Committing work that was left uncommitted in the shared tree. I did not write it;
I reviewed it in full, verified it against the running system, and am landing it at
the owner's explicit request because no one currently owns it.
This REPAIRS master. `useAgentPanel.ts` shipped in dbe585f and calls
`/chat/agent-panels`, but `registerAgentPanelRoutes` existed only in the working
tree — so on master as pushed, every one of those calls 404s. The feature has been
half-landed since that commit.
What it is. A panel on a dashboard can be given a name ("frontend", "code-reviewer").
Naming it mints two things: a `sessionKey`, which is the panel's permanent continuity
(it keys the sidecar's on-disk resume map and `chat_session_events`, so the same panel
reopens the same Claude session), and a `handoffToken`, a bearer credential scoped to
exactly one verb. The agent in that panel is then addressable by name, and can pass
work to a peer on the same dashboard over `/api/agent-handoff`.
Three doors, deliberately separate:
- `/chat/agent-panels` (browser, session-authed) — name / list / rename / forget.
Mounted on the chat router rather than given its own prefix: these routes create
and name Claude sessions, which is authority `chat` already grants. A second
top-level mount would have meant a second capability entry claiming the same
thing under a different name.
- `/api/agent-handoff` (agent, token-authed) — peers and send. Unprotected by the
session middleware and exempted in `capabilities/totality.ts` with its reasoning
written down, because the caller is a subprocess with a token, not a browser with
a cookie.
- The transcript stays where transcripts live. DELETE forgets the address and the
panel's claim on the session; it does not touch ~/.claude/projects.
Security, as verified rather than assumed:
- The sender is derived from the token, never from the request body — there is no
`from` field on the wire, so it cannot be forged.
- Every lookup is scoped to the token's `userId` AND `dashboardId`, so an agent can
only see and reach peers on its own dashboard.
- `toAgentPanelView` strips `handoffToken` and `userId`, and it is the only shape
the browser routes return. Confirmed by reading every return path.
- Live-tested: a real token on `GET /api/agent-handoff/peers` returns 200 with
correctly scoped peers; a bogus one returns 401.
Two judgement calls in the code worth knowing about, both already commented at their
site: the introduction turn inlines the handoff token into a runnable curl (a
single-owner MVP trade), and `agent_panels` carries no FK to `dashboards.id` because
that primary key is mid-rework to a composite.
Schema uses `uniqueIndex` throughout, never `unique().on(...)` — the rule that exists
because drizzle-kit mis-diffs named composite unique constraints and re-creates them,
which is what wiped seven tables on 2026-08-03.
NO `bun db:push` IS NEEDED. `agent_panels` is already live in Postgres with 6 rows;
the schema file is catching up to a database that already has it.
Verified: `bunx tsgo` clean, `bun test` 538 pass / 0 fail across 35 files.
