Verify and close the host-adopt epic (eve) #628

Child of #626. The close child (eve).

User story

As the owner, I want eve's half of the host-adopt epic merged only after its checks pass with relay's epic head, so that main never holds half of it.

Acceptance criteria

• Offer Adopt on SSH-host rows that relay marks adoptable #627 is merged to epic/626-host-adopt with its review and evidence lines.
• A sync PR from sync/626-main merges main into the epic branch and says Closes #628.
• npx playwright test and the --stack run pass once on the frozen epic head, on a fresh stack built with relay's frozen epic head.
• A Verified: line on this issue names the final epic head.
• test/e2e/relay-pin.json names relay's epic head, never relay main.
• merge-check passes on the epic PR to main, and eve merges minutes after relay.

What I'd notice

Nothing new. The change appears on main in one step.

Close lines (eve)

1. The verification task runs once, on the epic head frozen by line 4: npx playwright test, then stack-up on that head and the --stack run, then stack-down. Eve: a fresh stack per run. This issue gets the Verified: line.
2. A push after line 1 means line 1 runs again on the new head. Nothing is planned to push after line 4.
3. Every child is merged to the epic branch, with review and evidence lines in place.
4. main is merged into the epic branch by a sync PR whose head is sync/626-main and whose body says Closes #628. Conflicts are resolved on it.
5. Close Offer Adopt on SSH-host rows that relay marks adoptable #627 with a comment naming its PRs.
6. merge-check passes on the epic PR to main.
7. Merge under the joint close task on Epic: adopt an outside Claude session on an SSH host relay#588 (step c), after relay. Confirm main green, close Epic (eve track): offer Adopt on terminal Claude rows on SSH hosts #626 (step d), delete the epic branch.
8. The run report's final body (run-report finish, by the coordinator).

Verification task

On the devbox, once, on the frozen epic head after line 4, as step b of the joint close task, after relay's run. No devlock. Never kill or replace the devbox's default tmux server.

• repo-suite: npx playwright test.
• devboxverify: a fresh stack-up e628 --relay <relay checkout at its epic head> --eve <eve checkout at the epic head>, node devboxverify/main.js --checkout <eve checkout> --stack <stack.json>, stack-down e628 (also on a failure).
• real-app: the shared devbox pass on Verify and close the host-adopt epic (relay) relay#590 covers eve's screens (Adopt on a host row, the managed host row, the Chief of Staff send, drop in, Interrupt and adopt, the host_link_lost toast). Name its log here.
• Post Verified: <head sha> · repo-suite: <result> · devboxverify: <result> · real-app: <result> · log: <link or path> here.

Tasks

• Open eve's draft epic PR (epic/626-host-adopt to main, body Closes #628) when Offer Adopt on SSH-host rows that relay marks adoptable #627's first PR merges.
• Line 3. Only if relay's epic head moved after Offer Adopt on SSH-host rows that relay marks adoptable #627's pin (relay's sync PR): a pin-only PR chore/628-relay-pin naming relay's final epic head, Closes #628, before the sync PR.
• Line 4, then report lines 3 and 4 on Epic: adopt an outside Claude session on an SSH host relay#588 (joint close step a).
• Line 1 under joint close step b; lines 5 to 8 under steps c and d. Merges happen on the devbox, never on the Mac.

Contract

This child adds no code. Its PRs are the sync PR, a possible pin-only PR, and eve's epic PR to main (Closes #628). merge-check judges them on the files that differ from main, so the list below is every file of #627, written out. Conflict resolution stays inside it.

File ownership

• test/e2e/relay-pin.json (in the pin-only PR, and as Offer Adopt on SSH-host rows that relay marks adoptable #627 left it)
• public/agent-board.js
• docs/FEATURES.md
• docs/api.md
• docs/design-chief-of-staff.md
• test/e2e/g6-outside-adopt.spec.js
• devboxverify/journeys-cos-outside.js
• devboxverify/journeys.js (the one run-list line Offer Adopt on SSH-host rows that relay marks adoptable #627 adds)
• devboxverify/README.md
• test/static/frozen.json

Test surface

The whole Playwright suite and every journey of the --stack run, not a selection, once on the frozen head. outside-adopt-host is a screen journey, so the --stack run skips it and the nightly runs it. Nothing new is written here.

Waits:

• Merges and child state: merge-check exit codes and gh issue and PR state.
• stack-up: its process exit and a valid stack.json; stack-down: its process exit.
• Playwright and devboxverify: their process exits. They hold the browser-test lock; no hand-rolled wait for it.

Budget

0 lines of new code. Conflict resolution only inside the files above; anything else stops and asks.

Amendment 1 (2026-10-22): the ownership list adds devboxverify/journeys.js, to match #627 Amendment 1.
