The tunnel Upload URL page (upload.html) has been broken since the response envelope landed in 458fb81c: it reads j.filename and j.files while the server answers { success, data: { filename } } and { success, data: { files } }, so every upload reported "Saved: undefined" and the recent list stayed empty. Nothing else reads ~/.codeman/screenshots/, and handing a file to an agent goes through POST /api/sessions/:id/paste-image into the session's own workspace, so the page, its Settings row, the suffix branch of the tunnel row helper (now folded into its one caller) and the Upload URL i18n key go.
The three /api/screenshots routes keep working unchanged and log one deprecation warning per process on first use, naming paste-image as the replacement. Per docs/versioning-policy.md they are removed in a later MAJOR, after at least one MINOR release that carries the warning; the docs, CLAUDE.md and the multi-user plan say so.
Static caching: with upload.html gone no HTML is served by @fastify/static any more (every page has its own no-cache route; on a built tree only the precompressed index.html.gz artifact is reachable, as application/gzip, and nothing requests it). The .html branch of setHeaders was therefore dead and goes with the test that fetched upload.html to reach it; a comment now says a new static HTML page needs its own route. The index.html no-cache assertion on the route stays.
The opt-in multi-user feature's only enforcement is web-layer scoping
(all sessions share one OS account). An adversarial review found 8 critical
+ 7 high cross-user holes that defeated it, plus mediums; all fixed here.
Single-user (flag-off) behavior stays byte-identical apart from documented
consistency deltas.
Ownership / confinement:
- DELETE /api/sessions (bulk) + /:id now owner-scope / findSessionOrFail
- quick-start, cron (create+fire), scheduled runs confine workingDir to the
owner's space; case link/docker-link/docker-import confine the host path
- resolveCasePath no longer resolves linked cases for non-admins; foreign
remote/docker cases are skipped (fall through to the caller's own local case)
- history, subagents/workflows, mux-sessions, orchestrator, cron run-history,
away-digest, and remote/docker host reads are owner- or admin-scoped
Permission policy (section 6.3):
- non-granted users are downgraded at every spawn site incl. legacy
/api/scheduled, PlanOrchestrator one-shots, remote launch, and the cron-fire
gemini/codex bypass switches; resolveClaudeModeForUsername now fails closed
Auth / store:
- verify-first login throttle (a correct password is never locked out),
/ws terminal subject to the change-password lockbox, cookie fast-path
re-validates identity live, role/grant changes revoke sessions, admin delete
runs the last-admin guard before any teardown
- users.json: distinguish missing (ENOENT) from corrupt/unreadable so a bad
read can't overwrite all accounts; unique per-process temp write path
Event streams:
- debounced session:updated + batched task:updated, clipboard, and push
notifications route by owner (fail closed); getLightState hides machine-wide
globalStats from non-admins
Tests: two suites updated to assert the fixed (secure) behavior. tsc, eslint,
and test:ci all green.

Stamp the plan doc with shipped-by-phase status; add the multi-user Key Patterns
entry + State Files + case-spaces note to CLAUDE.md; add a multi-user section to
the security architecture (threat model: workspace separation, not a security
boundary) and a README opt-in section; add a minor changeset.

Design plan for opt-in multi-user support (per-user case spaces, admin
panel, ownership scoping). Ported onto master as the base for the
feat/multiuser-mode implementation branch.
