- Replace the square star field with a wide (width × height) field whose
aspect matches the map plate, so the fully-zoomed-out galaxy fills the
plate instead of letterboxing; recompute zone edges for equal-area thirds
under the new diagonal CDF.
- Add fitPadded() in SystemChart.js and use it in GalaxyView.js to frame
the galaxy as a true rectangle fit with a plate-pixel margin, replacing
the old world-unit padding that left stars on the plate edge.
- Rework the JumpNetwork spanning-tree heuristic to "save the stranded
first" (attach the candidate with the fewest unvisited non-barren
neighbors) and strengthen the repair pass: never attach to barren nodes,
guard swaps against cycles via inSubtree(), and add a last-resort
fallback that preserves strong connectivity.
- Update tests (galaxy.test.mjs, system-chart.test.mjs) for the field
bounds and the new fitPadded behavior; refresh README, PROJECT_NOTES,
and data comments to document the 2:1 field and platePadding knob.
- Shrink the roster from 200 to 60 systems and drop spiral arms / core bulge for a uniform-in-area sparse disk (data/galaxy.json)
- Turn the jump network into a pure spanning tree (shortcuts off): exactly one route between any two systems, barren systems become single-gate dead-end leaves
- Remove the rendered Star entity; non-home system centers are now empty space with the star kept only as invisible dossier flavor
- Gate anchors restricted to planets (stations no longer anchor) and every non-barren system guaranteed ≥1 planet so a buildable world always exists
- Give barren dead ends 1–2 asteroid clusters drifting inside their gate's level-1 tether as the stop's only payload
- Bump save format to 2 and reject legacy format-1 saves with a clear toast message
- Update tests, docs, and README to reflect the maze layout, leaf dead ends, empty centers, and new barren cluster rules
- Galaxy shrunk to 200 systems (data/galaxy.json) — always fully known,
generation ~15 ms; roster/content two-level design unchanged.
- Object composition replaces planetCount (data/systems.json → objectCount):
10% barren (jump-gate-only), else 2/3/4/5 objects (planets + free-space
stations) at 15/30/30/15. One unified roll (rollSystemComposition) shared
by the content generator and the frame pass.
- Barren systems: no planets, no stations, no asteroid clusters; their
single gate sits on the star→destination ray at barrenDistance (8192 px).
Strong connectivity keeps them reachable.
- Jump gates are DORMANT by default: every gate record carries
active:false, the entity renders dim with a still field. Activation is
the seam for the tether mechanic (an activated gate anchors a level-1
tether). data/gates.json gains barrenDistance.
- Frame diversity (js/galaxy/PlanetFrames.js): one galaxy-wide pass spreads
(class, frame) across the galaxy — fixed spatial order, least-used face
among already-assigned nearest stars, seeded tie-breaks. Stamps
planet.frame + content.homeFrame, read by GameScene.
- Tests: dev/frames.test.mjs added; jumps/galaxy/discovery/jumpgate/asteroids
suites updated to the new rules (composition buckets, barren gates,
active flags, frame determinism/spread, 5-object max, index clamps).
- Docs (README, PROJECT_NOTES) and stale 40k references updated.
- Introduce data/gates.json + js/galaxy/JumpNetwork.js: a strongly-connected, degree-limited spanning tree over the nearest-star graph (plus local shortcuts) so every system holds 1–3 gates, all jumps are local, and no system is closed or trapped
- Place each gate on the tether circle of an anchor (planet / space station / home world), facing its destination star; enforce radius band, clearance from anchors, and gap between gates in SystemGenerator.layoutGates
- Add the JumpGate entity (procedural twin-pylon portal) with the same solid contract as Planet/Station, discoverable in cyan, listed in the HUD dossier; wire into GameScene solids + discovery
- Guarantee every system holds at least one gate anchor (barren systems get a deep-space station); cap the home system at 3 objects so it fits the tighter band
- Rework solar-system layout to a full pairwise band [minSpacing, maxSpacing] with rotation tuned toward gate bearings; update tests and docs accordingly
