fix(hunt): libucl tip OSS build + weekly honesty rollup - #25
Conversation
Tip libucl started pulling CBOR emitter symbols; catalog omitted src/ucl_cbor.c so daily/pack builds failed after clone refresh. Add the unit, a build gate, and export_hunt_weekly_rollup.py for family/signature ledgers without raw-crash hype.

1. Security findings appear as hygiene slots 🐞 Bug ≡ Correctness
info_rows admits every row with a positive family_count, regardless of its verdict, and renders those rows under “INFORMATIONAL slots” without showing the verdict. When a hunt produces a security-class crash, its CVE_CANDIDATE row therefore appears in a section described as hygiene triage rather than being distinguished as a candidate requiring disclosure.
Agent Prompt
## Issue description
The weekly exporter places positive-family security candidates in its INFORMATIONAL section without displaying their verdict.
## Fix Focus Areas
- scripts/ops/export_hunt_weekly_rollup.py[57-71]
- scripts/ops/export_hunt_weekly_rollup.py[128-140]
## Recommended Fix
Filter the informational section to INFORMATIONAL verdicts only. Render other positive-family rows in a separate section that displays their actual verdict, including CVE_CANDIDATE.

2. New security findings get hygiene notes 🐞 Bug ≡ Correctness
hygiene_notes is selected solely by target name whenever that target has families, without checking the finding’s signature or verdict. A new security-class finding on either named target consequently receives a target-level note describing known sanitizer noise, including libucl’s “not bounty” label.
Agent Prompt
## Issue description
The weekly ledger attaches known hygiene notes to every family on a named target, including new security-class findings.

- scripts/ops/export_hunt_weekly_rollup.py[93-97]
- scripts/ops/export_hunt_weekly_rollup.py[120-125]
## Recommended Fix
Associate each hygiene note with the known informational signature or family rather than the target alone. Show the note only when the matching finding is present, and keep candidate verdicts distinct.

3. Partial days look complete in weekly reports 🐞 Bug ◔ Observability
days_present increases for any existing daily rollup, but the weekly exporter never reads that rollup’s slots_done or slots_planned fields. When only some hourly slots ran, the day counts as covered and the weekly headline and verdict totals give no indication that the remaining slots are absent.
Agent Prompt
## Issue description
The weekly report counts a day with any rollup as covered even when its planned hourly slots are missing.
## Fix Focus Areas
- scripts/ops/export_hunt_weekly_rollup.py[44-54]
- scripts/ops/export_hunt_weekly_rollup.py[82-105]
## Recommended Fix
Aggregate each daily rollup's slots_done and slots_planned fields and show completed versus planned slots in WEEKLY.json and WEEKLY.md. Make incomplete days visible alongside the existing day count.

Reject nonpositive window lengths.
If --days is zero or negative, day_ids is empty. Line 73 then raises IndexError instead of reporting an invalid argument. Require --days to be positive before constructing the window.

Restrict informational_slots to INFORMATIONAL verdicts.
If a row has a positive family_count and a different verdict, this condition adds it to informational_slots. The Markdown report then labels that row INFORMATIONAL. Keep family totals independent, but add a row to info_rows only when its verdict is INFORMATIONAL.

Do not report missing data as CLEAN.
If no daily ROLLUP.json exists in the window, fam_by_target is empty and the report says “all CLEAN / no families.” The exporter has no verdict evidence for that claim. Use a distinct message for days_present == 0; reserve a no-families message for windows with available rollups.

Fail the gate when cache removal fails.
If the cache directory does not permit deletion, rm can leave an existing libucl binary in place. The builder can reuse that binary, and the gate can report PASS without testing a fresh link. Remove || true so the gate stops when it cannot clear the cache.
