Now archive — 2026-08-11

Aged entries rolled out of now.md verbatim (newest first).

Updated 2026-08-11 17:38–18:2xZ — work session: sim-review CLOSED (owner sim-pivot head item): findings post + two committed probes; the contact-physics complaint is confirmed and mechanism-attributed.

Status: no live jobs — GPU 0% / 0 MiB (probe renders only, seconds each; inference-only steer respected).

Steering: owner 17:28Z (“killall claude to get you to focus”) — acked in-channel 17:43Z; no other new messages. Sim pivot is being executed in queue order.

Done: sim-review CLOSED (f14948f): findings post + committed probes sim/probe_benchy_contact.py + sim/probe_phantom_volume.py. Contract seam ALL GREEN (camera-kind tags match training — the judge stamped the rig’s “front” key as kind top; kind-sorted image order identical; stats/joints/degrees line up; measured bit-identical qpos AND renders; 26.9 ms/tick ⇒ ~20 min sim-side per 100-seed eval). Four findings, fixes deliberately not executed (findings-first): (1) home pose UNREACHABLE — wrist-cam mount collision box jams into the shoulder, three servos force-saturated, elbow −19° steady-state, wrist_roll bimodal per seed; (2) 2/20 seeds the arm strikes the boat during the reset settle (≤30 mm pre-episode); (3) benchy phantom collision margin p99 3.8 / max 5.4 mm (74% of the collision surface outside the visible boat); (4) jaw torsion weak — gripper priority=1 overrides the benchy drift-fix friction at the grasp seam (6.9° in-grip spin, tilt to 0.84 upright on lift); rest drift 0.000 mm. Infra: menagerie commit unpinned + per-machine CoACD assets ⇒ pin one eval machine in the protocol; EGL runtime installed on this box.

Next: queue_cli.py next → sim-lit-review (owner-sanctioned sim lit lane, Papers pages same-session); sim-policy-eval-100seeds protocol pre-reg is now draftable but must fold in findings 1–2 fixes first. rig-mixture-screen-exec stays owner-held (🅰️-vs-🅲). run_work_next armed. No dated boundaries — queue.json canonical.*

Updated 2026-08-11 16:26–16:3xZ (real date -u at write: 16:27) — tick (babysit): quiet tick — GPUs free, 👍 reaction on the ER-init long-form recorded, run_work_next ARMED for rig-mixture-instrument-prereg.

Status: no live jobs — registry empty, nvidia-smi 0% / 0 MiB. git ls-remote origin main still fdd9aa3 → rebase-fontaine-on-main-postreview stays BLOCKED on the owner-side push; re-check every boot.

Steering: read empty; history -n 5 shows a new 👍 on our 16:24Z ER-init long-form post — lightweight owner agreement with the screen close + the named next lever (rig-mixture), recorded per the 08-05 reaction protocol. No reply owed (reaction on our own result post).

Done: queue validate OK (depth 2, 9 open). run_work_next ARMED 16:27Z — next item rig-mixture-instrument-prereg is executable CPU but work-session-class (loader --dataset-repeat instrument + oracle test + mixture-screen pre-reg draft, not a 30-min-tick job); GPU-busy-window rule N/A (GPUs idle-by-design, no launchable GPU item — the mixture GPU leg pends the owner compute call). 13:53 entry + 16:03/13:53 footer notes rolled to the archive.

Next: chained work session executes rig-mixture-instrument-prereg; its pre-reg draft must name the compute ask (local 1×H100 rung vs a new box) and hold for owner steering. Rebase unblocks the moment origin/main moves past fdd9aa3. No dated boundaries — queue.json canonical.*

Updated 2026-08-11 16:07–16:4xZ (real date -u at write: 16:28) — work session (chained via run_work_next): er-screen-results-post CLOSED — the durable ER-init long-form is live with 3 house charts; queue refilled to depth 2; box housekeeping done.

Status: no live jobs — registry empty, nvidia-smi 0% / 0 MiB. git ls-remote origin main checked at boot: still fdd9aa3 → rebase-fontaine-on-main-postreview stays BLOCKED on the owner-side push.

Steering: none — read empty at boot, no owner traffic since 14:55Z (answered last session).

Done: er-screen-results-post CLOSED — posts/2026-08-11-er-init-screen-results.md: plain-words opener, probe overlay rebuilt from the salvaged box train logs (mean matched-step Δ −0.45 from 20k on, run-best 5.10@44500), panel rung trajectory (+1.52 → +0.28 → −0.18 → −0.23), decision-CI figure (−0.2297 [−0.281, −0.154] vs 40k; −0.0821 [−0.126, −0.025] vs 60k-cont), aux-heads table across rungs; chart script er60k_screen_close_charts.py reads only banked files; all artifact links curl-verified; check.py green (667). Index drift fixed: four 08-10 posts were missing from posts/index.md. Status audit: er-60k-live queue item was still status=live → done. Box git remote dropped. Queue refilled to depth 2: rig-mixture-instrument-prereg (executable CPU) + ae-on-our-trunk-prereg-draft (pends the rebase).

Next: queue_cli.py next → rig-mixture-instrument-prereg (per-root --dataset-repeat + oracle test + mixture-screen pre-reg draft on er_60k/step_060000; GPU leg pends the owner compute call — the 4× box is gone). Rebase unblocks the moment origin/main moves past fdd9aa3 — check at every boot. No dated boundaries — queue.json canonical.*

Updated 2026-08-11 10:00–13:5xZ (real date -u at write: 13:33) — work session (chained, owned the er55k eval + the box endpoint): THE ER DECISION READ LANDED — ER init WINS both legs; er_60k run CLOSED at ~153/155 GPU-h; two owner exchanges answered in-session; events one-off queued.

Status: no live jobs — both GPUs FREE (first time since 08-09). fontaine_molmo2_er_60k_ddp4 COMPLETE: train @60000 12:36Z + chained panel_v2 eval rc 13:28Z; babysit registry empty.

Steering: OWNER 11:56Z (their AE impl off our AR trunk, every-layer KV) — ANSWERED 12:38Z (port supports it directly: shared trunk loader, per-layer KV cache, 4 pre-reg decisions named); owner 12:44Z says they’ll do the main changes locally, wants a ping when 60k lands (DONE 13:32Z). OWNER 12:03Z (aux vs 60k-cont) — ANSWERED 12:38Z (table: holding er-better +2.3, event cont-better +2.3, progress/visible tied). OWNER 12:44/12:45Z (events one-off report, many varied examples + constrained-decode probe) — plan ACKED in-channel 12:51Z, queued er60k-events-oneoff-report, next session’s first item.

Done: er55k-panel-eval CLOSED (rc=0 12:00Z ~2.2/8 GPU-h; 5.8269 core, first BELOW-baseline ER read −0.181 vs 40k endpoint; parity with 60k-cont; posted 12:0xZ; fdd9aa3). er60k-endpoint-postprocess CLOSED (this commit): endpoint 5.7782/1.9898 core; vs 40k endpoint −0.2297 [−0.281, −0.154]; vs 60k-cont −0.0821 [−0.126, −0.025] — BELOW-BASELINE both legs, CI excludes zero = ER init wins, new reference trunk; rung trajectory +1.52 → +0.28 → −0.18 → −0.23; rig-data read not split-compatible (no owner-rig repos in the panel, skipped per pre-reg if-clause); step_060000 weights → fontaine-checkpoints (42.0s, 4ed3dd0); reports + decision JSON on fontaine-reports (curl 200); chart-led post + owner ping 13:32Z. Boot audit: orphaned queue.md regen committed (151a861).

Next: queue_cli.py next → er60k-events-oneoff-report (owner 12:44Z: model-vs-gt event confusion + galleries + none-banned constrained-decode probe on @60000; needs the narrated-arm generations dump first — instrument gap pinned at bijou/eval/cli.py results.generations). Then: ER results post (chart-led screen close, deliberately rolled); their-AE-on-our-trunk pre-reg pends the owner’s main-changes ping. No dated boundaries pending — queue.json canonical.*

Updated 2026-08-11 09:32–09:3xZ (real date -u at write: 09:35) — tick (babysit): quiet green tick — no boundary in this window, box healthy, owner quiet; next event is the endpoint itself.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — babysit exit 0 at 09:32 (count 55,060 @ 25.5 f/min, 8 procs, util 55–83% at sample w/ refill dips, vram ~71.8×4 under the 77 bar), gate projection 138.8/155 GPU-h. No new rungs since the @55000 close (5.35@55000 last; 5.1–5.6 band holds, run-best 5.10@44500 stands; next rung @55500 ~09:5xZ). No save boundary in this tick’s window — the next boundary IS the endpoint @60000 ~12:4xZ (4,940 steps at 25.5 f/min ≈ 3.2 h) → chained panel_v2 = the ER decision read. Local H100 FREE.

Steering: none — read empty ×2 (boot + babysit’s built-in poll), history -n 5 shows only the answered 08:40/08:41Z exchange, no new reactions. Owner quiet since 08:41Z.

Done: babysit exit 0; queue validate OK (depth 1, stated reason carries); 09:00 entry + footer note rolled to the archive; blog build + Space push (now.md is reader-visible).

Next: endpoint @60000 ~12:4xZ → the endpoint-window tick arms run_work_next for er60k-endpoint-postprocess (ride the chained panel_v2 to rc, paired CI95 vs banked 40k 6.0079 + 60k-cont 5.8602). run_work_next again deliberately NOT armed: depth-1 stated reason (refill pends the ER decision read), only open item time-gated ~3 h out — judgment re-recorded per charter §6.*

Updated 2026-08-11 09:00–09:0xZ (real date -u at write: 09:01) — tick (babysit): quiet green tick — box healthy, owner exchange closed, orphaned queue-page regen committed.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — count 54,260, 27.1 f/min window, babysit exit 0 (8 procs, util 66–99% w/ refill dips, vram ~71.8×4 under the 77 bar), gate projection 136.7/155 GPU-h. Rungs since last tick: 5.23@54000 — 5.1–5.6 band holds, run-best 5.10@44500 stands. Next save boundary @55000 ~09:2x–09:3xZ lands at this tick’s cap edge → next tick owns it (no kill line active, record-only to endpoint). Endpoint @60000 ~12:3xZ → chained panel_v2 = the ER decision read. Local H100 FREE.

Steering: none new. read surfaced only our own 3-post series (cursor advance); history -n 5 shows the owner’s 08:40/08:41Z questions (answered 08:46–08:48Z) + our replies, no new reactions. Owner quiet since 08:41Z (~20 min at poll) — conversational mode closed, back to tick cadence.

Done: orphan audit part 2 — the 08:36 tick committed the item-4 queue.json close but left the regenerated queue.md blog page uncommitted (Updated-stamp 07:15Z matches the committed queue state; faithful regen, committed this tick). Babysit exit 0; queue validate OK (depth 1, stated reason carries); blog build + Space push (queue page + now are reader-visible); 04:21 entry rolled to the archive.

Next: @55000 boundary → next tick (~09:3xZ); endpoint ~12:3xZ → the endpoint-window tick arms run_work_next for er60k-endpoint-postprocess (ride the chained panel_v2 to rc, paired CI95 vs banked 40k 6.0079 + 60k-cont 5.8602). run_work_next again deliberately NOT armed: same depth-1 stated reason (refill pends the ER decision read), the only open item is time-gated ~3.5 h out — judgment re-recorded per charter §6.*

Updated 2026-08-11 08:36–08:5xZ (real date -u at write: 08:44) — tick (babysit): first surviving session after a 07:09–08:25Z out-of-credits outage — orphaned item-4 close committed on the dead work session’s behalf, owner question answered in-channel, box green.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — count 53,640, 26.8 f/min window, babysit er_60k green (8 procs, util 68–99% w/ refill dips, vram ~71.8×4 under the 77 bar), gate projection 135.2/155 GPU-h. Rungs since @50000: 5.28 / 5.31@50500 / 5.26@51000 / 5.42@51500 / 5.44@52000 / 5.42@52500 / 5.22@53000 / 5.35@53500 — 5.1–5.6 band holds, run-best 5.10@44500 stands. Next save boundary @55000 ~09:2xZ (tick-owned); endpoint @60000 ~12:3xZ → chained panel_v2 = the ER decision read. Local H100 FREE (AE run complete 06:56Z).

Steering: live owner exchange on the MolmoAct2 port. 08:36:12Z (sent twice): “Is there a separate training script for molmo2act vs molmo2/e2b in our repo?” — answered 08:37:49Z (yes: bijou/train.py = OUR trunk-agnostic flow-matching recipe; bijou/molmoact2/train.py = THEIR recipe verbatim, kept separate on purpose, 2 pre-declared deltas). Follow-ups 08:39–08:41Z: (a) is the architecture shared / checkpoints same format, (b) in-depth overview of what’s implemented, (c) step-by-step recipe diff vs our usual training — answered in a 3-post series 08:46–08:48Z (trunk = same bijou/molmo2 code with their weights drop-in, experts = separate architectures, checkpoints = two families but ours↔theirs interchangeable within molmoact2; the 5-module package walkthrough with parity results; 10-point recipe diff incl. the noise-fraction-law-identical timestep observation and the dropout-delta fingerprint). Quiet from 08:41Z through session close (~14 min) — hand back to tick cadence; next session rejoins via history if the thread continues.

Done: credits-outage post-mortem + orphan audit. The 04:24 work session closed port item 4 (G4 PASS posted in-channel 07:08Z: all four frozen clauses on the 240 anchor rows, final rung 4.8846, ~1.9/6 GPU-h, port total ~2.6/8, step_002000 uploaded; record-only +1.65 rung gap vs their-trainer = trunk-dropout delta fingerprint, named lever) but died on out-of-credits 429 at 07:09Z after its final queue update and before its commit; every tick 07:19–08:25Z died at startup on the same 429 (2 harness alerts in-channel; alert throttling ate the rest). This tick committed the orphaned queue.json (item 4 → done, depth-1 stated reason), pruned the finished molmoact2_ae_ours babysit entry (the exit-1 liveness fail was the finished-run artifact — er_60k itself green), and rolled the 03:24 entry to the archive. Credits flowing again as of 08:36Z; run never affected.

Next: @55000 boundary ~09:2xZ (next tick); endpoint ~12:3xZ → the endpoint-window tick arms run_work_next for er60k-endpoint-postprocess (ride the chained panel_v2 to rc, paired CI95 vs banked 40k 6.0079 + 60k-cont 5.8602). run_work_next deliberately NOT armed this tick: queue depth 1 carries the prior session’s stated reason (refill pends the ER decision read), the only open item is time-gated ~4 h out, and holding a work session across that window right after a credits outage is the wrong spend — the judgment is recorded here per charter §6.*

Updated 2026-08-11 03:20–03:2xZ (real date -u at write: 03:28) — tick (babysit): quiet green tick minutes after the 03:2x work close — box healthy, nothing new on the channel; run_work_next confirmed armed for the chained work session.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — count 45,160, babysit exit 0 (8 procs, util 67–99%, vram ~71.8×4 under the 77 bar), gate projection 114.0/155 GPU-h. Probe unchanged since the close (latest 5.41@45000; run-best 5.10@44500 stands; 5.1–5.6 band). The window printed 0.0 f/min — a 36-s baseline artifact (the closing session’s 03:19:45 poll reset it); count advanced 45,040→45,160 since 03:15, ~27/min class, no starvation. Record-only to endpoint @60000 ~12:3xZ → chained panel_v2; next save boundary @50000 ~06:2xZ. Local H100 FREE. Blog Space 403.9 MB (pushed + squashed 03:18).

Steering: none — read empty; history -n 5 shows only our own five posts, no new reactions.

Done: babysit exit 0; Discord read (empty) + history (clean); queue validate OK depth 2 (9 open); run_work_next confirmed armed (03:19 marker un-consumed — the chained work session is still ahead); aged 08-11 entries + footer notes rolled to archive.

Next: unchanged from the 03:2x close — chained work session opens molmoact2-firstclass-port item 3 (contract pinned in the queue item); box endpoint @60000 ~12:3xZ → chained panel_v2 → paired CI95 vs banked 40k (6.0079) + 60k-cont (5.8602) = the ER decision read; er60k-endpoint-postprocess queued for that window.*

Updated 2026-08-11 00:50–03:2xZ (real date -u at write: 03:16) — work session (chained): port item 2 FULLY CLOSED — action-side processing byte-exact vs their shipped lerobot pipeline + the @45000 boundary ridden in-turn (capture 21.6 s green, run-bests 5.20@44000 → 5.10@44500) + blog-Space GC finally under the line → one-shot book push done.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — count 45,040, 25.4 f/min window, 113.7/155 GPU-h, babysit exit 0 ×5 this session (8 procs, util 54–100%, vram ~71.8×4 under the 77 bar). @45000 save boundary caught in-turn 03:15Z: capture 21.6 s green, async publish 154.7 s behind (steady ~155 s class since @25000, record-only). Rungs since @41000: 5.58@41500 / 5.39@42000 / 5.35@42500 / 5.42@43000 / 5.41@43500 / 5.20@44000 / 5.10@44500 = new run-best (prior 5.42@41000) / 5.41@45000 — er holds a 5.1–5.6 band; 40k best-ever was 5.91. Matched legs ENDED @40000, record-only to endpoint @60000 ~12:3xZ → chained panel_v2. Local H100 FREE. Blog Space 403.9 MB (below the ~500 line — push executed, see Done).

Steering: none — Discord read empty at all five babysit polls (00:50 / 01:2x / 02:13 / 02:38 / 03:16); no new reactions.

Done: (1) Port item 2 CLOSED (71e146b) — bijou/molmoact2/processing.py: q01/q99 normalize+clamp (state in) / clamp+unnormalize (action out) in their exact lerobot formula; task- text normalization; 256-bin discrete state string; robot prompt template + chat wrap + <action_output>; resize-mode image path (their shipped crop_mode='resize': one 378×378 view/image, grid (14,14,0,0), 196 pooled tokens) with uint8-end-to-end semantics; tokenization + BOS insert; sequence-budget guard. Token-id delta pinned (molmoact2 re-homes image specials to 155648+, state/action vocab 151669+). Parity: goldens banked from THEIR real pipeline in their venv (9 input + 3 action cases, 108K fixtures) — reproduced byte-exact (max|Δ| 0.0) on ids / pixels / pooling / state / actions, uint8 resize bit-identical across torchvision 0.25/0.26; +23 CPU oracles, check.py 651 green; posted in-channel 01:3xZ. Item-3 contract pinned in the queue item (image_patch_id from config — no code change; token_type_ids bidirectional mask needs the NEW id set; G2 anchors 28.9454/3.2301). (2) Box @45000 boundary caught + posted 03:1xZ. (3) blog-space-gc-tail CLOSED: GC drained 543.6 → 403.9 MB → one-shot book push (scoped delete_patterns) + super_squash + curl-verify + all-clear post.

Next: queue_cli.py next → molmoact2-firstclass-port item 3 (end-to-end parity harness vs their HF forward + banked 240-row anchors; contract pinned in the queue item) as the next port session’s opener; box endpoint @60000 ~12:3xZ 08-11 → chained panel_v2 → paired CI95 vs banked 40k (6.0079) + 60k-cont (5.8602) = the ER decision read. run_work_next armed.*

Updated 2026-08-11 00:48–00:5xZ (real date -u at write: 00:49) — tick (babysit): quiet green tick — box healthy with a new run-best ~5.42@41000; run_work_next armed for port item 2 + the ~12:00Z endpoint.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — count 41,140, 27.6 f/min window, 103.9/155 GPU-h projection, babysit exit 0 (8 procs, 4 GPUs 80–100%, vram ~71.8×4 under the 77 bar). Rungs since @40000: 5.45@40500 / 5.42@41000 = new run-best (2dp print; prior 5.43@34500) — matched legs ENDED at @40000, everything from here is record-only to the endpoint ~12:00Z today → chained panel_v2. Next save boundary @45000 ~03:1xZ. Local H100 FREE. Blog Space 543.6 MB (re-checked 00:49 — GC plateaued since the 00:46 read, still above the ~500 line, no push).

Steering: none — read empty; history -n 5 shows no new reactions beyond the three recorded 👍s.

Done: babysit exit 0; Discord read (empty) + history (no new reactions); queue validate OK depth 2 (9 open); run_work_next confirmed armed (00:46 marker un-consumed — the chained work session is still ahead); Space usedStorage re-checked.

Next: unchanged from the 00:4xZ close — chained work session opens port item 2 (prompt template / discrete state tokens / q01-q99 norm-stats processing) and owns the @45000 boundary ~03:1xZ

Updated 2026-08-10 23:22–2026-08-11 00:4xZ (real date -u at write: 00:46) — work session (chained): port item 1 FULLY CLOSED (wiring byte-exact vs their shipped code) + the @40000 boundary caught with 20 straight negative legs + the 35k standard eval ridden to rc and postprocessed end-to-end — the owner’s 20:47Z request is closed.

Status: fontaine_molmo2_er_60k_ddp4 LIVE box 4×H100 — @40000 save boundary caught 00:0xZ (capture 21.8 s green; background publish ~154 s-class, steady since @25000 — the earlier “one-off” call was wrong, record-only since captures hold ~21 s), probe 5.5371@40000, run-best 5.43@34500 stands, 101/155 GPU-h, endpoint ~12:00Z today → chained panel_v2 = the ER decision read. Matched-delta legs vs 40k (shared seed): 20 consecutive negative — @30500–@35000 mean −0.70 (window banked late; it was never banked at the @35000 boundary) and @35500–@40000 mean −0.67; running mean over all 64 legs ≈ −0.28; matched legs END here (the 40k run stopped at 40000). Local H100 FREE since 00:41Z. Blog Space GC: 662.6 → 543.6 MB — nearly at the ~500 push line, no push yet.

Steering: none new (channel polled 23:22 / 00:05 / around each post; only last night’s three 👍s, already recorded).

Status: no live jobs — GPU 0% / 0 MiB (inference-only steer respected). Driver-guard straggler pid 35366 checked: a 6-day-old idle tmux zsh, not a job — nothing to relaunch.

Steering: no new owner messages/reactions in-channel this tick. But main moved 36afff0 → 128a863: owner design record architecture §8.13 molmo_flow (MolmoAct2 action expert as a first-class bijou decoder; 10 registered decisions incl. ascending-t convention for all new flow code, parallel copy w/ byte-parity oracle, conversion-first loading, decoder-owned q01/q99, joint_ce narration rider, --insulate-expert KI seam; steps 1–8 with gates, est. 5–6 sessions ≤10 GPU-h; “plan approved in owner session 2026-08-11; step 1 (CLI rule) next”). Treated as steering: it post-dates the 17:07Z sim pivot, so lane priority is ambiguous — asked in-channel 18:19Z (a) sims first / (b) step 1 first / (c) interleave; defaulting to (a) until answered. Tight-poll owed.

Done: (1) fontaine rebased onto main @128a863 — clean, 17 commits replayed, zero conflicts (docs-only commit; check.py 688 green via the pre-commit hook at push).

(3) Straggler triaged benign; ack + priority ask posted 18:19Z.

Next: run_work_next armed (pre-existing) — chained work session: sim-lit-review under default (a), pivoting to molmo_flow step 1 if the owner calls (b)/(c); rejoin the Discord thread via history first. rig-mixture-screen-exec stays owner-held. No dated boundaries — queue.json canonical.*

Steering: OWNER 17:07Z — next-day focus = SIMULATIONS: review sim/ first, lit review on so101-suitable sims + sim-to-real (re-opens the paused lit lane for sim topics specifically), local GPU dedicated to inference while sims run, initial goal = one good policy on 100 fixed seeds measuring boat→disk distance reduction; boat (benchy) contact physics flagged as poor. ACKED in-channel 17:36Z with the 3-step plan. (Owner 16:52Z box-deletion fyi was already acked 17:03Z by the work session.)

Done: (1) boot audit: killed session’s orphaned now.md/queue state committed (fb3e61f), hallucinated clocks corrected (~30 min fast vs file mtimes). (2) Preflight read posted 17:35Z: FITS — peak 69.2/80 GiB, ~12.0 s/step steady ⇒ 10k steps ≈ 33.5 h single-H100 (above the 14–16 h estimate); --dataset-repeat live-fired (clean 0.42% + v2 4.07% = 4.49% combined effective share vs the ~4.97% pre-reg estimate — reconcile before any exec); 🅱️ collides with the GPU-for-inference steer → rig-mixture treated as 🅲 defer unless the owner calls 🅰️. (3) Queue re-shaped: +sim-review (new head), +sim-lit-review, +sim-policy-eval-100seeds (blocked behind sim-review + protocol pre-reg); ae-on-our-trunk-prereg-draft deprioritized behind the sim lane. (4) run_work_next ARMED — chained work session starts sim-review.

Next: work session: sim-review (map sim/: so101_sim/rollout_sim/benchy scene, observation surface vs policy input contract, determinism/seeds, contact-physics investigation), then sim-lit-review. rig-mixture-screen-exec owner-held (🅰️-vs-🅲 call pending). 16:26 + 16:07 entries and their footer notes rolled to the archive.

(2) Rig-mixture pre-reg DRAFT posts/2026-08-11-prereg-er60k-rig-mixture.md: --init-from er_60k/step_060000, rig clean=27 v2=27 (~4.97% share), 10k steps seed 3; primary read = paired CI95 on the deterministic rig holdout (1+5 episodes er_60k never trained on); guard = panel non-regression +0.05 band vs banked 5.7782; compute ask (A) new 4× box ~28 GPU-h / (B) local 1×H100 after an act-ckpt fit-preflight (full recipe measured OOM single-GPU 08-08) / (C) defer. Space pushed, post curl-200, ask in-channel. (3) Main rebase CLOSED (2a31981): 11 branch commits replayed onto 36afff0, check.py 688 green, sentinels verified (released_so100_101, frozen no-default ActionExpertConfig, staticmethod factories, 5 loud guards + tests, CPU-side patch alignment, both edited fontaine scripts, tokenizer FileNotFoundError).

Done: queue validate OK (depth 1, 9 open); run_work_next ARMED 16:04Z — dual reason: next item er-screen-results-post is CPU work-session-class (chart-led long-form + Space push, not a 30-min-tick job) and depth 1 < 2 owes a refill. 10:00 entry + 13:49/10:00 footer notes rolled to the archive.

Next: chained work session: (1) er-screen-results-post — the full ER-init story, house chart style, posts/ page + plain-words opener, Space push, link in-channel; (2) queue refill to depth ≥2 (candidate: AE-on-our-trunk pre-reg draft, pends the rebase); (3) housekeeping: drop the dead box git remote.

Done: queue validate OK (depth 1, 8 open); run_work_next ARMED — dual reason: er60k-events-oneoff-report is queued executable on a free local H100 (owner one-off, gate ≤4 GPU-h, work-session-class: instrument dump → confusion quant → galleries → constrained-decode probe → HTML), and depth 1 < 2 owes a refill. 09:32 entry + the 09:42/09:32 footer notes rolled to the archive; blog build + Space push.

Next: chained work session: (1) er60k-events-oneoff-report — launch note with pinned invocation + confusion/probe spec in-channel before the GPU minute (rides the er-60k pre-reg, record-only), then the dump pass + report; (2) queue refill to depth ≥2 (candidates: ER results screen-close post, their-AE-on-our-trunk pre-reg draft — the latter pends the owner ping); (3) rejoin the owner thread via history if it re-opens.*

Steering: three exchanges, all answered in-session. (1) OWNER 14:04Z box-teardown review → full banked-vs-at-risk audit posted 14:36Z (everything decision-relevant on fontaine-checkpoints/bijou-checkpoints/fontaine-reports; 3 unbanked relics released by owner; salvage done pre-teardown), owner deleted 14:37Z. (2) OWNER 14:34Z relayed a main-agent directive (message.txt): rebase on main @36afff0 + make check.py green on artifact-less clones — the second half DONE d7b6864 (option a: frozen stage-01 analysis committed, oracle chain clone-verifiable), the rebase BLOCKED (GitHub main still fdd9aa3, 36afff0 unpushed — owner told 15:08Z; queue item rebase-fontaine-on-main-postreview holds the full adaptation list). (3) Incident owned: my poll loop ran read inside an until condition and consumed the 14:34 message unseen (4th consume-once incident, new variant; memory updated) — recovered via history, owner acknowledged.

Steering: Discord read empty at boot and at the work boundary; no new owner messages.

Done: sim-fixes-reset-contact CLOSED (commit 4cb1f70, results post sim fixes batch 1). Start state: the unreachable home pose was three layers deep — camera-mount↔shoulder exclude, wrist↔shoulder exclude, and shoulder_lift/elbow_flex ranges widened at load (menagerie couldn’t represent the rig’s median start; the 6.6° elbow residual is the jaw tip physically on the table = the reachable projection, pinned for the protocol; settled state now seed-independent <0.003°). reset() reworked spawn-after-settle with a public strike counter; a second strike channel found (jaw tips sat inside the spawn region) → near bound 0.17→0.195; 0/100 strikes, initial-distance design target preserved (mean 9.5 cm). Jaw seam: priority=2 on benchy geoms (pairs impossible — vendored jaw meshes unnamed) → in-grip spin 6.9°→0.4°, tilt 0.84→0.91. Threshold-driven CoACD (0.015, uncapped, 340 hulls): phantom p99 3.78→0.45 mm, volume 1.75×→1.13×. Regression caught: rest drift returned at 6.2 mm/10 s — root cause the vendored solver caps (ls_iterations 20) under-converging 30–80 keel–table contacts, not friction; scene sets 50/50 → 0.001 mm at unchanged 26.7 ms/tick. All gates green, check.py 688, bit-determinism re-verified.

Open-loop replay of rig episodes through the sim arm (sim/sysid_servo.py, SIMPLER’s recipe; fit train-side, validated on the er-60k episode holdout): vendored menagerie gains are the worst candidate measured — kp 998 with ±2.94 forcerange saturates at 0.17° = bang-bang servo, val arm MAE 3.31°, worse than a teleport servo (2.19° real-lag scale), sags ~19° below a commanded plateau the real arm holds; upstream kp 17.8 directionally right (2.80°); 6-param deps-free coordinate-descent fit lands 1.76° (−47%). Winner pinned as so101_sim.SERVO_SYSID (kp 108.18 / kv 13.377 / fr 3.478 / damping 0.722 / friction 0.0183 / armature 0.2045 — the big armature reads as reflected gear-train inertia). All sim-fixes gates re-verified under the new params: 0/100 strikes, settled state bit-identical across seeds, drift 0.001 mm/10 s, pinch-lift held with spin 0.1° (improved from 0.4°), determinism green, 28.0 ms/tick. Elbow residual 3.89° = unmodeled boat payload (per-joint gains the named next rung). JSON banked on fontaine-reports (curl 200). check.py 688 green; queue: sysid → done, sim-visual-matching queued, 100-seeds boundary updated (v0 physics fully pinned).

Next: queue_cli.py next → sim-policy-eval-100seeds protocol pre-reg, nothing blocking (v0 physics = widened ranges + solver caps 50/50 + 340-hull assets + SERVO_SYSID). run_work_next armed. No dated boundaries — queue.json canonical.*

Updated 2026-08-11 20:44–00:0xZ 08-12 — work session: the 100-seed sim eval ran — and answered: er_60k does NOT engage the boat in the v0 sim (0/100, mean progress −0.03 cm). Owner redirected mid-ride; phase 2 (rig-ft student, snapflow student, 80k teacher) live overnight.

Status: fontaine-sim100b LIVE on the local H100 (launched 23:44:39Z, first poll 92% util / 6.1 GiB, ~30 s/episode): 3 arms × seeds 0–99 — ftrig4k (rig-ft snapflow student, euler-1), snap30k (student, euler-1), teacher80k (artrunk@80k, heun-30); ETA ~03:2xZ 08-12, gate 4 GPU-h on the entry (phase 1 spent ~2.0 of the pre-reg 6).

Steering: owner engaged mid-ride (22:28 “how’s it going” answered by the 22:51 preliminary post; 22:58+22:59 directives): kill the rung arms, try other policies for >0 success — rig-fine-tuned first, then snapflow distilled, then the heun-30 80k teacher. Executed: unit stopped 23:41Z, phase 2 launched 23:44Z, all three picks found on local disk; replies posted 22:51 + 23:41.

Done: sim-policy-eval-100seeds pre-reg + phase 1 (commits 4d24893…cc5716b): protocol pre-reg posted + param sheet in-channel 20:58Z, objection window honored, launch 21:40Z. Instrument: rollout_sim.py --out-json/--hold/--method + stable-key noise identity; runner scripts; frozen reads sim100_reads.py (6 oracles) + house dark-mode charts sim100_charts.py (palette OKLab-validated). Phase-1 findings banked: er60k arm 100/100 episodes — mean progress_final −0.03 cm, 0/100 successes, boat untouched on 96/100 seeds; videos show confident reaching over the table but never at the boat = the visual-gap fingerprint (AutoEval per-policy-family caveat, pre-declared). Gates green: reset strikes 0/100, hold floor −0.00002 cm, ~423 ms/predict heun-10. sim-visual-matching is now THE lever for the owner’s 100-seed goal. Rung ordering read moot (arms killed).

Next: queue_cli.py next → sim100-postprocess at fontaine-sim100b rc (~03:2xZ 08-12): reads over 5 arms + report + gallery + results post; per-arm numbers in-channel as they land. run_work_next armed. No other dated boundaries — queue.json canonical.*

Session 2026-08-11 20:42–20:4xZ (tick, babysit; 0 new GPU-h — GPUs free): quiet tick. Registry empty, nvidia-smi 0%/0 MiB. Discord read empty; history clean (no reaction yet on the 20:42Z servo-sysid post). Queue validate OK (depth 2, 11 open); next = 100-seeds protocol pre-reg, nothing blocking. run_work_next already armed → pre-reg work session chains next. 18:43 body entry + 19:23 footer note rolled to the archive.

Session 2026-08-11 19:26–20:4xZ (work, exploit-infra; 0 GPU-h — CPU sim replays only): sim-servo-sysid CLOSED end-to-end — replay harness + deps-free 6-param fit (2 starts, ~240 evals each, ~40 min CPU), held-out arm replay MAE 3.31°→1.76°, SERVO_SYSID pinned into so101_sim.py, all sim-fixes gates re-verified (spin improved 0.4°→0.1°), results post + chart + json banked, sim-visual-matching queued. run_work_next armed (100-seeds protocol pre-reg next).

Session 2026-08-11 20:44–00:0xZ 08-12 (work, exploit; ~2.1 GPU-h spent in-session + fontaine-sim100b live overnight ≤ 4 gate): 100-seed sim eval pre-reg → launch → phase-1 result (er_60k 0/100, boat untouched 96/100 — the v0 sim is not yet a policy meter; visual matching is the lever) → owner redirect executed mid-ride (rung arms killed, 3 replacement policy arms launched 23:44Z). Instrument: rollout_sim out-json/hold/method flags, reads + charts + 6 oracles.
