cfn-lint, semgrep, and checkov were scanning synthesized/vendored output
(cdk.out, node_modules, .venv/venv, .aws-sam, dist, build). On CDK repos this
explodes the find/xargs arg list and stalls the scan, and flagging synthesized
templates is wrong. Prune those trees in the cfn-lint find, and pass
--exclude / --skip-path to semgrep / checkov.
First-run data (2026-06-17) showed the $20 ceiling covered only the
canary + 5 of ~22 scannable repos before pausing the rotation, leaving
16 repos un-deep-scanned that night. Raise TOTAL_BUDGET_USD default to
$120 so every repo gets a deep agentic pass each night (~22 x ~$5 +
canary, with headroom). Spend draws on the Max subscription pool; the
per-target cap ($12) and round-robin rotation are unchanged, so this is
a ceiling raise, not a per-repo cost change. Updates README, DEPLOY, and
the systemd Environment example to match.
First full VM run: canary recall 18 with the expanded Node/.NET corpus, and a real
agentic repo cost ~$3.50 (vs the $1.4 testbed). Raise CANARY_FLOOR 10->14 (catches a
language-blindness recall collapse to ~9 while keeping margin under 18) and MAX_CYCLE_NIGHTS
4->6 (at ~4-6 agentic repos/night a full 22-repo rotation takes ~4-5 nights; 4 would
false-fire the coverage alarm). Both stay env-overridable and re-tunable as data accrues.
scan_scanners communicates results via globals (T1_BLOCK/T1_CRIT/T1_HIGH); its last
statement was a bare [ $rc -eq 1 ] && T1_BLOCK=1. On a PASS (rc=0) that test is false,
so the function returned non-zero and set -e killed the whole sweep at the first passing
repo in tier 1 (right after the unbound-variable fix let it get that far). Add an explicit
return 0. Audited the rest of the tier1/tier2/summary path; scan_agentic and the others
already end on a zero-status command.
scan_scanners referenced ${slug} inside the SAME local statement that defines it
(local target=... slug=$2 result_json=...${slug}...). bash expands the local's
arguments before the builtin assigns them, so under set -u ${slug} is unbound and
the sweep died right after the canary, before tier 1 ever ran. Split the local so
slug exists first. Fix the same latent self-reference in mirror_repo (dir=...$name),
which only worked by accident because the discovery loop left a global $name.
The live global pre-push hook was hand-edited to resolve suppressions from a
machine-level file (${SH_SECURITY_SUPPRESSIONS_DIR:-~/.config/sea-haven/security-review}/
<repo-basename>/suppressions.json) kept out of repo history, falling back to a
repo-local .security-review/suppressions.json. The repo-sourced hooks lacked it, so
install-hooks.sh --global would overwrite the live hook and lose the feature.
Port the prefer-machine/fallback-repo-local block into hooks/pre-push, align
hooks/pre-commit to the same (else a machine-suppressed finding passes at push but
blocks at commit), and document the path + SH_SECURITY_SUPPRESSIONS_DIR override +
basename-collision caveat in the README.
run_headless.py is the Path B engine the nightly sweep calls: the 6 fresh-context
detectors + proof-or-kill verifier from /sh-security-review, run unattended via the
Claude Agent SDK on subscription OAuth (pops ANTHROPIC_API_KEY so the API key can't
silently win). Read-only tools, hermetic, per-call + total budget caps, fails toward
over-reporting. Emits the finding schema that review.sh --agent-findings consumes.
Rewrite README + DEPLOY-R720 for the clean-clone mirror model, the read-only GH_TOKEN
PAT recipe, the global hook installer, and the no-CI-by-design decision.
Replace the opt-in sweep-targets allowlist with zero-wiring discovery: enumerate org
repos via the GitHub REST API (curl + read-only GH_TOKEN, no gh dependency) and mirror
each as a shallow clean clone (git clone --depth=1, default branch from the API) into
~/repo-mirrors. Scanning server-side clones keeps local .env secrets out of scope.
Tier 1 runs deterministic scanners over every repo nightly ($0 Claude); tier 2 runs the
agentic pass over a budget-bounded round-robin rotation with a persistent cycle pointer,
so the draw on the shared Max limits stays bounded and coverage never goes silently
incomplete (COVERAGE ALARM if the rotation falls behind). Skip = committed marker or
central list (marker-skips logged). Redact secrets from Slack; reports mode 600. Raise
the systemd timeout to 6h for the longer two-tier run.
The global pre-push hook, the /sh-security-review prompt, and finding.schema.json
previously lived only in ~/.config/git and ~/.claude (untracked) — unreproducible.
Source them here: add hooks/pre-push, rewrite install-hooks.sh with a --global mode
(lays down both hooks, sets core.hooksPath, links skill+schema into ~/.claude) and a
per-repo mode. Align pre-commit with pre-push (honor skip marker + suppressions). Add
semgrep p/javascript so the scanners cover the org's Node/.NET repos.
CI was swapped for the global git hooks + nightly VM sweep (solo dev), so
the parked ci/*.yml and CI-BACKSTOP-NOTES.md were dead weight — a defective
workflow in-tree is a foot-gun. Recover from history if the team grows.
Trigger-agnostic pure-code gate that merges deterministic-scanner findings
(semgrep/gitleaks/checkov/cfn-lint/pip-audit) with agent findings from
/sh-security-review, dedups, applies justification-required suppressions, and
makes the block decision (exit 1 on confirmed critical/high). Phase 2 of the
Sea Haven security-review agent; Path B (CI/headless) wiring lands in Phase 3.
