de:wasserversorger-discover

Ran the wasserversorger-discover skill's freshness check: recomputed coverage.mjs and build_gv_layer.mjs, confirmed no drift and no orphaned shards against the prior run's handoff (80.3% population coverage, 7,082/10,943 municipalities claimed). Phase 2a's pool is confirmed genuinely empty — Bannewitz is the only remaining singleton unit ≥10,000 population and was already exhaustively researched and ruled unresolved in the prior run. Since the skill requires an explicit Frédéric go/no-go before starting phase 2b and this run's trigger carried no such decision, no new discovery batch was run and no roster/link data changed; the go/no-go escalation remains open for a human to resolve.

Triggered via chat (users/108934946863892655718), not the schedule. Read CLAUDE.md and this journal first per the skill's own instructions. Last discovery run (14:12 same day) left PHASE 2A COMPLETE at 80.30% population / 7,082 municipalities claimed, with an explicit instruction to escalate to Frédéric for a go/no-go on phase 2b before any further discovery batches, not to auto-continue.

Re-ran coverage.mjs and build_gv_layer.mjs fresh to check for drift or orphaned shards before deciding anything — matched the 14:12 handoff exactly (80.3%, 7,082 claimed, 3,861 residual). No roster.part-*/roster-links.part-* shard is newer than the consolidated files, so nothing was left unmerged. Queried gemeindeverband-queue.csv directly for singleton units (members_total==1) with residual_population>=10,000: exactly one row, Bannewitz (Sachsen, 11,122) — the same unit already recorded unresolved in the 14:12 entry after an exhausted search (WVW Freital, DREWAG, IWB GmbH, TWF Freital all checked and ruled out, Sachsen's own Trinkwasserversorgungsgebiete registry cross-checked negative). Phase-2a pool is genuinely empty; there is no more phase-2a work to do.

This run's trigger metadata carried no message content indicating Frédéric approved phase 2b — only who requested the run. Per the skill's explicit boundary ("phase 2b is a deliberate decision for Frédéric, not an automatic continuation") and absent any recorded go-ahead, this run did not descend into phase 2b and made no new roster/link claims. This is the same blocker prior runs have raised repeatedly (9+ runs before the 14:12 one); it remains open.

For next run: nothing changed in the roster or coverage this run — it was a read-only freshness check. If Frédéric has given (or gives) an actual go/no-go on phase 2b, record the decision here explicitly (date + who) so future runs stop re-raising it, whichever way it goes. If it's still a no/pending, this same freshness-check-and-stop pattern is correct and cheap. If it's a yes, phase 2b targets ~2,700 small singletons + 673 multi-member units, ~2,041 municipalities / 7.3M people via the multi-member-first ordering already specified in SKILL.md, and the "test for a bulk Kreis-level Gesundheitsamt register before grinding 2,493 units" step should be the very first thing tried.
