The UI is a full control plane: it can create tasks, release or complete
them, and inject approval keystrokes into live panes. authz.HTTP did cover
it (an absent surface header defaults to Web), but the gate is opt-in and
the deployed env sets no tokens while binding all interfaces, so in
practice it was reachable unauthenticated from the LAN. Setting the token
alone did not work either: a browser cannot put a bearer token on a
document load, so the UI would 401 on index.html.
- ORCHESTRA_WEB_TOKEN is now mandatory; startup fails rather than silently
serving an open control plane.
- authz.Sessions issues random values stored SHA-256-hashed, with a TTL,
so a leaked snapshot yields nothing usable.
- POST /v1/ui/session verifies the token in constant time and returns it
as an HttpOnly, SameSite=Strict, Secure cookie. This is a presentable
form of the same credential, not a new authority.
- HTTPWithSessions accepts that cookie in place of the bearer token, and
only for the Web surface. The login endpoint and non-/v1/ GETs (the SPA
shell) are exempt by necessity; every /v1/ control path stays gated.
Note this is a breaking config change: .orchestra-config/orchestra.env
sets no tokens, so the service will not start until it does, and setting a
Web token newly gates the other /v1/ surfaces that default to Web.
AUDIT.md is reconciled against the code rather than against itself. B14,
B15 and B16 are closed with their evidence; B17 is closed on the worker
path only; the stale claim that B13 was open is corrected. Adds the
previously undocumented command channel and web UI, and files what that
implementation pass surfaced: federated approvals emit no event (B19), the
local capture revision is a timestamp rather than a change counter and can
silently defeat approvals (B20), the command queue never prunes (B21), the
ntfy token serves two unrelated purposes (S12), and a dead copy of the
authorization policy sits in main.go (S13).
