Run complete. This is a headless scheduled run with no further action needed — final report below.

Ran a 60-unit singleton batch via two synchronous subagents (25/30 and 27/30 resolved, 34 new companies minted, 8 bonus municipalities harvested from member lists). Population coverage rose 99.78% → 99.86% (residual: 345 → 293 municipalities / 180.6k → 115.9k people; roster now 3,202 companies). Along the way, caught and fixed a pre-existing data bug (two roster-links rows had misassigned AGS 09471152 — Bayern's Lauter — to a Sachsen company; corrected to the real AGS 14521355) and one subagent self-caught a near-duplicate company mint via the mandatory pre-merge domain-collision check. Journal updated with full details; next run should continue singleton batches (271 remain, largest is Talheim at 5,074 people) and the 10-unit multi-member pool stays on hold pending the overdue human decision.

Read CLAUDE.md and journal tail, then SKILL.md in full. Followed the synchronous-shard protocol throughout — no background subagents, no waiting.

State on entry: 3168 roster companies, 99.78% coverage (10598/345 claimed/residual), 323 singletons remaining, 10-unit/22-municipality multi-member pool still on hold pending the overdue human decision (left untouched again, correctly).

Batch build: deleted stale batch60-input.json, regenerated via build_batch60.mjs (60 singleton units). Split 30/30 into dated shard files batch60-shard{A,B}-20260901-1300.json. Max in-use company_id was 19765; assigned shard A wv-de-19800–19849, shard B wv-de-19850–19899 (generous non-overlapping headroom above the last-used id).

Dispatch: two synchronous general-purpose Agent subagents in one message, both run_in_background: false, both carrying the mandatory no-Agent/no-Task-tool line verbatim. Both completed inline (~1350s / ~1638s), neither recursed into background sub-subagents.

Shard A (30 units): 25 resolved, 5 unresolved, 17 new mints (wv-de-19800–19817, one dedup self-caught before writing). Self-caught issue: shard initially re-minted "KWA Meininger Umland" as new before running the mandatory domain-collision check; the check caught the kwa-meiningen.de collision against pre-existing wv-de-635 and the agent fixed it before writing output — exactly the workflow the SKILL.md's last-step recheck exists for. Namesake traps avoided: koenigsfeld.de resolves to the Schwarzwald Königsfeld, not the Mittelsachsen target (left unresolved instead of guessing). Unresolved: Königsfeld (Sachsen), Hasel, Ingenried, Dorfhain, Hartmannsdorf-Reichenau — all with notes on what was checked.

Shard B (30 units): 27 resolved, 3 unresolved, 17 new mints (wv-de-19850–19866). 9 self_supplied, 18 external (9 reused existing companies, 8 new). Namesake traps avoided: sonnen.de (an energy-tech company, not Gemeinde Sonnen) and trogen.ch (Swiss Gemeinde, not Bavaria's). 78.46.40.200 IP-ban pair (fernwasser-franken.de/reckenberg-gruppe.de) avoided via WebSearch snippets and a Landkreis (WWA Ansbach) source instead of direct fetch. Unresolved: Rattiszell, Hopferau, Steinberg — all with notes.

Pre-existing data bug caught and fixed: shard B flagged that roster-links.jsonl already had two rows (Lauter, checked_at 2026-08-27 and 2026-08-30) linking AGS 09471152 to wv-de-3869, a Sachsen/Erzgebirge company — but 09471152 is actually Lauter, Landkreis Bamberg, Bayern (the two rows' own land_hint: "Sachsen" vs city_land: "Bayern" fields already disagreed with each other, a live inconsistency that should have been a standing red flag). Verified against GV100AD: the real AGS for Lauter-Bernsbach, Sachsen (wv-de-3869's actual member, via ZWW's Versorgungsgebiet page) is 14521355. Corrected both existing rows' ags/city_name/ city_land in place and left a note explaining the fix; shard B separately supplied the correct link for the real Bayern AGS (09471152 → wv-de-5029, Veitensteingruppe) in its own output. Worth watching for: any roster-links row where land_hint and city_land disagree is probably the same class of bug — a cheap grep-based sweep for that mismatch across the full file might surface more.

Bonus links harvested: Berg, Kastl (Pettenhofener Gruppe, wv-de-7541), Wirsberg, Dahme, Stadt Gunzenhausen, Heldenstein, Marktl, Haiming — 8 additional municipalities beyond the 60 assigned, claimed via existing companies' member lists.

Validation before merge: both shards well-formed JSONL (17/17 and 17/17 company rows, 33/37 link rows, 0 malformed). All 60 assigned AGS present exactly once across the combined links (60/60, confirmed by direct set-diff against batch60-input.json). 0 cross-shard company_id overlap. Domain-collision recheck (eTLD+1, across every roster.part-*.jsonl + roster.jsonl, 160 files): 30 collisions — none touch this batch's new company_ids (confirmed by explicit check), so this batch introduced none. Note: this is reported as 30 rather than the previously-logged 28; no new run this cycle changed any existing company's domain, so the discrepancy is most likely a prior undercount or a counting-method difference (e.g. some domains have 3+ ids and may have been undercounted as one collision) rather than new drift — worth a future run reconciling the exact method so the number is comparable run over run.

Merge: map_roster.mjs: total links 15369 → 15439 (+70 = 33+37, exact); needs-review queue 1236 → 1531 (growth is from cumulative bonus/name-only rows across this and the prior 10:30 enrich run, not from this batch's AGS-seeded rows, which don't feed the queue). consolidate_roster.mjs: 3168 → 3202 distinct companies (+34 = 17+17, exact). coverage.mjs: municipalities claimed 10598 → 10650 (+52, more than the 60 assigned because bonus-harvest links from member lists claimed additional previously-unclaimed municipalities). Population 99.78% → 99.86% (+0.08pp), residual 345 → 293 municipalities / 180.6k → 115.9k people. build_gv_layer.mjs: multi-member pool unchanged at 10 units/22 municipalities (still on hold), singletons 323 → 271 (-52, exact).

Crossed 99.86% population coverage. Largest unclaimed municipality is now Talheim (5,074, unresolved in a prior run — worth a fresh dedicated look since the pool has shrunk considerably).

For next run: continue singleton batches by residual_population descending — 271 singletons remain. The 10-unit/22-municipality multi-member pool remains on hold pending the overdue human decision — do not spend a run on it without new information. Standing domain-collision backlog now 30 (see note above on the count discrepancy), still awaiting the overdue human consolidation pass, along with the 6 standing duplicate-mint name pairs, the St. Peter/St. Märgen AGS-swap, and the wv-de-10532 hq_ags mismatch flagged in earlier entries (none touched this run). resolve_singleton.mjs's ENOENT dependency on the absent _tasks/netzbetreiber-contact/german- water/ directory presumably still unfixed (not re-checked this run, went straight to WebSearch/WebFetch per the established phase-2b fallback) — now flagged in five consecutive runs, worth an actual fix if a future run has slack. _tasks/netzbetreiber-contact/german-water/ remains absent from this checkout.
