fix(update): close the dead end for partially populated glob artifacts

[runsonmypc]

Status

LGTM for final review at 373bb5fd8. The hardening is pushed, and local validation and independent review are complete. GitHub CI and Security runs await maintainer approval for the fork; required checks and human review remain merge gates. This PR is not merged.

What was wrong

/opsx:update refused to create a missing companion file under a glob artifact and redirected the user to /opsx:continue. Once any file matches the glob, status marks the artifact done, so continue never selects it again. Required planning files could become unreachable through either workflow.

How it was fixed

• Let update propose a missing file only for a partially populated glob artifact. Empty ready or blocked artifacts still belong to continue; intentionally skipped artifacts stay untouched.
• Fetch the artifact's instructions and template, applying project context and artifact rules as constraints without copying them into the file.
• Require an unused concrete path matching the schema's output pattern, confined inside changeRoot after resolving linked parent directories. Never write to the glob pattern itself.
• Draft before writing, present each proposed revision, and create files only after confirmation. Immediately before creation, refresh status and instructions and recheck the concrete path; require creation to fail if the target already exists.
• Read current dependency files, stop new creation when a required input is missing, and invoke delegated creators only when they can honor the confirmed path and scope.
• Correct the unarchived workflow spec and user docs to describe the populated-glob exception explicitly. A labeled design correction records why the original continue handoff was unreachable.
• Regenerate the distributed skill and parity hashes. Include a patch changeset.

Replication / proof

• The custom-schema CLI regression demonstrates empty output → ready, one matching output → done, and instructions remaining available while a required companion file is absent. Adding the companion in the fixture preserves the original file and the next-artifact state.
• The skipped-artifact regression checks empty output paths plus the explicit do-not-create warning. The custom-schema fixture also demonstrates that a populated artifact stays done after its required input is removed, while instructions report that dependency missing.
• Four strengthened template cases fail on the original PR head and pass after hardening. Both command and skill delivery are checked, including committed skill parity.
• Full suite: 145 files, 4,232 tests passed on Node 20.19.0. Run with USERPROFILE pointing to an empty test directory and without inherited ZSH/ZSH_CUSTOM; use pnpm test.
• Build, ESLint, TypeScript checks, changeset validation, strict validation of add-update-workflow, and deterministic skill/hash regeneration pass.
• The additional confirmation-order and dependency/delegation assertions fail against 494dcf453 and pass after the final hardening. Two fresh independent reviewers cleared the final design and safety diff.

Notes / nits

This changes workflow guidance, not CLI completion semantics or an automatic file writer. Tests verify the emitted guidance and the CLI contracts it uses; fixture writes do not simulate an agent following instructions.

The host's installed MiniMax skills and inherited Oh My Zsh settings caused unrelated test failures; the Cursor/profile failures also reproduced on unchanged main. Test isolation removes that host state without changing product code. The version-check tests require permission to bind a local HTTP server.

Summary by CodeRabbit

• Bug Fixes

  • /opsx:update can now fill missing files within partially completed artifact patterns.
  • Skipped artifacts remain untouched and are no longer treated as missing.
  • Prevented gaps where /opsx:continue could not recognize eligible incomplete artifacts.

• Improvements

  • New files require confirmation and cannot overwrite existing files or leave the change area.
  • Improved dependency, path, and artifact-status validation.

• Documentation

  • Clarified when to use /opsx:continue, /opsx:apply, and /opsx:archive.

📝 Walkthrough

Walkthrough

The update-change skill and generated workflows now support creating a confirmed concrete file under a partially populated glob artifact. Skipped artifacts remain untouched. Empty ready or blocked artifacts remain deferred to /opsx:continue. Tests and documentation reflect the updated guidance.

Changes

Glob artifact gap handling

Layer / File(s)	Summary
Update workflow guidance skills/openspec-update-change/SKILL.md, src/core/templates/workflows/update-change.ts	The workflows draft edits before writing and permit a confirmed concrete path under a partially populated glob artifact. They use instruction and template, apply context and rules as constraints, reject skipped artifacts, validate dependencies and paths, and defer empty ready or blocked artifacts to /opsx:continue.
Workflow contract and documentation openspec/changes/add-update-workflow/specs/opsx-update-skill/spec.md, openspec/changes/add-update-workflow/design.md, docs/commands.md, docs/opsx.md, .changeset/update-glob-artifact-gap.md	The specification, design, documentation, and changeset describe status-based deferral, guarded companion-file creation, confirmation, path restrictions, overwrite prevention, and follow-up commands.
Template and artifact validation test/core/templates/update-change.test.ts, test/core/templates/skill-templates-parity.test.ts, test/commands/artifact-workflow.test.ts	Tests verify skipped-artifact instructions, glob companion outputs, status transitions, concrete-path rules, dependency checks, reconciliation guidance, and updated template hashes.

Merge Risk: ⚪ Minimal · up to 6c748

The workflow now safely supports confirmed creation of missing companion files under partially populated glob artifacts, with status, dependency, path, and overwrite safeguards. The change is mergeable.

[alfred-openspec]

The partially populated glob case is now reachable without expanding the artifact frontier, and the refreshed dependency, scope, symlink, confirmation, and no-overwrite guardrails address the safety concerns. Approved pending CI.
