Enrichment run complete: 45 water-supplier companies researched (23+22 split across two synchronous subagents), all appended cleanly with no overlaps. enrichment.jsonl grew 975→1020 lines (970→1015 distinct companies), roster-links.jsonl gained 157 new municipality links, and population coverage held at 99.87% (10671/272 claimed/residual). Two roster data-quality issues were flagged for human review (a likely digit error in BRW's member count, and self-contradictory member notes for two other operators), plus new PDF-tooling gaps (no pdftotext/python3, WebFetch PDF hallucination risk) and CMS host quirks were logged in the journal for the next run.

Read CLAUDE.md and journal tail, then SKILL.md in full. State on entry: 3212 roster companies, 970 distinct enriched (975 lines), 99.86% population coverage (10670/272 claimed/residual, per the 13:00 discovery run just before this one).

Batch build: build_enrich_batch_excl.mjs 45 enrich-20260901-1530 (still needed — the standing 6-id duplicate-mint exclusion set is separate from the roster). 2 pending_domain rows

• 43 by population served. Split 23/22, dispatched as two synchronous general-purpose Agent subagents in one message, both run_in_background: false, both carrying the mandatory no-Agent/no-Task-tool instruction and told to append incrementally to shard-specific part files only (never touch enrichment.jsonl/roster-links.jsonl directly). Both completed inline (~1071s / ~1692s), neither recursed into sub-subagents.

Shard A (23, incl. both pending_domain): 23/23 complete. Both pending_domain rows stayed pending_domain — genuinely no independent website for either (wv-de-19863 Zweckverband Hohe Rhön: WebSearch suggests dissolved 2014-12-31 into WAZV Bad Salzungen, not primary-source verified in this environment — flagged, not acted on; wv-de-19910 Wassergemeinschaften Peissen: confirmed informal household cooperatives via Amt Itzehoe-Land's own page). Field recovery: phone 22/23, email 17/23, website_url 21/23, emergency_phone 16/23 found (7 honestly not_found after following labelled links), contact_form_url 9/23, analysis_url 12/23, multi_zone 8/23. 75 new municipality-link rows across ~19 companies (biggest: BRW 35). Roster discrepancy flagged (not applied): wv-de-5515 (BRW) roster says 135 member municipalities, operator's own members page lists exactly 35 — likely a digit-read error upstream, worth a human check. Also wv-de-225's Impressum path (/impressum/ 404s, real path /rathaus/impressum/) — another instance of the known unguessable-path trap.

Shard B (22, all known-domain): 22/22 complete. Field recovery: name/address/phone/ website_url/supply_area 22/22, email 20/22, handelsregister_nr 11 found + 11 not_applicable, emergency_phone 21/22, analysis_url 19/22 (3 genuine dead ends: Heppenheim, Bernkastel-Kues, GWAZ Guben). 82 new link rows. Two roster note self-contradictions flagged, not corrected: wv-de-365 (Bernkastel-Kues) roster text claims "21 Ortsgemeinden" while enumerating 22 names and also mis-describing Kommen as excluded when it's in the list; wv-de-1132 (GWAZ Guben) roster's member list conflates Verbandsversammlung governance seats (incl. two Ämter) with actual drinking-water customers — recorded with an explicit caveat rather than treating all 9 as confirmed supply relationships.

New tooling gap for future runs: this environment has no pdftotext/python3, and WebFetch's summarizer returns garbled/binary content for PDFs and can hallucinate entity names from partial markdown (shard B: asked to name Northeim's Ortschaften, WebFetch invented 38 names including towns 50km away in Hessen — discarded, not recorded). This capped evidence_value/confidence on several otherwise-correctly-located analysis PDFs. New host patterns worth folding into SKILL.md's Memory Safety section: JS-rendered download-list web components on RLP's "ionas4"-family municipal CMS (bernkastel-kues.de, wasser-schweich.de) that hide PDF links from static fetches; a real PDF served under literal .pdfx extension (stadtwerke-leichlingen.de); Latin-1 %E4 umlaut encoding on kelkheim.de's CMS (UTF-8 %C3%A4 404s).

Merge: both shard files validated well-formed JSONL (23/23, 22/22), all 45 batch company_ids present exactly once across both shards, 0 overlap with pre-existing enrichment.jsonl. Appended directly: enrichment.jsonl 975 → 1020 lines, 970 → 1015 distinct company_id (+45 exact). Appended the two roster-links.part-shard{A,B}-2026-09-01-1530 files and ran map_roster.mjs (the live additive-merge path, not map_ags.mjs — still holds per the 05:30/10:30 runs' finding). roster-links.jsonl 15499 → 15656 rows (+157 = 75+82, exact). coverage.mjs (safe, non-destructive): claimed 10670 → 10671 (+1), population 99.87% (unchanged at this rounding), residual 272 municipalities / 104.7k people (was 273/106.5k before the 13:00 discovery run's own contribution — small net movement this pass, mostly link enrichment rather than new claims).

For next run: continue by population served — build_enrich_batch_excl.mjs 45 will pick up where this run left off. Roster-wide pending_domain count is now 316 (not the small handful implied by past "cleared the queue" entries) — discovery sweeps keep minting more delegated-supplier rows faster than enrichment resolves them (matches SKILL.md's own note that this is expected). Two new roster-data discrepancies await a human decision: wv-de-5515's member-count (135 vs. actual 35) and wv-de-365/wv-de-1132's self-contradictory member notes. No pdftotext/python3 in this environment (confirmed again, now also documenting the WebFetch PDF-hallucination risk it causes) — worth an actual fix to SKILL.md's Memory Safety section covering both the JS-rendered-download-list and .pdfx-extension traps found this run. SKILL.md's Finish section still names the stale map_ags.mjs/export_csv.mjs pair instead of the live map_roster.mjs + coverage.mjs path — flagged across many consecutive enrich runs now, still unfixed. Standing backlog unchanged: 6 duplicate-mint pairs, ~28-30 domain-collision review queue, GIPS-platform email cipher (Balingen/Gaggenau/Hemer/Wedel, still uncracked).
