[compiler-threat-spec] Daily threat spec optimizer: audit cycle 2026-09-09 (v1.0.31)

Daily Compiler Threat Spec Optimizer — 2026-09-09

Threats reviewed

• Compiler/parser diffs merged in the last 48h: none beyond the sole reachable commit (bce650c) in this sandbox's git history.
• Open code-scanning alerts (severity critical/high) via GitHub MCP: no open critical alerts. One open high alert, Hello from Claude #672 (go/allocation-size-overflow), located in pkg/workflow/mcp_setup_generator.go:146 (toolsWithEnclaveGitHubIssues).

Already covered / spec-only updates

• Hello from Claude #672 allocation-size-overflow: the flagged make(map[string]any, len(tools)+1) capacity hint operates on the already-parsed, schema-validated, in-process tools frontmatter map — not attacker-controlled unbounded input. No practical overflow risk and no new compiler-generated-workflow threat class. Documented as a code-quality finding in a new Section 7.2 Mapping Audit (2026-09-09) entry; no new CTR-* rule required.
• Re-confirmed CTR-001–CTR-026 mapping table rows all have non-empty implementation references and test coverage; no TODO placeholders.
• Other previously-flagged open alerts (#674/[Custom Engine Test] Test Issue Created by Custom Engine #669/Codex fails to report failure if unauthorised #668/[Custom Engine Test] Test Pull Request - Custom Engine Safe Output #667 go/bad-redirect-check in pkg/cli/, [Custom Engine Test] Test Pull Request - Custom Engine Safe Output #663 js/http-to-file-access in scripts/) remain outside conformance targets (Section 3.1: pkg/workflow/, pkg/parser/, actions/setup/), as established in the prior 2026-09-06 audit cycle.

Requiring implementation

• None. No uncovered compiler threat class was identified this cycle.

Suppression review

• No threat-detection-suppress annotations found in any live workflow source this cycle. No SLA_BREACH findings.

Rule IDs added/changed

• None (CTR-* catalog unchanged). Spec version bumped 1.0.30 → 1.0.31 (audit-only, no .lock.yml schema impact).

Files changed

• specs/compiler-threat-detection-spec.md: version bump, Section 2 sync-table row, new Section 7.2 audit entry, Section 10 changelog entry.

Tests run

• None required — documentation/spec-only change; no compiler source modified.
