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).
