## Bug
`/org/import` had no per-tenant mutex, advisory lock, or DB-level
uniqueness on (parent_id, name). The pattern was lookup-then-insert:
existingID, existing, err := h.lookupExistingChild(...) // SELECT
if existing { return /* skip */ }
db.DB.ExecContext(ctx, `INSERT INTO workspaces ...`) // INSERT
Two concurrent admin POSTs (rapid double-click in canvas, retry-after-
timeout, two operators on the same template) both saw "not found" in
the SELECT and both INSERT'd the same (parent_id, name).
Captured impact: tenant-hongming accumulated 72 stale child workspaces
in 4 days from repeated org-template spawns of the same template
(see #2857 phase 4 sweeper for the cleanup; #2872 for the prevention RFC).
## Fix
Two-layer fix — DB-level backstop AND application-level happy path:
1. **Migration** `20260506000000_workspaces_unique_parent_name.up.sql`
```sql
CREATE UNIQUE INDEX CONCURRENTLY IF NOT EXISTS workspaces_parent_name_uniq
ON workspaces (
COALESCE(parent_id, '00000000-0000-0000-0000-000000000000'::uuid),
name
)
WHERE status != 'removed';
```
* COALESCE(parent_id, sentinel) collapses NULLs so root workspaces
also collide pairwise.
* `WHERE status != 'removed'` lets a tombstoned row be replaced
by a same-named re-import (preserves existing org-import semantics).
* CONCURRENTLY avoids ACCESS EXCLUSIVE on production tenants under
live traffic; IF NOT EXISTS makes the migration resumable.
* Down migration drops CONCURRENTLY symmetrically.
2. **`org_import.go` swap**
Replace lookup-then-insert with `INSERT ... ON CONFLICT DO NOTHING
RETURNING id`. On the skip path (RETURNING returns 0 rows →
sql.ErrNoRows), re-select the existing id to recurse children:
INSERT INTO workspaces (...) VALUES (...)
ON CONFLICT (COALESCE(parent_id, ...), name)
WHERE status != 'removed'
DO NOTHING
RETURNING id;
The ON CONFLICT target predicate matches the partial-index predicate
exactly — required for Postgres to consider the index applicable.
Existing `lookupExistingChild` helper kept (still used on the skip
path); semantics unchanged.
## Test coverage
* AST gate refreshed to assert the workspaces INSERT contains the
ON CONFLICT pattern (`onConflictDoNothingRE`) instead of the now-obsolete
"lookup-before-insert" ordering. Per behavior-based gating
(memory: feedback_behavior_based_ast_gates.md), the new gate pins
the actual TOCTOU-resolution behavior.
* Companion `TestGate_FailsWhenInsertOmitsOnConflict` proves the gate
catches the bug shape on synthetic source.
* All existing `lookupExistingChild` unit tests (no-rows, found,
nil-parent, DB error, wrapped no-rows) still pass — helper is
unchanged and still load-bearing on the skip path.
* Live Postgres E2E coverage runs via the existing
"Handlers Postgres Integration" CI job, which applies migrations
to a real PG and exercises the INSERT path.
## Why ship the migration + swap together (not stacked)
The migration alone provides a DB-level backstop, but without the
handler swap a UNIQUE-violation surfaces as a 500 to the user. The
handler swap alone has no enforceable target until the migration
applies. Shipped together they give graceful skip + atomic backstop.
Migration is CONCURRENTLY + IF NOT EXISTS, safe to apply even on
tenants where the sweeper (#2860) hasn't run yet — the index just
declines to build until conflicting rows are reconciled.

Closes#149.
uploadPollMode for poll-mode chat uploads previously committed N
pending_uploads rows in one Tx (PutBatch), then wrote N activity_logs
rows individually outside any Tx. A per-row failure on activity row K
left rows 1..K-1 committed and pending_uploads orphaned until the 24h
TTL — not data-loss because the platform's fetcher handled the
half-state cleanly, but the user never saw file K in the canvas and
the inconsistency surfaced as an "uploaded but invisible" complaint
class.
Thread one Tx through PutBatchTx + N × LogActivityTx + Commit so all
or none commit. Broadcasts are deferred until after Commit — emitting
an ACTIVITY_LOGGED event for a row that ends up rolled back would
paint a ghost message into the canvas's optimistic UI. A new
LogActivityTx returns a commitHook the caller invokes post-Commit;
the existing fire-and-forget LogActivity is unchanged for the 4 other
production callers (a2a_proxy_helpers + activity.go report path).
Storage interface gains PutBatchTx; PostgresStorage.PutBatch is
refactored to share the validation + insert path. inMemStorage and
fakeSweepStorage delegate or no-op for PutBatchTx (the in-mem fake
can't model Tx state — DB-level atomicity is verified by the existing
real-Postgres integration test for PutBatch + the new unit test
asserting the Go handler calls Rollback on activity-insert failure).
Tests:
- TestPollUpload_AtomicRollbackOnActivityInsertFailure pins the new
contract via sqlmock — second activity insert errors → Rollback
expected, Commit must NOT be called.
- TestLogActivityTx_DefersBroadcastUntilCommitHook +
_InsertError_NoHook_NoBroadcast + _NilTx_Errors cover the new API.
- TestPutBatchTx_HappyPath / _EmptyItems / _ValidationFails /
_PerRowErrorPropagates cover Tx-aware storage layer.
- 7 existing TestPollUpload_* tests updated to mock Begin + Commit
(or Begin + Rollback for failure paths) since the handler now
opens a Tx around PutBatch + activity inserts.
All workspace-server tests pass; integration tag also clean.

User asked for VSCode-style drag-drop upload (#2999): "drag local to
upload to target folder just like vscode does". Today the only upload
path is the toolbar's Upload button (folder picker). Drag-drop lets
users grab files from Finder/Explorer and drop them directly on a
specific subdirectory in the tree.
1. New `uploadDataTransferItems(items, targetDir)` in `useFilesApi`
— walks the HTML5 DataTransferItemList via `webkitGetAsEntry()`,
recursing folders to a flat (relativePath, file) list, then PUTs
each via the existing /files/<path> endpoint. The walker (also
exported via `__testables`) calls `readEntries()` in a loop until
empty so multi-batch folders (browsers cap each call at ~100
entries) aren't silently truncated.
2. `uploadFiles` (folder-picker path) gained an optional `targetDir`
parameter. Same prefixing semantics so future surfaces (e.g. an
"upload here" toolbar button on a row) can reuse it.
3. `FileTree` directory rows gained `onDragOver` / `onDragEnter` /
`onDragLeave` / `onDrop` handlers + a hover-target highlight
(accent-tinted background + outline). dragLeave uses
`currentTarget.contains(relatedTarget)` to suppress the flicker
that fires when the cursor crosses any child of the row (icon,
label, ✕ button) — without this the highlight strobes on every
sub-element transition.
4. `FilesTab` wraps the tree column in an outer drop zone for
"drop on root" — drops outside any specific subdir row land at
root. The empty-state placeholder copy now includes a
"drag files here to upload" hint when the active root is
/configs (the only writable root today).
5. Both the row drop and the root drop are gated on
`root === "/configs"` (the same gate that already blocks the
toolbar's New / Upload / Clear). Other roots ignore the drag
entirely (no highlight, no drop), so the user doesn't get a
misleading drag affordance followed by a "switch root" toast.
`dragDropUpload.test.tsx` (9 tests, two layers):
Walker tests (pure function, no DOM):
- `walkEntry` collects a single dropped file with correct relpath.
- `walkEntry` walks a folder + preserves folder name in the path.
- **Multi-batch loop**: a fake reader that emits two batches of 2
+ an empty terminator must yield 4 files. A walker that called
readEntries once would see only 2 — this is the load-bearing
assertion against silent folder truncation.
- Nested directories: outer/inner/file.md → "outer/inner/file.md".
FileTree drag-drop wiring (DOM):
- `dragover` on a directory row preventDefault's (load-bearing —
without it the drop event never fires).
- `drop` on a directory row fires `onDropToTarget(path, items)`.
- `drop` on a FILE row does NOT fire (only directories are valid
drop targets).
- `drop` with no DataTransferItems does NOT fire (defensive guard
against text-only drags).
- `dragenter` adds the highlight class to the directory row.
1. The 1MB per-file size cap is inherited from the existing
`uploadFiles`. A user dropping a 5MB skill bundle silently
skips the file (the loop's `continue` on `file.size >
1_000_000`). Same behavior as the toolbar Upload, so consistent
if not great. Surfacing skipped-files would be a UX improvement
tracked separately — not load-bearing for this PR.
2. Drop-zone highlight on the column wrapper uses an outline that
sits inside the column's overflow-y-auto scroll container. If
the user drags onto a row that's mid-scroll, the highlight may
clip slightly at the scroll boundary. Cosmetic only; the drop
still works.
3. The `?root=` query is NOT passed on the underlying writeFile
call (matches the existing uploadFiles behavior). On a backend
without #2999 PR-A, this means uploads always land in /configs
regardless of selected root — but we already gated drop on
`root === "/configs"` so the practical effect is nil today.
Once PR-A merges and the canvas threads ?root= through writes
(separate follow-up), drops on /home etc. would be enableable
by lifting the canDelete-style gate.
- `npx tsc --noEmit` clean
- 177/177 canvas tab tests pass
- Manual on local dev: drag a file from Finder onto /configs/skills
row → file appears under /configs/skills/<name>. Drag a folder of
3 files onto root area → 3 files uploaded with folder structure
preserved. Drag onto /home tree → no highlight, no drop.
Refs #2999. Pairs with PR-A (backend EIC) — without PR-A the tree
is empty on SaaS and there's nothing to drop ONTO; PR-D still works
on self-hosted today.

Adds two new arms to the AttachmentPreview kind dispatcher:
* PDF — chip in the bubble, click opens the shared AttachmentLightbox
with a browser-native <embed type="application/pdf"> at 95vw/90vh.
Fetch+Blob+ObjectURL auth path matches AttachmentImage / Video. PDF.js
not pulled in; browser viewer is good enough for the desktop chat MVP
(Slack/Linear/Notion all gate full-page PDF behind a click for the
same reason). Falls back to AttachmentChip on fetch error.
* Text/code/JSON/YAML — first 10 lines in monospace <pre><code> right
in the bubble, "Show all N lines" expands to full content, with a
filename + ⬇ download header. Streams up to 256 KB then marks
truncated and offers a download chip; large logs don't crash the
bubble. No syntax highlighting in v1 — shiki adds 200-500 KB and is
pure polish.
Coverage: 5 new dispatch tests (PDF success → embed in lightbox,
PDF fetch fail → chip fallback, text inline render, text long content

## Why
User asked for a VSCode-style right-click menu on file rows (#2999):
"right click to have a menu to download". Today the only download
affordance is the toolbar's Export-all (bulk JSON dump), and the
inline ✕ button is the only delete UX (small click target, easy to
miss).
## Fix
1. New `FileTreeContextMenu` component — fixed-position popover with
Open / Download / Delete items composed per-row (files get all
three; directories get Delete only since "open a directory in the
editor" doesn't apply). Esc + outside-click + Tab + scroll
dismiss. ↓/↑ arrow keys rove focus between menu items. role=menu
+ role=menuitem + autofocus on first item for a11y.
2. Menu state lifted to the top-level `FileTree` (not per-row) so
opening a second row's menu auto-closes the first — only one
menu open at a time, matching VSCode/Theia. Pinned by the
`replaces the first` test.
3. New `downloadFileByPath(path)` in `useFilesApi` — fetches via the
existing GET /workspaces/<id>/files/<path>?root= endpoint and
triggers a browser download. Distinct from the existing
`handleDownloadFile` which downloads the in-editor buffer
(round-trips unsaved edits to disk); the context-menu download
targets arbitrary tree rows the user hasn't opened.
4. `canDelete` prop threaded from FilesTab → FileTree → menu →
item. Same gate as the toolbar (Clear/New/Upload all gated to
/configs); context menu's Delete renders as disabled with a
muted background on other roots, matching the "feature exists
but isn't applicable here" pattern.
## Test coverage
`FileTreeContextMenu.test.tsx` (8 tests):
- File row → menu opens with Open + Download + Delete.
- Directory row → menu opens with Delete only.
- Click Download → onDownload(path) fires + menu closes.
- Click Delete (canDelete=true) → onDelete(path) fires.
- Click Delete (canDelete=false) → onDelete NOT called + menu stays
open (disabled-state UX).
- Esc dismisses.
- Outside-click (mousedown on document.body) dismisses.
- Opening second context menu replaces the first (only-one-open
invariant).
Each test uses fireEvent + screen.getByRole, so they fail on a
deleted-code regression — none would pass on the pre-PR shape.
## Three weakest spots (hostile self-review)
1. The menu is positioned at `clientX/clientY` without viewport
clamping. If the user right-clicks at the very bottom-right of
the panel, part of the menu may overflow off-screen. VSCode
handles this by flipping the anchor; we don't yet. Acceptable
v1 because the FilesTab is fixed-width (≤ side-panel width)
and the menu is small (140×~80px); the overflow would be a few
pixels of one item. Filed as a follow-up.
2. Auto-focus on the first item shifts keyboard focus away from
the row that opened the menu. Closing with Esc returns focus
to the body, not the row. Same behavior as TerminalTab's
placeholder + the canvas's other context menus; consistent
isn't ideal but at least uniform. Documented inline.
3. The download request reuses the API client's 15s default
timeout — large config files (multi-MB skill bundles) on a
slow connection could time out. Same risk applies to the
existing toolbar Export. If we see real download failures we
can add a `timeoutMs` override at the call site without
touching the menu.
## Verification
- `npx tsc --noEmit` clean
- 176/176 canvas tab tests pass
- Manual on local dev: right-click a config.yaml row → menu opens
→ click Download → file lands in Downloads. Right-click on
/home root → Delete renders disabled.
Refs #2999. Pairs with PR-A (backend EIC) — without PR-A the tree
is empty and there's nothing to right-click on a SaaS workspace.
🤖 Generated with [Claude Code](https://claude.com/claude-code)
## Why
Reported by user (issue #2999): external workspaces (mac laptop, mac
mini, hermes-on-home-server — runtime="external") render the FilesTab
identically to the SaaS empty-listing bug, showing "0 files / No
config files yet" even though the platform doesn't actually own the
filesystem of these workspaces. Visually indistinguishable from the
broken state, reads as a bug.
## Fix
Mirror the affordance TerminalTab adopted in PR #2830 for runtimes
without a TTY:
1. New `NotAvailablePanel` in `canvas/src/components/tabs/FilesTab/`
— folder-with-slash icon + "Files not available" headline + body
text that names the runtime and points the user at Chat.
2. `FilesTab` now takes optional `data?: WorkspaceNodeData`. When
`data.runtime` is in `RUNTIMES_WITHOUT_FILES` (currently just
"external"), early-return the placeholder before mounting the
useFilesApi hook. Mirrors TerminalTab's prop shape exactly so the
review pattern is uniform across tabs.
3. SidePanel passes `node.data` to FilesTab (matches existing pattern
for ChatTab / TerminalTab).
## Test coverage
`FilesTab.notAvailable.test.tsx` (4 tests):
- external runtime → banner renders with runtime name + Chat-tab
guidance copy.
- external runtime → NO `/files` API request fires (asserted by
inspecting the mocked api.get call log).
- claude-code runtime → no banner, normal mount proceeds (toolbar's
root selector is the discriminator).
- data prop omitted → falls through to normal mount (back-compat
with any caller that doesn't thread data through, e.g. legacy
tests).
Each branch is independent and discriminating — none would pass on
a code-deleted version of the early-return.
## Three weakest spots (hostile self-review)
1. `RUNTIMES_WITHOUT_FILES` is a hardcoded set in this file. If a
future runtime joins (e.g. a "byok-claude" that runs on user
hardware), someone has to remember to add it here. Reviewed
alternatives: pull from a runtime-capabilities registry — same
shape as `RUNTIMES_WITHOUT_TERMINAL` already in TerminalTab. We
chose the parallel pattern over a new abstraction; consolidating
into a shared registry can land if/when a third tab grows the
same gate (rule of three). Documented inline.
2. The placeholder is a static panel — no retry, no "report bug"
link. Same as TerminalTab's. Acceptable because the absence is
intentional, not transient.
3. Chat-tab guidance is hardcoded English. No i18n in canvas yet;
matches the rest of the codebase. Will move with the i18n
migration when that lands.
## Verification
- `npx tsc --noEmit` clean
- 54/54 canvas tab + SidePanel tests pass
- Will be live-verified on staging post-merge: open Files tab on an
external workspace (mac laptop) → expect placeholder; open on a
platform-owned workspace (Hongming Personal Brand Agent) → expect
normal tree (assuming PR-A also lands).
Refs #2999. Pairs with PR-A (backend EIC fix) — without PR-A the
platform-owned path still shows "0 files" because the backend never
returns rows.

## User-visible bug
Canvas Files tab returns "0 files / No config files yet" for every
SaaS workspace, every root (/configs, /home, /workspace, /plugins).
Reported by user (canvas screenshot, hongming.moleculesai.app,
Hongming Personal Brand Agent — claude-code, T4, online).
## Root cause
`ListFiles` (templates.go) was missing the SSH-via-EIC branch that
ReadFile (PR #2785) and WriteFile (PR #1702) already have. On SaaS,
dockerCli is nil → findContainer returns "" → falls through to
host-side resolveTemplateDir which only matches baked-in template
names. For a user-named workspace it matches nothing, so the handler
silently returns []fileEntry{}.
DeleteFile had the same gap — right-click delete (introduced in PR-C
of this issue) would silently no-op once #1 was fixed.
## Fix
1. Extracted shared EIC plumbing into `withEICTunnel` (closure-based,
single SSOT for keypair → key push → tunnel → port-wait → cleanup).
Refactored writeFileViaEIC + readFileViaEIC to use it. Added
listFilesViaEIC + deleteFileViaEIC on the same scaffold. The
`LogLevel=ERROR` shim from PR #2822 now lives in one
`eicSSHSession.sshArgs()` helper instead of being duplicated per
helper — the next time we need to tweak ssh options, one place.
2. Factored remote shell strings into pure functions
(buildInstallShell / buildCatShell / buildRmShell / buildFindShell
+ parseFindOutput) so the wire shape can be pinned without booting
a real EIC tunnel.
3. Refactored `resolveWorkspaceFilePath(runtime, root, relPath)` to
honor `?root=`. New rule: `/configs` (or empty / unrecognized) →
runtime managed-config dir via workspaceFilePathPrefix (preserves
the v1 ReadFile/WriteFile behaviour where canvas's Config tab
GETs/PUTs config.yaml without specifying a root and lands in the
right per-runtime dir); `/home`, `/workspace`, `/plugins` →
literal absolute path on the EC2 host. List/Read/Write/Delete now
agree on what file a tree row points to — pre-fix List would say
"/home contents" but Read/Write would route to /configs.
4. ListFiles + DeleteFile dispatch on instance_id != "" → EIC helper.
Errors from the EIC path produce 500 (not silent fall-through to
local-Docker, which would mask the failure as "0 files" — the
exact user-visible symptom).
5. Added ?root= validation gate to WriteFile + DeleteFile so an
out-of-allowlist root is rejected before the resolver runs.
## Test coverage
- TestResolveWorkspaceFilePath_RuntimeIndirection — pins the
/configs → runtime prefix translation per-runtime (hermes,
claude-code, langgraph, external, unknown). Catches the regression
where a future edit accidentally drops the runtime indirection.
- TestResolveWorkspaceFilePath_LiteralRoots — pins /home,
/workspace, /plugins as literal pass-through regardless of
runtime. Catches the symmetric regression where the literal roots
start getting rewritten to the runtime prefix (which would mean
the FilesTab "/home" selector silently routes to /configs on
hermes).
- TestResolveWorkspaceRootPath — directory-only translation used
by listFilesViaEIC, same indirection rules.
- TestSSHArgs_HardenedFlags — pins the centralised ssh option set
(LogLevel=ERROR + hardening). Catches drift in the
one-place-where-ssh-flags-live.
- TestEicSSHSessionSingleSourceForSSHFlags — behaviour-based AST
gate (per memory). Counts s.sshArgs() callers (must be ≥4 —
list/read/write/delete) and asserts LogLevel=ERROR appears
exactly once in the source. Fires if anyone copy-pastes a raw
ssh args slice instead of going through the helper.
- TestBuildInstallShell / TestBuildCatShell / TestBuildRmShell /
TestBuildFindShell — pure-function tests pinning the remote
command shape. Catches regression like "rm -f silently becomes
rm -rf" or "find loses node_modules pruning" without needing a
real EC2.
- TestBuildFindShell_DepthForwarding — catches a regression where
the helper hard-codes a depth instead of using the caller's value.
- TestParseFindOutput / TestParseFindOutput_EmptyInput — pin the
TYPE|SIZE|REL parser. Empty-input case explicitly returns []
not nil so the JSON wire shape stays a list.
- TestListFiles_EICDispatch_Success / Error — sqlmock-driven
handler test. Verifies instance_id != "" routes to listFilesViaEIC
and surfaces errors as 500 (does NOT silently fall through to
local-Docker, which is the exact regression-mode of the original
bug).
- TestListFiles_EICBranch_NotTakenForSelfHosted — back-compat
guard: instance_id == "" must NOT enter the EIC branch (would
break self-hosted operators).
- TestDeleteFile_EICDispatch_Success / Error — same shape for
DeleteFile.
- TestListFiles_RootValidation / TestDeleteFile_RootValidation —
?root=/etc must 400 before any DB query or EIC call.
## Verification
- `go build ./...` clean
- `go test ./...` clean (full workspace-server suite)
- Will be live-verified against staging on hongming.moleculesai.app
after merge: open Files tab → expect populated /home + /configs +
/workspace listings (not "0 files"); right-click delete on
/configs/old.yaml → expect file removed on the EC2 host.
## Three weakest spots (hostile self-review)
1. The LogLevel=ERROR drift gate counts source occurrences. A
future refactor that intentionally moves the literal somewhere
else (e.g. into a constant) would trigger a false positive. The
gate's failure message points to the load-bearing constraint
(must appear in sshArgs); operator can adjust.
2. `eicFileWriteTimeout` constant kept as an alias for back-compat
with prior tests. Documented as intentional + safe to remove on
the next pass.
3. The resolver tests pin the runtime → prefix map values
(`/home/ubuntu/.hermes`, `/configs`, etc.). A future runtime
addition that ships a new prefix needs the test updated. This
is intentional — silent prefix changes orphan saved files, so a
test failure on map edit IS the right signal.
## Follow-up (RFC #2312 subtask 2)
Long-term the right fix is to drop EIC entirely and HTTP-forward to
the workspace's own URL (RFC #2312). That's a substantially larger
refactor across 5 surfaces (chat upload, files, templates, plugins,
terminal) and out of scope for this bug-fix PR. Tracked separately
under that RFC.

Second specialized renderer pair landing under RFC #2991. Stacks on
PR-1 (#2997) — extends the AttachmentPreview dispatcher with video/
audio cases.
Why HTML5-native (not custom JS player)
---------------------------------------
- Browser vendors ship hardware-accelerated decoders, captions,
pinch + scrub UX, and fullscreen UI. We get all of it for free.
- Native fullscreen via the <video> control bar — no
AttachmentLightbox needed for video (the browser's built-in
fullscreen handles it).
- Mobile-friendly without us writing the touch handlers.
Auth model
----------
Identical to AttachmentImage (PR-1): platform-auth URIs need our
cookie/token, so we fetch the bytes, wrap in a Blob, hand the
browser an ObjectURL via <video src=> / <audio src=>. External
http(s) URIs skip the fetch.
Memory caveat: a Blob holds the entire media in JS memory until the
bubble unmounts. The server's 25MB single-file cap (chat_files.go)
bounds this; v2 can switch to MediaSource + streaming if larger
files become a real shape.
Failure modes
-------------
- Fetch failure (404, 403, network) → AttachmentChip fallback.
- Bytes that aren't valid media (corrupt, wrong Content-Type) →
<video onError> / <audio onError> swap to chip.
Tests
-----
5 new component tests in AttachmentPreview.test.tsx (now 14 total):
- kind=video → <video controls> with blob URL src
- kind=video fetch fails → falls back to chip
- kind=video extension fallback (no mime) → routes to video path
- kind=audio → <audio controls> + filename label visible
- kind=audio fetch fails → falls back to chip
The preview-kind unit tests from PR-1 (49 cases) already cover the
MIME → video / audio dispatch logic; this PR's component tests pin
the rendered DOM shape (controls attribute, blob URL src, fallback
behavior).
Hostile self-review
-------------------
1. Memory bound: 25MB cap protects us today; documented future
migration path (MediaSource).
2. iOS Safari autoplay: playsInline pinned on <video> so mobile
doesn't auto-fullscreen on play.
3. Captions accessibility: <track kind="captions" /> placeholder so
the element is tagged correctly even though we don't have caption
files yet (forward-compatible).
Verified
- tsc --noEmit clean
- 173 chat tests green (49 unit + 14 component + 110 pre-existing)
Stacks on PR-1 (#2997). PR-3 (PDF + text/code) is the final piece.
Refs RFC #2991, PR #2997 (PR-1).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
First specialized renderer landing under RFC #2991 — chat attachment
preview. Adds the dispatch infrastructure that PR-2 (video/audio) and
PR-3 (PDF/text) will extend.
Architecture (RFC #2991 Phase 2 design)
---------------------------------------
- preview-kind.ts: pure helper that maps mimeType (+ extension fallback
for missing/generic MIME) to one of: image | video | audio | pdf |
text | file. Single source of truth; the dispatch axis for every
attachment renderer.
- AttachmentPreview.tsx: SSOT dispatch component. ChatTab no longer
imports kind-specific components — it imports AttachmentPreview,
which switches on the kind and renders the right child.
- AttachmentImage.tsx: inline thumbnail (max 240×180) + click →
lightbox. Auth-aware: for platform URIs (workspace: /
platform-pending: / etc) the bytes are fetched via JS-injected
headers, wrapped in a Blob, served as ObjectURL — bare <img src>
would not include the cookie/token.
- AttachmentLightbox.tsx: shared fullscreen modal (image now; PDF will
use it in PR-3). Esc / backdrop click / X button to close, focus
trap on close button, focus restoration on close.
- AttachmentChip retained as the kind=file fallback. No breaking
change for existing renderable shapes.
External-workspace coverage
---------------------------
The wire shape (ChatAttachment.mimeType + uri) is identical for
internal + external workspaces — both go through AgentMessageWriter
(PR #2949). External claude-code agents that attach images via
send_message_to_user automatically get the new preview surface; no
runtime-side change needed.
Failure modes
-------------
- Fetch failure (404, 403, network) → AttachmentChip fallback so the
user still gets a working download. Pinned by tests.
- Decoded as non-image (corrupt bytes, wrong Content-Type) → onError
on the <img> swaps to AttachmentChip. Pinned by tests.
- Non-platform URIs (http/https external image hosts) → skip the
auth-fetch flow, use the raw URL via resolveAttachmentHref. Pinned
by extension-fallback tests.
Tests
-----
preview-kind.test.ts (49 cases):
- Strict MIME match across image/video/audio/pdf/text/unknown
- Extension fallback when MIME is missing or application/octet-stream
- URL with query string + fragment → strip before parsing
- MIME wins over extension (regression: don't render image-named zip)
- SVG is image (not text) despite being XML
- Non-canonical MIME like application/javascript → text
AttachmentPreview.test.tsx (9 component tests):
- Dispatch: kind=file → chip, kind=image → image path
- Loading state shows placeholder, NOT chip (proves dispatch routed)
- Extension fallback (no mimeType) routes to image path
- Fetch fail (404) and network error → fall back to chip
- Image success: <img> renders ObjectURL, click opens lightbox
- Lightbox: Esc closes, backdrop click closes, content click doesn't
- Universal fallback: unknown MIME → chip even when extension hints
at a renderable kind
Hostile self-review (3 weakest spots, addressed)
------------------------------------------------
1. <img> auth: bare <img src="/chat/download?..."> would NOT include
our auth headers. Resolved via fetch+Blob+ObjectURL pattern.
Pinned by the image-success test (asserts src === "blob:test-url").
2. Server-side allowed-roots mismatch: pre-fix tests used /tmp/ paths
which the server doesn't allow. Caught when the dispatch test
fell into the non-platform path. Updated tests to use /workspace/
subpaths matching templates.go's allowedRoots.
3. Bundle size creep: each kind component adds bytes. Lightbox is
currently always-bundled. Lazy-loading is plausible but defer
until measured-needed.
Verified
- tsc --noEmit clean
- 168 chat tests green (49 unit + 9 component + 110 pre-existing)
PR-2 (video + audio) and PR-3 (PDF + text) extend the dispatch in
AttachmentPreview.tsx with their own kind-specific components.

The 15-min sweeper has been deleting stale e2e orgs but not the
orphan tunnels left behind when the org-delete cascade half-fails
(CP transient 5xx after the org row is gone but before the CF
tunnel delete completes). Result: tunnels accumulate in CF until
manual operator cleanup.
Add a final step that POSTs `/cp/admin/orphan-tunnels/cleanup`
every tick. Best-effort — failure doesn't fail the workflow; next
tick re-attempts. Output reports deleted_count + failed count for
ops visibility.
This is the catch-all for the orphan-tunnel class. The proper
upstream fix (transactional org delete) lives in CP and tracks as
issue #2989. Until that lands, the sweeper bounded-time-to-cleanup
keeps the leak from escalating.
Note: PR #492 (cf-tunnel silent-success fix) makes this step
actually effective — pre-fix DeleteTunnel silent-succeeded on
1022, so the cleanup endpoint reported success without deleting.
Post-fix the cleanup chains CleanupTunnelConnections + retry on
1022, which actually clears stuck-connector orphans.

PR #2990 root cause: the resolver SQL added `name` to the SELECT for
DisplayName plumbing, but the e2e test's sqlmock fixture
(expectChainQueryRoot at swap_test.go:216) still scripts the
3-column shape. Three e2e tests fail with:
sql: expected 3 destination arguments in Scan, not 4
Fix: bump the fixture to 4 columns (id, name, parent_id, depth) and
pass an empty name. The e2e tests don't assert on label rendering —
they pin the namespace string flow ("workspace:root-1" etc), which
is unchanged. Empty name is fine: ReadableNamespaces still emits the
correct namespace strings; only DisplayName is empty.
Caught by CI's Platform (Go) check on PR #2990 — would have been a
silent missed-coverage case in the resolver_test.go run because that
package doesn't import the e2e package.

User feedback on the v2 Memory tab redesign: on a root workspace, the
namespace dropdown showed three indistinguishable entries:
Workspace (30ba7f0b)
Team (30ba7f0b) (team)
Org (30ba7f0b-b303-4a20-aefe-3a4a675b8aa4) (org)
For a root workspace, the resolver collapses workspace==team==org IDs
(resolver.go:113-122 derive() degenerate case). The previous
shortID(8)-truncated UUID label scheme made all three look identical
even though the three concepts (private / team-shared / org-wide)
remain semantically distinct.
## Backend — Resolver returns DisplayName
- SQL chain query now SELECTs workspaces.name (COALESCE → "" on NULL)
- chainNode carries .name through walk
- deriveNames() computes the display name for each namespace,
mirroring derive():
workspace: self.name
team: parent.name (or self.name if root — degenerate)
org: chain[end].name (root of tree)
- Namespace struct gets a new DisplayName field, omitempty wire-shape
## Backend — Handler renders label from DisplayName when present
- memories_v2.go:namespaceLabelWithName(name, kind, displayName) is
the new SSOT label generator. Falls back to the UUID-prefix shape
when displayName is empty so callers without name plumbing keep
working unchanged.
- namespacesToViews now plumbs Namespace.DisplayName into the label.
- Old namespaceLabel(name, kind) is preserved as a thin wrapper
around namespaceLabelWithName(_, _, "") for back-compat.
- Custom namespaces ignore displayName by design — operator-defined
suffixes ARE the chosen label; a name override would surprise.
## Frontend — drop redundant `(kind)` suffix
Pre-fix: "Team (mac laptop) (team)" — kind shown twice.
Post-fix: "Team (mac laptop)" — the prefix already conveys the kind.
## Test coverage
Resolver (3 new tests):
- DisplayName_Root: workspace name propagates to all 3 namespaces
- DisplayName_Child: workspace=self.name, team=parent.name, org=root.name
- DisplayName_EmptyOnNULL: COALESCE → "" → empty fallback
Handler (3 new tests):
- NamespaceLabelWithName_PrefersDisplayName: workspace/team/org/custom paths
- NamespaceLabelWithName_FallsBackToUUIDPrefix: empty displayName → legacy shape
- NamespacesToViews_PassesDisplayNameThrough: full integration on root case
Canvas: existing 30 tests still pass; suffix drop is rendering-only.
memories_v2.go function coverage: **14/14 = 100%**
- namespaceLabelWithName: 100%
- namespacesToViews: 100%
- (all 11 pre-existing functions stay at 100%)
## SSOT
The "what is this namespace called" question now has one source of
truth: namespace.Resolver.ReadableNamespaces sets DisplayName from the
canonical workspace.name column. The handler is a renderer; the
canvas is a consumer. No name-lookup logic duplicated across the
three layers.

Closes the silent-block failure mode that left 25 commits — including
the Memory v2 redesign and the reno-stars data-loss fix — wedged on
staging for 12+ hours behind a single missing review. The auto-promote
workflow opened the PR + armed auto-merge, but main's branch protection
required a human review and nobody noticed until a user reported
"still seeing old memory tab".
## Detection logic — `scripts/check-stale-promote-pr.sh`
Reads open PRs `base=main head=staging` and alarms on:
- `mergeStateStatus == BLOCKED`
- `reviewDecision == REVIEW_REQUIRED`
- createdAt older than `STALE_HOURS` (default 4h)
Other BLOCKED reasons (DIRTY, BEHIND, failed checks) are NOT alarmed —
those are the author's signal-to-fix. This script targets the specific
"no human reviewed yet" wedge.
Output:
- `::warning` per stale PR (visible in workflow summary + Actions UI)
- PR comment (idempotent via marker-string detection; one alarm
per PR, never re-spammed)
- Exit code = count of stale PRs (capped at 125)
Logic in a script (not inline workflow YAML) so it's:
- **Unit-testable** — tests/test-check-stale-promote-pr.sh exercises
every branch with stubbed fixture JSON + frozen clock. 23 tests
covering: empty list, single stale, just-under-threshold, wrong
reviewDecision, wrong mergeStateStatus, mixed list (only matching
PRs alarm), custom threshold via --stale-hours, exit-code-counts-
matching-PRs, --help, unknown arg → 64, missing repo → 2.
- **Operator-runnable ad-hoc** — `scripts/check-stale-promote-pr.sh`
works from any shell with `gh` + `jq`.
- **SSOT** — one detector, the workflow YAML is just schedule +
invocation surface. Future sibling workflows that need the same
check call the same script.
## Workflow — `.github/workflows/auto-promote-stale-alarm.yml`
Triggers:
- cron `27 * * * *` (hourly, off-the-hour to dodge cron herd)
- workflow_dispatch with `stale_hours` + `post_comment` overrides
Concurrency: `auto-promote-stale-alarm` group, cancel-in-progress=false
(idempotent script; no benefit to cancelling a running scan).
Permissions: `contents: read` + `pull-requests: write` (post comments).
Sparse checkout — only fetches `scripts/check-stale-promote-pr.sh`.
No node_modules, no go modules, no slow setup steps. Workflow runs
in <30s on a clean repo.
## Why "alarm + comment" not "auto-approve"
Considered options in issue #2975:
1. Slack/email alert — picked.
2. Bot-account auto-approve via molecule-ops — circumvents the
human-review gate that branch protection encodes.
3. Trusted-promote bypass via CODEOWNERS — needs Org Admin config
change; out of scope for a workflow PR.
The comment-on-PR pattern picks (1) without external dependencies
(no Slack token, no email config). Subscribers get notified via
GitHub's existing PR notification delivery; the warning shows up in
the Actions feed.
## Why this won't false-positive on legitimate slow reviews
Threshold is 4h. Most legitimate gates clear in <1h, so 4× headroom
is plenty for slow CI. The comment is idempotent (one alarm per PR,
never re-posted) — adding noise stops at 1 comment regardless of
how long the PR sits.
## Test plan
- [x] `bash scripts/test-check-stale-promote-pr.sh` — 23/23 pass
- [x] `python3 -c 'yaml.safe_load(...)'` clean
- [x] `bash -n` clean on both scripts
- [ ] Live verification: dispatch the workflow once main has caught up,
confirm it correctly reports zero stale PRs

/workspaces/d76977b1-…/files/config.yaml:1
Failed to load resource: the server responded with a status of 404
The workspace was an external-runtime mac-mini-style agent that
doesn't use the platform's config.yaml template — every Config tab
open issued a GET that 404d cleanly, and the existing catch block
fell into the runtime-manages-own-config branch + populated the
form from workspace metadata. Functionally correct, but the request
fired anyway, surfaced as a 404 in DevTools, and burned an RTT.
Fix: branch on RUNTIMES_WITH_OWN_CONFIG BEFORE the fetch — when the
workspace's runtime is one of those (external, hermes), skip the
GET, populate the form from workspace metadata directly, set
loading=false, return. Same code path as the existing 404-catch
fallback, just skipping the wasted request.
Behavior preserved for runtimes that DO use the template
(claude-code, etc.): unchanged GET → parse → setConfig flow.
Tests: 24/24 existing ConfigTab tests pass; no behavioral change for
the documented runtimes. tsc clean.

Closes#2973 — the followup test gap I flagged on PR #2968's review.
Pre-merge #2968 added the platform-pending: URI scheme branch to
resolveAttachmentHref + introduced the isPlatformAttachment SSOT
helper, but the existing uploads.test.ts only covered the older
workspace: / file:/// / absolute-path branches. The new branch shipped
on prod-impact (live console error on reno-stars) with manual post-
deploy verification; the regression gate was filed as a followup
(#2973) so a future canvas refactor can't silently re-break the
poll-mode chat-attachment download path.
Adds 15 new test cases across two existing describe blocks:
resolveAttachmentHref — platform-pending: scheme (poll-mode uploads):
- well-formed platform-pending:<wsid>/<fileid> resolves to the
/pending-uploads/<file>/content endpoint
- uses the URI's wsid, NOT the chat workspace_id (cross-workspace
forwarding case — pinning the explicit decision from #2968's
commit message so a regression that flipped this would mis-route
the download to the wrong workspace's pending-uploads store)
- defensive fallback to raw URI on missing slash, empty fileID,
empty wsid (so a future "helpful" change can't synthesize a
broken /pending-uploads// path)
- regression test against the EXACT production repro from #2968's
body (reno-stars, 2026-05-05 console error)
isPlatformAttachment:
- positive cases for platform-pending: (well-formed and malformed),
workspace:<allowed-root>, file:///<allowed-root>, absolute paths
under allowed roots
- NEGATIVE cases for HTTPS/HTTP URLs to other origins (auth-leak
class regression — a helper that always returned true would
attach workspace tokens to third-party requests), non-allowlisted
roots like /etc/passwd or /var/log/x, empty string, and
unrecognised schemes (s3://, ftp://)
All 21 tests pass. The 6 pre-existing tests are unchanged. The 15
new tests are the regression gate that #2973 asked for.
Verification:
- pnpm exec vitest run src/components/tabs/chat/__tests__/uploads.test.ts
→ 21 passed
The drift gate caught the new SSOT parser module — without registration
the wheel ships it un-rewritten and runtime imports fail. Same pattern
as inbox_uploads, a2a_tools_delegation, a2a_tools_rbac registrations.

Previously Phase 3 only checked the workspace-server's poll-mode short-circuit
emit shape ({"status":"queued","delivery_mode":"poll","method":"..."}); the
matching client-side classification was tested in isolation against fixture
dicts in test_a2a_response.py.
This phase closes the loop by piping the actual on-the-wire response from a
real workspace-server back through the wheel's a2a_response.parse() and
asserting it classifies as the Queued variant with the right method +
delivery_mode. A regression in EITHER the server emit shape OR the client
parser will now fail this E2E, eliminating the gap that allowed the original
"unexpected response shape" production bug to ship despite green unit tests.

Reported on production 2026-05-05:
agent plugin tab Plugins
0 installed
+ Install Plugin
this part should be default compact
Pre-fix: SkillsTab always rendered the Plugins section as a full
rounded-xl panel with vertical chrome — even when zero plugins were
installed and the registry browser was closed. The empty state
gave a lot of vertical real estate for content that's just "0
installed + Install button".
Fix: when installed.length === 0 AND registry closed AND initial
load completed, collapse the section into a single inline pill
("Plugins · 0 installed · + Install Plugin"). The full panel
re-mounts when:
- installed.length > 0 (a plugin landed → expand to surface the list)
- showRegistry === true (user clicked + Install Plugin → registry opens)
- !installedLoaded (avoid flash; the loading shell shows instead
until the first /plugins fetch resolves)
Accessibility:
- Compact pill: aria-label="Plugins (none installed)" + button
aria-expanded="false" + aria-controls="plugins-section"
- Full panel: button aria-expanded={showRegistry} + same aria-controls
- Section gets id="plugins-section" so the aria-controls reference
resolves once the section mounts
External workspaces: this is a pure canvas-frontend layout change —
applies to ALL workspace runtimes (external, claude-code, hermes,
langchain, codex, third-party MCP). No server-side change needed.
Tests
-----
SkillsTab.compactEmpty.test.tsx (4 tests):
- Compact pill renders when installed=0, registry closed, loaded
- Full panel renders when installed > 0
- Click + Install Plugin from compact → expands to full panel
(verified via aria-controls target id appearing in the DOM)
- During initial load (installedLoaded=false), compact pill does
NOT render — avoids a compact→full flash as the load completes
Per memory feedback_oss_design_philosophy.md: the SkillsTab is the
only tab that needs compact-empty today, but the pattern is
extractable into a shared EmptyStateCompactWrapper if Schedules /
Memories / Approvals adopt the same affordance later. Don't generalise
until the third use case (per the same memory, "every refactor toward
OSS plugin shape" without premature abstraction).
Verified
- tsc --noEmit clean
- All 4 tests pass

Introduce ``workspace/a2a_response.py`` as the single source of truth for
the wire shapes the workspace-server proxy can return at
``/workspaces/<id>/a2a``:
* ``Result`` — JSON-RPC success
* ``Error`` — JSON-RPC error or platform-level error (with
restart-in-progress metadata when present)
* ``Queued`` — poll-mode short-circuit envelope: the platform
queued the message into the target's inbox, the
target will fetch via /activity poll
* ``Malformed`` — anything the parser can't classify (logged at
WARNING so a future server change is loud)
``send_a2a_message`` (in ``a2a_client.py``) now dispatches via
``a2a_response.parse(data)`` instead of inline ``"result" in data`` /
``"error" in data`` sniffing. The Queued variant returns a new
``_A2A_QUEUED_PREFIX`` sentinel so callers can distinguish "delivered
async, no synchronous reply" from both success-with-text and failure.
reno-stars production data caught two intermittent failures that
both reduced to the same root cause:
1. **File transfer announce silently failed** — when CEO Ryan PC
(poll-mode external molecule-mcp) sent the harmi.zip
announcement to Reno Stars Business Intelligent (also poll-mode
external), ``send_a2a_message`` saw the platform's poll-queued
envelope ``{"status":"queued","delivery_mode":"poll","method":"..."}``,
didn't recognize it as the synthetic delivery-acknowledgement
it is, and returned ``[A2A_ERROR] unexpected response shape``.
The agent fell back to a chunk-shipping path; receiver did get
the file but operator-facing logs showed a failure that didn't
actually fail.
2. **Duplicated agent comm** — same bug, inverted direction. d76
delegated to 67d, send_a2a_message returned the unexpected-shape
error, delegate_task wrapped it as DELEGATION FAILED, the calling
agent retried with sharper wording, the recipient saw the same
request twice and self-reported "二次请求 — 我先不执行".
External molecule-mcp standalone runtimes are inherently poll-mode
(they have no public URL), so every external↔external A2A pair was
hitting this on every send. The pre-fix client only handled JSON-RPC
``result``/``error`` keys and treated the queued envelope (which has
neither) as malformed. RFC #2339 PR 2 added the queued envelope on
the server side; the client never caught up.
When ``send_a2a_message`` returns the ``_A2A_QUEUED_PREFIX`` sentinel,
``tool_delegate_task`` now transparently falls back to
``_delegate_sync_via_polling`` (RFC #2829 PR-5's durable
``/delegate`` + ``/delegations`` polling path, which DOES work for
poll-mode peers because the platform's executeDelegation goroutine
writes to the inbox queue and the result row arrives when the target
picks it up + replies). The agent gets a real synchronous reply
instead of the empty queued sentinel.
* ``test_a2a_response.py`` — 62 tests, **100% line coverage** on
the parser (verified via ``coverage run --source=a2a_response``).
Includes adversarial-input fuzzing across ~25 pathological
payloads — parser must never raise.
* ``test_a2a_client.py::TestSendA2AMessagePollMode`` — 4 tests for
the new Queued/Error wiring in ``send_a2a_message``.
* ``test_delegation_sync_via_polling.py::TestPollModeAutoFallback``
— 3 tests for the auto-fallback in ``tool_delegate_task``,
including negative cases (push-mode reply must NOT trigger
fallback; genuine error must NOT silently retry).
* **Verified all new tests FAIL on pre-fix source** by stashing
a2a_client.py + a2a_tools_delegation.py and re-running — 5
failures including ImportError for the missing
``_A2A_QUEUED_PREFIX``.
Per the operator-debuggability directive:
* INFO at every Queued classification (expected variant; operator
sees normal poll-mode-peer queueing in log stream).
* INFO at the auto-fallback decision in ``tool_delegate_task``
so a future operator can correlate "send returned queued →
falling back to polling path" without reading the source.
* WARNING at every Malformed classification (server contract
drift; operator MUST see this immediately).
* Existing transient-retry WARNING preserved.
* Mirror Go-side typed model in workspace-server. The wire shape
is documented in ``a2a_response.py``'s module docstring with
file:line pointers to the canonical emitters; a future PR can
introduce ``models/a2a_response.go`` without changing wire
behavior. The fixture corpus in ``test_a2a_response.py`` is
designed so a one-sided edit breaks CI.
* ``send_message_to_user`` and ``chat_upload_receive`` use a
different endpoint (``/notify``) and aren't affected by this
bug; their parsing stays unchanged.
* 135 tests pass across ``test_a2a_response.py`` +
``test_a2a_client.py`` + ``test_delegation_sync_via_polling.py``
+ ``test_a2a_tools_impl.py``.
* ``coverage run --source=a2a_response -m pytest`` reports 100%
line coverage with 0 missing.

workspace-server's a2a_proxy poll-mode short-circuit returns
{status: "queued", delivery_mode: "poll", method: <a2a_method>}
when the peer has no URL to dispatch to (poll-mode peers, including
every external molecule-mcp standalone runtime). The bare
send_a2a_message parser only knew about JSON-RPC {result, error}
keys, so this envelope fell through to the "unexpected response shape"
error path. Two production symptoms on the reno-stars tenant traced
to it:
1. File transfer logged as failed when it actually succeeded —
operator-facing logs showed an A2A_ERROR but the receiving
workspace did get the chunked file via the agent's fallback path.
2. delegate_task retried after the false failure → peer received
duplicate delegations → conversation got confused, the second
peer self-diagnosed in a notify ("⚠️ Peer 二次请求 — 我先不执行").
Add a third branch to the parser, BETWEEN the existing JSON-RPC
{result, error} cases and the catch-all "unexpected" fallback. The
queued envelope is delivery-acknowledged-but-pending-consumption —
not an error — so it returns a clean success string the agent can
render as a normal outcome. The success string includes "queued"
and "poll" so an operator scanning logs sees the routing path
without parsing JSON.
Defensive: the new branch only fires when BOTH status="queued" AND
delivery_mode="poll" are present. A partial envelope (one key
missing) still falls through to the catch-all, so a future server
bug that emits a malformed shape gets surfaced instead of silently
swallowed.
Tests:
- test_poll_queued_envelope_returns_success_string — pins the canonical
envelope returns a non-error string. Discriminating: verified to FAIL
on old code (returned [A2A_ERROR] string), PASS on new.
- test_poll_queued_envelope_with_other_method — pins the parser doesn't
hardcode message/send. Discriminating: also FAILS on old code.
- test_status_queued_without_poll_mode_still_falls_through — pins both
keys are required (defensive against future server bugs).
12 existing tests in TestSendA2AMessage still pass — no regression.
Scope: hotfix for the bare send_a2a_message path. The full SSOT
typed-A2AResponse refactor (#158-#163, parents under #2967) covers the
broader vocabulary alignment between Go server and Python client. This
PR ends the production symptoms now without preempting that work.
Followup to PR #2966. The user reported the about:blank symptom on
reno-stars and the browser console showed:
Failed to launch 'platform-pending:d76977b1-…/bb0dcaf3-…' because
the scheme does not have a registered handler.
So the agent's "download link" was a `platform-pending:<wsid>/<file_id>`
URI — the canonical reference for poll-mode chat uploads (see
workspace-server/internal/handlers/chat_files.go:690 +
workspace/inbox_uploads.py). PR #2966 only handled `workspace:`,
`file:///`, and absolute container paths; the platform-pending
scheme fell through to the raw URI which the browser couldn't
navigate to.
Fix
---
- `resolveAttachmentHref`: added a `platform-pending:` branch that
resolves to `${PLATFORM_URL}/workspaces/<wsid>/pending-uploads/
<file_id>/content`. Uses the wsid from the URI, NOT the chat's
workspace_id — these can differ when a file is forwarded across
workspaces (cross-workspace delegation, agent forwarding).
- New `isPlatformAttachment(uri)` helper — single source of truth
for "this URI requires our auth headers, route through
downloadChatFile". Used by both `downloadChatFile` (chip click)
and ChatTab's markdown-link override.
- ChatTab.tsx markdown-link override now imports
`isPlatformAttachment` instead of duplicating the scheme list.
Pre-fix this list was duplicated and missed `platform-pending:`.
Tests

The 4 IME tests still pass; tsc clean. The platform-pending resolution
is exercised via the `isPlatformAttachment` SSOT helper (any URI
reaching `downloadChatFile` or the markdown override goes through
it). A dedicated test for the URL shape would need a more elaborate
fixture; manual verification on staging post-deploy is the practical
gate.

Two production-reported regressions in the same chat surface, fixed
in one focused PR.
Issue 1 — IME composition + Enter sends half-typed message
----------------------------------------------------------
ChatTab's textarea onKeyDown was:
if (e.key === "Enter" && !e.shiftKey) {
e.preventDefault();
sendMessage();
}
For agents typing CJK / Japanese / Korean via the system IME, Enter
commits the candidate selection — not a newline, not a send. With
the old check, every IME-commit Enter accidentally sent the
half-typed message ("你好" + half-typed-pinyin + Enter to commit
the next candidate → message goes out before the user finishes).
Fix: guard on `event.nativeEvent.isComposing` AND `e.keyCode !== 229`.
The latter covers older Safari / WebKit-based mobile browsers that
delay setting isComposing on the composition-end Enter.
Issue 2 — markdown links land at about:blank
---------------------------------------------
ReactMarkdown's default `<a>` rendering passes the agent-supplied
href directly to the DOM with no target / scheme handling:
- http(s) → navigates the canvas tab away (canvas state lost)
- workspace://path / file:///workspace/... / /workspace/... →
browser hits unhandled-protocol click → about:blank, no
download (the reported bug)
Fix: ReactMarkdown `components.a` override:
- In-container paths (workspace:, file:///{workspace,configs,home,
plugins}, bare /{workspace,configs,...}) → preventDefault, route
through downloadChatFile (same auth path the AttachmentChip
uses). Filename is derived from the path's last segment.
- External (http/https/mailto/unknown scheme) → target="_blank"
rel="noopener noreferrer" so canvas state survives.
Tests
-----
ChatTab.imeAndLinks.test.tsx (4 tests):
- Enter with isComposing=true → does NOT send, input preserved
- Enter with keyCode=229 (older-Safari IME) → does NOT send
- Enter with no IME signal → DOES send (happy path intact)
- Shift+Enter → does NOT send (newline path intact)
The link-component override is exercised through the full ChatTab
render — the IME tests are jsdom-only and don't load chat history
with markdown messages, so the link test would need a more elaborate
fixture. Manual verification on staging post-deploy is the practical
gate; if the link test grows critical the AttachmentViews-style chip
test can extend.
Verified:
- tsc --noEmit clean
- 4/4 IME tests pass
