Per 2026-05-03 phase_1_6_bipa_gates scrum (13 findings, 0 convergent).
1 BLOCK verified false positive, 4 real fixes shipped:
False positive (verified):
- opus BLOCK on attest:55 — claimed `set -uo pipefail` without `-e`
makes the post-python3 `if [ $? -ne 0 ]` check unreachable. Verified
WRONG: `X=$(false); echo $?` prints 1. Bash propagates command-
substitution exit through $? on the assignment line. The check IS
the python3 exit gate. Inline comment added to the script noting
the false positive so future scrums don't re-flag.
Real fixes:
1. opus WARN attestation:18 — schema fingerprint hashed names ONLY,
missing column-type changes. A column repurposed to hold base64
photo bytes under its existing name would pass undetected. Now
hashes "name<TAB>type<TAB>nullable=bool" per row. Re-run produced
evidence SHA-256 1fdcc9f1... (vs old 230fffeb..., reflecting the
broader fingerprint scope).
2. opus WARN gate_4_test:60 — definition regex didn't catch
object-literal property forms (`const t = { FEMALE_NAMES: [...] }`)
or TypeScript class fields (`class L { public NAMES_X: string[] = [] }`).
Added two new patterns + a regression test
(Gate 4: object-literal and class-field bypasses are caught) that
exercises 5 bypass forms. 4/4 tests green; 1 minor regex tweak
needed mid-fix to handle single-line class bodies.
3. kimi WARN python3-reliance — script assumed pyarrow installed and
would emit a stack trace into the attestation if not. Added
`python3 -c "import pyarrow"` gate at top with clean install
instructions on failure.
4. opus INFO PHASE_1_6:200 — item 7 (training) silently dropped from
blocking set with bare "deferred" rationale. Now explicitly states
the deferral is conditional on small operator population (J + 1-2
named ops); item 7 re-promotes to blocking if population grows.
⚖ COUNSEL marker added.
Skipped (acceptable as ⚖ COUNSEL placeholders by design):
- kimi WARN consent template:30-day-SLA (counsel decides number)
- kimi WARN consent template:email-placeholder (counsel supplies)
- kimi WARN parquet absence (env override exists; redeployment-aware)
- kimi INFO runbook manual-erasure (marked TODO when /erase ships)
- qwen INFO doc path/status nits (already addressed by file moves)
Tests: 4/4 Gate 4 absence test (incl. new bypass-coverage), 3/3
attestation evidence checks pass on live data.
