Good, matches what I wrote (15524, next batch mints from 16001+). The journal entry is accurate. Run complete.

The chat-triggered discovery pass ran a 60-unit phase-2b batch (two synchronous subagent shards, 30 municipalities each), lifting population coverage from 90.57% to 91.49% (9,222/10,943 municipalities claimed, +38 new companies to 2,364 total). The mandatory pre-merge domain-collision check again caught 6 duplicate company mints the shards' own dedup missed (RMG, MAWV, Wasserzweckverband Freiberg, ETW, ZWA-MEV, Grevesmühlen) — fixed by remapping their link rows to the pre-existing IDs before consolidating; results and traps are logged in the journal for the next run.

Triggered via chat (users/108934946863892655718), same trigger source as the 16:07 run just 28 minutes earlier — this run is a second consecutive chat-triggered pass, not a duplicate: on-disk state at start (2326 companies, 90.57%, 9136/10943) exactly matched that run's reported result, so it had genuinely landed before this run began. Read CLAUDE.md and the tail of this journal, then SKILL.md in full.

Batch selection: re-ran coverage.mjs and build_gv_layer.mjs fresh (11 multi-member units / 25 municipalities left, everything else singleton — unchanged from 16:07). Used build_batch60.mjs (not a shell-sort of the CSV — see the 16:07 entry's comma-in-quoted-field trap) to get the next top-60 by residual_population: Gräfenhainichen (11,228) down to Bad Orb (~9,900s at the tail). All 60 had exactly 1 residual member each — phase 2b top tier is pure singleton work, confirmed again.

Dispatch: two synchronous subagents (run_in_background: false, one message, blocked on both), disjoint company_id ranges (A: 15001–15299, B: 15501–15799), mandatory no-Agent-tool line inlined in both (_tasks/netzbetreiber-contact/german-water/ still absent from this checkout). Neither shard recursed. Shard A ~16 min (108 tool uses), shard B ~17 min (137 tool uses).

Shard results: Shard A resolved 30/30 fully, 20 new mints (wv-de-15001–15020, later reduced to 19 — see below), 10 existing companies reused via its own dedup grep (Wittingen→Wasserverband Gifhorn wv-de-1169 yielding 19 bonus Ortsteile, Bannewitz→Weisseritzgruppe wv-de-3211, Osterwieck→TAZV Vorharz wv-de-1126, Schöningen→Avacon Wasser wv-de-3875, Prien a.Chiemsee→Chiemseegruppe wv-de-8556, Boizenburg/Elbe→VersorgungsBetriebe Elbe wv-de-936, Wildau→MAWV wv-de-1517, Ebersbach-Neugersdorf→SOWAG wv-de-5002, Oelsnitz/Erzgeb.→RZV Lugau-Glauchau wv-de-3494, Barmstedt→ pre-existing wv-de-13017). New host trap: rzv-glauchau.de ECONNREFUSED (joins the Cloudflare/403/500 host-trap family). Lorch and Dießen am Ammersee correctly recorded as self-supply (no distinct entity published) rather than guessed. Shard B resolved 30/30 fully, 24 new mints (wv-de-15501–15524, later reduced to 19), 6 existing reused (Büdelsdorf→Stadtwerke Rendsburg wv-de-1139, Schleusingen→ZWAS wv-de-636, Tangerhütte→Wasserverband Stendal-Osterburg wv-de-1129, Querfurt→MIDEWA wv-de-1203, Weil im Schönbuch→Ammertal-Schönbuchgruppe wv-de-1746, Rehburg-Loccum→Wasserverband Nienburger Land wv-de-5001, renamed from "An der Führse" 2025-01-01). ~40 bonus links from member lists (ETW's 33-town area, MAWV's members, ZWA-MEV, Grevesmühlen's 26). Two non-supplier traps correctly avoided: Stadtwerke Olbernhau (no water, ETW is the real supplier) and Abwasserverband Großraum Bad Lauterberg (wastewater-only, Bad Lauterberg Energie is the real one). Host traps: zv-kms.de DNS timeout, dnwab.de 503 — left as flagged gaps rather than guessed. PDF extraction failed on two Satzung PDFs (Büdelsdorf, Gommern) — worked around via secondary sources.

Mandatory domain-collision check, run before consolidate_roster.mjs, across the full existing roster + both new shard files — again caught what the shards' own self-checks missed, third run in a row this has happened: 6 of this run's "new" mints were genuine duplicates of pre-existing companies, on top of the 25 known-benign pre-existing collisions: wv-de-15517 (RMG, dupe of wv-de-1202), wv-de-15518 (MAWV, dupe of wv-de-1517 — the same company shard A correctly reused for Wildau in this same run, so shard B minted a duplicate of a company its sibling shard had just confirmed exists), wv-de-15016 (Wasserzweckverband Freiberg/Sachsen, dupe of wv-de-3176 — same domain, same Land, genuinely the same entity, not the BW Freiberg-am-Neckar near-miss noted in an earlier run), wv-de-15523 (Erzgebirge Trinkwasser GmbH, dupe of wv-de-3857), wv-de-15511 (ZWA Mittleres Erzgebirgsvorland, dupe of wv-de-3957), wv-de-15513 (Zweckverband Grevesmühlen, dupe of wv-de-947). All 6 verified same-domain/same-legal-entity before fixing. Fixed by hand: removed the 6 duplicate roster rows (shard A 20→19, shard B 24→19) and remapped their link rows to the pre-existing company_id (1 remap in shard A, 47 in shard B — the high count in B is legitimate: it's the bonus member-list harvest for ETW/MAWV/ZWA/ Grevesmühlen riding along on the duplicate mint, correctly redirected to the real ID). Re-ran the collision check after the fix: 25 total, unchanged from 16:07, all pre-existing/benign — 0 new collisions once corrected. Take for future runs: a shard's own "grep roster.jsonl before minting" step is not reliable enough on its own — this is now the third run running where the mandatory post-merge re-check caught something both shards' self-report claimed was clean. Do not skip this step or trust a shard's "0 collisions" self-report without independently re-running the check.

Merge: map_roster.mjs: 11199 total link rows (was 11064), 349 needing review (mostly newly-harvested no-AGS names, not a regression). 7 ambiguous entries on inspection — 6 pre-existing (Breitenbrunn, Steinbach, Hausen, Mühlhausen, Weingarten, Papendorf) plus 1 new this run ("Hagen", a bonus Ortsteil of Wittingen harvested via Wasserverband Gifhorn's own page, wv-de-1169 — 2 Gemeinden share the name, correctly left unresolved rather than guessed). consolidate_roster.mjs: 2572 shard rows (208 shard-level dupes) → 2364 distinct companies (+38 from 2326). coverage.mjs: population 90.57% → 91.49% (+0.92pp). Municipalities claimed 9136 → 9222 (+86, more than the 60 dispatched thanks to bonus member-list harvests). Residual: 1807 → 1721 municipalities, 7.878M → 7.112M people. build_gv_layer.mjs: multi-member units unchanged at 11/25 (this batch was singleton work again), singletons 1782 → 1696. By-Land, lowest population coverage: Bayern 77.6% (1345/2217, 10.28M/13.25M), Thüringen 80.6%, Hessen 82.0%, Sachsen-Anhalt 86.2%, Sachsen 86.3% — Bayern remains the biggest lever by a wide margin, unchanged for many runs.

For next run: phase 2b singleton work continues, next top-60 should be re-derived with build_batch60.mjs fresh (do not shell-sort the CSV). Largest still-unclaimed after this run drop below 10k: Tutzing 9,926, Neuried 9,919, Walzbachtal 9,904, Vettweiß 9,903, Waltenhofen 9,901, Rüdesheim am Rhein 9,879, Altenholz 9,865, Südlohn 9,861 — the top-60 tier is thinning, expect the per-batch population yield to keep shrinking as batches move below 10k residents/unit. company_id max on disk now 15524 (sparse: 15001–15019 shard A after the fix, 15501–15524 minus the 6 removed in shard B) — next batch should mint from 16001+. New host traps to add to the known list: rzv-glauchau.de (ECONNREFUSED), zv-kms.de (DNS timeout), dnwab.de (503). Open duplicate-mint/collision list unchanged from prior runs (six entries, see 08-29 13:00 and 15:30 entries) — the overdue human consolidation pass remains the single biggest lever for cleaning up the accumulated review queue, and is now compounding: each run's mandatory collision check is catching new same-run duplicates on top of the old backlog, which is working as designed but means the backlog itself never shrinks without a dedicated pass.
