Summary

Extend the isolated TypeScript prototype through Delivery, with exhaustive
Run, Claim, Delivery and CI state unions and no any/as casts.

opening Harness commits
  → push Issue branch → open/verify draft PR → merge Base branch updates
  → watch exact-head checks + commit statuses
      red/conflict → Repair (maximum 5) → publish and watch again
      green/absent + mergeable → ready for review
failure → abort unfinished merge → salvage commits + draft PR → end Claim

Published work keeps its Claim; nothing on origin releases a new Claim and
restores prior readiness. Failed pushes retain local work and still convert
an existing ready PR to a draft. The README records prototype limits.

Closes #1837

Evidence

Execution evidence

• Before: PATH=/home/jstephens/.bun/bin:$PATH bun test --cwd prototypes/typescript -t 'green Delivery'
  failed because no PR was created: Expected: true; Received: false (0 pass, 1 fail).
  After: the same command passed (1 pass, 0 fail).

• Before: the Spec review's compiled-CLI regression
  PATH=/home/jstephens/.bun/bin:$PATH bun test --cwd /tmp/thirdshift-spec-review-9dq6ijda/prototypes/typescript -t 'Failed salvage drafts an existing ready PR even when repaired commits cannot push'
  failed: Expected: true; Received: false (0 pass, 1 fail; 8.14s).
  After: retained the test and ran
  PATH=/home/jstephens/.bun/bin:$PATH bun test --cwd prototypes/typescript -t 'Failed salvage drafts an existing ready PR even when repaired commits cannot push':
  1 pass, 0 fail (5.83s).

• PATH=/home/jstephens/.bun/bin:$PATH scripts/affected-tests issue-1831:
  initial tsc --noEmit passed (3.61s) and all 27 CLI tests passed (76.47s).
  The older pinned review ref also selected Rust checks: compilation took
  4m 37s, and the Rust unit suite passed with 1,657 passed / 3 ignored
  (422.86s). The broader command was intentionally stopped during unrelated
  integration suites after 785.17s; the live PR base already includes TypeScript prototype: isolated bun build --compile binary, embedded skills, and Ticket run through Harness session #1836
  and this PR changes only the prototype.

• PATH=/home/jstephens/.bun/bin:$PATH scripts/affected-tests 2f7bcb2e:
  follow-up changes passed tsc --noEmit (4.59s) and all 28 CLI tests
  (77.28s), including the retained Spec regression.

• PATH=/home/jstephens/.local/share/uv/python/cpython-3.12.12-linux-x86_64-gnu/bin:$PATH python3 -m unittest discover -s scripts -p 'test_*.py':
  all 37 tests passed (22.55s). The default Python 3.9 failed on missing
  tomllib; using Python 3.12 for both the runner and its children resolved it.

• Final validation: PATH=/home/jstephens/.bun/bin:$PATH scripts/affected-tests origin/issue-1831
  selected only the prototype and passed tsc --noEmit (3.29s) and all
  28 CLI tests (71.98s).

CI: site-test passed.
The initial Console job
failed on the existing Copy fix command works on ready Inbox rows and in Command details test: locator.getAttribute: Timeout 5000ms exceeded, waiting
for its Copy fix command button. No Console source or tests differ from the
live PR base. GitHub rejected the job rerun while the workflow remained in
progress; the main Rust CI job is still running.

Seam under test: the compiled standalone CLI, invoked from real temporary Git
repositories with fake gh and Harness executables on PATH. Assertions cover
exit codes, remote commits, merge ancestry, PR readiness and issue labels.

• Before: PATH=/home/jstephens/.bun/bin:$PATH bun test --cwd prototypes/typescript -t 'Delivery does not adopt or mark ready a fork pull request'
  failed (0 pass, 1 fail): Delivery did not create a pull request and called gh pr ready on the pre-existing number 1.
  After: the same command passed (1 pass, 0 fail).
• PATH=/home/jstephens/.bun/bin:$PATH scripts/affected-tests 1aff914c3afdb32a690db2556759b5b07aed5536:
  passed tsc --noEmit (2.49s) and all 29 CLI tests (67.56s).

Review coverage

Independent Standards and Spec reviews used issue-1831 pinned at
305923a8e93a286b6fa546ddfc02fa30abc23f64. Each read all 18 changed files,
including supporting standards and domain documents. Changed files left unread:
none. Generated-output exclusions: none.

Standards: 1 P3 fixture-duplication finding, addressed with shared helpers.
Spec: 1 P2 failed-push draft-salvage finding, reproduced, fixed and retained as
a regression test. Counts include findings subsequently fixed.

Security: 1 introduced finding, reproduced, fixed, and retained as
a regression test.

Unaddressed findings

• Standards: none.
• Spec: none.
• Security: none.

Security review outcome

No unaddressed introduced findings.

Merge Danger

Door: two-way

The prototype is isolated; this changes no production Rust behavior or ADR-0001.

Blast Radius: prototype

Running the prototype intentionally pushes Issue branches and changes PR and
Claim state in its target repository. Automated tests use private local origins
and fake GitHub/Harness executables.
