 Live callers of the canonical path: `/tg score set` (`subcommands/score/set.ts`), the score modal (`handlers/modals.ts`), and `/tg-admin score-inject`.
 
+**tg-history file shape — fixed 2026-07-31, was silently dropping every field but `scores`.** `Score.submit`'s local `loadHistory`/`saveHistory` used to round-trip only `{ scores: TGScore[] }`, never reading/writing `date`/`slot`/`confirmed`/`nationKD`. The FIRST score ever submitted for a new TG key would create a file with nothing but `scores` on it — permanently, since nothing else ever wrote the rest back in. This diverged from the older `systems/history.ts`'s `upsertScore()` (a parallel, largely-legacy code path — see `/tg result view|set|post` vs `/tg-admin result post` below), which always initializes the full `TGResult` shape and is what the current admin result path was silently assuming existed. Found 50 affected files in dev's `data/tg-history/` alone (spanning weeks), almost certainly present in prod too. `loadHistory` now fills in any missing fields from `TGKey.parse(historyKey)` + sane defaults every time it reads a file, self-healing on the next score submitted for that key. `scripts/migrate-history-shape.py <data_dir>` does a one-time backfill for files that won't get touched again (safe, idempotent, gitignored data dir) — **run this on prod too**, same as `migrate-stats-shape.py`/`fix-class-keys.py`.
+
+**Two parallel result-posting systems exist and don't fully agree on file shape** — `/tg result view|set|post` (`subcommands/result/{view,set,post}.ts` + `systems/history.ts`'s `loadResult`/`upsertScore`/`setNationKD`) directly reads `result.nationKD.capella.k` etc. and would throw on a scores-only file. `/tg-admin result post` (`subcommands/admin/result-post.ts` + `systems/result.ts`'s `Result.post` + `PersistentMessage`) is the newer canonical path — it never reads `nationKD` from the file at all, computing K/D by summing `score.k`/`score.d` directly, so it was unaffected by the missing-fields bug even before today's fix. Not consolidated; be aware which one you're touching.
+
+**`Result.post()` now returns `{ ok: boolean; reason?: string }`** instead of `void` — fixed 2026-07-31. It used to silently no-op (results channel unconfigured, or zero rows from `buildRows` — e.g. no attendance AND no scores for that historyKey) while `/tg-admin result post`'s handler unconditionally replied "✅ Result posted" regardless of whether anything happened. All four callers (`admin/result-post.ts`, `index.ts`'s `allScoresSubmitted` listener, `scheduler/midnight-results.ts`, `scripts/backfill-results.ts`) updated to check it; the admin command now surfaces the real reason to the officer instead of a false positive.
+
 **`src/systems/scores.ts`** is a parallel legacy module (`submitScore`, `normalizeSlot`, `detectSlot`) that does **not** emit `RuntimeEvents` — a write through it silently skips Leaderboard/Result updates. Its `submitScore` export is only imported by `src/subcommands/score/submitCore.ts`, which is itself unused dead code (no other file imports it) — safe to delete, but harmless as-is. `normalizeSlot`/`detectSlot` from the same file *are* still actively used by several live subcommands (`score/set.ts`, `score/get.ts`, `result/*.ts`) — only `submitScore` itself is the dead/bypassable part.
 
 ### Character class serialization
 `Character.class` is typed as `CharacterClass` (object) in memory but stored as plain `ClassKey` string on disk. Hydration/dehydration boundary lives in `characters.ts`: `Char.hydrate(raw, ownerKey)` expands on read, `Char.dehydrate(char)` collapses on write.
 
-**`src/helpers/serialize.ts`** — safe accessors for use at write boundaries *outside* `characters.ts`: `serializeClass(cls)`, `hydrateClass(cls)`, `serializeCharacter(char)`, `hydrateCharacter(raw)`. `serializeClass()` is now wired into `Score.submit` (`score.ts`) as of the current uncommitted change — replaces the unsafe `character.class.key` access that throws if `class` is already a plain string. This is the first of the write boundaries fixed; other call sites doing `typeof x.class === "object" ? x.class.key : x.class` inline (`format.ts`, `result.ts`, `poll.ts` conflict/vote-entry paths, etc.) haven't been swept to use the shared helper yet — functionally safe (same defensive check), just not consolidated.
+**`src/helpers/serialize.ts`** — safe accessors for use at write boundaries *outside* `characters.ts`: `serializeClass(cls)`, `hydrateClass(cls)`, `serializeCharacter(char)`, `hydrateCharacter(raw)`. `serializeClass()` is wired into `Score.submit` (`score.ts`) at the `TGScore.class` write. **2026-07-31: found a SECOND unsafe `character.class.key` access in the same function** (`Score.submit`'s call to `WRank.recordScore(...)`, a few lines below the already-fixed one) — proof the sweep is genuinely incomplete, not just theoretically so; `MERGE_CHECKLIST.md`'s "run `fix-class-keys.py` every merge" requirement is still real and should NOT be assumed retired. Other call sites doing `typeof x.class === "object" ? x.class.key : x.class` inline (`format.ts`, `result.ts`, `poll.ts` conflict/vote-entry paths, etc.) haven't been swept to use the shared helper yet — functionally safe (same defensive check), just not consolidated.
+
+**Downstream rendering must tolerate a missing/undefined class too** — `Emoji.class()` and `Emoji.nation()` (`src/systems/emojis.ts`) used to call `.toLowerCase()` directly on the extracted key with no guard, crashing the whole interaction (`Cannot read properties of undefined (reading 'toLowerCase')`) whenever a `TGScore.class` was missing AND the character it referred to no longer existed in `CharacterRegistry` (deleted/renamed character with orphaned old history). Fixed 2026-07-31 — both now return `""` for a falsy/missing class or nation instead of throwing, letting the `Emoji.class(x) || x || "?"` fallback pattern already used throughout the layout files degrade to a `"?"` placeholder instead of killing the command.
 
 ### Poll persistence
 `src/systems/pollPersistence.ts` — serializes `Map`/`Set` to JSON arrays, persists to `data/poll-state.json`. `persist.save(polls)` after every mutation; `persist.load()` on `clientReady`. `/tg poll reload poll` reloads from disk + re-renders.

Returns `{ value?, error? }`, not a bare number — callers check `.error`, not `=== undefined`, since a value can now fail for two different reasons (bad format vs. above the sanity cap) and each needs its own message.
+- **Sanity ceiling (`Config.tg.maxStatValue`, default 50,000,000, `/tg-config tg set-max-stat-value`)** — added 2026-07-31 after real corrupted data was found in prod (players typing e.g. `150.0M` or `124000M`, both intended as a single realistic value but parsed literally per the shorthand rules into a nonsense multi-billion number, silently accepted with no upstream check). Deliberately configurable rather than hardcoded — real observed ATK/DEF tops out around 10-13M today, but that ceiling is a game-balance fact that can shift, not a hard invariant of the code.
