Summary

  • Add @laststance/backup: backup <path> copies one file or directory into a registered existing private GitHub clone, commits selected changes, and pushes all pending history on the registered branch. Development uses Bun and TypeScript; the installed CLI runs on Node.js 24+ without Bun or runtime npm dependencies.
  • Provide first-use terminal registration and explicit --repo setup, private repository identity/Actions checks, common-directory locking, complete source preflight, literal streamed staging, byte/type verification, and phase-specific recovery messages. Retain destination-only files and never force-push divergent history.
  • Preserve data through interrupted operations and retries: protect ignored files during fast-forward, handle repeat dangling symlinks and BOM filenames, terminate subprocess descendants, and retain Git executable modes when core.fileMode=false.
  • Match Git for Windows symlink separator storage while preserving literal Unix target text; add recovery assertions and a Unix backslash regression. Git for Windows behavior.
  • Preserve phase/recovery errors if lock cleanup also fails, isolate real-Git test fixture environments, and guard timeout-fixture cleanup against missing markers. Document the trusted Git configuration boundary, CLI aliases, and source-helper symbol references.
  • Include an installed-tarball consumer/restore test, Git integration and failure-path tests, three-OS CI, a tag-gated npm trusted-publishing workflow, and setup/recovery/release documentation. This PR prepares npm version 0.1.0; it does not publish a package.

Test Coverage

Sampled behavior audit: 24/30 paths (80%), target met, 6 residual gap groups. This is an AI-assessed sample, not measured line/branch coverage. Diagram line references are from the audit snapshot before the final executable-mode regression was added.

COVERAGE: 24/30 same sampled behavior paths (80%) | RESIDUAL GAPS: 6 groups
TEST FILES: 3 -> 5 | THIS AUDITOR ADDED: 0 tests
Legend: *** behavior with edge/error assertions; ** successful behavior;
        PARTIAL remains a GAP; ->E2E means CLI/Git integration.

Tests: initial audited suite 3 → 5 test files; final local run 67 passed, 0 failed, 174 assertions. Added regressions for tracked executable-mode preservation/new-file modes and literal Unix symlink targets after the diagram audit. The first Windows CI run exposed link separator differences; the follow-up corrects the Git representation and retains exact regular-file byte validation.

Residual test groups: remaining config file/rename failure variants; clone subdirectories; root/missing/invalid-UTF-8 sources; case/normalization collisions and selected submodules; post-preflight filesystem races; index/HEAD/ancestry concurrency. Unix PTY/permission/process-group cases are skipped on Windows. GitHub API and SSH are stubbed around real local Git repositories; a live private GitHub backup and registry publication are separate verification.

Pre-Landing Review

  • Structured review and testing, maintainability, security, performance, simplification, and Red Team passes completed. Fixed BOM handling and package-test portability/version coupling findings; no remaining confirmed findings.
  • Independent Codex CLI adversarial and structured passes ran with nested reviews explicitly enabled. Fixed ignored-file overwrite during fast-forward, repeat dangling-link failure, incomplete descendant cleanup, and executable-mode handling. Each has a regression test; the final mode fix also received a separate scoped Red Team check.
  • Reviews used independent Codex processes/fresh subagent contexts within the same model family; no cross-model-family review is claimed.
  • CodeRabbit completed a full review of the final commit. Audited all five inline findings and all three review-body findings across both historical reviews: three fixed, five skipped with explicit evidence/reasons (complete dispositions). CodeRabbit withdrew the literal-path finding after the reproducer and resolved its thread; all five inline threads are resolved. The real-review status gate passed. A separate real-terminal/Git check verifies that first-use registration preserves a valid clone directory ending in a space.

Design Review

No frontend files changed — design review skipped.

Eval Results

No prompt-related files changed — evals skipped.

Scope Drift

Scope Check: CLEAN. Implementation follows the accepted CLI and data-preservation contracts.

Plan Completion

  • T1–T9 implementation contracts and significant acceptance tests completed.
  • Exact byte/type checks, fail-closed Actions validation, all-pending-history retries, literal staging, metadata protection, and all six type-conflict transitions.
  • Partial-copy repair/retry, linked-worktree locks, terminal setup/cancellation, config preservation, exact size boundary, 10,000-path streaming, and slow-consumer checks.
  • Installed npm bin performs backup/help/version with a failing Bun shim; documented recovery checks bytes, modes, and symlink types.
  • Planned publish.yml is implemented as release.yml with equivalent release behavior and matching trusted-publisher instructions.
  • Ubuntu/macOS/Windows CI passed for 77d2fa20ff66e3490891a74f30e575cfd03a538d (run).

No repository requirements are deferred. Actual npm publication remains separate.

Verification Results

  • bun run check: typecheck, Node-target build, and 67 passing tests / 174 assertions on macOS.
  • Current-commit GitHub CI: Ubuntu and macOS each 67 passed / 0 failed / 174 assertions; Windows 58 passed / 9 Unix-only skips / 0 failed / 148 assertions (run).
  • Post-merge main at 59ed92c: Ubuntu/macOS/Windows CI passed with the same test counts; the merge tree exactly matches the reviewed PR tree.
  • bun install --frozen-lockfile and actionlint: passed.
  • Real npm pack, isolated install with lifecycle scripts disabled, installed backup bin invoked through offline npm exec with Bun blocked: passed.
  • Private GitHub transport/permissions and npm publication are not claimed as live-tested by local fixtures.

Documentation

  • README.md: documented help/version options and their short aliases, specified Bun 1.4.0 for development, clarified the three-OS CI configuration, and linked the existing changelog.
  • Verified CLI options, the development help command, relative documentation links, and whitespace checks.
  • All shipped CLI capabilities have adequate documentation; no architecture diagram drift or remaining documentation gaps were found.

Test plan

  • Local typecheck, build, Git integration, failure/retry, and installed-consumer tests.
  • Workflow syntax validation.
  • Final-commit CI on Ubuntu, macOS, and Windows.
  • Current-commit CodeRabbit review, complete inline/outside-diff audit, and zero unresolved findings before merge.

281-282: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Wrap each JSON.parse call with context.

MAX_COMMAND_OUTPUT_BYTES is 64 * 1024, so the capture limit is not too small for these calls. If either gh api command returns invalid JSON, JSON.parse can expose a raw SyntaxError. Add context and preserve the original error.

♻️ Proposed refactor
-  const metadata: unknown = JSON.parse(metadataOutput.stdout)
-  const actions: unknown = JSON.parse(actionsOutput.stdout)
+  let metadata: unknown
+  try {
+    metadata = JSON.parse(metadataOutput.stdout)
+  } catch (error) {
+    throw new Error('GitHub returned invalid repository metadata JSON.', {
+      cause: error,

CodeRabbit findings audited against 77d2fa20ff66e3490891a74f30e575cfd03a538d.

The full review on the current commit completed at 2026-09-08 19:50:26 UTC. Its commit status says Review completed, and the resolver check script passed. All three review objects were fetched: both nonempty historical bodies in full, including all collapsed nitpicks, and the empty body belonging to the withdrawal reply (review 5146407374); the earlier five findings remain accounted for below.

Source Severity Disposition Current evidence / reason
Lock cleanup masks the primary error Major FIXED 77d2fa2 preserves the original phase/recovery error and appends cleanup details; cleanup-only failures still fail. Regressions cover both outcomes.
Global/system Git config environment Minor SKIPPED — accepted trust model Git configuration, hooks, authentication, and configured transports are intentionally trusted. Suppressing selected global/system files would alter that contract and can load different hooks/credential settings. Repository/index/object redirects remain excluded. README line 50 now states this boundary explicitly.
Test Git environment isolation Minor FIXED 77d2fa2 aligns fixture repository/index/object/config-injection/pathspec exclusions with the runtime. A real-Git regression proves inherited object-directory settings cannot redirect fixture objects.
Fixture cleanup masks startup failure Minor FIXED 77d2fa2 guards marker reading and process-group cleanup together, accepts only positive integer groups, and never returns from finally. The timeout/descendant regression passes.
Review-body JSON parse context, marker 8712d7642858610f47fbc540 Trivial SKIPPED — low-value diagnostic refinement Malformed API JSON already stops before copying. The backup boundary wraps the failure with its operation phase and preserves the cause (src/backup.ts:224-234). Per-response labels refine diagnostics without changing the failure or data-preservation behavior.
Trim prompted directory input Minor SKIPPED — finding withdrawn Trimming a nonblank path can select a different directory or reject a valid one. A targeted check using the existing real terminal/Git fixtures successfully registered a clone named vault (including its final space), pushed the expected file, and verified that registration retained the space: 1 pass / 2 assertions. Evidence and explanation in the thread. Blank/whitespace-only responses still cancel. CodeRabbit agreed, withdrew the finding, and resolved the thread.
Review-body config temporary-file cleanup, marker 1568aa15fea64dc8ded9c250 Trivial SKIPPED — low-value diagnostic refinement A simultaneous write/rename failure and cleanup failure can replace the underlying diagnostic. Registration still fails visibly in the validating phase before any source copy; atomic replacement preserves the existing registry when writing fails. The existing permission-failure regression verifies preservation. Unlike the repaired backup-lock case, this does not discard the outer phase/recovery message or change stored backup data.
Review-body npm version bootstrap, marker ae75273cfb1455f7b976a5a8 Trivial SKIPPED — verified hosted-runner configuration The configured GitHub-hosted Ubuntu runner with the same Node 24 setup selected npm 11.19.0 in the current CI log, satisfying the documented 11.5.1+ requirement. The official npm trusted-publishing example likewise uses Node 24 with no separate npm install. An additional bootstrap is unnecessary for this verified environment; reassess before release if the runner/runtime selection changes.

Validation on this commit: bun run check passed typecheck, Node build, 67 tests / 174 assertions / 0 failures on macOS. Current-commit CI passed on all three operating systems: Ubuntu/macOS each 67 passed / 174 assertions; Windows 58 passed / 9 Unix-only skips / 148 assertions; all 0 failures. The additional literal-path check above is a separate local verification and is not included in these CI counts.

Retained audit totals: 8 distinct findings: 3 FIXED, 5 SKIPPED with reasons, 0 NOT_FIXED or unaudited. This includes five inline findings and three review-body findings across both full reviews. npm publication and a live private GitHub backup are separate from these local/CI fixtures.

All five inline threads are resolved, including the literal-path finding withdrawn by CodeRabbit. The final merge gate rechecked the current SHA, all CI/status checks, and the complete review/thread history immediately before merge; every gate passed.

PR #1 merged at 2026-09-08 20:02:30 UTC as 59ed92c. The final gate returned exit 0, all five inline threads were resolved, all eight findings had dispositions, and the audited PR HEAD remained 77d2fa2 with MERGEABLE/CLEAN. Local main is synchronized, both feature branch references are deleted, and the merge tree exactly matches the reviewed tree.

Post-merge main CI also passed at 59ed92c: Ubuntu/macOS each 67 pass / 174 assertions; Windows 58 pass / 9 Unix-only skips / 148 assertions; all 0 fail. Local and remote main both point to this merge, the working tree is clean, and the one-time continuation heartbeat is paused. npm has not been published.

93-96: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Do not let temp-file cleanup replace the write error.

After a successful rename, temporaryPath no longer exists, so this rm only matters on the failure path. If writeFile or rename fails and rm then rejects (for example EPERM or EBUSY on Windows), the cleanup rejection propagates and the original cause is lost. This is the same masking pattern already fixed for lock cleanup.

♻️ Proposed change
   try {
     await writeFile(temporaryPath, `${JSON.stringify(config, null, 2)}\n`, {
       flag: 'wx',
       mode: PRIVATE_FILE_MODE,
     })
     await rename(temporaryPath, path)
-  } finally {
-    // Remove only the temporary file belonging to this attempted write.
-    await rm(temporaryPath, { force: true })
-  }
+  } catch (error) {
+    // Remove only the temporary file belonging to this attempted write.

Pin npm to a trusted-publishing-compatible version before publishing.

With check-latest: false, actions/setup-node can select a cached Node 24 release. Node v24.0.0 bundles npm v11.3.0, but trusted publishing requires npm CLI v11.5.1 or later. Install a supported npm version before npm publish.

♻️ Proposed fix
       - run: bun install --frozen-lockfile
+      - name: Use an npm version that supports trusted publishing
+        run: npm install -g npm@11.5.1
       - name: Verify tag matches package version
