Only CLAUDE.md conflicted: master restructured it into the short-rule +
docs/architecture-invariants.md pointer layout while this PR was open.
The response-viewer detail now lives in architecture-invariants, so the
Claude turn-grouping and restored-placeholder rebind notes moved there.
Changeset rewritten to record the measured effect on real transcripts.
Both picker endpoints are a second file-serving surface, and they
inherited neither the attachment guard's confinement nor its ownership
scoping. Two separate holes:
1. `sessionId` contributes that session's workingDir as a browse root,
but it was resolved straight off ctx.sessions/ctx.store with no owner
check, unlike the nine other session-scoped handlers in this file. A
non-admin could pin ANOTHER user's working directory as a root just
by passing their session id, then list and preview underneath it. Now
runs canAccessOwned and reports 404, which also avoids confirming
that a session id exists.
2. `Home` and `CASES_DIR` were unconditional roots for every caller.
Per-user spaces live at <USER_SPACES_DIR>/<username>, which is INSIDE
homedir(), so the Home root alone exposed every other user's
workspace. A multi-user non-admin now gets only their own
userSpacePath plus anything explicitly listed in
CODEMAN_FILE_PICKER_ROOTS. /mnt/d is dropped as well: a broad host
mount should be an explicit operator decision in a multi-user
deployment, and operators who want it can name it in that env var.
Admins and single-user mode keep the host-wide roots, so behavior is
unchanged unless CODEMAN_MULTIUSER is on (opt-in, off by default).
All three discriminating tests were verified to fail against the
previous code: browse and preview both returned 200 instead of 404, and
the roots came back as [Home, Codeman Cases, ...] instead of [My Space].
Full suite green, 3784 passed.

Only CLAUDE.md conflicted: master restructured it into the short-rule +
docs/architecture-invariants.md pointer layout while this PR was open.
Route counts reconciled against master's numbering (files 14 -> 16 for
the two new filesystem endpoints, total ~197 -> ~199) and the path
picker's detail moved into architecture-invariants under its own
section.
Adds a "Web / URL" section to the Run dropdown. A saved URL renders as a tab in
the same strip as Claude/Codex/Gemini sessions, with the same Alt+1..9 numbering,
so Codeman is one mission control instead of Codeman plus a pile of browser tabs.
A webview is NOT a sixth SessionMode: no PTY, no tmux, no respawn, no idle
detection. It is a separate resource sharing only the tab strip and the main
content area, the same call that keeps Docker and remote-SSH as case overlays.
Dashboards are proxied through Codeman's own origin, because a direct iframe
fails three ways at once in the shipped deployment: prod serves HTTPS behind
tailscale serve, so http:// targets are hard-blocked as mixed content (with no
override at all on iOS Safari); Grafana/Portainer-class dashboards send
X-Frame-Options: DENY; and our own default-src 'self' CSP blocks cross-origin
frames. Proxying dissolves all three and leaves the production CSP byte-for-byte
unchanged, since /webview/... is already covered by 'self'. A useful side effect:
the fetch happens server-side, so a tailnet-only dashboard is reachable from a
phone that is not on the tailnet.
The proxy is not an API surface. It authenticates on a 192-bit capability in the
path (memory-only, rolling TTL, bound to the minting user, revoked on edit or
delete) and is correspondingly exempt from the cookie and Origin checks, because
a sandboxed iframe is opaque-origin: it sends no SameSite=lax cookie and its
writes arrive with Origin: null. The Host allowlist is never bypassed. A second
Referer-keyed form of the exemption exists for root-absolute assets and is fenced
to safe methods on non-/api, non-/ws, non-/q paths.
Iframes omit allow-same-origin unless a URL is explicitly marked trusted, since a
proxied page is served from Codeman's own origin and could otherwise read this
document and drive the agent-spawning API. Authorization and codeman_session are
stripped upstream in BOTH modes, so CODEMAN_PASSWORD cannot leak into a dashboard.
Two things only a real browser reveals, both presenting as the dashboard's own
"Failed to fetch" while the page itself renders fine:
- Runtime-built root-absolute URLs (fetch('/api/data')) escape <base href> and
land on Codeman's root. Widening the Referer fallback into /api would trade
security for it, so an injected shim patches fetch/XHR/WebSocket/EventSource
inside the frame instead, removing the class rather than the guard.
- An opaque-origin document CORS-checks every request, including to the host it
was served from. Script/css/img loads are not CORS-checked, which is why the
page renders while its API calls die. The proxy now emits CORS headers and
answers preflights itself. registerSecurityHeaders answered every OPTIONS with
a bare 204 before routing, carrying no ACAO for Origin: null, so that
short-circuit now exempts a valid capability.
Neither is reproducible with curl, which does not enforce CORS.
Also fixes a pre-existing bug found on the way: .toolbar has backdrop-filter,
making it a stacking context that trapped .run-mode-menu's z-index:1000, so
.welcome-overlay painted over the whole Run menu. With no session open, every
item in it (Claude Code included) was unclickable.
Verified end to end against a real tailnet dashboard: live data, WebSocket push,
no failed requests, and switching tabs does not reload the frame. 98 new tests
cover the pure rewrite helpers, the CORS helper, the shim's rewrite logic, route
CRUD, and every edge of the auth exemption.

CLAUDE.md was 110KB (~27.5k tokens) loaded into every session, with 30 lines
carrying 49% of the bytes as single-paragraph walls (the Docker cases entry
alone was 9,388 chars). Extract the implementation detail verbatim into
docs/architecture-invariants.md (41 sections) and leave the rule plus a
pointer inline. Result: 59.5KB, ~14.9k tokens, 46% smaller.
Also:
- Add CLAUDE.md to .prettierignore. Prettier's markdown printer escapes
underscores in the glob-heavy paths used throughout, which had already
corrupted the Ultracode paragraph (agent-*.jsonl became agent-\_.jsonl,
collapsing backtick spans). npm run format:check is unaffected; its globs
are src/** only.
- Move version archaeology (PR numbers, ticket ids, commit shas, "was X now
Y" lineage) into the invariants doc, keeping the rules and their reasoning
inline.
- De-duplicate the Core Files table against Key Patterns.
- Document install.sh in Scripts, and why Prettier's scope is deliberately
narrow (14 hand-formatted public JS modules are guarded by
check:public-assets and check:frontend-syntax instead).
Two factual fixes found while verifying: displayKeys is a client-side merge
policy, not a wire filter, and showResponseViewer / showPlanUsageLimits /
language are declared in SettingsUpdateSchema and do persist server-side; and
the respawn route count is 7, not 18.
Verified: 30/30 cross-doc pointers resolve, 1,184 of 1,190 backticked
identifiers from the original survive (the 6 others are dropped archaeology
or the prettier-corrupted spellings), 59 table rows well-formed,
format:check and check:frontend-syntax clean.
