Both line-3 descriptions contained an unquoted ': ' (and '|') that fails
python3 yaml.safe_load ('mapping values are not allowed here'). seo-analyzer's
line was last rewritten by job9/a5a7b54 AFTER job2's F7 strict-YAML rule
(git blame); security-auditor's dates to job6. Single-quote wrap, no internal
apostrophes. Gate: yaml.safe_load over ALL agents/*.md now clean. Review A4.
- README + plugins.lock.json graphifyy note: pipx/PyPI install only, never
npm/npx — a different publisher (rhanka/graphify) squats the same
'graphifyy' name on npm as a version-shadowing shim with its own
conflicting 'graphify' bin (F-X1).
- agents/security-auditor.md: one-line caveat that p/* semgrep packs are
fetched from the registry at runtime — the CLI version pin does not
freeze ruleset content, so a new BLOCK can appear on unchanged code.
MCP magic (F-X3): version pin declined by user call (stays @latest in
lib/toggle-external.sh). ${VAR} env expansion confirmed unsupported at
~/.claude.json user scope (Claude Code docs — expansion is .mcp.json
project-scope only), so the BDR-026 reference-not-plaintext pattern
doesn't transfer here; existing mitigations (canonical ~/.claude/.env,
gitignore, audit env-field filtering) remain the practical ceiling.
~/.claude.json regenerated out-of-repo via toggle-external.sh disable+
enable magic to pick up the already-rotated MAGIC_API_KEY (no repo diff,
no commit for that file — traced in the job6 final report).
agents/security-auditor.md: fresh read-only-on-code SAST gate. Pinned
rulesets p/security-audit + p/secrets + p/owasp-top-ten (owasp REQUIRED —
measured: the 2-ruleset baseline misses SQLi + path-traversal entirely on
realistic Flask code), never --config auto, never auto login (BDR-048).
Severity map: secrets ERROR → CRITICAL, other ERROR → HIGH (block),
WARNING/INFO → reported. gate mode (diff, no Write) vs audit mode (Write
only to REPORT, rule-locked). DEGRADED (semgrep absent) still runs the
checklist and still blocks — never a vacuous pass (LRN-048). Anti-gaming:
a new un-gated nosemgrep suppression is BLOCKING. PROOF mandatory, mute
auditor never a PASS, blind (no iteration history), blocks HIGH/CRITICAL
only (LRN-047).
Grafts: onboard STEP 6 L3a dispatches it in audit mode (report
.onboard-audit/semgrep.md) in BOTH gstack branches — complement to cso
(cso is a gstack submodule, unmodifiable); synthesis picks it up via the
existing .onboard-audit/ sweep. audit-delta security axis runs the SAST
pass first, folds findings into the existing gate/fix/re-verify flow.
lib/tests/security-auditor.test.sh: 28 structure locks green, shellcheck
clean. Behavioral dogfood (fresh agents on a planted fixture):
BLOCK(9) on the vuln commit (2 secrets→CRITICAL, semgrep+checklist
complementarity — checklist caught the 6 semgrep missed off-context);
BLOCK(1) on a new nosemgrep suppression (understood semgrep's 0 was the
mask); DEGRADED → BLOCK(7) on grep-detectable secrets with semgrep hidden.
FP measured on real repos (faunosteo, game): owasp adds only hygiene
findings, contained by diff-scoping.
