Name the New Pieces in the Release History

[ptr727]

A pre-release check that found something, rather than a change anyone asked for.

Problem

HISTORY.md's Version 2.0 entry enumerates what this repository became: "the shared fleet rules, a machine-readable spec/, the fleet registry/, per-repo audit reports/, branch rulesets, and the AUDIT.md convergence procedure."

Three things shipped since are peers of the items in that list and appear nowhere in it:

• RESYNC.md, now the third procedure an agent routes between, not a detail of the second
• The host tool contract and its version floors, spec/host-tools.json plus a carried host-tools.json per repository
• The derived detector for files the hub hosts rather than carries, so a retired file is found rather than remembered

Why it was worth catching first

A patch release cut against this entry would have published a changelog whose summary omits the session's main deliverable. A reader asking how a repository resyncs would find an enumeration naming only the procedure that measures.

HISTORY.md is per minor version rather than per patch, so nothing is owed for a routine 2.0.x. What is owed is that the 2.0 summary stay true about what 2.0 contains, and it had stopped being true.

The pattern, third time today

This is the same shape as the spec/ enumerations corrected in #653 and the Repository Layout bullet corrected downstream in Blog: a list that was accurate when written, going stale under a change that never mentioned it, with no gate that reads it.

The recurrence is worth noting on its own. Three instances in one session suggests enumerations are a standing hazard rather than three accidents, and the deletion sweep's new "read the files whose job is to say what the repo holds" (#660) covers deletions only. Additions have no equivalent instruction. Not fixing that here.

Verification

The README.md and HISTORY.md openings must mirror per spec/readme-structure.md, so that was checked rather than assumed: titles match, taglines match, using the audit's own extraction.

Pull request overview

Updates the HISTORY.md release-history summary for Version 2.0 so it remains accurate as the repository’s governance/audit catalog has gained additional peer-level components (procedures, host tooling contract, and hub-hosted-file detection) since the initial 2.0 entry was written.

Changes:

• Expand the Version 2.0 bullet to include STANDUP.md, AUDIT.md, and RESYNC.md as the three core routing procedures.
• Include the host tool contract and version floors (spec/host-tools.json plus per-repo host-tools.json).
• Note the derived detection for hub-hosted (not carried) files so retirements are detected without a manual list.
