pastilhas 4c24df93c1 a chat can change model mid-conversation
the selector locked on `hasStarted`, so the tier was fixed for the life of a conversation. nothing
justified it — the commit that added the flag says only "default model" — and the hazard it resembles is
narrower than what it blocked: crossing HARNESS hands an opencode `ses_…` id to `claude --resume`, which
reads as a dead agent rather than a wrong dispatch. changing TIER was always safe.

so tier is free, harness is pinned, and the server refuses a crossing rather than relying on the UI to.

the claude side does it the way the CLI's /model does: `Query.setModel()`, a control request that needs
streaming input mode, which is the only mode this file uses. nothing is torn down and nothing is
re-resumed — cwd, permission mode and transcript all continue and only the next response changes. an
earlier plan here was to kill the session and re-create it with the stored resume id; that would have
worked and was unnecessary.

opencode already switched per turn (serve-runner POSTs the model to the live session), so only the UI was
in its way.

FIXES A SILENT MISMATCH while it is here. model reached the SDK once, in createSession's query() options,
and every later turn was pushed onto that same call — so a changed model was dropped while session:init,
the cost fold and the durable log all reported the new tier. reachable today by leaving a chat idle past
the 30-minute GC: the UI said sonnet, opus answered, nothing logged it. the fold now tracks what the
harness actually did rather than what the client asked for, and a refused switch reverts the picker.

the switch is a durable `model:switched` event and a centred marker in the transcript, because the useful
question is the BOUNDARY — which half of this conversation is opus. per-message model was already stamped
server-side and shown nowhere, and claude-sessions.ts reads the FIRST model in a transcript, so a switch
was invisible in history.

tests: turn-stream proves the marker is durable and lands after the previous model's last words; the
selector tests pull in opposite directions, so unlocking everything fails one and restoring the blanket
lock fails the other. verified by re-breaking both.

not done: opencode's `steer` path (a send mid-turn) returns before the model POST, so a switch there
applies on the next full turn. session.model also stays stale for opencode tier changes — harness routing
is unaffected.

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 from full − light. Those files are gone, and catalogue.test.ts was 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_KEY is now the per-purpose wallet key.
  • push-notifications.md — "agreed design, 2026-07-31". Notify is a plugin and unmounted.
  • chat-session-lifetime.md, chat-ui-walkthrough.md — reference officer-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.

  • sidecar-audit-2026-07.md (1,377 lines)
  • claude-sidecar-isolation.md — records the officer-claude → officer-agent rename that preceded tonight's officer-agent → officer-claude-code
  • open-threads-after-per-user-claude.md
  • two-agent-field-report-2026-08-12.md
  • api-method-changes-2026-08-06.md

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.
