MaterializedPostgreSQL self-bootstraps its publication with CREATE PUBLICATION executed as the replication user, and Postgres requires CREATE on the database for that. With CONNECT alone the replication handler retry-loops on "permission denied for database ops" — the CH database appears but carries no slot, no publication and no tables. Found live on the hq-demo kind stand 2026-07-06; the fan-out variant (fanout/03_cdc_setup.sql) always carried the equivalent grant. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…-branch fan-out) Both sections now carry live output from the hq-demo kind stand (2026-07-06). §14: snapshot through the WAL pipeline (50/200/20/80), slot ops active with advancing flush LSN, publication with 4 tables, promotion collapsing to the same pg_ops__* hub counts as the §10 pull pass, live INSERT/UPDATE/DELETE round-trip, count()-vs-column-read tombstone semantics note, and the two-pass story (contention first, then the deterministic GRANT CREATE root cause fixed in cdc_setup.sql). §15: two per-branch Postgres DBs, two auto-named publications and slots, 10/30 + 8/20 snapshots, 12-second edit propagation with column-level detail, and a 0/0 cross-branch isolation check.

…ion race Commit 1784d5e (B2-mp4 re-record, prepared in a parallel working session) was cut from a pre-2ed9ea3 copy of demo_evidence.md and unintentionally reverted §14/§15 to the earlier attempted-blocked account, and stamped the header with "§14/15 did not complete". Re-apply the full live capture from 2ed9ea3 verbatim and reword the header note to match reality (blocked first pass, then GRANT CREATE root cause found and the sections captured live). No other B2 content from 1784d5e is touched. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The live 2-pod deployment could not complete — a fresh app image build stalled twice under severe, sustained shared-host contention (co-tenant container at up to 80% CPU, this session's own kind control-plane crash-looping). Documented honestly indocs/clickhouse-cutover-plan.mdPhase 3 and ADR 0010 rather than faked.All of this ran live against a real Mac kind stand via SSH (host shared with another project's containers, which were left untouched). Every section states its own capture method; nothing here is fabricated or backfilled.
