Run complete. Enriched 30 water suppliers (all pending_domain-tier, population-priority order), resolved 7 official domains with zero collisions, and added 37 new municipality links, pushing population coverage 84.32%→84.39% (+122k people, 7,943→7,956 municipalities claimed). Caught and fixed a data-integrity bug mid-run (one subagent's domain patch was a partial record that would have silently wiped other roster fields on merge) and corrected a run_in_background slip by synchronously blocking on both subagents so no work was lost in this headless run. 78 pending_domain companies remain for the next batch; four open duplicate-mint pairs and one newly-discovered undiscovered entity (wv-ust.de) are flagged in the journal for a human pass.

Orchestrator run: read CLAUDE.md + this journal first, then SKILL.md. Roster was 1740 companies / 115 enriched (94 pending_domain per the 00:30 run's count, but that count was against a smaller roster before phase-2b VG3/VG4 discovery landed — recomputed fresh at 108 pending_domain against the current 1740-row roster). Built the batch with a new throwaway script (build_enrich_batch.mjs, left on disk, mirrors build_batch_input.mjs's pattern but for enrichment instead of discovery): all 30 rows were pending_domain, sorted by population served (computed from roster-links.jsonl, 18.6k down to 1.7k) — same priority order as the last 3 runs. Split into two 15-row shard files, spawned exactly 2 foreground subagents per the 6GB-cap rule.

Process note — corrected a mistake mid-run, not a repeat of the known anti-pattern: initially launched both subagents with run_in_background: true (a copy-paste slip), which conflicts with this run's headless-and-single-turn framing. Caught before losing anything: used TaskOutput(block: true) to synchronously wait out each agent's full run inside this same turn (shard A: 18min/1.08M tokens/158 tool calls; shard B: 28min/1.66M tokens/241 tool calls) rather than ending the turn "waiting." Net effect was the same as spawning them foreground, just an extra round-trip — flagging so a future run doesn't need to rediscover that TaskOutput(block:true) is the correct rescue if this slip happens again.

Data-integrity catch before merging, worth a permanent process note: shard B's domain-patch shard (roster.part-zzz9-enrich-j.jsonl) contained only 4 fields per row (company_id, official_domain, domain_status, notes), not a full roster record. Every prior enrich run's patch shards (-a through -h, checked directly) carry the full roster row (name, land, hq_ags, legal_form_verbatim, supplier_kind, etc.) with the domain fields updated — consolidate_roster.mjs does a last-shard-wins full overwrite keyed on company_id, not a field-level merge. Applying the partial shard as-is would have silently deleted name/land/etc. for the 7 companies it resolved. Fixed by spreading each patch onto its existing roster.jsonl row ({...base, ...patch}) before consolidating — verified all 7 resolved rows kept their full field set afterward. A future run's orchestrator should grep a subagent's roster.part-zzz9-enrich-* output for a land or name key before merging it — a patch shard missing those is the tell.

Domains resolved: 7/30 (shard A: 0/15, shard B: 7/15 — consistent with shard A's batch being disproportionately small ZVs administered off VG/Amt sites with genuinely no own domain, vs. shard B catching several standalone Gemeinden and one large ZV rebrand): wv-de-2908 Gemeinde Seedorf → gemeinde-seedorf.de, wv-de-2652 Zweckverband Hesselberg-Gruppe → hesselberg-gruppe.de, wv-de-369 Zweckverband Wasserwerk Wacken → wasserwerk-wacken.de, wv-de-5525 Stadt Wiesensteig → wiesensteig.de, wv-de-5535 Zweckverband Gnotzheimer Gruppe → gnotzheimergruppe.de, wv-de-6017 Gemeinde Untersteinach → untersteinach.de, wv-de-5521 Gemeinde Rott → rott-lech.de. All 7 grep-verified against roster.jsonl post-merge: zero collisions (same 5 known pre-existing collisions as every prior run — sw-augsburg.de, wvv.de, zvo.com, vgrd.de, emkendorf.de). 23/30 stayed pending_domain, mostly the by-now-standard "shared VG/Amt/Gemeinde host whose Impressum doesn't name this specific member" pattern — several explicitly avoided attaching a shared domain (wv-de-4710 Spardorf reconfirmed the existing vg-uttenreuth.de collision-risk flag from a prior run; wv-de-4337 Mespelbrunn similarly left off vgem-mespelbrunn.de).

Notable substantive finds surfaced during research (see shard B's own detailed journal entry immediately above this one for full sourcing): wv-de-2652 Hesselberg-Gruppe merged 2026-01-01 with the still-pending wv-de-2653 Rastberg-Gruppe and absorbed Wassertrüdingen's own municipal supply — Rastberg-Gruppe is likely now defunct, flagged for human reconciliation rather than auto-merged. wv-de-369 Wasserwerk Wacken is actually a 3-member bulk body (Kreis Steinburg + Stadt Brunsbüttel + a wholly undiscovered "Wasserverband Unteres Störgebiet", own site wv-ust.de) — the new entity is a discovery-sweep candidate, out of this skill's scope, not added to the roster here. wv-de-4337 Mespelbrunn's water supply is explicitly joint with Heimbuchenthal (wv-de-4333), contradicting the roster's existing self_only tag — flagged, not corrected (out of this skill's write scope). wv-de-823 Wasserleitungsgenossenschaft Stapel had a handelsregister_nr upgraded from null to a found Genossenschaftsregister number (GnR 15 SL).

New host traps: rangendingen.eu (TLS handshake ALERT internal error), vg-partenstein.de (403 to curl+WebFetch), partenstein.de (connection timeout, unreachable), branchenbuch.meinestadt.de (403, previously fetchable), gnotzheimergruppe.de (403s curl on every URL but tolerates WebFetch on the bare homepage only — inconsistent block, not a hard block), rott-lech.de's water subpages (search-indexed but 404 live, likely a recent site restructure).

Tooling gap reconfirmed: pdftotext/poppler is still not installed in this sandbox (hit on Gomadingen, Wacken, Untersteinach and Rott PDFs this run) — this has now recurred across enough runs (see 2026-08-22, 2026-08-27 20:30, and this one) that it's worth a deliberate provisioning decision rather than a per-run workaround.

Mechanics: enrichment.part-i.jsonl (15) + enrichment.part-j.jsonl (15) merged into enrichment.jsonl (115 → 145 records; jq-validated, zero duplicate company_ids, zero overlap with the pre-existing 115). roster.part-zzz9-enrich-j.jsonl patched to full records (see above) before consolidate_roster.mjs. New links roster-links.part-zzz9-enrich-i.jsonl (15) + -j.jsonl (22). map_roster.mjs: 9121 total link rows (was 8867 three runs ago at the last full recount; 139 unmatched / 3 ambiguous, an expected accretion from genuinely new raw names, not a regression) → consolidate_roster.mjs: 1778 shard rows → 1740 distinct company_id, unchanged (enrichment mints no new companies, as expected) → coverage.mjs.

Population coverage: 84.32% → 84.39% (+0.07pp, +122k people). Municipalities claimed 7,943 → 7,956 (+13) — new links came from Ilsfeld/Crailsheim/Jagstzell/Kressberg/Rosenberg/Marbach/ Hohenwart cluster (shard A) plus the Hesselberg-Gruppe merger cluster and Kreis Steinburg/Brunsbüttel (shard B). Residual: 2,987 municipalities, 13.05M people (12.6%). export_csv.mjs was also run per SKILL.md's literal Finish text, but it only renders the 25-row 2026-08-12 pilot (companies.jsonl/links.jsonl) — confirmed (again) this is disconnected from the real enrichment.jsonl/roster.jsonl pipeline the last 3 enrich runs actually use; harmless no-op, not worth re-flagging every run unless someone builds the real exporter.

For next run: 78 pending_domain rows remain in the unenriched pool (108 at batch-build time minus this run's 30, all of which left the "pending" set regardless of resolution — enrichment status, not domain status, drives pending). 1620 roster rows remain pending enrichment overall (1740 - 120 enriched-and-in-current-roster; enrichment.jsonl's total of 145 also carries 25 pilot IDs not on the current roster at all, per the 2026-08-27 15:57 entry). Open duplicate-mint/merge items needing a human pass, now numbering four: wv-de-1113/817, wv-de-1174/2209, wv-de-981/3397 (all carried from before), plus this run's wv-de-2652/2653 (Hesselberg/Rastberg, better-evidenced than the others — an explicit "merged 1.1.2026" statement on the surviving entity's own site). Also open: two domain-collision borderline calls from 2026-08-28 00:30 (Weimar wv-de-4738/419, DESWA wv-de-3070), and a new undiscovered entity for the next discovery sweep to pick up (wv-de-369's Wasserverband Unteres Störgebiet, wv-ust.de).
