Claude 748cb8927e Rebuild the map chrome against the Star Citizen starmap
Until now this was built from memory — the reference site is blocked by this
environment's egress policy, so the resemblance was asserted rather than
checked. Five screenshots of the real thing arrived, and this is what
comparing against them changed.

Labels say what a thing is, not just what it is called. Every label is now
two lines: the name, then its type in smaller, wider-tracked, dimmer
capitals. This is the single most characteristic element of the reference
and it appears in every frame of it. It also settles a real ambiguity — in a
map that mixes scales, "Orion" is an arm, a nebula and a constellation, and
nothing about a bare name said which one a label pointed at.

For stars the type line distinguishes "System" from "Star", which is the one
thing it can say that the map could not otherwise show: which points are
somewhere you can actually go.

The system view had no body labels at all, where the reference labels every
planet. It does now, which turned out to need two supporting changes. The
overlay had only ever added and removed labels, never moved them, because
stars do not move; planets do, so an existing label is now repositioned
rather than left where the body used to be. And the inner four planets
printed on top of each other in exactly the clump the star labels were
already spread to avoid — so that logic is now shared rather than
duplicated, with system bodies ordered outermost-first. Closing in reverses
it by itself: the outer orbits leave the frame, their labels drop, and the
inner planets take the space.

The chrome follows the reference's layout. The scale ladder is a row of
chamfered tabs at the top left rather than a vertical list of diamonds at
the middle left, and a nameplate across the top centre says what the view is
holding. The centre reticle is a hexagon, which is how the reference locks
onto a body, and stays distinct from the rectangular panel chrome.

Not copied: the ARK/RSI logos, wordmarks, and the bottom-right tool tabs.
The first two are someone else's brand, and the third would be four tabs
opening features this app does not have.

Two e2e assertions moved off bare text matches onto the readout panel's own
title. The nameplate names the same thing the panel does, so "is 'Local
Stars' on screen" became ambiguous — the assertion, not the design, was what
had to give.

Claude efa9e4084a Draw the whole catalogue, and build the aggregation the rest would need
Two things, one verified and one that cannot be.

The render budget is now the whole catalogue: 68388 stars, one instanced
draw call, which is what a GPU should be asked to do. The budget itself
stays, because the catalogue is meant to grow past what any machine should
draw at once — Gaia alone could contribute a million — and at that point
the selection is what keeps the field legible rather than a grey wash. A
`?stars=` override handles the machines that cannot, including the
software rasterizer the end-to-end suite runs against, whose frame rate is
two orders of magnitude below a real GPU's and which was measuring the
rasterizer rather than the app.

The aggregation is the second thing, and none of it has run. Every ESA,
NOIRLab, SDSS and Euclid endpoint is unreachable from here — only GitHub
raw is, which is why HYG and OpenNGC are the current sources. So this is
infrastructure and a Gaia query written against the published DR3 schema,
not data.

What the framework encodes is that these surveys are not interchangeable.
The distinction is not size but whether a catalogue knows how far away its
objects are, because a 3D map cannot place a star it only has a direction
for. Gaia is the only one of the five that can add stars here, because it
is the only one that measures parallaxes. DECaPS2 has fifty times Gaia's
object count and photometry alone — not one of its 3.32 billion objects
can be placed in depth. Euclid's bulge is 8 kpc away, where a parallax is
microarcseconds; its contribution would be imagery. SDSS-V and SAGA are
keyed to stars something else already places, so they enrich rather than
extend. Those roles are recorded as data the ETL prints, not as prose that
can drift.

Overlapping catalogues are reconciled on direction rather than on 3D
proximity, which is the one non-obvious part. Two surveys agree on a
star's direction to within an arcsecond and disagree on its distance by
tens of per cent, so a star at 200 pc is 50 pc from itself between
catalogues while being unmistakably the same object. Matching in 3D would
need a tolerance so loose it swallowed real neighbours. The better
parallax wins where both reach; where only one does, the star stays.

Names become dense-with-holes with a source dictionary, because a survey
catalogue has no proper names — writing "Gaia DR3 4472832130942575872"
once per star would cost 25 MB per million to repeat what two adjacent
fields already say. An empty entry costs three bytes and is regenerated on
load. The Sun needed its own case in the merge: it sits at the origin, has
no direction to compare, and appears in every catalogue.

Claude 29fd92d118 Widen the star catalogue, and separate what is drawn from what is known
The map held 8750 stars within 50 pc and rendered 371 systems. Both were
lower than they needed to be, for different reasons.

The star catalogue was capped by its own encoding as much as by the
cutoff: one JSON object per star, eight key names repeated each time, 157
bytes a star. At the range HYG actually reaches that is 17 MB to download
and parse before the first frame. So the numbers move into two binary
column stores — positions in stars.bin, which the GPU is handed verbatim,
and id/magnitude/colour/spectral index in stars-meta.bin — and the JSON
keeps only the strings, with 2600 distinct spectral classifications
collapsed to a dictionary. The layout is defined once, in star-catalog.ts,
and the ETL and the app both use it, so the writer and the reader cannot
drift.

The cutoff then goes to 250 pc: 68388 stars, 7.8x as many for 1.7x the
bytes. That is where HYG's measurements stop rather than a round number —
98.6% of its rows are Hipparcos, whose parallaxes are good to about a
milliarcsecond, so beyond 250 pc it would be plotting noise.

Drawing all of them is a separate question from knowing them, and it is
answered separately. The field draws a budget: every star inside 25 pc,
because the nearest are faint red dwarfs and Proxima Centauri is magnitude
11, then the brightest of everything beyond. Search, navigation and the
planet cross-reference still see the whole catalogue. A real GPU would
draw all 68388 without noticing; the budget is for the machines that would
not, and it is one constant.

Systems were limited by something else entirely. The archive data already
shipped named 4735 host stars and only 388 resolved, because the rest lay
outside a 50 pc catalogue — and the cross-reference kept only its own
result, so redoing it meant re-downloading an archive that is not
reachable from here. Host coordinates are now stored with each planet, and
the match is re-resolved at build time against whatever catalogue the run
produced. Even name matching alone, which needs no coordinates and so
works on the records already shipped, rescues 335 planets across 238
systems: 371 renderable systems become 609.

Two selection rules were tuned for a 50 pc bubble and no longer fit.
Tethers followed the Sun's nearest neighbours, which are a speck at this
range, and now follow the brightest; labels were ranked by proximity,
which named whatever sat nearest the middle of the screen, and are now
ranked by brightness — so the view names Canopus, Achernar and Spica
rather than a clump of catalogue designations.

Claude be19d9cbcc Keep the star visible at the distance that frames its system
Framing the whole system pushed the camera far enough back that the star
at the centre became a speck — about a pixel across for the Sun.

The cause is a constraint that cannot be tuned away. A star is sized
against its system's innermost orbit, because it must never swallow its
closest planet, while the camera is placed to frame the outermost ring.
In the solar system those differ by a factor of a hundred: at the distance
that fits Pluto in view, a disc that stays clear of Mercury is a pixel
across. No radius satisfies both, because the information genuinely does
not fit on one screen at that zoom.

So the disc stays honest to the orbits and the halo carries the
visibility. Light is not a surface: a glow that reaches past the innermost
orbit says the star is bright, not that it is large. Its extent is still a
multiple of the star — so a compact system keeps exactly the corona it had
— but floored against the framed radius, which is what the wide systems
needed.

The disc grows a little too: it may now reach 45% of the innermost orbit
rather than 35%, which still leaves clear space between the star's limb
and the closest orbit.

Also makes createGlowSprite take the extent it will draw rather than a
radius and a multiplier. The two were only ever multiplied together, and
how large a star's halo should be is not a property of the star — it
depends on how its system is framed, which is a decision that belongs with
the framing.

Claude ac296f5133 Derive a surface for every body that was never photographed
Fifteen bodies here have a real photograph. Every exoplanet does not, and
never will on current instruments — none has ever been imaged — and nor do
several of the solar system's own moons. Those all shared one crude
stand-in: a few noisy bands tinted by category, cached per colour, so
every exoplanet in the app was literally the same picture.

They now get a surface reasoned from what has actually been measured.

The chain is standard at every link. A host star's luminosity comes from
its catalogued apparent magnitude and its parallax distance — that pair is
exactly an absolute magnitude — plus a bolometric correction for its
spectral class. The correction is not optional: an M dwarf radiates most
of its light in the infrared, so its visual magnitude understates it more
than tenfold, and M dwarfs are what most nearby planet hosts are.
Luminosity and the semi-major axis then give an equilibrium temperature,
mass and radius give a bulk density, and size, temperature and density
together give a class of world.

Checked against the solar system the temperatures land on Earth 255 K,
Jupiter 112 K, Neptune 46 K, all within a kelvin or two of published
values, and 51 Pegasi b comes out at 1227 K against a published 1200.

Each class carries a palette reasoned from its chemistry — methane absorbs
red light, which is why the ice giants are blue — and a structure: zonal
bands for a body with a fluid envelope, because a rapidly rotating
atmosphere organises into them, and fractal terrain for one with a solid
surface. Polar caps grow and shrink with the derived temperature, which is
the clearest visible consequence of the whole chain.

The generator samples three-dimensional noise along the sphere rather than
a flat field, so there is no seam to stitch at the antimeridian and no
pinching at the poles, and it writes into a byte array rather than a
canvas — a pure function, testable, with no 2D context to be unavailable.

Two things the derivation cannot do, both stated on screen next to the
measurements it rests on. Equilibrium temperature ignores greenhouse
warming and internal heat, so Venus comes out at 300 K against a real
surface of 737 K and Io, kept molten by tides, classifies as ice. And
these are illustrations: reasoned, but not observations.

Claude 2e525fb5c3 Open the map out to the whole Milky Way
The map stopped at the catalogued 50 pc around the Sun — 0.33% of the
Galaxy's width — and looked like a point cloud with a search box.

Adds the galactic scale above it and the heads-up display the reference
map is built from.

The Galaxy is not a third coordinate space. It is the same parsec space
four orders of magnitude further out, so the model and the star field
crossfade against camera distance instead of switching, and the Sun stays
where it really is: 8.18 kpc out, on the Orion Spur, between the
Sagittarius and Perseus arms. The depth range scales with that distance —
one fixed near/far pair cannot both fly into a star and hold the Galaxy.

The structure in shared/astro/galaxy.ts is measured: the directions of the
centre and the north galactic pole, which fix the disc's 63 degree tilt
against the celestial equator; the Sun's galactocentric distance; and a
radius, azimuth and pitch angle per arm. The particles scattered around it
are not, and cannot be — dust hides the disc, so no catalogue holds the
Galaxy's stars. The view says so, and the model fades out before the
camera reaches the 50 pc where the real stars are.

The rest is the look: polar grids lying in the galactic plane with drop
lines from the Sun's neighbours, a scale ladder, a readout panel, range,
reticle and frame brackets. Two things had to give way for it. The
deep-sky shell is the sky as seen from here, so it dissolves rather than
letting the camera fly through a wall of nebulae, and so does the skybox,
which is a photograph taken from inside the thing now being viewed from
outside. Labels are picked by screen separation rather than distance
alone: the Sun's fifteen nearest neighbours are all inside four parsecs
and printed as one unreadable clump.

Claude 2293585940 Put orbits and stars in the same reference frame
The app's two sources disagree about which frame they are in, and nothing
reconciled them. HYG star positions are equatorial J2000 — that is what
raDecDistanceToXyz produces and what the galaxy view renders directly. Orbital
elements come from JPL Horizons, whose default reference plane for element
output is the ecliptic, and the ETL never overrides it. The two are tilted 23.4
degrees apart, so the orbits sat that far off the sky they are drawn against.

Confirmed rather than assumed, from both ends: the Horizons request in
lib/horizons.ts sets no REF_PLANE, and the resulting solar-system inclinations
are 0 to 17 degrees with Earth exactly 0.00 — which is only true of the ecliptic,
since Earth's orbit defines it.

eclipticToEquatorial now rotates orbit positions into the scene frame, so a
direction means the same thing in the galaxy view and the system view. The
rotation is about the vernal-equinox axis, which both frames share.

That exposed a presentation problem the old code had been hiding. The renderer
mapped the propagator's z straight onto the scene's vertical, which silently
redefined the frame but did make systems render flat. In a properly equatorial
scene, orbital planes lie 23.4 degrees off the scene's own axes, so a system
would be presented edge-on. Rather than rotate the world back into a comfortable
pose — which would only put the orbits at odds with the sky again — the camera
now settles relative to the orbital plane: a three-quarter view about 37 degrees
off the ecliptic normal. The arrival still begins along the approach direction
and swings round as it settles, so the transition stays continuous, and the
framing is now the same every time rather than inherited from wherever the
camera happened to be.

Tests: 247 passing, up from 237. The frame tests are the discriminating kind —
Earth's orbit must lie perpendicular to the ecliptic pole rather than to the
scene's vertical, and must reach 23.4 degrees of declination a quarter orbit on,
where it used to read zero. Verified in a browser against Sol and Gl 357.

Claude f241b093eb Draw the 1509 exoplanets that were being silently dropped
The system renderer required both a semi-major axis and an eccentricity before
it would place an exoplanet, even though resolveOrbitalElements already defaults
every other missing element. The archive publishes an axis far more often than
an eccentricity: 3895 records have one and only 2386 have both, so 1509 planets
were dropped for want of a value that can simply be assumed.

A missing eccentricity now defaults to 0, a circle. That is the conventional
assumption for an orbit whose shape has not been constrained, and it is the only
honest option available, since the axis alone says nothing about elongation.

The effect is not subtle. 18 systems gain planets, and seven of them previously
rendered as a bare star with nothing around it at all: Gl 357 goes from zero
planets to three, HD 176986 likewise. Beyond the effect today, a user could
already reach one of these planets through search and its detail page, then jump
to its system and find it missing from the very system it belongs to.

isPropagatableOrbit replaces the old inline guard and also rejects what the old
one never checked: a non-positive axis, and an eccentricity of 1 or more. Those
are escape trajectories that no ellipse describes, and propagating them anyway
does not throw — it yields NaN, which reaches the vertex buffer and poisons the
geometry's bounding sphere, disabling culling for the whole object rather than
just the bad orbit. Being a type guard, it also lets the caller drop a seven-line
field-by-field copy of the orbit.

Fixes a label leak found while verifying this in the browser. Galaxy star labels
were being cleared on entering system space but immediately recomputed, because
the tick gated them on `currentStarId`, which is not assigned until the arrival
flight finishes a second later — so parsec-scale names sat pinned over the
system. Both label and orbit updates now gate on which group is actually visible,
which is true throughout the transition rather than only at the end of it.

Tests: 185 passing, up from 171. Verified in a real browser: GJ 1151 draws the
orbit and marker it gained, and no labels survive into the system view.

Claude 8d8c65bdb2 Propagate exoplanets with their real orbital period
Every exoplanet was propagated with gmForParent(undefined) — the Sun's
gravitational parameter — so the whole catalogue orbited as though each host
were exactly one solar mass. Most hosts are red dwarfs far lighter than that,
and a heavier central mass pulls harder and shortens the period, so their
planets were whirling round much too fast: TRAPPIST-1 is 0.09 solar masses, and
its planets were completing an orbit in roughly a third of the true time.

pl_orbper was already in the TAP query and was being discarded on the way into
the record. It is now kept, along with st_mass. A period and a semi-major axis
together pin the host's gravitational parameter exactly, via GM = n^2 a^3 — no
stellar model, no assumption, just the inverse of the orbitalPeriodDays helper
that was already there.

resolveGravitationalParameter picks the best available source: the measured
period, else the published host mass, else one solar mass as before. A derived
value implying something outside 0.01-150 solar masses is rejected and falls
through, since a period and axis taken from disagreeing solutions would
otherwise send a planet spinning at a visibly absurd rate.

Note the direction of the error, which is the opposite of what it looks like:
assuming a *heavier* host than reality makes a planet orbit *faster*. A test
pins it, and caught me stating it backwards first.

The NASA Exoplanet Archive is unreachable from this environment (egress policy
returns 403 on CONNECT), so exoplanets.json cannot be regenerated here and still
carries no periods. Behaviour is therefore unchanged until `npm run etl` is run
somewhere with archive access, at which point every planet with a published
period starts moving correctly with no further code changes. build.ts reports
how many records gained a period, and rejects non-positive ones.

Tests: 171 passing, up from 151, including a new end-to-end check that
TRAPPIST-1 b with its real period completes exactly one orbit in 1.51088 days
and sits a full diameter away at half that.

Claude 4aca223027 Regenerate the star catalogue, fixing 2331 names and 875 colours
Two ETL bugs, both fixed at the source and then re-run against HYG. Star ids,
ordering and positions are all unchanged, so stars.bin is byte-identical and
every exoplanet cross-reference still resolves.

Names. HYG's `gl` column already carries its own catalogue prefix ("Gl 581",
"GJ 3512"), unlike the bare numbers in `hd` and `hip`, so prefixing it again
produced 2331 of 8750 stars named "Gl GJ 1076". That corrupted three surfaces at
once: search, the on-screen labels, and exoplanet host-star name matching, which
compares normalised names and could never match "glgj1076" to "gj1076".

Colours. `Number(row['ci']) || 0` cannot tell a blank cell from a real zero, and
0 is a real B-V colour index meaning a hot blue-white A-type star. All 875
affected stars turned out to be blanks — the catalogue contains no genuine zero
inside the distance cutoff — so several hundred red dwarfs were rendering
blue-white. colorIndex is now `number | null` rather than defaulted, because any
numeric default is indistinguishable from a measurement.

Consumers resolve the gap from the spectral type instead. That needs real
parsing: HYG's `spect` column runs to 134 distinct spellings among the affected
stars alone, including a bare lowercase "m" for 354 of them, plus "k-m" ranges,
"dM4" luminosity prefixes and "K:" uncertainty flags. 622 of the 875 recover a
class this way — 497 of them M-class — and the remaining 253, which carry no
classification at all, fall back to neutral white.

The parse is anchored at the start of the string rather than scanning it. A scan
is the obvious implementation and is quietly wrong: the ETL writes the literal
"Unknown" for unclassified stars, that contains a K, and every one of those 253
would have been classified as an orange K-type. A test covers it.

Also lifts parseOptionalNumber out of fetchExoplanets into lib/csv, where both
fetchers now use it, and gives magnitude a faint default instead of 0 — no
current star is affected, but 0 would mean "as bright as Vega" and render an
unphotometered star as one of the largest points on the map.

Tests: 145 passing, up from 116, including the first coverage of
StarFieldRenderer. Build, both typechecks and the Playwright suite are green.

Claude 06cf7d2a15 Fix four defects a user hits in the first minute
Found by surveying the codebase against the plan; each was verified against the
committed assets or the running app before being touched.

TRAPPIST-1 was orbiting the Sun. The Exoplanet Archive leaves sy_dist blank for
some systems, and fetchExoplanets.ts read it with bare Number() — Number('') is
0, which is finite, so it slipped past the Number.isFinite guard in
resolveHostStarId, placed the host at the origin, and matched Sol at distance
exactly 0. 127 records shipped with hostStarId 0, all seven TRAPPIST-1 planets
among them, and the system view filters on that id, so drilling into Sol drew
127 alien worlds inside the real solar system.

Fixed in three places: resolveHostStarId now rejects a non-positive distance
(the robust guard, covering every caller), fetchExoplanets.ts uses the
parseOptionalNumber that already sat unused in that same file for ra/dec/dist,
and validateExoplanets asserts nothing ever resolves to the Sun again — the Sun
has no exoplanets, so that tripwire costs nothing and is permanent.

The archive's endpoint is blocked by this environment's egress policy, so the
ETL cannot be re-run here. The committed asset was corrected in place instead,
which is safe because the outcome is deterministic: the name path runs first and
none of the 127 resolve by name, so all of them reached id 0 positionally and
the fixed pipeline yields null for exactly that set. Cross-referenced hosts drop
from 761 to 634; record count is unchanged.

Dragging to rotate selected stars. Selection was bound to the raw click event,
which browsers fire on release however far the pointer travelled and which
OrbitControls does not suppress — so any drag ending over a star launched a
camera flight, and in system view routed away to /body/:id. Now tracks
pointerdown and ignores a release more than 5 px from it.

Ghost systems accumulated on every star-to-star hop. SystemOrbitsRenderer.dispose
released geometries and materials but never detached its group, so old orbit
lines stayed parented forever — still traversed and re-uploaded each frame with
disposed geometries, drawn over the new system and unpickable. dispose() now
detaches and clears.

Galaxy star labels stayed pinned inside the system view. They are CSS2D objects
parented to the scene rather than to galaxyGroup, so hiding the group left up to
15 parsec-space names clumped over the system's star. Cleared on entry. Also
gated the per-frame Kepler propagation on actually being in a system; it ran in
galaxy view too, because the renderer is never nulled on exit.

Tests: 116 passing, up from 112. Build, both typechecks and the Playwright suite
are green.

Claude 3a859360ba Add the deep-sky backdrop, the last unbuilt piece of the plan
The design doc scopes deep-sky objects as a galaxy-view backdrop and lists
fetchDeepSky.ts, deepsky.json and deepsky.model.ts, but none of it existed —
it was the only part of the plan with no implementation behind it.

ETL: fetchDeepSky.ts pulls the OpenNGC catalog, classifies each object as a
galaxy/nebula/cluster, and keeps the ~460 worth drawing (everything Messier,
everything with a common name, and anything brighter than magnitude 9) out of
~12,000 mostly-anonymous rows. build.ts runs it and validates the output.

Distances are the hard part: OpenNGC has no distance column, and both fallbacks
fail for the best-known objects. M31, M33 and M42 are Local Group members whose
redshift is negative or absent, and a galaxy's catalog parallax comes from a
cross-matched foreground star — 6 mas for M31 would put a 780 kpc galaxy at
167 pc. So records store a unit direction on the celestial sphere rather than a
position (the line of sight is always known precisely, and the objects are drawn
on a fixed backdrop shell where true distance is unusable anyway), and distance
is optional metadata carrying its own provenance. Parallax is trusted only for
galactic objects, redshift only above z=0.003 where expansion outweighs peculiar
velocity. 330 of 463 get a distance; the rest honestly report none.

Rendering: DeepSkyRenderer paints the objects as soft additive billboards on a
2500 pc shell — clear of the 50 pc star field, beyond the camera's 2000 pc orbit
limit, and inside its 5000 pc far plane. Size comes from real angular extent, so
Andromeda is six times wider than the full Moon, clamped at both ends. Sprites
rather than points because the WebGPU backend caps point primitives at one pixel;
materials are shared per kind and brightness band, so 460 objects cost nine of
them. The brightest dozen get permanent labels, which needed the label overlay to
accept string ids alongside numeric star ids. The backdrop is decorative, so a
failure to load its dataset is logged and the star field comes up regardless.

Also documents the app in the README, which until now covered only the plugin
marketplace.

Tests: 112 passing, up from 54. Build, both typechecks and the Playwright suite
are green.
