An account merge blanket-reassigned all of the secondary's identities to the primary,
so merging two accounts that each had a confirmed email (or telegram/vk) left the
survivor with two identities of one kind — which the profile and the retention dossier
both treat as singular (the profile showed an arbitrary one; a later change-email
journaled only one). The merge now keeps the primary's identity and journals the
secondary's colliding one to retained_identities (reason=merge) before dropping it, so
the survivor has one identity per kind and the absorbed credential still lands in the
legal dossier.
- migration 00008: widen retained_identities.reason CHECK to admit 'merge'
(expand-contract — Up only widens the set, so an image rollback stays DB-safe).
- accountmerge: dedupeIdentities + retainMergedIdentity before the identity reassign.
- inttest TestAccountMergeDedupesEmail; docs ARCHITECTURE §4 + retention.go reason note.
The statistics screen gains real depth, plus a hint-count bug fix found along the way.
- Best move per variant: the screen shows the actual best-move word (drawn as game
tiles; a wildcard shows its letter but no value), broken down by game variant, empty
variants omitted. New account_best_move table, written at game finish.
- Moves & hint share: two new lifetime tiles — the player's play count and the share of
plays that used a hint — from summed account_stats counters (moves, hints_used).
Honest-AI games are excluded, like the rest of the stats.
- Hint-count fix: the in-game hint badge no longer goes stale across games. The global
wallet now rides the wire apart from the per-game allowance (wallet_balance on
StateView/HintResult/StatsView), so the client reads the live wallet rather than a
per-game snapshot; game_players.hints_used now counts every hint (allowance + wallet),
its true per-game total.
- Account merge: sums the new moves/hints_used counters and merges the per-variant best
moves (higher score kept), which it previously dropped.
- Admin: the user card shows Moves and Hints used.
- UI polish: tab/label wording, game-over text, and e2e selectors hardened against label
changes.
All wire additions are trailing (backward-compatible). Docs (ARCHITECTURE, FUNCTIONAL +ru,
UISN_DESIGN) updated in step.
