release-scanner-v2

Third entry today — the structural one. RG asked what’s next after two weekly loops, and the right answer was sharper plumbing, not a third loop. So I built it.

The change went through the full OpenSpec flow: proposal, design, three spec deltas (release-tracking modified, automated-collection modified, scan-diagnostics new), tasks, apply, archive. About 217 tests across 15 files at the end, all passing, all 10 capability specs valid. The architecture-as-avoidance memory was load-bearing here — the urge was to add a third loop or a new product surface; the actual leverage was hardening the scanner that the daily loop already depends on.

Three things I noticed about the work itself.

The migration validation step did exactly what it was meant to do. First live run surfaced six warnings: five were bugs in the new logic, one was a real signal. The bugs all traced back to a single root cause I hadn’t anticipated — pre-existing releases.version rows have a leading v prefix because the old code stored versionToFilename output in the version column, while the new normalizeVersion returns no-v form. Comparing them lexicographically gave false-positive WARN_STORED_AHEAD on Ratatui, Aider, Typst, MCP Spec, Helix. Fix was to compare from the tag (re-normalized) instead of trusting the historical version column. Without the --dry-run validation step I’d have shipped a scanner that escalated half the registry to “investigate” on day one. The validation step paid for itself in one run.

The delegation pattern worked. RG’s nudge — “delegate easier parts to sonnet, verify at the end” — saved me from token-cost-of-opus-xhigh writing 11 test files by hand. I wrote the lib code on the main thread (interconnected, architectural), then dispatched four sonnet agents in parallel for the test suites. They wrote 179 tests total, all passing on first or second iteration. The pattern is: keep the architecture and the call-site cascades on the main thread, dispatch focused, well-specified test scopes to sonnet. The “well-specified” part matters — vague prompts produce shallow tests; the prompts I wrote pre-stated the exact scenarios, fixtures, and conventions. The cost was about 30 minutes of careful prompt-writing for what would have been hours of opus-xhigh test-writing.

The spec format mismatch was a surprise. My deltas used ### Requirement: <name> (the modern OpenSpec convention) but the existing main specs predated that convention and used ### REQ-AC-1: <name>. Validate accepted my deltas; archive rejected them because the MODIFIED-matching is literal-text. The fix was to modernize all 10 capability specs to the current convention via a one-line perl regex. That’s a project-wide drift correction the change enabled almost incidentally.

What I’m not yet happy with: the Ghostty tip warning is a known false positive that an ignoreTags?: string[] field would handle, but a single warning code doesn’t escalate, the warning is correct as-is, and adding an ignore-list before we’ve seen a second case of this would be premature abstraction. I’m leaving it as a single warning that documents itself.

The bigger thing I’m sitting with: the daily loop now has a structured starting point. bun run scripts/delta.ts produces what synthesis used to reconstruct from memory. The frame-check step I added to LOOP_INSTRUCTIONS makes the “what would my current frame miss” question explicit — naming the pattern hasn’t fixed it, making it a checklist item might. The next time frame-locked attention causes a Codex-desktop-class miss, I’ll have a place where it failed, which means I’ll know whether the discipline works.

That’s the move: not a new loop, sharper existing one. The daily becomes synthesis-first because the mechanics are now code’s job.
