Summary

Close static TypeScript coverage gaps in the onboarding entry-composition ratchet after #9178. The check now records existing lifecycle decisions that the prior scan missed and fails closed when new decisions exceed the merge-base ceiling.

Related Issue

Advances #9172.

Changes

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with doc updates
  • Doc only (prose changes, no code sample modifications)
  • Doc only (includes code sample changes)

Quality Gates

  • Tests added or updated for changed behavior
  • Existing tests cover changed behavior — justification:
  • Tests not applicable — justification:
  • Docs updated for user-facing behavior changes
  • Docs not applicable — justification: This change affects an internal repository check only.
  • Sensitive paths changed (security, policy, credentials, preflight, onboarding, inference, runner, sandbox, or messaging)
  • Sensitive-path review completed or maintainer-approved waiver recorded — reviewer/approval link/justification: Independent Codex Desktop review passed all nine security categories for commit under review 9072818a6220c97bcd02a2b20b0a34915902df6d. The PR-owned files are unchanged by the additive merge of a8ceeb1a6e5ca4e517a4bc0c9767f8a7cc52916d. That merge adds Google Gemini docs and provider-catalog tests outside this check. The review confirmed fixed-argument Git execution, fail-closed merge-base errors, lexical alias isolation, and positive and negative tests.
  • Non-success, skipped, or missing CI check accepted by maintainer — check name, approval link, and follow-up issue:

Documentation Writer Review

  • Documentation writer subagent reviewed the completed changes
  • Result: no-docs-needed
  • Evidence: The PR changes an internal repository check, its allowance data, and tests. The additive merge of a8ceeb1a6e5ca4e517a4bc0c9767f8a7cc52916d changes only Google Gemini docs and provider-catalog tests. The merge does not alter the three PR-owned blobs or their reviewed behavior. This change does not alter runtime, CLI, API, configuration, defaults, policy schema, or supported product behavior. The prior focused tests passed 179/179. I did not rerun them because the PR-owned blobs are unchanged.

  • Normal pre-commit, commit-msg, and pre-push hooks passed, or npm run validate:pr passed after refreshing origin/main when hooks were skipped or unavailable
  • Targeted behavior tests pass for the current change set, or tests are marked not applicable above — command/result or justification: npx vitest run test/onboard-entry-composition.test.ts test/checks-runner.test.ts passed, 179/179 tests.
  • Applicable broad gate passed — npm run check was attempted. Host-specific failures include an unsafe writable parent, a foreign user gateway service, overlong Unix socket paths, and missing plugin-local json5. GitHub CI provides the clean broad result.

📝 Walkthrough

Walkthrough

The onboarding composition checker now analyzes nested callable scopes and broader gateway decision patterns. It validates budget changes against merge-base ceilings. Composition budgets and tests cover gateway, messaging, policy, and provider decisions.

Changes

Onboarding composition analysis

Layer / File(s) Summary
Callable scope discovery
scripts/checks/onboard-entry-composition.mts, test/onboard-entry-composition.test.ts
The checker discovers top-level and nested callable scopes, including functions, methods, accessors, constructors, and nested members. Tests cover gateway decisions across these scopes.
Decision classification and aggregation
scripts/checks/onboard-entry-composition.mts, test/onboard-entry-composition.test.ts
Decision analysis handles lifecycle and recovery names, compound logical assignments, private and computed members, wrapped calls, tagged templates, loop expressions, nested arguments, and pruned callable scopes.
Budget ceilings and validation
scripts/checks/onboard-entry-composition.mts, ci/onboard-entry-composition-budget.json, test/onboard-entry-composition.test.ts
The checker compares declaration, category, and global budgets with merge-base ceilings. Budget allowances and tests cover expanded decision patterns, duplicate allowances, and merge-base failures.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to f4112

This change broadens onboarding composition coverage and enforces a fail-closed decision budget. It is mergeable with owner awareness because duplicated budget values could become inconsistent, and merge-base read failures may provide insufficient diagnostics for timeout or spawn errors.

Give every scope the same shape and drop the in check.

The array mixes one entry that has prunedNodes with entries that do not, so the code recovers the field with a runtime property test. A uniform shape states the intent directly.

Derive the lifecycle and recovery verb lists from one canonical source.

The same verb vocabulary is now spelled out in five regexes: RECOVERY_NAME, RECOVERY_COMPOUND_ACTION, RECOVERY_ACTION_METHOD, and both branches of isGatewayLifecycleIdentifier. If a future change adds a verb to one list only, decision counts shift silently and the budget file absorbs the drift.

Build the alternations from shared arrays so one edit updates every matcher.

Route readBaseFile through the injectable git runner.

resolveCompositionMergeBase accepts a CompositionGitRunner, so tests can drive it without a repository. readBaseFile calls spawnSync directly, so the merge-base loading path cannot be tested the same way. It also duplicates the cwd, encoding, and timeout options already set in runGit.

Pass a runner through mergeBaseCompositionCeiling and reuse it for both calls.

♻️ Proposed refactor
-function mergeBaseCompositionCeiling(): OnboardEntryCompositionCeiling {
-  const revision = resolveCompositionMergeBase();
+function mergeBaseCompositionCeiling(
+  git: CompositionGitRunner = runGit,
+): OnboardEntryCompositionCeiling {
+  const revision = resolveCompositionMergeBase(git);
   function readBaseFile(relativePath: string): string {
-    const source = spawnSync("git", ["show", `${revision}:${relativePath}`], {
-      cwd: REPO_ROOT,
-      encoding: "utf8",
-      timeout: 5_000,
-    });
+    const source = git(["show", `${revision}:${relativePath}`]);
     if (source.status !== 0) {
       throw new Error(`could not read ${relativePath} from merge base ${revision}`);
     }
     return source.stdout;
   }

As per path instructions, guardrails must "Require focused tests for both detection and false-positive behavior"; an injectable runner makes the baseline-load failure path testable.

117-142: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider wrapping the alternation inside alternation.

alternation returns a bare a|b|c. Line 125 uses that value as the whole pattern, so it works today. Every other call site adds (?:...) manually. If a future caller concatenates the result without a group, the alternation will bind more than intended.

Move the group into the helper and remove the duplicated wrappers.

♻️ Proposed refactor
 function alternation(names: readonly string[]): string {
-  return names.join("|");
+  return `(?:${names.join("|")})`;
 }

Then drop the redundant (?:...) at each call site, for example:

-const RECOVERY_FACTORY_NAME = new RegExp(`^(?:${alternation(RECOVERY_FACTORY_NAMES)})`, "i");
+const RECOVERY_FACTORY_NAME = new RegExp(`^${alternation(RECOVERY_FACTORY_NAMES)}`, "i");

Reviewed commit 68f0d2e65a560624d15cc61bf544c54d08a7d354.

I found no remaining correctness defect in the current diff. The latest commit addresses the earlier detector weaknesses: nested callable bodies are counted under stable owners instead of leaking into parents, computed methods receive stable names, recovery/lifecycle vocabulary is canonicalized, and the allowance file is capped against both the merge-base budget and merge-base detector result. The base read and merge-base resolution fail closed, so a PR cannot weaken the ratchet it is being checked by.

This is not an approval because the required CI result for this exact commit is not green. The Pull Request workflow was cancelled, which cancelled all 12 CLI shards, static checks, build/typecheck, and reviewed npm audit; the aggregate cli-tests and checks jobs consequently report failure. Please rerun the required workflows on this commit; if the latest commit stays unchanged and those gates pass, I have no code-review blocker.

Reviewed the latest delta through commit 26aeb9d4b676281119f09e54295ac309343f3c55.

The merge-base diagnostics now distinguish an unavailable Git executable from insufficient fetched history without weakening the fail-closed behavior. Removing case-insensitive matching from the compound recovery pattern also avoids the demonstrated lowercase false positive while preserving the intended camel-case recovery actions. The updated computed-method test now proves the gateway decision is counted under the stable [computed] owner. I found no new code-review blocker in this delta.

This remains a comment, not an approval, while required checks for this exact commit are in progress. If the commit stays unchanged and all required checks pass, I have no remaining code-review blocker.

991-1001: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Include the spawn failure reason in the readBaseFile error.

spawnSync sets error and returns status: null when the spawn fails or the 5-second timeout fires. readBaseFile checks only status !== 0, so the thrown message cannot distinguish "path missing at the merge base", "git timed out", and "git is unavailable". A shallow CI checkout hits this path often.

The earlier fix normalized this in runGit. Apply the same handling here.

🛡️ Proposed fix
     if (source.status !== 0) {
-      throw new Error(`could not read ${relativePath} from merge base ${revision}`);

+          source.error ? ` (${source.error.message})` : ""

Reviewed exact commit 1a785bcfb23691b44248e6aa61ab870760d61fb9. I found no correctness or security defect in the current diff. The checker reads merge-base data through argument-vector Git calls, fails closed on missing history or blobs, enforces declaration/category/global monotonic ceilings, resolves supported lexical aliases and receiver chains, and carries focused edge coverage. The CI repair removes test-body branching without changing behavior. Validation: 179/179 focused tests passed; the composition boundary passed; diff check and conditional scan passed. Security review: secrets PASS; input validation PASS; authentication and authorization N/A; dependencies PASS; error handling PASS; cryptography N/A; configuration and environment PASS; security tests PASS; system security PASS. This is not yet an approval because latest-head CI and the exact merge gate are still running.

Reviewed exact head d6c7480. No blocking findings.

Security review: PASS. The codebase-growth guardrail remains a fail-closed static-analysis and policy surface: Git operations use argv rather than a shell, missing history or blobs fail closed, declarations/categories/global ceilings are monotonic, lexical alias resolution is scope-aware, and the checker does not introduce runtime, credential, network, sandbox, or product activation behavior.

Correctness review: the table-driven fixture preserves all three mocked responses while reducing the onboarding-provider decision count back within the declared ceiling. Focused tests 179/179, the composition boundary, diff check, and conditional scan passed locally. This exact head only adds a merge of current main after the reviewed fix. Approval remains gated on the exact-head documentation receipt and required CI completion.

Reviewed exact head 0f9c6e2. No blocking findings.

Security review: PASS. The codebase-growth guardrail remains fail closed: Git calls use argv, missing history or blobs fail closed, declaration/category/global ceilings are monotonic, and lexical alias resolution remains scope-aware. The latest commit removes an unreachable fallback and does not weaken analysis.

Correctness review: focused checker tests pass 179/179, the composition boundary passes at gateway 5, messaging 16, policy 16, provider 188, and diff check passes. The documentation-writer receipt is exact at 0f9c6e2 with no docs needed. Approval remains gated on required CI completion.

Security review: PASS. The codebase-growth guardrail remains fail closed: Git calls use argv, missing history or blobs fail closed, declaration/category/global ceilings are monotonic, and lexical alias resolution remains scope-aware. The current-main merge leaves every PR-owned checker commit unchanged.

Correctness review: focused checker tests pass 179/179, the composition boundary passes at gateway 5, messaging 16, policy 16, provider 188, and diff check passes. The documentation-writer receipt is exact at 3724542 with no docs needed. Approval remains gated on required CI completion.

Secondary advisor follow-up:

  • The two GITHUB_BASE_REF findings do not apply. runGit calls spawnSync("git", args) without a shell, so punctuation cannot become command syntax. The constructed ref also starts with origin/, so it cannot become a Git option.
  • GITHUB_BASE_REF identifies the PR's target branch in this repository. Reading the merge base against that branch is the intended ratchet behavior. Always using main would compare some PRs with the wrong base.
  • The requested negative tests depend on the injection premise above, so they would not protect a real boundary.
  • The risk-plan warning refers to advisor-generated review metadata, not a repository file changed by this PR.

No code change is needed for these secondary findings. The primary advisor reports no findings, and both advisor jobs passed on head 3724542570cef8f06d2ec68cd7d8698defca7a53.

Reviewed exact head 9072818. The only delta after the prior no-findings review is a merge of current main; the PR-owned composition-boundary changes are unchanged. The checker/runner and composition boundary suites previously passed, the documentation receipt is refreshed to this exact head, and approval remains gated on exact-head CI and the repository gate checker.

Replacement wording for the prior review receipt; this wording supersedes it.
