geometrybase 078f56998b Backfill IPO price performance history
Request:
- Adjust archivist after the audit findings and update historical data.

Changes:
- Teach the archivist skill to close audit-discovered gaps in priority order.
- Add scripts/archive_price_performance.py for due D1/D5/D20/D60 price-performance backfills.
- Document the price-performance backfill command in README.
- Archive raw Yahoo Finance chart responses under repo-relative data/raw/{ticker}/ paths.
- Populate price_performance with D1/D5/D20/D60 checkpoints and refresh source_refs, sync_runs, sync_tasks, and ticker_sync_state snapshots.

Execution:
- Ran .venv/bin/python scripts/archive_price_performance.py --as-of 2026-06-15T10:00:00Z.
- Selected 291 due price-performance tickers.
- Archived 273 price-history sources and wrote 1063 price-performance rows.
- Re-ran .venv/bin/python scripts/archive_hkex_documents.py --as-of 2026-06-15T10:05:00Z for the remaining open T0/T1 tasks; no additional completed T0/T1 stages resulted.

Verification:
- Compiled the new price-performance script.
- Ran git diff --check.
- Checked SQLite integrity and foreign keys.
- Confirmed database row counts match CSV snapshots.
- Verified all 979 source_refs use valid repo-relative paths, have files, have hashes, and SHA256 hashes match.
- Confirmed no generated Python caches or SQLite transient files remain.

Next useful context:
- price_performance now has 1063 rows: D1 273, D5 272, D20 267, D60 251.
- Remaining due price-performance gaps are 18 tickers where Yahoo history was unavailable or the request failed.
- T0/T1 gaps remain at T0 93 and T1 77; T2 grey-market remains unresolved pending a reproducible source strategy.
