiet since the 23:38Z report link reaction window).

Done (commits da47646, ea99aeb, 2d37f76, 205070e + close): (1) rung (b′) READ OUT — subset-join path landed in subgoal_draws_results.py (draws10/energy precedent, q4 slice fixture, 3 new abort branches, oracle green) and the frozen reads ran on the 23:52Z dumps: bon−self +0.210 [+0.113, +0.312] (E6 fires; Δ_bon +0.142 vs bare baseline = SC anti-selects), ceiling ALIVE −0.250 [−0.353, −0.148] (late-horizon −0.464) → NO-SCORER; results post + delta chart; selection family closed on scorer-free tricks. (2) 60k canonical read — new molmo2_60k_results.py (oracle-gated): paired Δ(60k−40k) −0.1388 [−0.194, −0.090] = IMPROVED; AR-100k bar NOT passed (+0.058; first_mae already under); no new probe low (probe/panel divergence recorded); decision executed: attach warm-start → step_060000, amendment 3 on the attach pre-reg, launchers + K-smoke + drift comparator repointed (oracle green), K-smoke re-run required; leaderboard row 8 + board row. (3) fields panel launched 00:03Z (box synced 2c10d96→bb03557 via git bundle — box deploy key can’t fetch; launcher grep guard hardened against a false-pass) — healthy end-to-end (6,432/6,450 by 00:56Z). (4) lit slice: uPRM 2605.10158

• SDN re-read (papers/label-free-selection-signals.md) — scorer design constraint “score the SET”; audit catch: SDN/jerkpick were already banked 08-08, page + hooks corrected same session. (5) perf-pass1 box prereqs: branch bundled, worktree at 22e8148.

Next: queue_cli.py next = molmo2-perf-pass1-exec (prereqs staged; 5 sequential runs ~2.5–3 GPU-h ≤ 3 gate; P1 loss-bound stays DROPPED per the banked local read — ladder runs A/B/C for the record) then the K-smoke ladder re-run at the 60k warm start (repoint executed, boundary rewritten) → owner steer window (stage-2 attachment decision) → attach arms. CPU: fieldcond-subgoal-meta-report (both pending inputs now in: fields numbers + (b′) verdict; draft slots pre-filled). Dated boundaries: fields panel rc=0 ~00:5xZ 08-09 (witnessed to 6,432/6,450; reads print at rc=0) → babysit entry prune + readout owed; perf-pass1 box ladder ~2.5–3 GPU-h ≤ 3 gate once the box frees.

Older entries: see the now archive — one dated page per day, verbatim.

Updated 2026-08-09 03:12–03:2xZ (real date -u) — tick: swap arm healthy mid-decode; babysit surfaced a gate crossing that is a phase-roll measurement artifact — judged CONTINUE (the run is on its pre-registered ~1.6 GPU-h ≤ 3 budget).

Status: subgoal_swap swap phase (_swapsubgoal) 8,032/25,800 frames at 03:13Z, true rate ~590 f/min (unit active, gpu0 12.7 GiB/63%) → rc ~03:45Z + in-unit dump check, exactly on the boundary. Babysit exit-3 cause diagnosed: the frame counter resets to 0 at the identity→swap phase roll, so the cumulative projection divides swap-only frames by time-since-02:13:47Z-launch → bogus ~132 f/min / ~3.2 GPU-h vs the 3.0 gate. Real total ~1.6 GPU-h. CONTINUE, no action on the run; diagnosis anchored in the babysit.toml entry. Box FREE (next claim K-smoke ladder).

Steering: none (read clean 03:13Z; history = our own posts through the 03:11Z identity-green post, no reactions).

Done: gate-crossing judged + phase-roll false-positive anchor added to babysit.toml (no code change this tick — the generic babysit.py gap, multi-phase logs with per-phase counters breaking the cumulative projection, is owed to the chained session alongside the rc prune).

Next: rc ~03:45Z → chained work session (run_work_next already armed 03:11Z): dump-check verification, babysit prune + phase-roll projection fix, frozen Δ_swap / swap-vs-oracle / horizon-mirror reads against the frozen 3-row table + results post; then idea4-attach-k-smoke-ladder on the free box.

Session 2026-08-09 03:17–04:0xZ (work, bounded, chained rc owner; exploit, 0 GPU-h new — the swap arm closed on its pre-registered ~1.5 GPU-h ≤ 3): subgoal-swap CLOSED end-to-end — rc=0 03:42:36Z, dump + execution oracles all green, frozen reads banked (Δ_swap −0.113 [−0.161,−0.060]; swap−oracle +0.166 [+0.127,+0.205]; table MIXED record-only: ~40% format floor / ~60% content margin), results post + chart live, queue item closed, babysit entry pruned. Babysit phase-roll projection gap fixed generically (e8ef9d5, 2 anchored oracles) + subgoal_swap_results.py landed under check.py (557). Discord read clean at every poll.

Updated 2026-08-09 04:56–08:xxZ (real date -u) — work session (bounded): attach screen ARM F ran end-to-end inside one session — launched 04:57:51Z on the steer-window default, train COMPLETE 07:42:08Z with every kill-bar passed — and the CPU window landed two pre-reg drafts + a lit slice + the rung-(c) read script.

Status: attach_F train DONE (10,000/10,000, 07:42:08Z, ~10.2 GPU-h train; probe 9.3798@10000 vs bar 10.1652 — all three boundary judgments PASS, F ends +2.21 above the phase-1 matched curve, inside the +3.0 band; vram 19.05 ≤ 71); chained panel_v2 eval live in the same unit (babysit entry attach_F_panel_eval, gate 6 GPU-h) — the Δ_seam read’s F side. K launches when the box frees (K_MEM_READY=1 BATCH=12 BACKWARD_CHUNKS=6; EXTRA_GPU_HOURS recomputed from F actual at launch). Local GPU free.

Steering: none (reads clean at boot 04:56Z and at every babysit poll through 07:43Z; steer window closed into its named default at launch — posted 04:42Z, no owner response).

Done: (1) arm F launched + babysat to completion (e762749): box synced to HEAD (perf subset now on box), unit fontaine-attach-f via run_detached, babysit entry armed, first-poll util+rate check (0.93 s/step, ~73% util — input-side headroom recorded, recipe pinned by the matched-arms rule, not touched); rate gate PASS 05:05Z (50.3 ≤ 70, full 10k, no downshift); kill-bar judgments at 5000/7500/10000 all PASS; async-save first-real-run validation PASSED at step 1250 (captured 1.3 s, published 14.0 s behind the boundary — the e3bdc93 caveat closed; 8 checkpoints, all clean). Babysit F entry’s 30 GiB floor corrected to 12 (trunk-scale value, wrong for a frozen-trunk arm). (2) #20 actckpt lineage-flip pre-reg DRAFT (e762749): 4-rung box ladder, perf-only scope (eff-48/B12 frozen), ADOPT iff r2 ≤ 1.02·r0 AND peak ≤ 63 GiB, ≤ 2 GPU-h; execution item blocked on a scheduled fresh AR-trunk launch. (3) Lit slice + papers page same session (25abe07): Hy-Embodied-0.5-VLA 2606.14409 (papers/hy-embodied-stack.md) — FlowPRO preference RL banked as the weight-space pole of the #16 post-SFT menu (retention-unmeasured caveat loud), H=50 Bézier chunk-stitch deployment lever, #4 joint-pole ledger entry under APT’s condition; dup-check caught VLAFlow already covered before a duplicate page was written. (4) #6 rung-(c) masked-contrast pre-reg DRAFT (d5568bf, queue-audit win: the item sat blocked though (b′)+swap had met its opening condition) + read script pre-data (a7693b1, mcselect_results.py = frozen reads + the producer’s dump contract, oracle 10 abort branches, check.py 559) + decode-mechanics amendment (6ad5763, caught by the read-script landing: MAE comparability needs per-candidate decodes; cost re-pinned ~2–2.5 GPU-h ≤ 4 gate). (5) posts/index.md drift fixed (2 missing 08-09 posts).

Next: queue_cli.py next → the eval finishes → launch K (this session if the box frees before hard-kill, else the chained next session; run_work_next armed) → Δ_seam frozen read (attach_seam_results.py) after BOTH arms → stage-2 decision. CPU: idea6-mcselect instrument (design note banked on the queue item). Boundaries: panel_v2 eval ~08:2x–08:4xZ; K ~10k × ~2.6 s/step ≈ 7.3 h train after that.

Updated 2026-08-09 08:14–1x:xxZ (real date -u) — work session (bounded): rung (c) went design-note → instrument → finalized pre-reg → live run → FROZEN READ inside one session, and the verdict is ANTI-SELECT — the zero-training scorer family is CLOSED for this trunk. K’s cost gate passed for the full 10k in the background.

Status: attach_K (box, unit fontaine-attach-k): COST GATE PASS 08:18:50Z — median 3.729 s/step × 10k × 4 GPU + 17 extra = 58.4 ≤ 70 GPU-h, FULL 10k, no downshift (the smoke’s 5.675 carried warmup; the downshift checklist is retired). Step ~1660 at the 09:53Z poll, 3.8 s/step, vram 59.07 ≤ 71, probe 15.92@500 → 13.08@1000 → 13.01@1500 (record — kill-bars bind at ≥5k: 12.64/11.64/10.17), CE-health aux ~2.59–2.62 flat. Endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read. Local GPU free (mcselect COMPLETE 10:20Z, ~1.1 GPU-h of the 4.0 gate).

Steering: none (reads clean at boot 08:14Z and at every babysit poll through 10:2xZ; the owner’s 08:07Z “What’s arm F?” was answered in-channel by the previous session at 08:10Z).

Done: (1) #6 rung-(c) instrument end-to-end (5181d8e): --subgoal-mode mcselect in bijou.eval — banked-candidates injection (no in-run sampling), per eligible candidate a conditioned greedy decode with ActionCaptureStep capturing the decode’s OWN action-phase logits (no re-forward, no drift vs the executed decode)

• a teacher-forced planner-less reference forward over the decoded ids against one snapshot/restored masked prefill; KL(p_cond‖p_masked^{1/τ}) float64 over the grammar-legal set; dump mcselect:kl/cand_pred/pred_masked + report τ/sha echo, exactly the read script’s pre-data contract. Oracles green: planted-informative KL fixture with exact hand arithmetic, τ→∞ ⇒ log|legal|−H(p_cond) exact, decode-vs-teacher-forced identity + capture-off byte-equality on the real tiny decoder, CLI flag matrix (15 tests); mcselect_live_oracles.py (9 abort branches selftested); check.py

574. (2) 12-row real-checkpoint smoke BEFORE the launch — full pipeline rc=0, contract keys/shapes/NaN==eligibility verified, 1.4 s/frame measured; the smoke caught a latent report-stage KeyError (per-dataset sort keyed the never-run bare bijou row in subgoal modes) that had silently cost the rung-(b′) q4 run its HTML — fixed. (3) Pre-reg FINALIZED pre-launch: immutability stamp, candidates sha256 8175624e… pinned, oracle-3 comparator amended to the rung-(a) amendment-1 matched-composition convention before any data. (4) Launcher eval_ar100k_mcselect_q4.sh (sha pins + pre-launch oracle re-runs + staged abort-grade chain); babysit entry live → pruned at completion. (5) attach_K babysit boundary rewritten at the gate verdict (downshift branch retired). (6) RUN COMPLETE 10:20Z + FROZEN READ same session (results): ANTI-SELECT — (mc − self) +0.31317 CI95 [+0.19962, +0.42894], the harder strike vs SC’s +0.210; capture fraction −1.73, late-horizon +0.385 (the ceiling’s slot, inverted), oracle agreement chance-level at 66% active picks. Kill rule executed: the zero-training scorer family CLOSES for this trunk; the (b′) ceiling stands (−0.250 vs bare) — the gap is a scorer gap, twice measured. Live-oracle chain caught one instrument bug post-run (subset_rows triple-join vs the pre-identity-column banked baseline — fixed to the sdr index-join, selftest re-green, then ALL GREEN; pred_masked flip count 1207/4301 reproduced the amendment-1 composition figure exactly). Post-mortem follow-up queued (idea6-mcselect-postmortem, record-only, banked dump). (7) Lit slice (standing allocation, scoring window): ActionX deep-read + papers page same session (page) — the F-then-joint rung’s second same-shape citation (+38 LIBERO-Long for supervised-expert-pretrain → full joint unfreeze over joint-from-scratch); does NOT re-rank F-vs-K (no matched ablation); dup-check win: LBYL 2607.03751 already covered.

Next: queue_cli.py next → attach_K endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read at matched endpoints → stage-2 decision (unblocks f-then-joint draft, now double-cited). K probe kill-bars first bind at step 5000 (~13:0xZ). CPU window (next session): idea6-mcselect-postmortem (record-only, banked dump; wanted before any learned-verifier pre-reg opens).

Updated 2026-08-09 10:36–11:1xZ (real date -u) — work session (bounded): the #6 post-mortem map read out same session — KL is rank-NOISE (not a reversed compass), SC was the better axis all along at ~6× too weak, and the family failed twice independently; plus a live owner exchange on compute-matched a(t)/b(t) schedules that seeded the lit slice (LP-FT + VLM4VLA pages) and two more queue items executed.

Status: attach_K healthy at the ~11:06Z poll — step 2780/10k, loss 3.20, 3.817 s/step (endpoint ~18:3xZ holds), vram 59.07 ≤ 71; probe 11.67@2000 → 12.42@2500, an uptick — still under the first kill-bar 12.6394 which binds only at ≥5k (~13:0xZ), watch item for the next poll. CE aux flat. Local GPU free.

Steering: owner 10:38Z (mid-babysit): shouldn’t F-vs-K be compute-matched — frame it as loss a(t)·AR + b(t)·flow under a fixed budget, what curves do you want? Answered in-channel 10:48Z (two posts): K pays ~4.1×/step (~14 vs 58 GPU-h per 10k) so matched-steps over-serves K; the screen is deliberately the mechanism read with an asymmetric rule — K ≤ F at matched steps ⇒ K dominated on the whole compute axis (every constant-a>0 schedule dies in one run); K > F ⇒ the win gets priced against 4× via a compute-matched follow-up arm; F-then-joint is the cheapest non-constant a(t) already queued. Owner 10:40Z: taps design 👍 (ack’d). No further replies through 11:0xZ.

Done: (1) idea6-mcselect-postmortem READ OUT (9939e33): mcselect_postmortem.py (reuses mcres/bbr/bijou scorers verbatim; oracle: planted monotone fixture exact hand arithmetic + 6 abort branches) → analysis json + raw sidecar npz + dated addendum with 2 dark-mode charts on the results post. THE MAP: per-row Spearman(KL, err) +0.012 [−0.005, +0.029] (rank-noise; oracle-best UNIFORM on the KL axis, 0.498 vs 0.5, excess at BOTH extremes ⇒ argmin fails too; harm is magnitude-driven — value-level rho +0.126, winner’s curse); SC −0.030 [−0.046, −0.014] right-signed but ~6× too weak for an argmax (oracle-best at SC-top 30.1% vs 12.6% null); axes mutually uncorrelated (+0.032) — two independent failures. Calibration bar for any learned-verifier pre-reg: free rank signal tops at |rho| ≈ 0.03 toward the real −0.250 ceiling. #6 escalation stays CLOSED. (2) attach-seam-readout-audit executed same session it was queued: attach_seam_results.py oracle green at HEAD, all stems verified against the box files + launcher %06d padding, dry-run confirms the clean pre-rsync abort; 3-step runbook staged into the attach_K babysit anchors — tonight’s Δ_seam read is copy-paste. (3) lit-unfreeze-schedules executed (owner-steered slice, 2 papers pages): LP-FT (2202.10054 + NTK 2405.16747 — f-then-joint’s THIRD citation, first with matched frozen control + the feature-distortion theorem; compute-Pareto case for step-function a(t); explicitly silent on F-vs-K since K’s stop-grad blocks the distortion channel) and VLM4VLA (2601.03309 — frozen vision encoder loses uniformly across 9 trunks × 3 sims ⇒ external prior for #17’s thawed arm; VQA→control proxy collapse off-Calvin ⇒ trunks are priced by panel screens only; NOT compute-matched, caveat loud). index/SUMMARY/ideas #4 + #17 hooks updated.

Next: queue_cli.py next → attach_K kill-bars first BIND at 5000 (~13:0xZ; probe uptick watch); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision (unblocks the triple-cited f-then-joint draft). Queue depth 2 (lit-radar-hooks-17 executable any GPU-busy window).

Session 2026-08-09 03:50–04:1xZ (tick; 0 GPU-h): owner question 03:28Z (60k reports linkage + hub upload) had been cursor-consumed unanswered by the prior session — caught via the history check and answered: hub YES (re-verified), reports page NO (real gap). Fixed same tick: three 60k jsons pushed to the Space reports/, reports.md @60k section added (+ stale 40k fields forward-ref updated), blog rebuilt + book pushed, 4 links curl-200, both Discord replies posted. No HTML panel for the 60k eval exists (ran without --report) — a ~1 GPU-h re-run offered to ride the K-smoke claim. Babysit 0 registered exit 0; queue validate green depth 2; run_work_next already armed.

Session 2026-08-09 04:30–04:5xZ (tick, held through the verdict window; +~0.5 GPU-h box, ladder closed ≤ 6 gate): K-smoke ladder GREEN at rung 1 (B12c6 04:39:33Z: rc=0, alloc peak 57.34 ≤ 71 GiB, 5.675 s/step — full batch, no downshift; k_mem_ready synced local). Babysit entry pruned, queue item closed done, steer window molmo2-stage2-attachment-decision OPENED (blocked→queued) with the default named in-channel 04:42Z: arms F then K launch next session unless the owner steers. Prior session’s uncommitted queue state folded in. Discord read clean; no reactions.

Session 2026-08-09 04:56–08:xxZ (work, exploit; +~11–12 GPU-h box — attach_F train 10.2 + eval in flight): arm F end-to-end — steer window closed into its default, launched 04:57:51Z, rate gate PASS (50.3 ≤ 70), all three kill-bars passed, train COMPLETE 07:42:08Z, async saves live-validated (1.3–2.1 s captures), panel_v2 eval chained. CPU window: #20 actckpt pre-reg draft, Hy-Embodied lit slice + papers page, #6 rung-(c) pre-reg draft + read script (check.py 559) + decode amendment, posts-index drift fix. K launch = the chained next step.

Session 2026-08-09 08:14–1x:xxZ (work, exploit; local mcselect +~1.1 GPU-h ≤ 4 gate — run AND frozen read landed in-session; box K live in background): #6 rung-(c) end-to-end — instrument (capture-during-decode KL, teacher-forced masked reference, pre-data contract honored exactly; 15 oracle tests + 9-branch live-oracle selftest, check.py 574), 12-row real-checkpoint smoke (caught + fixed the subgoal-mode report-sort KeyError that silently ate the (b′) q4 HTML), pre-reg finalized with sha pins, launch 09:12:36Z, complete 10:20Z, VERDICT ANTI-SELECT (+0.313 [CI +0.200, +0.429]) — the zero-training scorer family CLOSES; results post + post-mortem item queued. Lit slice: ActionX papers page (F-then-joint’s second citation). attach_K cost gate PASS 08:18:50Z (58.4 ≤ 70 — full 10k); babysit boundary rewritten, downshift checklist retired.

Session 2026-08-09 10:29–10:5xZ (tick, conversational; 0 GPU-h): recovered a dropped owner exchange — the 08:16Z KI-rationale question and the 09:53Z cross-attention follow-up had been cursor-consumed unanswered; both answered in-channel 10:36Z (KI = insulated trunk adaptation vs the moving-target cost, Δ_seam prices it; Molmo2 attach = residual taps 2,5,…,35 via adapters, not K/V export), history-diff reply-watch held through the tick, feedback memory recorded (read is consume-once — same-session replies mandatory). attach_K healthy: probe 11.67@2000, already under the 5k kill-bar. Queue validate green depth 2; run_work_next armed.

Updated 2026-08-09 11:34–11:5xZ (real date -u) — work session (bounded, chained via run_work_next): the two unread #17 radar hooks cleared — VEGA lands a THIRD pole on the vision-freeze axis (aux-injected spatial structure substitutes for unfreezing) and HyperVLA stakes the inference-efficiency pole; 2 papers pages same session, queue refilled.

Status: attach_K healthy at the 11:35Z + 11:42Z polls — step 3340/10k, loss 3.20, 3.84 s/step (endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / 4 GPUs. Probe 11.6124@3000 (best); first kill-bar 12.6394 binds ≥5k (~13:2xZ) with ~1.0 margin. CE aux flat. Local GPU free.

Steering: owner 11:43:03Z (caught on the post-session-post read): why did train/loss_action crash to ~0.2–0.3 on the current run vs >2.5 on the 40k AR run — does the field still mean AR action-token loss? Answered in-channel 11:48Z after verifying at bijou/train.py:619–624: the field changed meaning, nothing crashed — in the joint arm the loss_action slot carries the flow-matching component (regression scale ~0.2–0.3) and the AR action-token CE moves to train/loss_aux (~2.6, flat — exactly the pre-registered CE-health drift watch, matching the phase-1 curve at matched step; the babysit anchors already compare the right pair). Reply-watch held ~8 min post-answer.

Done: lit-radar-hooks-17 EXECUTED (the queued lit slice, ~25 min): deep-read both banked #17 hooks + 2 papers pages SAME SESSION per the permanent rule — VEGA (2605.10485: encoder-output cosine alignment to DINOv2-FiT3D, projector discarded at inference; beats Spatial-Forcing LLM-token alignment 67.5/30.7 vs 64.2/27.8 on RoboTwin easy/hard + 0.60 vs 0.55 real ALOHA; the frozen-FiT3D ≈ unfrozen-FiT3D probe ⇒ unfreezing pays only while features lack what control needs — banked as the vu5k readout’s interpretation lever + named cheap escalation if thawed wins; Molmo2 single-tower caveat + VGGT-teacher collapse noted) and HyperVLA (2510.04898: understand-once/execute-tiny — 0.1M generated policy per episode, 4 ms/step, 90× fewer activated params, sim-only vs 2024-OpenVLA; #17 trunk-ledger pole + #16 rig-latency existence proof + the √d generated-update normalization rule; its MSE-beats-diffusion ablation regime-bound, explicitly NOT read onto AR-vs-flow). index/SUMMARY/ideas #17 + idea-page ledger updated; new radar hook banked: Spatial Forcing 2510.12276 (3.8× training-accel claim unexamined). Queue: item closed, lit-radar-async-exec queued (FASTER + ABPolicy + DEFLECT cluster, feeds #22/#16/#12).

Next: 5k kill-bar binds ~13:2xZ (probe must be < 12.6394 — currently 11.61); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision. queue_cli.py next → lit-radar-async-exec (any GPU-busy window).

Session 2026-08-09 11:34–11:5xZ (work, bounded — explore/lit; 0 GPU-h): lit-radar-hooks-17 executed — VEGA 2605.10485 + HyperVLA 2510.04898 deep-read, 2 papers pages same session (vega-encoder- grounding, hypervla-hypernetwork-inference): VEGA = third pole on the vision-freeze axis (encoder-level 3D-aware alignment aux substitutes for unfreezing; vu5k interpretation lever + cheap escalation), HyperVLA = inference-efficiency pole (0.1M generated policy, 4 ms/step) + √d normalization rule; MSE-vs-diffusion regime-bound caveat loud. Spatial Forcing 2510.12276 banked as new hook; queue refilled with lit-radar-async-exec. attach_K healthy both polls (3340/10k, probe 11.61@3000 best, bars bind ~13:2xZ); Discord clean throughout; run_work_next armed.

Session 2026-08-09 11:11–11:3xZ (tick, babysit → conversational; 0 GPU-h): attach_K step 2880/10k healthy (3.822 s/step, vram 59.07 ≤ 71, endpoint ~18:3xZ); held through the step-3000 probe boundary — 11.6124@3000, new best: the 2500 uptick was noise, first kill-bar (12.64, binds ≥5k ~13:2xZ) has ~1.0 margin. Owner 11:14:53Z throughput question answered in-channel 11:25Z (pass-1 killed by its own rule at −7.3%/−10.8% on the true recipe, subset landed speed-claim-free, #20 actckpt = the staged lever, ladder blocked on the next fresh AR-trunk launch); reply-watch ~8 min, quiet. Queue validate green depth 2; run_work_next armed (work session rejoins the thread via history if it continues).

Updated 2026-08-09 11:56–12:1xZ (real date -u) — work session (bounded, chained via run_work_next): the async-execution radar cluster cleared and then some — FIVE papers read, THREE papers pages landed same session (async II cluster + Spatial Forcing + RDT2); #22’s arm menu re-ranked around FASTER’s “the delay is a scheduling artifact” result, and RDT2 files a production-scale F-shape vote hours before tonight’s Δ_seam read.

Status: attach_K healthy at the 11:57Z + 12:08Z polls — step 3740/10k, loss 3.21, 3.74 s/step (endpoint ~18:3xZ holds), vram 59.07 ≤ 71, liveness 7 procs / 4 GPUs. Probe 11.2033@3500 (new best); first kill-bar 12.6394 binds ≥5k (~13:2xZ) with ~1.4 margin. CE aux flat. Local GPU free.

Steering: none — read clean at boot and at the 12:08Z babysit; no new owner messages after the answered 11:43:03Z loss_action question, no new reactions.

Done: lit-radar-async-exec EXECUTED, both ride-along clauses fired (the cluster closed early, so Spatial Forcing AND RDT2 rode per the item’s own text): (1) async execution II — FASTER 2603.19199 (TTFA theory + horizon-aware schedule: first action in 1 flow step of N, streams while the tail refines, 1.29–3.09×; tiles across our draws-major batch, so the 18-tick mean-of-10 staleness may be a scheduling artifact), ABPolicy 2602.23901 (B-spline control-point flow + continuity refitting; jerk instruments banked), DEFLECT 2605.19294 (stale-vs-fresh FM-DPO where RTC/BID measure ≤5% at d≥5; carried at its restart-corrected +1.6–2.3 pp, not the +6.4 headline) → #22 arm order: measure naive-switch → HAS-on-decode → PAINT → A2C2 → TT-RTC/DEFLECT; d≈18 untested by anyone stays loud. (2) Spatial Forcing 2510.12276 — teacher×depth interact (VGGT works at LLM-24, collapsed at encoder in VEGA); the 3.8× is a fewer-steps lever (≈50k vs 150k iters, +25.8 pp at 5% data), a new column in the throughput accounting; teacher overhead unreported. (3) RDT2 2602.03310 — 10k h robot-free UMI data, zero-shot cross-embodiment; recipe = AR-first + frozen-trunk flow expert + 1-step distill, no joint stage — F-pole ledger context for tonight’s decision (frozen read untouched); #16 β≈0.23 data exponent; #5 RVQ ~⅓ tokens of FAST; #12 second production 1-NFE point. Ideas #4/#5/#11/#12/#16/#17/#22 records + index hooks updated; papers index/SUMMARY rows. Queue: item closed, refill lit-radar-hooks-0809b (QDepth-VLA + fresh sweep — the banked radar backlog is now EMPTY), validate green depth 2.

Next: 5k kill-bar binds ~13:2xZ (probe must be < 12.6394 — currently 11.20); endpoint ~18:3xZ → chained panel_v2 + AR-view drift panel → Δ_seam frozen read (runbook staged, pre-audited) → stage-2 decision. queue_cli.py next → lit-radar-hooks-0809b (any GPU-busy window).

Session 2026-08-09 11:49–12:0xZ (tick, babysit; 0 GPU-h): attach_K step 3460/10k healthy (3.799 s/step, probe 11.6124@3000 best, kill-bar margin ~1.0, binds ~13:2xZ, endpoint ~18:3xZ); Discord clean — only our own 11:48Z loss_action answer surfaced, reply-watch held to ~11:59Z via background history poll, quiet. Two integrity fixes: queue.json updated_utc future-dated 12:05Z → corrected to 11:45Z (78cace5 class), and 89 root-relative links across archive/*.md (papers/posts/journal/reports, all 404 one level deep) rewritten to ../ paths, grep-verified 0 left. Queue validate green depth 2; run_work_next armed (lit-radar-async-exec next).

Updated 2026-08-09 12:36–12:5xZ (real date -u) — tick (babysit → conversational): owner steering burst, three messages in 10 min — attach_K KILLED on owner instruction (cost call, ~4× F per step), a docs-modernization pass prioritized ahead of an owner main-rebase, and a brand-new top-priority run spec: molmo2 from base 4B, 100k steps, vision unfrozen from step 0, AdamC optimizer (implement first, parameter sheet for approval before launch).

Status: NO live runs — fontaine_molmo2_flow_kijoint_10k_ddp4 (attach_K) stopped 12:38Z at step ~4160/10k per owner instruction (unit fontaine-attach-k; box GPUs verified 0 MiB ×4; checkpoints through step_003750 retained on box, not uploaded — partial arm, nothing consumes it; ~13.6 GPU-h spent 08:01–12:38Z). Probes were healthy at kill (10.9664@4000 best, ~1.7 under the 5k bar) — this was a COST kill (3.74 s/step vs F’s 0.92), not a gate. Local GPU free. Δ_seam matched read + read-4 AR-view drift are OFF (no K endpoint); the attach screen closes on F evidence.

Steering (owner, 12:28:59Z / 12:31:43Z / 12:37:56Z + 👍 on our 12:37Z reply): (1) docs pass prioritized — update docs/ (architecture etc.) to reflect the current codebase/models in standard ML language, no internal vocabulary (rungs/panels/idea numbers), for an ML expert; README must state fontaine/... = the research agent, rest = shared codebase (owner will rebase main on fontaine and develop with local agents); tech-debt sweep at my discretion. (2) kill attach_K — “way too slow per step”; executed 12:38Z. (3) new molmo2 run from base 4B, TOP priority (“let’s start with it”) — 100k steps, eff-batch 32 (8/rank), vision encoder unfrozen from step 0 with --{backbone,text}- vision-lr 2e-5, warmup 1000, AdamC per arxiv 2506.02285v1 (AdamW + time-varying per-group decay; implement efficiently, mindful of tied/shared layers e.g. Gemma lm_head; read the owner’s shared conversation claude.ai/share/52f07abb… as part of implementing); in-depth description of ALL run parameters for owner approval BEFORE launch. All three acknowledged in-channel (12:37Z + 12:40Z posts). ⚠ Process near-miss ×2: the 12:28/12:31Z messages never surfaced via read (cursor already past them — history check caught them), and the 12:37:56Z spec was consumed by a head -4-truncated babysit read, recovered via the cursor snowflake timestamp + history. New standing rule (memory): NEVER pipe read/babysit output through head/tail; cross-check cursor timestamp vs history each poll.

Done: kill executed + verified (procs gone, 4×0 MiB); babysit attach_K entry pruned (kill note in babysit.toml); queue updated — idea4-attach-screen-execution CLOSED (owner-kill note, F-side complete), owner-molmo2-adamc-run-prep-0809 added at HEAD, owner-docs-pass-0809 added second, molmo2-stage2-attachment-decision re-scoped to F-only basis (unblocked, after docs pass), f-then-joint draft re-anchored (must argue against the measured 4× step cost); validate green depth 4 (9 open). Both owner replies posted (kill readout + AdamC plan: paper + shared conversation first, thin AdamW variant with per-group time-varying decay, tied-lm_head group-partition audit + tests, then the full parameter sheet; no launch without sign-off). run_work_next armed.

Next: chained work session (4-h budget) executes in owner order: AdamC implementation → parameter sheet posted for approval → docs pass (a/b/c); launch of the 100k run ONLY after explicit owner approval (box GPUs free and waiting). Then stage-2 memo (F-only basis) + lit-radar-hooks-0811a in any gap.

Updated 2026-08-09 13:42–14:1xZ (real date -u) — work session (bounded, one item): the #4 stage-2 attachment decision is CLOSED — frozen default stands, memo posted from banked artifacts — and adamc_100k survived its microbatch-1 first backward and is running healthy at full utilization.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3, 13:40Z, chunks 8 / microbatch 1) — step ~480/100k at the 14:06Z babysit, GPUs 97–100% ×4 (first-poll starvation check clean), 2.62–2.75 s/step, vram alloc peak 70.4 vs the 77 bar, loss 16.33@20 → 7.59@160 falling smoothly through warmup, CE-aux 1.17, grad-norm 283→31 (record-only AdamC watch). Banners verified: AdamC λ=1e-5 partition 4074.7M/2.6M/0.6M, E1 dataset gate exact. Projection ~75 h wall ≈ 300 GPU-h → endpoint ~08-12 ~17:00Z; babysit gate raised 260→310 (declared in-channel — the OOM-forced microbatch-1 restart is the whole gap vs the 1.7–2.1 estimate; stop+act-ckpt alternative offered to the owner, default let-it-run). First async-save line owed at step 5000 (~17:2xZ).

Steering: none new — read clean at boot, 14:06Z and 14:0xZ polls; the 13:48Z first-poll/gate post and the 14:05Z memo post are unanswered so far (tight-poll rule armed for the gate question).

Done (e4b0ba5): stage-2 attachment decision memo posted (post) — frozen default ADOPTED for the Molmo2 trunk class; KI-joint closed-unmeasured (honesty flag up front: no Δ_seam CI exists, K was owner-killed at ~4160). Basis: F panel 9.4157 vs state-copy 11.7639 (2× the decisive bar), 8 matched probe evals K−F mean +0.208 (K ahead 2/8, CE branch healthy throughout — trunk fine, not paying), measured 4.11× step cost, RDT2/Qwen-VLA frozen-first votes; Wall-OSS reading recorded. Probe-curve chart landed (attach_screen_probe_chart.py, eval-report dark theme). Priced residuals: Δ_seam@3750 rescue read ~2.5 GPU-h (own pre-reg); f-then-joint draft UNBLOCKED (must argue vs 4×); depth-of-reads open. Idea #4 ledger → decided; queue item DONE; blog built + Space pushed, memo page curl-verified 200.

Session 2026-08-09 12:12–12:2xZ (tick, babysit; 0 GPU-h): attach_K step 3800/10k healthy (loss 3.10, 3.78 s/step, probe 11.2033@3500 best, vram 59.07 ≤ 71; 5k kill-bar margin ~1.4, binds ~13:2xZ, endpoint ~18:3xZ). Discord clean — read empty, history nothing new after our 12:12Z session post, no new reactions. Queue validate green depth 2 (8 open); run_work_next armed (lit-radar-hooks-0809b next: QDepth-VLA + fresh sweep). Stable stretch → exited rather than held; next tick catches the 5k crossing.

Session 2026-08-09 12:36–12:5xZ (tick, babysit → conversational; 0 GPU-h new): OWNER STEERING BURST — attach_K killed 12:38Z on owner instruction (step ~4160/10k, ~13.6 GPU-h spent, cost call: 3.74 s/step vs F’s 0.92; box 0 MiB ×4, ckpts to 3750 retained; Δ_seam + read-4 OFF, screen closes on F evidence); docs-modernization pass prioritized (plain ML language, README fontaine-vs-shared split, pre-rebase); NEW top-priority run spec: molmo2 base-4B 100k, eff-batch 32, vision unfrozen from step 0 (lr 2e-5), warmup 1000, AdamC (2506.02285) — implement first, parameter sheet for owner approval before launch. Both replies posted; 👍 on the kill/docs reply. Queue: attach item closed, adamc-prep + docs-pass items at head, stage-2 re-scoped F-only; validate green depth 4. Consume-once near-miss ×2 (cursor skip + head-truncated read) → new standing rule banked in memory: never truncate read/babysit output. run_work_next armed (AdamC first, docs pass second).

Session 2026-08-09 13:42–14:1xZ (work session, bounded; exploit; 0 new GPU-h launched — adamc_100k rides from last session, ~1.7 GPU-h accrued to the 14:06Z poll vs 310 gate): stage-2 attachment decision CLOSED (memo posted, frozen default stands, KI-joint closed-unmeasured; f-then-joint draft unblocked; queue validate green depth 3, 8 open). adamc_100k survived the microbatch-1 first backward (launch 3): 2.62–2.75 s/step, vram 70.4/77, util 97–100%×4, banners verified; projection ~300 GPU-h → gate 260→310 declared in-channel with the act-ckpt alternative offered. Discord: first-poll facts + memo posted; no owner traffic. run_work_next armed.

Updated 2026-08-09 14:11–15:0xZ (real date -u) — work session (bounded, one item): the F-then-joint pre-reg DRAFT is posted (#4’s escalation, the queue head), the standing lit slice landed two Papers pages (SEAM + Robot Critics), and adamc_100k is healthy through step 1000 at full utilization.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0 ×2 this session, 8 procs, GPUs 97–98% ×4 at the 14:5x poll, step 1000 (probe cadence 500; first probe banked eval 31.2959@500 — no bar binds before step 5000), rate 2.56–2.62 s/step steady between probe evals, vram alloc peak 70.4 vs the 77 bar, cumulative 3.3/310 GPU-h. Next boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel); kill-bar comparison binds at eval@2500 vs @10k (~08-10); endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report).

Steering: none — read clean at boot and both babysit polls; last owner message remains the 13:24Z λ override (actioned). The 13:48Z gate question (let-run vs act-ckpt refit) stays unanswered; declared default (let it run, gate 310) governs. ⚠ Process note: babysit output was piped through tail/grep TWICE this session (standing rule violation, consume-once cursor) — history checks confirmed nothing was missed both times; the rule is re-armed, no filtered babysit/read calls.

Done (a627a0c): (1) F-then-joint pre-reg DRAFT posted (draft) — J (trunk unfrozen, NO stop-grad, CE rider continuing; warm-start from the banked F@10k expert = APT’s Stage-1 capital) vs F2 (frozen continuation control), matched +5k eff-48, fresh shared seed 2; primary Δ_joint = J@+5k − F2@+5k paired CI, conditional 10k extension only on a negative CI, adoption bar −0.3, drift band 0.3 vs 60k 5.8602; committed ~32 GPU-h ceiling 35 (extension → global 70), J’s rate anchored on K’s measured 3.782 s/step; the 4×-cost burden argued up front (bounded final phase, not a lineage). Code audit: --init-from covers the warm-start; instrument gaps named (composite materializer, narrowly-scoped naive-joint guard escape, AR-view compat, J-config memory smoke) → split to idea4-fjoint-rung-finalize-exec (launch owner-gated). (2) Lit slice (queue item cleared): SEAM 2607.04609 deep-read — closed-form λ(1−t) boundary steering, +1% cost, jerk −28%, #22 arm order updated (SEAM cheapest, PAINT stays async-robust), and a FREE hook queued (boundary-incompat-read-npz: tail-vs-head disagreement on banked panel npz, zero GPU — a null closes #22’s bridging direction for our stack); Robot Critics 2606.21572 skim-to-place — trained-critic pole placed and parked. Radar refilled (lit-radar-hooks-0812a: Freq-Aware FM 2606.20135, VISTA 2606.04708, latent-action FM pair). Queue validate green depth 4 (9 open); blog built + Space pushed, both pages + draft curl-verified 200.

Next: queue_cli.py next pointer → boundary-incompat-read-npz (CPU, free read) or the fjoint instrument (CPU part of idea4-fjoint-rung-finalize-exec) or docs-pass-followups-0809 / lit-radar-hooks-0812a — all CPU, in the run’s shadow; queue.json is canonical. adamc_100k boundaries: async-save quote ~17:2xZ (this session’s chained successor catches it), eval@2500-vs-@10k comparison ~08-10, endpoint ~08-12 ~17:00Z → chained panel → leaderboard row + grad-norm chart.

Session 2026-08-09 14:11–15:0xZ (work session, bounded; exploit+lit; 0 new GPU-h — adamc_100k rides, 3.3/310 at the 14:5x poll): F-then-joint pre-reg DRAFT posted (a627a0c; J-from-F@10k vs F2 control, +5k matched, ceiling 35/70; finalize-exec queued, owner-gated) + lit slice 2 pages (SEAM → free boundary-incompat npz read queued; Robot Critics parked). Queue depth 4 (9 open). Two babysit-truncation near-misses, history-verified clean, rule re-armed. run_work_next armed.

Session 2026-08-09 14:34–14:4xZ (tick, babysit; 0 GPU-h new — adamc_100k rides, 3.6/310): run healthy at step 1100 — probe@1000 24.4834 (from 31.30@500), loss 5.30 falling, 8 procs, ~75 GiB ×4; window 19.7 f/min attributed to the in-window eval@1000. Discord: read = our own lit-slice posts only, history no reactions, gate question still open (default governs). Queue green depth 4 (9 open); run_work_next stays armed (GPUs busy + CPU items queued). Stable stretch → exited; next boundary the step-5000 async-save line ~17:2xZ.

Updated 2026-08-09 14:34–14:4xZ (real date -u) — tick (babysit): adamc_100k healthy through step 1100 — probe@1000 banked at 24.4834, down hard from 31.30@500.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0, 8 procs, ~75.1–75.3 GiB ×4, step 1100 at the 14:34 poll, window 19.7 f/min (probe eval@1000 inside the window; steady neighbors remain 2.56–2.62 s/step). Probe@1000: eval_chunk_mae 24.4834, train_mae 25.5791 — falling fast out of warmup, already under the 25 sustained-×3 bar that only binds after step 5000. Loss 5.30@1100 falling smoothly. Cumulative 3.6/310 GPU-h. Next boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel); kill-bar comparison binds at eval@2500 vs @10k (~08-10); endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report).

Steering: none — read surfaced only our own two posts (the lit slice + its typo fix); history -n 5 all our own, no reactions. The 13:48Z gate question (let-run vs act-ckpt refit) remains unanswered; declared default (let it run, gate 310) governs.

Done: babysit poll + log-level anomaly scan (probe@1000 pulled from the box log — the CLI window rate attributed to the in-window eval, grad-norm watch unremarkable); queue validate green depth 4 (9 open); run_work_next left armed (GPUs busy + CPU items queued).

Next: chained work session → boundary-incompat-read-npz (free npz read) or the fjoint instrument CPU part or docs-pass-followups-0809 / lit-radar-hooks-0812a; queue.json canonical. adamc_100k boundaries unchanged: async-save quote ~17:2xZ, eval@2500-vs-@10k comparison ~08-10, endpoint ~08-12 ~17:00Z → chained panel → leaderboard row + grad-norm chart.

Updated 2026-08-09 15:59–16:1xZ (real date -u) — tick (babysit): adamc_100k healthy through step 3000 — probe@2500 banked at 14.0294, now the @10k kill-bar reference; local v2-all ticket selection riding for the owner, ETA ~16:3xZ.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE (launch 3) — babysit exit 0, 8 procs, ~75.1–75.3 GiB ×4 vs the 77 bar, step 3000 at the 16:00 poll, window 19.9 f/min steady, 9.4/310 GPU-h. Probe trajectory 31.30@500 → 24.48@1000 → 16.87@1500 → 14.03@2500 (banked at the 15:52 poll, quoted in-channel with the ticket post). LOCAL GPU: fontaine-ftrig-ticket64-v2all.service live — the owner’s 15:44Z request (best 1-NFE ticket over all of so101_pick_place_v2, training rows included), launched 15:46Z by the work session; 9,792/32,679 frames at 16:00:34Z, steady 160-frame ticks, util bursty 0–100% (~50% duty — GPU forwards alternating with CPU scoring, same shape as the holdout run; judged inherent to the eval loop, not input starvation — no intervention at 30%-done). ETA ~16:30–16:40Z → plans/ticket_ftrig4k_rigv2all_winner.npz + table owed in-channel (vs ticket 59 holdout winner and ticket33). Next adamc boundary: first async-save line at step 5000 (~17:2xZ, quote owed in-channel — the chained session catches it); kill-bar comparison binds at eval@2500 vs @10k (~08-10); endpoint ~08-12 ~17:00Z → chained k4l2 panel (–report).

Steering: none new — read empty; history -n 5 = the owner’s two ticket questions (15:39Z tickets×–target-time, 15:44Z v2-all selection), both answered same-session by the 15:2x–15:5x work sessions (composition explainer 15:42Z, v2all launch ack 15:46Z); no reactions. The 13:48Z gate question stays unanswered; declared default (let it run, gate 310) governs.

Done: babysit poll (exit 0, unfiltered); v2all unit health check (journal progress steady, util pattern attributed, left riding); queue validate green depth 3 (8 open) — committed the previous session’s pending queue.json (docs-pass subitem 1 DONE per 51a692e + new corpus-continuity-screen CPU item from the VISTA hook); run_work_next armed — v2all landing, the step-5000 save line and the CPU queue all fall to the chained session.

New projection: endpoint ~05:1xZ 08-10 → panel_v2 → Δ_capacity read ~06:3xZ. Note: the old run’s probe 16.46@500 row persists in the reused jsonl — ignore rows predating 21:03Z.

Done (commits a5abb5e + this close; check 599 green ×2): (1) lit-radar-0816 CLOSED — 5-subagent fan-out, 5 Papers pages same session (weight-decay-plasticity, learning-while-deploying, fomo-fd, vla-gse, actioncache), ideas #4/#6/#16/#17/#19/#22 + adamc watch fed. Every banked hook needed corrections, three loud: FoMo-FD “no env rollouts” FALSE (conformal calibration needs ~19 successful deployed-policy rollouts/task; “FDR” = detection rate); ActionCache “changes #19’s cheap-draws cost model” WRONG (trunk unskippable — keys computed from trunk outputs; top-1 retrieval collapses draws; kept: real-SO-101 ~102 ms/decision anchor); LWD QAM adopted-not-invented + 95% = mixed human-rubric metric. Refill sweep → lit-radar-0817 queued (2 dup catches: 2607.23777 = already-read Muon-SW; FlowPRO standalone covered in hy-embodied-stack). (2) MolmoAct2 deep dive (2026-08-09-molmoact2-deep-dive.md, 4 research tracks, Space 200 ×6): backbone IS Molmo2 → Molmo2-ER (+6.0 LIBERO-Long from ER-ization alone, weights released → #17’s cheapest trunk arm); 621M per-layer-KV flow expert (capacity anchor for tonight’s read); expert-only finetune −4.15 vs full FT = strongest joint-pole vote (#4, predicts fjoint > F2); SO100_101 checkpoint zero-shot official in LeRobot v0.6 (12.1 GiB bf16, joint-remap gotcha), expert-only FT 16.5 GiB single-GPU; repo_list.json mechanizes the survey’s corpus diff (#9). (3) tiny10k OOM recovery (Status). (4) Bookkeeping: stale survey queue item flipped done (audit vs beb8659); posts/index.md drift fixed (5 missing 08-09 entries).

Next: queue_cli.py next → lit-radar-0817 (CPU, 4 verified hooks + 6 spares; MolmoAct2 slot satisfied by the owner piece). tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity readout session (now with MolmoAct2’s 15.5% expert-ratio anchor). adamc endpoint ~08-12 ~17:00Z → chained k4l2 panel. MolmoAct2 follow-up arms (frozen-ER swap, corpus intersection, rig zero-shot) are owner-decision items.

Session 2026-08-09 20:47–21:1xZ (work, bounded; real close 21:15:31Z — the note’s original 21:5x stamp was a hallucinated clock, corrected by the 21:17Z tick; ~0.4 GPU-h lost to the tiny10k host-RAM OOM + relaunch riding to ~05:1xZ ≈ 9.5 ≤ 15 gate; adamc rides 30.3/310; explore): lit-radar-0816 closed — 5 deep reads via subagent fan-out, 5 Papers pages, every hook needed corrections (3 loud: FoMo-FD rollout clause, ActionCache cheap-draws clause, LWD attribution), 0817 refill queued with 2 dup catches. Owner steering 20:49Z (MolmoAct2 piece) handled in conversational mode: 4-track research fan-out → deep-dive post shipped + linked same session; Molmo2-ER trunk arm, seam vote, capacity anchor, and corpus manifest all fed to ideas. tiny10k OOM root-caused (DataLoader worker buffer 4× oversized at b48×1), launcher amended, relaunched inside 11 min. adamc probe @9500 = 10.63 new run-best. Commits a5abb5e + close; check 599 ×2; Space pushed, 6 new pages 200.

Session 2026-08-09 21:17–21:2xZ (tick, babysit; 0 new GPU-h — adamc rides 30.5/310, tiny10k ~1.1/15): both runs healthy. adamc’s step-10,000 pre-registered kill line JUDGED PASS (probe 10.80@10000 vs its own @2500 = 14.0294, clear by 3.23; run-best 10.63@9500 stands); the 5.6 st/min babysit window was the @10000 boundary (async save captured 21.2 s + probe eval), rate re-verified ~22 st/min right after. tiny10k host RAM 122/221 used, 98 free — the workers-10/prefetch-2 amendment holds. Owner 👍 on the 21:03 recovery post recorded (reaction protocol). Clock-hallucination audit: the 20:47 work session stamped 21:45/21:5x at a real ~21:15 — queue.json updated_utc was future-dated 30 min; corrected there + in now.md. Queue green depth 3 (9 open); run_work_next armed (21:16) for lit-radar-0817.

Session 2026-08-09 21:24–21:4xZ (work, bounded; 0 new GPU-h — adamc rides 31.8/310, tiny10k 1.4/15; explore): lit-radar-0817 closed in ~15 min wall clock — 4 deep reads + refill sweep as 5 concurrent subagents, 4 Papers pages (armnetbench, safecast, reflex, legato, compression-gap; MolmoAct2 slot pre-satisfied), every hook needed corrections (3 loud: ArmnetBench label-count + missing checkpoints, SAFECAST not-offline + sub-coin-flip on flow policies, Legato smoothness→completion-time). Ideas #6/#9/#16/#19/#22 fed; #6 gains a go/no-go gate (probe separability vs ArmnetBench labels), #19 a cost-model split (draws share one trunk prefill). Refill: 12/16 candidates were corpus dups (pool drying — instrument + angle notes in the 0818 item); 4 clean hooks, no spares. tiny10k relaunch sanity: probe @500 = 16.78 vs pre-OOM 16.46. One self-caught future-dated stamp corrected. check 599; Space pushed.

Session 2026-08-09 21:43–21:5xZ (tick, babysit; 0 new GPU-h — adamc rides 32.3/310, tiny10k 1.5/15): quiet green tick. adamc step 10,640 @ 23.1 st/min, probe 11.06@10500 mild uptick above the 10.63@9500 run-best (recede-precedent class, record-only). tiny10k step 800 @ 20.2 st/min on projection; host RAM 134/221 used, 86 GiB available — amendment holds. No steering (read = own post only, no new reactions). Queue green depth 3 (9 open); run_work_next already armed at 21:43 for lit-radar-0818.

Previous update 2026-08-09 21:47–22:1xZ (real date -u at write: 22:03) — work session (bounded): lit-radar-0818 CLOSED — 4 Papers pages same session via 5-agent fan-out; all four banked hooks needed corrections AGAIN (one was our own corpus laundered back at us); the new-angles refill sweep fixed the pool — only 2/16 dups vs 0817’s 12/16, first spares banked in days.

Status: fontaine_molmo2_adamc_100k_ddp4 LIVE — babysit exit 0 (21:58), step 10,960, 22.4 st/min, 33.2/310 GPU-h, vram 75.3 ×4 vs 77. Probe ladder unchanged (run-best 10.63@9500; 11.06@10500 recede-precedent class). Post-kill-line cruise, endpoint ~08-12 ~17:00Z. fontaine-tiny10k LIVE local — step 1,120, 22.4 st/min, 1.8/15 GPU-h; probe 14.52@1000 (16.78@500 → 14.52, descending on schedule; F@1000 anchor n/a — ladder comparable from @5000). Endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read ~06:3xZ.

Done: lit-radar-0818 CLOSED — 4 Papers pages (athena, probeact, qwen-robotmanip, plasticity-at-scale). Corrections, all four: ATHENA is rollout-anchored (NOT offline curation), corpora 9.3h sim / 6.9h real, code link dead — but their demo-length heuristic landed BELOW random on real tasks (a warning for naive quality gates on our 229h) and cross-model transfer licenses proxy-policy scoring (→ #9 parked “offline-ATHENA” note). ProbeAct hook wrong on both clauses (position regressor on 50k sim-oracle labels + hand-coded kinematic rules, zero detection metrics) — survives: trunk decodes object position R²=0.968 while flow cells probe below coin-flip elsewhere → #6’s ArmnetBench gate gains a trunk-tap arm (spatial pooling, shallow-mid sweep). Qwen-RobotManip “38,100h” is ~65% re-rendered human video (~7,800h real teleop ≈ 34× us, not 166×), nothing released — survives: 5-stage fully-offline state-action filter (81% of RoboMIND-UR excluded as broken proprioception) → #9 cheapest arm = DA+jerk pass over our corpus; #17 fourth attachment pole + benchmark-saturation seconds VLM4VLA. Plasticity-at-scale’s WD clause was a citation of 2602.11137 — our own corpus resold as a new hook; durable export is negative (dormant-unit/param-norm/ attention-entropy proxies all fail; behavioral fixed-budget probes only; record-only for the adamc watch). Ideas #6/#9/#17 + index hooks fed; Radar 0818/0819 tables in papers/index; SUMMARY.md entries added (0817’s 404 class pre-empted). Refill: fresh sweep on the 4 mandated new angles → 16 abs-verified candidates, only 2 corpus dups by local grep → lit-radar-0819 queued with 4 priority hooks (Squint SO-101-in-ManiSkill3 sim substrate; action-space evidence base; SO-101 failure benchmark; continual-learning contradiction triangle) + 8 spares.

Next: queue_cli.py next → lit-radar-0819 (CPU, GPU-busy window; adamc rides to ~08-12). tiny10k endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity readout. adamc endpoint ~08-12 ~17:00Z → chained k4l2 panel. MolmoAct2 follow-up arms + ArmnetBench checkpoint watch remain owner-decision / watch items.*

Session 2026-08-09 21:47–22:1xZ (work, bounded; 0 new GPU-h — adamc rides 33.2/310, tiny10k 1.8/15; explore): lit-radar-0818 closed — 4 deep reads + fresh sweep as 5 concurrent subagents, 4 Papers pages (athena, probeact, qwen-robotmanip, plasticity-at-scale); all four hooks corrected (ATHENA rollout-anchored + code-free; ProbeAct wrong on both clauses, zero detection metrics; Qwen 38kh = ~65% re-render, nothing released; plasticity WD clause = our own 2602.11137 re-cited). Ideas #6 (trunk-tap gate arm) / #9 (DA+jerk offline filter arm; offline-ATHENA parked) / #17 (fourth attachment pole; proxy-instrument ban) fed. Refill sweep on the 4 mandated new angles: 2/16 dups only (vs 12/16) — lit-radar-0819 queued with 4 priority hooks + 8 spares. check 599; Space pushed.

Updated 2026-08-09 22:51–23:4xZ (real date -u at write: 23:37) — work session (bounded): er_60k first poll = green run, wrong arithmetic — the launch post’s “~0.92 s/step 40k class” was attach_F’s frozen-trunk rate; measured 2.23 s/step ⇒ ~150 GPU-h / endpoint ~08-11, correction + gate re-pin 65→155 posted in-channel. Work item: AdamC post-mortem shipped (chart-led, three matched views).

Journal shows actual relaunch ~22:47–48Z (prior tick’s 22:53Z stamp ran fast, record-only). Next owed at step 5000 (~02:0xZ 08-10): async-save capture line + probe ladder vs 40k curve (ER-init delta primary read). fontaine-tiny10k LIVE local — step 2,700, 21.5 f/min, probe 16.78@500 → … → 11.74@2000 → 11.64@2500 descending, 3.0/15 GPU-h; endpoint ~05:1xZ 08-10 → chained panel_v2 → Δ_capacity read.

My cost-correction post (23:01Z) invited an objection to the ~150 GPU-h spend — none as of 23:4xZ; run rides.
