images and videos get a thumbnail in grid and list. one <Thumbnail>, two sizes — two implementations would have drifted the first time one learned something the other did not, and the fallback is the part that would have drifted. FFMPEG FOR BOTH, and no new dependency. a video needs a frame extracted, which only ffmpeg does; an image only needs resizing, which sharp does faster and with better format coverage. sharp is nevertheless not used: it sits in node_modules as somebody else's transitive dependency and is absent from package.json, so importing it is an undeclared dependency — the thing the frozen lockfile exists to prevent — and declaring it is a deliberate --no-frozen-lockfile that belongs to whoever owns the dependency list. ffmpeg is already a hard requirement of this router, so this adds nothing to what the machine must have. the cost is HEIC and a few exotics, which fall back to the icon. THE CACHE KEY CONTAINS MTIME AND SIZE. a path alone would be wrong: replace a photo under the same name and every screen keeps the old picture with nothing to clear it but somebody who knows the cache exists. keyed on content, a changed file is a different key — the old entry is orphaned rather than stale, and the response can be `immutable` honestly rather than as a bet. FAILURES ARE REMEMBERED. the browser retries a broken <img> every time it re-enters the viewport, so without this one corrupt video runs ffmpeg on every scroll, forever. in memory, so a restart gives it another chance after somebody installs a codec. `ls` DECIDES what can be thumbnailed, not the client. the browser's own NATIVE_VIDEO_EXTS is deliberately only what a <video> tag can play, which is a different question from what ffmpeg can take a frame out of — every .mkv would have gone without a picture for that reason alone. the entry has just been stat'd, so the answer is a lookup on its name. FOUND WHILE TESTING, and the reason there is a test folder: ffmpeg EXITS 0 HAVING WRITTEN A ZERO-BYTE FILE when the seek lands past the end of the input. a 0.4s clip gave exit 0 and 0 bytes with `-ss 1`, and exit 0 and a real JPEG without it. the retry keyed on the exit code and so never fired, reporting every short video as having no thumbnail. it keys on the output file now — there is one question worth asking an image encoder and it is whether there is an image. four ffmpeg at a time. the grid is virtualised so only what is on screen is asked for, but scrolling fast through a folder of video queues far more than is visible, and unbounded decoding turned a 1.9GB box into a swap storm once already. size is snapped to 64px steps so a panel resizing by a pixel cannot mint a hundred entries of one image. verified: 240 and 256 share a cache entry, 200 gets its own.

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.
