Battle-mechanics data and predicates in views/utils/combat/ — OASW (anti-sub first strike), AACI (anti-air cut-in), AAPB (anti-air propellant barrage) and special attacks. Use when editing anything under views/utils/combat/ or views/utils/{aaci,oasw,aapb,sp_attack}.ts, when adding or validating ship/equipment eligibility conditions, when asked to "check game data" / "new ships were added" / "update combat conditions", or when a battle prediction looks wrong for a specific ship.
Quest tracking — the assets/data/quest_goal.cson schema and the engine that consumes it (views/redux/info/quests/**, views/redux/actions/quest.ts, views/redux/middlewares/quests-cross-slice.ts). Use when editing quest_goal.cson, adding or fixing quest tracking, adding a new subgoal filter, or when asked which quests are untracked.
Working with kcsapi game-API payloads in redux — typing action creators, sourcing real response-saver fixtures, writing slice/middleware tests, and avoiding `as` / `any`. Use when editing views/redux/**, adding an API response action, writing or fixing tests under __tests__, needing a real API payload sample, or inspecting api_start2 master data.

| description | Regenerating fcd data, in particular ship-avatar marginMagic values via fcd/gen-shipavatar.js. Use when editing anything under fcd/, when asked to regenerate or fix ship avatar crops, or when ship portraits in the fleet view are framed wrongly. |
fcd/gen-shipavatar.js generates the marginMagic values in fcd/shipavatar.json, which
control how each ship's remodel art is cropped into an avatar.
banner--method banner (the default) substantially outperforms --method face:
banner: the game's 160x40 banner art is the game's own face-framed crop of the remodel
art. The script registers banner -> remodel via ORB keypoints + RANSAC (scale + translation,
no rotation); marginMagic is then linear in the transform (tx, s), and the two-feature
least-squares fit implicitly finds the anchor (~x = 101px in the banner).
Full run: R^2 = 0.82, MAE = 0.059, 4 failures out of 1724.
The banner frame is removed by a cross-banner pixel-identity mask: background pixels are byte-identical across banners of the same stype, so >= 4 matches within +-2 marks background; the pool falls back to all banners for stypes < 6. Note that banner character scale varies per ship (2.15x–2.98x), so plain template matching fails; whole-banner matching also fails, because the banner band covers more vertical content than the remodel strip.
face: lbpcascade_animeface. Pad 48px first (faces touch the strip edges) and do not
use equalizeHist (the transparent-black background kills it).
R^2 = 0.67, MAE = 0.073, 253 failures, with catastrophic outliers.
node fcd/gen-shipavatar.js --start2 <api_start2 capture> # default: fill missing/partial only
node fcd/gen-shipavatar.js --start2 <capture> --overwrite # replace all
node fcd/gen-shipavatar.js --start2 <capture> --write # merge into fcd/shipavatar.json
cd fcd && node build.js
The api_start2 capture comes from the response-saver — see the redux-api-testing skill.
Review the results in fcd/.cache/review.html before using --write.
fcd/report-diff.js produces a before/after comparison against git HEAD with visual crops in
fcd/.cache/diff-report.html.
Visual spot-check trick: bitblt the source-space window crop (x = m * 80 / (83/182),
w ~ 325) out of the remodel PNG and view it.
The fit is calibrated against the current fcd/shipavatar.json. Once machine-generated values
are committed, that ground truth is polluted — if you recalibrate, fit against a hand-tuned
revision instead:
git show <hand-tuned-rev>:fcd/shipavatar.json
203.104.209.71 is dead — use w01y.kancolle-server.com.avatar.tsx's (height / 176) * 182.opencv-wasm (has ORB / BFMatcher / CascadeClassifier but no
estimateAffinePartial2D, hence the hand-rolled RANSAC) and pngjs.Applied 2026-07-24 with overwrite-all + banner method: 862 entries (up from 465), build version 2026/07/24/03. Both methods independently flagged the same hand-tuned values as wrong (Ooshio 0.877 -> 0.65, Michishio, Akatsuki Kai, Kongo 0.335 -> 0.541, Shiratsuyu Kai); visual crop checks confirmed the machine values were correct, so nothing was reverted.
