* fix(uploads): keep OSError text out of upload, delete and attach 500s
Thread upload, upload delete and shelf attach-to-thread put str(exc) in
their 500 detail. A staging or unlink OSError names its file, so a
permission error, or a disk too full for mkstemp, returned the absolute
host path of the thread's uploads directory, user and thread IDs included.
Return a fixed detail that still names the caller's file. The existing
error log lines keep the full message for operators.

* fix(projects): check the project before staging shelf uploads
The shelf upload and save-from-thread routes staged the body under
users/{user_id}/projects/{project_id}/ before checking the project. A
missing, foreign, or archived id left an empty {project_id}/documents/
directory that the retention sweep keeps forever, and an id longer than
one path component failed with ENAMETOOLONG (500).
Both routes now require an owned, active project first and answer the
same 404 without writing. The shelf insert still re-checks under the
project row lock.
* test(projects): pin the shelf insert's re-check behind the early project check
With the early check in place, no route test reached the insert's
row-lock re-check any more. Archive the project between the check and
the insert and assert both routes still answer 404 and leave no staging
file.

* docs(changelog): drop the whitespace-only line after the zh #7040 entry

* fix(uploads): reject filenames reserved for temporary staging
Guard thread and shelf upload names, validate SDK batches before copying, and preserve legacy shelf downloads. Add regression coverage and document the reserved staging namespace.
* fix(uploads): report reserved names before HTTP batch ingestion
Preflight reserved staging basenames before thread storage or sandbox setup. Return HTTP 400 with a rename hint; add HTTP and strict blocking-I/O regressions and update upload documentation.
* fix(uploads): reject Windows-style staging basenames on POSIX
Normalize backslashes before the HTTP reserved-name preflight. Add POSIX basename regressions for single and mixed batches and strict blocking-I/O coverage. Clarify the preflight scope and upload documentation.

* feat(projects): Projects MVP Phase 2 — instructions, document shelf, promotion, trash
Implements docs/superpowers/specs/2026-09-12-projects-mvp-phase2-design.md
(issue #5160, tracker #5129) in the slice order of the spec's §16.
Slices:
- A: ProjectsConfig + write-time 422 UTF-8 byte cap; PROJECT_CONTEXT_KEY
admission pinning (both server-owned sets + worker hoist); latest-only
request-scoped <project> block via DynamicContextMiddleware
wrap_model_call/awrap_model_call (idempotent reassembly, reserved ID
prefix + marker + provenance, never persisted); journal audit
fingerprints; Instructions tab.
- B: ProjectDocumentRow + migration 0023; ProjectDocumentRepository with
locked check-and-set; hash-qualified immutable shelf storage with
Paths helpers; upload/list/content/delete-to-trash routes; project
delete trashes the shelf in-transaction; request-scoped bounded
<documents> index with honest count/shown + actionable overflow note;
list_project_documents/read_project_document tools registered only on
pinned runs; PAT allowlist + drift guards; blocking-IO anchors.
- C: shared thread-upload ingestion service (uploads router refactored to
parity); POST from-thread with provenance; attach-to-thread with
lock-staged copy (archived source allowed); read-only thread-files
view with per-group truncation reporting.
- D: restore (restored/merged/not_found/no_target/content_missing; no
file moves), purge (continuous row lock across unlink/delete/commit,
retryable on FS errors), retention sweep (lazy + startup, 24h orphan
guard, row-side reconciliation never deletes).
- E: Documents tab (shelf + conversation-files browser, provenance,
archived banner, content-missing rows), /workspace/trash route,
sidebar entry, composer attach handoff, i18n (en-US/zh-CN), e2e mocks
+ specs.
Review hardening folded in (10 rounds, all with tests):
- force active shelf content (HTML/XML family) to download; nosniff on
artifact + content responses; unified unsandboxed-iframe PDF preview
(fixes the pre-existing Chromium sandbox blank in the artifact viewer)
- scope document trash to the URL project under the document lock
- atomic no-overwrite filename reservation for ALL ingestion (seeded
claims + os.link commit with suffix retry; same-name re-upload now
unique-names instead of replacing); hidden staging only, no visible
placeholders; lease cleanup on setup failure
- serialize conversion under the document lock with post-lock active
revalidation; drain locked filesystem work on cancellation; preserve
bytes when an insert's commit state is uncertain (including trashed
rows)
- original-integrity checks before serving text or cached conversions;
content_missing surfaced in list responses (UI reads the flag, no
409-probe); downloads always serve original bytes
- bounded streaming document reads with cached char counts; shelf limits
declared in middleware release identity
- thread-root confinement for from-thread sources; config fallback
rejects fractional/infinite values; composer counts staged
attachments; pending attachments persist until submission or removal;
in-flight instruction/rename edits survive save refetches; shelf and
trash pagination; conversation-file and thread-files pages stay
subscribed to refetches

Review follow-ups (head b4807477 → this revision):
- The trash retention sweep is split so repeated lazy triggers stay
bounded: the indexed expiry purge still runs on every trigger
(GET /api/trash/documents, POST /api/trash/purge) while the
O(all rows + all files) reconciliation is throttled to one run per
user per 15 minutes (process-local, per-user window). The startup
sweep now runs as a background task instead of blocking gateway
readiness, and shutdown awaits it (bounded).
- The export scrub (stripInternalMarkers) is fence- and indentation-aware
like the render path, so a pasted, fenced <project>/<documents> snippet
survives markdown export while real injected blocks (never fenced) are
still removed. Fence regexes moved to a dependency-free leaf module to
avoid the messages↔streamdown import cycle.
- The artifact viewer's PDF iframe no longer carries an added title
attribute (the upstream e2e contract locates it via :not([title])), and
the upstream artifact-preview spec now pins the new contract: PDFs
render unsandboxed, images keep sandbox="".
* fix(projects): round-2 review — cancel an overrun trash sweep, restore the PDF frame title
- Shutdown cancelled only the shield around the background startup sweep,
so an all-users reconciliation that outlived the 5s budget kept walking
rows and files while the document repo and DB engine were disposed
underneath it. The wait now lives in `_shutdown_startup_trash_sweep`,
which cancels the task and drains it before worker exit: the shield
keeps the wait bounded, the cancel makes it final (CancelledError lands
at the sweep's next await, and `_run_startup_trash_sweep` only catches
`Exception`, so nothing swallows it).
- The browser-preview iframe lost `title={getFileName(filepath)}` in the
previous fix round, leaving the PDF frame without an accessible name
while its siblings keep theirs. Restore it (WCAG frame titles), assert
it in the DOM test, and anchor the e2e on `iframe[title="report.pdf"]`
instead of `iframe:not([title])`.
* fix(projects): round-3 review — report the sweep's late finish, not a phantom cancel
`Task.cancel()` returns False when the sweep already finished inside the
window between the deadline firing and the cancel, so the shutdown log
claimed a cancellation that never happened. Branch on that outcome: the
warning stays for a real cancel, a late finish is logged at info, and both
paths still reap the task before worker exit.
* fix(projects): round-4 review — make Empty trash delete what it confirms
`POST /api/trash/purge` only ran the retention sweep, and the sweep's
candidate selection is age-gated, so a freshly trashed document survived
"Empty trash" even though the confirmation promises that every listed
document is permanently deleted. With one trashed row the route answered
`{"purged": 0}` and left it in place; `GET /api/trash/documents` sweeps
expired rows before listing, so the visible rows were normally ineligible
for the action by construction.
Empty trash now drives `purge_all_trashed`: the caller's trashed rows
(`list_all_trashed`, no age filter) each go through the same guarded,
row-locked `purge` as the single-document delete — bytes first, then the
row, in one transaction — so a row restored mid-flight is skipped instead of
force-deleted, and an unlink failure rolls that row back and answers 500 with
a retryable message. Retention expiry stays where it was: the sweep's
`purge_candidates` is now the only age-gated selection, and the lazy
retention sweep still runs on the listing and at startup.
Tests: the router suite replaces the retention-gated expectation with the
reviewer's repro (fresh row purged, bytes unlinked, shelf and other users'
trash untouched, a failing unlink stays retryable and 500); a blocking-I/O
anchor drives the new entry point through the offload; the mocked e2e covers
the action end to end; a new real-backend spec performs it against the real
gateway and re-reads `GET /api/trash/documents`. README, API, ARCHITECTURE
and the phase-2 design docs (en+zh) state the age-independent contract.
