Everything is clean — no leftover temp directories, all files updated and consistent. The run is complete.

Batch of 45 German water suppliers enriched (contact details + published water-analysis links), merged cleanly into enrichment.jsonl (2109→2154 distinct companies) and roster-links.jsonl via the live map_roster.mjs→consolidate_roster.mjs→coverage.mjs pipeline; population coverage holds at 99.99% (this batch enriches already-claimed rows, doesn't discover new ones). Field recovery: 45/45 address/phone/website, 37/45 email, 41/45 (91%) got a real published analysis link — above the campaign's historical rate. One operational hiccup worth flagging: both research sub-agents I dispatched spontaneously spawned their own background sub-agents instead of researching directly, which I caught and recovered from by monitoring their 8 grandchild agents to completion rather than losing the work — logged as a process note in the journal for future runs. Six new roster discrepancies (e.g. Weida-Land's site being fully unreachable, a two-entity split at Lambrecht, an HR-registration exception at Altensteig) were flagged for human review, not auto-corrected.

build_enrich_batch_excl.mjs 45 → 0 pending_domain (roster 3375, 2109 enriched entering, 1286 pending, 6 standing duplicate-mint pairs excluded). Split shard A (23) / shard B (22), dispatched as two top-level Agent calls in the same message.

Process note for future runs, worth reading before delegating this skill's batches again: both top-level agents, unprompted, split their own assignment further into 4 smaller sub-agents each (launched in their background) and then ended their own turn immediately, reporting back to me as "done — waiting for my children" before any research had actually happened. Checked immediately after both calls returned: shard A had 2/23 companies written, shard B had 0/22 and no output file yet — this is exactly the failure mode the skill's Resumability section warns about, just one recursion level down from where the warning is written. The 8 grandchild agents were still visible and running via ListAgents (their agentIds appear as ordinary subagents, not hidden inside the parent), so nothing was actually lost: started a Monitor polling distinct company_id count across the known shard/tmp files, then blocked on it with repeated TaskOutput(block=true) calls until all 8 finished naturally (9-21 minutes each, 45/45 reached). Takeaway: when directing a subagent to do this skill's research, its prompt should say explicitly not to further delegate/spawn its own background agents — "do the research yourself, do not spawn subagents" — since the instruction against backgrounding in SKILL.md evidently doesn't automatically propagate to an agent's own delegation choices one level down.

Verification before merge: shard A wrote directly to enrichment.part-shardA-enrich-20260906-0030.jsonl (23 lines, all 4 of its own sub-agents appending to the same shared file with no corruption — checked every line parses); shard B's 4 sub-agents each wrote to their own .tmp-shardB-20260906/enrichment-group{1..4}.jsonl (6+6+5+5), moved to individually-named enrichment.part-shardB-enrich-20260906-0030-g{1..4}.jsonl before merge. Combined: 45/45 distinct company_id, exact match against the two batch files, 0 missing, 0 extra, 0 bad JSON lines, 0 collisions with the existing 2109 records. enrichment.jsonl 2114 → 2159 lines (2109 → 2154 distinct company_ids, +45). map_roster.mjs: 21171 → 21368 links (+197, matching the shards' 130+16+17+27+7 exactly). consolidate_roster.mjs: still 177 shards / 3375 distinct companies (unchanged, expected); roster-links.csv 18054 distinct after dedup. coverage.mjs: population 99.99% → 99.99% (unchanged, expected — this batch enriches already-claimed rows, it doesn't discover new ones), same 24 residual municipalities / 11,023 people, Hartmannsdorf-Reichenau still largest at 1,040.

Non-suppliers found: 0 — all 45 confirmed genuine, currently active drinking-water suppliers.

Field recovery (45 companies): name/address/phone/website_url 45/45; email 37/45 found; emergency_phone_number 37/45 found (rest genuinely checked Notdienst/Störung pages and came back empty, not skipped); contact_form_url 20/45 (most of this batch's small Eigenbetriebe only publish phone/email, no web form); legal_form_verbatim 37/45; handelsregister_nr genuine found for only 4/45 (rest correctly not_applicable, mostly scraped from an explicit KdöR/AöR Impressum phrase rather than inferred from the name). Analysis locator: 41/45 (91%) got a real analysis_url, well above the campaign's historical ~70% real-supplier rate — this batch skewed toward larger self-supplying Gemeinden with well-maintained sites; 36/41 tier 1 (real lab values), 22/45 (49%) multi_zone, 5 used a third_party_fallback (upstream bulk supplier's own page, e.g. wv-de-18714 Pilsting → Stadtwerke Landau a.d.Isar). The 4 misses were an SPA that neither curl nor WebFetch could render (wv-de-1103's sw-lambrecht.de is unaffected — Lautertal was the miss), a generic tier-3 compliance statement with no numbers (Eiterfeld), and two genuinely no-analysis cases documented after real navigation, not roster defects.

Roster corrections/questions flagged for human review, not acted on:

• wv-de-19272 Wackersberg: a Bebauungsplan doc suggests the Arzbach area may actually be served by a separate Wasserbeschaffungsverband, not Wackersberg itself — contradicts self_only.
• wv-de-1509 Trinkwasser- und Abwasserbetrieb Weida-Land AöR: weida-land.de was completely unreachable all session (connection refused on both http/https, www/apex, verified via WebFetch and curl) — new host-down trap, not a content-absence finding; all fields recorded low-confidence from search snippets only, need a re-check pass. Separately, a Sachsen-Anhalt ministry PDF suggests TAWL actually serves the whole Verbandsgemeinde (Schraplau + Alberstedt/Esperstedt/ Kuckenburg), not just self_only as the roster has it.
• wv-de-18726 Tuntenhausen: roster says partial (1 member), but the Gemeinde's own page states it also supplies parts of Emmering, VG Assling (Kronau, Angelsbruck, Ried) and Bad Aibling (Wilpasing), while parts of Tuntenhausen itself go to separate Wasserbeschaffungsverbände — structurally a list_found case, not partial. 5 extra tentative link rows recorded at medium confidence pending review.
• wv-de-1103 Verbandsgemeindewerke Lambrecht: two distinct legal entities exist behind one seed row — the actual legal operator (Eigenbetrieb, vg-lambrecht.de, 5 members: Elmstein, Esthal, Frankeneck, Neidenfels, Weidenthal) vs. Stadtwerke Lambrecht (Pfalz) GmbH (HRB 42037, private, sw-lambrecht.de), which holds the technical-operation contract and hosts every water-quality PDF including the Eigenbetrieb's own members' data. Kept official_domain as vg-lambrecht.de per the dedup rule but flagged sw-lambrecht.de as the practical document/contact domain — needs a human call on whether this should split into two roster rows.
• wv-de-4419 Stadtwerke Altensteig: genuinely Handelsregister-registered (HRA 341084, Amtsgericht Stuttgart) — breaks this shard's otherwise-uniform KdöR not_applicable pattern; also partially cross-supplies neighbouring Gemeinde Ebhausen (AGS not looked up, out of scope).
• wv-de-18741 Gemeindewerke Rednitzhembach GmbH: the GmbH has no separate site/Impressum of its own (only the Gemeinde's exists); third-party registers (Northdata/Creditreform) claim HRB 15318 Amtsgericht Nürnberg, but per the campaign's own-site-only evidence rule this was recorded not_found rather than trusted from a non-operator source — flagging in case a human wants to verify and backfill it from an authoritative source.
• wv-de-10508/wv-de-10507 Daxberggruppe / Markt Pöttmes: apparent overlap (both roster rows share hq_ags 09771156) reconciled, not a conflict — Daxberggruppe's own site names Pöttmes as a member for exactly 5 named Ortsteile plus Gemeinde Hollenbach (1 member Ortsteil + 3 Wassergäste), consistent with Pöttmes separately running its own Eigenbetrieb for the rest of its territory.
• wv-de-8012 Verwaltungsgemeinschaft Syrgenstein: resolved as one joint water system across all 3 members (shared employee, 1 Pumpwerk, 3 Hochbehälter, single bulk source Stadtwerke Giengen), not 3 separate Eigenbetriebe, despite being a VG rather than a Zweckverband.

New host traps this batch: weida-land.de fully unreachable, not just slow/blocked (see above); wasser.bnnetze.de (Schallstadt's bulk-supplier analysis host) fails TLS handshake with "SNI unrecognized name" on both curl and WebFetch — Schallstadt's own page names this exact URL, so documented as unreachable, not not_published; wasserportal.info is a BDEW-run Angular SPA that neither curl nor WebFetch can render (hit for both wv-de-18738 Lautertal and referenced by wv-de-18740 Eiterfeld) — a third-party fallback host worth recognizing on sight in future batches; hardegsen.de needs the same Niedersachsen NOLIS ?vs=1 bypass param already logged for Bad Grund/Nörten-Hardenberg; vg-lambrecht.de returns HTTP 403 to generic curl ("Request forbidden by administrative rules") but 200s to WebFetch's browser-style fetch; email-obfuscation schemes keep diversifying — this batch alone saw a Caesar-shift mailto (Bischofswiesen, decoded), HTML-entity encoding (Calden, decoded) and an unresolvable JS/CSS scheme (Jettingen-Scheppach, correctly left not_found). Recurring, not new: this environment still has no pdftotext/python3/strings, so CID/Identity-H-encoded and DCTDecode/CCITTFax-scanned PDFs keep scoring evidence_value: null even when the document genuinely exists — every sub-agent this batch correctly treated that as a tooling limit, not a not_published verdict.

For next run: continue with build_enrich_batch_excl.mjs 45. Still 0 pending_domain, 1241 other pending (3375 roster total, 2154 distinct company_ids enriched, 6 excluded). New standing items from this pass: Wackersberg/Arzbach operator question, Weida-Land host-down + Verbandsgemeinde scope question, Tuntenhausen list_found reclassification, Lambrecht two-entity split question, Altensteig HR/Ebhausen cross-supply note, Rednitzhembach HRB third-party-only question. Also worth a maintainer's attention independent of any one company: read this entry's process note before dispatching this skill's two shard agents — say explicitly in their prompts not to spawn their own background sub-agents, or verify actual file output within a couple of minutes rather than trusting a "done" report. All prior standing items carried in the 2026-09-05 20:30 and earlier entries (Strohgäu domain-correction, Feldkirchen (Lkr. München) operator question, Horstmar concession/operator question, Aldenhoven Niederzier second-zone gap, Küps/Kronach boundary question, Langenargen/ZWUS interconnection question, ZWV Westpfalz contact-domain question, two dead roster URLs, Schwarzenbruck GmbH wrong-entity question, Lechraingruppe/Hardhofgruppe 4th-member question, Bad Endbach HR exception, Fuchstal/Vilgertshofen source question, Neunkirchen a. Brand/Rosenbach operator question, and the long tail of older items) remain open, none touched this pass.
