Diagnosis

The E2E battery encodes a stale documented policy (<12 chars → 422 WEAK_PASSWORD) that no longer matches the live API, which implements 8 chars + uppercase required and returns field-level validation failures:

Password	Live API
`Short1!` (7 chars)	400 `VALIDATION_ERROR` – `Password must be at least 8 characters`
`strongpass123!` (14 chars, no uppercase)	400 `VALIDATION_ERROR` – `Password must contain at least one uppercase letter`
`Strongpass123!`	201

Failure body: {"success":false,"data":[{"field":"Password","message":...}],"error":{"code":"VALIDATION_ERROR"}}

Key proof: strongpass123! is 14 chars — it would pass the documented 12-char rule, yet the live API rejects it. The implementation moved to 8+uppercase, and internal/validation/custom_validators.go's comment still says "12 chars" (unchanged docs, changed code), so the battery kept asserting a spec that no longer exists. The API is the source of truth (probes confirm the contract), so the battery is what gets fixed.

Fix (in the doc)

Battery cases: swap 422/WEAK_PASSWORD → 400/VALIDATION_ERROR for both weak-password cases and assert the exact data[0] field/message strings from the probes.
Passwords: use Strongpass123! (14 chars: upper/lower/digit/special) as the canonical success-path password everywhere the battery registers — including shared helpers that silently 400'd with legacy all-lowercase passwords.
Response parser: parse the new full envelope (success, data[].field/message, error.code) instead of a flat code.
Anti-drift: fix the stale "12 characters" comment in internal/validation/custom_validators.go.

Verification (in the doc)

The repo is private/unreachable from this environment (no GitHub auth, no local copy), so I reproduced the validator + battery assertions in Go (/tmp/heliosim) — the old battery fails exactly the two weak-password cases against live behavior; the fixed battery passes all three (400/400/201 with exact messages), matching the tick-266 probes.
The doc also includes live curl checks and in-repo go build/battery-run/grep commands to run after applying the edits.
