Read a dwarf with a type and no colour at its type's row of the dwarf sequence
A non-giant with a spectral type but no colour took its temperature off the textbook colour spectralTypeToColorIndex gives its type, read on Pecaut & Mamajek's table, and its bolometric correction off the old textbook anchors. The table puts those colours elsewhere: M8's B-V 1.88 is M5-M5.5 there, 3 001 K where M8 V is 2 570, and the anchors give M8 -3.92 where the table has -5.65. GJ 3655 (M8, 14.35 pc) was drawn at 0.035 solar radii, a third of Jupiter, where its type's row gives 0.106 (Mamajek's M8 V: 0.114). Every O type came out B0's 31 400 K. Both now read dwarfSequenceAtType, which already existed for the giants, and a G magnitude is carried to V at the type's G-V too. On the published catalogue, of the 835 non-giant stars with a band, a type and no colour, those more than 200 K off their type's row go from 21 to 0, those with a radius more than 1.5 times off it from 7 to 1 and a luminosity from 10 to 1 (the one left, Oph 11, is a G-band star). GJ 3849 (dM9) goes from 0.030 to 0.089 solar radii, GJ 3855 (M6.5) from 0.040 to 0.087. Two tests pinned the textbook path and now read the table: M5Ve with no colour is 3 060 K, not 3 106, and K5 tints as B-V 1.15, its row, not 1.105. An O8 star is 35 100 K, its row, not B0's. Controls: reading the temperature through the textbook colour again fails "is drawn at its type's row of the dwarf sequence" (with the three updated tests); reading the correction off the anchors again fails that test alone.

Classify a star for the rows that list it, not every star each time the index is built
The search index and the route index gave every one of the 455 571 stars a subtitle up front through spectralClassification, which filtered the dwarf table afresh on each call; the star field's tints read the same table once per BP−RP star. Both indices now carry the star itself and classify it only for the rows shown (entrySubtitle): eight search results, a few route options. The two filtered columns of the table are built once. Node, over the shipped catalogue, five runs: classifying every star 121-167 ms before, 56-62 after hoisting the table alone; reading the sequence at every BP−RP colour 187-216 ms, now 111-127. In the app on :4302, two cold loads each, the long task when the Search tab opens was 264-380 ms (median 280) before and 164-276 ms (median 171) after; the longest boot task 863 and 875 ms before, 654 and 741 after. Tests: the search spec checks its index holds no classification and the row still reads "Star · ~M8"; the scene spec now reads the route options, and checks its index holds none either. Controls: classifying every star in the search index, doing so in the route index, and route options printing the index's subtitle each fail the named test.

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).

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).

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).

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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> |

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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> |

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.

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". Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> |

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.

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". - TRAPPIST-1: G 15.62, BP-RP 4.90, source Gaia DR3. - Kepler-186: V 15.14, source NASA Exoplanet Archive. 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. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> |

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).

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.

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.

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 (

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.

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.

Give the budget tests room and cells to run in
Both make a search spend its whole 40 000-star budget, twice over in the bisection, and the CI runner timed out at the default five seconds. The crowds are now indexed in cells sized for the ranges asked of them, as the real catalogue is, and the two tests carry their own 30 s timeout.

Tell a search that gave up from a route that is not there
The route search stops after MAX_VISITED stars and returned null, which everything downstream read as "the catalogue holds no chain". On the real catalogue that was wrong for real questions: Sol to HD 120147 (136 pc) at 5 pc is 50 jumps, and the panel said there was no route. The budget also sat under what the shipped catalogue needs, so it is now 40 000 rather than 20 000: both that route and a star at 170 pc are found, and Sol to HD 2626 at 6 pc, which used to be refused after 4.7 s, plots 56 jumps in about 2 s. A search now reports whether it gave up. The range search no longer counts a give-up as proof that nothing routes below it — that is what reported ranges up to 29% too wide — and it stops after two of them, since those are the probes that cost the most and settle the least: for HD 2626 at 3 pc it offers 5.92 pc in about 4 s, against 6.13 pc in 4.7 s. At the panel's widest range the refused route and the range search are the same question, so it is asked once. Where nothing can be said, the panel says "Too many stars to search at this range." rather than claiming there is no route.

Answer the review: budget in drawn pixels, re-ask when the budget moves, sort only the band it runs out in
- The budget counted CSS pixels; lines are drawn in device pixels, so a screen scaled to 150% or 200% drew 1.5-2x the calibrated line. It now counts the canvas's drawn pixels. - A graph was re-asked only when the drawn stars changed, so with a star budget covering the whole catalogue, or a resize, its budget and centre stayed wherever the layer was turned on. A view that chose its stars again now asks, and a graph is rebuilt when the stars, the range or the budget changed (the budget by more than half the margin, or its centre by more than 5 pc). - From inside a system the budget was worked out in astronomical units about the system's origin. Graphs are now asked for in parsec space only; the flight back out asks. - Comparing budgets let a request re-asked with a slightly different one supersede its twin, and the twin's rejection cleared the state of the request that replaced it. A rejection now clears it only for the latest request. - The worker sorted every link to keep a few thousand, 2.2x an unbudgeted build. It now bands links by distance, keeps every band before the one the budget runs out in, and sorts only that one: 142-168 ms on the real catalogue against 233-388 ms, 103 ms unbudgeted, returning early when all fit.

Budget the jump-link layer in pixels of line, nearest the view's centre first
With the drawn set following the view, the layer at 8 pc cost the integrated Radeon 503 ms a frame at 30 pc from the Sun. Measured, the cost follows the length of line on screen (about 10 ms per million pixels near the Sun), not the number of links: 100 000 links were 12 ms at the opening view, 25 000 were 61 ms at 30 pc. So the budget is a length: a million pixels, turned into parsecs at the depth the view is centred on, spent on the links nearest that centre by their nearer end. Orbiting with links at 8 pc on the iGPU: 12-18 ms p50 at every pose measured, no long tasks.

Link only the stars that are drawn
The jump-link graph linked the whole catalogue: 3.7 million links at 8 pc, 7.4-7.8 s in the worker and a 443-515 ms frame on the main thread when they landed, and most of them between stars that were neither drawn nor clickable. A graph request now carries the star field's drawn stars, and the worker links only those, over an index of its own with cells as wide as the range. The scene asks again once a new drawn set has held still for 250 ms. The renderer is handed the graph's bounding sphere instead of computing it: three.js walked every vertex on the main thread in the first frame that drew a new graph, 48-55 ms at 8 pc.

Answer the review: send the worker one request at a time, keep only the latest, and never wait for a dead one
The adversarial review confirmed three defects in this PR, all reproduced in the browser. 1. Superseded graphs queued up in front of routes. The worker answers messages one at a time and cannot drop one it has started. With the jump-link layer on, every pause on the range slider posted a full graph build, seconds of work at 6-8 pc. Answers no longer wanted were thrown away only once built. A route asked for afterwards waited behind every one of them: a one-jump route took 44 s. RoutingClient now holds requests and sends them one at a time. While one is out, only the latest of each kind waits: a newer graph replaces an older one before it is ever built, and the older promise is rejected with SupersededRequest. Routes go ahead of graphs. The same question asked again while outstanding shares the answer rather than being worked twice, as when the layer is turned off and on during a build. The same scenario in the browser (layer on, range stepped 5 -> 8 pc with 400 ms pauses, then Sol to Proxima): the route came back in 110 ms. The worker was sent "links 3, links 5, route, links 8"; 6 and 7 were never built. 2. A worker that failed left the panel stuck. With no error handling, a worker that failed to load (a 404 on its chunk after a redeploy) or threw left "Plotting…" and a disabled button for good, and a graph at a range could not be asked for again. The worker now answers an exception with a 'failed' message, which rejects that request. A worker that fails to load or dies is abandoned, and what it left outstanding, and everything asked afterwards, is answered in place. The scene releases the panel when a route fails, and forgets a graph range that was never drawn so it can be asked for again. 3. Nothing type-checked the worker. The application builder never reads webWorkerTsConfig, and bundles the worker with esbuild, which strips types without checking them. tsconfig.app.json leaves the file out. A type error in the worker shipped. `npm run worker:typecheck` (tsc -p tsconfig.worker.json) now runs in CI beside the other project checks. webWorkerTsConfig is removed from angular.json, since it only suggested that something checked the worker. Tests with a fake worker cover one request at a time, a waiting graph replaced and a route sent ahead of it, a question shared, a failure rejected and the next request sent, and a failed worker's requests answered in place. A scene test covers the panel released after a failed route. Negative controls, each caught: several requests sent at once, a waiting graph kept, graphs ahead of routes, a question asked twice, a failure answered as a success, a failed worker waited on, the panel left pending, and a type error in the worker (caught by worker:typecheck).

Answer the review: pin by the index the neighbourhood holds, and choose again only when it can matter
The adversarial review confirmed three costs this PR added, all reproduced in the browser. - The first pinned refocus stalled the first flight of a session. The renderer built its own id-to-index Map of 423 651 entries the first time a star was pinned, which is at the first selection, inside the approach flight. The worst frame was 47-103 ms, and the Map stayed as a second copy of a lookup the scene already had. The scene now pins by catalogue index, through the StarNeighbourhood it builds at load (new `indexOf`), and the renderer takes indices. First selection, measured in the browser: worst frame 18 ms. - At galactic scale every label pass rewrote the drawn set. The view centre sweeps hundreds of parsecs a pass there, far past any star, so each pass chose the same 70 000 stars again and uploaded 2 MB to the GPU: 11 times on the flight out to the Galaxy. The scene no longer refocuses at galactic scale, where the whole catalogue is a few pixels, and the renderer leaves its buffers alone when the drawn set is unchanged. Flight to the Galaxy: 2 refocuses, no frame over 50 ms. - At load the same set was chosen twice: once by the renderer's constructor around the Sun, and again by the first label pass, centred on the Sun. The scene now records the constructor's choice as the current focus. Tests: the buffers keep their version for an unchanged set, no refocus at load, none at galactic scale, and pins arrive as indices. Proxima's id in the scene spec now differs from its index, so a lookup by id cannot pass for one by index. Negative controls, each caught: an unchanged set rewritten anyway, a refocus at galactic scale, the boot choice not recorded, and pins passed as ids.

Merge branch 'perf/label-scan' into feat/drawn-set-follows-view
The label fix turns the brightness order into an index with positions and ids laid out beside it. The star field only needs the order, so it is handed `.order`. Both sides added scene tests in the same place; both are kept.

Answer the review: walk the brightness order in memory order, and stop at the fifteenth label
The adversarial review confirmed a regression in this PR. Near the Sun, the label pass became three to four times slower than the scan and sort it replaced. Within about 11 pc of the Sun, and in any plan view zoomed tighter than that, the label radius clamps to 4 pc. That sphere holds a few dozen faint dwarfs deep in the brightness order, so the walk rarely finds fifteen stars to name and reads nearly the whole catalogue. Reading the star objects in brightness order jumps all over memory, so a full walk took 19-25 ms against the old 5-6 ms. The review also found that spreadLabels checked the label count at the top of its loop. After placing the fifteenth label it asked for a sixteenth candidate, which near the Sun can lie at the far end of the order. brightnessIndex now lays each star's position and id out beside the brightness order, in that order. The walk tests stars from those arrays in sequence and reads a star object only when it yields one. spreadLabels breaks straight after placing the fifteenth label. Measured on the real catalogue with the label logic reduced to what decides placement, camera at the given distance from the Sun (old sort / this PR as first pushed / now): 2 pc 4.9 / 24.7 / 2.5 ms 5 pc 5.7 / 23.0 / 3.1 ms 10 pc 6.3 / 18.2 / 0.95 ms 307 pc 22 / 0.01 / 0.00 ms (the opening view) The labels are identical in every case. Now faster than the old sort at every distance. A new scene test counts the candidates spreadLabels takes: exactly fifteen for fifteen labels. Negative controls, each caught: positions one axis off, ids in catalogue order, the selected star dropped, the radius edge excluded, and the count checked before taking a candidate.

Plot routes and build the jump-link graph in a Web Worker
Route plotting ran on the main thread, and so did the jump-link graph: - the range search for a far target, HD 2626 at 236 pc, takes 4-5 s; - the graph at 8 pc is 3.7 million links, 6-10 s to build, then as many link objects again to turn into vertices. The map stopped for as long as either ran. A Web Worker now does both. RoutingClient sends it the catalogue's ids and positions once, and it keeps its own spatial index. A route question comes back with the route, or with the range that would open one. A graph comes back as one Float32Array of segment vertices, transferred rather than copied. On the scene side, only the latest route request is shown: an earlier answer arriving later is dropped. Only the graph for the range last asked for is drawn. The Routes panel says "Plotting…" and holds its button while a request is out. collectJumpLinks gave way to jumpLinkSegments, which writes the vertex pairs straight into floats rather than building link objects first; the scene was its only caller. The routing module (routing.ts) is the message protocol and the one function answering it, so the worker is a dozen lines, and the same answers are worked out in place where there is no Worker, as in the unit tests' DOM. The worker is built with its own tsconfig, as the Angular builder expects.

Draw the stars around wherever the view is, not only around the Sun
The star field draws a budget of the catalogue: everything within 25 pc of the Sun, then the brightest of the rest. That choice was made once, at load, around the Sun, and never again. On the Gaia catalogue it left most of the map empty wherever the view went: - a region 150 pc out drew 49 of the 442 stars within 25 pc of it; - a plotted route ran through stars no one could see or click. Sol to Almach at 8 pc passes 19 stars and drew 6, Sol to Mirfak 11 of 26; - a search for a faint star flew the camera to an empty point. The drawn set now follows the view. The scene chooses it again at the label cadence, once the orbit target has moved more than 5 pc or the pinned stars have changed. The budget goes, in order, to the selected star and the stars of a plotted route, then everything within 25 pc of where the view is centred, then the same around the Sun, then the brightest of the rest. The instance buffers hold the budget and are rewritten in place. Checked in Chromium on WebGPU, framing Mirfak from 12 pc: with the set chosen around the Sun, 122 of the 649 stars within 25 pc were drawn; following the view, all 649. At the opening view the drawn set is the same as before. A refocus takes 9 ms in the browser (5 ms of it choosing). The first version took 16-36 ms in the browser, a visible hitch during a flight. Most of that time went on walking the 423 651-star brightness order once per neighbourhood, out of catalogue order, and on recomputing 70 000 colours. Now both neighbourhoods are gathered in one pass in catalogue order and sorted on their own, and colours and sizes are computed once for the whole catalogue. The brightness order itself sorts a typed copy of the magnitudes, taking 83 ms at load instead of 104-139 ms. STAR_RENDER_BUDGET is now 70 000, and its comment gives the measurements behind it rather than "currently set to the whole catalogue", which stopped being true when Gaia landed. At 1920 x 1080 on a Ryzen 7700X: - on the RTX 4080, the whole catalogue costs the same 6.1 ms a frame as the budget; - on the processor's two-core Radeon, standing in for an entry-level laptop, every 100 000 stars costs about 4 ms: 112 fps at the budget, 44 at the whole catalogue, and the same under WebGL2; - drawn whole, the opening view turns into a grey wash that buries the labels and the host rings.

Name the brightest stars by walking one order, instead of sorting 60 000 five times a second
The star labels are refreshed every 0.2 s. Each pass filtered the whole catalogue to the stars within the label radius, sorted them by magnitude, and turned every one into a label object, all to place at most fifteen. At the opening view the radius holds about 60 000 stars, so each pass was a 55-70 ms task on the main thread. A CPU profile of the opening view, on a Ryzen 7700X with an RTX 4080, counted 29 tasks over 50 ms in 6.7 s, one every 230 ms; updateLabels took 23% of the main thread. That is the stutter the frame-time bench measured on every GPU and every render budget. The catalogue is now sorted by brightness once, when it loads. brightestWithin walks that order and hands stars over lazily, and spreadLabels already stopped once it had placed fifteen labels, so a pass reads only the stars it looks at. The output is the same as before: the same stars, in the same order, with ties in catalogue order, the selected star named wherever it is, and a star exactly on the radius included. The spec checks it against the filter-then-sort it replaces. Stars are no longer scanned at all when the view is at galactic scale, where the result was thrown away. Profiled again on the same view: 0 tasks over 50 ms, and the scene's per-frame work over the window dropped from 2 028 ms to 342 ms.

Route with A* over numeric cell keys, so a route can reach past the Sun's crowd
The route search widened evenly from the departure, Dijkstra-style, with a budget of 20 000 stars. On the Gaia catalogue those are all within about 40 pc of the Sun, so it found no route to anything farther at any range: Sol to Mirfak (155 pc) failed at 3, 8, 15 and 30 pc alike. Every failure then asked minimumRangeBetween what range would work. That search widened the same way with a 30 pc ceiling, and it ran for up to a minute on the main thread before giving up with nothing. routeBetween is now an A* search. Each star is queued by the distance travelled to it plus the straight line on to the destination, on a binary heap rather than a linear scan of the frontier. It heads for the destination instead of flooding the core around the departure. minimumRangeBetween bisects the range, one routeBetween per step, because whether a chain exists can only become truer as the range grows. Its answer is always the longest hop of a route actually found, so a range it names always opens one. Its ceiling is now the Routes panel's own maximum, MAX_JUMP_RANGE_PC: a range the control cannot be set to is no answer, and raiseTo already clamped any figure above it. The spatial index keys its cells by one number packed from their three indices instead of an "ix,iy,iz" string. A search visits up to 125 cells for every star it expands, and building those strings was half of what a route cost. forEachWithin hands neighbours over unsorted and uncollected, which was most of the other half; within is now that, gathered and sorted. The no-route line said nothing in the catalogue bridged the gap; it now says no chain of jumps up to the panel's maximum reaches the star, which is what was searched.

Draw each HYG star at Gaia's distance, and keep the ones Hipparcos misplaced
HYG and Gaia were both cut at 250 pc, each on its own distance. A star Hipparcos put at 200 pc and Gaia at 300 was kept by the first, never downloaded from the second, and drawn at 200. That is where 83% of the 9 691 mid-magnitude HYG stars without a Gaia counterpart came from, and at the median Hipparcos had them a third too close. The mirror case, Hipparcos outside and Gaia inside, dropped the HYG row and left its Gaia entry anonymous. Gaia's own Hipparcos cross-match (hipparcos2_best_neighbour, a fixed DR3 table of 99 525 rows) gives a usable Gaia distance for 97 751 of them. placementDistancePc keeps a star either survey puts inside the cutoff, and draws every kept star at the better measurement, inside the cutoff or not. 57 121 HYG stars now sit at Gaia's distance. 6 833 of them are past 250 pc: Zet Per 230 -> 259 pc, 35 Ori 137 -> 330, 44 Cnc 223 -> 613, and the farthest, HIP 69445, at 8.7 kpc. 3 666 stars that Hipparcos put outside are now kept, and 3 656 of them give a Gaia entry its name. The cross-match is required rather than skipped when unreachable. Without it, every one of those stars would move back to its Hipparcos distance, and the published map would flip with the archive's availability. The ESA TAP answered it with a 500 at first and in 102 s on the next try. So fetches now retry 5xx and network failures twice, after 30 s and 120 s, in the fetch every source goes through. The refresh job also carries the Gaia DR3 responses from run to run in the Actions cache: the release is frozen, and a live re-fetch has already reproduced stars.bin byte for byte. 423 651 stars (+10), 61 168 HYG rows folded into Gaia entries (+3 656), 351 597 unnamed designations (-3 656). 10 886 HYG survivors and 23 unmerged pairs under an arcsecond, both inside the merge gate's ceilings. The same 1 972 exoplanets have a host; KELT-4 A b and MWC 758 c now sit on their named star. The HUD's "Radius" becomes "Survey radius": 250 pc is where Gaia is surveyed to, and no longer the edge of the map.

Answer the review: a name two stars answer to names neither, and NaN is not a proper motion
Three guards the matcher was missing, none of which changes a byte of the regenerated data — the ETL re-run after them is identical — and all three now have a test that fails without them. A proper motion that is not a number poisoned every comparison rather than one: NaN loses every `<` it appears in, so `cosine < minCosine` was false for every star, each one reached the distance guard, and the last one in catalogue order won — a confident wrong answer, order-dependent, where the honest answer is "no match". The archive's own parser never produces one (parseOptionalNumber maps a blank cell to undefined), but the matcher is exported for offline re-cross-referencing and a caller reaching for bare Number() is exactly the coercion the CSV helper documents as having caused two prior bugs. An unusable motion now reads as no motion. Normalizing a name strips the dot, so `Gl 55.2` and `Gl 552` — two stars 135 degrees apart — share one key, and the index kept whichever came last; 64 such groups exist in the catalogue, among them `Gl 84.1A`/`Gl 841A` and `HD 96600` twice. A name that names two stars names neither, so ambiguous keys are dropped and the query goes to the sky, where direction settles it. No archive hostname lands on one today, which is why the data is unchanged. And the cache is keyed by the whole request rather than the query alone, here and in gaia.ts: fetchTextCached records only that some response arrived, so an endpoint edit would have kept serving the old host's bytes — the same silent staleness the query hash was added to close. The tests now discriminate what the comments claim. Eight mutants, each caught: judging only the published position, only the carried-back one, judging each star on its worse epoch rather than its better, letting a distance-rejected star claim best-so-far and shadow the true host behind it, an unguarded proper motion, a last-wins name index, a fixed angular tolerance instead of a transverse one, and no distance guard at all. The GJ 887 test grew a decoy standing halfway along the star's own track: it is nearer than Lacaille 9352 at the published position and nearer at the worse of the two epochs, so it wins unless both epochs are tried and the better one decides — the property the test's comment had been claiming untested.

Match exoplanet hosts on the sky, at both epochs the archive might mean
The host cross-reference matched in 3D, nearest star within half a parsec. That is the wrong space for the same reason the star merge learned it: a direction is measured, a distance is inferred. At 170 pc half a parsec is a ten-arcminute cone, wide enough to hand the planets of stars our catalogue does not carry to whatever bright star floats nearest — HATS-6 b sat on HD 39500, seventy arcseconds away. At 60 pc it is tighter than the routine disagreement between the archive's Hipparcos distances and our Gaia ones, which is how four bright giants (7 CMa, HD 81688, omi UMa, xi Aql) lost their planets and GJ 15 A's landed on a neighbouring entry. Hosts are now resolved like stars are merged: by name first, then the nearest star on the sky within a transverse budget — angle times the archive's distance, 0.01 pc — whose distance does not flatly contradict the archive's (the merge's own 50 % ratio). The budget is transverse because the dominant error is proper motion over an epoch difference, a physical displacement that is the same in parsecs at every distance: as an angle it is 60" for Proxima and 2" for a host at 100 pc. Measured on the 504 hosts whose archive name matches a catalogue name outright, true pairs reach 3.4e-3 pc; shifting every host a quarter of a degree finds nothing else within 0.01 but Proxima's own entry, whose budget at 1.3 pc is wider than the shift. The archive never says which epoch a position is for, and they are mixed: alf Tau and GJ 273 publish J2000, HD 133131 and TOI-2459 publish Gaia's J2016. So the query asks for sy_pmra/sy_pmdec too, tries each position at both ends of those sixteen years, and judges a star on whichever is closer. Guess one epoch and a fast star's planets land on a companion: J2016 puts Aldebaran's on Gl 171.1B, J2000 puts GJ 15 A's on a Gaia entry 15.9" out. 1 972 of 6 354 planets now sit on a host, 1 548 before: 432 gained, 26 on a better star (GJ 15 A to Groombridge 34, GJ 676 A off its companion, HD 19994 to 94 Cet), 8 lost — six false 3D matches to stars the catalogue never contained, and GJ 273 b/c, whose archive row says 5.92 pc for Luyten's Star at 3.79: a distance in flat contradiction is exactly what the ratio guard exists to refuse, and the number to fix is upstream. The 2 pc "rematch" apparatus is gone. build.ts recomputed every match after fetchExoplanets had already written the file — at a different tolerance, so the log reported a match count the data did not contain — and the offline entry point that persisted it had no caller. One matcher, one set of constants, used once. The archive cache is now keyed by a hash of the TAP query, so a response cached before the proper-motion columns cannot serve rows without them, where a missing cell would quietly read as "does not move"; the row's astrometry is stored with each planet, which is what made these tolerances measurable offline in the first place.

Answer the review: direction settles distance, brightness is one-sided, and a lost id stops the scene
Three findings from the adversarial review of the merge, all reproduced. The distance test was hiding 1 489 stars that sit under an arcsecond from their Gaia entry with a Hipparcos parallax off by half — thirty of them at a false few parsecs from the Sun (HIP 82724 at 3.7 pc, where Gaia has it at 62.8) — and the first audit did not see them because it counted residual doubles through the same 50 % filter. Under three arcseconds the distances are now not consulted: a coincidence of direction that close is never chance at this depth (the quarter-degree shift finds none), and the parallax is the thing to fix. Brightness keeps its say at any separation, and is now one-sided: a folded entry may be five magnitudes fainter (a red dwarf in V against G) but not one brighter, because an entry a magnitude brighter than what is already at that spot is a primary Gaia does not carry — Almach, Alfirk and Ashlesha had all been folded into their companions' entries, 93 in all. The sky grid wraps at 0h. The Gaia query orders by source_id after G, so the row order — and the ids assigned from it — is a function of the archive's content rather than of the server's plan for 20 064 ties; the cache key is a hash of the query. And a bookmark to a star id the catalogue no longer holds — 56 000 Gaia ids change with this — sent the scene through reconcileSelection, enterSystem, its decline, finishTransition and reconcileSelection again until the stack overflowed. The selection is cleared instead, at the one place every path goes through. Regenerated: 423 641 stars, 57 512 HYG identities on Gaia positions, no HYG id or name lost, no star within 20 pc left with an unclaimed Gaia entry under an arcsecond. 403 HYG survivors still have an unclaimed Gaia entry within 60": 13 under an arcsecond, where the brightness guard does not trust HYG's magnitude, and the rest components 3" to 60" from their counterpart.

Bring Gaia to HYG's epoch before merging, and keep a star's name when it matches
Gaia DR3 gives positions for J2016.0, HYG for 2000.0, and the merge matched them on the sky to one arcsecond without propagating any proper motion. Sixteen years of motion is 62" for Proxima and 166" for Barnard's Star, so every star faster than ~62 mas/yr — most of the nearest ones — was kept twice, some 23 000 in all. The slow ones were matched, and lost: the merge kept Gaia's row whole, so 102 proper names, 1 336 Bayer/Flamsteed names and 32 000 spectral types became "Gaia DR3 <id>" and "Unknown", and 92 named exoplanet hosts handed their planets to their anonymous twin. Gaia is now asked for its proper motions and carried back to J2000 before it leaves the fetcher. HYG is placed from its own x/y/z columns, which are right where its `ra` is not: that column was carried from the Hipparcos epoch without the cos δ its motion needs, 17.9" off for Proxima. A match combines the two entries — Gaia's position, HYG's name, type, magnitude, colour and id — instead of choosing one. The tolerance is 15" with a five-magnitude guard, both set by measurement: 55 457 pairs sit under 1" once the epochs agree, the Gliese-only entries up to 12" (Ross 248), shifting every entry a quarter of a degree finds 16 chance neighbours at 15", and the guard keeps Sirius out of Sirius B's entry. Entries of one source are never merged with each other: the 1 411 Gaia doubles resolved under 1" are two stars, not one. Regenerated: 425 071 stars (was 447 410), 56 082 of them Gaia positions carrying HYG identities; no HYG id or name lost; the sixteen stars nearest the Sun carry no survey designation; 196 residual doubles, all components 17" or more from their counterpart. Five planets of four bright giants (7 CMa, HD 81688, omi UMa, xi Aql) lose their host link: their Gaia distance sits 0.7–1.1 pc from the archive's Hipparcos-based one, past the 0.5 pc the host match allows. Matching hosts on the sky rather than in space, as the merge does, is the follow-up.

Name the neighbours that have a name, before the ones that only have a number
The neighbour ring exists to say where you are. Since the catalogue refresh it has been spending one of its four places in Sol on "Gaia DR3 5853498713190525696" -- a nineteen-digit survey id for the star printed beside it as Proxima Centauri, the same star twice -- and that duplicate row pushed Barnard's Star off the ring altogether. 91.9% of the refreshed catalogue is named that way. Named stars now come first, and survey designations fill in only where fewer than four named ones are in reach. The line between the two is the one the catalogue format already draws: a name is a designation when it is what the star's source would generate for it. Judged by the prefix rather than by rebuilding "prefix id" from the row, because the number after "Gaia DR3" is the survey's own id, which the 32-bit row id cannot hold -- a round trip through the id would have called every one of those stars named. The preference lives on the index as `nearestPreferring`: the preferred pass exhausts the search before the fill runs, so a named star is never outranked by a nearer unnamed one. That is the whole point of asking. The end-to-end spec names Barnard's Star again, on purpose. The four nearest named stars to the Sun are a fact about space, not about which catalogue was refreshed last, and without this change that is exactly the label that vanished -- checked by running the spec with the preference stashed: it fails on that line, and passes with it back. npm test 609/609, npx playwright test 16/16 under CI=true --workers=2.
