# Frontend legacy parity
This document records the reusable browser fixture and the visual contracts that
are enforced while the PHP frontend is moved to the Vue applications. The
workspace-level `docs/ref-core2026-mapping.md` remains the source of truth for
the end-to-end PHP-to-core2026 mapping.
## Canonical browser fixture
`tools/frontend-legacy-parity/fixtures/canonical.ts` contains deterministic,
non-secret gateway, session, map, and hall-of-fame data. The fixture uses a
synthetic `ga_` game access token so the game router guard follows the same
authenticated path as a real session without contacting a live database.
The test suite intercepts only the tRPC operations required by each screen and
fails on unknown operations. It also serves the checked-out reference image
tree instead of replacing images with layout-neutral placeholders.
`public-gaps.spec.ts` adds bounded fixtures for nation betting and the public
NPC list, including mutations and recoverable API failures.
`tournament-betting.spec.ts` covers the separate tournament and tournament
betting routes, including a recoverable failed bet.
`reference-rankings.mjs` records the authenticated PHP 명장일람 and public
명예의 전당 computed DOM without embedding the reference password.
`battleSimulator.spec.ts` covers the authenticated simulator with and without
an owned general. `battleSimulatorRef.spec.ts` can additionally exercise the
live reference page when its URL, user, and ignored password file are supplied.
Run the suite from the core2026 repository root:
```sh
pnpm test:e2e:frontend-legacy
```
When another worktree occupies the default ports, set
`FRONTEND_PARITY_GATEWAY_PORT`, `FRONTEND_PARITY_GAME_PORT`, and
`FRONTEND_PARITY_GAME_URL`. `FRONTEND_PARITY_ARTIFACT_DIR` retains the
tournament and betting screenshots.
Run the focused simulator fixture with:
```sh
pnpm --filter game-frontend test:e2e:battle-simulator
```
The optional reference check uses `REF_BATTLE_SIM_URL`, `REF_USER_ID`, and
`REF_USER_PASSWORD_FILE`. The password is read inside the test and is never
written to screenshots or reports.
The suite starts both applications at their public prefixes:
- gateway: `http://127.0.0.1:15100/gateway/`
- game: `http://127.0.0.1:15102/che/`
Chromium uses the same locale, timezone, device scale factor, and color scheme
for desktop and mobile checks. Tests assert geometry, computed typography and
texture URLs before checking hover, focus, menu, login mutation, session
storage, route guards, and image loading.
## Enforced contracts
| Screen | Ref entry point | Current automated contract |
| -------------------- | ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |

| survey | `hwe/v_vote.php`, `hwe/ts/PageVote.vue` | 1000/500px fixed container, blue title/green table textures, list/detail/results/comments, selection/focus/hover, submit and retained-selection API error |
| nation personnel | `hwe/b_myBossInfo.php` | fixed 1000px document at both viewports, chief icon columns, officer/permission/city/kick controls, role redaction |

| battle simulator | `hwe/battle_simulator.php` | centered 1000px desktop document, 500px responsive stacking, independent/current presets, owned-general import gating, fixed-seed result/logs, retained input after API error |
| NPC policy | `hwe/v_NPCControl.php` | 1000/500px form and priority-list geometry, walnut/green textures, dynamic zero hints, drag/focus/tooltip, successful save and permission failures |
| tournament | `hwe/b_tournament.php` | fixed 2000px canvas, 16×125px bracket, eight 250px group tables, walnut texture, 1024px overflow, hover/focus |

The global game baseline is black, white, Pretendard 14px. Legacy texture
helpers intentionally follow `common.orig.css`: `bg0` is walnut, `bg1` is
green, and `bg2` is blue. Shared `PanelCard` uses the same walnut body and green
header so screens that still use the common component no longer inherit the
discarded Galmuri/parchment visual system.
The survey fixture covers both the poll list and an open detail. Its result
rows are visible before the current general votes when the poll uses the
legacy-compatible `after_vote` mode. The mutation fixture covers voting and
comment submission, while the error fixture confirms that a failed vote keeps
the selected radio option so the user can retry.
## Route coverage rule
Adding or changing a frontend route requires:
1. a verified ref entry-point mapping in the workspace mapping document;
2. deterministic tRPC fixture data for the visible state;
3. desktop and 500px/mobile geometry and computed-style assertions;
4. actual Chromium interaction checks for every visible interactive state;
5. natural image dimensions and `object-fit` checks where images affect layout.
Pixel snapshots may be added after these structural assertions pass. Dynamic
regions must not be hidden merely to make a pixel threshold pass.
To refresh the PHP ranking evidence after building the ignored reference
webpack assets, run:
```sh
REF_RANKING_URL=http://127.0.0.1:3400/sam/ \
REF_RANKING_PASSWORD_FILE=/path/to/ignored/user1_password \
REF_RANKING_ARTIFACT_DIR=/path/to/ignored/artifacts \
node tools/frontend-legacy-parity/reference-rankings.mjs
```
The nation office suite can be run independently:
```sh
pnpm --filter @sammo-ts/game-frontend test:e2e:nation-offices
```
Set `PLAYWRIGHT_FRONTEND_PORT` when the default `15120` port is occupied. For
reference collection, `tools/frontend-legacy-parity/reference-nation-offices.mjs`
records desktop/500px computed DOM and screenshots from the PHP service without
changing its product code.
The NPC policy suite and its reference collector can be run independently:
```sh
PLAYWRIGHT_FRONTEND_PORT=15126 \
pnpm --filter @sammo-ts/game-frontend test:e2e:npc-policy
REF_PARITY_USER=refuser1 \
REF_PARITY_PASSWORD_FILE=/path/to/password-file \
REF_PARITY_BASE_URL=http://127.0.0.1:3400/sam/ \
node tools/frontend-legacy-parity/reference-npc-policy.mjs
```
The collector writes desktop and 500px screenshots plus computed DOM JSON only
when `REF_PARITY_ARTIFACT_DIR` is set. It requires an existing reference general
owned by the supplied account and never accepts a password on the command line.
The current-city reference can be collected independently with
`tools/frontend-legacy-parity/reference-current-city.mjs`. It requires
`REF_PARITY_PASSWORD_FILE` and accepts `REF_PARITY_URL`, `REF_PARITY_USER`, and
`REF_PARITY_ARTIFACT_DIR`; the password is read from the ignored secret file
and is never written to the artifact. The matching core fixture is
`app/game-frontend/e2e/inGameInfo.spec.ts`, which writes its computed DOM and
screenshot only when `CITY_PARITY_ARTIFACT_DIR` is set.
For a review run that also writes full-page screenshots, create an ignored
artifact directory and set `FRONTEND_PARITY_ARTIFACT_DIR` before invoking the
suite. The ordinary CI run does not write screenshots after successful tests.
