Part b of 4 of the hub resync at hub main c175d557 (audit run 2026-11-09T16:23:53Z | hub c175d557 | branch override develop). It replaces #475, which the maintainer chose to split. That PR's Copilot round read 32 of its 50 files and stopped at about 1,840 changed lines, so each part here stays at or below that size. The four parts are #478, #479, #480 and #481.

Every file here is byte-identical to the content #475's head (c1193c97) carried. The skills tree and the whole-file docs are byte-identical to the hub. The AGENTS.md/GOVERNANCE.md verbatim sections were written by the hub's scripts/carry.py. See #475 for the probes run before overwriting and for how the hand-merged files were judged.

Files: .github/skills/comment-and-doc-style/SKILL.md, .github/skills/decision-triage/SKILL.md, .github/skills/drive-pr/SKILL.md, .github/skills/merge-and-release/SKILL.md, .github/skills/session-handoff/SKILL.md

Findings left open by the local review

The local strict review recorded the findings below. Each is a reference into a file another part carries, so it lasts only while this part sits on develop alone. On the combined tree of all four parts, every reference resolves. The four parts merge into develop back to back, with no release dispatched in between, so no released state carries a dangling reference.

• introduced, transient: .github/skills/merge-and-release/SKILL.md:49 - makes a backlog-burndown away-mode run the one standing main-merge grant, and :78 cites backlog-burndown "Away Mode". decision-triage/SKILL.md:12,125,160 and session-handoff/SKILL.md:235,247,264,270 route unattended work the same way. But this branch's develop-version backlog-burndown/SKILL.md:15-17 has no away mode and sends the no-maintainer loop to unattended-handoff, which is still present. So an unattended-handoff run invoked with scope main is refused at the main merge, and its seat is held to session-handoff's attended close order, which now exempts only a backlog-burndown away-mode seat. Transient until a and d merge.
• introduced, transient: .github/skills/drive-pr/SKILL.md:206 - its include key and the :311 cite name pr-review-conduct "Every finding ends in a listed outcome", but this branch's develop-version pr-review-conduct still has "Every finding ends in one of five outcomes". Their outcome 4 also disagrees: drive-pr's carried copy records a deferral by class, while pr-review-conduct says "file the issue first, then reply with its link". So a driver and a reviewer following the two skills dispose of the same deferred finding differently. Transient until a merges.
• introduced, transient: .github/skills/drive-pr/SKILL.md:225 - cites GOVERNANCE.md "Trust Boundaries and Hardening Effort" to decline a hardening finding, but the section is absent from this branch's GOVERNANCE.md and drive-pr does not carry it as an include, so the decline cites a section the repo does not hold. Transient until c merges.

Answering the Copilot round on this head, verdict needs a closer look, (1) item, no counted finding.

No change needed. The verdict names no defect in this part's content. It asks for the combined tree to be verified, and that has been done:

• The local strict review checked all four parts (Carry the Hub's backlog-burndown and pr-review-conduct Skills #478, Carry the Hub's Session, Drive, Merge, Doc-Style, and Decision-Triage Skills #479, Re-vendor the Carried Rules and Docs, and the Skills They Govern, From the Hub #480, Carry the Remaining Skills, Copilot Instructions, and Lint Config From the Hub #481) together. Their change sets partition exactly the path set of Resync the Instruction Set, Skills, and Lint Config With the Hub #475's head c1193c97, with no overlap. Every path is byte-identical to that head. On the combined tree, every include region and every section reference resolves.
• That combined content is the one spec/audit.py --branch resync/hub-2026-11-09 measured at hub c175d557. It closed every instruction-set, skills-tree and lint-config finding.
• The transient cross-part references are listed in this PR's body. The four parts merge into develop back to back, with no release dispatched in between, so no released state carries one.
