- channels CB3: sort discovery rows NULLs-last (title is None) to match the DB
ORDER BY exactly — coercing NULL title to "" floated untitled channels to the top.
- AdminUsers SC1: track in-flight rows in a Set, not a single id — per-row disabling
now lets the admin start concurrent row actions, and a shared id was cleared by
whichever settled first (re-enabling a still-pending row → possible double-submit).
- ChatThread CT4: reset the incoming-count ref when partnerId changes — the Messages
page reuses one ChatThread across conversation switches, so a same-count switch
could skip the open-marks-read badge refresh.
- messages MB3: push a bare {type:"unread"} (drop the now-dead count query — the
client re-fetches on the signal and ignored the number anyway).
- api.ts: extract the shared keepalive `beacon()` helper (saveProgressBeacon +
plexProgressBeacon were near-verbatim copies).
Verified each deferred per-subsystem item against current source, then fixed the
real ones (tradeoffs left as-is, see siftlode-ops/CODE-HYGIENE.md closeout):
- search BUG-3: don't finalise shorts_probed on un-enriched stubs (enrichment
failure/omitted rows) — restores the scheduler's enriched_at guard so a real
Short can't leak into the feed and never get reclassified.
- downloads GC: 4th pass reaps orphaned errored, fileless, unreferenced assets
(they carry no TTL, so the expiry passes never cleared them).
- downloads B6: quota/edit errors now return a structured {code,reason,limit}
the trilingual client localises, instead of hardcoded English + dot-decimal GB.
- channels BB1: reset-backfill re-arms deep sync on every subscriber (bulk update)
instead of 404ing when the admin isn't personally subscribed.
- channels BB2: enrich the stub on BOTH the normal and "already exists" desync
path (nest the insert try inside the client `with`).
- channels CB3: drop the redundant second _discovery_rows read (identity-mapped
rows are already enriched; re-sort in Python for the title tie-break).
- playlists PC1: read the live playlist once in push() and share it with plan_push
+ push_playlist (halves read-quota, closes the second TOCTOU window).
- playlists PC2/PC5: batch the cover thumbnails in one window query (was N+1);
rename combines count+duration into one aggregate + a single cover lookup.
- messages MB2: get_thread only resolves a messageable partner OR one we already
share a thread with (closes the user-enumeration oracle).
- messages MB3: push a live unread-count to the user's other tabs after mark-read.
- messages MC4: list_conversations uses DISTINCT ON + grouped COUNT instead of
loading the whole message history into memory.
- config AB3: per-spec allow_empty so smtp_user/youtube_api_proxy can be blanked
to disable them rather than snapping back to the env default.
resolved_user_id already accesses ws.session unguarded just above (SessionMiddleware
covers the WS scope), so the '"session" in ws.scope' fallback was dead code — read
ws.session directly for consistency (review follow-up).
Loose ends to finish the auth security round:
- register + password-reset-request had an enumeration TIMING oracle: an already-
registered email skipped the create path (hash + row writes + email scheduling) and
responded measurably faster than a new one. Move the whole lookup+create (register)
and lookup+token+email (reset) into a background task with its own DB session, so the
endpoint returns in the same time for any valid email regardless of whether it exists.
Verified: existing vs new now ~equal (was 34ms vs 82ms on register); accounts/tokens
still created off-path.
- messages_ws re-implemented resolved_user_id's per-tab wallet-gated account resolution.
Generalize resolved_user_id to take any HTTPConnection (Request OR WebSocket) and call
it from the WS — one shared, wallet-gated resolution. Behavior-identical (unit-checked).
Adversarial re-review of the session-epoch work surfaced:
- WS auth (messages_ws) skipped the epoch check, so a revoked-but-unexpired cookie
could still open the live push channel after a reset/logout-others. Now mirrors
current_user: loads the user once, rejects a stale-epoch cookie before connecting.
- set_password + logout_others re-stamped the cookie BEFORE db.commit(); a failed
commit would strand the current session at a newer epoch than the DB and wrongly
401 it. Commit first, then re-stamp.
- Welcome verify effect could double-POST the single-use token (StrictMode/remount)
and flip the banner to a false 'invalid'. Fire-once useRef guard.
Left as-is (low value, documented): the Plex image proxy authenticates without a DB
load / epoch check (poster/art fetches only); adding one would cost a DB hit per image.
Two tabs in one browser can now run two different signed-in accounts at once.
- The signed session cookie stays the browser's account WALLET (account_ids). Which account a
given tab acts as is a per-tab choice held in sessionStorage and sent per-request via the
X-Siftlode-Account header; current_user honours it only for an account already in the wallet,
without mutating the cookie's default account. Switching accounts sets the header + reloads
THIS tab only, instead of the old cookie-wide switch that changed every tab.
- WebSocket can't send headers, so the per-tab account rides in the ?account= query param
(validated against the wallet).
- Logout is per-tab aware: it signs the requesting tab's active account out of the wallet
(promoting a new default only if the removed one was the default), and the tab drops its
override. A stale per-tab header account 401s just that tab instead of clearing the session.
- Serve index.html with Cache-Control: no-cache so a deploy's new hashed bundle is picked up
immediately instead of the browser running a heuristically-cached stale index.html.
- quota.measured() context manager folds the before/after units diff that the
manual sync routes each re-spelled (also makes quota_remaining_today consistent).
- sync pause/resume now use Depends(admin_user) instead of inline role checks.
- is_messageable_user() unifies the 'real, active, non-suspended human' rule that
was encoded three ways (WS auth, send recipient, and the SQL _messageable()).
The live-message push now carries both parties, so an incoming message opens
that conversation's dock window if it's closed, or flashes it once if it's
already open (expanded or minimised, without disturbing the minimised state) —
only for messages from someone else, never your own echo.
Dock state (open windows + minimised state) is persisted per user, so a reload
restores exactly what was open, minimised, or closed.
Private user-to-user messages are end-to-end encrypted: the server only ever
stores ciphertext + iv and acts as a key directory (public keys) plus an opaque
store for each user's private key, wrapped client-side with a passphrase the
server never sees — so not even an admin can read a conversation. A separate
kind=system message (plaintext, no sender) powers a server-authored Siftlode
welcome shown on first open, reusable later for announcements.
- models: rework Message (kind, nullable sender/body, ciphertext+iv) + MessageKey;
migrations 0026 (table) + 0027 (E2EE rework).
- routes/messages.py: key directory/blob endpoints, ciphertext send, conversations
+ threads (system + user), lazy welcome, all gated by require_human.
- realtime.py: in-process WebSocket connection registry; /ws delivers sent
messages to a user's open tabs instantly (sync-callable push, single-process).
