- Rebalance the three cargo hold upgrades (8/12/16) from a credits-only sink to a mixed cost of credits and minerals, so expanding the hold draws on both trade income and the mining economy.
- Update research descriptions, build data, tests, docs, and code comments to reflect the new two-resource costs.
- Introduce data/research/cargo.json: a 3-node chain (8 → 12 → 16 bays) where each node is a blueprint that unlocks the matching ship-hold build
- Add `build` gate field to ResearchModel.js (attachBuildGates) so a node can require a named build to be completed before it becomes researchable, composing with the existing quest gate
- Wire both gates in GameScene and ResearchWindow so node availability, lock notes, and the RESEARCH button reflect quest + build state
- Gate cargo_bay_8 on the special_delivery quest; cargo_bay_12/16 on Improved/Advanced Mining Storage builds
- Update builds.json to require the corresponding research nodes for cargo-bay-8/-12/-16
- Add comprehensive tests covering the cargo tree structure, pure DAG availability, live gate composition, and build-side lock-step
- Add an optional node quest field so research techs can require a named quest's reward to be claimed before becoming available.
- Wire the scene's live questClaimed predicate into ResearchModel.attachQuestGates and the research tree loaders so node states, the RESEARCH button, and LOCKED readouts all honor the gate.
- Gate mining premium_arm and advanced_storage on the Special Delivery quest, and add data/test coverage for the quest-gate behavior.
- Add `premium_arm` and `advanced_storage` research nodes (Tier 3) to the mining tech tree, each gated by its Tier-2 parent.
- Add `mining-arm-premium` (4.0 minerals/s) and `mining-storage-advanced` (500 capacity) ship builds in data/builds.json.
- Update existing Tier-2 nodes to declare their new children in `unlocks.research`.
- Extend test suites for the two new research nodes, their build wiring, cost/affordability, DAG layout (3 rows), and availability gating.
- Use fixed short button copy for the gates tech ("Unlock Jumpgates") and mining nodes (drop "Mining" prefix) since the tree node has no room for system names or category words
- Raise detail panel height and widen node/button plates so long descriptions and status labels stop bleeding past plate edges
- Add word-wrap to the unlocks line and trim redundant status prefixes ("RESEARCH CONSOLE STANDBY", "PROJECT COMPLETE")
- Fix ice-surface-01 video reference in landing.json (was pointing at rocky-surface)
- Add OAC speech clips and ice surface video asset; update planets.psd
- Tighten tether research descriptions to match the new short-copy style
- New `data/research/mining.json` tree (Improved/Advanced Mining Arm, Improved Storage) as blueprints that unlock matching builds
- Three new ship-scoped builds in the console's Mining tab: mining arm rate 1.5/2.0 minerals/s and hold cap 350; MAX-guarded effects applied to `ship.stats`
- Tether Level 3 promoted from research-direct effect to a build (tether-l3) gated on L2 tether, consistent with L2 blueprint pattern
- `BuildState.isBuiltAnywhere` + `isShipScoped` so ship upgrades count as built wherever the ship lands (no re-buy), records still key the planet
- `GameScene._restoreMiningUpgrades` re-derives ship mining stats from build records on load; `_applyMiningUpgrade` handles rate/capacity with toasts and HUD refresh
- New procedural icons: tether3, mining, mining2, storage
- Updated tests (builds, research-builds), diagnostics (BuildDiag v4), docs, README, manifest
- Reduce maxLevel from 12 to 3 in data/tether.json
- Remove the tether_l4 entry from exploration.json; tether_l3 now has empty unlocks
- Update research-builds and tether tests to reflect the shorter chain (3 layout rows, level checks for 1–3 only)
- Revise PROJECT_NOTES.md to describe the 3-level progression
- Change radiusGrowth from 1.25 to 2.0 so level N doubles the previous
level (L2 = 10240, L3 = 20480, L4 = 40960 px)
- Update all data descriptions, docs, and test defaults to match
- Add refreshHudTetherLevel() in SurfaceScene so the HUD line re-decodes
when a tether build completes while on-surface
- Rename rocky-planet-02 asset (typo fix), add 03-a/03-b variants,
point rocky frames at indices 6–8 in planets.json
- Add dev/tether-flow harness to exercise the full L2 build flow end-to-end
- 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
