feat(projects): project workspaces with scoped chats and thread membership (#5265)
* feat(projects): project workspaces with scoped chats and thread membership

Backend:
- projects table model and migration; fail-closed ProjectRepository with
  ownership checks, CRUD/archive/restore/delete router, and atomic thread
  move between projects
- threads_meta.project_id column exposed as reserved deerflow_project_id
  metadata; project-aware thread create/search with pagination bounds and
  membership echoed in create responses
- first-run admission assigns the project only at genuine first run, seeded
  at write time and dropped when invalid; serialized against project
  deletion and thread assignment
- branch creation inherits the source thread's project membership (an
  archived/deleted project degrades the branch to unassigned instead of
  failing the request)

Frontend:
- projects data layer, thread move API, and sidebar projects section with
  flat/grouped modes, archived-project threads, and stable virtual-list
  offsets
- project detail page with project-scoped new chat
  (/workspace/chats/new?project=) and paginated thread list
- move-to-project thread menu, new-project dialog, archived-project gates
- project-scoped new chats pre-create the thread with membership before the
  first submit or /goal set, so runs never proceed outside the project
- goal-set preparation is fenced against conversation switches: a stale
  continuation is dropped instead of saving the goal or launching the
  abandoned submission on the newly opened conversation
- project thread lists join thread lifecycle invalidations (stop, pin) so
  an open project page never keeps stale titles, recency, or pagination

* fix(chats): keep archive undo toast when the sidebar row unmounts

The archive success toast was fired from per-mutate callbacks passed to
mutation.mutate. React Query drops those handlers when the observer
component unmounts before the mutation settles; archiving the open chat
removes its sidebar row mid-flight, so the undo toast never appeared and
the e2e archive-undo test timed out waiting for it.

Move the success/error handlers to the mutation level (useArchiveThread
options, same pattern as useMoveThreadToProject) where callbacks are
delivered even after the originating row unmounts.

* fix(projects): pin project thread listing contract and exclude archived chats

GET /api/projects/{id}/threads returned the thread store row verbatim
(list[dict], no response_model): user_id/assistant_id leaked, any future
ThreadMetaRow column would auto-leak, and the OpenAPI schema was empty.
Return a narrow ProjectThreadResponse (the exact fields ProjectThread
declares) with the same metadata secret redaction the surrounding thread
endpoints get from _MetadataRedactingResponse.

The listing also ran search() without the archived filter, so a retired
chat rendered as a normal row on the project page while the sidebar hid
it. Search archived=False to mirror the sidebar's archived:false lists;
restore stays on the global Archived tab.

Both regressions pinned by new router tests: wire-shape allowlist and
archived-member exclusion.

* docs(migrations): record the 0019/0020 chain against the bootstrap reservation

The tree now chains 0018 -> 0019_projects -> 0020_threads_meta_project_id,
so migrations/AGENTS.md was stale twice over: the revision index stopped at
0018 and the rolling-forward section still claimed the tree 'deliberately
remains at 0018'.

Document the new head and record the intentional numeric-prefix reuse of
0019: 0019_projects is in-chain while 0019_thread_incarnations stays the
reserved, allowlisted out-of-tree rollout id. The owning rollout revision
must re-parent onto this tree's head when it merges so alembic never sees
two heads off 0018; bootstrap.py now cross-references that note next to
_FORWARD_COMPATIBLE_REVISION.

* fix(chats): invalidate project thread lists on archive/restore

useArchiveThread refreshed the infinite sidebar cache, threads/search and
the per-thread metadata cache but not the project-scoped list
([...PROJECTS_QUERY_KEY, 'threads', id]) this PR adds — the one thread
mutation not wired to that key, after usePinThread, useRenameThread,
useDeleteThread, useMoveThreadToProject and invalidateStoppedThreadCaches.

An archive from a sidebar row while a project page is open therefore left
the archived chat rendered as a normal row until remount (and undo left it
missing). Invalidate the prefix in the mutation-level success handler.

Regression test asserts the project-list prefix is invalidated on success.

* fix(projects): fetch project discovery only in grouped sidebar mode

RecentChatList mounted two useProjects queries per sidebar render, but
knownProjectIds is consumed only by the grouped-mode exclusion filter; in
the default flat mode every page load paid two GET /api/projects?status=
round trips for data nothing read. Gate both queries on grouped mode —
GroupedProjectList fetches the same keys when the toggle is on and
TanStack dedupes the observers.

Also set retry: false on useProject: a deleted or foreign project 404s
deterministically, and the page renders a dedicated not-found state for
it, so the default 1s/2s/4s retry backoff kept deep links in 'loading'
for ~7s before that state appeared. Matches useThreadMetadata /
useThreadTokenUsage.

* fix(threads): fail closed on project-scoped create in memory mode

MemoryThreadMetaStore.create accepted project_id and silently ignored it,
making memory mode the one membership path that fails open: POST
/api/threads with a project id returned 200 and the run started
unassigned, violating the invariant that a run never proceeds outside the
selected project (the SQL store raises ProjectNotAssignableError inside
the insert transaction for the same request).

Raise ProjectNotAssignableError whenever project_id is present so the
router's existing 404 mapping applies, the frontend keeps the composer
text for a retry, and memory mode behaves exactly like SQL mode.
set_project already reports rejection; create now matches it.

Store-level test (raises, nothing persisted, project filter stays empty,
unscoped creates still work) plus a router-level test asserting the 404
and that no row is left behind.

* fix(projects): window the project page thread list

ProjectThreadsSection rendered every loaded page as a plain Link row, so a
long-lived project accumulated unbounded DOM on the page's scroll surface:
each load-more appended another 100 rows and every formatTimeAgo tick
re-rendered the whole list.

Reuse VirtualThreadList (now generic over any row shape with a
thread_id), pointing its scroll parent at this page's ScrollArea viewport
via the shared [data-slot="scroll-area-viewport"] selector used by
/workspace/chats; under the 60-row threshold it falls back to the plain
render, so small projects are unchanged.

* fix(projects): restore row dividers and pin them with a render test

The row class template literal concatenated transition-colors directly
with the conditional border-b token, so non-final rows rendered the
invalid class 'transition-colorsborder-b' and lost both the divider and
the transition. Compose the row classes with cn() and a boolean guard
instead.

The section moved out of page.tsx into a testable component so the row
markup finally has coverage: a DOM test asserts every row except the
final data row carries border-b (index-based, not last: — correct under
virtualization where the last mounted row is not the last data row), and
the untitled fallback plus load-more button render for a partial page.

* fix(projects): validate forward schemas and fence membership reads

fix(runs): reject cancel actions on GET stream joins (#5092)
* fix(runs): reject cancel actions on GET stream joins

stream_existing_run is registered for both GET and POST, and its
?action=interrupt|rollback branch cancels the run. The CSRF middleware
exempts GET, so a session-authenticated browser could be forced
cross-site (img/script/top-level navigation) into
GET /api/threads/{id}/runs/{run_id}/stream?action=interrupt|rollback —
a state-changing GET that bypasses the CSRF protection guarding the
POST variant. Introduced with the dual registration in #1403.

The handler's docstring already documents cancel-then-stream as
POST-only (the LangGraph SDK's joinStream/useStream stop button uses
POST); enforce it: GET with an action answers 405, action-less GET
joins and POST cancel-then-stream are unchanged.

Regression drives the real router: GET+action is 405 with the run left
running, plain GET join still streams, POST+action still cancels.

* fix(runs): scope the 405 detail to the action requirement

"GET is a read-only stream join" overstates the current main: on a
locally-owned run with the default on_disconnect=cancel, a GET join's
disconnect can still trigger cancellation. That observer-disconnect
vector is closed by #5041; the detail here should only claim what this
guard enforces.

* fix(runs): harden GET stream action rejection

* fix(runs): align stream schema with method contract

* test(runs): pin GET stream action 405 through the production stack

Review follow-up (defence-in-depth): the GET-action suite drove bare
FastAPI() apps, so nothing pinned that a session-authenticated
cross-site GET reaches the route gate at all once CSRF exempts the
safe method. test_pat_auth.py already assembles the production
middleware order (AuthMiddleware inner, CSRFMiddleware outer), so its
mirror app now registers the real _reject_get_stream_action
dependency on a GET join route.

The new case pins the end-to-end premise: an authenticated GET
?action=interrupt is answered 405 + Allow: POST by the production
route dependency, while the same unauthenticated GET dies at
AuthMiddleware's 401 before any route logic runs.

Validation: focused suites (test_pat_auth, test_stream_get_action,
test_csrf_middleware) — 62 passed; ruff check + format clean; the new
case errors on the pre-fix baseline (guard absent), confirming the
pin.

feat(auth): add personal access tokens for programmatic API access (#5041)
* feat(auth): add personal access tokens for programmatic API access (#4849)

Backend-first implementation of the PAT contract from #4849: show-once
dfp_ tokens bound to their owning user (AUTH_SOURCE_PAT,
is_internal=false), digest-only storage (migration 0017), strict
credential precedence (invalid Bearer is a 401, never cookie fallback),
CSRF double-submit skipped only for Bearer requests while
auth-endpoint origin checks still run, scopes intersecting the authz
route permissions, session-auth-only PAT management and password
changes, and throttled best-effort last_used_at stamps.

* fix(auth): harden PAT scope boundary and schema parity from adversarial review

Independent review of the initial draft found: (1) scopes only constrained
the threads/runs permission axis while admin routes treated a PAT as its
(possibly admin) owner — is_admin_user now rejects PAT callers outright
since no scope grants admin capability; (2) the model declared a column
UNIQUE constraint while migration 0017 created a named unique index, so
downgrade failed on create_all-bootstrapped DBs — both now use the named
unique index; (3) auth-disabled mode is an operator override and now stays
ahead of the Bearer check so a stray Authorization header cannot 401 an
E2E sandbox; plus wiring the previously-unused constants, bounding the
last_used_at stamp cache, and four new tests (middleware-level expiry,
expires_in_days, admin-capability rejection with session control, and the
auth-disabled precedence).

* docs(api): document personal access tokens for programmatic API access

* fix(auth): close PAT security boundaries from review (default-deny routes, extension admin suppression)

P1-1: scope intersection only constrains @require_permission routes, so
undecorated mutation routes (DELETE /api/memory, POST /api/agents, Lark
credential switching, channel config) accepted a PAT holding a single read
scope. AuthMiddleware now enforces a default-deny route policy in
auth/pat.py: PAT requests are admitted only to the thread/run lifecycle
routes the v1 scopes govern; everything else answers 403 regardless of
scopes. Session-cookie callers are unaffected.

P1-2: the extension principal resolver projected is_admin/roles from the
raw system_role, so an admin-owned PAT passed
deerflow_extension_api.require_admin on contributed routes despite the
documented no-admin guarantee. The projection is now PAT-aware and
suppresses every admin signal for PAT callers, mirroring
deps.is_admin_user.

Both fixes carry regression tests (route outside policy 403 + session
control; production resolver admin suppression), and API.md documents the
default-deny boundary.

* fix(auth): enforce PAT scopes on stateless run entry and harden decorator

Follow-up hardening from an independent audit of the P1 fixes:

- POST /api/runs/stream and /api/runs/wait were the only allowlisted run
  entrypoints without @require_permission, so a threads:read-only PAT
  could still start runs (same bug class as P1-1, now closed): both now
  carry @require_permission("runs", "create"). POST /api/threads and
  POST /api/threads/search gain threads:write / threads:read for the
  same reason. Authorization-disabled deployments see no change (the
  permission set resolves to all permissions).
- require_permission now binds the wrapped signature to locate a
  positionally-passed request before injecting the test stub, fixing
  'got multiple values for argument' on direct positional unit-test
  calls.
- API.md: the intro PAT example used GET /api/models, which the new
  default-deny policy 403s — replaced with GET /api/threads; the
  default-deny route list now spells out method sets.

Regression test: threads:read-only PAT is 403 on the decorated stateless
entry while a runs:create PAT passes.

* fix(auth): address review P2s (empty Authorization header, PAT name trimming, API example)

- CSRFMiddleware treats an explicitly empty Authorization header as
  present (is None), so an invalid credential always reaches
  AuthMiddleware's uniform 401 instead of a CSRF 403 that varies by
  method/CSRF state. Regression: empty-header request dies at auth.
- PATCreateRequest strips the name and rejects whitespace-only values
  before token generation; created names are stored trimmed.
- API.md intro PAT example now uses the implemented
  POST /api/threads/search endpoint (GET /api/threads does not exist).
- AGENTS.md trimmed back under the guidance soft budget after the
  upstream merge.

* fix(auth): tighten PAT route policy to implemented methods only

The allowlist admitted GET /api/threads, a method no router implements.
Pre-authorizing a dead method weakens the default-deny boundary: a
future GET collection route added without a permission decorator would
become PAT-reachable without an explicit policy change. Restrict the
rule to POST, fix the stale GET description in API.md's PAT
constraints, and document the default-deny boundary accurately in the
gateway AGENTS.md guidance (only the threads/runs allowlist is
PAT-reachable; every other authenticated route 403s PAT callers).

Audited every remaining rule against the mounted routers: all other
method+path entries map to real routes. Regression:
test_pat_policy_does_not_pre_authorize_unimplemented_methods.

* test(auth): guarantee the negative digest test mutates the token

token[:-1] + "X" is identical to the original whenever the generated
token already ends in X (1/62), making the negative digest assertion
fail intermittently. Choose the replacement character based on the
existing tail so the mutated token always differs.

* fix(auth): require runs:cancel for cancel-then-stream requests

stream_existing_run is gated at runs:read so action-less stream joins
work with read-only credentials, but its ?action=interrupt|rollback
branch cancels the run — a separate permission. A runs:read-only PAT
passed both the PAT route policy and the route decorator and could
interrupt or roll back an active run, bypassing the runs:cancel scope.

Decorators cannot express query-parameter-conditional permissions, so
the check lives in require_cancel_permission_when_action(), applied at
the top of the handler. Regression drives the real helper through the
production middleware: runs:read-only PAT + action is 403, the same
token joins action-less, runs:read+cancel passes, session control
unaffected.

* docs(changelog): add the PAT feature entry

* docs(readme): add personal access tokens section

Repo documentation-update policy requires user-facing features to
update README.md in the same changeset; the PAT feature previously
touched only backend/docs/API.md and the gateway AGENTS.md.

* fix(auth): require runs:cancel for mutating multitask strategies

All five run-creation entrypoints were gated only by runs:create, but
RunCreateRequest.multitask_strategy accepts interrupt/rollback and
start_run forwards it to create_or_reject, which terminates an
already-active run. A runs:create-only PAT could therefore kill an
existing run through a create request, bypassing runs:cancel.

Decorators cannot express body-parameter-conditional permissions, and
per-route checks leave the same hole for the next entrypoint, so the
gate lives in start_run itself — the single choke point every
run-creation path (HTTP routes and internal launchers) flows through.
Regenerate launches pass multitask_strategy="reject" and are
unaffected; requests without a stamped auth context (internal/test
compositions) skip the gate.

The check is the shared authz.require_cancel_permission_if primitive;
require_cancel_permission_when_action now delegates to it, so every
request dimension that carries cancel capability (query action, body
strategy) flows through one gate.

Regression drives the real middleware stack: runs:create-only PAT +
interrupt/rollback is 403 with the exact detail, reject (explicit and
default) stays available, runs:create+cancel passes, session control
unaffected; a source anchor pins the gate inside start_run.

* fix(runs): keep observer joins from applying creator cancel-on-disconnect

sse_consumer's finally block applied the record's on_disconnect=cancel
policy on ANY consumer's disconnect. The join surfaces (GET /join and
the action-less GET/POST stream join) feed it the existing RunRecord,
so anyone with thread read access — including a runs:read-only PAT —
could cancel a locally-owned running run simply by closing the SSE
connection, without runs:cancel. The policy expresses the creator's
intent for their own connection; an observer's disconnect must never
be read as that intent.

sse_consumer gains apply_on_disconnect (default True). The two join
surfaces pass False; the creating endpoints (thread-scoped and
stateless create-and-stream) keep the creator semantics unchanged.
wait_for_run_completion needs no change: its callers are creator-side
or post-explicit-cancel paths only.

Regression exercises a real generator close — the same machinery
Starlette drives on client disconnect — against the production
sse_consumer: creator stream disconnect cancels, observer join
disconnect does not; a wiring anchor pins both join call sites and the
creator defaults. API.md documents the cancel-capability constraint
(this fix plus the action/strategy gates) in PAT Constraints.

* test(auth): pin the multitask gate behaviorally; state wait invariant

Independent adversarial review of the round-5 fixes found the P1-a
regression only mirror-pinned: the source anchor could be satisfied by
a comment, and deleting the gate from start_run would not fail the
suite. This drives the production start_run directly — a create-only
auth context gets 403 with the exact detail for interrupt, and a
reject request with no cancel permission at all proceeds past the gate
(never a permission 403).

Also documents wait_for_run_completion's creator-side invariant
(every caller is the creating endpoint or post-explicit-cancel) so a
future observer wiring thinks twice before reusing it — the one-caller-
away variant of the observer-disconnect P1.

* docs(changelog): correct the PAT entry's digest and route-policy description

The entry said HMAC digests (the implementation stores SHA-256 digests,
as documented in API.md and pinned by the repository tests) and claimed
the route policy admits 'implemented stateless endpoints' (it admits
the thread/run lifecycle routes, narrowing further by scopes). Also
notes the cancel-capability gate now covering action and multitask
strategies.

* fix(auth): enumerate the PAT runs route policy per implemented subroute

The runs subtree rule was a GET|POST /runs(/.*)? wildcard — it
pre-authorized every current and future subroute under /runs, including
methods the router never implemented (e.g. GET /runs/stream), which is
the same latent default-deny weakening the threads collection rule was
tightened for: a future route added under /runs would become
PAT-reachable without an explicit policy change.

The wildcard is replaced with six segment-precise rules covering exactly
the 14 implemented method+path combinations; the {run_id} slot
necessarily matches any single segment, so the POST-only collection
names (stream, wait, regenerate, edit-regenerate) are excluded from the
GET run-id rule via negative lookahead — no dead method stays
pre-authorized. Behavior for implemented routes is unchanged.

test_pat_runs_policy_admits_exactly_the_mounted_routes derives the
expected set from the mounted thread_runs router instead of a
hand-maintained list: every implemented GET/POST route under /runs must
be admitted, routes in this router outside the subtree stay denied, and
representative unimplemented neighbors are denied — so adding a route
under /runs now fails CI until it is explicitly allowlisted, and a
removed route leaves a dead rule visible. API.md's PAT constraints list
the enumerated routes and drops a feedback mention that belonged to the
stateless /api/runs axis.

* docs(migration): add the 0017 renumbering coordination note to 0017

The PR's migration-coordination comment states each migration file
carries the note; the file did not. Adds it: numbering was generated
against main head 0016 alongside #5078 and #4843; whoever merges first
keeps the slot, the others renumber on rebase (revision/down_revision
plus the bootstrap head assertions).

* fix(auth): pad base62 tokens to a fixed 43-char width

int.from_bytes discards leading zero bytes, so the unpadded encoder
returned a variable-length body — empty for all-zero input, and shorter
than 40 characters for any draw below 62**39 (~1 in 14.5M), leaving
test_generate_pat_token_format probabilistically flaky and the token
body without stable width (review round 6, P3).

_base62 now left-pads with "0" to _base62_width(len(data)) — the exact
integer digit count (62^43 > 2^256 > 62^42, so 43 for 32 bytes). The
format test asserts the exact fixed width instead of a probabilistic
floor, and a new unit test pins the all-zero, leading-zero-byte, and
max-value edges deterministically.
