Archived 15 entries (Recent decisions 14, Tried and abandoned 1) oldest-first to archival-memory.md; 5 held back on the open-deferred-work guard and 164 on the 14-day guard, so the index stays over the soft cap at 477 lines. An over-cap file that keeps live decisions beats a scannable one that lost a belayed item. Four new detail files cover the day: the ops log and its four self-inflicted failure modes, the Booth's two dead controls and the four-iteration layout probe, the Gitea org grant plus the dead claude-bot token that had been misreporting permissions, and the disk triage that rescued a LoRA adapter from a directory this box sweeps at three days. lv-mccarthy's run outcome remains unverified after two days and is the first line of the in-flight section and step 1 of the handoff.

[2026-09-21] nh3-dev disk triage: 27 GB reclaimed, and a LoRA adapter rescued from a directory the box sweeps every 3 days
Beszel alerted root >85%. Reclaimed 7 GB from regenerable caches (uv cache prune, npm, pip), then a deep dive found the real shape.
⚠⚠ The headline was not disk. /tmp held 19 GB of Claude Code session
scratchpads, and inside one of them sat the babyyarros LoRA adapter —
252 MB, r=32/α=64 on Qwen3-4B-Instruct, with its loss series and provenance —
existing nowhere else: not on /mnt/smithy, not under ~/development.
/etc/tmpfiles.d/tmp.conf sets D /tmp … 3d, an admin file from 2026-07-18
that overrides the stock no-age rule, and the cleaner runs daily.
Rescued to /mnt/smithy/adapter-rescue/babyyarros-20260921, verified by
content: sha256 63fda6cc… matching both the source and the adapter.sha256
recorded at training time.
⚠ Two corrections I made to myself during the dive, both worth keeping: I
alarmed that shutterchute's RAW deliverables were 19 hours from deletion — their
mtimes were that day, a live session working. And I suspected my own du/
find had reset the atime clock and manufactured the "0 would-remove" result;
it had not (relatime, and an untouched comparison file still showed an old
atime) — but it was right to check before trusting a number my own measurement
could have created.
Operator-authorized deletions: 7.6 GB duplicate Qwen base shards, 12 GB
models-staging/retro-diffusion (cold since 09 Aug), 7.5 GB splat-assets
(cold since 15 Aug), 178 session dirs idle 7d+. 39 GB → 66 GB free, 84% →
72%.
⚠⚠ MY PRUNE DELETED AN ACTIVE SESSION'S DIRECTORY. -mtime +7 on a session
dir is an unsound liveness test: a directory's mtime does not change when
files are written into its subdirectories. dfacccde/ looked 7+ days idle
while dfacccde/tasks/ was being written continuously. Cost: one lost tool
output; recreated. All four of my safety assertions (right root, right depth,
own session excluded, shutterchute excluded) passed — I checked the paths were
right and never checked the liveness test was sound. Do not re-run that
predicate. A correct version checks the deepest recent file, or
cross-references running claude PIDs.
Also found: sudo -n requires a password as lkraven locally on nh3-dev,
while ssh infra-ops@localhost has NOPASSWD.
