The Playlist Auto-Sync schedule board was showing "next in 8h" on every
card regardless of the configured interval. Root cause: backend stores
next_run as a naive UTC string ("2026-05-25 05:00:00") and the new
auto-sync renderer was parsing it with plain `new Date(...)`, which
treats unmarked timestamps as local time. On Pacific time that offsets
the displayed countdown by ~8 hours. Auto-Sync now routes through the
existing `_autoParseUTC` helper that the rest of the Automations page
already uses, so countdowns line up with the wall clock.
A separate correctness fix in the automation update API: when a PUT
changes `trigger_type` or `trigger_config`, the stored `next_run` is
now blanked before the engine reschedules. Previously the scheduler's
restart-survival path would preserve a stale future timestamp from the
prior interval, so dragging a playlist from the 8h column to the 1h
column kept firing at the old 8h mark. Boot-time restart behavior is
unchanged — only user-driven schedule changes reset the clock.
Modal restyle: the Auto-Sync manager's hardcoded sky-blue palette is
replaced with `var(--accent-rgb)` everywhere so the modal honors the
user's chosen accent color. Tinted glow on the modal border, tabbed
header active state, scheduled-playlist chips, scrollbars, and a new
drag-over highlight on columns all follow the accent theme. The
column drag-over state is wired through new ondragleave handling so
the highlight clears reliably when leaving a column.
Routes moved to thin parse-args/jsonify handlers; logic now lives in
three focused modules under core/automation/. 436 lines deleted from
web_server.py; 53 added back as wrappers.
Module split:
- core/automation/api.py — CRUD + run + history helpers. Each function
takes (database, automation_engine, ...) explicitly and returns
(response_body, http_status). Includes signal cycle detection
preflight checks for create + update.
- core/automation/progress.py — owns the in-memory progress state dict
+ lock (mirroring the original web_server.py globals as module-level
shared state so all callers see one view), init/update/history
helpers, and the WebSocket emit loop.
- core/automation/signals.py — collect_known_signals for the builder
autocomplete.
Out of scope (deferred):
- _register_automation_handlers — the 23+ action handler closures stay
in web_server.py because each one is tightly coupled to feature-
specific implementations (wishlist, watchlist, library scan, etc.).
- Worker functions (_process_wishlist_automatically, etc.) — belong
with their feature lifts.
- _run_sync_task / _run_playlist_discovery_worker — sync + discovery
PRs.
Behavior preserved 1:1:
- Same route response shapes + status codes
- Same JSON field hydration (trigger_config, action_config,
notify_config, last_result, then_actions)
- Same backward-compat: empty then_actions + notify_type set →
synthesize then_actions from notify_type/notify_config
- Same signal cycle detection behavior on create + update
- Same system-automation protection on delete + duplicate
- Same reschedule/cancel logic on toggle + bulk-toggle + update
- Same progress state shape (status, progress, phase, current_item,
log capped at 50, started_at/finished_at, action_type)
- Same emit-on-finish socketio push from update_progress
- Same emit loop semantics (1s tick, snapshot active states, reap
finished after window)
Pre-existing bugs preserved (will fix in follow-up PRs):
- emit_progress_loop uses naive datetime.now() against tz-aware
started_at/finished_at, so the timeout-zombie check raises
TypeError → caught → never fires, and the cleanup-after-window
check raises → caught → state is reaped on FIRST tick regardless
of the window. Tests document this behavior so the next PR can
flip them to the corrected expectation.
Tests: 72 new under tests/automation/ (signals 10, progress 24,
api 38). Full suite: 861 passing (was 789). Ruff clean.
