Track B, Train 1 (fleet mise floor raise, lockstep with https://github.com/basecamp/shipyard/pull/149): this repo's vendored floor pair — min_version in .mise.toml and mise_min_version in bin/setup — bumped 2026.7.5 → 2026.7.10, a mise containing jdx/mise#11034 (transport-agnostic repo-origin comparison), which Train 2's docker-dev-origin v2 block relies on.

Important

Floor resolved: 2026.7.10 — upstream tagged but never published v2026.7.8–v2026.7.10 (v2026.7.11 is the first published release since 7.7). GitHub releases and brew now carry 2026.7.14, but Arch's extra/mise — the Omarchy suite's only install channel — was built from the unpublished v2026.7.10 tag, so 2026.7.10 is the highest floor every channel satisfies today (ancestry: compare v2026.7.10...95ca0a7b = behind; raise again once Arch catches up). The 7.8→7.14 release/source audit is complete (2026-07-27, tracked in the shipyard PR): no task-output or origin-comparison surface changes; the committed audits now bind to 2026.7.10, and the 2026.8.0 unconditional-precompiled-ruby flip remains ahead of the floor. Gate 3 PASSED 2026-07-27 — installability proven by installation on all four channels (macOS curl one-shot self-updated to 2026.7.15, brew bottle 2026.7.14, Arch pacman extra/mise 2026.7.10-1 = exactly the floor, Ubuntu dpkg→mise.run curl 2026.7.15; evidence in shipyard TRACK_B_DRAFT_EVIDENCE/gate3-*-2026-07-27.log). Merge remains gated on the fleet announcement + train GO, and this PR merges only after the shipyard PR lands.

Operations

Blast radius is pull-time: once this lands, machines below the floor error on every mise invocation in this checkout (shell hook-env, quickhook hooks, editor integration) until upgraded — bin/setup converges them, or one upgrade command per platform. Announce before landing; merge early in a workday.

Evidence

• test/mise-floor-test --ref ×5 (all five app branches): 61/61 — floor declared correctly here, and the vendored floor/upgrade logic remains byte-identical across the fleet at this head.
• bin/audit-fleet-setup --ref ×5: fleet clean (this PR does not touch the vendored docker-dev-origin block).
• CI/container audit: no mise pins or installs in this repo's workflows/Dockerfiles — nothing breaks at merge.

Precompiled-ruby spike (binding evidence, 2026-07-27)

Run with the durable harness (test/ruby-precompiled-spike, shipyard PR) from a clean detached worktree at THIS PR's head, against the published v2026.7.14 macos-arm64 release binary (≥ the 2026.7.10 floor; the floor tag itself has no published binary, and the ruby/bootstrap surface is audit-verified unchanged across 7.8→7.14):

Pull request overview

This PR updates Fizzy’s minimum required mise version (“mise floor”) so developer environments will refuse to run mise below the declared version, in support of fleet-wide tooling requirements.

Changes:

• Bump .mise.toml min_version to a newer mise floor.
• Bump bin/setup’s mise_min_version to match the project floor.
