worker_rss_bytes columns + ALTER TABLE migration for existing DBs
- Add cleanup_archive_logs() with configurable ARCHIVE_LOG_DIR/KEEP_COUNT
- Integrate archive cleanup into MetricsHistoryCollector 50-min cycle
Frontend:
- Add slow_query_active and slow_query_waiting StatCards to connection pool
- Add slow_query_active trend line to pool trend chart
- Add Worker memory (RSS MB) trend chart with preprocessing
- Update modernization gate check path to frontend style.css

Three proposals addressing the 2026-02-25 trace pipeline OOM crash (114K CIDs):
1. trace-events-memory-triage: fetchmany iterator (read_sql_df_slow_iter),
admission control (50K CID limit for non-MSD), cache skip for large queries,
early memory release with gc.collect()
2. trace-async-job-queue: RQ-based async jobs for queries >20K CIDs,
separate worker process with isolated memory, frontend polling via
useTraceProgress composable, systemd service + deploy scripts
3. trace-streaming-response: chunked Redis storage (TRACE_STREAM_BATCH_SIZE=5000),
NDJSON stream endpoint (GET /api/trace/job/<id>/stream), frontend
ReadableStream consumer for progressive rendering, backward-compatible
with legacy single-key storage
All three proposals archived. 1101 tests pass, frontend builds clean.

Two changes combined:
1. historical-query-slow-connection: Migrate all historical query pages
to read_sql_df_slow with semaphore concurrency control (max 3),
raise DB slow timeout to 300s, gunicorn timeout to 360s, and
unify frontend timeouts to 360s for all historical pages.
2. hold-resource-history-dataset-cache: Convert hold-history and
resource-history from multi-query to single-query + dataset cache
pattern (L1 ProcessLevelCache + L2 Redis parquet/base64, TTL=900s).
Replace old GET endpoints with POST /query + GET /view two-phase
API. Frontend auto-retries on 410 cache_expired.

Transform /mid-section-defect from TMTT-only backward analysis into a full-line
bidirectional defect traceability center supporting all detection stations.
Key changes:
- Parameterized station detection: any workcenter group as detection station
- Bidirectional tracing: backward (upstream attribution) + forward (downstream reject rates)
- Dual query mode: date range OR LOT/工單/WAFER container-based seed resolution
- Multi-select filters for upstream station, equipment model (RESOURCEFAMILYNAME), and loss reasons
- Progressive 3-stage trace pipeline (seed-resolve → lineage → events) with streaming UI
- Equipment model lookup via resource cache instead of SPECNAME
- Session caching, auto-refresh, searchable MultiSelect with fuzzy matching
- Remove legacy tmtt-defect module (fully superseded)
- Archive openspec change artifacts

Rebuild /admin/performance from Jinja2 to Vue 3 SPA with ECharts, adding
cache telemetry infrastructure, connection pool monitoring, and SQLite-backed
historical metrics collection with trend chart visualization.

- Fix multi-WO display: auto-select all tree roots after resolve so detail
panel loads data for every work order, not just the first seed CID
- Disable scroll-wheel zoom on lineage tree (roam: 'move') to prevent
accidental layout jumps while preserving drag-pan
- Add batch API endpoints (get_lot_history_batch, get_lot_associations_batch)
to avoid N parallel requests hitting rate limits
- Remove redundant Split sub-tab from LOT detail (tree already shows splits)
- Rename 退貨 → 報廢 to match actual reject/scrap data semantics
- Hide internal ID columns (CONTAINERID, EQUIPMENTID, RESOURCEID) from
history table display
- Add timeline scroll container and time range header for long timelines
- Remove obsolete migration and architecture docs no longer needed

Replace the monolithic useQueryToolData composable and nested Vue component tree
with a modular architecture: useLotResolve, useLotLineage, useLotDetail, and
useEquipmentQuery. Introduce ECharts TreeChart (LR orthogonal layout) for lot
lineage visualization with multi-select support, subtree expansion, zoom/pan,
and serial number normalization. Add unified LineageEngine backend with split
descendant traversal and leaf serial number queries. Archive the query-tool-rewrite
openspec change and sync delta specs to main.

SQLAlchemy text() parses :param patterns in SQL comments as bind
parameters. When EventFetcher replaces the WHERE clause via string
substitution, orphaned :container_id in comments causes
"A value is required for bind parameter 'container_id'" errors.
Changes:
- Remove colon prefix from parameter names in SQL comments for
lot_history, lot_rejects, lot_holds, lot_materials
- Archive trace-progressive-ui change (22/22 tasks complete)
- Sync delta specs to main: add trace-staged-api, progressive-trace-ux,
merge api-safety-hygiene (+2 requirements)

Promote /tables, /excel-query, /query-tool, /mid-section-defect from
deferred to full shell-governed in-scope routes with canonical redirects,
content contracts, governance artifacts, and updated CI gates.
Unify all page header gradients to #667eea → #764ba2 and h1 font-size
to 24px for visual consistency across all dashboard pages. Remove
Native Route-View dev annotations from job-query, excel-query, and
query-tool headers.

Convert portal shell from block-centered (max-width 1600px) layout to full-viewport
fluid flexbox with collapsible sidebar: desktop push-mode (240px → 0), mobile overlay
drawer with backdrop. Rename .content → .shell-content to avoid CSS collision with
page-level classes. Override page-level max-width constraints when embedded in shell.
Also replace native <select multiple> in query-tool with shared MultiSelect component
for equipment and workcenter group filters, matching resource-status/history UX.

URL is now single source of truth for filter state (workorder, lotid,
package, type, status) across WIP Overview and Detail pages. Drill-down
carries all filters + status; back button dynamically reflects Detail
changes. Backend Detail API now supports pj_type filter parameter.
Harden concurrency: add pagehide abort for MPA navigation, double-check
locking on Redis JSON parse and snapshot build to prevent thread pool
saturation during rapid page switching. Fix watchdog setsid and PID
discovery. Fix test_realtime_equipment_cache RUNCARDLOTID field mismatch.

New independent report page based on DWH.DW_MES_HOLDRELEASEHISTORY providing
historical hold/release performance analysis. Includes daily trend with Redis
caching, reason Pareto with click-to-filter, duration distribution with
click-to-filter, multi-select record type filter (new/on_hold/released),
workcenter-group mapping via memory cache, and server-side paginated detail
table. All 32 backend tests passing.
