ScreenTinker 2f7133f8c8 fix(#146) A: non-blocking maintenance — chunked+yield+band-gate all sweeps
The death-spiral amplifier: pruneStatusLog ran a whole-table ROW_NUMBER() sort,
40-48s synchronous on the 1.1M-row incident table, freezing boot -> healthcheck
fail -> restart loop.

- lib/chunked-prune.js: shared chunkedDelete (rowid IN (SELECT ... LIMIT ?) since
  better-sqlite3 has no DELETE...LIMIT) — bounded batch + setImmediate yield between
  batches, optional band-gate. Core invariant: no sync op blocks >~50ms ever.
- pruneStatusLog: rewritten per-device via a loose index-scan seek
  (WHERE device_id > ? ORDER BY device_id LIMIT 1 — O(log n) each), retention +
  newest-cap trimmed in bounded batches, async, re-entrancy-guarded, band-gated on
  the interval / un-gated + fire-and-forget at startup so a bloated table self-heals
  on deploy WITHOUT freezing boot.
- heartbeat.js: maintenance moved off the interval body into async band-gated
  re-entrant runMaintenance(); play_logs + provisioning prunes chunked; offline-marking
  stays synchronous.
- pruneTelemetry: bounded single statement (OFFSET 6000 LIMIT batch), stays sync.
- idx_devices_provisioning so the provisioning prune batch subquery is an index range.

Tests: correctness (per-device cap + retention, independent devices), 300k-row backlog
trims in many batches with max event-loop gap <250ms, band-gate no-op while critical +
startup runs regardless, re-entrancy (concurrent -> once). Existing prune tests updated
to await. Suite 247/247.

activity.js feat(workspaces): rename via switcher dropdown - new PATCH /api/workspaces/:id route, per-row pencil affordance in switcher (visible only when caller can_admin), small rename modal with name + slug fields, validation (name <=80 chars, slug ^[a-z0-9]+(?:-[a-z0-9]+)*$ <=60 chars, blank slug -> NULL), 409 on per-org slug collision. Permission gating via new canAdminWorkspace(db, user, ws) helper in lib/permissions.js - reused-ready for future Phase 3 admin actions. /me query now joins organization_members to compute can_admin per accessible_workspaces entry. Drive-by fixes surfaced: (1) activityLogger method filter was missing PATCH, added; (2) routes that operate on a target workspace by URL param need to stamp req.workspaceId from the param so activityLogger captures the right tenant attribution - documented in the route. Smoke fixture: switcher-test@local.test is workspace_admin of Studio A and workspace_editor of Field Crew (no org_owner) so the can_admin true/false split is exercised in one login. 2026-05-12 11:06:55 -05:00
