Now archive — 2026-08-23

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

Updated 2026-08-23 04:43–04:4xZ (tick) — routine ch0fix poll: healthy — step 1380/3000, loss 0.3907 (−0.0049 since 1220, monotone continues), vram 62.24/71, rate 16.267 s/step window (3.9 steps/min). Probe @1250 written: 6.62 — the first DOWN move in the series (4.61 → 5.24 → 5.97 → 6.84 → 6.62), within-lineage record only. Disk 112G flat, RAM 48G stable sixth read. Pre-save tick: the step-1500 save lands ~05:17Z → trough ~70G safe; the NEXT tick verifies it and prunes optim@1000 per the keep-1 anchor. ETA ~7.3 h → ~12:0xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 1380/3000, babysit exit 0 (liveness 5 procs, vram 66581MiB on gpu0; the instant util read sampled 0% but steps advance at 3.9/min and the window rate is in-band — sampling artifact, not starvation). Loss 0.3956@1220 → 0.3907@1380, monotone resumed-and-holding. Rate 16.267 s/step window, inside the judged 14.7–24.5 band. Probe eval_chunk_mae @1250 = 6.62: first decrease after four rising rows (4.61 → 5.24 → 5.97 → 6.84 → 6.62) — still within-lineage record only per the banked pdnorm-rescale confound; decision read stays the endpoint sim100 battery vs democlean 8/100. Disk: 112G free, flat since the 04:0x read (ambient drift paused); next save step 1500 (~05:17Z at the window rate) stages 42G → trough ~70G, safe per the keep-1 registry anchor, then the post-save tick deletes superseded optim@1000. Host RAM available 48G — sixth stable read. ETA ~7.3 h at the window rate → 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), probe @1250 first-downtick read judged (within-lineage, non-actionable), pre-save disk read (112G flat, trough projection reconfirmed), RAM read (48G sixth stable), Discord read + history, 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 (02:41 entry → archive).

Next: the ~05:2xZ tick verifies the step-1500 save (staged ~05:17Z) and executes the keep-1 prune (optim@1000 becomes superseded). Otherwise nothing fires before the ch0fix boundary — train done ~12:0xZ 08-23 → 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).*

Footer note (rolled 06:4xZ 08-23): Session 2026-08-23 04:43–04:4xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll, healthy — step 1380/3000, loss 0.3907 monotone, vram 62.24/71, rate 16.267 s/step. Probe @1250 = 6.62 — first DOWN move in the series (…5.97 → 6.84 → 6.62), within-lineage record only. Disk 112G flat, RAM 48G stable sixth read. Pre-save tick: step-1500 save ~05:17Z → trough ~70G safe, next tick prunes optim@1000 per the keep-1 anchor.

Updated 2026-08-23 04:02–04:0xZ (tick) — routine ch0fix poll: healthy — step 1220/3000, loss 0.3956 (−0.0894 since 1060: the 03:2x window uptick cleared as noise, monotone resumed), vram 62.24/71, rate 14.821 s/step window (3.9 steps/min). Probe @1250 row not yet written. First post-mitigation disk read: 112G free, checkpoint dir verified matching the keep-1 rule (step_000500 = 13G optim-pruned, step_001000 = 42G newest intact); next save at step 1500 (~05:1xZ) stages 42G → trough ~70G, then that tick prunes optim@1000. RAM 48G stable. ETA ~7.3 h → ~11:2xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 1220/3000, babysit exit 0 (liveness 5 procs, gpu0 66581MiB/100% util), vram 62.24 stable vs the 71 gate. Loss 0.485@1060 → 0.3956@1220: the first-window uptick judged noise-class last tick is confirmed noise — the fall resumed steeper than the wobble. Rate 14.821 s/step window, inside the judged band. Probe eval_chunk_mae still 4.61@250 → 5.24@500 → 5.97@750 → 6.84@1000 (@1250 not yet written; within-lineage record only, decision read = endpoint sim100 battery vs democlean 8/100). Disk: 112G free vs 115G at the 03:2x prune — ~3G ambient drift (logs/wandb), floors unaffected; checkpoint dir audited and matches the banked keep-1 state exactly. Next save step 1500 lands ~05:1xZ → trough ~70G (safe), then the post-save tick deletes superseded optim@1000 per the registry anchor. Host RAM available 48G — fifth stable read. ETA ~7.3 h at the window rate → done ~11:2xZ 08-23 → sim100 endpoint battery; its verdict mechanically selects the rung-3 branch.

Done (this tick): babysit poll (exit 0), loss-uptick resolution read (noise confirmed, monotone resumed), first post-mitigation disk read + checkpoint-dir audit vs the keep-1 anchor (matches: 13G/42G), RAM read, Discord read + history, 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 (01:59 entry → archive).

Footer note (rolled 06:1xZ 08-23): Session 2026-08-23 04:02–04:0xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll, healthy — step 1220/3000, loss 0.3956 (the 03:2x window uptick confirmed noise, monotone resumed), vram 62.24/71, rate 14.821 s/step. First post-mitigation disk read: 112G free (~3G ambient drift from 115), checkpoint dir audited matching the keep-1 anchor (step_000500 13G optim-pruned, step_001000 42G intact); next save step 1500 ~05:1xZ → trough ~70G safe, that tick prunes optim@1000. RAM 48G stable. ETA ~11:2xZ 08-23; queue depth-1 stated reason (rung3-exec verdict-gated), no CPU items → run_work_next stays unarmed.

Updated 2026-08-23 03:22–03:3xZ (tick) — ch0fix healthy + a disk projection CORRECTED and acted on: prune_superseded_optimizers is keep=2 and runs strictly AFTER publish (stage-then-prune), so the 01:18 trough projection (≈82→34G, reclaim-before-staging) was wrong — real troughs from the measured 84G floor ran ~40/28/16/4G, the ~4G at the step-3000 ENDPOINT staging (leg B ENOSPC class, aimed at the one save the rung needs). Mitigation: optimizer.pt is dead weight on this lineage (no-resume anchor — recovery is full retrain), so superseded optims are manually pruned each post-save tick (keep-1, newest save untouched): optim@500 deleted → 115G free, projected troughs ~72/60/48/36G all safe; registry anchor rewritten, posted in-channel (id 1540924939014504519). Run itself: step 1060/3000, loss 0.485 (first window uptick +0.042 — noise-class), vram 62.24/71, 16.4 s/step window; probe @1000 = 6.84 (4.61 → 5.24 → 5.97 → 6.84, within-lineage record only). ETA ~12:1xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 1060/3000, babysit exit 0 (liveness 5 procs, gpu0 66581MiB/100% util), vram 62.24 stable vs the 71 gate. Loss window 0.4429@910 → 0.485@1060 (+0.042) — the first non-monotone sampled read; instant log values at loss ~0.45–0.49 wobble at this scale, judged noise-class (watch, not act). Rate 16.388 s/step window (3.7 steps/min) — inside the judged 14.7–24.5 band. Probe eval_chunk_mae 6.84@1000 continues the monotone rise; per the pre-reg anchor the decision read stays the endpoint sim100 battery vs democlean 8/100. Disk — corrected projection: step_001000 save landed ~03:06Z (42G; async, 62.9 s behind the boundary) → 84G free, matching the old projection’s number but NOT its mechanism — the code (bijou/train/saving.py keep=2, prune strictly post-publish) never reclaims before staging, so the old troughs were unreachable and the real endpoint-staging trough was ~4G. Superseded optim@500 deleted (32G, dead weight under the no-resume anchor) → 115G free; standing per-tick rule banked in the registry: after each save verifies, delete the newly-superseded optimizer.pt (troughs ~72/60/48/36G; even a missed tick still clears a save with ≥28G). Host RAM available 48G — stable fourth read. ETA ~8.8 h at the window rate → done ~12:1xZ 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), step-1000 save verified on disk, trough-projection audit against the actual saving.py semantics (keep=2, stage-then-prune — 01:18 projection corrected), superseded optim@500 pruned (+32G → 115G), registry DISK anchor rewritten with the keep-1 per-tick rule, correction posted in-channel, probe @1000 + loss-uptick reads judged, RAM read, Discord read + history, 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 (01:18 entry → archive).

Next: post-save ticks execute the keep-1 optim prune (next: optim@1000 becomes superseded when the step-1500 save verifies, ~05:2xZ). Otherwise nothing fires before the ch0fix boundary — train done ~12:1xZ 08-23 → 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).*

Footer note (rolled 05:3xZ 08-23): Session 2026-08-23 03:22–03:3xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): ch0fix healthy — step 1060/3000, loss 0.485 (first window uptick +0.042, noise-class), vram 62.24/71, 16.4 s/step; probe @1000 = 6.84 (monotone rise, within-lineage only). DISK PROJECTION CORRECTED: saving.py is keep=2 stage-then-prune, so the 01:18 troughs (82→34G) were unreachable — real endpoint-staging trough was ~4G (ENOSPC class). Superseded optim@500 deleted (dead weight, no resume on this lineage) → 115G free; per-tick keep-1 optim prune banked in the registry, troughs ~72/60/48/36G safe. ETA ~12:1xZ 08-23; queue depth-1 stated reason (rung3-exec verdict-gated), no CPU items → run_work_next stays unarmed.

Updated 2026-08-23 02:41–02:4xZ (tick) — routine ch0fix poll: healthy — step 910/3000, loss 0.4429 monotone down, vram 62.24/71, rate 14.834 s/step window (3.9 steps/min since last sample). Probe @750 row now written: eval_chunk_mae 4.61@250 → 5.24@500 → 5.97@750 — monotone rise, within-lineage record only (pdnorm-rescale confound banked; the decision read stays the endpoint sim100 battery). Disk 126G flat pre-save (step 1000 save ~20 min out, trough projection governs); RAM available 48G unchanged. ETA ~8.6 h → ~11:1x–12:4xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 910/3000, loss 1.91→0.4429 monotone down (−0.0453 since step 750), babysit exit 0 (liveness 5 procs, gpu0 66581MiB/100% util), vram 62.24 stable vs the 71 gate. Probe eval_chunk_mae 4.61@250 → 5.24@500 → 5.97@750: a monotone within-lineage rise while train loss falls monotone — the familiar probe-decoupling shape, and the banked pdnorm-rescale confound (ch0 ×2.755 changes the metric’s units) blocks any cross-lineage read; per the pre-reg anchor the decision read is the endpoint sim100 battery vs democlean 8/100, so this is a recorded trajectory, not a signal to act on. Disk 126G free — flat since step_000500, the step 1000 save (~20 min after this poll) stages ~44G then prunes per the banked trough projection (≈82G trough, safe); next tick sees the post-save state. Host RAM available 48G — stable third read, trend-watch holds. ETA: ~8.6 h at the window rate → done ~11:1x–12:4xZ 08-23 → sim100 endpoint battery vs democlean 8/100; its verdict mechanically selects the rung-3 branch.

Rate from the jsonl: last-6 windows 14.97–15.07 s/step, run-mean 16.04 — the 18–21 s creep noted at 23:57 has fully passed. ETA: last-6 pace ~11:2xZ, run-mean ~12:0xZ, wall-clock-effective ~12:4xZ 08-23 → sim100 endpoint battery vs democlean 8/100; its verdict mechanically selects the rung-3 branch.

Footer note (rolled 02:4xZ 08-23): Session 2026-08-23 00:37–00:4xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll, healthy — step 430/3000, loss 0.5514 monotone down, vram 62.24/71, disk 168G; last tick’s 21.3 s/step window cleared as transient (last-6 windows all ~15.0, run-mean 16.04 falling).

Disk dropped 168G→126G free: the step_000500 save landed 00:57 (44G, of which 32G optimizer.pt) — expected, and --prune-superseded-optim is in the launcher, so each new save reclaims the 32G. Projected staging troughs run ~82G (step 1000) declining to ~34G (step 3000 stage) — never near ENOSPC, but the ≥90G anchor line will read breached during staging dips from ~step 1500; judged now so later ticks compare against this projection instead of re-alarming. ETA holds ~11:2x–12:4xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 580/3000, loss 1.91→0.5248 monotone down (flow 0.0165), babysit exit 0 (liveness 5 procs), vram 62.24 stable vs the 71 gate. Probe eval_chunk_mae 4.61@250 → 5.24@500 — within-lineage wobble only, and cross-lineage comparison vs democlean (11.8@250 → 8.1@500) is meaningless anyway: ch0fix’s recomputed pdnorm (ch0 ×2.755) rescales the metric’s units. Disk read: 126G free after the step_000500 save (44G incl. 32G optimizer.pt, landed 00:57); prune math above — per-save weight residue ~12G walks the pre-save floor down ~12G/save, troughs ≈82/70/58/46/34G, all safe; contingency if a future tick sees a worse floor: superseded weight-only dirs are deletable once the next save verifies (democlean precedent — only step_003000 retained).

Otherwise nothing fires before the ch0fix boundary — train done ~12:0xZ 08-23 → 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).*

Session 2026-08-23 08:49–08:5xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll, healthy — step 2290/3000, loss 0.3074 monotone, vram 62.24/71, rate 15.58 s/step (util 100% this poll). Probe @2250 = 8.63 — SECOND consecutive new high (…6.07 → 7.41 → 8.63), last four reads an upward run; within-lineage only, flagged as verdict-session color. Disk 87G flat, checkpoint dir verified = exact keep-1 state; RAM 47G twelfth read. Next save step 2500 ~09:45Z (post this session’s kill) → trough ~45G safe; the ~10:0x tick’s prune of optim@2000 stays LOAD-BEARING (missed → endpoint ~3G ENOSPC). ETA ~12:0xZ 08-23; queue depth-1 stated reason (rung3-exec verdict-gated), no CPU items → run_work_next stays unarmed.

Updated 2026-08-23 09:31–09:5xZ (tick) — routine ch0fix poll + save-boundary hold: healthy — step 2440/3000, loss 0.3122 (+0.0048 since 2290 — first window uptick after the long monotone fall, noise-class), vram 62.24/71, rate 16.489 s/step window (3.6 steps/min, util 87% sampled). No new probe row (@2250 = 8.63 latest; @2500 lands with the save). Disk 87G flat, checkpoint dir verified exact keep-1 state. RAM 47G thirteenth stable read. The step-2500 save lands ~09:48Z — INSIDE this session — so this tick holds at the boundary to attempt the LOAD-BEARING optim@2000 prune itself; fallback stays the ~10:0x tick. ETA ~2.6 h → ~12:1xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 2440/3000, babysit exit 0 (liveness 5 procs, vram 66641MiB on gpu0, util 87% sampled). Loss 0.3074@2290 → 0.3122@2440 — +0.0048, the first window uptick since the 06:4x flat window; same noise class, watch next read. Rate 16.489 s/step window, inside the judged 14.7–24.5 band. Probe eval_chunk_mae unchanged: …6.07@1750 → 7.41@2000 → 8.63@2250 (the @2500 row lands with the save) — the upward run stands at four reads, within-lineage-only per the banked pdnorm-rescale confound, decision read stays the endpoint sim100 battery vs democlean 8/100. Disk: 87G free, flat. Checkpoint dir verified by file listing: step_000500/1000/1500 weights-only, step_002000 full with optimizer.pt (33.7G), no staging temp, no step_002500 dir yet — exactly the keep-1 anchor. Save-boundary hold: step 2500 lands ~09:48Z at the window rate, publish ~09:5xZ — this session holds with sleep-polls to verify the publish and execute the optim@2000 prune (LOAD-BEARING: missed → step-3000 endpoint staging trough ~3G, ENOSPC class). Prune fires ONLY on a verified-complete publish (weights + optimizer.pt + metadata + tokenizer, no staging temp); if staging is still mid-flight at ~09:55Z the session exits clean and the ~10:0x tick executes it per the standing registry anchor. Host RAM available 47G — thirteenth stable read. ETA ~2.6 h → done ~12:1xZ 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), loss uptick judged noise-class (first after long fall, next-read watch), disk read (87G flat) + checkpoint dir verification (keep-1 state, single optimizer.pt at step_002000, no staging temp), RAM read (47G, thirteenth), Discord read + history, 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 (07:27 entry → archive), save-boundary hold attempted (outcome recorded in the headline above).

Next: if this session’s hold caught the publish, optim@2000 is pruned and the ~10:0x tick reverts to a routine poll (verify only); if not, the ~10:0x tick verifies + prunes — LOAD-BEARING either way until executed (missed → endpoint staging trough ~3G ENOSPC). Probe @2500 readable at the save, @2750 en route — watch whether the upward run extends. Otherwise nothing fires before the ch0fix boundary — train done ~12:1xZ 08-23 → 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).*

Session 2026-08-23 09:31–09:5xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): routine poll + save-boundary hold, healthy — step 2440/3000, loss 0.3122 (+0.0048 first uptick after long fall, noise-class), vram 62.24/71, rate 16.489 s/step. No new probe row (@2250 = 8.63 latest, @2500 lands with the save). Disk 87G flat, checkpoint dir verified = exact keep-1 state; RAM 47G thirteenth read. Step-2500 save lands ~09:48Z INSIDE this session — held at the boundary to attempt the LOAD-BEARING optim@2000 prune (verified publish required; fallback ~10:0x tick). ETA ~12:1xZ 08-23; queue depth-1 stated reason (rung3-exec verdict-gated), no CPU items → run_work_next stays unarmed. Previous update 2026-08-23 10:11–10:1xZ (tick) — post-save tick executed: step-2500 save VERIFIED (published 09:49Z, 44G complete — weights + optimizer.pt 32G + metadata step:2500 + tokenizer, no staging temp) and the LOAD-BEARING keep-1 prune fired: optim@2000 deleted → disk 45G → 77G free (projection ~76G, matched). Endpoint staging trough now ~35G — the ENOSPC class is CLEARED. Run healthy: step 2580/3000, loss 0.2895 (−0.0227 since 2440 — the 09:31 uptick resolved as noise, monotone resumed), vram 62.24/71, 16.837 s/step in-band. Probe @2500 = 6.01 — the four-read upward run BROKE (…7.41 → 8.63 → 6.01), series back to oscillation ~6. ETA ~2.0 h → ~12:1xZ 08-23.

Status: fontaine-v2-joint-pdnorm-ch0fix LIVE and healthy — step 2580/3000, babysit exit 0 (liveness 5 procs, vram 66641MiB on gpu0, util 85% sampled, 3.4 steps/min). Loss 0.3122@2440 → 0.2895@2580 — −0.0227, the 09:31 uptick resolved as noise-class, monotone fall resumed. Rate 16.837 s/step window, inside the judged 14.7–24.5 band. Probe eval_chunk_mae @2500 = 6.01 — the upward run broke (4.61 → 5.24 → 5.97 → 6.84 → 6.62 → 5.55 → 6.07 → 7.41 → 8.63 → 6.01): what read as a four-read upward drift at 08:4x now reads as oscillation ~6–8.6 with no trend; 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 as verdict-session color. Save + prune (the load-bearing item): the 09:31 session’s in-session hold did NOT catch the publish (exited clean per its contract); this tick executed the fallback per the registry anchor. step_002500 verified complete by file listing (backbone_text 8.3G + backbone_vision hardlink + flow_decoder 2.4G + metadata step:2500 + optimizer.pt 32G + tokenizer, all 09:49Z, no staging temp), then optim@2000 deleted → 45G → 77G free (projection ~76G — matched). Remaining trough: ~35G at the step-3000 ENDPOINT staging — safe, no further load-bearing prunes; the post-endpoint prune of optim@2500 is routine housekeeping. Host RAM available 46G — fourteenth stable-plateau read. ETA 420 steps at 16.837 s/step ≈ 2.0 h → done ~12:1xZ 08-23 → sim100 endpoint battery; its verdict mechanically selects the rung-3 branch.

Done (this tick): babysit poll (exit 0), step-2500 publish verified complete + LOAD-BEARING optim@2000 prune executed (45G → 77G, projection matched, ENOSPC class cleared), probe @2500 read judged (upward run broke, oscillation restored, within-lineage non-actionable), loss read (uptick resolved as noise, monotone resumed), RAM read (46G, fourteenth), Discord read + history, 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 (08:08 entry → archive), blog rebuild + Space upload (post-save precedent).

Next: nothing load-bearing remains before the ch0fix boundary — the step-3000 ENDPOINT save stages ~12:0xZ into a ~35G trough (safe). Probe @2750 readable en route — watch the oscillation. Train done ~12:1xZ 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).*

Session 2026-08-23 10:11–10:1xZ (tick; 0 marginal GPU-h — ch0fix riding gpu0): post-save tick executed — step-2500 save verified (published 09:49Z, 44G complete, no staging temp) and the LOAD-BEARING keep-1 prune fired: optim@2000 deleted → 45G → 77G free (projection ~76G matched).
