Closes #789


🏷️ PR Type

  • type:feature — New feature

📝 Summary

  • Add a mise.toml at the repo root pinning go = "1.25.10" and node = "24", matching go.mod and publish-pi.yml
  • Add scripts/verify-mise-pins.sh, a CI drift guard that fails closed if any of the 5 authoritative pin sites (mise.toml, go.mod, ci.yml ×2, release.yml, publish-pi.yml) disagree, are missing, or contain an unsupported-format duplicate
  • Wire the guard into ci.yml's unit-tests job (a required check) so drift can't merge silently

📂 Changes

File Change
mise.toml New — [tools] pins for go/node
scripts/verify-mise-pins.sh New, executable — fail-closed pin-drift guard
.github/workflows/ci.yml Added a "Verify mise pins" step in unit-tests, between "Set up Go" and "Run unit tests"

🧪 Test Plan

  • Unit tests pass locally: go test ./...
  • E2E tests pass locally: go test -tags e2e ./internal/server/...
  • Manually tested the affected functionality

./scripts/verify-mise-pins.sh passes clean on this tree (mise pins: go=1.25.10 node=24 agree across go.mod, ci.yml, release.yml, publish-pi.yml and mise.toml) and was verified fail-closed against 5 scratch-copy scenarios: go drift, a deleted go-version: line, a well-formed disagreeing duplicate, a duplicate in an unsupported format (unquoted / ${{ }}) that a naive combined key+value regex would silently miss, and a missing mise.toml.

Two pre-existing local test failures are unrelated to this change — confirmed by reproducing both on a clean upstream/main checkout before this branch existed:

  • internal/setup.TestInstallPiInstallsPackagesAndWritesConfig fails whenever the mise binary happens to be on the test runner's PATH (unrelated to this PR's mise.toml — the code checks PATH, not the presence of a config file). Won't affect CI runners without mise installed.
  • plugin.TestClaudeCodeWindowsPromptResolver* fail under WSL due to a \\wsl.localhost\... UNC path breaking the PowerShell parser — pre-existing WSL/PowerShell interop issue, unrelated to mise.

✅ Contributor Checklist

  • I linked an approved issue above (Closes #N)
  • I added exactly one type:* label to this PR
  • I ran unit tests locally: go test ./...
  • I ran e2e tests locally: go test -tags e2e ./internal/server/...
  • Docs updated (if behavior changed) — docs land in PR 3 of this chain
  • Commits follow conventional commits format
  • No Co-Authored-By trailers in commits

Autonomy

  • CI is expected to pass for this PR branch
  • This PR has one deliverable scope

💬 Notes for Reviewers

Issue #789 needs a status:approved label from a maintainer before the linked-issue check will pass — flagging since I don't have write access to add it myself.

Summary by CodeRabbit

  • New Features

    • Added repository-wide version pins for Go 1.25.10 and Node.js 24.

📝 Walkthrough

Walkthrough

The PR adds Go and Node.js mise pins, a fail-closed validator, and a required CI check. It also adds specifications and planning documents for mise-managed binary detection, update instructions, installation documentation, testing, and rollout.

Scope go and node extraction to the [tools] table.

extract_one applies its grep -E pattern to the entire mise.toml. If [tools].go or [tools].node is absent, a same-named key in another table can satisfy the guard. Track the TOML table before matching these keys, and retain key-first duplicate detection.

Pushed a follow-up commit: aquaproj/aqua-registry#59476 and jdx/mise#12480 shipped in mise v2026.9.0, so the registry short name (engram@latest, and mise upgrade engram) now resolves. Updated the openspec artifacts here (proposal risk/dependency rows, design's decision table and open question, the REQ-MISE-005 normative clause) to match, and marked Phase 2/3 as implemented in the independent sibling PRs #791/#792 (this repo's PRs are independent, not stacked, so this branch never carried that code itself).

271-275: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Align the design example with the fail-closed extraction contract.

The design requires key-only matching, but these extract_one patterns include value syntax. An unsupported duplicate such as one quoted and one unquoted go or node pin can therefore be omitted from the count. Use the broad key patterns from scripts/verify-mise-pins.sh in this example.

Proposed correction
- mise_go_line="$(extract_one "go pin" "${mise_toml}" '^go = "')"
+ mise_go_line="$(extract_one "go pin" "${mise_toml}" '^go[[:space:]]*=')"
...
- mise_node_line="$(extract_one "node pin" "${mise_toml}" '^node = "')"
+ mise_node_line="$(extract_one "node pin" "${mise_toml}" '^node[[:space:]]*=')"

Rebased onto current main (was 399 commits behind).

Dropped the openspec/changes/mise-install-support/** planning artifacts that were carried on this branch: main removed the whole OpenSpec/SDD process directory in #953 on 2026-09-03, so keeping them would reintroduce a directory the maintainers deliberately deleted. This PR now only touches mise.toml, scripts/verify-mise-pins.sh, and .github/workflows/ci.yml, unchanged in substance from before.

./scripts/verify-mise-pins.sh re-verified clean on current main: mise pins: go=1.25.10 node=24 agree across go.mod, ci.yml, release.yml, publish-pi.yml and mise.toml.
