The job +timeout (190 minutes) covers two worst-case waves of each phase plus staging and publication. +Admission refuses a filtered diff larger than 8 batch budgets plus one call limit (928 KiB) +before reading it. The per-batch scope note added to the trusted +prompt contains only fixed text (batch number, rules), never PR file names. Batch 1 holds every file under `.github/`, +`scripts/pr-review/`, `terraform/` (including the edge Lambda), `agent/`, `scripts/v2/agentcore/`, +`scripts/v2/remediation/`, `scripts/v2/secret-rotation/`, `scripts/v2/eks/`, +`scripts/v2/incident/` and `web/app/api/`; worker files whose names start with `remediation`, +`handlers`, `action_catalog`, `connector_target`, `worker_lambda`, `fargate_worker` or `sg_rule` or +contain `dispatcher`; `web/lib/remediation*`, `web/lib/aws*` and `web/middleware*`; plus any file +whose path has a directory or file-name segment starting with iam, polic, auth, guard, +cross_account/cross-account, remediat, admin, connector, mutat, secret, credential, rbac, redact, +frozen, skill, allowlist, assume, writeback or redeploy (at a path, `-`, `_` or `.` boundary). +Classification reads every header path line (old and new ends); quoted, escaped or unparseable +headers count as sensitive. Markdown and unit-test files (`test_*.py`, `*_test.py`, +`*.test.ts[x]`/`.js[x]`) are not counted as permission surfaces. More than one batch of sensitive files is rejected. + +This list prioritizes the main permission surfaces; it does not guarantee that every +security-relevant file is in batch 1. Models see only their own batch's diff and the BASE +checkout. Each batch's input starts with a data header (in the stdin data channel, never the +trusted prompt) listing the sanitized paths changed in the other batches (both ends of renames and copies). A dependency that one of +those paths plausibly provides is reported as an unverified cross-batch dependency; one that no +listed path provides is missing and stays blocking. The note never lowers the severity of a +security finding. Joint review of +changes split across batches is therefore not guaranteed; Merge Verify remains the build and test +check for the whole PR. Every batch receives the PR-wide HEAD image context and must apply the +image-coverage rules to it. + +Each batch writes its own `GITHUB_ENV` flags. `report_invalid`, `chair_input_failed`, +`panel_incomplete` and `image_coverage_failed` block if any batch set them; the comment's +"chair input exceeds allocation" wording then applies to the batch that tripped it. `chair_failed`, which +only selects the "not a code problem" comment wording, is set only when every batch's chair +failed (a batch without the key produced a verdict); a failed chair still fails the gate through +its `VERDICT: FAIL`. When only some chairs failed, `chair_failed_any=1` selects a separate badge +saying review generation failed for one or more batches and the workflow should be re-run, so an +infrastructure failure is never published as a code finding. Scrubbed per-batch chair reports are printed in "Batch review" log groups +with workflow commands suspended, so text cut from an over-limit comment (`comment_bytes`, 60,000) +stays retrievable; each wave logs its batches before its exit status is checked. Batch work +directories, the batch index and the gate's scratch file are removed at the end of every job, and +admission writes batch copies owner-only. The combined +comment has one section per batch, and the PR passes only if +every batch passes. One file over the per-batch budget, or a diff needing more than 8 batches, is +rejected before any model call. A diff within one call's limit keeps the single-review path. Input failures publish a distinct incomplete-input diagnosis; no panel or chair is called. Failed panel coverage skips the chair but publishes fixed diagnostics and unadjudicated severity-keyword presence booleans; it never asserts that the code is safe.
