Fix security-scanner and duplicate-detector false positives (revised: addresses #63 review)

[abk1969]

Revised version of #63, closed after the requested-changes review found four merge-blocking scanner regressions. This PR carries the original branch plus five commits addressing every finding, each with regression coverage that reproduces the reviewer's exact repro case. Full suite: 52/52 pass (node --test; 47 at review time + 5 new regression tests).

Review findings → fixes

Finding	Fix	Regression coverage
SQL template injection checked only in the first query/execute/raw call	939161c — replaced the single .match(...) with a global-regex loop over every db call	lib/db.ts fixture now has a safe db.query("SELECT 1") before the vulnerable template-literal query (the reported repro); test verified RED pre-fix
node:child_process no longer detected	a5ffa6a — added (?:node:)? to both the require and from regex alternatives	server/logger.ts fixture exercises import { exec } from "node:child_process" + exec(userInput); acbc828 additionally proves the require("node:child_process") alternative in isolation via an in-memory synthetic-file test (revert-verified RED)
isNonProductionPath(fn.file) disabled structural type:"code" duplicate detection, contradicting the PR body	c50ed30 — removed the guard from the structural codeGroups loop only; the documented name-based fnByName guard is unchanged	Synthetic two-file structural duplicate under tests/ + tools/ paths asserts a type:'code' finding; RED pre-fix
info severity absent from severity sort map and High/Medium/Low UI totals/styles	07b754f — added info:3 to the sort map, an Info totals badge, .security-item.info styling, and an info branch in getSeverityColor	Synthetic three-file ordering test that deterministically failed pre-fix (the undefined rank made the comparator return NaN, leaking scan order)

The behavior of flagging a child_process import without a call is pre-existing and was left unchanged; the blocking defect was the missed node: specifier form.

Hello,
Fable helped me to fix PR#63.
Best regards!

Thanks for revising this and covering the four blockers from #63. I independently reran the branch suite (52/52 pass), and the SQL multi-call, node:child_process, structural-duplicate, and top-level info severity fixes are present.

I found two remaining merge-blocking security regressions:

1. Bare Function(...) construction is no longer detected. JavaScript's Function("...") and new Function("...") are equivalent dynamic-code execution paths, but the new \bnew\s+Function\s*\( check only catches the latter. main currently catches both. Please use an anchored form that handles optional new (for example, \b(?:new\s+)?Function\s*\() and add regression tests proving that Function(...) and new Function(...) are flagged while identifiers such as getFunction(...) are not.

2. The blanket isNonProductionPath suppression hides real security findings in executable repository infrastructure. .github/, .claude/, scripts/, tools/, and tooling/ can contain CI workflows, hooks, deploy scripts, and other executed code. In particular, hardcoded-secret detection should not be disabled solely because of the file path. Please narrow exclusions per rule (tests/fixtures/docs where appropriate), preserve secret detection in executable infrastructure, and add coverage for a real secret under .github/ or a script/hook path.

One smaller completeness issue should also be included in the revision: info findings have their own list color and badge, but the security drill-down still falls through to the blue/low-severity styling. Please give info a consistent drill-down treatment.

The failing Vercel status appears to be fork authorization rather than an application or test failure; it is not the reason for this requested-changes review.

Thanks for the thorough re-review — both regressions and the drill-down gap are fixed and pushed (07b754f..4f723a5). Full suite: 54/54 (47 baseline + 5 from the previous wave + 2 new regression tests). Finding → fix mapping:

Review finding	Fix commit	Regression coverage
Bare Function(...) no longer detected	6d6ab03 — regex widened to \b(?:new\s+)?Function\s*\(	New test asserts Function(src) and new Function(src) are flagged while getFunction(name) is not (verified failing before the fix)
Blanket isNonProductionPath hides secrets in executable infrastructure	0fafa94 — split into per-concern predicates; Hardcoded Secret now uses isSecretScanExemptPath (tests/fixtures/docs only), so .github/, .claude/, scripts/, tools/, tooling/ are scanned again. XSS/shell/command rules keep their existing exclusion	New test asserts a credential under .github/workflows/, .claude/hooks/, and scripts/ is flagged while the same line in docs/*.md stays exempt (verified failing before the fix); existing test-stub exemption test still passes
info drill-down falls through to blue/low styling	0ff7a2e — drill-down header gets the same neutral gray family (rgba(92,92,102,…)) as .security-item.info and getSeverityColor	UI-only, outside the vm-extracted analyzer region (same treatment as the info badge fix in 07b754f)

Also in 4f723a5: README and the design spec updated so the documented exemption semantics match the code (the README previously claimed secrets were excluded in tooling paths).

Understood on the Vercel status being fork authorization, thanks for flagging.

Re-verified the latest revision (4f723a5) independently — all three items from the previous review are correctly addressed:

1. Bare Function(...) detection: the rule now uses \b(?:new\s+)?Function\s*\(, which flags both Function(src) and new Function(src) while still rejecting identifiers like getFunction(name) (the \b cannot fall inside a word). Regression test confirmed present and passing.
2. Per-rule path exclusions: Hardcoded Secret now uses isSecretScanExemptPath (tests/fixtures/docs only), so .github/, .claude/, scripts/, tools/, and tooling/ are scanned again; XSS/command/shell rules keep the broader isNonProductionPath. New test covers a credential under .github/workflows/ and .claude/hooks/ being flagged while docs stay exempt.
3. info drill-down styling: the drill-down header now uses the same neutral gray family (rgba(92,92,102,…)) as the list item and badge, and getSeverityColor returns var(--t3) for info.

Branch suite: 52/52 passing (the "54" count included two manual CLI scripts, codeflow-repo-smoke.mjs and verify-brain-vault.mjs, which aren't part of the automated suite — no tests are missing).

One note: a test-merge with current main initially failed tests/architecture-diagram.test.mjs (2 tests). That was not a defect in this PR — the block-candidate sort on main used priority[a.kind]||12, and shell has priority 0 (falsy), so shell blocks like index.html sorted last and were sliced off once this PR's new fixture files pushed the repo past the 64-block cap. Fixed on main in 6319f44; the merged result now passes the full combined suite 58/58. Merging.
