All files validated. Final report:

Processed a 45-company batch of German water suppliers (Wasserversorger). Recognizing the batch came from the same WWA Traunstein/Ansbach source range flagged by the prior run as duplicate-mint-prone, I ran a proactive name+AGS dedup check before dispatching research, catching 16 duplicate-mint collisions in ~17 fetches and enriching 14 bonus pre-existing unenriched roster rows for free. The remaining 29 rows went to two parallel research subagents; combined, 28 of 45 batch companies resolved a real domain, pending_domain dropped from 63→19, enrichment.jsonl grew by 59 records (1110→1169), and population coverage held steady at 99.96%. Flagged for a human: a blank-name roster defect (wv-de-20598), a likely stale Achengruppe↔Petting link, and three more twin-mint pairs still domain-less on both sides — all logged in the journal.

Read CLAUDE.md and journal tail, then SKILL.md in full. State on entry: roster.jsonl 3364 rows, 1105 distinct enriched, 99.96% population coverage, 63 pending_domain (all from the 00:30 run's just-cleared batch's leftovers, same wv-de-205xx/206xx WWA Traunstein/Ansbach id range flagged there as a duplicate-mint hotspot).

Batch build: build_enrich_batch_excl.mjs 45 enrich-20260902-0530 — all 45 again pending_domain, again entirely from the flagged id range (this time WWA Traunstein per-Kommune table for Altötting/Berchtesgadener Land/Traunstein, plus a few WWA Ansbach rows). Given the prior run's explicit warning ("worth checking... before it mints more"), ran a proactive dedup check before dispatching any research: a name-similarity script against all roster rows with a resolved domain, plus an AGS-based cross-check against roster-links.jsonl for every batch company's guessed municipality. This surfaced 15 near-certain duplicate mints in the batch itself (exact or near-exact name matches to older, still-unenriched roster rows carrying a resolved domain — e.g. wv-de-20539 "Gemeinde Chieming" vs. pre-existing wv-de-19015, same name, domain chieming.de) plus one already-enriched collision (wv-de-20589 vs. wv-de-5533, both "Jura-Schwarzach-Thalach-Gruppe"). Verified all 15 with one confirmatory Impressum fetch per domain (not assumed from the name match alone), then wrote enrichment records directly — and, since the fetch was already done, also enrichment records for the 13 older sibling company_ids that had a resolved official_domain in the roster but had never been enriched (discovery had set the domain but no enrichment pass had ever touched them) — zero extra fetches, pure bonus coverage. Same treatment for a 16th pair found mid-run: wv-de-20507 ("...Inn-Salzach- Gruppe", roster name corrupted with a stray "|" line-break artifact) turned out to be the same org as pre-existing unenriched wv-de-19864 "Wasserzweckverband Inn-Salzach" — resolved and enriched both. Net: 16 duplicate-collision pairs resolved + 14 bonus companion enrichments from one research pass, using ~17 fetches for 30 enrichment records.

Remaining 29 batch rows dispatched to 2 synchronous general-purpose Agent subagents (15/14 split, both run_in_background: false, both briefed on the duplicate-mint risk and given specific hypotheses to check first: wv-de-20509 Marktl "likely no independent utility", wv-de-20554 Petting "likely just a Surgruppe member", wv-de-20572 Taching a.See "likely = wv-de-7521", the 20561/20103 and 20562/20104 Ettenhausen/Mettenham twin-mint pairs). Both completed inline (~1105s / ~625s). Results were more nuanced than the hypotheses: Marktl turned out to run its own retail/billing operation after all (vg-marktl-stammham.de) despite bulk-buying from Inn-Salzach- Gruppe since 1974 — hypothesis wrong, correctly caught by the subagent rather than rubber-stamped. Petting also turned out genuinely independent (gemeinde-petting.de) — but Achengruppe's own site separately lists Petting as a member municipality, so there may be a stale/wrong Achengruppe↔Petting link in roster-links.jsonl worth a human look. The three twin-mint hypotheses (Ettenhausen, Mettenham, Taching/wv-de-7521) were all confirmed correct, but none had a findable domain on either side, so they stayed pending_domain on both ids — collision recorded, nothing to propagate yet.

Domain resolution across the whole run: 16 dedup collisions + 10 new domains (Erlbach, Winhöring, Harter Gruppe, WBV Obing, Emmerting, Schnaitsee, WBV Oberwössen, Tüßling, Marktl, Reischach) + 2 more new domains (Pleiskirchen, Petting) = 28 of 45 batch rows got a real domain, 17 stayed genuinely pending_domain with an earned reason (small WBVs with no web presence, AlzChem Hart GmbH publishing nothing itself despite being a confirmed real supplier, the blank-name wv-de-20598 defect, Gemeinde Mehring which is supplied by Burgkirchen rather than self-operating, three more twin-mint pairs still domain-less on both sides).

New roster-data defect found: wv-de-20598 has a blank name field in the batch/roster row — the WWA Ansbach per-Ortsteil table read for Landkreis Weißenburg-Gunzenhausen apparently lost track of which entry this was. Unresearchable without a name; needs a human to either re-derive it from the source table or drop the row. Also newly confirmed genuinely distinct (not a triple-mint, despite superficially similar names/shared AGS): wv-de-20515/20516/20517 (Reischach / Wassergemeinschaft Petzlberg / Wasssergemeinschaft Ecking — different addresses/phones in the source table).

Merge: all three shards (enrichment.part-shardA-20260902-0530.jsonl 15, enrichment.part-shardB-20260902-0530.jsonl 14, enrichment.part-main-dedup-20260902-0530.jsonl 30) validated as well-formed JSONL, 59 unique company_ids, zero overlap with each other or with pre-existing enrichment.jsonl, all 45 batch ids covered plus 14 bonus companion ids. Appended directly: enrichment.jsonl 1110 → 1169 lines, 1105 → 1164 distinct company_id (+59). Wrote a matching roster-links.part-main-dedup-20260902-0530.jsonl (55 rows) for the dedup-pass companies' supply areas (subagents wrote their own link shards: shardA 18 rows, shardB 13 rows). Ran map_roster.mjs: roster-links.jsonl 16763 → 16849 rows (+86 exact, matching 18+13+55). Hand-updated official_domain/domain_status: resolved directly on 42 roster.jsonl rows for every record with a non-null analysis.official_domain (28 batch + 14 companion; 3 of the 16 dedup pairs — Grabenstätt's 3-way, JST's single write — share domains so the row count differs from the collision-pair count). coverage.mjs: population 99.96% → 99.96% (unchanged, expected — nearly all resolved companies serve territory already claimed via their duplicate or a sibling). pending_domain in the pending tier: 63 → 19.

For next run: continue by population served — build_enrich_batch_excl.mjs 45 picks up where this run left off; 19 pending_domain rows remain (much smaller than the last two runs' 63/108 — the proactive dedup pass this run cleared a lot of backlog rather than just deferring it). Priority for a human: wv-de-20598's blank-name roster defect (needs the source WWA Ansbach table re-read or the row dropped); possible stale Achengruppe↔Petting link in roster-links.jsonl (Achengruppe's own site lists Petting as a member, but Petting also runs its own gemeinde-petting.de utility — one of these is probably wrong or the split is partial and undocumented); three more twin-mint pairs confirmed but still domain-less on both sides (wv-de-20103/20561 Ettenhausen, wv-de-20104/20562 Mettenham, wv-de-7521/20572 Tachinger WBV) — worth a targeted domain search if a human has time, since resolving one resolves both; wv-de-20586 Alesheim same-name remint of wv-de-5536 (both domain-null, no fix needed yet, just flagged). Standing backlog otherwise: wv-de-20597 (Hesselberg-Gruppe merger) and wv-de-20524 (Bundeswehr site, likely misclassified) from the 00:30 run, 6 pre-existing duplicate-mint pairs (excluded from batches by id), GIPS-platform email cipher (Balingen/Gaggenau/Hemer/Wedel, still uncracked). Process note for future runs: when a batch is entirely sourced from one WWA table/id range that a prior run already flagged as duplicate-mint-prone, doing the name+AGS cross-check before dispatching subagents (rather than leaving it to each subagent to discover independently) paid off this run — caught 16 collisions in ~17 fetches instead of ~2 fetches × 16 companies, and incidentally back-filled 14 old unenriched roster rows for free. SKILL.md's Finish section still names the stale map_ags.mjs/export_csv.mjs pair instead of the live map_roster.mjs + coverage.mjs path — flagged across many consecutive enrich runs now, still unfixed.
