- Shared card pool and item stock as in the official mode (the owner's request, from the 路标档案馆 video and public notes): solo low-tier exceptions, co-op operators x2, shared item stock with special-item exceptions, normal / advanced occupancy 1 / 2, re-check on buy, 机变 exhaustion, release on consume / destroy / elimination; 整备 never exceeds stock; invariant held <= cap. - 突袭: one taunt-first reselect right after a revive (the owner's rule); ordinary polls and redeploys keep the 0.2.3 rule; a revive on an enemy's tile stays. #475: online boss / hidden-boss Raid may land on the empty half (owner-limited scope). - 浊心斯卡蒂 S1 x 坚守 no longer bounce redirected damage, and the two shares conserve the hit (idea of PR #464 by @HappyTanuki). - Operator fixes adapted from PRs by @Xinglan233 (#459 哈洛德 S2 elemental trigger, #460 涤火杰西卡 shield on the four adjacent tiles, #461 家族徽章 first hit after stealth, #462 松果 S2 regrow per deploy); 克莱门莎 S2 splash 1.1 / 100% ATK and air auto-trigger (#467); 白面 copying 歌蕾蒂娅 / 余 skips the three-member condition (#473, the owner's video). - 香槟炸弹 is not chosen by friendly auras / heals (PR #468 / #476 by @Siornya); 琳琅诗怀雅 coin balance (PR #450 by @IceCodeNew); Touch prep display (PR #451 by @YinqiMargatroid); lobby header (PR #471 by @YuriRestia); Japanese UI terms (PR #448 by @scutkane). - AI-only boss countdown grace, render-failure cache / recovery without restarting a battle, device units kept on a same-field re-entry, DIY detail / skill previews, large-text result buttons. - golden: battle families equal 0.2.3 except diy-135 / diy-136 (克莱门莎); all 18 release matches move through the shared pool, every flip named in docs/history/0.2.4.md §29.12; two coverage scenarios added.

# Golden results
|
||
|
||
The simulation is deterministic: the same seed and inputs give the same battle and the same match, bit for bit. These
|
||
files record the exact outcome of a fixed corpus of seeded scenarios, so a change that alters gameplay — even one meant
|
||
to be a pure refactor that only reorders random draws, hook order or iteration order — fails loudly instead of slipping
|
||
through.
|
||
|
||
- `tools/golden.mjs` builds the corpus from `data/*.json` (fixed order, fixed seeds) and reduces every scenario to a
|
||
digest. Its header documents the families and the digest fields.
|
||
- `test/golden/<family>.json` hold the digests (`roster`, `bonds`, `fields`, `matches`, `standins`, `diy`).
|
||
- `test/golden.test.js` recomputes them and compares. On a mismatch it prints the scenario, the field and old → new.
|
||
|
||
## The corpus
|
||
|
||
| family | what runs |
|
||
|---|---|
|
||
| `roster` | 49 battles: every visible chess record (normal and elite) with every selectable skill and module (DESIGN §16), 12 operators per battle on a real stage (all 11 in turn) against the round's real wave three times over, every non-leader enemy kind of `data/enemies.json` as extra spawns (half of them bounties), placeable summons on the board, every equipment item, band, battle-side 机变 card and stage map card in turn, bonds from the board |
|
||
| `bonds` | 46 battles: every bond at its activation threshold (1 layer) and at its top tier (999 layers) |
|
||
| `fields` | 22 battles: every Final Assault / Hidden Core leader on a pair and a solo template (shared pool, 200 s cap) and the 联防 field with 1 and 2 helpers on the round's stage, both halves (carried HP / SP, a knocked-out operator, two leakers' enemies) |
|
||
| `matches` | 20 matches to the end in virtual time: 16 bot-only (solo 标准 / 险境 / 绝境 / 终极 × 2 seeds, co-op 2 / 3 / 4, one server-run combat match, two runs boosted to the Hidden Core), one co-op match whose human seat (AI 托管, offline) does not own 9 NORMAL chess — they fight as their 补位 stand-ins (its digest lists them per round, `standIns`) — and one whose human seat slots 自选 picks (推进之王 and prototypes) with its 调度中心 at level 5 from the first prep: its own shop draws them and its AI fields 推进之王 (its digest lists per round the 自选 shop draws and the fielded pieces, `diy`) |
|
||
| `standins` | 10 battles: every NORMAL chess record (normal and elite, 110) fielded as its 补位 stand-in (`standIn: true`: the stand-in's body, backup skill / module and kit — all 17 stand-ins, every skill a chess names for them), 12 per battle by strength band, laid out by the stand-in's position on a real stage, against the round's real wave three times over plus 8 ground enemy kinds (melee stand-ins always meet an enemy), an item each, bonds from the board |
|
||
| `diy` | battles of 自选 pieces (a DIY slot with its `diy` pick, `shared/diy.js`): every owned 6★ with an operator kit (`kits/index.js OPERATOR_KITS`) in each form of tiers 5 and 6 (normal; elite with no module and with each module) under each skill, then every prototype pick with a kit at its locked selection, normal and elite, 12 per battle against the round's real wave; a new operator kit adds its scenarios (the battle count grows with the kits) |
|
||
|
||
Battles go through the production BattleSpec path (`server/sim/spec.js`, as browsers and the server's headless fields
|
||
run them); matches construct `Match` directly with a `VirtualScheduler`. Every option is explicit, so a change to a
|
||
test-harness default never moves a digest.
|
||
|
||
What a digest ignores on purpose (it does not affect gameplay): object key order, engine unit ids (snapshot ids are
|
||
renumbered by first appearance, units are named by board uid or def id), board piece uids, the order of client events
|
||
within a tick (they are counted, not hashed) and wall-clock time. Damage / healing sums are rounded to integers and HP
|
||
to 2 decimals.
|
||
|
||
`npm test` runs the fast subset (the scenarios marked `"fast": true`: every chess record with its default loadout,
|
||
every stage and every non-leader enemy kind, every bond at its top tier, six fields, seven matches, the five stand-in
|
||
battles of the normal records, the first 自选 battle of the operator kits and of the prototypes — 62 of the 151). `GOLDEN_FULL=1` checks everything.
|
||
|
||
## Workflow
|
||
|
||
```sh
|
||
GOLDEN_FULL=1 node --test test/golden.test.js # the whole corpus (≈ 20 s with 4 worker threads)
|
||
node --test test/golden.test.js # the fast subset
|
||
npm run golden # the same comparison from the tool (all families, a short report)
|
||
npm run golden:update # recompute and rewrite test/golden/*.json
|
||
node tools/golden.mjs --twice # determinism: the corpus twice in one process, the second pass reversed
|
||
```
|
||
|
||
- **A refactor commit must never change these files.** Run `GOLDEN_FULL=1 node --test test/golden.test.js` before
|
||
committing it. If a digest moves, the refactor changed behaviour: find out why (the first differing value of `snaps`
|
||
says when two runs parted, in 10-game-second steps) instead of updating the files.
|
||
- **An intended gameplay change** (a fix, new content, a data rebuild): run `npm run golden:update` and commit the
|
||
changed files together with the change, saying in the commit message which scenarios moved and why.
|
||
- **Reviewing the diff:** every scenario is a block of its own and every unit / enemy / round is one line, so a diff
|
||
shows which scenarios moved and which values changed. A change confined to the scenarios that contain the touched
|
||
operator, enemy or rule is expected; a change everywhere (every `rngDraws`, every `snaps`) means something global
|
||
moved — the RNG draw order, the tick order, a shared rule.
|
||
- **Adding to the corpus** (a new family, more scenarios, a new digest field) changes the files by design: do it in a
|
||
commit of its own, never together with a refactor.
|
||
- A new engine hook, event or chess record does not change the digests of the existing scenarios by itself — the
|
||
hook list is frozen in the tool and the corpus is regenerated only on `golden:update` — but new data records do join
|
||
the corpus there (the roster family enumerates `data/chess.json`).
|
||
|
||
After the measured shared-stock update (DESIGN §29.8), the original stand-in / DIY seeds remain as outcome regressions even when they field no such operator. Companion seeds `coop2-NORMAL-1-coverage-standins` and `coop2-NORMAL-5-coverage-diy` exercise those full paths; the corpus now contains 287 scenarios.
