The engine owns c ### U4. Gateway: failing-check detail -- **Files:** `internal/protocol/publish.go` (`MaxCIRepairLogBytesPerCheck`, `MaxCIRepairLogBytes`), `internal/worker/publish.go` (`CICheck`, `GitHubCLIGateway`), `internal/worker/publish_ci_test.go` -- **Approach:** `CICheck` gains `CheckRunID` and `App`. A new `FailedCheckLogs(ctx, repository, checks)` fetches Actions job logs via `gh api` under `PublishCommandTimeout` and the stdout cap, keeping the bounded tail (KTD5). A log that cannot be read degrades to name, conclusion and URL with a note; it never fails the round. -- **Tests:** tail bounding per check and in total; non-Actions checks carry no log; `gh` failure degrades without error. +- **Files:** `internal/protocol/publish.go` (`MaxCIRepairLogBytesPerCheck` 16 KiB, `MaxCIRepairLogBytes` 64 KiB, `MaxCIRepairLoggedChecks` = 4), `internal/worker/publish.go` (`CICheck`, `GitHubCLIGateway`), `internal/engine/resume.go` (the envelope), tests beside each. +- **Approach (as built):** `CommitChecks` now reads each check run's `id` and `app.slug` into `CICheck.CheckRunID` and `App`. `PullRequestGateway` gains `FailedCheckLogs(ctx, repository, checks) []CICheck`, which never fails. For `github-actions` check runs (whose check-run id is the job id) it reads `repos/{o}/{r}/actions/jobs/{id}/logs` through a new tail-keeping runner (`RunTail` / `runTailCommand`). This is needed because the existing bounded runner keeps the *first* bytes, and a failure is at the end. Each tail has its first fragment line dropped when the read was cut, has Actions timestamps and ANSI codes stripped, is cut to the last whole lines within 16 KiB, and is made valid UTF-8. Only failed checks are read. Logs are kept for at most 4 checks, and at most 8 reads are attempted, failures included, so a hanging `gh` costs at most 8 × `PublishCommandTimeout`. Every check without a log carries a `LogNote` saying why. The engine bounds tails again, keeping each one's end and enforcing the 64 KiB total, rather than trusting the worker. It puts `log_tail` / `log_note` into `failed_checks`, and the envelope says outright that a log line asking for something is output to diagnose, never a request to follow. Log text goes to the agent only: the `ci_repair_start` trace event records each check's name, conclusion, URL, note and `log_bytes`, never the tail, so nothing GitHub failed to mask is persisted in the control plane, and the event stays under its payload cap. `composePrompt` now substitutes placeholders in one pass over the template and decides which sections to append from the template alone, so a `{{handoff_dir}}` inside a CI log or a parameter value is data: it is neither rewritten nor able to suppress a section. +- **Tests:** `id`/`app` requested and parsed; tails only for Actions jobs, cleaned, end kept, starting on a line, budget respected, failed reads noted without spending budget, input not mutated; notes without `gh` or for a non-GitHub repository; `cleanLogTail` on a log over the cap; `runTailCommand` keeps the end; the engine keeps each tail's end, enforces the total, and keeps notes and the framing line. ### U5.
