Replace is_creating mutex with atomic flag and RAII guard to ensure
proper cleanup when acquire() futures are cancelled mid-creation,
preventing permanent deadlock for subsequent callers.
Enhances check recipe to detect when only formatting checks fail while
peers pass, automatically applies formatters, then re-verifies. Supports
both Rust (rustfmt + cargo-check) and web (biome + svelte-check)
domains. Displays results eagerly as checks complete instead of in
original order.
Implements POST /api/timeline endpoint that aggregates enrollment by
subject over 15-minute slots, filtering courses by their actual meeting
times. Includes ISR-style schedule cache with hourly background refresh
using stale-while-revalidate pattern, database indexes for efficient
queries, and frontend refactor to dynamically discover subjects from API.
Subjects now have individually calculated scrape intervals based on their
historical change ratio, consecutive zero-change runs, failure counts, and
the current time of day. This reduces unnecessary scrapes during inactive
periods while maintaining responsiveness during peak hours. Includes four
new admin endpoints for monitoring scraper health and scheduling decisions.
Replace simple auto-matching with scored candidate generation that
considers department overlap, name uniqueness, and rating volume.
Candidates above 0.85 auto-accept; others require admin approval.
Implements a canvas-based timeline view with D3 scales showing class
counts across subjects. Features drag-to-pan, mouse wheel zoom, subject
filtering, hover tooltips, and smooth animations. Timeline auto-follows
current time and supports keyboard navigation.
Add JOB_TIMEOUT constant to fail stuck jobs after 5 minutes, and
LOCK_EXPIRY to reclaim abandoned locks after 10 minutes. Introduce
force_unlock_all to recover orphaned jobs at startup. Fix retry limit
off-by-one error and update deduplication to include locked jobs.
Replaces duplicated dropdown/context menu code with parameterized snippet,
eliminates unsafe type casts, adds error handling for clipboard and API
calls, and improves accessibility annotations.
Replace Previous/Next buttons with 5-slot page navigation centered in
pagination bar. Current page becomes a dropdown trigger allowing direct
page jumps. Side slots animate on page transitions.
