One answer to "what is still open?" across all ISAs

[henrique-franze]

Every ISA already states its open claims, but nothing adds them up. To answer "what is still open across all my work?" I had to walk the MEMORY/WORK folders by hand. IsaFrontier.ts answers "what can I take next?" inside one ISA; WorkReconcile, ISAReconcile and Pulse work.ts don't aggregate open claims.

I built a small read-only tool on 7.40.4 and use it daily:

• It scans ISA.md files under configurable roots (default MEMORY/WORK) and reports, per ISA: open, closed and dropped claims, unchecked ## Remaining Work items, phase, age, and a group label read from a frontmatter field (default project; missing → unlabeled).
• It reuses parseClaims from IsaFrontier.ts instead of a new parser.
• It flags two generic anomalies: phase: complete with open claims, and open work idle for more than N days (default 14).
• It has --json with a stable shape, and 30 tests on synthetic ISAs.

I know #1714 declined an index that scans every ISA, and 8.24 (#2308) is close. Two of its features sit near this: feature 1, "a daily loop measures every target and flags any that nothing is pursuing", and feature 4, "one list shows everything the system is doing and watching". So, before opening a PR, two questions:

1. Do features 1 or 4 also count open claims inside ISAs, not only goal targets? If so, I'll drop this.
2. If not, would you take it as a single small file (CLI + tests), or would you rather port the idea yourself?

The branch is ready either way. Happy to cut it to whatever shape fits.
