Updated 2026-08-23 11:36–12:2xZ (work session) — RETIREMENT: owner message 11:50:09Z — the machine is being retired and all work is PAUSED; this session pivoted from the planned verdict block to evacuation-only and the box is ready to retire. ch0fix train COMPLETED 3000/3000 ~12:02Z (loss 0.2845, ~13.4 GPU-h vs the 16 gate) and the endpoint is banked weights-only on HF; the sim100 battery was stopped pre-verdict — the rung-2 verdict is UNBANKED and waits for a future box.

Status: no live jobs. fontaine-v2-joint-pdnorm-ch0fix train COMPLETE (endpoint verified 44G complete, published ~12:02Z; probe closed 8.34@3000, record-only; vram peak 62.24 ≤ 71). The endpoint battery (armed 11:38Z, started 12:03:09Z) was STOPPED ~12:04Z at the owner pause before any seed completed. GPU free, babysit registry 0 live runs.

Steering: owner 11:50:09Z (id 1541051920825716736): machine retiring, pause work, save all valuable artifacts to GitHub/HF, remove all uploaded optimizers, upload no more, report when ready. Disposition: executed same-session (evacuation receipt below); replied 12:04Z + acked; receipt posted at close.

Done (this session): [pre-pause] battery unit cloned + armed (self-waiting), BOTH rung-3 branch materializers written + run with all oracles green (clean_ch0fix_act_j action-only affine; clean_ep015_c bisection subset via the rig_fewshot machinery), both launchers + upload script staged, check.py 1112 green, commit 0adb8f09. [post-pause] endpoint publish verified + optim@2500 pruned; battery stopped; evacuation: ch0fix endpoint → fontaine-checkpoints/grasp_sft_v2_joint_pdnorm_ch0fix_step3000 (weights-only + train_log); gitignored eval record → fontaine-checkpoints/h100_evac_2026-08-23/ (reports.tar 5.3G, outputs_sim_grpo_r2.tar 17G, outputs_sim_rest.tar 6.5G, outputs_squint_screen.tar 1.1G, outputs_misc.tar 14G incl. the snapdistill_ftrig_4k endpoint + rig_r1_step500 conversion + all launch logs + norm_stats); squint_twin_demos_v1 (123M labeled corpus) → fontaine-sim; optimizer purge: ALL optimizer.pt files AND dangling LFS blobs permanently deleted from fontaine-checkpoints (1 file, 31.4G) and bijou-checkpoints (3 files

  • 16 dangling blobs, ~94G freed); wandb verified synced; demos v1/v2 + grasp_sft_demos_v0 verified already on HF file-for-file; queue → retirement pause (validate green, depth-0 stated reason); babysit registry pruned; tick timer disabled.

Next: NOTHING on this box — program paused. On a future box: (1) re-run launch_ch0fix_endpoint_battery.sh from the HF endpoint → bank the rung-2 verdict vs democlean 8/100 (frozen grid, posts/2026-08-22-prereg-clean-ch0-affine.md); (2) the verdict mechanically selects carrier-hunt rung 3 — both branches committed

  • oracle-verified (posts/2026-08-22-prereg-carrier-hunt-rung3.md); datasets rebuild deterministically from the committed materializers. queue.json carries the full pause record.*

Updated 2026-08-23 11:33–11:4xZ (tick) — pre-completion handoff tick: healthy — step 2900/3000, loss 0.2846 (−0.0027 since 2740, monotone continues), vram 62.24/71, rate 14.958 s/step window (3.9 steps/min). No new probe row (@2750 = 8.70 latest; the endpoint row lands with the save). Train hits step 3000 ~11:59Z with the ENDPOINT publish ~12:0xZ — right at this session’s 12:03Z hard kill, far too tight to verify + launch the battery in-tick — so run_work_next ARMED: the chained 4-h work session catches completion, verifies the endpoint publish, runs the sim100 battery (~3 GPU-h), banks the rung-2 verdict, and executes the rung-3 branch select. Disk 73G flat (endpoint trough ~31G safe).

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 2900/3000 at poll, babysit exit 0 (liveness 5 procs, vram 66641MiB on gpu0, 3.9 steps/min since last sample). Loss 0.2873@2740 → 0.2846@2900 — monotone fall continues into the endpoint. Rate 14.958 s/step window, inside the judged 14.7–24.5 band. No new probe row (series stands at …8.63@2250 → 6.01@2500 → 8.70@2750, band ~6–8.7, within-lineage color only; the decision read is the endpoint sim100 battery vs democlean 8/100). Disk: 73G free, flat vs 10:52 — the step-3000 ENDPOINT staging trough ~31G is safe, no load-bearing prunes remain (post-endpoint optim@2500 prune stays routine). Host RAM available 47G — sixteenth stable-plateau read. Handoff: 100 steps ≈ 25 min to go → step 3000 ~11:59Z, endpoint publish ~12:0xZ, this session’s hard kill 12:03:54Z — holding to verify would leave no comfortable commit margin and the battery + verdict + rung3 select exceed a tick anyway, so the marker is armed and the chained work session (4-h budget) executes the completion block per the pre-reg: verify endpoint publish → sim100 battery → rung-2 verdict → carrier-hunt-rung3-exec branch select + launch (fit smoke → launch, ONE dataset delta, seed 0; 11–19 fires neither branch, owner escalation) → routine optim@2500 prune.

Steering: none — inbox empty, read empty, history -n 5 all own posts, no reactions.

Done (this tick): babysit poll (exit 0), loss/rate/probe reads judged (all in-band, no new probe row), disk read (73G flat, endpoint trough ~31G safe), RAM read (47G, sixteenth), Discord read

  • history (quiet), queue validate (depth 1 — below depth-2 AND the completion block is now imminent, so the standing stated-reason lapses: run_work_next ARMED for the completion work), now.md keep-3 + footer rolls (09:31 entry → archive); no blog rebuild (routine poll precedent, reader-visible content unchanged).

Next: the chained work session owns the completion block — verify the step-3000 ENDPOINT publish (weights + optimizer.pt + metadata + tokenizer, no staging temp), read the endpoint probe row, launch the sim100 battery (~3 GPU-h) via systemd-run, bank the rung-2 verdict vs democlean 8/100, then rung3-exec selects and launches the branch same session; post the completion + verdict to Discord (the quiet-tick precedent ends at completion). Routine optim@2500 prune after the endpoint publish verifies.*

Updated 2026-08-23 10:52–10:5xZ (tick) — routine ch0fix poll + short probe hold: healthy — step 2740/3000, loss 0.2873 (−0.0022 since 2580; 0.2746@2750 during the hold — monotone continues), vram 62.24/71, rate 15.093 s/step window (3.9 steps/min). Held ~3 min in-session to catch the @2750 probe row: 8.70 — a NEW series high (…7.41 → 8.63 → 6.01 → 8.70) — the oscillation band widens to ~6–8.7; train_mae co-moves (7.94@2750 vs 5.59@2500), so the swings track eval-batch composition, within-lineage color only. Disk 73G free (−4G drift, endpoint trough ~31G still safe). ETA ~1.0 h → done ~12:0xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 2740/3000 at poll, babysit exit 0 (liveness 5 procs, vram 66641MiB on gpu0, 3.9 steps/min since last sample). Loss 0.2895@2580 → 0.2873@2740 → 0.2746@2750 — monotone fall continues. Rate 15.093 s/step window, inside the judged 14.7–24.5 band. Probe eval_chunk_mae @2750 = 8.70, a new series high (4.61 → 5.24 → 5.97 → 6.84 → 6.62 → 5.55 → 6.07 → 7.41 → 8.63 → 6.01 → 8.70): the band is now ~6–8.7 with no monotone trend; the 10:1x “oscillation restored” read stands but with a wider envelope. New observation this tick: train_mae co-moves with the probe (7.94@2750 / 5.59@2500 / 7.87@2250), so the swings look like eval-batch composition, not model drift. Still within-lineage-only per the banked pdnorm-rescale confound — decision read stays the endpoint sim100 battery vs democlean 8/100; carry the full series + the train_mae-co-movement note as verdict-session color. Disk: 73G free (77G at 10:1x — ~4G drift from logs/wandb, routine). Checkpoint dir verified by file listing: step_000500/1000/1500/2000 weights-only, step_002500 full with the single optimizer.pt (32G), no staging temp — exact keep-1 anchor. Endpoint staging trough from 73G ≈ ~31G — safe, no further load-bearing prunes (post-endpoint optim@2500 prune stays routine). Host RAM available 47G — fifteenth stable-plateau read. ETA 250 steps at ~15 s/step ≈ 1.0 h → done ~12:0xZ 08-23 → sim100 endpoint battery; its verdict mechanically selects the rung-3 branch.

Steering: none — inbox empty, read empty, history -n 5 all own posts, no reactions.

Done (this tick): babysit poll (exit 0), short in-session hold (~3 min) to catch the @2750 probe row, probe read judged (new series high 8.70, band widened, train_mae co-movement noted — within-lineage, non-actionable, verdict-session color), disk read (73G, −4G routine drift, endpoint trough re-projected ~31G safe) + checkpoint dir verification (exact keep-1, single optimizer.pt at step_002500), RAM read (47G, fifteenth), Discord read + history (quiet), queue validate green (depth-1 stated reason — rung3-exec verdict-gated, no CPU items, so run_work_next stays unarmed), now.md keep-3 + footer rolls (08:49 entry → archive); no blog rebuild (routine poll precedent).

Next: nothing load-bearing before the boundary — the step-3000 ENDPOINT save stages ~12:0xZ into a ~31G trough (safe). Train done ~12:0xZ 08-23 → the completion tick runs the sim100 battery (~3 GPU-h) → rung-2 verdict banks → carrier-hunt-rung3-exec selects and launches the branch same session (fit smoke → launch, ONE dataset delta, seed 0; 11–19 fires neither branch, owner escalation). Post-endpoint tick also verifies the endpoint publish and prunes optim@2500 (routine class). The ~11:3x/12:0x tick is likely the completion tick — budget for battery launch + verdict write-up.*

Session 2026-08-23 11:36–12:2xZ (work session; ~0.05 marginal GPU-h — the battery’s ~1 min of seed-0 rollouts before the stop): exploit (the planned verdict block) pivoted to RETIREMENT EVACUATION at the owner’s 11:50:09Z pause. ch0fix train completed 3000/3000 (~13.4 GPU-h total vs the 16 gate, all in earlier notes’ wall-clock); endpoint banked weights-only to HF; battery stopped pre-verdict. Evacuated: 44G of gitignored eval record + the ftrig endpoint + squint corpus to HF; ALL uploaded optimizers + dangling LFS blobs permanently purged (~125G freed across two repos). Rung-2 verdict + rung-3 launch wait for a future box — both branches committed + oracle-verified. FINAL session note on this machine.

Session 2026-08-23 11:33–11:4xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): **pre-completion handoff tick, healthy — step 2900/3000, loss 0.2846 monotone, vram 62.24/71, rate 14.958 s/step (3.9 steps/min). No new probe row (@2750 = 8.70 latest). Disk 73G flat (endpoint trough ~31G safe); RAM 47G sixteenth read. Step 3000 lands ~11:59Z with the ENDPOINT publish ~12:0xZ — at this session’s hard kill — so run_work_next ARMED: the chained 4-h work session verifies the endpoint publish, runs the sim100 battery (~3 GPU-h), banks the rung-2 verdict, and executes the rung3-exec branch select

  • launch; routine optim@2500 prune rides along.**

Session 2026-08-23 10:52–10:5xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll + short probe hold, healthy — step 2740/3000, loss 0.2873 → 0.2746@2750 monotone, vram 62.24/71, rate 15.093 s/step (3.9 steps/min). Held ~3 min to catch probe @2750 = 8.70 NEW series high (…8.63 → 6.01 → 8.70) — band widens to ~6–8.7, train_mae co-moves → eval-batch composition, within-lineage color only. Disk 73G (−4G routine drift, endpoint trough ~31G safe), checkpoint dir verified = exact keep-1 state; RAM 47G fifteenth read. ETA ~1.0 h → ~12:0xZ 08-23 → sim100 battery → rung3-exec branch select; queue depth-1 stated reason (rung3-exec verdict-gated), no CPU items → run_work_next stays unarmed.

Trailing-7-day GPU-hours on experiments / total (window 2026-08-12 00:00Z → 2026-08-19 08:45Z; rolled 08-19 from the 08-17 rebase + prune records + archive session notes — receipts in fontaine/notes/util-window-roll-2026-08-19.md, instrument fontaine/scripts/util_ledger_extract.py): local ~84.1 / ~85.5 (retained 08-12→stamp ~57.5 + post-stamp ~28.1: discriminator roll-in ~4.8, pdnorm screen-wide ~15.9 train+battery, joint-probe legs 3+4 ~3.9 incl. leg 4 live at stamp; ops/loss ~1.4 = discriminator attempt-1 OOM + smokes).
