Clicking a .md in the Files panel showed wrapped source with an Edit
pencil and no way to see it rendered, although marked + DOMPurify were
already on the page for the Response Viewer. The viewer now renders
.md/.markdown through that same pipeline (one parser, one click
delegate) with an MD pill back to source, and the plain-text view gains
Lines (CSS-counter gutter) and Wrap toggles. All three persist per device
in their own localStorage keys.
- Relative images are rebased onto the workspace-confined file-raw route
under the document's directory, built inside a <template> so no fetch
fires before the rewrite; a failed load degrades to alt text. Relative
links become a.rv-path so the existing delegate opens them in the
viewer; fragment and http(s) links are untouched.
- The rendered container carries data-i18n-skip so the translator does
not rewrite the document's prose.
- Markdown fetches the route's 10000-line ceiling; other text keeps 500.
- avif renders inline (file-content image set, file-raw MIME map), and
avif/ico printed paths open the viewer instead of tailing bytes. .md
deliberately stays with the tail viewer for printed paths.
Follow-up to #421 (remote-case file reads over ssh), addressing the review.
Symlink escape on a host without `readlink -f` (blocker). The probe's
portable fallback canonicalized only the directory chain and returned the
final component unresolved, so on macOS < 12.3 `ws/notes.txt -> ~/.ssh/id_rsa`
came back as `.../ws/notes.txt` (with the target's size), passed every
containment and blocklist check that runs on `realPath`, and `cat` followed
the link. The fallback now walks the directory chain with `cd -P`/`pwd -P`
and follows the LAST component with plain `readlink` for a bounded number of
hops, and anything it cannot fully resolve (a loop, a readlink failure, the
hop cap) is reported with an `x` marker that parses as null, i.e. 404. It
never returns the unresolved string. Measured on a real /bin/sh with
`readlink -f` shadowed: the pre-fix script reports `/ws/notes.txt`, the fixed
one `/secret/id_rsa`; both branches (native and fallback) now agree.
`PUT /api/sessions/:id/file-content` never had the remote guard the PR
described. It sits ahead of `validateSessionFilePath`, which resolves against
the LOCAL filesystem, because with a same-named directory on the Codeman host
(an sshfs mount of the remote tree, the documented stop-gap) the write landed
on the local twin while the viewer believed it edited the remote file.
ssh fan-out is bounded. `src/remote-ssh-limiter.ts` is a
document-conversion-limiter-shaped semaphore (default 4, env
`CODEMAN_MAX_REMOTE_FILE_SSH`) around every probe and buffered read; the
attachment-history list resolves its whole history in ONE batched probe
(`probeRemoteAttachmentHistory`, threaded into
`registerExternalAttachment({remoteProbes})` so the guards run unchanged)
instead of one handshake per entry; and probes chunk at 40 paths because the
whole script is one argv string. Terminal output in a remote session is
written on the remote host, so a prompt-injected agent printing hundreds of
`codeman://attach` links forked one ssh per link, each holding a 20 s
timeout, and a 100-entry history re-listed on every attachment:detected
tripped OpenSSH's default MaxStartups. Streams are deliberately not counted
(one per browser request, held for a whole playback, and gated behind a
counted probe anyway).
Smaller items from the same review: probe records are NUL-terminated and
index-keyed after a leading NUL (a newline in a filename can no longer shift
the alignment, and the banner is fenced off without last-N-lines guessing);
size comes from `stat -c %s || stat -f %z`; the three IO functions refuse
under VITEST instead of opening a connection; an unreachable host now reads
as unknown (missing: false) for detected AND external history entries, where
external used to fold its 502 into missing; a client that aborted during the
guard probe has its body's ssh child reaped (`reply.raw.destroyed` is checked
before the close listener is attached); `describeExecError` never returns
Node's `Command failed: <ssh line>` message, which carried the identity path
and the probe script into a 502 body; and the docs note that
`isSensitivePath`'s three home-anchored entries resolve against the Codeman
host's home, not the remote one.
Tests: the probe script runs on a real /bin/sh with a `readlink` shim that
rejects `-f` (the escape, a relative chain through a symlinked directory, a
loop, a newline filename, banner chatter that itself looks like a record),
the limiter's cap and FIFO order, and route tests for the PUT guard (local
twin untouched, no connection), the single batched history probe, the
unreachable-host alignment and the aborted-client reap. All four route tests
fail against the pre-fix file-routes.ts.

A clicked path that points OUTSIDE the case directory goes through the attachment
routes (the frontend's `_isExternalPreviewPath` sends every absolute path not under
`workingDir` to `POST /attachments`), and those had the same local-`fs` assumption
as file-raw: `realpathSync`/`fs.stat` on a path that only exists on the remote host,
so the file never opened — the case the #415 report was actually about.
- `registerExternalAttachment()` accepts `remote` and resolves through
`remoteProbePaths` (canonical path, size/mtime, kind, plus the workspace root for
the confinement check). Everything around it — blocklist, extension allowlist,
workspace confinement, registry/dedupe — is now shared by both branches, so the
remote path cannot drift from the local one.
- The by-id routes (`raw`, `preview`, `thumbnail`), the metadata poll and the
attachment history list resolve over ssh too. `raw` streams with the same
Range contract as file-raw; `preview` (office) and `thumbnail` answer 400 for a
remote record; an unreachable host answers 502, a vanished file 404.
- Which host a record is read from follows the SESSION, never the path string: the
same absolute path is a different file on each host, and a remote session never
falls back to a local file with that name.
- Codex generated artifacts keep force-workspace confinement for a remote case: the
well-known artifact directories are anchored at THIS host's home, so only a file
inside the remote workspace is trusted.
Still local-only by design: writes, office conversion, thumbnails, the file
tree/picker and tail-file.
A remote case's workingDir is an absolute path on the remote host, but the
file read routes resolved it with local `fs`: `validateSessionFilePath`'s
realpathSync fails for a path that does not exist on the Codeman host, so
every preview of an agent-written file answered "File not found" (#415).
Add src/remote-files.ts as the single remote-read layer, built on the same
buildSshConnectionArgs() the launch uses:
- remoteProbePaths(): ONE round trip returning realpath + stat for the
requested path AND the workspace root, so containment is checked against a
remotely canonicalized root (a symlinked remotePath is ordinary).
- remoteCreateReadStream(): streams the body (cat, or tail -c +N | head -c L
for a Range) with nothing buffered in memory, and reaps the ssh child when
the response ends so an aborted download cannot orphan it.
- remoteReadFile(): bounded read for file-content.
file-raw, file-content, file-preview and file-thumbnail now share one local/
remote target resolution. Guards keep their local strength: lexical pre-check,
remote realpath, workspace containment, sensitive-path blocklist, and the size
cap applied to the remote size before any bytes are read. An unreachable host
answers 502 with the remote reason instead of a misleading 404. Nothing is ever
copied to the Codeman host and there is NO local fallback (an sshfs mount of
the same tree must not shadow the remote bytes).
Deliberately unchanged: writes (edit=1 / PUT now answer 400 explicitly while
the viewer hides its Edit affordance), office previews, thumbnails, file tree,
picker, external attachment registration and tail-file stay local-only.
The picker's current-folder line was a read-only breadcrumb, so reaching a
deep folder meant tapping through every level, and the listing was fixed to
name order, so the file an agent had just written was somewhere in a
500-entry list.
The current folder is now an editable field: Enter or Go jumps there, a full
file path lands in its folder with that file selected, and a path that does
not resolve keeps the listing you had and says so, instead of the reset to
the root that a stale initialPath gets. A Sort control orders the listing by
name or modified time in either direction, folders always first, and the
choice is remembered per device like the hidden toggle. Each entry shows a
compact modified time (time of day today, month-day this year, else the
date).
GET /api/filesystem/browse stamps every entry with mtimeMs to make that
possible; the stat that already fetched a file's size now serves both, so
it is still one stat per entry. Entries without an mtime (an older server,
the in-container listing) sort after dated ones and then by name.

The 50MB cap on file-raw, the attachment /raw route and /api/download was
memory protection for a `readFile()` that no longer exists: file-raw and
/raw were rewritten to stream through `sendFileBody()` and answer Range
requests, so size costs a read stream rather than RSS (measured: a 600MB
download moved peak RSS by ~37MB). All the cap still did was refuse
legitimate downloads of build artifacts, videos and archives.
It is now MAX_FILE_DOWNLOAD_BYTES in config/buffer-limits.ts, default 2GB,
env CODEMAN_MAX_DOWNLOAD_BYTES, 0 = unlimited. `parseByteLimitEnv()` is
separate from the `parseInt(...) || default` idiom used elsewhere in that
file precisely because that idiom reads 0 as falsy and would silently
restore the default for the one value that means "no limit".
/api/download was the last route that really did buffer the whole file. It
now shares sendFileBody() with the other two, so it streams, advertises
Accept-Ranges, and is resumable. Its Content-Disposition also goes through
buildContentDisposition() rather than raw interpolation.
Refusals move from 400 to 413 across all three, which is the correct status
for the case; with the cap at 2GB it is a path almost nothing reaches now.

The two merge-time edits the #383 review asked for. The comment above the
picker's fallback chain said Home is nested under Codeman Cases; on the
native default it is the other way round (~/codeman-cases sits inside ~).
And the "Filesystem path picker" paragraph in architecture-invariants still
said the picker falls back to /mnt/d, which #383 changed to: the session's
Current Folder, then the Codeman Cases root, then /mnt/d, then the first
root. No code behaviour changes.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The "Link Existing" case picker opens with an empty path and no
sessionId, so the browse endpoint's fallback root picked whichever
root happened to be first in the list — which was always `Home`.
On the native default that's harmless (~/codeman-cases nests inside
Home anyway), but a Docker deployment binds CODEMAN_APPDATA_PATH
(Home) and CODEMAN_CASES_PATH at unrelated host paths, so the picker
opened somewhere with no cases in sight. Worse: if CODEMAN_CASES_PATH
is ever changed after cases already exist, the old cases directory
lingers, still reachable, under Home — indistinguishable at a glance
from the real one under the new Codeman Cases root.
Prefer the Codeman Cases root in the fallback chain, ahead of the
generic roots[0].

Link Existing's Browse did nothing: GET /api/filesystem/browse answered 403
"No filesystem browse roots are available".
Two rules were fighting. /root is a default blocked tree in the attachment
guard, and Codeman running as root — containers, plenty of servers — makes
homedir() exactly /root, so the picker's own allowlisted Home root was blocked;
the other candidates live under it or do not exist. The root list came out
empty and there was nothing the user could open.
The blocked trees exist to keep ~/.ssh and friends out of reach, not to seal off
the user's own home. Only trees that would swallow a configured root whole are
dropped now: /root goes when Home is it (or sits inside it), /etc holds no
configured root and is untouched. Secrets stay protected — isSensitivePath
independently matches .ssh/, .env and credentials* at any depth, and it is what
the directory probe asks about.
⚠️ Navigation must reuse the same narrowed list the roots were chosen with.
Handing the raw trees downstream admits a root and then refuses every path
inside it, which reads as a picker that opens and does nothing.
GET /api/sessions/:id/files gains an optional `q`. With one, the endpoint
answers a FLAT match list instead of a nested tree; without one, the response is
exactly what it was, so every existing caller is untouched.
compileFileQuery() (src/utils/file-query.ts) turns the query string into a
reusable predicate, so the walk prunes as it goes rather than streaming the
whole tree to the client to be filtered there. An empty or whitespace-only
query compiles to null, which is what makes "no query" and "blank query" the
same thing.
The search walk deliberately recurses past directories that do not match — a
file whose ancestors don't match is exactly what people are searching for — so
it carries its own maxMatches cap on top of the existing maxFiles and maxDepth
ones, and reports `truncated` when it stops early. Hidden-file and
excluded-directory rules are the same ones tree mode already applies.
Tests: file-query.test.ts covers the matcher; routes/file-search-mode.test.ts
drives the endpoint against a real temp tree and pins the two properties worth
having — that the walk reaches a match under non-matching parents, and that an
absent or whitespace query leaves the tree response alone. Gating the recursion
on a match turns those red.
A .json/.log/.yaml/code path outside the session workspace was refused as an
unsupported type, and clicking one in the terminal made it worse: text goes to
the log viewer, which spawns `tail -f` and allows only the workspace, /var/log
and ~/logs, so it answered "Path must be within working directory or allowed
log directories" while the same path clicked in the response viewer previewed
fine. Two surfaces, two answers, for a file the session can already cat.
- TEXT_ATTACHMENT_EXTENSIONS IS EDITABLE_EXTENSIONS (config/file-editing.ts),
not a second curated list that would drift from it. The rule reads: if the
viewer would open a file for editing inside the workspace, the same file
outside it can be read. The suffix was never the confidentiality gate here,
the path guard is (sensitive-file blocklist, /root and /etc trees, realpath
before the check), and it still runs on every registration.
- Widening what can be READ must not widen what can RUN. html/htm join svg in
serveRawFile's download-only branch, so markup is never served with a
renderable type on our own origin; other text goes out as inert
text/plain; charset=utf-8 with nosniff, matching what the path picker does.
The preview reads through fetch(), which ignores the disposition, so a
clicked .html still shows its source.
- ~/.codeman*/state.json joins isSensitivePath. It persists
SessionState.envOverrides and the env allowlist admits key-shaped names
(GEMINI_API_KEY, CLAUDE_CODE_*), so it can hold a live credential. Same
treatment as hook-secret and users.json, and the rest of the tree stays
attachable.
- The terminal sends an out-of-workspace path to the preview instead of the log
viewer. In-workspace text keeps the tail viewer, which is the point of it, and
file-stream-manager's allowlist is untouched: no `tail -f` on arbitrary host
paths.
- The by-id text preview is bounded like the workspace one: a Range request for
the first 512KB (a real partial read, not a discarded 50MB download) plus a
500-line cap, with the footer saying so.
Verified on an isolated instance: a 1.1MB external log opens in ~1.8s showing
500 lines with "showing first 500 lines" in the footer; json, yaml and code
preview; an .html carrying a script tag renders as source and does not execute;
.svg is still refused; a terminal click on an external .yaml opens the preview
with no log viewer and no attachment card; an in-workspace .log still opens the
streaming tail viewer.

A clip an agent wrote inside the workspace played with a working scrub bar,
while the same file in /tmp was refused as an unsupported type. The workspace
preview classified media with its own inline extension sets and the attachment
allowlist had no media at all, so the two paths disagreed about what a video is.
- VIDEO_ATTACHMENT_EXTENSIONS and AUDIO_ATTACHMENT_EXTENSIONS now live in
attachment-registry.ts and are imported by file-content's classification, so
both paths answer the same. mp4/webm/mov/m4v/ogv and
mp3/wav/ogg/oga/m4a/aac/flac/opus join the attachment allowlist.
- Real MIME types for those extensions. Without one the raw route falls back to
application/octet-stream, which a <video> refuses to decode: the player
renders and then does nothing.
- getAttachmentType() gained the video and audio members of
AttachmentDetectedType. Attachment cards have no per-type CSS and their
thumbnail falls back to the type label, since the thumbnailer has no media
branch and answers 204 rather than spawning a converter.
- The preview overlay's by-id branch renders <video>/<audio> with the same
markup as the workspace branch, playsinline included. Serving was already
range-aware, so seeking works.
The image-watcher keeps its own narrow detection list (png/pdf/docx/pptx), so
this does not start popping cards for every video an agent writes. Text types
that are not md or txt (.json, .log, code files) remain out of the allowlist by
choice and still report what is previewable instead.
Verified on an isolated instance: an external mp4 and mp3 both play, seek, and
report the right duration, matching the in-workspace clip exactly, and a click
on an external mp4 in the terminal opens the player with no attachment card.

A path an agent prints was already underlined in the terminal, but clicking
one opened the preview overlay on "File not found": file-content/file-raw
resolve against the session workingDir and refuse anything outside it, and the
paths agents print most (a /tmp capture, Claude's own scratchpad, another
checkout) are outside it by definition. In the response viewer those paths were
not links at all.
- openFilePreview() detects an out-of-workspace path and registers it through
POST /api/sessions/:id/attachments first, rendering by attachment id. That is
the surface built for live external files, so the server-side guard is
unchanged: secret trees blocked, symlinks resolved, extension allowlist. The
workspace routes keep refusing escapes exactly as before.
- New optional `notify` field on that route. `notify: false` suppresses only the
attachment:detected broadcast, so a click does not also pop a card announcing
the file already filling the screen. Default stays true for the CLI and
publish callers.
- _linkifyFilePaths() links paths in rendered response-viewer markdown. It walks
text nodes and builds anchors with DOM APIs (the source is model output; never
a string rebuild of sanitized markup), skips subtrees already inside an <a>,
and keeps the message text byte-identical so copy-code is unaffected.
- One path pattern in constants.js now feeds both the xterm link provider and
the chat linkifier, a fresh instance per call since lastIndex is per-object
state. It picks up /Users and /mnt roots (nothing was clickable on macOS or
WSL), plus docx/pptx and video/audio extensions.
- .file-preview-overlay moves to z-index 5100, above the response viewer at
5000. At its old 2000 a path clicked in the chat opened the overlay behind the
panel it was launched from.
Verified end to end on an isolated instance, desktop and phone viewport: real
clicks in the terminal and the chat both render the image, external md and pdf
render, /etc/hosts is still refused, workspace previews unchanged.

Two bugs in the File Viewer's media player, both reproduced in a real
browser against an 18MB mp4 before and after the fix.
1. Closing the preview left the video playing. closeFilePreview() only
dropped the overlay's `visible` class, which is display:none and
nothing else, so the audio kept going with no visible player to pause.
Detaching the element is not a fix either: a detached HTMLMediaElement
plays on until it is garbage collected. _stopFilePreviewMedia() now
pauses, drops src and load()s every media element (also on re-open,
where overwriting innerHTML had the same effect), which additionally
aborts the in-flight download.
2. The scrub bar was inert. file-raw read the whole file and answered
200 with no Accept-Ranges, so Chrome reported video.seekable as
[0, 0] and silently reverted `currentTime = x`; Safari refuses to
start such media at all. Raw bodies are now streamed and range-aware:
Accept-Ranges: bytes on every response, 206 + Content-Range for a
Range request, 416 for one past EOF, and a malformed spec ignored
(200) per RFC 9110. Parsing is pure in src/web/http-range.ts.
Measured on tmp/codeman-crt-v5-66s.mp4 (18MB, 66.6s):
before seekable [0, 0] seek to 56.6s reverted to 3.9s close: still playing
after seekable [0, 66.56] seek to 56.6s landed at 60.2s close: paused, NETWORK_EMPTY
Range slices are byte-identical to `dd`, the full-file path is
byte-identical to the file, and the SVG octet-stream/attachment
hardening and the 50MB cap are unchanged (the cap is still checked
before the range).

The picker behind Link Existing's "Browse" and the mobile keyboard's Path key
refused every path with a dot-prefixed segment, so `.github/workflows/ci.yml`
could not be selected and a hidden folder could not be opened at all. It gains
the same `.*` toggle as the File Viewer: default OFF, per-device, and applied to
both the listing and the preview endpoint, which re-resolves the path
independently.
That dotfile filter was quietly doing security work. The picker's roots include
Home, so with every hidden path unreachable the shared blocklist never had to
name the credentials that live in dot-directories. Lifting the filter removes
that accident, so `isSensitivePath` now covers them explicitly: SSH keys at any
depth rather than only under $HOME, GPG keyrings, AWS/GCloud/Azure/Docker/
Kubernetes credentials, npm, Yarn, git, gh, netrc, PyPI, RubyGems, Cargo and
Terraform tokens, .pgpass and .my.cnf, and the Claude and Codeman agent
credentials. `~/.codeman/` and `~/.claude/` stay attachable as trees, since the
publish skill and the review-card loop read from them; only their secret-bearing
members are named.
Everything else still applies with the toggle on: blocked trees, sensitive
files, root confinement, ownership scoping and symlink-escape checks. A hidden
entry whose realpath is a secret is dropped from the listing, and opening it is
refused.
Follows #221
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`reply.raw.writeHead()` writes straight to the Node response and bypasses
Fastify's header store, so everything the `onRequest` security hook granted is
silently dropped on every route that answers that way.
The visible symptom is CORS. The hook emits `Access-Control-Allow-Origin` for
localhost origins, so a page served from a local dev server may call every `/api`
endpoint cross-origin — except the four below, whose requests fail. The security
headers (`X-Content-Type-Options`, `X-Frame-Options`, CSP) were being lost the
same way.
Affected: `GET /api/events`, and `file-raw` / `tail-file` / `download` in
file-routes.ts. Each now spreads the inherited headers first and lets its own
headers win over them.
Tests drive a real WebServer and compare `/api/events` against `/api/status` for
the same Origin — the point of the fix being that the SSE route stops being the
odd one out. Verified in both directions: with the fix removed, 3 of the 5 fail.

Closes#212. The file-preview overlay can now edit workspace text files in
place, phone-first: agent writes a file, you review it in the viewer, tweak
two lines, save, tell the agent to continue.
Backend (file-routes.ts, policy in src/config/file-editing.ts):
- GET file-content?edit=1: read-for-edit that never truncates (a truncated
buffer must never become an edit buffer), 512KB cap (413 over it), and
returns the sha256 hash + detected EOL the client echoes back on save.
- PUT /api/sessions/:id/file-content: edit-in-place only, with no O_CREAT
anywhere in the handler. Confinement matches the read path (realpath +
workspace boundary + ownership via findSessionOrFail), plus sensitive-path
and attachment-guard blocklists, a .git subtree deny, and an extension
allowlist (svg and env deliberately excluded). Optimistic concurrency via
baseHash: mismatch is a 409 unless force. Writes are wx-temp + fchmod +
fsync + rename, closing the validate-then-write TOCTOU window.
- Corruption guards: NUL sniff + UTF-8 round-trip compare (refuses binary
and latin-1), and server-side EOL re-application so a textarea's LF
normalization cannot rewrite every line of a CRLF file.
- Plain reads gain an additive editable flag the UI keys the button off.
Frontend (panels-ui.js + overlay markup/styles):
- Edit button on editable text previews; textarea editor with Save/Cancel,
dirty indicator, discard-confirm on cancel/close, and a conflict dialog
that offers overwrite (force) when the file changed on disk mid-edit.
- Phone: full-bleed window sized by --app-height so the editor and Save bar
track the OS keyboard; 16px editor font (iOS zoom guard); no autofocus.
- zh-CN strings for the new chrome.
Tests: pure policy unit tests plus a route suite that deliberately does NOT
mock node:fs. It runs against a real temp workspace so symlink escapes,
write-through of in-workspace symlinks, mode preservation, CRLF round-trip,
409/force, and the no-create property are exercised for real. Also verified
end to end on an isolated beta instance: 39-check curl matrix, Playwright
desktop flow (real clicks and typing, bytes asserted on disk, live conflict
with an external rewrite), and a 393px phone profile.

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.

Scopes real-time streams and the init snapshot so a multi-user client only
receives what it owns. No-op in single-user mode (identity-less clients).
- WS terminal (ws-routes): owner gate after the session lookup. A non-admin may
only attach to their own session (close 4003); the global auth hook already
ran on the upgrade and decorated req.authUser, so an unauthenticated upgrade
never reaches the handler.
- SSE (sse-stream-manager): per-client identity stored at addClient; broadcast()
and the terminal-batch flush both enforce a routing hint via canDeliver().
WebServer.broadcast auto-derives the hint (deriveSseHint): session-scoped event
families resolve the owner from the payload's session id (fail closed when the
owner can't be resolved), machine-level families (docker/tunnel/update/system/
cron) + host-plan telemetry are admin-only, everything else stays global. Raw
terminal bytes resolve the owner once and are withheld from non-owners.
- getLightState is filtered per connection AFTER the shared cache (sessions,
respawnStatus, subagents, workflowRuns by owner; scheduledRuns + planUsage
admin-only); applied to both the SSE init snapshot and GET /api/status.
- file-routes: getKnownSessionWorkingDir + getSessionAttachmentHistory (the
preview/thumbnail/history helpers that bypass findSessionOrFail) now owner-check
the session, closing a cross-user file-read path.
- GET /api/search: harvestSources is owner-scoped.
Deferred to a follow-up (documented in docs/multi-user-plan.md): away-digest +
subagent/workflow REST list scoping, push-subscription identity + routing,
per-user screenshot subdirs. The live-event versions of these are already routed
by the SSE hint; only the on-demand REST aggregates remain global for admins-only
follow-up.

Threads per-user ownership through sessions, cases, cron, and the permission
policy. All scoping is a no-op in single-user mode (isMultiUserMode() guards).
Sessions
- Session.owner stamped at every create path from req.authUser / job.owner:
POST /api/sessions, /api/run, /api/quick-start, ralph start, cron launch,
plan generation. Round-trips through recovery (MuxSession.owner mirror, read
muxSession.owner ?? savedState?.owner) and the mux layer.
- findSessionOrFail(ctx, id, req) now does a NOT_FOUND owner check (never 403, so
other users' session existence is not leaked); wired at ~50 call sites.
- List endpoints filtered by owner: GET /api/sessions, /api/sessions/unified
(live+persisted+lifecycle scoped, host-wide transcripts admin-only), cron jobs.
Permission policy (section 6.3)
- resolveClaudeModeForUsername wraps getClaudeModeConfig at every spawn site so a
non-granted user is forced to --permission-mode auto (bypass -> auto), including
recovery (or a reboot would un-downgrade). buildPromptArgs now respects the
session's claudeMode, closing the one-shot (runPrompt) bypass hole.
- Shell mode and cron launchCommand require canBypassPermissions: 403 at
POST /api/sessions, /api/quick-start create, cron job create, AND cron fire time
(re-checked against the owner's current grant).
Cases
- resolveCasesDir(user): per-user ~/codeman-users/<name>/cases in multi-user, the
shared ~/codeman-cases otherwise. All case CRUD + ralph + plan + quick-start
resolve through it. resolveCasePath is owner-aware.
- GET /api/cases scoped per user (own folders; legacy linked cases admin-only;
remote/docker cases owner-filtered). RemoteCase/DockerCase gain owner, stamped
at link/quickcreate/import.
- Remote + Docker host CRUD is admin-only.
- Non-admin workingDir confinement (the linchpin): realpath must resolve inside the
user's space, enforced at POST /api/sessions and /api/run BEFORE any disk write.
Limits
- sessionCapacityState / sessionCapacityMessage centralize the global + per-user
cap (CODEMAN_MAX_SESSIONS_PER_USER, default global/2), replacing the 6 copy-pasted
MAX_CONCURRENT_SESSIONS checks.
Tests: test/ownership-scoping.test.ts (case isolation, host-CRUD gate, workingDir +
shell gates, and the scoping helpers). Deferred to phase 4: WS owner gate, SSE
fan-out filtering, file-route preview/thumbnail helper scoping, push routing.

The File Browser preview and Attachments preview share openFilePreview(),
but the workspace branch (via /file-content) misclassified several types the
attachments viewer handled fine:
- SVG was reported as type:image, but file-raw serves SVG as octet-stream +
attachment (XSS hardening), so the <img> broke. Now fetched and rendered via
a same-origin image/svg+xml blob <img> (safe; <img> never runs SVG scripts).
file-raw's SVG hardening is unchanged.
- Audio (mp3/wav/ogg/m4a/aac/flac/opus) was type:binary -> "Cannot preview".
Now classified as audio and rendered with <audio controls>; file-raw gained
the matching audio/video MIME types so playback works.
- Binary formats not in the hardcoded list (xlsx/doc/zip/...) were decoded as
UTF-8 and dumped as mojibake. Replaced the static list with a NUL-byte
content sniff that flags arbitrary binaries; the binary fallback now offers a
Download link instead of dead-ending.
Adds route tests for audio, known-binary (xlsx), and NUL-sniff classification.
Verified end-to-end on an isolated instance + headless browser.

Follow-up fixes applied during review of PR #121 (all confirmed minor/nit;
no blockers). Security posture verified sound (externalPath never leaves
toState()/the list route; re-registration runs the guard).
- fix(recovery): restoreAttachmentHistory now skips malformed/legacy saved
items (null, non-object, missing source/fileName) instead of throwing inside
the Session constructor — a corrupt __attachmentHistory entry could otherwise
abort the entire mux-recovery loop. (P1)
- fix(routes): the attachment-list route degrades a single failing entry to
{missing:true} instead of failing the whole drawer. (INT-4)
- fix(ui): give the attachments header button a positioning context so the
unread badge anchors to the icon, not the header bar. (F1/CSS-1)
- fix(ui): cancel the debounced history refresh on drawer close and guard it
against a stale session/closed drawer. (F3)
- fix(ui): re-show ("Card") of a detected item now uses the item's own
timestamp so the cardId is stable — focuses the existing card instead of
stacking duplicates. (F4)
- fix(ui): Escape now closes the drawer, matching every other panel. (UX-1)
- fix(ui): badge shows "99+" past 99 (was an inconsistent 100/99 cap). (BADGE-1)
- style: drop the duplicate @keyframes notif-badge-pulse (dead CSS). (INT-1/CSS-3)
- style: empty-state used three undefined CSS custom properties
(--text-primary/--border-color/--bg-tertiary) → use the defined
--text/--border-light/--bg-input tokens. (CSS-2)
- test: add constructor restore round-trip + malformed-item resilience tests.
Deferred (noted for author): broadcasting the full 100-item history in every
session-state SSE event (payload bloat), "unread" badge semantics, making the
header button opt-in, and app.inject route tests for the two new endpoints.

Stacks on COD-38: accumulates a per-session attachment history and exposes it
through a slide-in drawer with an unread badge, so attachments stay reachable
after their cards are dismissed.
Backend:
- session-attachment-history: history state — dedupe by source path / relative
path, newest-first, 100-item cap, and externalPath sanitization (the absolute
host path is server-private and never leaves toState()).
- session.ts: _attachmentHistory + getter (sanitized) / upsert / restore /
getAttachmentHistoryForPersist; restored from saved state in the constructor.
- file-routes: GET /attachments (list — resolves each entry to live metadata +
routes; external entries are re-registered) and GET /attachments/:id
(metadata poll). The by-id route guards via the registry's TOCTOU-safe
resolveServableAttachmentPath.
- server.ts: detected/registered attachments upsert into history and persist;
the private (externalPath-bearing) history rides on disk under
__attachmentHistory, separate from the sanitized public copy, and is restored
on mux-session recovery.
- types/session.ts: SessionAttachmentHistoryItem + SessionState.attachmentHistory.
Frontend:
- panels-ui: the drawer (lazy-built), unread badge, list render with per-item
preview/download/open/"Card" (reshow) actions, and live refresh of the open
drawer on new detections.
- app.js: history state + per-session badge/cleanup wiring.
- index.html / styles.css / mobile.css: header button + badge and the drawer.
Verified: tsc / eslint / prettier / frontend-syntax / public-assets clean; new
history-module unit tests pass; full test:ci green (2866 passed); badge, drawer
open/render/reshow/close verified in-browser.
Builds on the COD-37 registry: surfaces detected/registered attachments as
dismissible cards with a first-page thumbnail and an inline preview — the
consumer the registry PR deliberately deferred.
Backend:
- document-thumbnailer: first-page PNG thumbnails (PNG passthrough; PDF via
pdftoppm; Office via the preview cache).
- document-preview-cache: disk-cached DOCX/PPTX -> PDF conversion (LibreOffice
/ PowerShell COM), in-flight dedup, multi-converter fallback.
- file-routes: serveConvertedPreview / serveThumbnail + four routes —
GET .../attachments/:id/preview, .../thumbnail and the workspace-path
file-preview / file-thumbnail. Reuses the registry's TOCTOU-safe
resolveServableAttachmentPath, so previews stream the freshly-resolved path.
- server: enrich detected attachment events with a thumbnail route.
- image-watcher: .png now routes to attachment:detected — this PR adds the card
consumer, so the screenshot popup is no longer its only handler.
Frontend:
- panels-ui: attachment cards (addAttachmentCard, lazy stack, Clear-all,
per-session cleanup) plus a 3-arg openFilePreview that renders registered
attachments inline (image/PDF) or via the server-converted PDF (docx/pptx).
- app.js: wire attachment:detected -> _onAttachmentDetected and card state.
- styles: attachment-card + stack styling.
Verified: tsc / eslint / prettier / frontend-syntax clean; new thumbnailer +
preview-cache unit tests pass; full test:ci green (2861 passed); card render +
preview overlay + dismiss verified in-browser.
Security (MAJOR): the terminal-output codeman://attach scanner registered any
matching path server-side with no user confirmation and broadcast the rawUrl
over SSE. Terminal output is attacker-influenceable (a prompt-injected session
can print an arbitrary path), so on the default no-auth deployment this was an
arbitrary host-file (png/pdf/docx/pptx/md/txt) read primitive reachable by any
SSE client. Magic-link registration is now force-confined to the session
workspace (forceWorkspaceConfinement) regardless of the global confine setting;
deliberate cross-workspace attach still works through the explicit,
Origin-guarded POST /attachments route and 'codeman attach' (which POSTs
directly inside a managed session). Documented in security-architecture.md.
Regression (MAJOR): .png was rerouted from the image-popup path to
attachment:detected, which has no frontend consumer — silently breaking the
dropped/pasted-screenshot popup. PNG stays on image:detected; only pdf/docx/pptx
(which never had a popup) emit attachment:detected.
Also:
- raw route streams the freshly-resolved path, not the stored one, so a
post-registration symlink swap can't redirect the stream (TOCTOU).
- 50MB cap on the attachment raw route, matching file-raw / download.
- per-session attachment registry cap (200) to bound the POST path.
- CLI reads creds via dataPath('.env'), honoring CODEMAN_INSTANCE.
Tests: forced-confinement reject/allow cases; PNG popup-path assertions updated.
Adds the foundation for serving local files to the browser as live external
attachments with a stable id, so requests never carry arbitrary absolute paths.
- attachment-registry: in-memory, session-scoped registry. registerExternalAttachment
validates an absolute path, resolves symlinks, enforces the path guard, and mints
an `att_<uuid>` id; records are cleared when the session is removed.
- attachment path guard: a configurable blocklist (secret locations + /root,/etc
trees, extendable via attachmentBlockedPaths / CODEMAN_ATTACHMENT_BLOCKED_PATHS)
plus an optional, default-off workspace-confinement mode. Shares one
sensitive-path blocklist (web/sensitive-path.ts) with /api/download, which is
refactored to use the extracted module instead of an inline copy.
- terminal magic links: the session scans output for codeman://attach?path=... and
emits `attachmentRequested`; the web server registers the file and broadcasts an
`attachment:detected` SSE event. `codeman attach <path>` (CLI) prints the magic
link or POSTs directly when a session id is known.
- image watcher: detects png/pdf/docx/pptx dropped into a session's working dir and
emits `attachment:detected`.
- routes: POST /api/sessions/:id/attachments (register) and
GET /api/sessions/:id/attachments/:attachmentId/raw (serve), both re-checking the
guard before streaming.
Document previews/thumbnails and the attachment-history drawer build on this
foundation and land separately.
Verified: tsc --noEmit, lint, format, frontend-syntax, full test:ci (2846 passed),
and a server boot smoke (/api/status 200).
A 15-agent audit of the merged tree confirmed 9 envelope/contract bugs;
all fixed here, with live-server contract tests added:
Blockers (fresh-install quick start broken):
- session-ui.js runClaude/runShell unwrapped .data from the /api/cases/:name
404 error envelope (which has no data key), so a not-yet-created case threw
TypeError instead of triggering the auto-create fallback. Now '?.data ?? {}'.
Contract violations on the new stable surface:
- Unknown /api routes returned HTTP 404 with {success:true,...} (Fastify's
default not-found payload was wrapped by the envelope hook). Added a
setNotFoundHandler returning the standard error envelope for /api paths.
- POST /api/events/subscribe 400 body became {success:true,data:{error}};
now createErrorResponse(INVALID_INPUT).
- POST /api/clipboard validation error lacked errorCode and shipped HTTP 200;
now createErrorResponse(INVALID_INPUT) -> 400.
- POST /api/run catch path returned bare {success:false,sessionId,error}
(HTTP 200, no errorCode); now OPERATION_FAILED envelope -> 422 with the
dead session id in the message.
- DELETE tail-file/:streamId returned {success: closed}, colliding with the
envelope discriminator; now returns {closed}.
Dead/regressed UI paths:
- Plan history modal could never open: route returned the bare history array
under data while the frontend read data.data.history/currentVersion. Route
now returns {history, currentVersion}; modal task count fixed to stats.total.
- Self-update error toast read j.error.message from the string-typed envelope
error, always falling back to the generic message; now reads the string.
Cleanup:
- Removed the stale QuickStartResponse type (unreferenced; documented the
pre-envelope shape and invited success-key collisions).
Tests: new test/http-contract.test.ts boots a real WebServer (port 3168) and
pins the envelope, /api/v1 alias, error statuses, and the /api 404 shape —
the route-test harness does not install the server-level hook, so these need
the live server. Updated file-routes/plan-routes/scheduled-runs tests to the
fixed shapes.

Split 6,710-line server.ts into focused route modules using port
interfaces for dependency injection. 107/109 routes extracted into
12 domain files with auth middleware, 5 port interfaces, and shared
helpers. Server.ts retains orchestration (SSE, lifecycle, state).
