the file browser's thumbnailer read what sharp and ffmpeg read, and that list was a constant in core. HEIC forced the question: sharp's bundled libheif has no HEVC decoder, and teaching core to shell out to ImageMagick means the PLATFORM acquiring a system dependency for one format. that is a plugin's job. so a manifest may declare `fileTypes` — extensions, plus a thumbnail path and a render path on its own sidecar. `ls` unions those with core's, so a file only promises a thumbnail when something can actually produce one. `/thumb` forwards a claimed type to whoever claimed it. CORE DOES NOT KNOW av-club EXISTS. it reads a claim at runtime from whatever is installed and enabled, calls a path by name, and falls back to a file icon when nothing claims the type. no import, no name, no special case. PROVEN BY DISABLING IT: heic reports thumb=image with av-club enabled, thumb=none disabled, image again re-enabled. that is the whole requirement — the file browser is what it was without the plugin — and it is a test rather than a claim. the plugin's bytes are cached by CORE, under the same key everything else uses, so a HEIC thumbnail is produced once and then served from disk like any other. that is why `buildThumbnail` takes a producer rather than there being a second path beside it: the cache key with its mtime and size, the concurrency cap and the remembered failures all live in that one function, and a parallel path would be a second place to forget the negative caching. TWO THINGS FOUND BY WIRING IT UP. a claimed-but-not-running sidecar is skipped rather than recorded, or `ls` promises a thumbnail that cannot be fetched while a plugin restarts. and the sidecar authenticates: it accepts `x-officer-user` from anything on loopback, by its own design, so core sends the account the request is FOR — passing anything else would be lying to a plugin that scopes per user. verified: HEIC 2 MB in, 12 KB out, 5.4s cold and 101ms cached; png and mp4 unchanged; 1665 tests; docs:check green.

The documentation, triaged
2026-08-13. A map of what is in here, what it is for, and what should happen to it. Made because there are 42 documents and 13,000 lines, and no way to tell from the filenames which describe the system as it is and which are a record of an afternoon in July.
How much I verified: the classifications below are from filenames, status lines, and greps for things that changed on 2026-08-13. Where I actually read the document or checked the code, it says so. The rest is a starting point for a conversation, not a verdict.
Living — these describe the system and must stay true
| doc | state |
|---|---|
working-on-officer.md |
updated 2026-08-13. Operational guide. |
secret-store.md |
updated 2026-08-13. Built; rotation still open. |
install-variants.md |
new. The branch tree, for discussion. |
http-secure-context-audit.md |
new. What breaks over plain http. |
install-container-testing.md |
new. First container pass and its findings. |
per-user-linux-accounts.md |
partly updated. OFFICER_OS_USERS is gone; check the rest. |
navigation-audit.md |
authoritative on routing. Unverified against tonight's route removals. |
workspace-panels.md + workspace-panel-todo.md |
the panel framework. 1,300 lines combined — likely the biggest cleanup here. |
agent-coordination.md |
the north star for panel work. |
deprovision-os-account.md |
implemented; the 'disabled' stage it may mention was deleted tonight. |
Stale — describe things that changed on 2026-08-13
Each of these references something that no longer exists. Not yet corrected.
sidecar-topology.md— "ecosystem.config.cjs is the source of truth". It is generated now, and holds six processes.sidecar-app-store.md— derives the catalogue fromfull − light. Those files are gone, andcatalogue.test.tswas rewritten.sidecar-bootstrapping.md— "20 PM2 entries, 18 sidecar dirs". Six entries now.mobile-api-keys.md— partly corrected; recheck the origin-checking claims.wallet-key-custody.md—VAULT_STORE_KEYis now the per-purposewalletkey.push-notifications.md— "agreed design, 2026-07-31". Notify is a plugin and unmounted.chat-session-lifetime.md,chat-ui-walkthrough.md— referenceofficer-agent, renamed.
Historical — a record of a moment, and should stay one
Do not rewrite these to match today's code. They document how a decision was reached, and editing them destroys the reasoning. If they mislead, add a dated header pointing forward.

The opencode cluster — nine documents for one migration
opencode-fork-decision · -parity · -api-2-assessment · -phase0-review · -phase1-report ·
-phase1-review · -serve-migration-plan · -serve-path · -testing-checklist
The migration landed — opencode serve is in the sidecar, verified. So
opencode-serve-migration-plan.md saying "Nothing here is implemented" is false.
This is the clearest consolidation candidate in the whole directory: one document recording what was decided and what shipped, replacing nine that describe stages of getting there. I did not do it because it needs reading all nine, and deleting documents unread is not a thing to do at 4am.
The mobile-dav thread — three documents, one conversation
mobile-dav-provisioning · -feedback · -reply. A correspondence. Almost certainly one document.
Unclassified — I have not looked
design-language-interface · file-sync · jobs-unification · mobile-photo-sync-api ·
nextcloud-replacement · agent-git-identity
The plugin split, which affects most of the above
A core install is six processes. Everything else is a plugin, switched off tonight but present on disk. Most documents here were written when the estate was twenty processes and every one of them was simply "there", so they describe availability that no longer holds.
The useful rewrite is usually one line, not a rewrite: say whether the thing described is core or a plugin, and if a plugin, that it is not mounted on a fresh install.
