Progress entries

2026-07-24 — implementation + PR

• All 10 tasks in tasks.md delivered in one commit (config surface only; slack delivery remains issue-1 task 21).
• Gates: make check fully green — ruff, markdownlint (193 files), ruff format, pyright, validate_config.py (6× VALID across 3 schemas), pytest 257 passed (includes the new scenarios-fallback test). Cross-file $ref probed both ways (valid entry accepted, roles-less entry rejected).
• PR #83 opened against main (GitHub returned 500 on PR creation eight times over ~5 minutes before succeeding; branch push and all other API calls were unaffected).

2026-07-24 — process conflict: spec authored retroactively

• Conflict: the implementation bypassed the Kiro 3-phase spec — no docs/specs/issue-82/ existed when PR #83 opened, despite this change touching sensitivePaths (**/*schema* ⇒ high tier ⇒ full spec required). This is the exact gap issue #73 flagged (the loop's own rules skipped when building the loop).
• Surfaced by: @MadaraUchiha-314 on PR #83 ("Why am I not seeing requirements.md, design.md and other files for this?").
• Resolution: spec set authored retroactively in the same PR, each artifact carrying an explicit provenance note rather than pretending phase order was followed. Requirements/design content transcribes the paper trail that DID happen in the open (issue #82 body, the owner's principles comment, the two design comments, decision-035) — the artifacts were late, not the decisions.
• Next: drive PR #83 review to merge; on merge, advance issue #82's phase label to loop:complete and flip status: complete here.
