de:wasserversorger-discover

Run complete. Ran a 60-unit singleton discovery batch for the wasserversorger campaign via two synchronous subagents, resolving 59/60 municipalities (1 honest unresolved: Talheim). Population coverage rose 96.62% → 96.98% (9831→9890 municipalities claimed, residual down to 1053/2.524M people), roster grew to 2745 companies.

Notably, the merge caught 7 genuine duplicate company mints (both shards independently re-minted companies that already existed in the roster from prior runs) via the mandatory cross-shard domain-collision check — fixed by re-pointing links to the pre-existing company IDs before merging, so the standing collision backlog stayed at exactly 27 with none new. Journal updated with details and a new standing recommendation (grep the roster for a name match before minting). The 10-unit multi-member queue and 27-collision backlog remain untouched, still awaiting the overdue human decision/consolidation passes noted in prior runs.

Read CLAUDE.md and journal tail (journal.md is 1MB+/13.4k lines — read only the tail via tail, per standing practice), then SKILL.md in full. On-disk state before starting: 2708 companies, 96.62% population coverage (9831/1112 claimed/residual), 1090 singletons remaining, multi-member pool unchanged at 10 units/22 municipalities, 27 standing domain collisions.

Same-day-unresolved filter applied via a one-off build_batch60_filtered.mjs, deleted after use (fourth run in a row to hand-roll this — build_batch60.mjs still has no built-in flag): all 8 AGS with checked_at:"2026-08-31" and company_id:null in roster-links.jsonl (Schelklingen, Römhild, Weiler-Simmerberg, Berga-Wünschendorf, Gmund a.Tegernsee, Leun, Frankenblick, Grebenstein — the last two newly unresolved by the 03:00 run today) were excluded from the top-60 pull and backfilled from the next-ranked singletons, since today's date hadn't advanced past their checked_at.

Batch: top-60 singletons by residual_population (post-filter), all 1:1 (no multi-member pool units touched — that 10-unit/22-municipality queue is still awaiting the overdue human decision, correctly left alone). Split 30/30, dispatched as two general-purpose Agent subagents, run_in_background: false in a single message (synchronous, per the SKILL banner), mandatory no-Agent-tool line inlined, full method + schema + host-trap list + explicit reuse-before-mint instruction inlined directly in each prompt. Company_id ranges wv-de-18949–18978 (shard A) / wv-de-18979–19008 (shard B), verified against the actual max used ID (18948) before assigning.

Shard A: 30/30 resolved, 29 resolved + 1 unresolved (Talheim/GVV Flein-Talheim — conflicting evidence between a wrongly-scoped flood-protection Verband, a Wasserversorgungsgruppe that explicitly excludes it, and an unverifiable AI-summarized PDF reference; recorded honestly rather than guessed). 19 new companies minted, 10 links reused via existing roster. Non-supplier filter correctly caught an agricultural water-protection body (Niederaula) and a flood-protection Zweckverband (Talheim) as false positives. New host trap: zkd-immenhausen-espenau.de has an expired TLS cert (not down, -k resolves it).

Shard B: 30/30 resolved, 0 unresolved. 25 new companies minted, 5 links reused via existing roster (per the shard's own accounting). Caught several wholesale-vs-retail traps correctly (FWOA at Sulzberg, a Fernwasserversorgung Bayerischer Wald bulk source at Windorf, a technical-operator-only Verband at Fischach, a groundwater-export site at Burgwald, a bulk source at Lohsa) — retail links point to the local self-operating entity in each case, not the bulk supplier. Built a one-off Node zlib/CMap PDF text decoder for a Driedorf Satzung PDF (no pdftotext/python3 in this environment — 8th consecutive discover/enrich run to hit this).

Duplicate-mint bug caught and fixed before merge, not just detected: the mandatory cross-shard-plus-existing-roster domain-collision recompute (run over ALL roster.part-*.jsonl shards — roster.jsonl itself is fully derived from those shards by consolidate_roster.mjs and must NOT also be scanned, or every pre-existing company double-counts against its own shard-of- origin, which inflated a first pass to a bogus "33"/"total 63" collision count before this was understood) found 7 genuine duplicate mints this batch, not just the standing 27: shard A independently re-minted wv-de-18964 for Espenau's supplier when wv-de-18724 (Zweckverband Kommunale Dienste Immenhausen-Espenau) already covered it from a prior run; shard B independently re-minted 6 more (Denkendorf-Kipfenberg, Regensburg-Süd, Wasserzweckverband Freiberg, ZVO/Süsel, Rauher-Berg-Gruppe, WVS Bad Salzungen) all against pre-existing companies from earlier runs — every one an exact-name match on the same domain, not a legitimate one-domain-several-entities case. Fixed by deleting the 7 duplicate roster rows from the shard files and re-pointing the corresponding link rows to the pre-existing company_id (noted in each link's notes) before running map_roster.mjs/consolidate_roster.mjs. Domain-collision check after the fix: exactly 27, matching the standing backlog, none new — confirms the fix was complete and didn't introduce or miss anything.

Merge/finish: map_roster.mjs: 13455 → 13515 roster-links rows (+60, exact), needs-review queue unchanged at 946 (all 60 of this batch's links resolved cleanly via seeded AGS). consolidate_roster.mjs: 2966 shard rows (221 dupes) → 2745 distinct companies (+37 = 44 minted − 7 dedup-fixed, exact). coverage.mjs: municipalities claimed 9831 → 9890 (+59 = 60 dispatched − 1 unresolved, exact), population 96.62% → 96.98% (+0.36pp), residual 1112 → 1053 municipalities / 2.824M → 2.524M people. build_gv_layer.mjs: multi-member pool unchanged at 10 units/22 municipalities, singletons 1090 → 1031 (-59, exact).

Crossed 96.9% population coverage this run — closing in on 97%.

For next run: continue singleton batches by residual_population descending — 1031 singletons remain, largest unchanged at ~6.6k since none of today's 8 same-day-excluded AGS were touched (Schelklingen, Römhild, Weiler-Simmerberg, Berga-Wünschendorf, Gmund a.Tegernsee, Leun, Frankenblick, Grebenstein) — the date has now advanced past their checked_at:"2026-08-31" only if the next run lands after today, so re-include them once that's true. The 10-unit/22-municipality multi-member queue is still awaiting the overdue human decision — do not spend another run on it without new information. Standing 27-domain-collision backlog unchanged, still awaiting the overdue human consolidation pass. New standing recommendation: before minting ANY new company, grep -F the candidate's exact name (or a distinctive fragment) against roster.jsonl first — this run's 7 duplicate mints all had an exact or near-exact name match already in the roster that a simple grep would have caught; the shards' own "check for reuse" instruction wasn't followed consistently enough on regional Zweckverband names that don't obviously look like a nearby-batch neighbor. build_batch60.mjs still has no same-day-exclusion flag — fourth run in a row to hand-roll it, now clearly worth a human fix. resolve_singleton.mjs's missing _tasks dependency remains unaddressed and was not invoked this run (went straight to WebSearch/WebFetch per the skill's phase-2b guidance). SKILL.md's Finish section script names are correct and current — no drift found this run.
