docs(openspec): archive fix-install-cancel-method-fallback

[Drswith]

Summary

Archive completed OpenSpec changes fix-install-cancel-method-fallback after their implementation PRs merged, and close the agent-driven archive follow-up with repository validation.

Linked Artifacts

• Issue:
• ADR:
• OpenSpec: fix-install-cancel-method-fallback
• Discussion:

Validation

• bun run openspec:validate
• bun run memory:check
• bun run lint
• bun run format:check
• bun run typecheck
• bun run test (if behavior changed)
• Not run, explained below

Release Intent

• Release: not applicable - OpenSpec archive closure only

Docs Updated

• Not needed
• docs/...
• openspec/...
• Follow-up issue or OpenSpec change created instead

Scope Check

• I did not add a new ad hoc root-level Markdown file.
• I updated the relevant issue, ADR, spec, runbook, or captured the missing doc work as follow-up.
• I did not silently expand project scope without recording it explicitly.

Closure Check

• Working tree was clean before archive closure started.
• Branch was pushed and this PR is the active delivery artifact.
• OpenSpec change is already archived or queued for agent-driven archive closure.
• Release is not applicable, delegated to release automation, or verified.

Notes

• Generated by bun run openspec:archive-closure.
• bun run test was not needed because this PR only archives an already-merged OpenSpec change and does not change product behavior.

Quantex PR Governance — PR #407

Verdict: Blocking — archive move is correct, but OpenSpec archive closure is incomplete without syncing the accepted spec delta into openspec/specs/.

Blocking

Spec delta not merged before archive. This PR only renames the active change into openspec/changes/archive/… (5 files, 0 content edits). openspec/specs/agent-update/spec.md on main still lacks the new scenario from the change delta:

Cancelled managed install does not fall through to later install methods

Per openspec/README.md and prior archive PRs (e.g. #404), archive closure must sync accepted deltas into openspec/specs/ before archiving. Implementation PR #405 correctly kept the delta in the active change only; this follow-up must land it additively under ### Requirement: Managed lifecycle cancellation MUST terminate Windows wrapper process trees before wrapper fallback kill (after the batch-update cancellation scenario).

openspec:validate passing here does not prove sync — it only validates existing specs.

Non-blocking

• Traceability: Link implementation PR #405 in Linked Artifacts for archive follow-up context.
• Validation checklist: Prefer marking only “Not run, explained below” for bun run test (archive-only, no src/ changes) instead of leaving the test box unchecked alongside the explanation.

Passes

• OpenSpec intake (impl): #405 followed intake — proposal/design/spec delta/tasks before code; archive timing after merge is correct.
• Validation surface: openspec:validate, memory:check, lint, format:check, typecheck are appropriate; skipping test is justified.
• PR body / CI: Template structure passes validate-body; release intent “not applicable” is correct (patch already shipped in 0.25.7 via #405); CI matrix and sandbox-tests are green.
• Reviewers: Maintainer-authored archive PR — no additional reviewer request.

Not approving. Please add the additive scenario to openspec/specs/agent-update/spec.md, then re-run bun run openspec:validate before merge.
