Hook chain repairs (Group A):
- alignment-check.sh: read .prompt (was .user_prompt) — hook was dead
- block-dangerous.sh: jq instead of inline interpreter (RULE 0.2 + fail-open fix)
- destructive-guard.sh: explicit INPUT=cat + jq guard + exit 0 — was silent no-op
- numeric-claims-guard.sh: exit 1 -> exit 2 (Claude Code spec — was non-blocking)
comments updated 0.17 -> 0.18 (env var name kept)
- no-downgrade.sh: removed (?i) PCRE syntax — POSIX ERE matched literal text
- task-timer.sh: jq -nc instead of bare printf — JSON injection on quotes/backslashes
in description was corrupting RULE 0.18 evidence journal
- check-error-patterns.sh: replaced with no-op stub — had hardcoded /Users/denis/...
PATH LEAK in public kit, plus inline interpreter use
- post-commit-audit.sh: added trailing exit 0 — grep return code was hook exit code
- citation-verify.sh: ALLOW_REGEX accepts HOOK-BYPASS marker — bypass was documented
but never matched
- settings-snippet.json: agent-stub-scan moved PreToolUse:Agent -> PostToolUse:Agent
(RULE 0.16 enforcement was firing before transcript existed)
- check-error-patterns hook removed from settings-snippet.json
New defensive hooks (Group H):
- no-github-push.sh: PreToolUse:Bash hard deny on github.com push/create/sync/remote-add
(RULE 0.1 — patent IP protection; was missing from public kit)
- secrets-pre-guard.sh: PreToolUse:Edit|Write — token-pattern scan with allowlist (RULE 0.8)
- chat-numeric-prewarn.sh: UserPromptSubmit reminder when prompt mentions time/cost
(RULE 0.18 chat extension)
- chat-numeric-postflag.sh: Stop event scans last assistant message for naked numerics
without REAL/FROM-JOURNAL/ESTIMATE-HTC markers
Source: full Sonnet test-retest audit 2026-05-02 (3 parallel waves of 6 agents each)
identified hook chain bugs as HIGH severity in all 3 runs independently.

RULE 0.5 NO HALLUCINATION. Prior fabrications (session 68f86858, 2026-04-18):
|
|
• "Alpay-Jorgensen-Levanony 2022 JMP 63:062104" → real is 2026 67:022302 (2 authors)
|
|
• "Jaffe-Jäkel 2014 CMP 325" → real is 3-author Jaffe-Jäkel-Martinez CMP 329
|
|
• "Letac 2023 Lecture Notes" → not in DBLP/arXiv/HAL
|
|
• "Archibald-Kratz-Meerschaert-Sabatelli 2001" → no trace
|
|
|
|
TO PROCEED (any one):
|
|
1) WebFetch/WebSearch the citation → paste DOI/URL as [VERIFIED: <url>] inline
|
|
2) Mark as [UNVERIFIED] and do NOT use as proof
|
|
3) If this is a retraction/audit, include literal: FABRICATED / RETRACTED / MISATTRIBUTED / unverifiable / NOT FOUND
|
|
|
|
Bypass (emergency only): prepend content with "[HOOK-BYPASS: citation-verify <reason>]".
