SenrokaiandClaude Opus 5.5 8c3a86097c Place a star at whichever of its two distances is the more precise, not at Gaia's regardless
placementDistancePc took Gaia's distance wherever the cross-match gave a usable one, and its
docstring and c64eea0 called that "the better measurement", adding that Gaia saturates on the
brightest stars "so those sit at their Hipparcos distance". For 273 of the 88 781 HYG stars with
both, Gaia's relative error is the larger, 257 of them naked-eye and 38 by more than twice: Eta Leo
was drawn at Gaia's 556.6 pc ±17 % against Hipparcos's 389 pc ±6.2 %, Schedar and Tarazed at
Gaia's though both have Gaia G of about 2.

placementDistancePc now takes both relative errors and picks the smaller, Gaia's as before when
either is missing; fetchStars gives the placed star the error and the Gaia-distance flag of the
distance it took. The merge's combine keeps the Gaia entry's direction, and now takes the other
entry's distance with its error where that is the more precise, so a bright star Gaia's main query
also holds lands at its Hipparcos distance too. Gaia still wins for the rest, whose parallaxes are
some fifty times more precise.

From cache: 424 stars move, 386 of them naked-eye; HYG rows at Gaia's distance 58 379 -> 58 109 and
HYG stars flagged so 8 129 -> 8 095. Eta Leo 556.6 -> 389.1 pc, Tarazed 178.9 -> 121.1, Imai 139.5 ->
105.8, Schedar 71.0 -> 70.0, Alphecca 23.7 -> 23.0, each now "±" its Hipparcos error. Where the two
disagree by more than 5 σ (21 stars, Iot Gem 11 σ), one of the formal errors is wrong, and this
takes the smaller one at its word. The validators pass unchanged.

Controls, each failing its named test: the placement ignoring the errors, the merge keeping Gaia's
distance whatever the errors, and taking the distance but not its error (1 of 805 each).

SenrokaiandClaude Opus 5.5 23547defe0 Read an archive host's colour off the dwarf sequence at its temperature, and say it was not measured
For an archive-placed host with a temperature and no B magnitude, fetchExoplanets took B−V from
Ballesteros' blackbody fit, which runs 0.1 to 0.2 redder than Pecaut & Mamajek's dwarf sequence
below 3 800 K, and the luminosity then read its correction off that sequence at that colour: 3 500 K
came back as 3 102 K with a correction 1.15 magnitudes too large, anything under about 3 170 K was
clamped to B−V 2.00, and the card printed it as a measured "Colour B−V 2.00". CFBDSIR
J145829+101343, a 580 K brown dwarf, read "Spectral type ~M6, from colour".

temperatureToColorIndex now reads the table itself backwards, interpolating B−V between the two
types the temperature falls between, so the temperature and correction read back off the colour
are the table's at that temperature; it has no answer outside 2 420 to 31 400 K. The colour is
flagged colorFromTemperature, a fifth bit in the photometry byte (the format, README and the ETL's
round-trip check follow), and the card prints it "B−V 1.66, from its temperature", marked derived.

From cache: 57 archive stars change colour; 54 carry the flag and 3, CFBDSIR J145829+101343 among
them, now have none. For the 47 of them the archive gives a luminosity, the one derived from
magnitude and colour moves from a median 0.228 dex off it to 0.124; Kepler-445 (3 157 K) from
0.0282 L☉ to 0.0080 against the archive's 0.0079. Its colour goes from 2.00 to 1.67. The card shows
the archive's luminosity where it has one since earlier on this branch, so this is the figure used
for the rest and for their radii.

Controls, each failing its named test: the nearest hotter row taken without interpolating (2 of
803 failed), no refusal outside the table, the flag not encoded, and the card calling the colour
measured (1 of 803 each).

SenrokaiandClaude Opus 5.5 f82b5e1c74 Hold the published catalogue to what its host radii, distance errors and Gaia-distance flags come to
Three things the branch added could vanish from the data with every check passing, as the review
showed with guarded ETL mutants: dropping st_rad or st_teff from each planet left 0 of 6 354
carrying their host's radius or temperature, storing Gaia's parallax_error in milliarcseconds
rather than over the parallax changed 431 464 distance readouts, and dropping the flag fetchStars
sets relabelled 8 129 HYG stars placed at Gaia's distance "HYG". The round trip compares decoded
with encoded, and the counts of missing bands and errors do not look at what the values are.

validateExoplanets now requires 90 % of planets to carry their host's radius and temperature
(measured 6 030 and 6 054 of 6 354). validateStars requires the median relative error of the
distances at Gaia's to be under 1 % (measured 0.33 %), at most 1 % of stars to have a parallax
distance with an error of a fifth or more (measured 1 109, 0.24 %; the archive's, which are on the
distance and never ranged, are left out), and at least 6 000 HYG stars flagged at Gaia's distance
(measured 8 129). Figures from an ETL run from cache on this branch.

Each proved by a guarded mutant in a scratch copy of the ETL, run from the cache, failing with its
own message: host radius dropped ("Only 0 of 6354 exoplanets carry their host's radius and 6054 its
temperature"), host temperature dropped ("6030 ... and 0"), the Gaia error left in mas ("The median
error of Gaia's distances is 1.92 %"), the same with the median check waived ("17689 parallax
distances have an error of a fifth or more"), and the flag dropped ("Only 0 HYG stars are flagged
at Gaia's distance"); a no-op edit completed. No ceiling is loosened.

SenrokaiandClaude Opus 5.5 6d81c45f45 Carry the archive's positions back from Gaia DR2's J2015.5, where it publishes them, not J2016
fetchExoplanets placed each star it adds from the Exoplanet Archive by carrying the archive's
position back sixteen years, and 4c8e4a0 said the archive publishes at Gaia's J2016. It does not:
its positions are Gaia DR2's at J2015.5 although it names the DR3 source. Barnard's star in the
archive, 269.4486144, 4.7379808, equals DR2 4472832130942575872 at J2015.5 to 1e-7°, and sits 5.2″
from DR3's J2016 place; the review found 66 of the 67 archive-placed stars moving over 100 mas a
year within 0.21 mas of their DR2 position and none within 1 mas of DR3's. The matcher's comment
made the same claim of HD 133131 and TOI-2459, whose positions are DR2's too.

host-star-matching.ts now exports CATALOGUE_EPOCH and ARCHIVE_EPOCH = 2015.5, the matcher carries a
query back by their difference, and fetchExoplanets uses the same two, so the epoch is written
once. From cache: only the 3 277 archive-placed stars move, 2 287 of them by more than a
milliarcsecond, 74 by more than 50 and TOI-2406 most, by 203 mas, half a year of its 405 mas/yr;
no planet changes host. Invisible at map scale; the point is that the constant and its comments
now say what the archive does.

Control: ARCHIVE_EPOCH back to 2016.0 fails "carries Barnard's star from the archive's position to
where Gaia DR3's goes, to a few milliarcseconds" (1 of 802), which puts the two 5.2″ apart. The
GJ 15 A matching fixture is now built at J2015.5 too. fetchExoplanets' use of the constant has no
test of its own; the ETL has no test harness.

SenrokaiandClaude Opus 5.5 62f81f2c43 Number the stars the archive places after their host's name, so a refresh keeps each one's id
4c8e4a0 numbered each star it adds from the Exoplanet Archive by its place among the unmatched
hosts, in pl_name order, and the refresh workflow re-queries the archive every Monday. One host
added or dropped ahead of another renumbers it: in the review, removing a single planet row
renamed 3 276 of the 3 277 ids, and a bookmark kept on Kepler-186 (1070001620) opened Kepler-1860
under Kepler-186's stored name. HYG's and Gaia's ids do not move between refreshes; the merge's own
comment says ids are meant to hold.

archiveStarId (host-star-matching.ts, beside the matcher the ETL already imports from there) hashes
the host name with FNV-1a into the 3.7 million ids between 1 070 000 000 and 2^30, and moves a name
whose id is taken to the next free one. The added stars are sorted by id before they are appended,
so the published list stays in id order. Measured: all 4 237 archive-hosted planets change host id
once (Kepler-186 is now 1073671518), none of the others; one of the 3 277 names was probed past a
collision, and one new id falls in the old 1070000000-1070003276 range, so a bookmark saved on that
old id would open the wrong star once. Dropping the same row from a copy of the cached answer and
rerunning the exoplanet step in a scratch copy of the ETL now leaves 3 276 of 3 276 ids unchanged.
The validators pass: no duplicate id, all under 2^30.

Controls, each failing its named test: the id taken from the order of arrival, and no probing past
a taken id (1 of 801 each).

SenrokaiandClaude Opus 5.5 1a8e734651 Leave the dark nebulae out of the backdrop, whose sprites can only add light
c01d3ec read OpenNGC's addendum, which brought in its only two DrkN rows, C099 the Coalsack and
B033 the Horsehead; NGC.csv has none. classifyOpenNgcType mapped DrkN to 'nebula', so both were
drawn as the backdrop's nebula sprite: ff86b0, additive, at the faintest opacity and the 70 pc
minimum size, about 1.6° across. The review measured it adding up to +59 in red over the Coalsack
beside Crux, where the sky has a dark hole, and darkening no pixel, as an additive sprite cannot.

DrkN is now among the codes dropped, with the reason beside the map. fetchDeepSky from cache keeps
488 objects against 490, still 107 Messier objects and every required id; README's count follows.
On :4302 the served backdrop holds 488 objects and the scene 488 sprites, neither of them C099 or
B033.

Control: DrkN mapped back to 'nebula' fails "leaves out a dark nebula, which a sprite that adds
light cannot draw" (1 of 801).

SenrokaiandClaude Opus 5.5 0e9ab6ffb5 Fold the Gliese entries that move with a Gaia star up to 160″ away, where a minute left 39 twice
74b93a0 let a Gliese-only HYG row fold into a Gaia entry that moves with it up to a minute of arc
away, since Gliese's positions are off by that much. Its report counted only the 3-60″ residue.
Measured on the published catalogue with the merge's own motion and brightness rules, 39 Gliese
rows within 25 pc still had a bare Gaia entry moving with them 60 to 150″ away (32 within 100″,
none past 150); with every row shifted a quarter of a degree north or south, none did. The review
found 36 of them to be the same star under SIMBAD, three within 10 pc: GJ 3618 (LHS 288) at 4.49 pc
beside its Gaia entry at 4.83 pc 94″ away, GJ 1123 at 8.13 and 9.52, GJ 1001 at 9.60 and 12.31.

MERGE_COMOVING_ANGULAR_TOLERANCE_DEG is now 160″. The ETL from cache folds 62 046 entries against
62 002, leaves 11 510 HYG rows without a counterpart against 11 554, and publishes 455 564 stars;
within 10, 25 and 50 pc the map now holds 369, 5 523 and 40 877 against 372, 5 564 and 40 921
(GCNS: 312 Gaia sources within 10 pc). No Gliese row within 25 pc has a co-moving bare Gaia entry
3-300″ away any more. GJ 3618, GJ 1123, Gl 319C and GJ 3999A now sit on Gaia entries. One
exoplanet changes host id: LHS 475 b's Gaia entry took HYG's id with its description.

Not every name lands where SIMBAD would put it: Gl 319C takes the entry SIMBAD calls GJ 319 B, as
HYG's Gl 319B already sat on SIMBAD's C, and GJ 3999A takes the entry named GJ 4000B before, which
moves to the bare one beside it. Both systems go from one entry too many to one per star; the
names follow HYG's positions, which only identifiers could correct. The merge validators hold: 23
cross-catalogue pairs within an arcsecond, as before.

Controls, each failing its named test: the window back to a minute (2 of 801 failed), and 200″
(1 of 801).

SenrokaiandClaude Opus 5.5 150ec76bbd Say that a host's radius, temperature and luminosity come from the composite table alone
The comment on hostStarRadiusSolar and its two neighbours said they were read from "the planet's
default row first, then the composite table". The default-row query (TAP_COLUMNS in
fetchExoplanets.ts) asks for none of st_rad, st_teff or st_lum — the cached answer's columns end at
st_mass and disc_year — so host() always reads them from pscomppars, whose columns may each cite a
different reference: Proxima's 0.141 R☉ is the composite table's. It also said they were measured
where stellar.ts derives a luminosity, which held for the luminosity only once starSurfaceOf began
reading st_lum, earlier on this branch; it now points at starSurfaceOf. A comment, so there is no
test to fail.

SenrokaiandClaude Opus 5.5 4ebe663a84 Carry the Hipparcos parallax errors between weekly refreshes, as the Gaia answers already are
a81dd49 added a query of public.hipparcos_newreduction on the ESA archive, cached as
hipparcos-errors-<hash>.csv, and fetchStars requires it: a failed or short answer throws. The
refresh workflow carries only tools/etl/.cache/gaia-dr3-*.csv between runs, a glob that file does
not match, so every weekly run fetched its 117 955 rows live from the archive the cache exists to
spare, and an ESA outage would have failed the refresh even with every Gaia answer cached. Before
a81dd49 a warm cache meant no request to that archive at all.

The cache step now lists both globs. Its key gains "-hipparcos": actions/cache keys are immutable,
and an entry already saved under the old key would be restored without the new file and never
saved again. Checked with Node's path.matchesGlob against the local cache (gaia-dr3-54fdbc7a,
gaia-dr3-hip-785b92fc and hipparcos-errors-f846b045 match, the archive's own files do not) and by
parsing the workflow with PyYAML. A workflow file has no unit test to fail without the change.

SenrokaiandClaude Opus 5.5 08bf8b18a6 Test that a Gaia star with no measured band is still labelled Gaia's
describingCatalogue calls a star Gaia's when its source is gaia and its band is not V. 44 Gaia
sources in the shipped catalogue have no G (Gaia DR3 40091256260676736 among them), and nothing
tested them: narrowing the rule to band G, which would relabel all 44 "HYG" and count them as HYG
in the neighbourhood census, passed the suite. The existing test already builds such a star and
now checks its Source row as well.

Control: the rule narrowed to band G fails "says a stand-in magnitude was not measured, and leaves
out a colour there is none of" (1 of 797).

SenrokaiandClaude Opus 5.5 f8af0ecf6e List stars in search and routes by the type their colour gives them, and say where archive positions come from
5333be6 gave the star card an estimated type for the 383 695 stars the ETL files as "Unknown",
but search rows, the route search index and the current-star route option still printed that
literal: TRAPPIST-1 read "STAR · UNKNOWN" in search beside "Spectral type ~M8, from colour" on its
card, audit #17's own symptom. spectralClassification (spectral.ts) now gives the catalogue's type,
else the colour's marked "~", else nothing, and all three and the card's subtitle use it; a search
row with nothing to add prints its kind alone rather than a trailing " · ".

The neighbourhood note still read "Positions from measured parallaxes" after 4c8e4a0 placed 3 277
stars at the Exoplanet Archive's sy_dist, 343 of them without a usable parallax and 281 of those
past 1 kpc — microlensing hosts such as OGLE-2005-BLG-390L at 6.6 kpc, from a lensing model.
positionsNote now says so, with the count. Neither the note nor the census subtitle (audit #16) had
a test: putting back "Hipparcos · Yale Bright Star · Gliese" passed all 775.

In the app on :4302: the note reads "Positions from measured parallaxes, and for the 3,277 planet
hosts only the NASA Exoplanet Archive places, from its distances. Grid marks the galactic plane
through the Sun."; search reads "TRAPPIST-1 STAR · ~M8", "OGLE-2005-BLG-390L STAR", "Sirius STAR ·
A0M"; TRAPPIST-1's route option has subtitle "~M8".

The scene spec gains an archive-placed fixture star. Controls, each failing its named test: the
search row printing the raw type, keeping the separator with nothing after it, the route index
and the current-star option printing the raw type, the note back to parallaxes only, the subtitle
back to the old catalogue list (1 of 797 each), the note never counting the archive (2 of 797),
and the classification without its estimate (3 of 797).

SenrokaiandClaude Opus 5.5 4191b70e63 Tint a star measured in Gaia's BP−RP as the B−V of the dwarf of that colour
colorIndexToRgb maps a B−V onto the star field's tint ramp, and its one caller passed it every
star's colour index, whatever colorSystem said. BP−RP is the larger of the two for the same star —
0.823 against 0.65 for a G2 dwarf, 1.84 against 1.42 for an M0 (Pecaut & Mamajek) — so the 376 703
stars measured in it, 83 % of the catalogue, were tinted as later types than they are, and redder
than HYG's stars of the same type, and than their own disc in the system view.

A BP−RP is now carried to the B−V of the dwarf sequence at that colour (the table's own B−V
column, which DwarfSequencePoint now returns, clamped at its ends), then tinted as before. The
median Gaia colour, BP−RP 0.883, a G7 dwarf, read as a K2: its tint goes from (1, 0.972, 0.955) to
(0.975, 0.982, 1), the same as HYG's G7 stars.

Controls, each failing its named test: BP−RP read as B−V (2 of 792 failed), the star field not
passing the colour system (1 of 792), and the B−V taken from the wrong column (3 of 792).

SenrokaiandClaude Opus 5.5 fa52f6a818 Give an archive star's distance error as the error on the distance it is, not as a parallax range
formatDistance printed any error of a fifth or more as the range a parallax's error makes,
d/(1+e) to d/(1−e). A star the ETL places from the Exoplanet Archive carries the mean of sy_disterr1
and 2 instead, which the archive defines as one-sided errors on sy_dist in parsecs, and many of
those distances come from a lensing model with no parallax behind them. 129 of the 3 195 archive
stars with an error were printed as ranges the archive does not give: KMT-2016-BLG-1836L as 5.8 to
9.2 kpc, where the archive publishes 7 100 +800 −2 400 pc, and AT2021ueyL as 664 pc to 2.4 kpc
against 1 040 +740 −440.

The card now tells formatDistance when the error is on the distance (source exoplanet-archive), and
it keeps the ± at any size. Measured on the shipped catalogue: KMT-2016-BLG-1836L reads 7.1 ± 1.6 kpc,
AT2021ueyL 1.0 ± 0.6 kpc, EPIC 201170410 134 ± 43 pc, KMT-2016-BLG-0212L 6.3 ± 1.3 kpc. The ETL keeps
only the mean, so a lopsided interval such as KMT-2016-BLG-1836L's is shown symmetric; carrying both
errors would take a second column in stars-meta.bin. The doc comments on formatDistance and on
distanceError no longer say an archive distance is an inverted parallax.

Controls, each failing its named test: the error on the distance read as a parallax's (2 of 790
failed), and the card not saying it is on the distance (1 of 790).

SenrokaiandClaude Opus 5.5 d1aa22ed61 Frame a giant so its disc sits inside the ring its neighbours are named on
The system view names a star's neighbours on a ring at 0.74 of the view's tighter half-extent,
whatever the star. A giant was framed to fill the frame, 2.4 radii out, which the three-radius
closest approach then overrode, so it settled at 3 radii with its disc projecting to 0.758 of the
half-extent: in the app, Betelgeuse's disc was 379 px on a 1 000 px view against the 370 px ring,
and HD 39374 and HD 38118 were printed on it at about 1.3:1 contrast.

The star's term in the framing distance now places its silhouette, asin(R / d), at half the
tighter half-extent, which puts the camera 4.4 radii out on a 50° view. Measured on :4302 at
1600 by 1000: Betelgeuse settles at 13.9 AU (closest approach 9.5) with a 250 px disc and Antares at
14.1 AU; the nearest corner of any neighbour's name is 292 px from the centre, so none is on
either disc (it was two and one of them before). Closing in to the closest approach can still bring
the disc over the names; that is the viewer's choice, not the arrival's.

This also gives the star's term a job: at 2.4 radii it never exceeded the closest approach, so
dropping it changed nothing (the previous commit's one surviving control). Controls, each failing
its named test: the star left out of the framing (1 of 788 failed), the star framed to fill the
frame (2 of 788), and the disc taken as flat (1 of 788).

SenrokaiandClaude Opus 5.5 5aac46de08 Draw a star nothing gives a size or temperature for as a grey point, not as the Sun
The system view drew every star without a radius at the Sun's radius, and every star without a
temperature in the Sun's colour. PSR J1719-1438, a neutron star 10 km across, came out 1 R☉ wide,
wider than its planet's 0.0044 AU orbit, and b spent nine tenths of its orbit inside it; Procyon B,
a white dwarf of 0.012 R☉ with a type the parser does not read and no colour, was a Sun 81 times
too wide in the Sun's colour.

Such a star is now drawn at 150 km, under the three-pixel floor from anywhere the camera can go, so
the floor's point is what shows, and its disc keeps the photograph's own grey instead of the Sun's
tint. Its light stays white, which is the photographs' own light rather than a claim about the
star. 2 858 stars take this after the clamping in the previous commit, against 3 077 drawn at the
Sun's radius before it.

In the app on :4302: PSR J1719-1438's star is drawn at 1.7×10⁻⁴ AU (the floor, 168 times its
geometry) with b 0.00417 AU from its centre, outside it; Gl 280B at the floor, tint (1, 1, 1) and no
radius on its card; Proxima at 0.141 R☉, tint (1, 0.459, 0.135), light (1, 0.523, 0.165), card
"Luminosity 0.002 L☉" unmarked and "Radius 0.141 solar radii".

The scene's use of the star's surface had no test: every star in the scene spec was drawn at the
Sun's radius, and drawing all of them so, lighting planets white, tinting every disc as the Sun or
closing the camera to the Sun's clearance all passed. The spec now gives Proxima its planet's
archive row and adds Antares and Procyon B, and three tests enter them. Controls, each failing its
named test: every star at the Sun's radius (3 of 787 failed), an unmeasured one at it, the light
without the temperature, the closest approach for the Sun, the Sun's tint for a host, the Sun's tint
for a star without a temperature, and the card without the surface (1 of 787 each). Dropping the
star from the framing distance was not caught: its term, 2.4 radii, never exceeds the three-radius
closest approach the camera is clamped to, so it cannot change where the camera settles.

SenrokaiandClaude Opus 5.5 31e0c04fe1 Read a colour past either end of the dwarf table at that end, where the star has no type instead
dwarfSequenceAtColor answers null outside Pecaut & Mamajek's table, B−V −0.301 to 2.16 and BP−RP
−0.12 to 5.1, and effectiveTemperatureK then fell back on the type, which Gaia's stars do not have
and carbon stars' parser does not read. 219 stars with a measured colour got no temperature and so
no radius, and were drawn at the Sun's radius in the Sun's colour: 110 white dwarfs within 50 pc,
38 Gaia stars redder than BP−RP 5.1 (Gaia DR3 6439125097427143808, an ultracool dwarf 4.0 pc away),
HD 46687, La Superba and the other carbon stars, and an O8 star.

Past the table, the colour is now read at the row it is past (clampToTable), but only for a star
with no readable type: beside a type an off-table colour is more often the bad measurement — HD
49748 is G5 V at B−V −0.32 — so the type still wins there, as it did. The luminosity reads the same
point, so a star past the red end also gets the M8.5 row's G−V and correction. A type's own colour
past the table, which only O types have, is read at B0. Carbon and S stars (C, N, R, S) now count
as giants, so their correction stays their type's, not an M8.5 dwarf's −5.78.

Measured on the shipped catalogue: stars without a temperature 3 053 -> 2 834, without a radius
3 077 -> 2 858; all 292 stars with an off-table colour now have a temperature, against 73. Gaia DR3
6439125097427143808 is 2 420 K and 0.110 R☉ (M8.5 V: 0.104); the 110 white dwarfs a median 0.018 R☉
at 10 700 K (0.0013 to 0.034); HD 46687 212 R☉ at 2 420 K and La Superba 133; audit #16's Gaia DR3
5612323414549657984, k1 Pup, B6 V at BP−RP −0.15, 203 L☉ and 4.1 R☉ against 143 and none (FLAME
gives 336 and 3.49). The 2 851 stars left without a radius have neither a colour nor a readable
type, or no band.

Controls, each failing its named test: no clamp for an untyped star (2 of 784 failed), the clamp
winning over a type, an O type's colour unclamped, the luminosity off the unclamped sequence, and
carbon stars not counted as giants (1 of 784 each); clampToTable ignored (3 of 784).

SenrokaiandClaude Opus 5.5 d097f4b477 Correct a giant's light by its type, not by the cooler dwarf its colour reads as
3392f06 read every star's bolometric correction off the dwarf sequence at its colour, so a giant
got the correction of the cooler dwarf of that colour, which is larger. Antares, M1 Ib at B−V 1.87,
took an M5 dwarf's −3.26 and came out 172 023 L☉ and 1 516 R☉, a 7.06 AU sphere, against the 680 R☉
Ohnaka et al. (2013) measure; 119 Tau 2 838 against 587, Menkar 204 against 89.

isGiant (spectral.ts) reads luminosity class I to III off a type's primary component, or HYG's g
and c prefixes, and a giant keeps its type's correction. Drawn radius against the published one
(no planets, so derived), before and after: Antares 2.23 -> 1.01, 119 Tau 4.84 -> 1.43, Menkar 2.29
-> 1.80, Scheat 1.92 -> 1.42, Aldebaran 1.95 -> 1.10, Mirach 1.96 -> 1.27, 41 Com 2.14 -> 1.56;
Betelgeuse 0.76 -> 0.89. It is not better everywhere: Gacrux goes from 1.23 to 1.40 and Arcturus
from 1.02 to 0.88. 10 808 stars have a giant's type, 10 794 of them a colour. Against the archive's
own luminosity for the 130 giant hosts, the median error moves from 0.038 to 0.052 dex and the 90th
percentile from 0.246 to 0.204; 17 are off by over 1.5 times, against 19.

Controls, each failing its named test (1 of 781): the giant given the dwarf's correction, a giant
companion read as the primary, a IV read as a I, and the prefixes ignored.

SenrokaiandClaude Opus 5.5 d94451e203 Warm a host's planets by the luminosity the archive publishes for it, not one derived beside it
The ETL has carried each host's st_lum since 494fb56 and nothing read it: the card, the system
view's planet temperatures and the body pages all derived a luminosity from the star's magnitude
and colour. For 757 of the 4 440 hosts the archive gives one for, the two differ by more than
1.5 times, 667 of them stars the ETL placed from the archive's own V and B−V. Proxima read
8.9×10⁻⁴ L☉ beside the archive's radius and temperature, which imply 1.27×10⁻³; the archive gives
1.51×10⁻³, as Ribas et al. 2017 do.

starSurfaceOf now returns the luminosity with the radius and temperature, taken from the first of
the host's planets that gives one, as st_rad and st_teff already are, and derived only otherwise.
The system view lights its planets with it, the body page uses the same host rule, and the card
marks it derived only when it is. The derived radius still comes from the derived luminosity, so
its "from colour and brightness" stays true; only 3 hosts have st_lum and no st_rad.

Measured on the shipped catalogue against the parent commit: 544 of 3 639 planets with an
equilibrium temperature move by more than 10 %, and 98 change class. Kepler-186 f goes from a 292 K
rocky world to a 175 K icy one, LHS 1140 b from 152 K icy to 206 K temperate, LTT 1445 A b from
298 K rocky to 402 K scorched, Proxima Cen b from 200 to 228 K and d from 259 to 296 K.

starReadouts now takes the surface alone, which carries the luminosity. Controls, each failing its
named test: the archive's luminosity ignored (2 of 778 failed), called derived, the body page
warmed by the derived one, the body page reading the planet's own row only, and the card marking
a published luminosity derived (1 of 778 each).

SenrokaiandClaude Opus 5.5 869635bec1 Give a star no survey measured no luminosity, so its planets get no temperature from a stand-in
luminosityOf derived a luminosity from any magnitude, including the stand-in the ETL writes for
the 309 stars with neither a V nor a G. starSurfaceOf already refused it for the radius; the card,
the system view's planet appearances and the body pages did not. The 265 archive hosts among them
came out at a median 33 L☉: KMT-2016-BLG-1107L, a 0.087 M☉ star, at 36.8, and OGLE-2005-BLG-390L b,
published at about 50 K, read 388 K and a sub-Neptune. Their cards printed "Magnitude: Not
measured" beside a luminosity derived from that magnitude.

The guard now sits in luminosityOf, which every caller goes through, so the one in starSurfaceOf
is gone. The Sun keeps its 1 whatever band it is filed under. Measured on the shipped catalogue:
of the 275 planets on those 265 hosts, 268 had an equilibrium temperature and 0 now do; before
the archive stars were added they had no host, and so none either.

Controls: without the guard, "has none from a magnitude no survey measured, and gives its planets
no temperature from it" fails (with the radius test beside it, 2 of 777); without the Sun's
exemption, "is 1 for the Sun, whatever its magnitude is filed under" fails (1 of 777).

SenrokaiandClaude Opus 5.5 2242fe0a7f Give every star a limb-darkened surface in its own colour, and light its planets with it
Every star but the Sun was a flat disc of one colour, and the Sun wore the texture pack's orange
photograph, lit by the same white light as every other star's planets.

Every star now shares one TSL material (starSurfaceMaterial in the scene): the Sun's map in grey,
times the colour of a blackbody at the star's temperature, times a linear limb-darkening law,
1 - 0.6 (1 - mu), the Sun's coefficient in the visible. The temperature is the one the radius
uses: the archive's st_teff for a host, else the dwarf sequence at its colour or type, else
the Sun's.
The colour comes from blackbodyColor (stellar.ts): Kim et al.'s cubic fit to the Planckian locus,
then CIE XYZ to linear sRGB, brightest channel 1. At D65 it gives 2 900 K (255, 180, 103), 5 800 K
(255, 241, 235) and 9 600 K (208, 219, 255), against (255, 182, 98), (255, 241, 231) and
(211, 221, 255) in Charity's integrated blackbody table. The tint is a uniform, so the shader is
built once and not per system.

The star's PointLight takes the same colour against the Sun's, since the planets' photographs
were taken in sunlight: the Sun's light stays white at pi, TRAPPIST-1's (2 566 K) is
(1, 0.44, 0.10) and Proxima's (2 900 K) (1, 0.52, 0.17), Sirius's (0.52, 0.67, 1). The intensity
stays pi. No halo comes back.

sun.jpg was 2048 by 1024 and 822 427 bytes for a disc that reaches 216 px across at the Sun's
closest approach on a 1080-line screen. It is now 1024 by 512 in grey, 31 306 bytes, which covers
the disc to a 1440-line screen. Its brightness varied by 56 % rms, which made every star a mottled
rock; it is rescaled to 14 % rms about the display's white, of the order of the Sun's granulation
contrast, the brighter half clipped as in a photograph exposed for the disc (6 % rms remains).

Measured on the dev server (1600 by 1000, the camera at its closest approach):
- the disc's brightness against the law, from r/R 0.52 to 0.97: Sun 0.970/0.841/0.763/0.657/0.560
  against 0.927/0.829/0.755/0.645/0.554, ups And and Sirius the same to within 0.05;
- the disc's centre in sRGB: Sun (245, 233, 226), ups And (F8V, 6 157 K) (249, 239, 239),
  Sirius (199, 209, 243);
- the first system entry of a fresh page, three runs each in alternating blocks against the
  previous commit: Sol's longest task 90 ms before, 86 ms after, two tasks over 50 ms in every
  run either way; Proxima Centauri's none over 50 ms after, one run of six with a 53 ms task
  before. The long tasks on Sol's first entry predate this change.

SenrokaiandClaude Opus 5.5 7213f987c4 Draw every star at its own radius, measured where the archive has one and derived otherwise
The system view drew the Sun at its own radius and every other star at 0.45 of its innermost
orbit, capped at 0.2 AU: a size chosen so the star would not swallow its planets, not the star's.
Proxima Centauri was drawn at 2.8 solar radii, eighteen times its own, and every star without
planets at 43.

starSurfaceOf (body-view-model.ts) now gives each star a radius and a temperature. A planet host
takes the archive's st_rad and st_teff from its planets' rows: 4 439 hosts are drawn at a
measured radius, 22 at a derived one. Every other star's is derived: its temperature off Pecaut & Mamajek's dwarf
sequence at its colour (the same table the spectral estimate reads, or at the colour its type
implies where it has none), its luminosity from its absolute magnitude and the bolometric
correction luminositySolar already applies, and R = sqrt(L) / (T / 5772 K)^2. Against the
archive's own st_rad for the 1 447 catalogue hosts that have one, the derived radius is within
0.018 dex at the median, 0.071 dex at the 90th percentile, and within a factor of 1.5 for
97.1 %. Sirius comes out 1.79 solar radii (1.711 published, Liebert et al. 2005), Wolf 359 0.117,
Betelgeuse 584, the Sun exactly 1.

A star with no band has only the ETL's stand-in magnitude, and gets no derived radius: PSR
J1719-1438 came out 2.3 solar radii from it, wider than its planet's orbit. With the stars that
have neither a colour nor a type, that leaves 3 077 of 455 608 stars (274 of 4 735 hosts) with
no radius; they are drawn at the Sun's, and their card gives none.

The card says which it is: "Radius 0.141 solar radii" for a published one, "~0.10 solar radii,
from colour and brightness" for a derived one, two figures because colour does not give three.

A giant drawn at its size can be wider than its system, so systemFramingDistanceAu also makes
room for the star, and the controls' closest approach is now three of the star's radii where
that is more than the old 0.05 AU. 23 211 stars are drawn wider than 3.6 solar radii, which put
0.05 AU inside three of their radii, and a zoom would have carried the camera through the
surface of the largest. The Sun keeps 0.05 AU. starMarkerRadiusAu and the renderer's innermost
axis, which only it read, are gone.

SenrokaiandClaude Opus 5.5 3392f06c85 Read a star's bolometric correction off its colour, and carry Gaia's G to V first
A star's luminosity was its absolute magnitude plus a bolometric correction read off its spectral
type, with its magnitude taken as V whatever band it was in. Gaia classifies none of its stars, so
all of its 379 000 got the Sun's correction, and their G was read as V: TRAPPIST-1 came out at a
seventh of its luminosity.

The dwarf sequence spectral.ts already reads types off (Pecaut & Mamajek 2013, table 5, online
version 2022.04.16) now carries its effective temperature, bolometric correction to V and Gaia
G-V columns, and dwarfSequenceAtColor interpolates them at a colour, in the colour's own system.
luminositySolar uses it wherever the star's colour is inside the table: the G magnitude is
carried to V, then corrected. Only without such a colour does it fall back to the spectral type,
as before.

Against the archive's own st_lum for the 1 449 hosts that are catalogue stars, the median error
goes from 0.038 to 0.022 dex and the 90th percentile from 0.292 to 0.115 dex; within a factor of
1.5, 84.5 % -> 93.8 %. For the 572 hosts Gaia describes: 90th percentile 0.332 -> 0.073 dex,
81.8 % -> 97.0 % within a factor of 1.5. Barnard's Star with no type now reads 0.0029 L_sun
against 0.0035 published, and TRAPPIST-1 7.3e-4 against 5.5e-4 (Agol et al. 2021).

Across the catalogue, 311 255 of 455 608 stars move by more than 10 % (median ratio 0.90: a
G-type star's G is 0.16 brighter than its V), and so do the hosts of 3 158 planets, whose
equilibrium temperatures follow as the fourth root.

SenrokaiandClaude Opus 5.5 b46c840369 Warm every body by the microwave background too, so none reads colder than space
The derived equilibrium temperature balanced starlight alone. For the widest orbits that is less
than the 2.7 K every body in space is held at by the cosmic microwave background. The planet 7 493
AU from 2MASS J21252752-8138278 read "Equilibrium temp. 1 K", and the one 19 000 AU out from UCAC4
328-061594 would have read 0 K.

equilibriumTemperatureK now adds the background as a second source in the same balance, T^4 =
T_star^4 + (2.7255 K)^4 (Fixsen 2009). Inside a few hundred AU of any star it changes nothing that
shows: Earth, Mars, Jupiter and Neptune reproduce their published values as before. Across the
6 354 exoplanets, the rounded temperature changes for 11, all on orbits of 350 AU or more. Ten go
from 0, 1 or 2 K to 3 K, from VHS J125601.92-125723.9 b at 350 AU to UCAC4 328-061594 b at 19 000
AU, and 2MASS J22501512+2325342 b at 518 AU goes from 4 to 5 K. On the dev server, the detail
pages of the 7 493 AU planet and of GJ 900 b read "Equilibrium temp. 3 K".

SenrokaiandClaude Opus 5.5 1e3ac57229 Wrap a body's name on its card instead of cutting off the digits that tell it apart
The detail page and the system view's object card truncated the name and the line under it with
an ellipsis. For a designation, the part that went is the part that identifies it: the audit
measured "2MASS J21252752-8138278 b" at 288 px in a 256 px heading, shown as
"2MASS J21252752-81382…", and the eyebrow at 273 px, shown as "EXOPLANET · 2MASS J21252752-8138…".

Both lines now wrap (wrap-break-word) in both places. On the dev server the heading for that
planet is two lines, 45 px high, with its scroll width equal to its 256 px box, and the eyebrow
fits in 256 px.

SenrokaiandClaude Opus 5.5 70cbdae306 Drop the "..." Hipparcos leaves on a spectral type, which read as the app cutting it short
2 127 stars, Sirius among them, read "Spectral type A0m...", in search rows, route options and
the star card. The mark is Hipparcos's own: every one of the 3 803 HYG rows ending in it has a HIP
number, and the catalogue ends a classification it does not print in full with it. The app
truncated nothing, but the text reads as if it had.

fetchStars now trims a trailing "..." from HYG's spectral types. The dictionary in
stars-index.json goes from 3 056 distinct types to 2 883, and from 598 dotted ones to none. The
names, sources and source indices are unchanged, and so is every other column of stars-meta.bin
bar the type indices. gzip -9 of the index goes from 4 015 865 to 4 015 205 bytes.

build.ts validateStars now fails a catalogue with any type ending in "...". Run with the trim
removed, the ETL failed on 2 127 such types. Two ETL runs from cache wrote identical
stars-meta.bin and stars-index.json.

SenrokaiandClaude Opus 5.5 5333be615e Estimate a spectral type from each star's colour where no catalogue gives one, and say so
383 695 of the 455 608 stars read "Spectral type Unknown", every Gaia star among them, although
380 884 of them carry a colour. The card now gives those the type of the dwarf whose colour is
nearest, in the colour's own system, marked as an estimate: TRAPPIST-1, BP-RP 4.90, reads
"Spectral type ~M8, from colour", which is how it was classified (M8 V). A star with neither a
type nor a colour gets no subtitle rather than the literal "Unknown".

The colours are Pecaut & Mamajek's mean dwarf sequence (2013, ApJS 208, 9, table 5), as Mamajek
maintains it online (version 2022.04.16, which carries Gaia BP-RP), from B0 to M8.5. B-V cannot
tell O types apart (the whole sequence spans 0.03 of it), and BP-RP turns back past M8.5 and is
tabulated only from B9. A colour outside the table gets no estimate: 186 BP-RP and 41 B-V colours,
among them the blue Gaia DR3 5612323414549657984 at BP-RP -0.15.

380 657 stars get an estimate: F 97 840, G 144 327, K 105 984, M 29 142, A 3 272, B 92. Checked
against catalogued types:
- 19 433 HYG dwarfs with a B-V: 74.3 % within two subclasses, 95.5 % within five.
- 146 Gaia exoplanet hosts the archive types as dwarfs, from BP-RP: 88.4 % within two
  subclasses, 98.6 % within five.
The estimate assumes a dwarf, so a giant reads later than it is (Pollux, K0 III at B-V 0.99,
reads K3). It also ignores reddening. The comment says both.

SenrokaiandClaude Opus 5.5 a81dd491ad Say which band each star was measured in, whose catalogue it is, and how sure its distance is
The readout named Hipparcos, Yale and Gliese while 378 775 of the 455 608 stars are described by
Gaia DR3, printed one "Magnitude" for G and V alike, and gave every distance to the parsec. The
band cannot be read off the star's source, which records whose position it has: 62 002 stars Gaia
places keep HYG's V and B-V, and the 575 hosts renamed after their planets are Gaia's, in G.

stars-meta.bin gains two byte columns, 14 to 16 bytes a star (6 378 512 to 7 289 728 bytes; gzip
-9 2 804 049 to 3 110 991). One holds the magnitude's band (V 76 555 stars, G 378 744, none 309,
whose magnitude is a stand-in), which colour the colour index is (B-V 75 203, BP-RP 376 703), and
whether the distance is Gaia's parallax. The other holds the distance's relative error as its
square root in 255ths: a step is 0.08 % of distance at 1 %, 0.35 % at 20 %, and 100 % is the top.
encode, decode, BYTES_PER_STAR_META and the build.ts round trip cover both; no workflow reads the
format.

Where the errors come from:
- Gaia rows keep the parallax_error their query already fetched: median 0.3 %, 90th percentile
  1.2 %, at most 20 %, the query's own cut.
- A HYG star at Gaia's distance takes the cross-match's parallax_over_error, and a star merged
  into a Gaia entry keeps that entry's error with its position.
- The 3 067 Hipparcos stars that keep their Hipparcos distance, Rigel, Deneb and Alnilam among
  them, take e_plx from van Leeuwen's 2007 reduction: a new cached query of
  public.hipparcos_newreduction on the ESA archive, whose 117 955 rows HYG's distances invert.
- The archive's stars take sy_disterr1/2 from pscomppars, in a query and cache file of their own
  so the composite rows already cached were not refetched.
- 439 distances have no published error: 357 Gliese rows and 82 archive hosts.

Of the errors, 392 786 are 1 % or less and are not printed; 61 156 print as "117 ± 12 pc" to the
distance's own digits; 1 196 between 20 and 100 %, and 30 past it, print as the range the
parallax gives, since a symmetric error in parallax is a lopsided one in distance.

The star card (measured on the dev server) now reads, for example:
- Rigel: 265 ± 23 pc, V 0.18, B-V -0.03, source HYG.
- Deneb: 433 ± 60 pc.
- Alnilam: "476 pc to 833 pc" (Hipparcos 1.65 ± 0.45 mas).
- Gaia DR3 5612323414549657984: 111 ± 2 pc, G 4.63, BP-RP -0.15, source Gaia DR3.
- Proxima Centauri: 1.30 pc, V 11.01, source "HYG, Gaia DR3 distance".

The neighbourhood's subtitle reads "Gaia DR3 378,775 · HYG 73,556 · NASA Exoplanet Archive
3,277", counted by the catalogue describing each star.

build.ts validateStars now fails a catalogue with more than 1 000 stars without a band (309
today) or without a distance error (439). Dropping G from the Gaia rows gave 379 040 without a
band, and dropping their parallax_error gave 441 216 without an error; both runs failed.

Decoding the catalogue in Node took a median 29 ms before and 24 ms after (nine runs each, within
noise). In the app, five cold boots gave a 654-786 ms long task after the data landed and the
HUD at 1.83-2.07 s.

SenrokaiandClaude Opus 5.5 4c8e4a02f3 Give every planet with a distance a star, from the archive where the catalogue has none
After matching, 4 237 planets still had no star: their hosts are too faint for either Gaia
query (fainter than G 12 past 50 pc) or too far (past 250 pc), Kepler-186 at 177.6 pc among
them. fetchExoplanets now adds one star per such host from the archive's own figures, 3 277
of them, whenever the archive gives a position and a distance:

- position carried back from J2016, where the archive publishes it (741 of the 746 matched
  hosts moving over 100 mas/yr sit nearer their star carried back, a median 0.11" against 3.47"
  as published), and placed at sy_dist;
- magnitude in V (2 999 hosts), else Gaia G (13), the band the catalogue's Gaia stars are
  already in; 265 have neither, 128 KMT, 95 OGLE and 32 MOA microlensing hosts at a median
  6.2 kpc among them, and take the ETL's faint stand-in of 15;
- colour as B-V from the archive's B and V, else from st_teff through a new
  temperatureToColorIndex (Ballesteros 2012, inverted; the Sun's 5 772 K gives 0.65), else
  left to st_spectype;
- ids from 1 070 000 000, past Gaia's two ranges and under the 2^30 validateStars enforces;
  source "exoplanet-archive".

Hosts past 250 pc are included: 399 of the 3 277 are within 250 pc, 1 962 between 250 pc and
1 kpc, 916 beyond. The drawn budget still chooses what is drawn (70 000 of 455 608).

Planets with a star: 2 090 -> 6 327 of 6 354. The other 27 have no distance in either table
(Luhman 16 A, mu2 Sco, PSR B1620-26 among them). Systems in the Solar Neighbourhood readout:
1 450 -> 4 736. validateExoplanets now refuses a catalogue where fewer than 99.5 % of planets
have a host (measured 99.58 %); dropping the added stars fails it at 2 090, and dropping the
composite fill at 6 227. No added star sits within an arcsecond of a catalogue star
(validateMerge's twins stay at 23); 5 of the 399 within 250 pc have one within a minute of arc,
VHS J125601.92-125723.9 (archive 12.7 pc) 5.8" from a Gaia entry at 21.2 pc the likeliest
duplicate.

In the app, searching TRAPPIST-1 or Kepler-186 and picking the star enters a system with its
seven and five planets drawn. gzip -9: stars.bin 5 030 741 -> 5 067 864 B, stars-meta.bin 2 784 614 -> 2 804 064,
stars-index.json 4 003 584 -> 4 015 882, exoplanets.json 342 467 -> 446 532 (host parameters,
both commits).

SenrokaiandClaude Opus 5.5 494fb5616b Find the hosts the catalogue already holds, and name them after their planets' star
The archive's default-parameter rows leave sy_dist blank for 100 planets, TRAPPIST-1's seven
among them, so the matcher could not place a host the catalogue had drawn since the Gaia
nearby query (Gaia DR3 2635476908753563008, 12.47 pc). fetchExoplanets now also reads the
Planetary Systems Composite table (pscomppars) and fills a default row's blank host cells from
it. Only host columns: a composite row takes each column from its own reference, so orbits
still come from the default row alone, one fit per planet. Where both tables give a distance or
a position they agree on all 6 225 and 6 352 rows.

Three hosts the catalogue holds by name failed the distance ratio test because the archive's
sy_dist, from TICv8, contradicts its own parallax: Lalande 21185 (GJ 411) 5.68 pc against
392 mas, Luyten's Star (GJ 273) 5.92 against 263 mas, Struve 2398 B (Gl 725 B) 6.84 against
285 mas. resolveHostStarId now takes the archive's parallax (sy_plx) as a second distance the
ratio test accepts. It is a second chance, not a replacement: 47 of 5 959 systems disagree past
the tolerance, and for faint far hosts the inverse parallax is the worse figure (K2-238: 538 pc
by sy_dist, 6 779 by parallax).

Planets on a catalogue star: 2 071 -> 2 090 of 6 354. The 19 gained are TRAPPIST-1 (7),
GJ 273 (2), GJ 411 (2), Gl 725 B, HD 62509 (Pollux), K2-65, TOI-2267 A and B, and two
brown-dwarf hosts, 2MASS J02192210-3925225 and DENIS-P J082303.1-491201. No planet lost or
changed its host.

A matched host whose catalogue name is a bare Gaia designation now takes the archive's host
name, so search finds TRAPPIST-1, Teegarden's Star, TOI-700, LP 791-18 and K2-18: 575 stars
renamed. validateExoplanets refuses a host that is still only a designation, and the star
assets are rewritten after the exoplanets for that reason; stars.bin and stars-meta.bin are
unchanged. TOI-2267 A and B both land on one Gaia entry, which takes the name TOI-2267 A.

Each planet also carries its host's radius, effective temperature and luminosity (10^st_lum),
and a mass for 6 344 planets instead of 5 474, from the default row where it gives one and the
composite table otherwise, for the star-physics step.

SenrokaiandClaude Opus 5.5 c01d3ec2bc Read OpenNGC's addendum, so the Pleiades and the Large Magellanic Cloud are on the map
OpenNGC keeps the objects no NGC or IC number covers in a second file, addendum.csv, with the
same 32 semicolon-separated columns as NGC.csv. The ETL only ever fetched NGC.csv, so the
brightest deep-sky object in the sky, the Large Magellanic Cloud (V 0.29), was missing while
the Small one was drawn, and so were the Pleiades (M45), the Hyades, the Horsehead and the
Coalsack. fetchDeepSky now fetches the addendum beside NGC.csv, caches it as
openngc-addendum.csv, and runs its rows through the same loop.

Of its 64 rows, 27 pass the existing filters: all 22 named or Messier rows except M40, which
OpenNGC types as a double star, and M102, typed as a duplicate of M101; plus seven anonymous
open clusters brighter than V 9 (H05, H20, H21, Mel071, Mel101, Mel105, MWSC3171). deepsky.json
goes from 463 to 490 objects (galaxies 73 -> 85, clusters 294 -> 306, nebulae 96 -> 99), with
no existing record changed. Messier coverage goes from 106 to 107 of 110. 340 of the 490 have
a distance: the Pleiades 135.8 pc and the Coma Star Cluster 85.9 pc from their parallaxes;
the Hyades and the Local Group dwarfs honestly have none.

validateDeepSky now requires the Andromeda Galaxy and the Small Magellanic Cloud from NGC.csv,
the Large Magellanic Cloud and the Pleiades from the addendum, and at least 107 Messier
objects. Both checks were run against the real catalogue with the addendum removed: the ETL
fails on "Deep-sky object ESO056-115 is missing", and with the required list emptied, on
"Only 106 Messier objects were produced".

In the app, on the dev server: 490 sprites. The Pleiades sprite lies 0.00182 deg from Alcyone
(0.00183 deg from the published coordinates); the LMC 18.4209 deg from Canopus and 26.8215 deg
from Achernar (18.4209 and 26.8215 published); the Hyades 2.2591 deg from Aldebaran (2.2591).
The twelve labelled deep-sky objects now open with the Large Magellanic Cloud and the
Pleiades and include Brocchi's Cluster, in place of h Persei, chi Persei and NGC 2516.

SenrokaiandClaude Opus 5.5 74b93a0428 Fill in the Sun's faint neighbours from Gaia, and fold the Gliese entries they repeat
Gaia's G < 12 cut took a quarter of what lies within 10 pc: the red,
brown and white dwarfs most of the neighbourhood is made of, which the
map only had where Gliese happened to list them. Teegarden's Star was
missing, and with it its three planets' host.

A second query fetches the complement out to 50 pc: G >= 12 or no G,
parallax > 20 mas, with pmra/pmdec so the J2016 -> J2000 propagation
applies. The quality filter was chosen by counting. Parallax over error
> 5 keeps 39 751 of the 39 764 sources that pass the floor, but the Gaia
Catalogue of Nearby Stars (GCNS; Gaia Collaboration, Smart et al. 2021)
rejects 11 752 of them as spurious: median G 20.2, astrometric excess
noise 5.4 mas against 0.15 for the ones it keeps, 6 933 toward the
Galactic centre. So the query joins the GCNS main table (EDR3 astrometry
and source ids, which DR3 carries unchanged) and keeps 28 012 rows; the
error cut stays and costs no GCNS source, brown dwarfs included. The
query has its own row-count floor (28 012) and the row-limit cap, and is
ordered by (phot_g_mean_mag, source_id); a second ETL run reproduced
stars.bin, stars-meta.bin and stars-index.json byte for byte. Its ids
start at 1 050 000 000, clear of the main query's and under 2^30, which
V8 keeps unboxed: numbered from 2 000 000 000 they made the app's boot
task 230 ms longer (medians of five interleaved runs, 1.41 s against
1.18). validateStars now refuses an id outside 0 to 2^30.

The Gliese entries these stars duplicate were not folded: HYG carries
them with positions off by up to a minute of arc and photometric
distances, so they missed the 15" tolerance or failed the distance test.
Their proper motions, which Gliese measured well, give them away:
isSameStar now takes two entries moving within 20 % of each other as one
star up to 60" apart, whatever their distances, brightness still
permitting. Of the 602 Gliese-only rows left without a counterpart, 253
have such a Gaia entry; with every entry shifted a quarter degree, none
does. fetchStars passes HYG's motions only for rows without Hipparcos
astrometry: given them too, 15 Hipparcos stars took a co-moving
companion's Gaia entry and the cross-catalogue pairs under an arcsecond
went from 23 to 35. Of HYG's 1 200 stars fainter than V 12 within 25 pc,
1 024 now sit on a Gaia position (325 before); of the 176 left alone, 43
still have a Gaia entry 3-60" away (218 without the motion rule), some of
them real companions.

Measured on the rebuilt catalogue, against the GCNS (sources with
parallax > 100, 40 and 20 mas):
  within 10 pc  336 -> 372  (GCNS 312; the map adds 60 HYG-only stars)
  within 25 pc  3 652 -> 5 560  (GCNS 5 111)
  within 50 pc  13 702 -> 40 916  (GCNS 40 231)
452 331 stars (+27 214). Proxima, Barnard's Star, Wolf 359, Rigel, Deneb
and Alnilam are all present by name; Teegarden's Star is Gaia DR3
35227046884571776 at 3.83 pc and hosts its three planets. Luhman 16 is
not in Gaia DR3 with a parallax (5353626573555863424 has a two-parameter
solution) and stays absent. 94 more exoplanets find a host (2 071), none
changes host. TRAPPIST-1 is now drawn (Gaia DR3 2635476908753563008,
12.47 pc) but its planets are not yet matched to it.

Merge gate, ceilings unchanged: HYG rows without a Gaia counterpart
12 352 -> 11 554 (ceiling 15 000; 10 886 before the naked-eye stars),
cross-catalogue pairs under an arcsecond 23 -> 23 (ceiling 100). The
gate's comment now accounts for the survivors by magnitude.

gzip -9 sizes against the catalogue before both changes: stars.bin
4 711 922 -> 5 030 741 B, stars-meta.bin 2 576 213 -> 2 784 614 B,
stars-index.json 3 724 855 -> 4 003 584 B (+806 KB, 7.3 %). Boot on the
dev server, five interleaved cold runs: the task that indexes the
catalogue after the data lands, median 1 072 -> 1 182 ms; HUD shown,
median 2 622 -> 2 716 ms. This machine measured 0.82-1.30 s for the
same baseline task today, above audit #25's 627-843 ms. The drawn-star
budget is unchanged.

SenrokaiandClaude Opus 5.5 c64eea0803 Keep every star the naked eye sees, Rigel, Deneb and Alnilam among them
The 250 pc cutoff took 1 543 of HYG's 8 920 stars of V 6.5 or brighter:
1 339 that both surveys put past it and 204 HYG has no distance for. Five
of the fifty brightest stars in the sky were gone (Rigel, Deneb, Alnilam,
gamma-2 Vel, Wezen), and Naos, Sadr, Aludra and Arneb with them, while
11th-magnitude Gaia stars at the same distance were drawn. The cutoff
bounds a download, not what the sky shows.

placementDistancePc now keeps a star of V 6.5 or brighter at any distance,
at the better of its two distances as before: Gaia's where the archive's
Hipparcos cross-match has a usable parallax, Hipparcos's otherwise. Gaia
saturates on the brightest, so Rigel (264.6 pc), Deneb (432.9), Alnilam
(606.1), Wezen (492.6), Naos, Sadr, Aludra and Arneb sit at their
Hipparcos distance. 1 502 HYG rows come back, 165 of the 206 without a
Hipparcos distance among them because Gaia measured them; 36 fold into a
Gaia entry. 41 naked-eye stars stay out because neither survey gives them
a distance: beta Phe, Polis, Mu Cep, Rho Cas, Eta Car, Alp Cam, Phi Cas,
Chi Aur, Psi-1 Aur, theta-1 Ori, Omi-1 Cen, 66 Ori, 16 Sgr, 10 Sge and 27
HD stars.

Measured on the rebuilt catalogue: 425 117 stars (+1 466), 8 301 of them
past 250 pc (+1 466), the same 336 within 10 pc and 3 652 within 25 pc.
Merge gate: 12 352 HYG rows without a Gaia counterpart (was 10 886; the
ceiling of 15 000 is unchanged, and its comment now counts the naked-eye
stars among the survivors) and the same 23 cross-catalogue pairs under an
arcsecond. Five more exoplanets find their host: HD 81817 b and c,
HD 158996 b, HD 208527 b, HD 220074 b. gzip -9 sizes: stars.bin
4 711 922 -> 4 728 315 B, stars-meta.bin 2 576 213 -> 2 587 977 B,
stars-index.json 3 724 855 -> 3 731 763 B.

The brief behind this also asked to cut once on the best distance, which
would drop the 6 835 stars Hipparcos puts inside 250 pc and Gaia outside.
Those already sit at Gaia's distance (4eb61ff), so nothing is misplaced,
and they stay.

SenrokaiandClaude Opus 5.5 c38a42cbcb Fix what the review of this branch found, starting with the pick rule it only claimed
The off-screen rule for clicks was described in 3f0abf8 and in the pull request, but only its
comment was committed: pickAt still let the slop reach past the frame. The mutant that was said
to catch it matched nothing, and an unrelated flaky test failed instead. The frame test is now in
pickAt, before the slop, and its test fails without it (star at NDC 1.01, click at 0.995).

Venus, Uranus and Pluto turned forwards: Horizons states a retrograde spin twice, by a negative
rate and by an obliquity over 90 degrees, and both were applied. The period's sign is now used
only when no obliquity is known. Measured on the live markers, spin axis against orbit normal is
cos(obliquity) for each: Venus -0.999, Uranus -0.135, Pluto -0.494, Earth 0.917.

Moons listed as rates rather than "Synchronous" drifted about 5 degrees an orbit and Titan did not
turn: every moon is now locked at its Kepler period. Pluto's obliquity comes from IAU WGCCRE 2015,
Horizons gives none.

Also:
- the star's light is white at pi, not a warm 2.2 that left the photographs dim;
- procedural textures are 128x64, not 512x256 that froze the main thread ~60 ms a body;
- Io, Pluto, Titan and Deimos lose their "maps", which were disc photographs with black sky;
- an exoplanet with only a mass gets a radius from it (M^0.55, capped at Jupiter), not Earth's;
- the clock knows when it has left the present even once back at real time, so the date and
  "Back to now" stay up.

SenrokaiandClaude Opus 5 468c98b14a Surface the system view with the photographs it already had, lit by its star
Every body in the system view was an unlit sphere wearing a 32 by 16 pixel
procedural texture — the size chosen when a marker was a few pixels across and
what survived was its average colour. The thirteen real photographs in
`src/assets/textures/bodies/` were used only by the detail page. So Mars was a
pale grey ball with invented polar caps while its own NASA mosaic sat unread in
the repository, and nothing had a day side or a night side.

Each marker now takes its own photograph where one exists, at the size the
detail page uses, and the derived texture only where none does — the five moons
no probe mapped, and every exoplanet, none of which has ever been imaged. The
material is lit, and the light is a point at the star, so each world shows the
terminator where it really falls.

The light does not fall off with distance. Under the inverse square that real
light obeys, Neptune receives a thousandth of what Mercury does and reads as
black; the map is a set of worlds to look at rather than a light meter, so each
is lit as a photograph of it would be. That is the same concession the pixel
floor makes for size, and it is only about brightness: the *direction* is real.

Spheres are 32 by 24 rather than 16 by 12, since at true scale a body is drawn
anywhere from a pixel to the whole frame and the old silhouette was visibly
faceted at the near end.

SenrokaiandClaude Opus 5 4b276e44a5 Give the map a clock, so the sky it computes can be watched
The orbits and the rotations are both functions of a date, and the only date the
map ever asked for was this instant. So a view built on propagated ephemerides
showed a still picture: Earth turns 15 degrees an hour and takes a year to go
round, and a reader watching for a minute saw nothing move at all.

`TimeStore` is that date, at a rate the reader sets: real time, an hour a
second, a day a second, a month a second. It is read once a frame rather than
held in a signal — it changes continuously, and a signal changing sixty times a
second would ask the whole HUD to re-render for a number nothing is watching.
Changing the rate re-anchors rather than rewinding, so speeding up and slowing
down never jumps the sky, and "Back to now" returns to the world's own time.

Measured in the app, three seconds of watching in the Sun's system:

| rate | sky elapsed | Earth turned | Jupiter moved |
|---|---|---|---|
| real time | 0 | 0 | 0 |
| 1 h/s | 3.0 h | 45.12 deg | 0.0009 AU |
| 1 d/s | 3.0 d | (three full turns) | 0.0222 AU |

45.12 degrees in three hours is 15.04 an hour, which is Earth's own sidereal
rate, and Jupiter's 0.0222 AU in three days is its own orbital speed.

The rates are radio buttons, not toggles: they are one of four, and the native
control carries that to a screen reader and to the arrow keys with no script.
The date joins the strip only while the clock is running faster than the world,
since at real time it is today's, which the reader's machine already says.

SenrokaiandClaude Opus 5 225d676ab0 Turn each body at its own rate, from Horizons' own figures
The view had one rotation in it — the planet on the detail page, at 0.08 rad/s,
a number with no source. Nothing in the system view turned at all.

The data was already on disk: every cached Horizons page carries how its body
spins, in one of five forms. The rate in radians per second is preferred where
it appears, because it is signed — that is how Venus and Uranus are known to
turn backwards — then a period in hours or days, then the `9h 55m 29.711 s`
the giant planets use, and finally the word every major moon here carries
instead of a number: Synchronous. A tidally locked moon's day is its orbit, so
Kepler supplies it from the elements already parsed and the parent it goes
round.

Seventeen of the eighteen bodies come out within 1% of their published period —
Earth 23.934 h, Jupiter 9.925 h, Venus -5832.5 h, Io 42.5 h, Callisto 400.5 h.
Titan is the exception: its page states no period at all, so it is left still
rather than turned at an invented rate.

The axis is the orbit normal tilted by the obliquity about the orbit's
ascending node, which is where an obliquity is measured from and the only line
in the orbit the elements name. The phase at the epoch is published for none of
these bodies, so the face turned toward the camera is not a claim; the rate and
the direction are.

At true rates nothing is visible moving — Earth turns 15 degrees an hour. A
clock the reader can run faster is the next piece, and the audit asks for it
anyway.

SenrokaiandClaude Opus 5 3f0abf8717 Draw the system at true scale, drop the halo, and refuse to enter what is off screen
Three changes to what the system view claims, all of them the same claim: that
the sizes on screen mean something.

**The halo is gone.** It was a sprite sized against the arrival frame — 1.12 AU
for the Sun — so it stayed that wide as the camera closed in and ended up a flat
gradient filling the screen, over the photograph it was meant to dress. It
existed to keep the star visible at a framing that holds the whole system, which
is now handled in pixels instead.

**Bodies are drawn at their own radius.** The old marker size was exaggerated
and scaled to the system span, and clamped: Jupiter and Ganymede both ran past
the ceiling and were drawn at one radius, so every moon orbited inside its
planet, and Phobos and Triton sat entirely within Mars and Neptune. True scale
needs no rule against that — physics already puts a moon outside the planet it
orbits. What it costs is visibility at the arrival framing, where every body is
sub-pixel, so the scene floors each marker at 3 px on screen and holds a moon to
half its planet's drawn size. Measured in the Sun's system: at arrival, planets
3 px and moons 1.5 px, against 3 px for everything before; at Jupiter, the
planet 10.8 px at scale 1 with the Galilean moons on their orbits outside it.

The Sun is drawn at its own radius too. Every other star keeps a size derived
from its innermost orbit, because no stellar radius reaches the app — Gaia's
`radius_gspphot` is the obvious next fetch.

**A click cannot enter a system that is not on screen.** The picker tested depth
but not the frame, and a star's hit area is its drawn size plus a slop, so a
click in the last pixels of the view could fly into a system outside it, with
nothing on screen to explain where it had gone.

SenrokaiandClaude Opus 5 0c5efec505 Measure the ring span along the plane the rings lie in
The span went to `distanceRings` as the target's straight-line distance from the
Sun, but a ring of radius r passes within |r - p| of the view's centre, where p
is how far out that centre is *along* the galactic plane. For a target above the
plane the two differ by its height, so the band was centred on a radius no ring
has — and `ringLabels` picks its bearing by comparing its own in-plane distance
against the innermost ring, a comparison the new first ring quietly broke.

Two comments and a constant, from the same review. A frame short of the survey
edge gets its callout only when its last ring overshoots it: 245 pc does, 235 pc
does not, which is now a test rather than a sentence. The ring count can reach
16, not 14, now that the span need not start at the Sun. And a ring label was
measured as 135 px of star name when "50 pc" is a third of that, which rejected
rungs a hand's breadth clear of the name: RING_LABEL_REACH_NDC, 0.23, is the
widest of them — "1.5 kpc" with "Survey edge" under it.

Three mutants, three caught. Measured again in the app: unchanged for a star in
the plane (4 labels at 20 pc above it, 7 at 2 pc), and the rings now follow the
plane for one 195 pc above it rather than ringing a place the grid does not
reach.

SenrokaiandClaude Opus 5 337602f606 Make the budget test spend the budget, and bound the probes that earn nothing
The fixture built for "exactly MAX_VISITED stars reachable" was 338 short: its
random cloud leaves clumps the departure never reaches (the LCG gives 12 212
distinct positions for 39 999 stars), so the search settled 39 662 and the
pre-fix code answered `gaveUp: false` too. The test could not fail on the code
it was written to pin — and the mutant that seemed to prove otherwise was
failing to compile, not failing the test. It is now a line of 40 000 a parsec
apart with the island off the line: settled 40 000 exactly, 115 ms, and the
pre-fix code does report a give-up. Both mutants now compile and are caught.

The give-up cap also has to hold while the bisection has earned nothing: the
exception added for that case had no bound at all, so a search could spend the
resolution's own eight full-budget probes — about 17 s of "Plotting…" — where
two used to cost 4 s. Bounded at five. On the repo's crowded-knot fixture:
1.9 s for the unearned ceiling figure with the old cap, 7.2 s for a range the
bisection earned, and five probes is where that lands.

SenrokaiandClaude Opus 5 1a5785fb63 Keep the row cap live for the queries that can reach it
Gating it on `jobsQuery` switched it off for every override that *widens* the
query — which is the only way to fill `select top N` at all. `ETL_GAIA_MAGNITUDE_LIMIT=14`
asks for 500 000 rows, the sky holds more, and the answer is the limit rather
than the filters: exactly what the tripwire is for, and it no longer fired. It
now reads the row limit itself, so only a deliberately smaller slice is silent.

Measured with a synthetic answer of exactly 500 000 rows in the cache, under the
key the widened query hashes to: refused. With the `jobsQuery` gate back, the
same run keeps 500 000 Gaia stars and goes on to publish them.

SenrokaiandClaude Opus 5 dd56eafba4 Answer the review: hold the offer to the same test as the button
`canPlot()` guarded the Plot button and not `raiseTo`, which is the other way
into `plot()`. So with a departure typed but never chosen, clicking "1.8 pc
would reach." moved the range control and plotted nothing: the panel then read
"No route at this range. 1.8 pc would reach." beside a control already set to
1.8. The offer carries the same `disabled` as the button, since it is the same
request by another route.

And the departure guard is trimmed, as the scene trims the same text before
offering matches for it: one space in the field left it looking empty, with no
suggestions to pick from, and Plot dead for no reason on screen.

Measured in the app, from inside Barnard's Star with Sirius as the destination:
offer enabled with the field empty, disabled once "Sol" is typed and never
chosen — a forced click then moves nothing — and enabled again when the field is
cleared, where it raises the range to 2.40 pc and plots 7 jumps.

SenrokaiandClaude Opus 5 7fba48c808 Answer the review: size the rings to the band the frame covers, and clear the text
The rings are centred on the Sun and the frame need not be. Sizing their step
from how far the frame reaches — 210 pc for a star at 190 with the camera 20 pc
back — gives 20 pc rings at 180 and 200, both outside a frame 19 pc deep, so a
view away from the Sun still had no ring on it and no ladder of labels either.
`distanceRings` now takes the span the frame covers rather than its far edge,
and the step is a fifth of that: 5 pc rings from 165 to 210 for the same view.

Measured in the app, centred on a star 187 pc out in the galactic plane: 4 ring
labels drawn 20 pc above the plane and 7 from 2 pc, against 1 and none before.

The clearance was a radius around the anchor, and a label is a line of text
hanging 135 px to one side of its anchor: at 0.065 NDC apart, past the radius,
"50 pc" printed inside "Alpha Centauri". It is now tested against the span the
name occupies, on the side it hangs, with the radius kept for the pair whose
text runs the other way.

Also from the review: the ladder in the clearance test was built at exactly the
constant it tests, so 1057 of 2000 camera poses would have decided it by float
round-trip error — the rungs now sit 0.02 either side of the rule. And two
comments that were wrong: a frame one step short of the survey edge does get its
callout, and CSS2DRenderer hides a label behind the camera rather than drawing
it at the page edge.

SenrokaiandClaude Opus 5 1a53f26474 Answer the review: say which search gave up, and let the bisection earn its offer
The panel printed "No route at this range." beside the range it was offering —
which is the sentence this branch exists to stop it printing. It was gated on
there being no offer, and a search that gives up usually has one: Sol to
HD 120147 at 4.5 pc spends the budget, offers 4.83 pc, and says there is no
route where a 71-jump route exists. The wording now follows the search at the
range that was asked for, and nothing else.

That needs the two give-ups kept apart, so `least` travels beside `gaveUp` to
the panel: one says the asked range was not searched out, the other that the
search for a range that would work was. HIP 69445 at 3 pc — asked-range search
exhaustive in 44 ms, ceiling probe out of budget — used to read "Too many stars
to search at this range." and now reads "No route at this range.", with nothing
claimed after it.

Two more from the same review. The budget flag was read off the settled count,
so a search that proved a dead end with the last star it was allowed reported a
give-up; it now records why the loop stopped. And the bisection's cap could fire
before a single probe had narrowed anything, leaving the ceiling route's own
longest hop as the answer: star 1000115173 at 3 pc was told to go to 8.00 pc,
the control's maximum, for a crossing that works at 6. It now offers 6.93.

Measured in the app, all three: "Too many stars to search at this range.
4.90 pc would reach.", "No route at this range." alone, and 7.00 pc in place of
8.00. The duplicated dead-end test now asks the question it was named for —
exactly the budget's worth of stars reaching each other and none of them the
destination — and each fix kills its own mutant.

SenrokaiandClaude Opus 5 b7f277ea04 Answer the review: a short answer makes more survivors, and must not be skipped
Three things this got wrong. The direction: truncating Gaia leaves the HYG rows
whose counterpart it dropped without one, so survivors rise — 10 886 today,
12 711 at half the rows, 16 258 at a third — which the comment claimed was the
other way, and which decides whether the 15 000 ceiling can be leaned on at all
(it catches a truncation past about two thirds, and nothing shallower).

The throw: `fetchStars` catches everything a source throws and skips it, so a
truncated CSV was reported as "the archive was unreachable" one step after
`writeStarAssets` had already overwritten the published catalogue. Marked with
`GaiaAnswerError` and rethrown there, so an answer that cannot be worked with
fails the run where it happened. Measured end to end in a throwaway working
directory, 300 000 rows in the cache: fails, names the cache file to delete,
assets untouched. With the rethrow taken back out again: assets written, then
"the archive was unreachable".

The row limit: `rows.length >= ROW_LIMIT` is true for every reduced
ETL_GAIA_ROW_LIMIT, so the tripwire fired on exactly the deliberate slice the
override exists for — and told the operator to raise it. Gated on the same flag
as its neighbour. `ETL_GAIA_ROW_LIMIT=20000` now runs through; without the gate
it dies on the limit it was given.

Also: the row floor names the one cache file it is about rather than a glob that
takes the Hipparcos cross-match with it, and says an edited query is a third
reason it can fire — DEFAULT_QUERY_ROWS now sits under the query it counts.
