Request:
- Summarize recent three-year HK IPO T0.5 coverage and statistics.
Changes:
- Added a Chinese Markdown report that separates true subscription-period T0.5 snapshots from external final public oversubscription history.
- Reported current true T0.5 coverage, active future T0.5 rows, final heat proxy buckets, and top recent high-heat IPOs.
- Documented model implications for short T2/D1 exits and future T0.5 sampling.
Verification:
- Ran git diff --check.
- Reconciled counts against data/hk_ipo.sqlite with read-only SQLite queries.
Next useful context:
- True historical T0.5 coverage is currently zero for listed IPOs in 2023-06-15 to 2026-06-15 because T0.5 snapshots only started on 2026-06-15.
- external_ipo_history.public_oversubscription_times is a post-hoc heat proxy, not an original T0.5 input.
