All three are **pre-specify upstream-doc ingestion** commits: each is an ancestor of the specify commit `288607b` (`docs(specify): ingest docs/vision+architecture`). They are the raw upstream `docs/` files being added to the repo *before* the v1.1 CIAgent protocol was applied (the specify commit 288607b is the first v1.1-stage commit and the first to carry a v1.1 `---ci---` block). These three commits belong to the v1.0→v1.1 transition, not the v1.1 milestone proper. They are inside the `v1.1.0..HEAD` audit range only because `v1.1.0` is tagged at the v1.0 Phase 05 traceability commit (58adf9e) — a tag-placement choice that puts the v1.0-complete + audit-v1.0 + docs-ingestion commits inside the v1.1 range. **P1-B (post-hoc, non-blocking):** if the audit protocol requires every commit in the `v1.1.0..HEAD` range to carry a v1.1 ci block, these three pre-specify ingestion commits technically fail it. However: (a) they predate the v1.1 specify stage, (b) the v1.0 milestone-complete commit `80ac975` and the v1.0 audit `d700148` carry v1.0 ci blocks (correct for their milestone), and (c) the v1.0 contracts commit `30e63d6` carries a v1.0 ci block. Only the 3 raw `docs/` ingestion commits lack any ci block at all. Recommended for a future note in the run.md about tag placement (a v1.1.0 tag on the v1.0 *complete* commit rather than the v1.0 Phase 05 traceability commit would have excluded these from the v1.1 range).
