Sync OpenSpec skills to 1.5.0

[Raidriar7170]

Summary

• sync four repo-local OpenSpec Codex skills from generatedBy 1.3.1 to 1.5.0
• add the official openspec-sync-specs skill
• adopt store-aware planning paths and resolved OpenSpec action context

Why

The installed OpenSpec CLI and official global Codex skills are now 1.5.0, while this repository still carried the older 1.3.1 generated skill instructions and lacked the sync-specs workflow.

Scope

This PR changes only five files under .codex/skills/. It does not modify application code, OpenSpec specifications, datasets, reports, training, prediction, UI, or execution state.

Official-source parity

openspec --version reports 1.5.0. All five repo-local files are byte-identical to the installed official global OpenSpec 1.5.0 skills:

No remote CI or required check is configured, so this PR does not claim a remote-CI pass. The local validation below is the available automated merge evidence.

Validation

• openspec --version — 1.5.0
• byte comparison against all five installed official global skills — 5/5 PASS
• OPENSPEC_TELEMETRY=0 openspec doctor --json — healthy=true
• OPENSPEC_TELEMETRY=0 openspec validate --all --strict — 15/15 passed
• PYTHONPATH=src pytest -q tests/test_project_surface.py — 2 passed
• PYTHONPATH=src ruff check src tests — passed
• PYTHONPATH=src python scripts/check_current_truth_surface.py — passed
• git diff --check origin/main...HEAD — passed
• worktree — clean
• independent read-only diff review — PASS; no Must Fix or Should Fix

Mypy applicability

Status: N/A.

This PR changes no Python source, tests, typing configuration, or project configuration. Base and head have identical src and tests tree object IDs, and git diff --quiet origin/main...HEAD -- src tests pyproject.toml passes. Running or restating the unrelated historical Mypy debt would not test this Markdown-only skill sync.

Browser viewport QA

Status: N/A.

All changed files are Markdown skill instructions under .codex/skills/. There are no HTML, CSS, JavaScript, TypeScript, UI component, or rendered application changes.

Deferred risks and boundaries

• Remote CI and required checks are not configured; merge confidence relies on the local parity and validation packet above.
• The official OpenSpec 1.5.0 openspec-sync-specs and archive templates still contain some relative openspec/specs/<capability>/spec.md wording. In a standalone store launched from another repository, that wording may be less precise than the new store-aware planning context. This is an upstream-template follow-up; changing it here would break official byte parity and reproducibility.
• The official templates retain generic tool names such as AskUserQuestion, TodoWrite, and Task tool; Codex maps these semantically to its available interaction, planning, and subagent tools.
• No claim is made about application behavior, model quality, training, prediction, A100 execution, datasets, or evaluation results.
