Updated 2026-08-07 09:49–10:3xZ (real date -u) — work session (bounded, then owner-steered live): #19 dT-TABLE READ SCRIPT LANDED (tsens_dt_results.py), then LEDGER → LEADERBOARD (owner steering 10:04Z): evergreen scoreboard with the mean-of-10 flow teacher/student rows and a measured compute column.

Status (babysit 09:50Z + 10:00Z, both green, exit 0):

box molmo2 AR 40k — 15240/40k, loss 3.289, 2.192 s/step, vram 67.07 ≤ 71, probe low 6.69@14500 (latest 6.73@15000, gate margin 5.36). The ~15-min log pause at 15000 was the checkpoint save, verified on-box (37 GB: 29.1 GB full-trunk AdamW optimizer + 9.7 GB bf16 trunk; writes fast, rank-0 serialization dominates). Save-pause-aware ETA: ~17.5–18 h to endpoint (10 saves × ~15 min on top of the 2.19 s/step arithmetic), still ~08-08.
local draws10_t1 — 20832/25800, window 46.2 f/min, cumulative 33.4 f/min → ~12.9 h total, INSIDE the 24 GPU-h gate, ~2.5 h remaining; boundary ~12:3x–12:5xZ → frozen reads.

Steering (live exchange 10:04–10:1xZ): (1) Ledger is out of date — rename it Leaderboard, evergreen, best models in one place, including the missing flow teacher/student mean-of-10; add a compute column (ms/sample?). → Executed this session (below); compute column = structural evals/frame (exact) + measured batched-eval ms/frame from banked logs (⏱ timed / ≈ mtime-bounded), with a queued same-config micro-benchmark to replace the ≈ rows and add batch=1 latency. (2) Why is molmo2 checkpoint saving so slow? → Answered on Discord with on-box facts (37 GB/save, ~14% wall overhead) + two opt-in fixes (weights-only intermediate saves / async save); holding for a go, not changing the live run.

Done: LEADERBOARD live (leaderboard, ledger.html redirects): scoreboard sorted by panel MAE on the identical 25,800 frames — student 1-NFE mean-of-10 5.3675 (~69 ms/frame ≈) and teacher heun30 mean-of-10 5.3645 (best first_mae 1.4242; ~600 ms/frame ≈) tie on chunk at 30× different expert compute; AR greedy 5.8026 (88.7 ms/frame ⏱); ☆ ≤ 5.0 open (gap 0.37), ☆☆ first-mae arm crossed. Pending rows named: AR mean-of-10 (today’s boundary), molmo2 endpoint (~08-08); tsens rungs excluded by pre-reg (record-only). Verification para updated: the AR-100k local re-score IS done (5.8026/2.1431 reproduced; read scripts re-derive from npz). Earlier: #19 dT-table read script (tsens_dt_results.py, commit 38fde8e) — the T-parameterized sibling loader the queue item’s audit named: registered T set {0.5, 0.7, 1.0, 1.3} ONLY, one record-only table (pooled chunk/first per T on the same frozen q4 rows; the T=1.0 row re-pooled from the full-panel primary npz via the join_rows subset join), NO decision branches per the pre-reg sensitivity clause — never a headline, never a license to re-pick T. Oracle PASS pre-data: a synthetic T=1.0 rung fixture reproduces the primary’s q4 re-pool EXACTLY (float-equal, delta 0.0); ×0.93/×0.98/×1.07 rung fixtures land at exactly factor × the re-pool; 11 guard aborts fire (unregistered T, wrong plan/draws/ar_temperature, policy+stem tag mismatch, rung-row disagreement, full-panel-as-rung, state-copy drift, checkpoint mismatch, report drift). Defaults = the tsens launcher’s exact stems, so the read is one command when the rungs land. Queue: dT item DONE; refills = the pre-endpoint attachment-frontier lit slice + the leaderboard micro-benchmark prep (validate green, depth 3, 13 open). check.py 437 passed.

Next (queue_cli.py next): endpoint-runbook git-audit (CPU, this GPU-busy window → run_work_next armed), then micro-benchmark prep + the attachment-frontier lit slice; draws10_t1 boundary ~12:3x–12:5xZ today → frozen reads land as leaderboard row; endpoint ~08-08 (save-pause-aware) → #19 box obligations → K smoke ladder → attachment steer window.

Updated 2026-08-07 09:46–09:5xZ (real date -u) — tick (babysit): both runs green, no new steering; papers backlog cleared last session, #19 CPU items open → work session chained.

Updated 2026-08-07 09:29–10:0xZ (real date -u) — work session (bounded): PAPERS SECTION BATCH 3 — RETROACTIVE BACKLOG CLEARED — four final theme pages / 13 papers, all 42 tracker sources now covered; the deep re-reads corrected seven banked claims, two of them citations to content that isn’t in the cited papers at all.

Steering: none new (polls at 09:29Z and 09:41Z clean; owner last at 08:42Z — the papers steering, this session finishes the retroactive half of it).

Done: papers batch 3 — grounding & conditioning placement (IVRA, FLOWER, SCALE, SmolVLA), action tokenization (FAST, FASTer), data & trunks (Rethinking VLA scaling, data-engine survey, VLM-to-VLA redundancy, LoRA-r32), the attachment frontier (AR-VLA, Anchor-Align, π0.7/WAM post); index tracker 42 covered / 0 remaining — backlog cleared. Seven correction hooks banked to ideas.md, the loud two: the data-engine survey contains zero dedup/contamination content (we had projected our #18.7 census onto it — the honest cite is that the field’s survey omits the axis our census covers), and 2606.31382 makes no backbone-scale claim (the bigger-isn’t-better prior belongs to VLM4VLA, which it merely cites). Also corrected: FLOWER’s 50%-prune is encoder-decoder-only (decoder-only optimum 30%, tap at ~70% depth → arm B’s null-branch follow-on is one deep tap, not early streams); SCALE has no token budget (it’s uncertainty-gated temperatures, AR-path pluggable); SmolVLA’s L/2 cut is a compute tradeoff their own table shows losing 1.8 to full stack; 2602.09722’s negative transfer is frozen-VLM-only with no selective-mixture method; IVRA’s LIBERO claim mis-attributed LLaRA. New banked positives: AR-VLA’s +25-pt history-length ablation + its independent AR-side confirmation of the K premise; Anchor-Align as a third seam recipe (beats Co-training+KI 71.9 vs 43.8 on semantic OOD; VQA-retention probe worth stealing); Fast-WAM as evidence the video prior, not generation, carries WAM value; π0.7’s text-subgoals-insufficient flag pre-banked into the #6 rung-(a) read. check.py 437 passed. Blog built + Space pushed (4 new pages + index + now curl-verified 200); Discord posted 09:5xZ (id 1535222409555091516).

Updated 2026-08-07 09:10–09:5xZ (real date -u) — work session (bounded): PAPERS SECTION BATCH 2 — three more theme pages / 13 papers (one-step menu, sampling-beyond-selection, state-shortcut set), 29 of the tracker now covered; the deep re-reads corrected three banked claims, including one that re-frames a completed experiment.

Steering: none new (polls at 09:11Z and 09:20Z clean; owner last at 08:42Z — the papers steering, this session executes batch 2 of it).

Done: papers batch 2 — one-step menu (OFP, MeanFlow-VLA, Let It Be Simple, GoldenStart), sampling beyond selection (Golden Ticket, DVAC, Energy Policy), the state shortcut (Adapt Your Body, state-free, ReViP, GAP, ThinkProprio, Cloak); index tracker 29 covered / 13 remaining. Full-text re-reads corrected three banked claims (hooks in ideas.md, record on the pages): #9’s p=0.8 zero-masking was the baseline of a since-WITHDRAWN paper, not its method — arm C tested the family’s weakest member, and the cross-paper consensus is modulate-don’t-amputate; #1’s Golden Ticket bank was v1-stale (v3: 46/51; per-task tickets always gain, only shared tickets regress); #12’s MeanFlow hook missed that its 8.7× speedup loses accuracy (78% vs 84.5%), and Let It Be Simple’s one-step win is state-carried and degrades 10-step decoding. check.py 437 passed. Blog built + Space pushed (3 new pages + index + now curl-verified 200); Discord posted 09:5xZ (id 1535217206403792936).

Done: Papers section batch 1 LANDED (44eb032) — papers/ mdbook section; index doubles as the retroactive backlog tracker (16 of ~38 papers covered, remaining grouped by theme). Eight pages, each contribution / experiments / what-transfers / which-arm-it-fed, written for a reader with less context: π0.5 + KI, LabVLA, Q-VGM, the 7-paper test-time-selection cluster, SnapFlow (incl. our own replication), the seam debate: AEGIS + Wall-OSS-0.5, encoder-grafting, Hi-VLA + CAC-VLA. Re-reads at full-text depth caught real corrections, banked as ideas.md hooks: Wall-OSS-0.5’s seam ablation has stop-grad WORST (co-train 57.0% > flow-only 36.6% > stop-grad 31.9%, from-scratch regime — context for #4’s decision branches, not an indictment of KI-in-posttraining); the frozen-VLA probe’s 26.7→44.3 selector result is simulator-rollout-assisted, not probe-only (#19); Q-VGM’s 79.0→92.5 is arXiv v2 of a major rewrite; LabVLA runs NO recipe ablations (adoption evidence, as banked) and uses α=10. check.py 437 passed.

Audit honored: mean/best/dispersion stay in selection_ceiling_results.py; ES only, draws_fairness math reused verbatim. Oracle PASS pre-data: degenerate draws=1 → interaction exactly 0 + ES == direct RMS-L2; the banked read-4 numbers reproduced EXACTLY through this file’s own join + pooling; N=2 hand fixture; 5 abort guards. check.py 437. Queue refill: endpoint-runbook-git-audit (pre-endpoint stems/pgrep/flags audit of every blocked endpoint-chain item, BEFORE the ~08-08 window opens). Lit slice (~15 min): LabVLA (2606.13578) — independent adoption of our exact stage-1-AR → stage-2-KI-attach recipe → #4; Q-VGM (2606.08015) — offline RL on frozen-trunk + flow-expert → #4 (the F-arm keeps an RL escalation path).

Done: 485194b — idea17-vu5k-finalization-prep executed whole: amendment-3 flag set byte-audited clean against bijou.train at HEAD (--init-from = weights-only fresh-AdamW loading expert+prompt+adapted-backbone; cosine-to-10%-floor shared by ALL LR groups → vision=text through the schedule; no-tower hard-abort → no silent no-op unfreeze); both arm launchers landed (launch_box_fontaine_molmo2_vu5k_{frozen,thawed}_ddp4.sh — base 40k recipe byte-identical, arm-vs-arm diff exactly --backbone-vision-lr 6e-6, plan sha pinned; thawed refuses without the frozen endpoint AND the vu5k_mem_ready smoke record) + prepared babysit.toml entries (vram-71 gates, FILL-AT-FINALIZATION probe bars). check.py 467 green. queue.json: prep → done, execution → launch-only-after-smoke (4 cells: smoke, endpoint-probe quote, amendment POST, owner go), +molmo2-endpoint-postprocessing refill (depth 2 green). fae8c5d — lit slice: HiRoC (2608.05999) + VLA-Talker (2608.05738), both announced today, page papers/subgoal-sourcing-post-training.md — two directional priors for the selfsubgoal probe (Δ_self ≤ Δ_oracle cold-start prior; inject-vs-supervise 15.9-pt gap → narrated arm safe) + the honest tension with our aux-on +0.462 resolved as a flagged synthesis; #16 evidence-injection few-shot hook banked; stale #17 index bullet fixed. Blog built + Space pushed (page 200-verified).

Next: queue_cli.py next → idea19-tsens-dt-read-execution (opens at t1.3 completion, revised ~23:1x–23:3xZ tonight); molmo2-endpoint-postprocessing opens at the endpoint chain (~04–05Z 08-08). Then endpoint → #19 box obligations → K smoke ladder → attach-screen window; #1 execution behind tsens + selfsubgoal per pre-reg. run_work_next re-armed — the tick after t1.3 lands chains into the dT read. Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 19:38–19:4xZ (real date -u) — tick (babysit): quiet — both runs green, no steering, no new reactions. Timestamp correction: the previous session’s labels ran ~40 min fast — its “19:03–20:2xZ” entry actually ran 19:03–19:38Z (its commit 9c50f9f landed 19:38:26Z), its “20:1x” babysit polls were ~19:3xZ, and queue.json’s updated_utc was future-dated 19:47Z (fixed to real time this tick). Log-derived facts (endpoints, rates, gates) are unaffected — they come from run timestamps, not labels.

Status (babysit 19:39Z, exit 0):

box molmo2 AR 40k — 28380/40k, loss 2.926 (−0.028 over the window), 2.203 s/step (24.8 steps/min), vram 67.07 ≤ 71. Probe 6.88@28000 (low 5.91@26500 stands, gate margin 4.93). Endpoint ~04–05Z 08-08 unchanged (~7.1 h compute + save windows).
local ar100k_tsens_q4 rung t0.7 — 2112/4301; the 0 f/min babysit window is the 160-frame flush quantization (log mtime 19:34:40, ~5 min old ≈ one chunk at ~29 f/min; 4 procs + 12.7 GB GPU live). Cumulative projection 7.5 ≤ 12 GPU-h. t0.7 ends ~21:2xZ, t1.3 ~23:5xZ → dT read opens ~00:3xZ 08-08.

Steering: none (read empty 19:39, history -n 5 shows no new owner messages or reactions; the 18:5xZ golden-ticket exchange stayed quiet after the 19:33Z instrument post).

Done: quiet tick — babysit exit 0, both runs judged healthy (t0.7 zero-window = known quantization, verified against the log mtime); timestamp-drift correction recorded (see header) + queue.json updated_utc fixed; queue_cli.py validate green (depth 2, 14 open); run_work_next already armed by the prior session (19:38:27Z) — left standing: GPUs busy + CPU item queued.

Next: chained work session → idea17-vu5k-finalization-prep (CPU, wanted before the molmo2 endpoint ~04–05Z 08-08). idea19-tsens-dt-read-execution opens at rungs completion ~00:3xZ 08-08. Then endpoint → #19 box obligations → K smoke ladder → attach-screen window; #1 execution behind tsens + selfsubgoal per pre-reg. Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 19:03–19:38Z (times corrected from the mislabeled “19:03–20:2xZ”; real date -u) — work session (bounded): #1 golden-ticket INSTRUMENT LANDED (0acabde, all 4 pre-reg oracles green, screen now launch-only) + a molmo2 stall false-alarm run to ground (save-window anatomy, babysit anchor) + lit slice (LAFM Papers page, same-session per the standing rule).

Status (babysit 19:04Z + 19:33Z + ~19:36Z — last label corrected from “20:1xZ”, see the drift note above):

Save-window anatomy banked: every save-every-2500 boundary blocks ~15.5 min writing ~38 GB synchronously (~42 MB/s; s_per_step ~48.6 on every post-save line 2500→27500 — py-spy workup of the 27500 window: ranks block on the first CUDA call of the next step, one GPU idles, jsonl mid-write). The 19:03 half-rate poll was THAT, not an incident; anchored in babysit.toml. Endpoint arithmetic sharpens: ~7.1 h compute + ~1.3 h saves → ~04–05Z 08-08.

Steering: none (polled at boot 19:04, 19:33, ~19:36 — the only new message was our own instrument post; the 18:5xZ golden-ticket exchange is quiet).

Done: 0acabde — #1 golden-ticket instrument, the queue’s flagged CPU item, landed whole: --noise-tickets mode in bijou.eval via a new _flow_noise seam (noise = tickets[draw] frame-independent, draws-major; policy name gains _ticket; report JSON + draws npz carry noise_tickets/tickets_sha256; keyed path proven byte-identical pre/post refactor), bank plans/tickets_goldenticket_m64.npz committed (64×[50,6] f32, SeedSequence [0x54434B54,0,m], file sha 9bb13bc4…, content sha a07c062a…, generate-once + --verify), 7 pytest oracles (tests/test_golden_ticket.py: draws-1 contract bit-exact vs sample_actions(noise=), cross-frame ticket property asserted in-process, two-run determinism, dual sha pins, loud refusals) + ticket_scores.py stage-1 scorer with frozen R1 kill line, R4a per-dataset matrix, and --oracle green (pooling reuse reproduces the banked 6.5997 and all 10 per-draw probe MAEs EXACTLY). check.py 467 green (was 460). No semantic deviation → no amendment. Discord post up. This commit (blog): LAFM Papers page (papers/latent-action-priors.md, 2606.23420 — learned mode-prior libraries; the noise-structure ladder above the ticket screen now mapped in ideas #1, DSRL named as next read if stage 1 CONFIRMs) + VLM4VLA staged-cell addendum to vla-initialization.md (+18.1 pre-freeze adaptation cell — sharpens the honest prior on #17’s thawed-vs-frozen read). queue.json: instrument → done, execution → launch-only, +idea17-vu5k-finalization-prep (CPU carve-out of the held execution item; depth 2 green).

Next: queue_cli.py next → idea19-tsens-dt-read-execution (opens at rungs completion ~00:3xZ 08-08); GPU-busy windows → idea17-vu5k-finalization-prep (CPU, wanted before the molmo2 endpoint ~04–05Z 08-08). Then: endpoint → #19 box obligations → K smoke ladder → attach-screen window; #1 execution behind tsens + selfsubgoal per pre-reg. Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 18:37–19:0xZ (real date -u) — tick (babysit) turned conversational: owner live in-channel — #17 amendment 2 landed (5k/arm, fresh-Adam route owner-confirmed 18:39Z) + golden-ticket in-depth explainer posted (owner’s 18:33Z question); recovered the killed 18:24 session’s uncommitted param-group correction.

Status (babysit 18:38Z):

box molmo2 AR 40k — 27140/40k, loss 2.9399 (falling −0.016 over the window), 2.167 s/step, vram 67.07 ≤ 71. Probe 6.81@27000 (5.91@26500 stands as the low). Gate margin 4.93. ~7.7 h to 40k.
local ar100k_tsens_q4 rung t0.7 — healthy: 352/4301 at the 18:38:39 flush (160-frame chunks 32→192→352, ~20 f/min incl. model load; util 24–25% steady). Babysit exit-3 “gate crossing” (projection 59.6 h) judged FALSE POSITIVE — the cumulative baseline still anchors at the 15:58Z t0.5 launch while the per-rung frame counter reset at the 18:21Z roll; artifact anchor added to babysit.toml. Real cumulative ≈ 2.7 GPU-h ≤ 12. t0.7 ends ~21Z, t1.3 ~23:3xZ → dT read ~00Z.

Steering (owner live 18:31–18:39Z, conversational mode): (1) 18:31Z seed/rewarmup/5k/LR message → answered 18:35Z by the prior session; (2) 18:33Z “tell me more in depth about optimising the initial noise vector” → in-depth explainer posted 18:40Z (ODE-map claim, why the panel makes the search ~free, banked-null machinery, shared-ticket prior against, per-dataset escalation path); (3) 18:39Z “you’re right re: fresh adam optimisers” → the offered resume-with-injected-vision-group patch is DROPPED, fresh-AdamW --init-from confirmed → amendment 2; (4) 18:43Z batch/reheat/ warmup-500 questions + 18:49Z “2e-6 seems kind of small” → recommendations posted (batch 48 unchanged, 0.3× reheat, warmup 500, vision = text = 6e-6), owner “Ok, agreed” 18:51Z → amendment 3 landed same session (Space-verified live); (5) 18:51Z golden-ticket follow-up (per-dataset tickets? rig inference-time use? search mechanics?) → replied 18:5xZ: per-dataset matrix is free from stage 1’s dump (R4), record-only pending per-dataset confirms (selection noise + multiplicity), rig ticket = constant [50,6] tensor searched offline on rig data (offline-vs- rollout caveat stated), search = batched draws-64 random search. Exchange may continue — chained session rejoins via history.

Done: tick — #17 amendments 2 AND 3 (A2: 5k steps/arm, vu5k naming incl. eval stems, gate 24→32 GPU-h with recomputed arm costs 12.2/13.9; A3: batch 48 unchanged, LR reheat 0.3× the 40k peaks — decoder 3e-5 / text 6e-6 fresh 5k cosine to 10% floors, --warmup-steps 500, vision LR 6e-6 tied to the text group — every constant owner-agreed in-channel 18:51Z); recovered + re-verified the 18:24 session’s uncommitted 5-vs-3 group-count correction (bijou/train.py:3385-3410: decoder 1 group, +2 decay/no-decay per unfrozen backbone group) and stated the correction in-channel; blog built + Space pushed (post curl-verified 200, amendment content live); check.py 460 green; queue validate green (depth 2, 14 open); run_work_next armed. Three Discord posts (explainer, lock-in, amendment confirmation).

Next: #17 design is now settled through amendment 3 → finalization amendment only (byte-audit + memory-ladder smoke + endpoint-probe quote + vu5k launchers) + owner go, window post-attach-screen. GPU-busy windows → idea1-golden-ticket-instrument (CPU). tsens dT read opens ~00Z; molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window. Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 18:00–18:2xZ (real date -u) — tick (babysit): owner steering 18:02Z on #17 (warm-start the unfreeze from the 40k checkpoint, two arms frozen/thawed — replied in-channel, agreed, amendment falls to the chained session) + tsens rung roll t0.5 → t0.7 caught live 18:21Z, babysit stem repointed.

Status (babysit 18:00Z + 18:21Z):

local ar100k_tsens_q4 — rung t0.5 COMPLETE 4301/4301 ~18:21Z (json + html + npz written); t0.7 launched 18:21Z (--ar-temperature 0.7 confirmed on the live process), babysit log stem repointed t0.5 → t0.7 in babysit.toml. The 18:00 zero-window was the flush-quantization artifact again (log flushes in 160-frame chunks; mtime 17:56 at 3552). Cumulative gate projection 2.5 ≤ 12. t0.7 ends ~21Z, t1.3 ~23:3xZ → dT read ~00Z.

Steering (owner 18:02Z, replied 18:2xZ): on #17 — start from the 40k checkpoint, two arms frozen/thawed instead of the from-scratch 10k screen; “startup mindset, shortest time to high quality rollouts”. Agreed in the reply: frozen-continue is the control (extra steps alone move the number), read = thawed vs frozen paired per-frame Δ; ~15 GPU-h (2 × ~3k steps) vs ~27, and it upgrades the deployment artifact directly. Caveat stated: late low-LR thaw can understate unfreeze-from-scratch (lit co-adapts vision from step 0) — asymmetric bet, acceptable. #17 draft amendment = next chained-session item (arms, steps, tower Adam warmup, kill lines; execution window unchanged post-attach-screen, still owner-held).

Done: tick — babysit 18:00Z exit 0 both green; held the session through the rung boundary (charter §6), verified the roll on the live process list, repointed the stem; owner reply posted in-channel; queue_cli.py validate green (depth 2, 14 open); run_work_next armed (was already, 17:59). No blog build (Discord reply + now.md only).

Next: chained work session → #17 draft amendment to the warm-start two-arm design (owner steering, jumps the queue) + rejoin the thread via history; then idea1-golden-ticket-instrument (CPU) in GPU-busy windows. idea19-tsens-dt-read-execution opens at rungs completion ~00Z. molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window. Every GPU launch goes through run_detached.sh.

Instrument = a ticket noise-key mode at the noise_for_item seam, 4 oracles frozen in the post. check.py 460 green; posts/index.md drift fixed (4 missing entries added).

box molmo2 AR 40k — 25280/40k, loss 3.047, 2.191 s/step, vram 67.07 ≤ 71. Probe 7.10@25000 (in-band vs the 5.97–7.18 recent band, no ≥7.5 pair). Gate margin 4.93. ~9.0 h to 40k → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — 2592/4301 @ 49.7 f/min window, cumulative 29.0 f/min, projection 2.5 ≤ 12 gate. Rung roll t0.5 → t0.7 ~18:3xZ (repoint the babysit log stem at the first tick after); all rungs ~20-21Z → dT read opens.

Steering: owner 17:04Z — “what evidence on unfreezing our SigLIP encoder in molmo2, helpful or harmful?” Answered 17:2xZ from the banked pages (VLM4VLA/APT/KI prior), then a targeted lit slice found the missing pole and a correction was posted 17:5xZ: MAPS (2511.19878) and the dual-encoder paper (2509.11417) are real harm cases — in the OOD-retention regime, not ours. Net: both poles real; our rung is adaptation-regime → unfreeze should help the panel; recipe prior full-FT tower at low LR, never LoRA-on-SigLIP. Disposition: idea17-molmo2-vision-unfreeze-prereg-draft queued (draft CPU; execution post-attach-screen, owner-steered).

Done: this session — (1) idea16-critical-frame-repooling (4773ba9 pre-reg + instrument BEFORE the read; 3da7695 results): the CI-MSE concern tested on our own board at zero GPU cost. Frozen rule (chunk window hits subgoal boundary | holding bracket | event), coverage 99.9%, 11,204 critical core frames. All 10 pairwise gaps keep their published sign with CI95 excluding 0; separation vs state-copy widens on critical frames (+6.18 → +6.74) — opposite of CI-MSE’s easy-frame-dilution mode. Robustness note on the leaderboard; critical_frame_repooling.py (–selftest oracle) reusable at the molmo2 endpoint. check.py 460 green ×3 commits. (2) Lit slice + papers page (vision-encoder-freeze, 4 sources, 3ac7775) — see Steering; correction to the first reply posted same session. (3) Queue: idea16 done; idea17-molmo2-vision-unfreeze-prereg-draft refilled; validate green depth 3.

Next: queue_cli.py next → idea19-tsens-dt-read-execution opens at rungs completion (~20-21Z tonight; script landed, record-only vs the decode-temperature page’s written prior); then golden-ticket + vision-unfreeze pre-reg drafts in GPU-busy windows. Dated boundaries: tsens rung roll ~18:3xZ (babysit stem repoint t0.5 → t0.7 at first tick after) → all rungs ~20-21Z → dT read; molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production at 1250 cadence). Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 16:53–17:0xZ (real date -u) — tick (babysit): both runs green, no steering. One anomaly chased and cleared: the tsens babysit window read 0.0 f/min — adjudicated log quantization (the progress log flushes every 160 frames, ~one line per 6 min at current rate, and the poll window was 3 min); verified healthy by watching the next line land on schedule.

Status (babysit 16:53Z):

box molmo2 AR 40k — 24780/40k, loss 3.020, 2.195 s/step, vram 67.07 ≤ 71, 27.7 steps/min window. Probe 6.81@24500 (in-band, no ≥7.5 pair). Gate margin 4.93. ~9.3 h to 40k → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — babysit window 0.0 f/min (1472→1472 over 3 min) — adjudicated HEALTHY, not a stall: the log flushes in 160-frame chunks; the next line (scored 1632/4301) landed 16:54:35Z, 5.6 min after its predecessor → 28.5 f/min, on the cumulative rate. Cumulative 26.6 f/min, projection 2.7 ≤ 12 gate, ~1.6 h remaining. Babysit note for future ticks: a window <6 min can legitimately read 0.0 f/min on this run — judge on cumulative + log mtime. Rung roll t0.5 → t0.7 ~18:3xZ (repoint the babysit log stem at the first tick after); all rungs ~00Z 08-08.

Steering: none (read: only our own 16:52 close post; history -n 5: no reactions).

Done: tick — babysit exit 0, molmo2 clean; tsens 0.0-window anomaly chased to the 160-frame flush quantization (verdict healthy, confirmed live); queue_cli.py validate green (depth 3, 13 open); run_work_next already armed 16:53Z — chained work session follows (GPUs busy, CPU items queued: critical-frame re-pooling pre-reg, golden-ticket pre-reg draft). 16:34 tick + 16:06 work entries + 15:22 footer note rolled to archive. No Discord post (16:52 close current), no blog build (no reader-visible change).

Next: chained work session → next CPU queue item; tsens rung roll ~18:3xZ (babysit stem repoint t0.5 → t0.7) → all rungs ~00Z 08-08 → dT read against the papers page’s written prior (record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production, now at 1250 cadence). Every GPU launch goes through run_detached.sh.

Previous update 2026-08-07 15:56–16:2xZ (real date -u) — tick (babysit + incident + owner q): tsens q4 DEAD AGAIN at poll — THIRD driver-background-task-guard incident, ROOT CAUSE UPGRADED: the 15:13:44Z setsid relaunch was killed ~15:54–15:56Z when fontaine-tick.service finished (journalctl: unit stopped 15:56:18Z → systemd killed its whole cgroup; setsid escapes the terminal session, NOT the cgroup). Relaunched 15:58:26Z via systemd-run --user --unit=fontaine-tsens-q4 — its own transient unit, actually outside the driver’s cgroup. Owner question 15:48Z (“what is tsens t0.5?”) answered in-channel 15:57Z. molmo2 green.

Status (babysit 15:56Z):

box molmo2 AR 40k — 23240/40k, loss 3.0747, 2.229 s/step, vram 67.07 ≤ 71, 26.3 steps/min window. Probe 5.97@22500 → 6.05@23000. Gate margin 4.93. ~10.4 h stepping + saves → endpoint ~08-08 morning.
local ar100k_tsens_q4 3rd launch — rung t0.5 restarted from frame 0 (992 frames = ~40 min lost from the 2nd kill). Launch sequence: draws10_t1 registry entry temp-restored from 85cdc0a → primary gate re-passed 12.7 ≤ 24 → entry re-pruned; first systemd-run attempt died exit 127 (uv not on the clean unit’s PATH — fixed with --setenv=PATH/HOME); gate + rung T=0.5 start confirmed in journalctl --user -u fontaine-tsens-q4. babysit started_utc repointed 15:58:26Z. Rung roll t0.5 → t0.7 now ~19:1xZ (repoint the babysit log stem); all rungs ~01:3xZ 08-08.

Steering: owner 15:48Z asked what tsens t0.5 is — answered 15:57Z (T-sensitivity rung definition + record-only framing) in the same post as the third-incident report; no further reply by close.

Done: tick — babysit (molmo2 green; tsens dead-run diagnosed to the CGROUP mechanism via journalctl, not a compliance failure of the setsid rule); tsens relaunched in a transient unit + gate re-passed + registry dance executed + started_utc repointed; queue item driver-background-task-guard gained third-incident evidence + the systemd-run codification ask; memory file no-end-turn-waiting-on-notifications REWRITTEN (setsid insufficient by mechanism; systemd-run pattern + PATH gotcha); owner q answered; queue_cli.py validate green (depth 2, 12 open); run_work_next already armed.

Next: chained work session → driver-background-task-guard (now with the true mechanism in hand: codify systemd-run as the required GPU-launch wrapper, consider KillMode=process for the tick service, driver test). Boundaries: tsens rung roll ~19:1xZ (babysit stem repoint) → rungs complete ~01:3xZ 08-08 (dT read, record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production).

Previous update 2026-08-07 15:11–15:3xZ (real date -u) — tick (babysit + incident): tsens q4 was DEAD at first poll — killed ~15:07–15:11Z by the driver’s turn-completion teardown, the SECOND driver-background-task-guard incident in one day (the work session launched it 15:01:40Z as a session task, not setsid-detached); relaunched setsid-detached 15:13:44Z, primary gate re-passed, rung t0.5 restarted from frame 0 (32 frames lost, ~6 min compute). molmo2 green.

Status (babysit 15:11Z):

box molmo2 AR 40k — 22460/40k, loss 3.0866, 2.198 s/step, vram 67.07 ≤ 71, 27.4 steps/min window. Probe 6.22@20500 → 6.55@21000 → 7.18@21500 → 6.93@22000 (bouncy inside the band, no ≥7.5 pair, watch not tripped). Gate margin 4.93. ~10.7 h stepping + saves → endpoint ~08-08 morning.
local ar100k_tsens_q4 incident + relaunch: first poll found GPU 0 empty, 1 pgrep match (my own shell), log frozen at “scored 32/4301” (mtime 15:07), NO traceback, NO OOM (dmesg + journalctl clean) — external SIGKILL signature, timed at the 13:04Z work session’s end (~15:11Z close post). Same mechanism as 12:56Z: the driver kills session background tasks at turn completion; the launch was NOT setsid-detached despite the memory-file mitigation. Relaunched 15:13:44Z setsid nohup — required temporarily restoring the pruned draws10_t1 registry entry (the launcher’s PRIMARY GATE reads its started_utc; restored from 85cdc0a, gate re-passed 12.7 ≤ 24, entry re-pruned). Rung t0.5 scoring verified live (first progress line + GPU fed) before commit; babysit started_utc repointed to 15:13:44Z (the 22.7 h “gate crossing” at first poll was the dead run’s elapsed-vs-32-frames artifact, not a real cost breach — voided by the relaunch). Second-incident evidence appended to the driver-background-task-guard queue item.

Steering: none new (read = our own 15:11Z close post; history -n 5 shows nothing unrecorded — 13:35Z 👍 “Great stuff” and 13:58Z async-ckpt HIGH already in the 13:04Z entry).

Done: tick — babysit (molmo2 green; tsens dead-run adjudicated to a measured verdict: driver teardown, not crash/OOM); tsens relaunched detached + verified scoring; draws10_t1 entry restore→gate→re-prune dance executed; queue item updated with second-incident evidence; queue_cli.py validate green (depth 3, 12 open); run_work_next already armed (async-checkpoint-saves HIGH next). No blog build (no reader-visible content change).

Next: chained work session → async-checkpoint-saves (owner HIGH, target before the attach-screen launch) — and driver-background-task-guard just earned its second incident; consider pulling it forward, it is now killing GPU runs at a rate of two per day. Boundaries: tsens rungs roll (repoint babysit log stem t0.5 → t0.7 → t1.3); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attachment steer window.

Previous update 2026-08-07 13:04–15:2xZ (real date -u) — work session: merge chain executed end-to-end (pre-merge baseline banked → origin/main MERGED 85cdc0a → post-merge speedup measured 9.1× → leaderboard measured-⏱ rewrite + review post live) + owner steering ×4 executed same-session (Ideas refactor + tags, archive sort, async-ckpt queued HIGH, SigLIP answered); tsens q4 rungs LAUNCHED 15:01Z; molmo2 green.

local ar100k_tsens_q4 LIVE (launched 15:01:40Z, primary gate PASS mechanized: 12.7 ≤ 24 GPU-h): rung T=0.5 scoring (verified live 15:1xZ, first progress line + GPU fed), then T=0.7, T=1.3 sequential; ≤12 GPU-h gate; RECORD-ONLY dT diagnostic. Babysit entry ACTIVE; draws10_t1 entry pruned (footgun order honored: launcher consumed started_utc first). Repoint the babysit log stem as rungs roll (t0.5 → t0.7 → t1.3).
Decode microbench COMPLETE + merge landed. Pre-merge sequential baseline: all 7 singles + students-batched + the redo of the killed cell (teacher_heun30_draws10 batched 747.3 ms/frame). The 12:56Z incident cost 4 batched cells their timing (rates lived in the killed parent; logs carry no timestamps) — only that one had a pre/post claim, hence the redo. Merge 85cdc0a: zero conflicts; test_batched_draws.py + 5e-4 tolerance + GIT_* scrub committed WITH it; the lost tile_memory residual guard was CAUGHT by its own surviving oracle at the pre-commit gate and restored. Post-merge measured: mean-of-N at single-draw latency — teacher draws10 single-stream 11,283.6 → 1,245.0 ms/frame (9.1×), student 277.9 → 111.2 (2.5×); batched-throughput teacher 747.3 → 409.6 (1.8×); draws=1 controls reproduce ≤0.3%.

Steering (owner active 13:02–13:58Z, all executed in-session): (1) 13:02Z blog improvements → Ideas refactor DONE (22 per-idea pages + hot/ice index at the old path; details audit repaired 2 git-history corruptions — the lost ## 5 heading, #9’s consumed bullet — and refreshed 4 stale pages) + Now-archive sorted most-recent-first (archive_now.py now rebuilds sorted every roll); (2) 13:05Z codify + tooling → charter §5 permanent rules (ideas structure + same-session index maintenance; sorted archive) + driver-background-task-guard queued; (3) 13:10Z SigLIP q → answered in-channel (frozen, no –backbone-vision-lr; VLM4VLA vision-unfreeze rung noted); (4) 13:26Z naming → two-word tags landed (noise-draws … async-staleness); (5) 13:58Z async checkpoint saves → queued HIGH (async-checkpoint-saves, molmo2 measures ~14% wall in saves; target: lands before the attach-screen launch). Owner 👍 “Great stuff” 13:35Z.

Done: this session — merge chain complete (baseline → redo → merge 85cdc0a → post-merge reruns → leaderboard measured-⏱ columns + AR draws10_t1 row 5 + main-sync review post filled with both speedup tables → blog + Space + report JSONs live); Ideas refactor + tags + archive sort (4f18582, b6b5ff0); charter codification (bd1aea8); tsens q4 launched + babysit entry activated + draws10_t1 entry pruned; queue: 5 items closed, 2 added (driver guard, async ckpt HIGH), tsens live item added.

Next: queue_cli.py next → async-checkpoint-saves (owner HIGH, CPU, target before the attach screen). Boundaries: tsens rungs roll (repoint babysit log stem; reads via tsens_dt_results.py at completion, record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attachment steer window.

Previous update 2026-08-07 12:56–13:1xZ (real date -u) — tick (babysit + incident): the 12:30Z chained work session ended prematurely at 12:56Z (26 min into its 4-h budget) — post-mortemed to a measured verdict, its in-flight artifacts inherited, the decode microbench it took down relaunched detached 12:59Z; molmo2 green; run_work_next RE-ARMED.

Status (babysit 12:57Z; molmo2 green; draws10_t1 liveness fail = the retained-entry signature, expected):

Work-session post-mortem (20260807T123009Z_work.log): ended with terminal_reason: completed — its final turn said “Waiting on bench notifications now — next action fires on the completion event”. The driver treats a completed turn as session end; no notification re-invoke exists, and the harness killed its 3 background tasks at 12:56:07Z, taking down the decode microbench mid-run 5/14 (a child of a session bash task, not process-detached). New footgun — memory file no-end-turn-waiting-on-notifications written: sleep-poll in foreground, setsid-detach GPU jobs.
Decode microbench: 4/14 banked pre-merge (ar_greedy, ar_draws10_t1, teacher_heun30_draws1, teacher_heun30_draws10 — all batched; JSONs in reports/); run 5 (student_1nfe_draws1 batched) killed mid-run. RELAUNCHED 12:59Z setsid nohup (survives session end): remaining 3 batched then all 7 single, sequentially, same pre-reg harness → ~/leaderboard_decode_microbench_20260807_resume.log. Verified live 13:00Z (backbone loaded, sampling-frames phase). Still pre-merge code — the sequential-baseline sequencing the owner 👍’d is intact.
Merge origin/main: deliberately NOT done this tick — the baseline is still accruing in this working tree; merging mid-bench would contaminate the remaining pre-merge runs. It stays item 1 of the re-armed work session, gated on bench completion.
Inherited work-session artifacts, reviewed: (a) md committed — ideas.md #22 async staleness bridging (parked, waits on #16), papers page RTC 2506.07339 + async-methods 2605.08168, main-sync-review post DRAFT (contains PLACEHOLDER_RESULTS_TABLE and anticipatory merge language — do NOT blog-build until filled post-merge); (b) test changes left uncommitted ON PURPOSE: test_batched_draws.py imports tile_memory/tile_stats which land only with the merge — pytest collects it from disk, so check.py fails until then; the chunked-backward tolerance adjudication (1e-5 → 5e-4, cross-hardware calibrated, guarded failure mode ≫1e-2 so still sharp) and the GIT_ scrub fix* (real incident: a linked-worktree pre-commit hook exports absolute GIT_DIR → a test’s throwaway git init re-initialized the real repo; both harness tests now scrub GIT_*) commit together with/after the merge.

Next: chained work session (4-h budget), in order: (1) sleep-poll the bench to completion in foreground (never end-turn-waiting — see footgun), (2) merge origin/main per the 12:26Z steering (tolerance adjudication already staged in tests; commit the test changes with the merge), (3) post-merge draws-config rerun → leaderboard ⏱ rows incl. the batched-vs-sequential delta, fill the draft post’s placeholder → blog build + ledger, (4) tsens q4 launch (prune the draws10_t1 registry entry only AFTER — started_utc footgun). molmo2 endpoint ~08-08 → #19 box obligations → K smoke ladder → attachment steer window.

Previous update 2026-08-07 12:21–12:3xZ (real date -u) — tick (babysit → boundary): draws10_t1 COMPLETED at its boundary — frozen reads run in-tick: ALL PRE-REG EXPECTATIONS MET, falsifier NOT tripped; decode microbench launched 12:26Z on the freed GPU; molmo2 green with the 18000 watch point CLEARED (probe new low). run_work_next touched → work session chains (microbench reads + leaderboard rows + tsens launch).

Contents: (1) 2ee2be5 batched noise-draw ensembling — sample_draws via one solver call at draws×B, 5.6× bf16 (576 ms mean-of-10 on the rig), draws-major so collapse_draws/--dump-draws layouts stay byte-compatible; fp32 seq-vs-batched max Δ 9.2e-5°; (2) 36570c0 --return-home cosine glide via our rollout_safety.home_trajectory; (3) known: test_chunked_backward aux rel-err 1.0004e-4 vs 1e-4 — OUR tolerance call (passes on this box; pin down before touching the bound); (4) bijou/train.py import reorder only. Sequencing (posted): the in-flight microbench finishes pre-merge as the sequential baseline (matches the banked evals the ≈ rows measured) → merge origin/main (normal merge, not ff) → rerun the draws configs post-merge → the batched-vs-sequential speedup lands on the leaderboard as a measured delta. Merge = FIRST item of the chained work session. Owner 👍 on the ack post (seen 12:4xZ) — sequencing plan agreed, no further reply needed.

Done: tick — boundary adjudicated (completion verified on-disk, never off the liveness line alone); frozen reads executed in-tick and posted (Discord 12:2xZ, id …398); microbench launched on the freed GPU; run_work_next TOUCHED → chained work session: microbench reads → leaderboard/ledger rows → blog build → tsens q4 launch → prune the draws10_t1 registry entry. Inherited and committed the 12:1x session’s staged babysit.toml completion note (that session evidently hit its hard kill before committing — the staged note was its only surviving artifact). queue_cli.py validate green (depth 2, 12 open). 11:26Z tick entry rolled to archive. No blog build (reader content lands with the leaderboard rows in the chained session).

Next: chained work session (4-h budget), in order: (1) merge origin/main per the owner’s 12:26Z steering + sync note (after the in-flight microbench completes its pre-merge sequential baseline; adjudicate the test_chunked_backward tolerance call); (2) microbench reads + post-merge draws-config rerun → leaderboard ⏱ rows incl. the batched-draws speedup delta + ledger/blog; (3) tsens q4 launch (eval_ar100k_tsens_q4_draws10.sh, prune draws10_t1 entry AFTER — the started_utc footgun); molmo2 endpoint ~08-08 → #19 box obligations → K smoke ladder → attachment steer window.

Previous update 2026-08-07 09:26–09:3xZ (real date -u) — tick (babysit): both runs green, no new steering; queue green with the papers backlog + #19 CPU items open → work session chained for batch 3.

Done: #4 attachment-screen instrument LANDED (this commit), all three parts oracle-gated per the pre-reg. (1) Molmo2 residual exports — the trunk-side tap protocol existed since WP1 (queue-title audit paid off); the wiring was the gap: Molmo2Encoder residual_exports + Molmo2PromptConfig field, molmo2_residual_taps pins the rule (stride 3, last tap = final layer; 36 ⇒ 2,5,…,35), molmo2_residual_expert_config mirrors trunk geometry, the ar_backbone-only guard lifted for --decoder flow --conditioning-streams residual, checkpoint save/load round-trips (molmo2 flow checkpoints now load via from_checkpoint). (2) --seam-stop-grad — taps detached before adapter projection in BijouModel.encode. (3) --joint-ce — the K arm: Molmo2ARDecoder rider beside the flow expert, CE suffix inside autocast + fp32 flow outside, three-normalizer chunked-backward form, rider tables at decoder-lr, saved as joint_ce.safetensors, and continued from the endpoint’s expert.safetensors under --backbone-init-from — that last pinned in a pre-reg AMENDMENT (“decoder fresh” = the flow expert; fresh CE tables would contradict “continuing verbatim”). 13 new oracles (tests/test_molmo2_residual.py): taps byte-match trunk hidden states, cache bit-identical with/without taps, stream contract + padding invariance, stop-grad zero/nonzero with the naive-joint negative control, and both α-edges bitwise through the real BijouTrainStep (flow half ≡ F-arm step; trunk grads ≡ phase-1 CE step). check.py 423 passed.

Done: #4 attachment-screen pre-reg POSTED (post, this commit) — the queue wanted it before the endpoint so the attachment decision is executable when it opens. Two arms, the seam the ONLY contrast: F (hard-frozen trunk, our default = “extreme KI”) vs K (KI-joint: phase-1 CE objective continuing verbatim at backbone-text-lr 2e-5 + stop-grad seam, α=1 fixed — no tuning, per KI); naive joint NOT re-measured. Matched 10k steps / eff-48 / sequential on the box, F first. Surface held constant: residual conditioning with the molmo2 tap rule pinned (gemma’s rule is KV-share-structural and doesn’t transfer) — 12 taps @ stride 3, layers 2,5,…,35, expert depth 12 h1024; the depth-of-reads dial (#4 arm 1) stays open, explicitly NOT measured. Frozen reads: Δ_seam paired per-frame CI on panel_v2 heun30/draws1/stable; K trunk-drift diagnostic (greedy AR panel vs the 40k endpoint number, band 0.3) as the language-following analog; frozen decision rule — ties → frozen default stands. Gates: vram ≤71, K1-style probe kill (phase-1 curve +3.0 at ≥5k), 70 GPU-h ceiling with matched 5k downshift (draws_rate_gate mechanization pattern). Instrument does NOT exist yet — queued oracle-gated (molmo2 residual exports + guard lift, seam stop-grad, joint CE+flow with α-edge oracles); #20 activation checkpointing is a hard K prerequisite (phase 1 already at 67/71 GiB with no expert).

(2) 6c3cc3b — #19 endpoint launcher prep: eval_box_molmo2_endpoint_draws10_t1.sh makes the molmo2 endpoint read ONE command when the box frees — guards (checkpoint exists, both plans sha256-pinned, 4 GPUs free), greedy arm re-run only if the training launcher’s chained eval didn’t land (box audit first: the live launcher is byte-identical to git, the P7 “uncommitted edit” was a +x mode bit — the chained greedy WILL run at 40k), draws10_t1 arm 4-GPU sharded, and the pre-registered first-~200-frames cost gate mechanized as draws_rate_gate.py (rank-0-shard rate → whole-run GPU-h projection; strict >24 → automated kill + q4 relaunch; timeout-with-partial-progress still decides; no-progress leaves the run to babysit’s registry gate). 10 new oracles (tests/test_draws_rate_gate.py); check.py 410 passed. babysit.toml carries the prepared molmo2_draws10_t1 entry (commented, fill-at-launch).

The queued item said “instrument + pre-reg draft” — a git audit showed both landed 2026-08-06 (78c9f56 + the posted pre-reg; the live draws10_t1 IS the AR-100k arm). What was genuinely missing: the pre-reg quotes its mechanics as oracle-pinned, but only the gemma trunk was — the pre-registered molmo2 arm runs the shared suffix decode over a different cache (Molmo2KVCache), whose by-reference snapshot/restore contract was untested. tests/test_molmo2_ar_sampling.py (5 new CPU oracles): T→0 recovers molmo2 greedy exactly; hot draws grammar-valid/deterministic/distinct; snapshot→decode→restore→decode ≡ fresh-encode decode bit-for-bit over the molmo2 cache; the append-only update() contract pinned directly (an in-place cache fails the test, not draws 2..N silently); ar_predict_sampled dispatch ≡ decoder-level call. check.py 400 passed. Queue re-scoped honestly: arm execution blocked on the endpoint (~08-08), launcher prep queued as the refill; ideas #19 → screening with full status. Lit slice (~15 min, sanctioned): MG-Select (2510.05681) — verifier-free best-of-N via KL(conditional ‖ condition-masked) confidence; its required condition-dropout training is exactly what AR-100k already has (state 0.5, subgoal 0.5) and --mask-state exists → banked to #19 as the zero-training escalation if mean-of-draws lands small; VLA-ATTC (2605.01194) critic-ranked candidates as the trained alternative. Both frame greedy as the bottleneck — opposite our expectation 2; the draws10 primary read adjudicates.

Previous update 2026-08-07 01:19–01:4xZ (real date -u) — work session (chained, bounded): #21 P2 LANDED — the queue is data now (commit 19f3d71). fontaine/queue.json is the CANONICAL queue (now.md narrates it — charter §3 bullet 1 amended per the signed diff); fontaine/scripts/queue_cli.py list/next/depth/validate machine-gates what ticks used to eyeball: depth ≥ 2 or a stated depth_reason, every gpu- item must name a pre-reg post that EXISTS on disk, owner_hold forces blocked (a held item can never be silently pickable), unique ids + schema. 8 oracles in tests/test_queue.py incl. the real queue validating green; the signed prompt diffs applied (tick §5 runs validate; work boot reads queue.json, end gate requires validate green). Migration: 10 items (2 live runs, 5 queued CPU: P4→P5→P6→P7→#6 pre-reg draft, 3 blocked: frozen reads @ draws10 boundary, stage-2 decision @ molmo2 endpoint, arm A img280 HELD). One stated deviation from the signed spec: the CLI is queue_cli.py, not queue.py — sibling scripts sys.path.insert the scripts dir, so a module named queue shadows the stdlib; torch spawn children (test_zero1, test_chunk_grad_allreduce) died on from queue import Queue inside check.py — the gate caught it pre-commit, root cause traced (not vibed as flaky), class fix = never stdlib-shadow in a path-inserted dir. check.py 372 passed.

P3: repo pre-commit hook (fontaine/harness/hooks/pre-commit, installed via core.hooksPath in the driver) — code commits run check.py and its exit status IS the gate (the 9f26f13 piped-exit-code class is closed); *.md / harness/state/ / blog/book/ commits stay instant; FONTAINE_SKIP_CHECKS=1 escape hatch prints loudly. Live-tested all three paths: a lint-failing commit BLOCKED, escape hatch lands, md-only commit 0.01 s. P1: fontaine/scripts/babysit.py — one command per checkpoint, built to the owner’s three constraints: liveness by pgrep + GPU-mem floor (never a log tail; exit 1 on a dead rank), trajectories not verdicts (last-k probe values, loss delta vs previous cached sample, window rate vs cumulative, anchors printed alongside; an oracle asserts no verdict language in gate lines), gate crossings SURFACED (exit 3) never acted on; the Discord poll runs last and unconditionally — a checkpoint cannot skip it. Registry fontaine/harness/babysit.toml (one entry per live run, updated at launch); 13 oracles anchored to the hand-verified 00:59Z window (37.2 f/min, 27.8 cumulative, 15.46 h projection); tick/work prompts now point at the CLI. The second live call earned its keep immediately: probe 12.5951@3000 — the FIRST non-descending anchor (30.84@500 → 25.72 → 15.25 → 13.21 → 12.09@2500 → 12.60@3000). Judgment (charter §6): single-anchor wiggle after a 60% descent, loss delta +0.025 (log noise), K1 gate is @10k — watch @3500, no action.

Owner constraints absorbed into P1: (1) must catch training crashes — it does by construction (liveness = pgrep + GPU-mem, never a log tail); (2) show metric trends/history for qualitative judgment; (3) never a purely mechanical verdict — so P1’s output contract is now trajectories, not verdicts (last-k probe values, loss deltas, rate windows vs cumulative, pre-reg anchors alongside; surfaces gate crossings, never acts on them — the healthy/anomalous/escalate call stays with the session per charter §6). Conversational window 00:50–00:59Z: truncation scare was the owner’s phone rendering — message verified intact server-side via API re-fetch (1.3k chars < 2k limit), no helper bug; owner off to bed 00:58Z (“keep an eye on the runs”).

Headline mapping: our sequential FAST-AR-trunk → frozen-trunk flow expert is “extreme KI”; the two dials where PI’s production recipe differs are now named #4 arms for the Molmo2 endpoint (all-layer KV reads vs our 3 export streams; trunk CE continuing under stop-grad vs hard freeze — naive joint training costs ~65 pts language following + 7.5× convergence in their measurements). Our +0.462 aux-off result externally replicates π0.5’s Implicit-HL finding, and their untested-here runtime increment became a new zero-training rung-(a) probe banked in #6: self-generated subgoal → [subgoal|…] → panel vs 5.8026 (validity table first). #16 north star gets its external anchor (Fig. 8: held-out-home success scales with location count; 104 locations MATCHES a trained-on-test-homes control). #5 note: FAST beats naive binning ~95% vs ~85% as the backbone signal.

Session 00:14–00:3xZ: all-CPU, 0 GPU-h — the #21 review deliverable (owner-prioritized, exploit-side infra); lit slice skipped again (bounded owner-priority item) — the balance is now ~8 h old and the next non-owner-steered session takes it.) Session 00:23–00:5xZ: all-CPU, 0 GPU-h — the lit slice WAS the work item (second application of the pattern): the queued π0.5 canon deep-read executed as the session deliverable, feeding four ideas entries and the Molmo2 stage-2 decision; slice allocation back on cadence (~8 h debt cleared). Session 01:02–01:2xZ: all-CPU, 0 GPU-h — #21 P3+P1 (owner-signed infra, exploit-side): the pre-commit gate + the babysit CLI that mechanizes every future checkpoint; both live-tested against the two running jobs.

Stale detail below is the 15:2xZ snapshot: (as of 15:2xZ: sealed eval 1.9 h; noise-draw chain 18:25Z→04:12Z ≈ 9.8 h COMPLETE; state probe ≈ 1.4 h; fairness probe ≈ 1.2 h; #18.2 flip re-bank ≈ 0.8 h ADOPTED; SnapFlow distill 08:43→13:14Z ≈ 4.5 h COMPLETE at 30k; SnapFlow endpoint-eval arc COMPLETE 13:14–15:10Z ≈ 1.8 h — draws1 5.6036/1.7039, draws10 5.3675/1.5927, draws5 5.3918/1.6056, npz addendum 14:43–15:10Z — frozen verdict PARITY-ADOPT published; local GPU idle-by-design since 15:10Z — next local GPU work only via a new pre-reg), box ~34.9 / ~34.9 GPU-h (4 arms trained ≈ 17 GPU-h + 4 chained panel evals ≈ 10 GPU-h; E4B memory smoke ≈ 0.8 GPU-h NO-LAUNCH; arm C state-dropout live since 08:10Z on GPU 0 @37,160/40k at 15:38Z (≈7.5 h so far), 0.374–0.39 s/step, in-run probe DESCENDED to 10.83–10.96@36–37k (below the 11.1–11.58 plateau band) — 40k ~16:1x–16:3xZ, reads via the pre-banked statedrop_results.py; SnapFlow @10k probe on GPU 1 ≈ 0.3 GPU-h; teacher@40k ctrl eval on GPU 1 13:02–13:47Z ≈ 0.75 GPU-h COMPLETE — 7.1041/2.0720 INSIDE the Amendment 1 band; GPUs 1–3 otherwise idle by design — reserved for the arch-batch launches at the arm-C boundary per the posted pre-reg + Amendments, arm A img280 first). Explore/exploit: aux-off arm B + noise-floor replicates ≈ instrument/attribution (exploit-side); explore hours proper started with the noise-draw chain (explore-side, ~9 h queued — pacing check 19:52Z says the draws-10 runs are ~5 h each, so the chain is longer/richer than planned; still 94–99% util). Literature slice: on cadence — ~20 min at 22:2xZ (VLM-redundancy + Energy Policy → Amendment 2) after the ~25 min trunk-survey slice ~19:35–20:00Z; skipped this 23:12Z session (bounded launch-prep item, slice <1 h old); then deferred 7 consecutive sessions (00:14–02:4xZ — each had a ladder-superior item with a launch-path deadline) and taken 02:4x–02:5xZ (~15 min): ReViP state-dominant-bias mechanism + state-reliance probe + state-dropout lever banked into #11/#9 — back on cadence. CPU-side: seven consecutive all-CPU sessions while both GPU chains ran (trunk survey, flow-vs-AR paired analysis, idea #2a bucketing, ideas #18.1 hardening, ideas #18.2 reseed-behind-flag, chunked backward + oracles, E4B checklist prep 23:12Z — ckpt staged

CPU parity PASS on the box without touching a GPU) — the no-idle-pauses rule in action. The #2a sim result is the rule paying off concretely: a CPU measurement REPLACED a planned GPU screen (predicted effect sub-threshold — charter §3). #18.2 keeps the pattern: the instrument break is fully implemented + pre-registered on CPU; the flip costs one token + one eval at a boundary we already visit. Sixth consecutive all-CPU session (#18.8 leakage identity assert ~21:05–21:12Z) continues it. Literature slice: ~20 min taken this session (~21:10Z real-clock, SnapFlow + LoRA-π0 — both banked into ideas #12/#16 with numbers) — standing allocation back on cadence. Seventh consecutive all-CPU session (~21:16–21:3xZ): the #16 rig-benchmark pre-reg draft — the north-star instrument is now designed and posted before the box reads that fill its slots land (skipped lit slice this session: ran <30 min ago real-clock; next session takes it). Eighth consecutive all-CPU session (~21:30–21:5xZ): the #16 instruments — plan frozen, subsets materialized + leakage-certified, wrap census clean; the benchmark can now execute the moment the box reads fill its slots, instead of losing a session to prep at the quiet boundary (skipped lit slice again: ran ~45 min ago real-clock; next session takes it). Ninth consecutive all-CPU session (~21:51–22:2xZ): the draws-fairness instrument — the owner’s live 21:49Z challenge went from in-channel pre-declaration to execution-ready (dump path + frozen probe + validated reads) before the data it needs finishes computing; the probe itself costs ~30 GPU-min instead of a ~5 h full-panel repeat (skipped lit slice: owner-steered item took the session; the slice is now two sessions overdue — next session MUST take it). Tenth consecutive all-CPU session (~22:2x–23:0xZ): the owner-picked E4B pre-reg posted before the box that will run it is even free, and the overdue lit slice TAKEN (~20 min: 2606.31382 backbone-redundancy prior banked in #17; Energy Policy 2510.12483 → the energy-score read pre-declared as Amendment 2 before its data exists) — allocation back on cadence. Eleventh consecutive all-CPU session (22:43–23:1xZ real-clock): chunked backward landed unconditionally BEFORE the smoke that decides whether it’s needed — the E4B launch path now has no CPU work left on its critical path; the pre-reg’s chunk-mean sketch was corrected by amendment before any E4B data exists (skipped lit slice: taken last session real-clock ~22:30Z; next session eligible). Twelfth consecutive all-CPU session (23:12–23:4xZ real-clock): the stage-2 sign pre-reg posted (queue’s named next item) with feasibility recon done pre-post, + the draws run-2 headline banked the moment it landed (mean-of-10 flow 5.365 beats the AR anchor 5.8026) (skipped lit slice: taken ~1 h ago real-clock; next session eligible). Thirteenth consecutive all-CPU session (23:37–00:0xZ real-clock): stage-2 sign probe executed start-to-finish — instrument written, population + oracle + escalation all inside one GPU-busy window; the expensive flow decode is cached so the proposed stage-2b amendment re-runs in minutes (skipped lit slice: taken ~1.5 h ago real-clock; next session eligible). Fourteenth consecutive all-CPU session (00:03–00:1xZ real-clock): E4B checklist item 6 — the rsync-back loop extension whose rotation rule is what keeps the E4B run from filling the local disk at ~mid-run, done and deployed before the run that needs it can even launch (skipped lit slice: taken ~1.5 h ago real-clock and this was a bounded launch-prep item; next session eligible). Fifteenth consecutive all-CPU session (00:14–00:3xZ real-clock): the lit slice WAS the work item — a targeted deep-read (SnapFlow recipe extraction + both flagged pointer reads) converted directly into the #12 SnapFlow distill pre-reg, refilling the local-GPU queue before its ~09–10Z boundary; allocation on cadence. Sixteenth consecutive all-CPU session (00:26–00:5xZ real-clock): the entire SnapFlow impl checklist (5 items) closed in one GPU-busy window, with validation gate (a) executed on the real checkpoint and the recipe diff-verified through the real parser — the run needs only a quiet GPU and the σ_draw amendment (skipped lit slice: taken last session as the work item itself; next session eligible). Seventeenth consecutive all-CPU session (00:57–01:1xZ real-clock): resume hardening (#18.4) — the enforcement landed in the ~2 h gap before the E4B 100k launch is the first run long enough to plausibly need a mid-run resume (skipped lit slice: taken two sessions ago as the work item; next session eligible). Eighteenth consecutive all-CPU session (01:19–01:4xZ real-clock): the box-batch results instrument built + four-way oracled in the ~2 h window before its own input data exists, while babysitting three of the four 40k boundaries live (A-s0 complete + eval scoring, s1/s2 through their saves) — the ~03–04Z session runs one command instead of deriving the reads under time pressure (skipped lit slice: taken three sessions ago as the work item; next session eligible). Nineteenth consecutive all-CPU session (01:39–02:1xZ real-clock): the #18.7 duplicate census — the “before trusting fine holdout deltas” gate — executed start-to-finish in the window BEFORE the box results read those deltas: 52,507 episodes fingerprinted, split breach quantified (12.2% of core panel frames), clean-core anchors banked, all on nice-19 CPU beside five live eval chains (skipped lit slice: four sessions since the 00:14Z targeted deep-read — take it next session or state why not). Twentieth consecutive all-CPU session (02:11–02:4xZ real-clock): the panel-v2 amendment — the census’s follow-on queue item closed in the window between B’s read and the controls’ reads, so the owner can steer the re-definition before the ~04Z boundary where the noise-key flip (and one bundled re-bank instead of three) becomes possible (skipped lit slice AGAIN — five sessions since 00:14Z; reason: panel-v2 was the ladder’s top unblocked item and had a real deadline at the ~04Z anchor boundary. The slice is now firmly overdue: the first session after the box results post MUST take it as its work item or a named part of one). Twenty-first consecutive all-CPU session (02:24–02:4xZ real-clock): the #18.3 Q3 tripwire noise fix — the last deep-dive integrity item standing on the SnapFlow launch path — landed with a pre-edit banked bit-exactness oracle in the window before the ~04Z control reads (lit slice skipped a sixth time; the pure-babysit stretch before ~04Z or the first post-results session takes it — that commitment stands). Twenty-second consecutive all-CPU session (02:49–03:1xZ real-clock): the state-reliance probe — last session’s lit-slice mechanism converted into a landed instrument + frozen subset + posted pre-reg within one session, designed so the intact side pools from banked npzs and the whole probe costs 1.7 GPU-h in any quiet window (lit slice: taken last session, ~25 min ago real-clock — on cadence). Twenty-third consecutive all-CPU session (05:42–06:0xZ real-clock): the σ_draw finalization amendment — the last CPU-side blocker on the SnapFlow launch closed in the window while probe arms 3–4 scored, turning five already-banked pooled numbers into both pre-registered decision bands (no GPU spent; the fairness probe’s direct measurement is the pre-declared cross-check). Lit slice skipped this session: ~35 min bounded window fully consumed by the ladder’s top item (post-processing a finished run); last slice 02:4x–02:5xZ — next session with slack takes it per the standing allocation. Session 06:03–06:3xZ: the state-probe read itself — the 02:4xZ lit slice’s mechanism went pre-reg → instrument → 4 masked runs → SUPPORTED verdict in ~3.5 h wall-clock end to end (explore-side, ~1.4 GPU-h); the freed GPU went straight to the fairness probe (instrument-side) per the mantra. Lit slice skipped again — bounded session, ladder top item; the slice debt stands at the standing ~20–30 min for the next session with slack. Session 07:20–07:5xZ: the fairness reads — the owner’s 21:49Z challenge went pre-declaration → instrument → probe → verdict in ~10 h wall-clock with every read frozen before its data existed (instrument/attribution-side, ~1.2 GPU-h incl. the crashed run); the freed GPU went straight to the #18.2 flip re-bank per the mantra, gate-asserted against the just-measured σ_draw. Lit slice skipped — bounded session fully consumed by the ladder’s top item (post-processing a finished run + the chained launch); the ~20–30 min slice debt carries to the next session with slack. Session 07:51–08:4xZ: the queue-refill work session — #9 state-dropout went instrument → oracles → pre-reg → LAUNCH in one session (arm C is explore-side, ~7.5 GPU-h queued: real mechanism story, modal outcome “within band”, tail = vision-reliant policy); the re-bank boundary was taken in-session (ADOPT, anchor 6.5997) and the freed GPU went straight to SnapFlow (explore-side, ~12–20 h) per the mantra — both GPUs left busy on explore-class arms. Lit slice: ~10 min taken in the eval-wait window (ThinkProprio + Cloak → #9/#11) — the standing debt partially serviced; balance carries. Pre-launch catch worth the surprise log: the SnapFlow launcher’s teacher-verbatim copy had silently inherited a READ-ONLY mainline wandb write target — the class fix (verify-script pins wandb_project as a named delta) is in d9dd385. Session 08:5x–09:1xZ: all-CPU while both GPUs trained — the arm-C results instrument banked before its data (the box-batch oracle-before-data pattern, third consecutive application: box-batch → state-probe → state-dropout), so the ~12:4xZ boundary read is frozen code, not judgment at read time. Lit slice skipped — bounded session, instrument was the declared queue head; the ~20–30 min standing slice carries to the next session with slack. Session 09:13–09:4xZ: all-CPU again — the SnapFlow ENDPOINT results instrument (fourth oracle-before-data application), and the pattern paid immediately: banking the reads exposed that the live launcher’s chained evals dump no npz, so the pre-reg’s per-step horizon read had no data source — the addendum npz eval is now staged instead of being improvised at the 13:2xZ boundary. Lit slice skipped — bounded session, instrument on the critical path (endpoint ~4 h out at pick time); slice debt now TWO sessions deep — the 10:2xZ probe babysit window or the first post-endpoint session MUST take it. Session 09:4x–10:5xZ: the ladder item was #18.5 (rig-rollout safety gate — CPU, landed + 274 green while both GPUs trained), and the probe-boundary duty was taken in-session: step_010000 pushed to box GPU 1 as an expert-only 1.8G rsync (backbone sha256-matched on-box — the 9G never moved), probe read banked 20 min after the save. Lit slice TAKEN (~15 min) — the two-session debt is CLEARED: the one-step fallback menu (OFP / MeanFlow-VLA / Let-It-Be-Simple) banked into #12 ahead of the endpoint read it may steer. Explore hours: the probe’s 0.3 GPU-h is explore-side (SnapFlow chain). Session 15:13–15:3xZ: the ladder item was post-processing (rung 2) — the SnapFlow results post filled from the frozen JSON and PUBLISHED (Space + Discord + owner adoption ask), closing the #12 arc public; all-CPU (local GPU idle-by-design since the npz addendum banked). Arm C babysat mid-session with a Discord poll at the checkpoint per the class fix. Lit slice skipped — bounded publish item, the 13:12Z session’s ~15 min slice is <3 h old; balance carries. Session 15:43–16:0xZ: the ladder pick was integrity debt (#18.2 default flip, rung 4, ~15 min) — then owner steering (rung 1) arrived mid-session via the babysit-checkpoint Discord poll and took the rest: eval-reports hosting + linking, delivered and verified live in ~35 min. All-CPU (arm C babysat ×2 with polls). Lit slice skipped — owner-steered session; the 13:12Z slice balance carries. Session 16:04–16:4xZ: the ladder pick was rung 3 (launching the next pre-registered run — the arch-batch boundary sequence). GPU-side: the F1 smokes spent ~0.5 GPU-h ×3 on GPUs 1–3 that were otherwise idle until the boundary (explore-side: the arch batch bills to the ≥20% budget), overlapped with arm C’s chained eval on GPU 0 — no co-location, and the boundary launch latency dropped from ~1 h (sync+verify+smoke serial) to minutes (pull+pytest only). Lit slice TAKEN (~15 min, IVRA → #15) inside the smoke-warmup window. Session 18:15–18:4xZ: the ladder pick was rung 1 (owner steering — Molmo2 WP3, confirmed 18:12Z as tonight’s critical path); all-CPU (local GPU idle by design, box GPU 0 on arm C’s chained masked eval). Babysit checkpoint taken mid-session WITH its Discord poll (class fix holding): caught the owner’s 18:18Z probe ask and the 18:34Z multi-image question, both answered in-window; the panel-eval completion was verified at the same checkpoint (masked eval alive in scan-warmup, not a stall — 0% GPU was the warmup, checked before assuming). Lit slice skipped — owner-steered critical-path session (the 16:04Z slice is <3 h old; balance carries). Explore hours: 0 GPU-h this session; WP3 is exploit-side critical path. Session 18:41–19:0xZ: the ladder pick was rung 1/2 continuation (owner-confirmed tonight critical path — WP4 assembly slice + the 18:18Z untrained-gen probe ask). GPU-side: the probe spent ~0.1 GPU-h on the otherwise-idle local GPU (inference burst, the plan’s “parity bursts” allowance — no pre-reg needed, no training). Masked eval babysat ×2 with Discord polls at boot/checkpoint/close. Lit slice skipped — critical-path session (the 16:04Z slice balance carries; tonight’s chain outranks). Explore hours: ~0.1 GPU-h, exploit-side (Molmo2 port is the owner-promoted critical path).

Session 01:19–01:4xZ: all-CPU, 0 GPU-h — #21 P2 (owner-signed infra, exploit-side): the queue became data (queue.json + queue_cli.py validate), and the new check.py commit gate caught a real stdlib shadowing bug in the first version before it landed. Lit slice skipped — owner-signed P-block in progress, slice taken two sessions ago as the work item (π0.5); balance on cadence.

Session 01:47–02:0xZ: all-CPU, 0 GPU-h — #21 P4 (owner-signed infra, exploit-side): the now.md contract itself — head entries became the four-block Status/Steering/Done/Next skeleton (this entry is the exemplar), the footer slimmed to figure + last-2 session notes with the stale mass rolled verbatim to the archive; archive_now.py –keep 3 codified at every close. Lit slice skipped — owner-signed P-block in progress (slice taken three sessions ago as the work item, π0.5); balance on cadence.

Session 02:0x–02:1xZ: all-CPU, 0 GPU-h — #21 P5 (owner-signed infra, exploit-side): the signed driver diff landed — every session prompt now carries its start time + hard-kill budget, with an end-to-end oracle (real driver, fake claude, isolated HOME). Lit slice skipped — owner-signed P-block in progress; balance on cadence.

Session 02:32–02:5xZ: all-CPU, 0 GPU-h — #21 P6 (owner-signed infra, exploit-side): pytest gpu tier landed (strict markers, check.py –gpu, oracle + README), plus unplanned run-watching: the molmo2 @5000 save stalled ~14 min pre-save — diagnosed live (py-spy on the box, all ranks healthy), resumption confirmed at step 5020. Lit slice skipped — owner-signed P-block in progress; balance on cadence.

Session 02:51–03:2xZ: all-CPU, 0 GPU-h — #21 P7 (owner-signed infra, exploit-side): home-dir & ctrl lifecycle landed, closing the full P1–P7 signed batch; box ctrl checkout stamped live (CTRL_SOURCE_COMMIT = fa3048eb), box ~ sweep held on the charter’s Loaned-compute READ-ONLY rule (owner asked). Lit slice TAKEN (~20 min, first since the π0.5 deep-read): LabVLA — a third independent group ships the KI-joint stage-2 recipe (banked to #4, feeds tomorrow’s attachment decision); Hi-VLA systematic study — explicit subgoals’ gain concentrates on long horizon, self-generated subgoals untested there (banked to #6, shapes the rung-(a) pre-reg).

Session 04:26–05:0xZ: all-CPU, 0 GPU-h — exploit-side: killed session’s leftovers verified+committed, #19 endpoint launcher prep landed (one-command endpoint read, mechanized cost gate, 10 oracles). Lit slice TAKEN (~15 min): AEGIS + Wall-OSS-0.5 → #4’s seam map now covers stop-grad / projection-repair / end-to-end corners; refill: #4 attachment-screen pre-reg draft queued.

Session 05:48–06:2xZ: all-CPU, 0 GPU-h — exploit-side: #4 attach-screen LAUNCH PREP landed (F/K one-command launchers, 70 GPU-h gate mechanized + matched 5k downshift, joint→AR-view materializer, probe-kill bars pinned; 10 oracles, check.py 433); molmo2 K1 gate CROSSED GREEN in-session (7.1652@10000 vs ≤12.0944). Lit slice TAKEN (~15 min): CoVer banked to #19; --dump-draws retention fix pre-launch.

Session 06:46–07:0xZ: all-CPU, 0 GPU-h — exploit-side: K smoke-ladder script landed (smoke_attach_k_ddp4.sh, exact K recipe, B12c6→B8c4→ B6c3 vs the 71 GiB alloc-peak gate, green writes the k_mem_ready record; ladder pinned BEFORE either arm — a downshift is matched); the attach screen’s remaining steps are all box execution. Refill: #19 selection-ceiling read script. Lit slice skipped (taken ~06:1xZ; cadence). (The 06:21–06:5xZ #20 session ran noteless — its facts are in the archived entries.)

Session 07:02–07:1xZ: all-CPU, 0 GPU-h — exploit-side: Δ_seam frozen-read script landed (attach_seam_results.py, seam-screen reads 1–5 as one command, every decision branch oracle-gated pre-data; check.py 437). Refill: draws10_t1 frozen-read script (wanted before today’s ~13:0x boundary). Lit slice skipped (taken ~06:1xZ; cadence).

Session 07:23–08:0xZ: all-CPU, 0 GPU-h — exploit-side: draws10_t1 frozen-read script landed (draws10_t1_results.py, pre-reg reads 1–5 as one command, E1–E4 + falsifier + q4 fallback all oracle-gated pre-data; check.py 437). Refill: #19 T-sensitivity rung launcher script. Lit slice taken (~15 min): TapSampling → #19 flavor list, AR-VLA → #17, representation-anchoring noted.

Session 07:48–08:3xZ: all-CPU, 0 GPU-h — explore-side: #19 selection-ceiling read script landed (selection_ceiling_results.py, exploratory record-only best-of-K ladder + selector diagnostics, oracle-gated pre-data incl. brute-force subset enumeration; check.py 437). Refill: #19 energy-score read. Lit slice taken (~15 min): LBYL → #19 5th flavor, DVAC → #1 rollout lever.

Session 08:12–08:4xZ: all-CPU, 0 GPU-h — exploit-side: #19 T-sensitivity rung launcher landed (eval_ar100k_tsens_q4_draws10.sh, record-only rung as one command; the pre-reg’s primary-inside-gate clause mechanized, 5 abort branches oracle-checked; check.py 437). Refill: #19 dT-table read. Lit slice taken (~15 min): frozen-VLA value probe → #19 6th flavor, grafting diagnostic → #4 scale caveat.

Session 08:27–08:5xZ: all-CPU, 0 GPU-h — explore-side: #19 energy-score read script landed (energy_score_results.py, exploratory record-only proper-scoring-rule AR-vs-flow read, oracle-gated pre-data incl. exact banked read-4 reproduction; check.py 437). Refill: endpoint-runbook git-audit. Lit slice taken (~15 min): LabVLA recipe adoption + Q-VGM frozen-trunk RL → #4.

Session 08:51–09:2xZ: all-CPU, 0 GPU-h — comms/lit-side (owner high-priority steering): Papers section batch 1 landed (44eb032, 8 pages / 16 papers + index tracker; 2 correction hooks banked to ideas.md from the deep re-reads; check.py 437). No lit-slice increment beyond the section itself — the whole session was the literature record.

Session 09:10–09:5xZ: all-CPU, 0 GPU-h — comms/lit-side (owner high-priority steering, batch 2): three papers pages / 13 papers landed (one-step menu, sampling-beyond-selection, state-shortcut; tracker 29 covered / 13 remaining); 3 correction hooks banked to ideas.md — incl. the #9 p=0.8 citation being a withdrawn paper’s baseline, not its method (check.py 437).

Session 09:29–10:0xZ: all-CPU, 0 GPU-h — comms/lit-side (owner high-priority steering, batch 3): four final papers pages / 13 papers landed (grounding-conditioning, action-tokenization, data-and-trunks, attachment-frontier; tracker 42/42 — retroactive backlog cleared); 7 correction hooks banked to ideas.md — incl. two citations to content not in the cited papers (check.py 437).

Updated 2026-08-07 11:48–12:0xZ (real date -u) — tick (babysit): both runs green, no new steering; queued items stay boundary-blocked → no work session chained. The babysit “+0 steps” reading at 17500 was adjudicated live: save pause, not a hang — anatomy now quantified. draws10_t1 boundary ~12:2x–12:3xZ, just past this tick’s cap → next tick is the boundary tick.

Status (babysit 11:49Z, both green, exit 0):

box molmo2 AR 40k — babysit caught the run mid-save at 17500/40k (+0 steps over the 11-min window, loss/vram None): investigated on-box rather than trusting the pause. Save anatomy, now measured: probe line 11:35:49Z → ~14 min silent ZeRO-1 gather/serialize (no dir, no log line; 3 of 4 GPUs spin 100% in NCCL sync — the idle index rotates) → step_017500/ created 11:50Z → 37,036 MB written → resumed 17520 at 11:51:28Z. Total pause ~15.5 min, and the 15000 save reconstructs to the identical timeline (resume ~10:02 + 2500×2.18 s = 11:33 ≈ the 11:35:49 probe line). Verdict: normal; the silent-gather phase is now a known signature, not an alarm. ETA refinement: 9 saves remain → ~+2.3 h on top of ~13.7 h stepping → endpoint ~08-08 morning. Probe 7.41@17500, gate margin 4.69; 18000 probe (~12:1xZ) is the watch point (≥7.5 escalates, ≤7.0 clears).
local draws10_t1 — 24512/25800, window 28.8 f/min, cumulative 33.5 f/min → ~12.8 h total, INSIDE the 24 GPU-h gate; ~0.6 h to boundary (~12:2x–12:3xZ) → frozen reads + decode microbench + leaderboard rows land next tick.

Steering: none new (read empty; history -n 5 shows only our own 10:24–10:52Z posts, no reactions; owner last at 10:04–10:1xZ — the leaderboard steering, fully executed).

Done: tick — babysit both green, exit 0; the +0-step save-pause anomaly investigated to a measured verdict (see Status); queue_cli.py validate green (depth 2, 12 open). No run_work_next (unchanged since 10:54Z): microbench GPU run waits on the draws10_t1 boundary, F-then-joint pre-reg draft opens after the seam-screen reads (~08-09+) — the boundary tick chains the work session. 11:15Z tick entry rolled to archive. No Discord post (10:52Z post current), no blog build (no reader-visible change).

Next: draws10_t1 boundary ~12:2x–12:3xZ (next tick) → frozen reads (draws10_t1_results.py) + decode microbench + leaderboard rows (that tick arms the chained session); molmo2 18000 probe watch point; endpoint ~08-08 → #19 box obligations → K smoke ladder → attachment steer window.

Updated 2026-08-07 11:37–11:4xZ (real date -u) — tick (babysit): both runs green, no new steering; queued items stay boundary-blocked → normal exit, no work session chained. draws10_t1 ~0.8 h to boundary (~12:2xZ) — boundary tick imminent.

Status (babysit 11:38Z, both green, exit 0):

box molmo2 AR 40k — 17500/40k, probe 7.41@17500 (after 7.53@17000; watch item NOT tripped — 7.41 < 7.5, so no consecutive ≥7.5 pair — but it is a second consecutive reading above the 6.6–6.9 band; 18000 probe is the watch point: a ≥7.5 there, or failure to re-enter ≤7.0 territory over the next 2–3 probes, escalates the watch). Gate margin 4.69. Window rate 21.8 steps/min includes the 17500 save pause (loss/vram None on the latest line = save/probe line at parse time — not an anomaly); underlying ~2.2 s/step → ~13.6 h + saves, endpoint ~08-08.
local draws10_t1 — 24192/25800, window 29.1 f/min, cumulative 33.6 f/min → ~12.8 h total, INSIDE the 24 GPU-h gate; ~0.8 h to boundary (~12:2xZ) → frozen reads + decode microbench + leaderboard rows.

Steering: none new (read empty; history -n 5 shows only our own 10:24–10:52Z posts, no reactions; owner last at 10:04–10:1xZ — the leaderboard steering, fully executed).

Done: tick — babysit both green, exit 0; probe watch-item adjudicated (not tripped, refined: 18000 is the watch point); queue_cli.py validate green (depth 2, 12 open). No run_work_next (unchanged since 10:54Z): microbench GPU run waits on the draws10_t1 boundary, F-then-joint pre-reg draft opens after the seam-screen reads (~08-09+) — the boundary tick chains the work session. 11:04Z tick entry rolled to archive. No Discord post (10:52Z post current), no blog build (no reader-visible change).

Next: draws10_t1 boundary ~12:2xZ → frozen reads (draws10_t1_results.py) + decode microbench + leaderboard rows (that tick arms the chained session); molmo2 probe watch point at 18000; endpoint ~08-08 → #19 box obligations → K smoke ladder → attachment steer window.

Rolled from now.md 16:3xZ tick — the 15:22–16:1xZ work-session entry, verbatim:

Updated 2026-08-07 15:22–16:1xZ (real date -u) — work session: async checkpoint saves LANDED (owner HIGH 13:58Z; e3bdc93, oracle-gated BYTE-identical, default-on for every future train run) + the checkpointing-systems lit slice with its same-session papers page; tsens q4’s first-poll gate scare adjudicated to a startup artifact (measured ~3.3 h/rung, well inside the 12 GPU-h gate); molmo2 green.

Status (babysit 15:52Z):

box molmo2 AR 40k — 23140/40k, loss 3.0727, 2.165 s/step, vram 67.07 ≤ 71, 25.5 steps/min window. Probe 5.97@22500 (NEW LOW) → 6.05@23000. Gate margin 4.93. ~10.1 h stepping + saves → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — 832/4301 @ 21–27 f/min (four timestamped inter-batch measurements 15:20→15:44 + babysit windows). The 15:22Z babysit surfaced a 19.3 h > 12 GPU-h gate crossing — adjudicated startup artifact (cumulative rate was contaminated by the ~6-min model-load before the first progress line); measured projection ~3.3 h/rung → ~10 GPU-h for all three rungs, gate PASS. Rung roll t0.5 → t0.7 ~18:3xZ (repoint the babysit log stem at the first tick after the roll); all rungs complete ~01:0xZ 08-08 → the queued dT-read item opens.

Steering: none new (polls 15:22 / 15:45 / 15:52Z all clean; 15:46Z landing post + this close post are ours).

Done: this session — (1) async-checkpoint-saves (e3bdc93, the queue’s owner-HIGH item): bijou/async_save.py + train.py refactor. Root cause measured-then-fixed: ~14 of the ~15.5 min/save was consolidate_state_dict serially pickling whole optimizer shards over the TRAINING NCCL group; now device→CPU capture at the boundary (seconds), background gather_object over a dedicated gloo group, exact ZRO.state_dict() merge replica, atomic .tmp-dir rename, final save joined before teardown. Default ON (--sync-save escape). Oracles (check.py 446 green): 2-rank BYTE-identity vs the consolidate path at consecutive boundaries with the gather overlapping main-thread collectives — two byte-level subtleties pinned (pickle memoization of the shared betas tuple → identity- memoized snapshot copies; gather_object de-interning rank 0’s own dict keys → keep the local capture object) — plus dir-level byte-identity, weights_only resume round-trip, crash atomicity, loud background-failure surfacing. Sync path is now atomic too. (2) Lit slice + papers page (checkpointing-systems, 6 sources): design corroborated (the CheckFreq/DataStates two-phase shape); transfers banked as #18.9 hooks (pinned-buffer reuse, save-frequency retune now saves are ~free, the data-iterator-state resume gap named); non-transfers stated honestly (memory tiers, multi-step spreading, sharded formats). ideas.md #18 item 9 + hook, papers index + SUMMARY rows. (3) Queue maintenance: async item + lit item → done; idea4-f-then-joint-prereg-draft corrected queued→blocked (its boundary needs Δ_seam); driver-background-task-guard pulled forward = next CPU item (2 kills today); refills: idea19-tsens-dt-read-execution (opens at rungs completion), validate green depth 2.

Next: queue_cli.py next → driver-background-task-guard (mechanize the turn-completion teardown fix — 2 GPU runs killed by it today; run_work_next armed, next tick chains into it). Dated boundaries: tsens rung roll ~18:3xZ (babysit stem repoint) → rungs complete ~01:0xZ 08-08 (dT read, record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window — first save of that launch validates the async path in production: look for the captured in Xs + saved ... (async, Xs behind the boundary) lines at first babysit.

Rolled footer session notes (older than last-2), verbatim:

Session 13:04–15:2xZ: work session, ~2 GPU-h local (microbench redo + post-merge reruns) + tsens launch — exploit/infra + owner-comms heavy: merge chain end-to-end (pre-merge baseline banked, merge 85cdc0a with review fixes, 9.1×/2.5× single-stream speedups measured, leaderboard measured-⏱ rewrite + row 5, review post live), Ideas refactor + tags + archive sort (owner 13:02/13:26Z), charter codification, async-ckpt queued HIGH (owner 13:58Z), tsens q4 launched at the freed GPU (gate PASS 12.7≤24).

Session 09:49–10:3xZ: all-CPU, 0 GPU-h — exploit/instrument + owner-steered comms: #19 dT-table read script landed (tsens_dt_results.py, record-only per the pre-reg sensitivity clause; oracle PASS pre-data incl. exact T=1.0 re-pool reproduction

11 guard aborts); then owner steering 10:04Z executed live — Ledger → Leaderboard (evergreen scoreboard incl. the mean-of-10 teacher/student rows + measured compute column) and the slow-molmo2-saves question answered with on-box facts (37 GB/save → save-pause-aware ETA). Refills: attachment-frontier lit slice + decode-cost micro-benchmark prep (check.py 437).

Session 10:1x–10:5xZ: all-CPU, 0 GPU-h — instrument/lit-side (chained): endpoint-runbook git-audit executed CLEAN at HEAD 3d9e2a2 (zero mismatches/fix items across the whole blocked endpoint chain — stems, flags, gates, pgrep patterns all byte-match landed code); leaderboard decode micro-benchmark PREP landed (leaderboard_decode_microbench.py, 7 configs × batched/single, --selftest oracle PASS + posted pre-reg); APT 2606.12366 deep-read

init-thread siblings (VLM4VLA 2601.03309, 2605.25802) — two papers pages live same-session, #4 gains the named F-then-joint escalation rung + the F-loses vision-first diagnostic, #17 gains a trunk-screening criterion (check.py 437).

Rolled from now.md 16:5xZ tick — the 16:34–16:4xZ tick entry, verbatim:

Updated 2026-08-07 16:34–16:4xZ (real date -u) — tick (babysit): both runs green, no steering, no incident — first clean poll since the driver guard landed (compliant tsens unit, no DRIVER-CGROUP line).

Status (babysit 16:34Z):

box molmo2 AR 40k — 24260/40k, loss 3.0276, 2.172 s/step, vram 67.07 ≤ 71, 25.7 steps/min window. Probe 6.86@24000 (in-band, no ≥7.5 pair). Gate margin 4.93. ~9.5 h to 40k → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — 992/4301 @ 51.3 f/min window, cumulative 27.4 f/min → ~2.0 h remaining, projection 2.6 ≤ 12 gate. Window rate is running well above the earlier ~25 f/min measurements — rung roll t0.5 → t0.7 may land ~18:3xZ, earlier than the 19:4x estimate; repoint the babysit log stem at the first tick after the roll. All rungs still ~00Z 08-08.

Steering: none (read: only our own 16:34 close post; history: no reactions).

Done: tick — babysit both green exit 0; queue_cli.py validate green (depth 2, 12 open); run_work_next already armed 16:32Z — the chained work session follows this tick (GPUs busy, CPU items queued: save-cadence prep). 15:22 entry + 3 older footer notes rolled to archive. No Discord post (16:34 close current), no blog build (no reader-visible change).

Next: chained work session → next CPU queue item; tsens rung roll ~18:3x–19:0xZ (babysit stem repoint) → all rungs ~00Z 08-08 → dT read against the papers page’s written prior (record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production). Every GPU launch goes through run_detached.sh.

Rolled from now.md 16:5xZ tick — the 16:06–17:3xZ work-session entry, verbatim:

Updated 2026-08-07 16:06–17:3xZ (real date -u) — work session: driver-background-task-guard LANDED (96522b9, the item that killed 3 GPU runs in one day) — four live-verified defense layers: run_detached.sh required launch wrapper, KillMode=process on the tick service, babysit DRIVER-CGROUP surfacing at every poll, post-session cgroup guard with Discord alert; the kill signature is now reproduced in tests with real transient units. Plus the standing lit slice with same-session papers page (decode-temperature) — a written directional prior for tonight’s dT read. Both runs green.

Status (babysit 17:20Z):

box molmo2 AR 40k — 24180/40k, loss 3.009, 2.16 s/step, vram 67.07 ≤ 71, 25.1 steps/min window. Probe 6.86@24000 (in-band, no ≥7.5 pair). Gate margin 4.93. ~9.5 h to 40k → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — 832/4301 @ 44.6 f/min window, cumulative 25.1 f/min → ~2.9 h/rung, ~2.3 h remaining on t0.5. The 16:06 boot-poll “18.5 h” gate crossing was the startup artifact again (model-load contaminating a 2-min cumulative) — adjudicated CLEAN, projection now 2.9 ≤ 12. Rung roll t0.5 → t0.7 ~19:4xZ (repoint the babysit log stem); all rungs ~00–01Z 08-08.

Steering: none new (polls 16:06 / 16:44 / 17:20Z all clean).

Done: this session — (1) driver-background-task-guard (96522b9, owner 13:05Z item, 3 incidents’ evidence consumed): fontaine/scripts/run_detached.sh = the codified REQUIRED wrapper for any job that must outlive a session (systemd-run –user + PATH/HOME setenv + a grace-window launch-death check that surfaces the exit-127 class); KillMode=process on fontaine-tick.service (installed symlink = repo file, daemon-reload applied — noncompliant launches survive unit stop as stragglers instead of dying silently); babysit now surfaces DRIVER-CGROUP at every poll when a registered run’s processes sit inside the driver cgroup — fires BEFORE the kill; two self-match false-positive classes were found live and excluded (probe ancestor chain; the | sort -u pipeline fork inheriting the pattern-bearing cmdline); driver_guard.py post-session cgroup scan wired into the driver with a 1-h-cooldown Discord alert. Driver test: tests/test_driver_guard.py reproduces the incident-3 kill live (default KillMode kills a setsid child; KillMode=process spares it; a run_detached job survives parent-unit teardown), plus fake-/proc scan oracles + unit-file regression guard; babysit oracles extended and both directions verified live on the running tsens run (decoy straggler → SURFACED; compliant unit → clean). check.py 460 green. Charter harness section, memory file, and 6 local launcher headers codified. (2) Lit slice + papers page (decode-temperature, 5 sources): the dT read now has a pre-written directional prior (near-flat table with asymmetry against T=1.3 on a unimodal-dominated panel — 2605.22493’s deterministic-beats-generative-on-unimodal result + MARS); BOKBO banked as the second independent strike on cheap probe selectors (#19 selection rung); the q-token+CE trunk gains its sample-complexity-optimality citation (2603.20538); DDVLA’s temperature-schedule hook parked (verified at source: 97.4 decay vs 96.4/96.2 fixed/argmax — the search digest misquoted it). (3) Queue: driver guard + lit slice → done; refill attach-launch-save-cadence-prep (the #18.9 hooks become the attach launchers’ save-every call); validate green depth 2.

Next: queue_cli.py next → idea19-tsens-dt-read-execution (opens at rungs completion ~00–01Z 08-08; the read now lands against the papers page’s written prior). Dated boundaries: tsens rung roll ~19:4xZ (babysit stem repoint t0.5 → t0.7) → rungs complete ~00–01Z 08-08 (dT read, record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production; save-cadence prep item now queued for that launch). Every GPU launch from here goes through run_detached.sh.

Rolled from now.md 16:5xZ tick — the 15:22–16:2xZ footer session note, verbatim:

Session 15:22–16:2xZ: all-CPU work session, 0 GPU-h new (tsens + molmo2 accruing under their own gates) — exploit/infra + sanctioned lit: async checkpoint saves landed oracle-gated (owner HIGH, e3bdc93, byte-identical keystone on a live 2-rank group; ~14% wall-time payoff targeted at the attach screen) + the checkpointing-systems lit slice with same-session papers page (6 sources; pinned-buffer + save-frequency hooks banked to #18.9); tsens first-poll gate scare adjudicated to startup artifact (measured ~3.3 h/rung, PASS); queue: 2 done, 2 refilled, driver guard pulled forward.

Session 16:06–17:3xZ: all-CPU work session, 0 GPU-h new (tsens + molmo2 accruing under their own gates) — exploit/infra + sanctioned lit: driver-background-task-guard landed (96522b9, 4 defense layers, kill signature reproduced in tests with live transient units; the 3-incidents-in-one-day class is mechanized away) + the decode-temperature lit slice with same-session papers page (5 sources; dT directional prior + 2nd probe-selector strike banked to #19); tsens boot-poll gate scare adjudicated startup artifact (measured 2.9 h projection ≤ 12); queue: 2 done, 1 refilled.

Updated 2026-08-07 16:37–16:5xZ (real date -u) — work session: attach-launch-save-cadence-prep LANDED (c4555d4: both attach launchers --save-every 2500 → 1250 matched + pre-reg amendment 2; pinned-buffer refinement deliberately deferred) + the standing lit slice with same-session papers page (offline-validation — our panel’s metric class measured at ρ −0.61 vs rollout success; a cheap critical-frame re-pooling screen banked to #16). Queue refilled to depth 3. Both runs green.

Status (babysit 16:50Z):

box molmo2 AR 40k — 24700/40k, loss 3.034, 2.172 s/step, vram 67.07 ≤ 71, 30.1 steps/min window. Probe 6.81@24500 (in-band, no ≥7.5 pair). Gate margin 4.93. ~9.2 h to 40k → endpoint ~08-08 morning.
local ar100k_tsens_q4 rung t0.5 — 1472/4301 @ 30.1 f/min window, cumulative 28.1 f/min → ~1.7 h remaining, projection 2.6 ≤ 12 gate. Rung roll t0.5 → t0.7 ~18:3xZ (repoint the babysit log stem at the first tick after); all rungs ~00Z 08-08.

Steering: none (polls 16:37 / 16:45 / 16:50Z all clean).

Done: this session — (1) attach-launch-save-cadence-prep (c4555d4, queue item from the #18.9 checkpointing hooks): both attach-screen launchers now save every 1250 (was 2500) — async saves (e3bdc93) removed the step-stall side of the trade, so halving the interval halves worst-case driver-kill recovery loss (~108 → ~54 min wall at K’s est rate; 3 kill incidents on 08-07 made that concrete) for seconds of capture stall and ~40 GB/extra K save vs 6.3 T free on the box (F saves small — frozen backbone hardlinks). Every posted judgment boundary (5000/7500 kill evals, 10k endpoint, 5k-downshift matched read) stays a save boundary; matched BOTH arms, seam still the only contrast. Codified as pre-reg amendment 2 (operational, pre-launch) on the attach-screen post; prepared babysit entries updated. Pinned-buffer refinement (DataStates) DEFERRED — capture stall is seconds against a ≥26-min interval (<0.2% overhead); not worth touching the oracle-gated save path the day before a 50–70 GPU-h screen. Stays banked on #18.9. check.py 460 green. (2) Lit slice + papers page (offline-validation, 5 sources): the proxy question under the whole leaderboard, measured — CI-MSE (2606.29898) puts raw validation MSE at Spearman −0.61 vs rollout success over 27 VLA checkpoints, with a sign-flip case (data-scale family ranked backwards); their repair (critical-frame pooling + rollout-like alignment) reaches −0.87. Transfers banked: a CPU-only critical-frame re-pooling screen over existing npz dumps (aux labels give us the critical frames CI-MSE pays a VLM for) → new queue item; MMRV as the metric for any future proxy-vs-rig audit; the collector-mismatch caveat for future rig eval sets. Non-flip humility clause written into the page (their sign flip is not evidence ours flips). (3) Queue: save-cadence prep → done; refilled idea16-critical-frame-repooling + idea1-golden-ticket-prereg-draft (both CPU, GPU-busy-window class); validate green depth 3.

Next: queue_cli.py next → the queued CPU items (critical-frame re-pooling pre-reg, golden-ticket pre-reg draft) in GPU-busy windows; idea19-tsens-dt-read-execution opens at rungs completion ~00Z 08-08 (reads land against the decode-temperature page’s written prior). Dated boundaries: tsens rung roll ~18:3xZ (babysit stem repoint t0.5 → t0.7) → rungs complete ~00Z 08-08 (dT read, record-only); molmo2 endpoint ~08-08 morning → #19 box obligations → K smoke ladder → attach-screen window (first save validates async ckpt in production, now at 1250 cadence). Every GPU launch goes through run_detached.sh.

Session 16:37–16:5xZ (footer note, rolled 17:5xZ): all-CPU work session, 0 GPU-h new (tsens + molmo2 accruing under their own gates) — exploit/infra + sanctioned lit: attach-launch-save-cadence-prep landed (c4555d4, save-every 2500→1250 both arms + pre-reg amendment 2; pinned-buffer deferred with stated arithmetic) + the offline-validation lit slice with same-session papers page (5 sources; panel proxy measured ρ −0.61, critical-frame re-pooling rung banked to #16); queue 1 done, 2 refilled, depth 3.

Session 17:47–18:0xZ: all-CPU bounded work session, 0 GPU-h new (tsens + molmo2 accruing under their own gates) — queue-refill/ pre-reg: #1 golden-ticket screen pre-registered (design + nulls frozen entirely from banked data; staged kill line before any full-panel spend); queue 1 done + instrument/execution items added, depth 2.

Blog pushed, check 460 green. Note: the 18:24–18:4x work session (amendment 1 + seed/rewarmup reply) hit the hard cap before committing its last edit — its Discord posts are the record; the edit landed here.

Session 19:38–19:4xZ (footer note, rolled from now.md): quiet babysit tick, 0 GPU-h new (tsens + molmo2 accruing under their own gates) — both runs green (molmo2 28380/40k probe 6.88@28000; t0.7 2112/4301, zero-window judged flush quantization against the log mtime); no steering, no reactions.
