B1: `_mark_upload_failed_and_raise` now commits on a separate session
- Helper takes `request + upload_id`, opens a fresh session from
`request.app.state.session_factory` and commits there before raising.
- Closes the named-lock connection-pool leak Codex flagged: the old
"commit-on-the-same-session" implementation could return the
GET_LOCK connection to the pool before the enclosing
`finally: release_named_lock` ran, leaking `mp:<hash>` for up to
`pool_recycle` and re-opening the same-key upload race.
- Same helper now used by `create_server_object_payload`'s put-failure
branch — two failure paths have identical semantics.
B2: streaming copy for soft-delete + restore (`get_stream() + put()`)
- LOCAL backend: zero-copy (aiofiles stream write). OOM fixed.
- S3 backend: still OOMs on multi-GB objects — `put()` materializes
the async iter via `b"".join(chunks)`. Multipart `put` is a
follow-up; do NOT claim "OOM fixed on production" since production
defaults to S3.
C1: worker re-verifies `Users.status='active' AND is_deleted=0`
- `_assert_user_active` called from `_execution_context` after
resolving `triggered_by`; skips `SYSTEM_CRON_USER_ID`.
- `USER_DISABLED` error_code goes into the `NODE_FINISHED_EVENT`
outbox payload — `schedule_node_runs` has no `error_code` column,
the row only carries the `message` text. Docstrings corrected to
say so explicitly (previous docstring falsely promised row-level
observability).
F1: honest browser-local file lock
- `api.ts` `acquireFileLock/heartbeatFileLock/releaseFileLock/
releaseFileLockOnUnload` are now no-ops with comments stating they
never call the network.
- `scriptWorkspaceStore` dropped `tickHeartbeats`; `tickCleanup`
simplified to just clear cache.
- `useEditSessionLifecycle` dropped its 15s heartbeat `setInterval`.
- `ScriptWorkspace.tsx` renders `.local-lock-banner` info bar when
`isEditing`. Two tabs may still silently last-write — banner is the
only guard (acceptable disclosure-only tradeoff).
Dead code: deleted the duplicate `upload_bytes_to_session` in
`backend/src/backend/storage_api.py`. The `services.storage` import
is now the only source of the function; `create_upload_record`'s
docstring updated to point at `backend.resources`.
