Ran phase-2a batch 11 (60 singleton municipalities, Sandhausen→Cremlingen), split across 2 synchronous shards — both self-caught and fixed their own duplicate mints, and the mandatory post-merge domain-collision check across all 50 roster shards confirmed zero new collisions (only the 2 pre-existing accepted ones). Population coverage rose 70.65% → 71.99% (+1.34pp), municipalities claimed 6,422 → 6,517, roster now 1,112 companies; phase-2a pool is down to 128 units (1.44M people, ~2 more batches to exhaust). Journal entry appended with full handoff for the next run.

Triggered via chat (not the schedule) by users/108934946863892655718. Continued phase-2a from the 08:00 run's exact handoff (verified pool: 195 units / 2.36M people, next-up list matched exactly — Sandhausen down to Cremlingen). resolve_singleton.mjs was not retried (still reported broken across 4+ prior runs); both subagents researched directly via WebSearch/WebFetch per the skill's "Per municipality" method.

Took the next 60 singleton units by residual_population descending, 15,330 (Sandhausen) down to 12,907 (Cremlingen). Split 2 SYNCHRONOUS subagents (p2t / p2u, 30 cities each), each launched with run_in_background: false and the exact required line ("You may not use the Agent/Task tool...do not end your turn until output files exist"). Both finished cleanly on the first try — no delegation, no background children — 9th consecutive batch confirming the fix holds. Non-overlapping company_id ranges (3597-3646 / 3647-3696).

All 60 resolved, 0 fully unresolved. 39 new companies minted across both shards (20 in p2t, 19 in p2u), several matched to pre-existing roster companies instead (Reken→RWW, Ritterhude→Osterholzer Stadtwerke, Neubiberg→split SWM/Ottobrunn, Borchen→Wasserwerke Paderborn, Bedburg-Hau→Stadtwerke Kleve, Schermbeck→split RWW/Wittenhorst, Gräfelfing→Würmtal-ZV, Wentorf+Barsbüttel→Hamburger Wasserwerke, Kirchheim b.München→gKU VE München-Ost, Brieselang→WAH Havelland, Roßdorf→ZVG Dieburg (Gundernhausen part), Cremlingen→Wasserverband Weddel-Lehre). 4 pending_domain (Wasserversorgungs- verband "Neckargruppe" for Edingen-Neckarhausen, Gemeindewerke Brühl GmbH & Co. KG, ZV Endlhauser Gruppe, ZV Wasserversorgung Kraichbachgruppe — all confirmed real suppliers via Impressum/registry with no independently verifiable own site).

Both shards ran their own domain-collision self-check before finishing and each caught and fixed its own duplicate mints on the first pass this time — p2t self-caught 6 (ZVG Dieburg, Zweckverband Freising-Süd, rhenag AG, Kreiswerke Main-Kinzig, Kreiswerke Grevenbroich, Wasserbeschaffungsverband Harburg, all already on disk from earlier p2q/p2k/p2e/p2c shards), p2u self-caught 3 (KEW AG, Mainzer Netze, WAZ Niedergrafschaft) — both deleted their own duplicate roster rows and repointed link rows before reporting done, rather than leaving it for the orchestrator. p2u also flagged a pre-existing duplicate not its own (Zweckverband Gruppenwasserwerk Dieburg allegedly still double- minted) and p2t flagged a possible post-merge kew.de collision against p2u's range — both flags were verified false positives on inspection of the actual shard files: neither ZVG Dieburg nor KEW appears in the final p2t/p2u roster shards at all (both were removed by the shards' own self-fixes before the files were written), so the subagents' own end-of-turn prose was describing a state that no longer matched their own on-disk output by the time they reported it. Lesson reinforced: verify a subagent's collision claims against the actual files, not its summary — this run's false-positive flags went the "safe" direction (over-caution) rather than a missed real collision, but either way the written files are the ground truth, not the report.

Ran the mandatory orchestrator-level post-merge domain-collision check anyway, exactly as the skill requires regardless of what shards report: across all roster.part-*.jsonl shards (50 files) before consolidate_roster.mjs, then again on the final merged roster.jsonl — both passes found only the same 2 pre-existing known/accepted collisions (sw-augsburg.de, emkendorf.de) and zero new ones, confirming the two shards' self-fixes actually held and neither flagged-but-unverified concern was real.

Ran the Finish sequence: map_roster.mjs (7,162 links total, 32 unmatched — up from 6 last run, mostly new Ortsteil/administrative-unit carve-outs from this batch's Saarland and Hessen member lists with no direct AGS by construction, plus 1 genuine ambiguous — "Steinbach" shared by 3 Gemeinden in Hessen/Rheinland-Pfalz/Thüringen, correctly left unmatched rather than guessed) → consolidate_roster.mjs (1,112 distinct companies, up from 1,073; 6 shard-level duplicates resolved by last-shard-wins, verified all 6 pre-existing from batches before this one — none in the 3597+ range this run used) → coverage.mjs → build_gv_layer.mjs. Population coverage 70.65% → 71.99% (+1.34pp); municipalities claimed 6,422 → 6,517 (+95, more than the 60 seeded — bonus harvest from member lists this batch, e.g. gKU VE München-Ost, Würmtal-ZV, Hamburger Wasserwerke picking up extra members beyond their seeded target).

Phase-2a pool remaining: 128 units / 1.44M people (next up: Wadersloh 12,848, Weeze 12,766, Altenstadt 12,764, Fuldatal 12,752, Winsen (Aller) 12,711, Neunkirchen 12,705, Dossenheim 12,690, Scheeßel 12,690, Mettlach 12,621, Buseck 12,527). Pool has dropped from 195 units this morning to 128 — roughly 2 more batches of this size should exhaust phase-2a entirely.

For next run: continue phase-2a from Wadersloh down, same method. Next free company_id starts at wv-de-3667 (this run's two shards used up to 3622 in p2t and up to 3666 in p2u, with some gaps freed by self-fixed dedupes — nothing above 3666 is taken). Keep the explicit "you may not use the Agent/Task tool" line verbatim in every subagent prompt — 9th consecutive clean batch, no recursion. Keep instructing shards to grep the existing roster on both municipality name and candidate company/domain before minting, and keep running the mandatory post-merge, cross-shard domain-collision check yourself regardless of what shards report — this run showed shards can now self-correct their own duplicate mints, which is good, but also that their end-of-turn prose can lag behind their own on-disk fixes or flag phantom collisions, so the orchestrator's own file-level check (not the subagent's summary) remains the only trustworthy signal. resolve_singleton.mjs remains unfixed (TASKDIR/_tasks ENOENT) — still not blocking, now unfixed across 5+ runs; worth a real fix soon given phase-2a is close to done and phase-2b (small singletons) will need it more.
