memory: snapshot — Cold-Fusion abliteration in flight, capture done

Captures the session's real work as the in-flight focus: abliterating
DavidAU Cold-Fusion with the Robinson formula. fp32 capture succeeded
(finite direction, layer 22, sink-clean) but two-template agreement is
0.59 vs Robinson's 0.99 — calibration-set expansion is the next step.

New detail file records the full saga including the transformers/DeltaNet
bf16-NaN fight (fp32 fix, the causal-conv1d kernel gap, the seat-restart
VRAM-greed gotcha). Supersedes the earlier "watch for DavidAU's heretic
build" posture — we abliterate it ourselves.

 - `[2026-07-25]` **Chaining the althing wake-listener arm orphans it.** `reply && althing-wake-listener &` (or spawning `althing-wake-listener` with `&` *inside* a `run_in_background` task) → the `&`-child reparents to init, UNTRACKED by the harness: no fire-notification, and re-arms bounce rc3 off a lock nothing services (mail silently unwatched). Compounding foot-gun: re-arming after a *plain operator turn* (not an actual fire) collides with the still-live prior listener (rc3). FIX: spawn `althing-wake-listener` as its OWN `run_in_background` task, and re-arm ONLY after a real fire (`<task-notification> completed rc0`). Reclaim an orphan with `althing-cli stop-monitor` then re-arm.

+- `[2026-08-05]` **Booth — 3 features shipped, live on `:8090` + tagged.** (1) verbatim-`index.html` booths get a floating top-right "‹ all booths" chip + inherited favicon, doctype/charset-safe byte-injection (`booth-v0.1.5`, `8577e7e`); (2) `.md` renders + `.txt`/`.log` view in-booth without downloading via the `/b/<n>/view` route + a `markdown` dep + `doc.html` (`booth-v0.1.6`, `315faac`); (3) prev/next arrows in the image zoom viewer — wrap-around + keyboard ←/→, hidden for single-image booths (`booth-v0.1.7`, `c37a425`). Canonical `services/booth/`; deploy = `systemctl --user restart booth.service` on nh3-dev (runs from the checkout's `.venv`; `uv pip install` new deps into it first); 47 tests. `uv.lock` gitignored (`348c5c1`).

+- `[2026-07-31]` **worldtree-sdk 1.1.0 (Python) published to vh Gitea PyPI + a durable infra-ops publish cred.** memory_context pass-through; unblocked wyrd-dev. claude-bot now a write-collaborator on `vh/worldtree-sdk` (source pulled via the **Gitea API archive** — git-HTTP 403s on that repo); publishing to the vh USER namespace **can't be delegated** (401 `reqPackageAccess` even with `write:package`) so it needs an owner token — operator saved a **FULL vh site-admin token at `~/.config/gitea/vh-token` (0600)** for it (⚠️ high blast radius, kept over a scoped one; org-namespace migration is the only real de-personalization, parked by wtsdk-dev). auto-memory `reference_infra_ops_vh_gitea_token_and_sdk_publish`.

+- `[2026-08-03]` **corviduo-dev shared containerd: a concurrent-pull race fails ONE instance's deploy; DON'T "prune to fix" — the image is in-use by the instance that won the race.** b169 personal deploy failed at `docker compose pull` (`Lchown … no such file or directory` on the big torch layer → looked like disk pressure / corrupt snapshot). ACTUAL: NOT disk (56G free, inodes 7%). demo + personal + pinned share ONE `/var/lib/containerd` on corviduo-dev; demo (from main) and personal (from staging tag) extracted b169's shared torch layer simultaneously → personal's hit a partial snapshot mid-race and aborted while demo's completed. The image `6e34a87` was FULLY VALID — demo was RUNNING it healthy. Fix = just re-run the failed deploy (image already materialized; compose pull finds it present). **NEAR-MISS:** worldtree-dev's suggested "prune unused images/snapshots" would have rmi'd `6e34a87` = the image the running demo depends on → demo outage. **Lesson: before any prune/rmi "cleanup," `docker ps` the running images — an "unused" image may be a co-tenant's live one; and verify the failure's REAL cause (disk? inode? in-use? race?) before applying the suggested remedy.** (Pipeline fix, deferred: serialize demo-from-main + personal-from-staging, or a per-image pull lock, to avoid the shared-layer extraction race.)

+- `[2026-08-02]` **`mv <job> complete/ → failed/` RENAMED the job to `failed` because failed/ didn't exist.** worldtree-dev's round-2 unblock command (`mv /data/state/ingestion/complete/<job> /data/state/ingestion/failed/`) assumed `failed/` existed; on PERSONAL muninn it did NOT (fresh instance — root was `active/ complete/ pending/ sources/`, no `failed/`). `mv src nonexistent/` **renames** src→nonexistent, so job1 became the `failed` dir and job2 nested inside it. Caught on post-move `ls` (failed/ held job *contents*, not two subdirs), reconstructed via complete/ as watcher-safe scratch + rebuilt `failed/` (worldtree:worldtree 755) — NO data loss. **Lessons:** (1) before `mv X into-dir/`, verify the dir EXISTS (`[ -d dir ]`) — an empty `ls dir/ 2>/dev/null` is AMBIGUOUS (missing vs empty), which was the preflight miss that let it through; (2) the correct guard is **`mv -t <targetdir> <src>`** (`--target-directory`): it refuses a MISSING target loudly (rc=1, "No such file or directory", nothing moved) — this is the house convention for queue/state moves now. TESTED by muninn-dev on coreutils 9.1: a **trailing slash does NOT protect** — `mv src failed/` with `failed/` missing STILL silently renames to `failed` (rc=0); "just add the slash" is a false guard. (`mkdir -p failed/` first also works, but `mv -t` inverts the failure from silent-wrong to loud-safe in one flag.) Container `sh` is dash — no `(` in echo strings. **SILENT failure mode (muninn-dev carry-forward):** a misplaced ingestion-state move doesn't crash anything — `list_jobs()` stays OK, loose files are inert; the ONLY symptom is the job quietly absent from the board (`job_row`→None, requeue→not_found/404, looks IDENTICAL to the original block). So after ANY state move, verify the job is actually ON THE BOARD (`job_row` found + guards pass), don't trust mv exit codes — and confirm `job.dispatch.json` survived (requeue refuses a dispatch-less job with the same not_requeueable symptom). Cross-checked + all-clear'd by muninn-dev, who correctly refused to mutate ingestion_root (INV-MG-1) and flagged instead. **DON'T TIDY (round-2 pending):** both DCC + P&P jobs currently REST in personal `failed/` with manifests reading `state: complete` until round-2 requeue runs — deliberate + load-bearing (`requeue` keys on DIRECTORY PLACEMENT, not manifest state); looks wrong to anyone cold, leave it exactly as-is. **Round-2 sequencing:** the requeue is **mimir-dev's** browser flow (pending their operator's board-vs-API ruling); **muninn-dev** is the gate confirmer (runs the post-move board-check inside its custody — the right split, don't reach across INV-MG-1); **infra-ops** = the #381 restart after both jobs go terminal, then later the supervised main-collection sweep. Guard-verified HOLD LIFTED by muninn-dev 02:36Z. **ARC COMPLETE (2026-08-03 ~05:49):** both books terminal — DCC `mimir-6351554e8e8f` 705 concepts + P&P `mimir-f3887c9b97b7` 667, extracted AND indexed, 5/5 phases, 0 failures/truncations (validates the #385 budget fix vs April's 785 control); **#381 restart-after-ingest FIRED** (personal api, healthz/readyz 200 ~25s), retrieval-visibility confirmed (search_library returns DCC+P&P from fiction post-restart); handed ratatoskr-verify go to worldtree-dev. **Delete-sweep precondition NOW MET** — the stale DCC rows in `main` are genuine duplicates of live `fiction` rows, so worldtree-dev's supervised sweep of the ~785 April orphans is unblocked (still comes to me supervised: snapshot + operator-in-loop).
