An audit against the standard the series set — concepts, procedure, commands, architecture diagram, evidence table, terminal output — found the three new experiments met it while twelve of the original ones had no diagram at all: A-0, A-1, A-3, A-4, A-5, A-6, A-8, B-0, B-2, B-7, C-2, D-2. Each now has one drawn from what that experiment actually found, not filler: A-0 shows sharing going through PostgreSQL rather than between the caches; A-3 the gap between the 200 and the WAL flush, with both failed injections; A-5 the three silent injection failures; A-6 the two places latency is multiplied; B-0 the repository keyed by principal with no session id; B-2 the primary key that causes the overwrite; D-2 why the rolling update stopped the accident halfway. Also corrected the index's stale claim of 11 experiments without a screenshot — it is 14, and the reason is recorded: those experiments were measured from terminals, the database and logs, and the observability stack does not scrape Redis, the BFF or PostgreSQL, so there is no console to photograph.
