- `_applyResearchEffects` now receives the node id explicitly instead of
reading `node.id`, which is undefined (the id is the key in the tree's
`nodes` map, not a field on the object) — this was silently skipping
`activateGates` so researched jumpgates stayed dark
- Add `systemIdOfGatesNode()` as the pure inverse of `systemNodeId()` for
the gates node, with round-trip tests
- Reconcile gate activation in `_onEnterSystem()`: if the gates tech is
already unlocked, re-run `_activateSystemJumpgates` (idempotent) so a
missed activation self-heals on the next entry/jump/reload
- Make `_activateSystemJumpgates` idempotent by tracking fresh keys and
early-returning when everything is already online
- Add `navPoints()` and `navChart()` to SystemCategory.js as pure,
testable cores for the jumpgate unlock condition (discovered/missing
split over all NAV points)
- Add `js/dev/NavDiag.js` with `orbitNav()` / `orbitNavBrief()` console
commands that print the live NAV chart and which objects are still
undiscovered, installed by `main.js` on every page load
- Update `data/landing.json` to reference the correct gasgiant surface/shop
videos for slot 03
- Add tests for `navPoints`, `navChart`, and `systemIdOfGatesNode`
- Document the activation wiring bug, the `orbitNav()` diagnostic, and the
new pure functions in PROJECT_NOTES.md
- Introduce a dynamic "system" research category built at runtime with two techs: `{System} Map` (granted on entry) and `Unlock {System} Jumpgates` (researchable once every NAV point is discovered).
- Wire gate activation through the research effects seam so completing the jumpgate tech activates the system's gates plus linked return gates, anchors level-1 tethers at each activated gate, and saves/restores via a new `activatedGates` set.
- Extend ResearchModel with optional tree hooks (`available`, `lockNote`) so dynamic categories can gate research on live world state without adding static requires.
- Add map and gate procedural icons, update tests for the new category contract and icon roster, and document the system category in project notes.
- Introduce the BUILD deck slot on planet surfaces: full-screen BuildWindow
(looping feed video, category tabs, build list, dossier + cost + BUILD
button) backed by pure BuildModel/BuildState rules
- Move tether level 2 from a research effect to a one-off planet build
(200 minerals, 20 s, requires L1 tether on the world); home world starts
with tether-l1 pre-installed as a rule re-asserted after load
- Add `node dev/server.mjs` static server sending Cache-Control: no-store to
stop browsers heuristically caching ES modules (the "new data + old JS" bug)
- Fix world-name casing leak: CommsPanel keeps canonical spelling in the
landing payload; GameScene.startLanding normalizes via WorldNames.canonicalPlanetName
so name-keyed build/tether lookups match
- Add in-game diagnostics (orbitDiag/orbitDiagBrief), dev/build-check.html
self-check page, and Node tests for builds, world names, and save staging
- Persist builds (built records + in-flight remaining time) in the save bank;
tick on the game-loop clock so a build survives takeoff mid-build
- Define the two-sided unlock contract: research nodes declare `unlocks.builds`/`unlocks.research`, builds declare `requires` as "category/node id" (authoritative gate); ResearchModel exposes `unlocksOf`, `buildDefs`, `unlockIssues`, `buildIssues`
- Add `tether-l2` build entry (planet/station targets, credits+minerals cost, level-2 tether effect) and link it from `exploration/tether_l2`
- Show an UNLOCKS line in the research dossier so the console surfaces what a tech opens
- Extend dev/research-builds.test.mjs to validate both sides of the gate and the new model helpers
- Update data/builds.json, research.json, exploration.json `_comment`s and PROJECT_NOTES to document the contract
- Full-screen RESEARCH window: looping archive feed, category tabs, branching
DAG tech tree (top-down layout), per-tech dossier + RESEARCH button, deck
progress bar
- Pure rules layer (ResearchModel / ResearchState) is Node-testable; the
window is a passive view and GameScene owns effects, toasts, and saves
- First category **Exploration** (Tether Level 1–4, Tether Anchoring, Signal
Amplification) lives in data/research/exploration.json; adding a category
= one JSON file + one registry line + one manifest line
- Effects seam: `tether.level` grows the home tether via TetherField.setLevel;
`capability` flags land on scene.researchCapabilities for future systems
- Save/restore round-trips an in-flight project (remainingMs captured at save,
startedAt rebuilt on load); old saves without research still load
- Dev tooling: dev/cdp-shot.mjs (CDP screenshot with readiness wait),
dev/research-shot.html/.mjs (boots the console + starts a run for a shot)
- Assets: gasgiant planet frame 03, takeoff/landing clips, research-computer
feed; planets.png/.psd updated
