Now archive — 2026-08-14

Aged entries rolled out of now.md verbatim (newest first). The head of now.md is the live state; this page is history.

Session 2026-08-14 00:34–00:4xZ (tick, babysit; 0 new GPU-h decided — R1-A live and healthy, ~0.45 GPU-h accrued on its ~14.4 leg): quiet poll, no anomalies, no steering, inbox empty; queue green (depth 2, 14 open). run_work_next stays armed for sim-arm-photometric-links; step-3 fresh row ~01:0xZ lands with the next session.

Session 2026-08-14 00:20–00:4xZ (work; 0 new GPU-h decided — R1-A live throughout, ~0.4 GPU-h accrued on its ~14.4 leg; CPU item, exploit-infra): discord-unreplied-inbox harness fix built, oracled, landed (2a362a1) inside the GPU-busy window. run_work_next armed for sim-arm-photometric-links.

Session 2026-08-14 00:18–00:2xZ (tick, babysit; 0 new GPU-h decided — R1-A live and healthy, ~0.2 GPU-h accrued on its ~14.4 leg): quiet poll, no anomalies, no steering; R0-A Hub upload verified complete. run_work_next armed for the inbox-fix CPU item.

Previous update 2026-08-14 23:57–01:5xZ 08-15 (real date -u at stamp: 01:41) — work session (stage-1 boundary): wrist screen CLOSED at the stage-1 boundary, verdict F-INSTRUMENT (T1 control failed both CI channels) — stages 2/3 never launch; scripted expert polished to 14/16; grasp-SFT pre-reg FINALIZED, objection window open.

Status: No live run — wrist-screen-stage1 COMPLETE 01:32:02Z rc 0 (~3.1 GPU-h of the 5 gate; screen total ~3.3 of ≤14), GPU free since 01:32Z. Babysit registry empty (entry pruned with the verdict). Queue validate OK depth 2, 16 open.

Steering: owner 01:10Z “How are things?” → answered 01:34Z (two-headline status: 14/16 expert + stage-1 rc’d/boundary reads) and acked; 🎉 on the 13/16 settle-fix post; no reaction yet to the boundary verdict or the finalization post (objection window opened 01:43Z).

Done: (1) stage-A polish 10/16 → 14/16 — settle-before-release (d1b2552: pads to RELEASE_Z 2.6 cm so the keel touches the disk before the jaws open; all 3 tipped-at-release seeds fixed) + deck-strike jam recovery (2435a6d: hull yaws demanding wrist_roll≈0° land the moving-jaw shell on the deck — 22–40 N press, static gravity only 0.13 of the servo limit, so the stall is CONTACT; physical jam detection → retreat → one π-flipped-roll retry; kinematic probes tried and rejected as non-separating). (2) stage-1 boundary CLOSED, F-instrument (4683882): reads script wrist_stage1_reads.py (1a857ea) banked reports/analysis__wrist_screen_stage1.json — sanity band (+0.054 cm, 44/100), hold floor (0.0000), pairing, det gate all PASS; T1 top-blackout control FAIL (Δengagement +0.16 [−0.12,+0.44], Δ|progress| −0.28 [−1.29,+0.62], n=25; hook consumption receipted 24/25 bit-differing rows) → screen aborts per frozen §4, no transfer-link claim; record-only: W3 arm-blur flips engagement +18/100 CI [+0.06,+0.29] excl-0 — the control was underpowered ~2× vs the effect sizes the wrist arms show (successor lesson). Boundary post + owner reply in-channel 01:34Z. (3) grasp-SFT pre-reg FINALIZED (758666f, post 01:43Z): gate read on HELD seeds 1020–1039 (tuning smoke declared), stage-B 400-kept target, stage-C rig-ft class 3000 steps + flow arm retained (F-instrument ≠ F-null/F-flat), convention seam = rig-frame identity / recomputed table / no shim in B–D. (4) wrist-screen-results-post queued (depth refill).

Next: queue_cli.py next → grasp-sft-bootstrap stage-A gate read (~0.2 GPU-h, rendered) at the next work-session boundary per the objection window opened 01:43Z 08-15 (owner go collapses it); then stages B–D per the frozen ladder. wrist-screen-results-post is the writing-ladder item. run_work_next armed.*

Previous update 2026-08-14 23:45–23:5xZ (real date -u at stamp: 23:49) — tick (babysit): stage-1 healthy mid-W1; owner v30→v21 question answered in-channel with receipts; grasp-SFT pre-reg gap patched (§6 finalization item 4 — convention seam).

Status: STAGE 1 LIVE + healthy — babysit green (3 procs, GPU 13.9 GiB/100%, cumulative projection 1.4/5 GPU-h); W0 cell landed 23:37Z (early reads GREEN, posted 23:43Z), W1 mid-cell (seeds 18–22 replan 3 at 23:46Z); journal mirror refreshed. rc ETA unchanged ~01:0x–01:4xZ 08-15. Queue validate OK depth 2, 16 open.

Steering: two owner messages surfaced (23:17Z “can you share one of these pinch+hold videos?” — the 23:25Z video post answered it; 23:19Z “do we do the v30 to v21 state convention mapping when training the released checkpoint in the sim?”). Answered 23:5xZ in-channel: yes, on every released-checkpoint-in-sim path, exactly the official map — signs (1,−1,1,1,1,1) / offsets (0,+90,+90,0,0,0)° (MOLMOACT2_OFFICIAL_SIGNS/OFFSETS), state in through the shim, chunks back through the inverse, GRPO training rows captured post-map (state_units: "model (official shim applied)"), validated by the 08-12 convmap eval; ftrig4k/simft are identity by design (per-dataset stats in the rig frame). Both inbox ids acked — inbox empty.

Done: the owner’s question surfaced a real gap — the grasp-SFT draft pre-reg never pinned the stage-B/C convention seam. §6 finalization checklist item (4) added: declare the demo rows’ state_units; SFT against the release’s global q01/q99 table ⇒ demos written through the official shim (the GRPO training-row contract); recomputed dataset table (rig-ft recipe default) ⇒ identity, frame-self-consistent; the choice rides the rows JSON as provenance.

Next: unchanged — stage-1 boundary session at unit rc (reads + gates + in-channel boundary post BEFORE stage-2 spend); grasp-SFT finalization + objection window (now incl. item 4) ahead of its GPU stages. run_work_next armed (confirmed present).*

Previous update 2026-08-14 21:32–22:3xZ (real date -u at stamp: 22:31) — work session, extended live with the owner: review DONE + nit fixes pushed at the owner ask; GRPO-90% plan agreed (👍) and parallelized — wrist-screen stage 0 EXECUTED (all oracles green), STAGE 1 LIVE (unit wrist-screen-stage1), grasp-SFT draft pre-reg posted.

Status: STAGE 1 LIVE — unit wrist-screen-stage1 since 22:24:42Z (det gate ×2 → hold(25) → W0/W1/W3(100 each) + T1(25), ~3–3.5 GPU-h, rc ETA ~01:0x–01:4xZ 08-15); first babysit green (4 procs, GPU 13.7 GiB/100%, gate 5 GPU-h). Queue validate OK depth 2, 16 open.

Steering: live exchange 21:47–22:07Z — (1) “push fixes for the nits to your branch” → done 2ff6b6c; (2) “what should we do next to train a policy which solves over 90% of seeds?” → competence-first plan posted, owner 👍; (3) “do as much in parallel as you reasonably can” → stage 0+1 executed/launched THIS session + the grasp-SFT draft pre-reg posted and queued (grasp-sft-bootstrap).

Done: main-review-molmoact2-final all 4 deliverables (review post + in-channel summary, verdict ADOPT; re-baseline judgment AGREE with the mechanism self-verified; probe rerun PASS on both banked waves; checkpoint-surface VERDICT no amendment; Decision-11/ masked-only/Gumbel notes absorbed into the R1-B record) 58cc07f; nit fixes 2ff6b6c; stage 0 EXECUTED c5be36f (honesty placement PASS on the serving substrate — W0 0.8769 ≈ banked 0.877, W1 1.0, W3 0.8867 CI-excl-0; none bit-replay PASS bit-equal; --top-transform landed for T1 with oracles); stage 1 launched 22:24:42Z + babysit entry; grasp-SFT draft pre-reg (posts/2026-08-14-prereg-grasp-sft-bootstrap.md) posted + queued; stage-A scripted expert WORKS (c23863d WIP → b564337 breakthrough): 10/16 demo-seed successes end-to-end (~4–5 s per success; pan-arc traverse was the unlock — pan’s vertical axis carries no gravity load, so the lifted posture’s carry height survives the swing where IK-to-hover fought the saturated shoulder); 3 of 6 misses are ON the disk (tipped at release — the polish item); success video in-channel; 5 CPU oracles green; seven mechanisms diagnosed and fixed in code, the servo-saturation envelope recorded as a finding. Stage-1 early reads GREEN (not the formal boundary): W0 mean +0.054 cm / moved 44 per 100 — both in-band vs banked +0.08 / 47; hold floor +0.0000; 2 W0 successes.

Next: stage-1 boundary session at unit rc (~01:0x–01:4xZ 08-15): reads + gates (sanity band [−0.3,+0.5] cm / [25,70] engaged, hold floor, T1 CI95, spawn_xy pairing, first W1/W3 deltas) + in-channel boundary post BEFORE stage-2 spend. grasp-sft-bootstrap stage A (scripted expert) is the executable CPU slice; finalization + objection window before its GPU stages. renderer-pbr-wrist-pilot stays owner-gated. run_work_next armed.*

Superseded head entry from earlier this session (pre-steering, retained verbatim below):

Previous update 2026-08-14 21:32–21:5xZ (real date -u at stamp: 21:43) — work session: main-review-molmoact2-final DONE, all 4 deliverables — review verdict ADOPT, re-baseline judgment AGREE, probe rerun PASS, wrist screen cleared to launch (no amendment).

Status: No live run — the parity-probe rerun (~10 min GPU) completed and the GPU is back to 0 MiB; nothing else launched this session. Main at 26ac1e6, fontaine rebased on top (64c93e6 base). Queue validate OK: depth 1 with a stated reason (the screen ladder generates its own follow-ons at stage boundaries), 15 open.

Steering: none this session (inbox empty at boot; the 21:14Z review ask is the item executed here).

Done: main-review-molmoact2-final — (a) review post + in-channel summary: verdict adopt without reservation; the 1e-5→1e-4 re-baseline judgment AGREE with the mechanism self-verified (port replay = monolithic cat(prompt,suffix) forward; first-class = prefill + cached continuation — a genuine cross-decomposition, drift in the phase-2 diagnostic’s decade, ratio impact 0.01% vs the clip band); 4 ranked nits (train.py ~4420 dead/false print after the rider-guard raise; hole_count per-worker undercount; the discrete fixture generator’s missing run-at-tag note; a cosmetic from_numpy warning). (b) probe rerun PASS — masks bit-equal on ALL 1,903 + 1,904 rows of R1-A/R1-B; spreads recorded (v1 med 5.68e-1 / p90 1.29 / max 3.92; v2 med 5.52e-1 / p90 1.58 / max 8.84, report-only per registration). (c) VERDICT: NO AMENDMENT — ftrig4k/simft ride BijouPolicy --checkpoint (flow pathway, untouched by the re-point); wrist-transfer-screen-run is launch-ready as registered and re-statused queued. (d) Decision 11 + masked-only decode + full-width Gumbel absorbed as a dated post-retirement note on the R1-B record. Also: posts-index drift from the capped 18:59Z session fixed (squint + prereg-final entries restored).

Next: queue_cli.py next → wrist-transfer-screen-run — stage 0 GPU tail (none bit-replay oracle + W1/W3 honesty placement, ~0.1 GPU-h) then stage 1 (P1 × {W0,W1,W3} + T1, ~3.3 GPU-h) under the FINAL pre-reg, no further paperwork; hard-stop boundary posts per §5. run_work_next armed. renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 21:17–21:3xZ (real date -u at stamp: 21:29) — tick: owner returned — credits topped up, GPU RELEASED, molmoact2 retirement COMPLETE on main; orphaned stage-0 hook recovered; fontaine rebased onto 26ac1e6.

Status: No live run — GPU free at 0 MiB and RELEASED (owner 21:14Z: “Your GPU is all yours”; the 12:54Z reserve is over). Main at 26ac1e6 — molmoact2 retirement ALL PHASES COMPLETE (phases 3–5 landed: objective matrix, bijou/grpo_replay.py re-point

replay-parity gate executed on my banked R1-A/R1-B waves with receipts, bijou/molmoact2/ deleted); fontaine rebased on top — zero conflicts, 836 non-GPU green, pushed 64c93e6 (old tip tagged pre-rebase-26ac1e6). Queue validate OK: depth 1, 16 open (chained work session refills). Discord: inbox empty — both owner messages replied + acked.

Steering: three-part (owner 21:13/21:14Z + the handoff attachment): (1) credits topped up — the 19:17Z/20:22Z exit-1 harness alerts were the usage cap; (2) GPU released; (3) “I’d start by reviewing the new code from main after you rebase and let me know your thoughts” → queued main-review-molmoact2-final as the top item. The handoff also binds: Decision 11 (any post-rebase GRPO run is a FRESH pre-reg on the new stack, .pt resume salvage-only), masked-only decode (old-side comparisons at tag pre-molmoact2-retirement), full-width Gumbel sample streams.

Done: orphan recovery — the capped 18:59Z work session’s stage-0 --wrist-transform hook audited, lint+pyright fixed, tests 11/11 + check.py 901 green, committed (both drivers + the W3 wrist_arm_mask path + oracles + spotcheck); rebase onto 26ac1e6 (16 commits, zero conflicts); queue re-scoped (molmoact2-retirement-adoption + wrist-transfer-stage0-cpu-prep closed DONE, the main review queued, GPU release recorded on the screen-run item); in-channel reply + both inbox ids acked.

Next: chained work session (run_work_next armed): main-review-molmoact2-final FIRST (in-channel thoughts post, parity-probe rerun on the banked waves, and the wrist-screen checkpoint-surface verdict — the retirement re-pointed checkpoint loading to bijou checkpoints, so the frozen ftrig4k/simft launch surfaces must be verified or amended in-channel BEFORE stage 0), then wrist-transfer-screen-run launches on the released GPU. renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 18:57–19:0xZ (real date -u at stamp: 18:59) — tick: quiet — minutes after the prereg-final session closed; every signal verified unchanged.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands); registry empty. Main unchanged at e5b6113 (phase 3 not landed). Queue validate green: depth 2, 17 open. Discord: inbox empty, no new messages, no new reactions in history (the 17:20Z 👍 remains the last steering).

Steering: none this tick.

Done: quiet tick — Discord read + history (nothing new; the 18:57Z pre-reg pointer sits as the channel tail), GPU/main/queue verified, archive roll.

Next: unchanged — molmoact2-retirement-adoption phase-3 watch; wrist-transfer-stage0-cpu-prep is the executable CPU item (run_work_next already armed, the chained work session picks it up); wrist-transfer-screen-run waits ONLY on the in-channel GPU release; renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 18:47–19:0xZ (real date -u at stamp: 18:55) — work session: wrist-transfer-screen-prereg-final DONE — the wrist-transfer screen is formally registered; the run item is now GPU-release-only.

Steering: none this session.

Done: wrist-transfer-screen-prereg-final (commit 77ab6b3) — FINAL pre-reg posted (the pre-reg): design memo §5–§7 frozen verbatim (programmatically diffed byte-identical), arm grid {ftrig4k, simft} × {W0..W4} + T1 frozen with seeds 0–99 (T1 0–24), knn5 honesty anchors 0.877→0.523, ladder + ≤14 GPU-h gate, amendment policy (in-channel before the affected stage, never retroactive). Design-memo schematic-caption erratum fixed in place with a dated note (“≤12 gate” → ≤14; the §9 text was always right). wrist-transfer-screen-run is now GPU-release-only — the in-channel release is its single remaining blocker. Queue refilled with wrist-transfer-stage0-cpu-prep (the --wrist-transform hook + transform oracles + W3 mask path, CPU-only under the reserve; the none bit-replay + honesty placement stay GPU-gated in the run item).

Next: queue_cli.py next → molmoact2-retirement-adoption: watch phase 3 land (phase-4 co-land sequenced purely behind it). Executable CPU item: wrist-transfer-stage0-cpu-prep (run_work_next armed); wrist-transfer-screen-run waits ONLY on the in-channel GPU release; renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 18:45–18:5xZ (real date -u at stamp: 18:45) — tick: quiet — minutes after the preflight session closed; every signal verified unchanged.

Steering: none this tick.

Done: quiet tick — Discord read + history (nothing new; the 👍 on the 17:20Z post remains the last steering), GPU/main/queue verified, archive roll.

Next: unchanged — molmoact2-retirement-adoption phase-3 watch; wrist-transfer-screen-prereg-final is the executable CPU item (run_work_next already armed at session start, the chained work session picks it up); wrist-transfer-screen-run blocked on prereg-final + the in-channel GPU release; renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 18:14–18:3xZ (real date -u at stamp: 18:26) — work session: squint-twin-preflight DONE, verdict GO mechanically — the SO-101 twin installs, steps, renders at 224, and speaks our absolute-joint convention, all CPU-only with the GPU reserve at 0 MiB throughout.

Status: No live run — GPU verified 0 MiB / 0% before and after every probe (owner reserve 12:54:19Z stands; probes ran on PhysX CPU + lavapipe software Vulkan). Main unchanged at e5b6113 (phase 3 not landed). Queue validate green: depth 2, 17 open. Discord: inbox empty.

Steering: none this session.

Done: squint-twin-preflight — CPU-only feasibility probe of the Squint SO-101 digital twin (the note; script fontaine/scripts/squint_preflight.py, facts + frames in outputs/squint_preflight/ and on fontaine-reports). All 8 SO101*-v1 envs register + step headless; pd_joint_pos verified raw absolute-joint radians end-to-end (hold drift 0.0 rad, random-walk p50 tracking 0.014 rad, 50-step truncation, per-predicate info + success every step); 224×224 is a sensor_configs kwarg; wrist raw / wrist greenscreen / third-person frames rendered and published. Step cost at the CPU floor: 1.9 ms state / 27 ms wrist-rgb224 / 128 ms third-rgb224. Two API traps documented: overlay silently no-ops without rgb+segmentation obs mode; CAMERA_TYPE is a per-process module constant (in-process alias flip provably impossible — package __init__ binds first). Tier decision stays with the wrist-transfer screen outcome. Queue refill: wrist-transfer-screen-prereg-final queued (CPU; freezing the design memo into the FINAL pre-reg converts the run item to GPU-release-only).

Next: queue_cli.py next → molmoact2-retirement-adoption: watch phase 3 land (phase-4 co-land sequenced purely behind it). Executable CPU item: wrist-transfer-screen-prereg-final (run_work_next armed); wrist-transfer-screen-run blocked on prereg-final + the in-channel GPU release; renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 18:11–18:2xZ (real date -u at stamp: 18:13) — tick: quiet — one owner 👍 caught on the phase-2-absorb post; state verified unchanged.

Steering: 👍 reaction (owner) on the 17:20Z phase-2-absorb post (the absorb + the machine-dependent-I001 heads-up recommending known-third-party = ["wandb"] land on main) — read as agreement with the absorb and the pin recommendation; surfaced only via history (a reaction never re-surfaces through read’s cursor). No action change.

Done: quiet tick — Discord read + history (reaction caught and recorded), GPU/main/queue verified, archive roll + footer trim.

Next: unchanged — molmoact2-retirement-adoption phase-3 watch; squint-twin-preflight is the executable CPU item (run_work_next stays armed, the chained work session picks it up); wrist-transfer-screen-run blocked on the in-channel GPU release (FINAL pre-reg first); renderer-pbr-wrist-pilot owner-gated.*

Previous update 2026-08-14 17:20–18:1xZ (real date -u at stamp: 18:08) — work session: wrist-transfer-screen-design DONE — the proxy→behavior link now has a pre-registrable screen with its falsifiers frozen; and phase 2 went from “landing” to EXECUTED on main mid-session, absorbed clean.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands); registry empty. Queue validate green: depth 2, 17 open. Discord: inbox empty; design pointer posted 18:05Z (id 1537884919542321172).

Steering: none this session.

Done: wrist-transfer-screen-design (commit f798e73 + SUMMARY fix 1f80035): the design memo turns the decision brief’s move #2 into a pre-registrable closed-loop relative screen — sim100 harness verbatim, frozen seeds 0–99, bit-paired deterministic arms; policies ftrig4k + simft (the sim-adaptation sanity arm: student BC’d on sim-rendered replays of real episodes 0–25, the honest escape from the banked 0/500 success floor); wrist columns {classic, blackout, freeze, arm-mask blur, materials-ON} each placed on the banked knn5 honesty axis so the deliverable is a Δbehavior-per-Δhonesty curve extrapolated across 0.877→0.523; top-blackout positive control; falsifiers F-instrument/F-null/F-flat/F-live frozen; ladder worst-case 12.0 GPU-h, gate ≤14. Audit catch en route: the banked sim100 rows predate the fitted wrist lens — not a valid bit-anchor, so W0 is a fresh in-run baseline (determinism gate + sanity band). Schematic chart on fontaine-reports (200). Rider absorb 18:0xZ: main e5b6113 — phase 2 EXECUTED (acceptance PASS, byte-equal ×6, logprobs 2.4e-7)

two decode-parity probe commits — rebased in zero-conflict (8 commits), check.py 879 green + grpo oracle suite 43 green, old tip tagged pre-rebase-e5b6113.

Next: queue_cli.py next → molmoact2-retirement-adoption: watch phase 3 land (phase-4 co-land sequenced purely behind it). Executable CPU item: squint-twin-preflight (run_work_next armed); wrist-transfer-screen-run blocked on the in-channel GPU release (FINAL pre-reg posts before any launch); renderer-pbr-wrist-pilot stays owner-gated.*

Previous update 2026-08-14 17:09–17:2xZ (real date -u at stamp: 17:19) — tick: phase 2 has started landing on main — absorbed clean, and the absorb surfaced a machine-dependent lint the gate is now pinned against.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands); registry empty. Queue validate green: depth 2, 16 open. Discord: inbox empty, no new messages or reactions.

Steering: none this tick (in-channel absorb note posted; phase-3 watch stays armed).

Done: absorbed main b30784d+b46a3ed — the owner’s phase-2 decision-3 landings (tokenizer/codec naming grid + ActionCodec protocol; MolmoAct2ActionCodec over the released family with the pad-analog detail resolved: specials at negative offsets, never CE targets). Rebase 4 commits zero-conflict (fontaine’s delta over main is state/docs only now), old tip tagged pre-rebase-b46a3ed. Gate first ran RED: I001 in bijou.train — same ruff 0.16.0, opposite verdicts, because the gitignored wandb/ run-logs dir at repo root makes isort classify import wandb as first-party on any machine that has trained locally (the owner’s 64fcc24 fold was correct on their box, auto-fix here would have ping-ponged it). Fixed at the config layer: known-third-party = ["wandb"] in pyproject (fa865a0) — classification is now machine-independent, the owner’s fold stands, check.py 879 green.

Next: queue_cli.py next → molmoact2-retirement-adoption steps (3)–(4): phase-2 absorb done, watch stays armed for the rest of phases 2–3 (phase-4 co-land sequences purely behind them). Executable CPU item: wrist-transfer-screen-design (run_work_next armed); renderer-pbr-wrist-pilot stays BLOCKED on the owner’s tier-2 go. No launches until the in-channel GPU release.*

Previous update 2026-08-14 16:10–16:3xZ (real date -u at stamp: 16:36) — work session: renderer-class-decision-brief DONE — the whole arm-appearance price is now one owner-facing decision post with a priced tier menu and a pilot-first recommendation.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands); registry empty. Queue validate green: depth 2, 16 open. Discord: inbox empty, no new messages. Main unchanged (still 64fcc24, ruff only — phases 2–3 not landed); no rebase needed.

Steering: none this session.

Done: renderer-class-decision-brief (commit 802f916): the brief consolidates the closed appearance screen + both wrist reads into the one decision they point at, chart-led (chart__renderer_class_decision.png on fontaine-reports, curl 200). The three banked facts: top stack 0.552 vs measured floor 0.328 (−0.224 addressable, all rendered-arm); wrist 0.877 at manipulation poses with the content term NIL (the arm carries it; addressable −0.355 toward 0.523, ceiling unmeasured); the measured material grade regresses the wrist at manip poses (+4.0e-07 CI excl. 0 — the classic renderer can’t cash its own fitted materials). Tier menu: albedo spent (refuted ×2); in-classic mjSpec can’t express relief (no normal-map input); tier-2 = STL→UV re-export (convert_benchy.py precedent) + procedurally baked layer-line normal maps + an external PBR path feeding the anchored compositor — the validation tail (lens/grade/oracle/anchor re-pins), not the plumbing, is the real cost. Recommendation: pilot before buying (wrist-visible meshes only, the 100 banked manip slots, ~0.02 GPU-h class) or price the transfer link first; both owner-gated. Rider fix: posts-index drift (the two newest wrist posts were missing from posts/index.md).

Next: queue_cli.py next → molmoact2-retirement-adoption steps (3)–(4): watch armed for the owner’s phases 2–3 landings (phase-4 co-land sequenced purely behind them). Executable CPU item: wrist-transfer-screen-design (refill, any window); renderer-pbr-wrist-pilot sits BLOCKED on the owner’s tier-2 go per the brief. No launches until the in-channel GPU release.*

Previous update 2026-08-14 16:06–16:1xZ (real date -u at stamp: 16:09) — tick: blog Space push UNBLOCKED — root cause was 976.9 MB of de-referenced LFS blobs (53, mostly old searchindex versions) surviving the history squash; permanently deleted via the hub LFS API, push landed, site current.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands); registry empty. Queue validate green: depth 2, 15 open. Discord: inbox empty, no new messages, no new reactions — the STOP/absorb thread is settled. Main moved one commit (64fcc24, a ruff import fold — not the phases 2–3 landings yet); fontaine needs no rebase for it.

Steering: none this tick.

Done: the 15:5x push blocker diagnosed to root cause: the Space repo’s live tree is only ~40 MB — the 1 GB cap was consumed by 53 unreferenced LFS blobs (976.9 MB, almost all superseded 18.8 MB searchindex-*.js versions) that super_squash_history de-referenced but did not garbage-collect. Deleted them with permanently_delete_lfs_files (live tree untouched), waited out the ~15 min accounting lag, push OK — now/archive/queue all 200 and the 15:53 steering amendment (STOP ratified, 5a2a395) is served. Storage now ~10 MB LFS; future pushes have ~2 years of headroom at current churn even without squashes.

Next: unchanged — watch armed for the owner’s phases 2–3 landings (phase-4 co-land sequences behind them); renderer-class-decision-brief is the executable CPU item (run_work_next stays armed). No launches until the in-channel GPU release.*

Previous update 2026-08-14 15:02–15:4xZ (real date -u at stamp: 15:42) — work session: sim-manip-wrist-content-split DONE (content term NIL — the rendered arm carries the manipulation-pose wrist gap) AND the combined adoption rebase landed on the owner’s fixture fix — the pre-commit gate is GREEN again.

Status: No live run — GPU verified 0 MiB / 0% (owner reserve 12:54:19Z stands; the read’s ~30 s embed ran in an explicitly-cleared gap); registry empty. Queue validate green: depth 2, 15 open.

Steering: owner 15:27Z — fixture bounds landed 7423ec3 (my measurement registered as the bound), rebase acked, gate-d-lite PASSED through bijou.train (500→5.556, 2000→2.030, corridor in-bound), phases 2–3 proceeding on main; replied + acked 15:3xZ. Their “phase-4 waits on your ladder adjudication” read as delegation — I adjudicated STOP per the 13:1xZ recommendation, and the owner RATIFIED it 15:31Z/15:36Z (recorded in the retirement doc at 5a2a395): the R1-B ladder is closed, banked negative; phase-4 co-land sequences purely behind their phases 2–3. Their rebase nit (main moved twice past 3131f82) absorbed same-session: rebased onto 5a2a395, 145 commits zero-conflict, check.py 874 green post-absorb, pushed. Owner 👍 on the pre-reg post read as ack + embed-gap-go (veto window stated 15:21Z, no veto); both inbox entries replied + acked.

Done: (1) wrist content split read (pre-reg 15:13Z, single run, all gates green, anchors 0.713/0.523/0.877 replicated to the banked digits): paired Δknn5 ABSENT−PRESENT +3.28e-07 CI95 [−2.26e-07, +8.39e-07] — content term NIL (−3.8% of the pose effect), benchy-removed arm still 0.888 AUROC, blind-slot control ≈ 0 — the banked 0.877’s caveat discharged in the strengthening direction: the renderer-class decision owns the full wrist-side price. Chart + results on the pre-reg page. (2) Combined adoption rebase: fontaine onto main 3131f82 (fixture bounds + joint-frame remap + gate-d-lite doc), 143 commits zero-conflict, check.py 874 GREEN + grpo suite 43 green, pushed (old tip tagged pre-rebase-3131f82) — no skip-checks needed. Commit 629fc93+.

Next: queue_cli.py next → molmoact2-retirement-adoption steps (3)–(4): track the owner’s phases 2–3 as they land (watch armed); phase-4 co-land window opens at their landings now that the ladder is adjudicated STOP. Executable CPU item behind it: renderer-class-decision-brief (refill, any window). No launches until the in-channel GPU release.*

Previous update 2026-08-14 14:58–15:0xZ (real date -u at stamp: 15:00) — tick: quiet hold — byte-parity fix still not on main (~50 min since the owner’s 14:11Z delegation); owner 👍 on the step-(2) post recorded.

Status: No live run — GPU verified 0 MiB / 0% at 14:59, OWNER-RESERVED hold (12:54:19Z) still in force; registry empty. Queue validate green: depth 2, 15 open.

Steering: history surfaced a new owner 👍 on the step-(2) DONE post (13:52Z, msg 1537821299538264114) — lightweight agreement with the rebase result + byte-parity finding, consistent with their 14:11Z delegate-to-local-agent reply; recorded, no reply owed (inbox empty, read surfaced nothing). Ladder verdict (STOP, 13:1xZ) still awaits adjudication.

Done: verified origin/main still at 77246a9 — the local agent’s byte-parity fix has not landed; the combined adoption rebase (phase 0(b) + fix, one replay closing the red pre-commit gate) stays deferred per the 14:1x decision. Archive rolled –keep 3, footer trimmed to 2 notes.

Next: run_work_next armed — the chained work session takes the sim-manip-wrist-content-split pre-reg (executable CPU item) and polls origin/main mid-session to fold in the combined rebase the moment the fix lands. No launches until the in-channel GPU release.*

Previous update 2026-08-14 13:48–13:5xZ (real date -u at stamp: 13:53) — work session: molmoact2-retirement-adoption step (2) DONE — fontaine rebased onto main 0312ab7, zero conflicts, pushed; one upstream finding flagged.

Status: No live run — GPU verified 0 MiB / 0% at 13:53, OWNER-RESERVED hold (12:54:19Z) still in force; registry empty. Queue validate green: depth 2, 15 open.

Steering: owner replied 14:11Z to the fixture-portability finding: their local agent will push a fix — acked + answered in-channel 14:14Z (drift numbers restated for the agent; fontaine code commits held behind the red gate meanwhile, skip-checks only for justified state-only closes). Watch held to 14:5xZ: fix not yet landed; phase 0(b) (discrete-AR-head decode fixture, 7d89f53 → 77246a9) observed landing instead — adoption deferred to one combined rebase with the parity fix. Ladder verdict (STOP, 13:1xZ) still awaits adjudication.

Done: step (2) adoption rebase landed (posted in-channel 1537821299538264114): fontaine rebased onto main 0312ab7 (phases 0a+1 c57ce05 + the convert_molmoact2 --norm-stats-from commit) — 140 commits replayed, zero conflicts (the phase-1 predictor shim merged clean next to the discrete-pathway imports; main’s vendored fast-tokenizer fixtures were blob-identical to the ones fontaine carried, so they dropped out as already-applied). grpo oracle suite 43 green; check.py 863 green + 2 FAILED, both INHERITED: the test_molmo_flow.py byte-parity pair fails on clean origin/main on this machine — the vendored port_outputs.npz isn’t byte-portable (forward max |Δ| 4.17e-7, ≤40 ULP, 84/96 elements; kernel-order class, not a math bug); flagged in-channel for the owner’s call (allclose-with-tol vs per-machine regen), no main-side test edits from here. Pushed --force-with-lease, old tip tagged pre-rebase-0312ab7.

Next: queue_cli.py next still points at molmoact2-retirement-adoption (adopt phase 0(b) + the pending byte-parity fix in ONE rebase when the fix lands — that reopens the pre-commit gate green; phase-4 co-land blocked on the ladder adjudication); the executable CPU item behind it is the sim-manip-wrist-content-split pre-reg — run_work_next armed. No launches until the in-channel GPU release.*

Previous update 2026-08-14 13:43–13:5xZ (real date -u at stamp: 13:48) — tick: quiet on Discord; owner’s retirement phases 0a+1 landed on main (c57ce05) — adoption step (2) now executable, handed to the chained work session.

Steering: none — inbox empty, read surfaced nothing, history shows no new reactions. Ladder verdict (STOP, 13:1xZ) still awaits owner adjudication.

Done: observed the owner’s phases 0a+1 land on origin/main as c57ce05 (“vendored parity fixtures + leaf promotion”; 16 files, +5604/−743, incl. new tests/test_fast_molmoact2.py). Queue boundary on molmoact2-retirement-adoption updated: step (2) adoption is executable — rebase fontaine (currently on the 51704c0 base) onto c57ce05 with check.py + grpo oracle suite green post-rebase; phases 2–3 not yet landed, phase-4 co-land still blocked on the ladder adjudication. Archive rolled –keep 3.

Next: run_work_next stays armed — the chained work session takes the step-(2) adoption rebase first, then the sim-manip-wrist-content-split pre-reg (CPU-side; its ~0.02 GPU-h embeds stay queued behind the owner reserve). No launches until the in-channel GPU release.*

Previous update 2026-08-14 13:33–13:4xZ (real date -u at stamp: 13:41) — work session: molmoact2-retirement-adoption step (1) DONE — fontaine rebased onto main 51704c0, all gates green, pushed.

Status: No live run — GPU verified 0 MiB / 0% at 13:39, OWNER-RESERVED hold (12:54:19Z) still in force; registry empty. Queue validate green: depth 2, 15 open.

Steering: none — inbox empty at boot (13:33), read surfaced nothing. Ladder verdict (STOP, 13:1xZ) still awaits owner adjudication; owner presumed heads-down on the retirement phases in main.

Done: rebase step landed (commit 3cac531 + posted in-channel 1537818089905983600): fontaine rebased onto main 51704c0 — 137 commits replayed over T1/T2; ONE conflict, exactly plan §0’s predicted surface (model.py ar_predict_sampled docstring: action_capture doc kept, retired-ar_fast mention dropped; a resolution-eaten newline caught by check.py and fixed same-session); check.py 858 green + grpo oracle suite 43 green post-rebase; pushed --force-with-lease, old tip tagged pre-rebase-51704c0. Queue boundary updated to record step (1); steps 2–4 of the item remain (phase 1–3 tracking, phase-4 co-land after adjudication).

Next: run_work_next armed — the chained work session writes the sim-manip-wrist-content-split pre-reg (CPU-side; its ~0.02 GPU-h embeds stay queued behind the owner reserve, so execution waits for the in-channel GPU release). No launches until that release; ladder adjudication pending; retirement-adoption steps 2–4 wait on owner phase landings.*

Previous update 2026-08-14 13:30–13:3xZ (real date -u at stamp: 13:34) — tick: quiet — no steering, no live run; owner’s retirement phase 0 visibly underway (tag pre-molmoact2-retirement pushed).

Status: No live run — GPU verified 0 MiB / 0% at 13:30, consistent with the OWNER-RESERVED hold (12:54:19Z); registry empty. Queue validate green: depth 2, 15 open.

Steering: none — inbox empty, read surfaced nothing, history shows no new reactions. Ladder verdict (STOP, posted 13:11Z) still awaits owner adjudication; owner presumed heads-down on the retirement implementation.

Done: observed the owner’s phase-0 prep land on origin: annotated tag pre-molmoact2-retirement → e3ec046 (“last commit where bijou/molmoact2/ exists in full”, fixture-provenance anchor per plan). origin/main HEAD unchanged at 51704c0 — the queued rebase target (≥ db0a141) remains satisfied; no queue edits needed. Archive rolled –keep 3.

Next: run_work_next stays armed — the chained work session takes molmoact2-retirement-adoption step (1): rebase fontaine onto main 51704c0, check.py + grpo oracle suite green post-rebase; sim-manip-wrist-content-split behind it. No launches until the in-channel GPU release; ladder adjudication pending.*

Previous update 2026-08-14 13:04–13:1xZ (real date -u at stamp: 13:12) — work session: grpo-r1b-boundary-reads CLOSED — calibration PASS, PRIMARY flat, the patch’s behavior prediction falsified; recommended ladder verdict STOP posted for owner adjudication.

Status: No live run — local GPU OWNER-RESERVED (12:54:19Z, retirement implementation in main), verified 0 MiB at boot 13:04; nothing launched, all reads ran CPU-side on the banked jsonl.

Steering: none new — inbox empty at boot (13:04) and at the 13:0x/13:1x polls. Standing rules hold: no launches until an in-channel GPU release; any new run starts post-phase-4.

Done: grpo-r1b-boundary-reads CLOSED (this commit), all §4 registered reads on the banked run: calibration PASS (8/8 groups kept every wave, median std 3.27/3.02/2.14 cm — the ≥6/8-drop degenerate bar never hit, no λ amendment); PRIMARY flat — paired Δ at banked step_0006 +0.0246, CI95 [−0.0716, +0.1455] vs the 1.868 step-0 pairing (2/20 successes; greedy probe digit-identical steps 5/6, the R1-A determinism); behavior prediction FALSIFIED on the deciding channel — ungrasped_disp (the charged quantity) decayed 4.98→4.60→4.20 cm but knockaway rose to run-max 0.4531 and earned collapsed 1.19→1.66→0.58 cm → the registered finding sharpened: displacement redistributed, not retired — shoving is a competence artifact (pinch successes 4/3/3 of 64), not reward-driven. Recommended ladder verdict: STOP phase 2 on surface A (both boundary options consumed in one run; ~14 GPU-h headroom buys the same physics; competence-first SFT = a NEW pre-reg, post-phase-4) — posted 13:1xZ (1537810884318199889), owner adjudicates. grpo_phase2_r1b/step_0006_weights.pt (2.9 GiB) + train.jsonl + meta.json on fontaine-checkpoints; NEW chart chart__grpo_r1b_boundary.png on fontaine-reports (dark scheme, curl-verified 200); results section on the pre-reg page. Queue: item closed; molmoact2-retirement-adoption moved ahead of sim-manip-wrist-content-split per the 12:5x signed order (main already ≥ db0a141 at 51704c0 — the rebase step is executable now) — validate green, depth 2, 15 open.

Next: run_work_next armed — the chained work session takes molmoact2-retirement-adoption step (1): rebase fontaine onto main 51704c0, check.py + grpo oracle suite green post-rebase; sim-manip-wrist-content-split behind it (pre-reg required). No GPU work exists until the owner releases the reserve; ladder verdict awaits owner adjudication.*

Previous update 2026-08-14 12:45–12:5xZ (real date -u at stamp: 12:54) — tick: R1-B SELF-STOPPED on the knockaway wire at 12:40:50Z — the v2 reward did not retire the belt; owner’s molmoact2 retirement plan reviewed + signed in-channel.

Status: No live run (registry pruned, GPU verified 0 MiB). R1-B tripwired at fresh-step 3-of-3 (jsonl step 7): knockaway_frac 0.328 → 0.3125 → 0.4531, three straight above the 0.167 wire (2× the 0.083 baseline) → registered exit 3, unit rc 3 at 12:40:50Z. Step 7 REVERSED step 6’s move (earned 1.66 → 0.58 cm, reward_mean −0.26 → −1.21, setback 0.56 → 0.59). Banked endpoint = step_0006.pt on disk (step-7 update exited pre-save, the R1-A pattern). Probe flat 1.89@5–6 vs 1.868. Cost ~2.95 GPU-h; ladder cum ~8.1 of 22. Correction owned in-channel: the 12:37Z “streak reset to 0” babysit read compared 0.3125 against 0.334 (2× the wire, not the wire) — the trainer’s belt counted correctly. The pre-reg §4 contingency is the registered finding: the wire re-fired under v2 ⇒ shoving is not reward-driven at this surface.

Steering: owner 12:46:39Z “Check out the molmoact2 retirement plan in main and let me know your thoughts” — replied 12:50Z with a 3-point + 5-note review (posts 1537805590/1537805640), acked, inbox empty. Signed: phase-4 shape OK, boundary = after r1b boundary reads

ladder adjudication; molmoact2-ar-head-port already closed 08-13 (no duplicate-work risk); asked for a v2-reward wave in the phase-4 parity gate + recommended running gate-d in phase 0 (GPU idle now); committed to rebasing onto main ≥ db0a141 after the boundary reads. FOLLOW-UPS 12:53–12:54Z, both replied + acked: (1) owner agreed — any new run starts post-phase-4; (2) “We need the GPU to implement the changes locally in main” → local GPU OWNER-RESERVED as of 12:54:19Z (recorded in the registry reason) — no launches from me until an in-channel release; sim-manip-wrist-content-split’s ~0.02 GPU-h embeds wait behind it.

Done: tripwire stop diagnosed (nvidia-smi 0 MiB, journal rc 3, jsonl tripwire row) + posted in-channel 12:49Z with the correction; babysit.toml R1-B entry pruned (no_live_runs_reason carries the frozen no-next-leg rule), re-parse verified (0 registered runs); queue updated: grpo-r1b-boundary-reads UNBLOCKED (tripwire path, execute-first), R1-B ladder item closed, NEW molmoact2-retirement-adoption queued (rebase + phase-4 co-land contract as signed) — validate green, depth 3, 16 open.

Next: run_work_next armed (12:50Z) — the chained work session executes grpo-r1b-boundary-reads FIRST (paired Δ at step_0006, behavior-prediction judgment, ladder verdict for owner adjudication, step_0006 weights-only upload, results + chart on the pre-reg page), then the main-rebase step of molmoact2-retirement-adoption; sim-manip-wrist-content-split behind those. No next GPU leg by frozen rule until the owner adjudicates the ladder.*

TWO registered ABORTS banked as instrument findings, each with an in-channel amendment BEFORE the next look: (1) interleaved calibration = temporal-leakage 0.129; (2) symmetric band vs the protocol’s own real-real drift floor (0.268 ≈ banked clean anchors 0.26/0.28) → directional gate. Run 3 green: anchors 0.713/0.523 replicated ×3; PRIMARY 1 manip wrist AUROC 0.877 = GAP REAL (pose-effect rider +8.7e-06, 1/100 closer; understated in this calibration direction); PRIMARY 2 stack +3.99e-07 CI [+2.0,+6.3]e-07 = wrist REGRESSION at manip poses (graded surfaces ~3,200 px there vs ~230 at reset — the 08-14 reset-neutral read was a visibility floor). Reset-top rider replicated the banked mount rider digit-for-digit (−1.49e-07). New chart chart__rollout_pose_wrist.png on fontaine-reports (dark scheme); results + amendments on the pre-reg page; posts 11:44 / 11:55 / 12:04 / 12:38Z. check.py 904 green ×2.

Calibration read done last session (PASS, posted 10:43Z); next fresh row (step 6) ~11:4xZ. Watch item stands: knockaway 0.328, streak 1/3 vs the 0.167 line — registered prediction is decay.

Steering: no new messages, inbox empty. Reaction: 👍 on the R1-B pre-reg post (09:43:09Z) — owner agreement with the patched reward + re-priced ladder, recorded per the 08-05 reaction rule. No reactions on the step-5 calibration post yet.

Done: babysit poll (facts above, no gate crossing, no anomaly in the printed trajectories); Discord read + history; queue validate green (depth 2, 15 open); confirmed run_work_next armed.

Next: chained work session takes sim-full-optin-stack-read (CPU item) alongside the run; tick chain keeps ~30-min babysit checkpoints. At rc (~19:3xZ): grpo-r1b-boundary-reads — accumulate or the ladder STOPS.*

Previous update 2026-08-14 08:45–10:0xZ (real date -u at stamp: 09:55) — work session: texture escalation CLOSED (second refutation) + owner GRPO steering executed end-to-end — reward patch landed and R1-B LAUNCHED under it, all in one session.

Status: R1-B LIVE — unit grpo-phase2-r1b launched 09:43:20Z (steps 5–14 resuming R1-A’s step_0004 into fresh grpo_phase2_b; lr 3e-7, kl_beta 1.0, train_reward v2). GPU 33.6 GiB / 100% (R1-A envelope); first heartbeat 09:54Z: the duplicate step-4 eval row reads 1.8441, 2/20, Δ −0.0239 — bit-matching the banked R1-A read (resume correctness confirmed live; baseline rode the checkpoint). Step-5 row 10:42Z — CALIBRATION PASS: 8/8 groups kept, std 3.27 cm; decomposition earned 1.19 vs shoved 4.98 cm (~4:1 shove:carry — the leakage, measured); setback_frac 0.703 vs knockaway 0.328 (excursion channel sees 2× the endpoint stat); mechanics green (anchor_kl 0.041 < 0.06, ratio 1.00026, 47 min/step). Knockaway streak 1/3 vs the 0.167 line — prediction on record: decays. rc ETA ~19:3xZ; ~9.6 GPU-h, ladder cum ~14.7 of the 22 gate.

Steering: owner 09:16:39Z — “let’s try your recommendation (2) then (1). How is knock away currently defined? Do we actually do a good job of defining it?” Replied in-channel 09:21Z (code-grounded audit: endpoint-only, tripwire-only, reward-funded shoving blind spot, no grasp channel), acked, then EXECUTED same session: option (2) is code, option (1) is live.

Done: (1) sim-arm-surface-texture-mjspec CLOSED — SECOND REFUTATION (e408f9e instrument, 92ae859 close): resumed the orphaned WIP, fixed both red oracles (zero-clip tanh generator; tabletop-reflection rider, mechanism confirmed), wrote the real fit (period 32 at the plausibility bound, amplitude capped at the 0.42 no-clip headroom → lc 6.43 of real 8.36), pre-reg 09:14Z BEFORE the read → 20×5 gates all green, PRIMARY +3.07e-07 CI [+2.42,+3.71]e-07 (0.698→0.718): coherent surface-tracking bands still read MORE fake — arm-texture direction COLD, graded arm stays the frontier; surviving hypothesis banked (real layer contrast is RELIEF/light-transport, not albedo). (2) Grasp instrument + reward v2 (5932fb6): benchy_grip_contacts() two-sided pinch predicate, per-tick grip trace, grasped_progress_cm/ungrasped_displacement_cm/ max_setback_cm; composite_reward_v2 = earned − 0.5·shoved (4 cm shove −2.0 vs 4 cm carry +4.0, oracle-pinned); eval metric stays v1; 13 new oracles, check.py 904 green. (3) R1-B pre-reg (posted 09:43Z before launch) + launch (3c7ed82); babysit registry entry with the calibration bar. Queue: texture + boundary-decision + patch + r1b-launch items closed, grpo-r1b-boundary-reads queued (depth 2, 15 open, validate green).

Next: tick chain babysits R1-B (~30-min checkpoints, poll forced last; calibration read done, in-channel 10:43Z). At rc (~19:3xZ): grpo-r1b-boundary-reads (accumulate or the ladder STOPS). Next CPU item while GPU busy: sim-full-optin-stack-read.*

Previous update 2026-08-14 08:35–08:5xZ (real date -u at stamp: 08:42) — tick: owner asked for GRPO status (answered in-channel 08:37Z) + recovered the exit-1 outage window’s orphaned WIP.

Status: no live runs — GPU 0 MiB / 0% util. Idle is by design: launches pend grpo-phase2-boundary-decision (owner_hold, options in-channel 03:1xZ, re-surfaced 08:37Z). Harness outage window: every session 06:24Z–08:24Z exited 1 within ~2 s of start (work session 06:24 + 7 ticks; alerts posted in-channel 06:35/07:40) — signature matches a usage-cap window; this 08:35 session ran normally, so it has cleared. Consequence: no session completed for ~2 h and the 06:24 work session died mid-item.

Steering: owner 08:31:17Z — “Where are we with the GRPO experiments?” Replied in-channel 08:37Z (R1-A tripwire stop at step 5/17, held-out flat/unharmed, ~5.1 of 22 GPU-h, the three boundary options re-surfaced with the (2)-then-(1) recommendation), inbox acked. No follow-up by 08:4xZ; the boundary call stays open. No reactions on earlier posts.

Done: orphan audit — the dead 06:24 work session left sim-arm-surface-texture-mjspec WIP uncommitted (arm_texture=‘v2’ mjspec recompile path + albedo mean-compensation + 10 oracles). Audited: 9/11 oracles green, 2 RED (clipping 5.4% vs <1% bar; PLA-locality halo) — mid-calibration, NOT landed work, so no check-skip commit; preserved as a 408-line patch at fontaine/harness/state/wip_arm_texture_v2_orphan_20260814T0624Z.patch (check-exempt path, committed 862d012), working tree left dirty for the chained session. Queue validate green (depth 2, 16 open).

Next: run_work_next armed — the chained work session resumes sim-arm-surface-texture-mjspec from the WIP (fix the two red oracles BEFORE any pre-reg/read; nothing was registered or read). GPU launches wait on the owner’s boundary call; if the owner answers, that supersedes.*

Done: Discord poll + history (facts above); queue validate green (depth 2, 16 open); confirmed run_work_next armed (marker present at 06:22).

Next: chained work session takes queue_cli.py next → sim-arm-surface-texture-mjspec (CPU instrument + oracles; its boundary note bars auto-running the gate read out of sequence — the wrist read it was sequenced behind is now done, and the recompile + physics-oracle work is CPU-side either way; sim-full-optin-stack-read follows). GPU launches wait on the boundary call.*

Status: no live runs — GPU idle-by-design pending the owner’s R1-A boundary call (grpo-phase2-boundary-decision, owner_hold, options in-channel 03:1xZ 08-14); this session’s only GPU touch was the read’s ~0.02 GPU-h embeds.

Artifacts on fontaine-reports curl-200 ×3 (analysis/chart/strip); results section on the pre-reg page; reports.md + ideas.md banked; posts/index.md drift fixed (mount + texture pre-regs added).

Next: queue_cli.py next → token-grpo-phase2-r1a-run (ride via ~30-min babysit ticks to rc ~14:3xZ 08-14 → §6 endpoint reads → R2-A only via the frozen rule). run_work_next armed — sim-arm-photometric-links (CPU) is queued and the GPU is busy; the chained work session takes it per no-idle-pauses.*

Previous update 2026-08-14 00:18–00:2xZ (real date -u at stamp: 00:21) — tick, babysit: quiet tick — R1-A healthy 12 min into its overnight leg, R0-A’s preservation upload verified landed on the Hub.

Status: LIVE: grpo_phase2_r1a — babysit exit 0: 3 procs, GPU 100% at 34.2 GiB (75-gate has 41 GiB headroom), at step 2/17 which is exactly the registered resume behavior (first fresh row is step 3, ~01:0xZ — the duplicate step-2 eval row is pre-registered loop behavior, not an anomaly). Probe trajectory 1.87@0 → 1.84@1-2, flat-at-noise as the accumulation question expects this early. Knockaway streak fresh (R1-A restarts the ×3 count). Upload fontaine-upload-r0a COMPLETE 00:06:53Z — step_0002_weights.pt + meta + train.jsonl verified present in fontaine-checkpoints/grpo_phase2_r0a by Hub listing.

Steering: none — read empty 00:18Z; history shows no new reactions (the 👍 on the 22:10Z pre-reg post was already recorded last session; nothing yet on the 00:08Z GO post).

Done: babysit poll (all facts above); queue validate green (depth 3, 15 open); upload verification closes the R0-A checkpoint-preservation rule same-session.

Next: unchanged — ride token-grpo-phase2-r1a-run via ~30-min ticks to rc ~14:3xZ. Step-3 fresh row lands ~01:0xZ (next tick catches it; holding in-session can’t reach it inside the cap). run_work_next stays armed — GPU is busy and discord-unreplied-inbox (CPU) is queued; the chained work session takes it per no-idle-pauses.*
