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).

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).

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).

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).

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).

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.

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> |

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.

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> |

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.

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.

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.

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.

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.

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.

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.

Size the distance rings by what the frame reaches, and keep their labels off the star names
From the review of #19. The rings are distances from the Sun, but their step was taken from `effectiveDistance`, which under the plan view means the extent of the frame rather than how far the camera is from the Sun. Centred on a star 200 pc out and flipped to 2D, the grid became rings of 2 to 20 pc: not one of them on screen. The step now comes from where the view is centred plus how far the camera is orbiting it, which is the same distance under either projection. The set was also rebuilt while the grid was hidden, and every rebuild disposes the rings and builds every vertex again; it now happens only while the grid is drawn. The ring labels went straight to the overlay: never culled to the frame, and free to land on a star's name. They now have to be on screen and clear of the names already placed, by half the separation two names keep — they are a ladder up one ray a twentieth of the screen apart, and holding them apart from each other would take "Survey edge" off the map.

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.

Answer the review: keep up with flights frame by frame, respect portrait frames, and let links follow an orbit
- Flights: the drawn stars were checked once a label pass, and a flight outruns that. Leaving a system jumps the camera to face another way, then zooms out forty-fold in a second: 74-83% of the stars that belong on screen were missing on the first frames back in parsec space, 33-50% before each re-choice on the way out. While the rig animates, the check now runs every frame. Probe on real flights (Gl 806, Barnard's Star, out): 0.90-1.00 of a fresh choice drawn on screen in flight, 1.00 on the frame of the jump; frame p95 12.2 ms, no long tasks. Choosing for the whole sky during flights was tried first and measured worse (0.15-0.18). - Portrait frames: the turn and pan limits use the narrower half-extent, not the height. - Links: a new drawn set arms the rebuild timer only when none is pending, so a continuous orbit gets a graph at most every 250 ms instead of never; an unchanged set asks for nothing. - The centre-move test lets the first pass happen before moving the centre.

Answer the review: share a graph request asked again, by its range and its drawn list
Graph requests were never shared, on the grounds that the scene never asks for the same graph twice. It does: turning the layer off and on while the worker is busy asks again for the graph already waiting. The new request superseded the old one, and the old one's rejection handler, which finds its request by range and drawn list, wiped the state of the new one: the layer stayed on with no graph. An identical request now shares the outstanding promise, a graph being the same when its range matches and its drawn list is the very same array.

Draw what the camera shows: the budget goes to the stars in view
The drawn set was two spheres, around the view's centre and around the Sun, then the brightest stars anywhere, so most of the budget sat behind or beside the camera: at 30 pc from the Sun 15.8% of the drawn stars were on screen, at 5 pc 9.1%, in a plan view zoomed to 10 pc 3.8%. The same tiers are now taken only from the camera's frame, widened by a quarter (VIEW_MARGIN), with the planet hosts in view drawn first after the pinned stars, so every ring circles a star that can be clicked. The set is chosen again at the label cadence once the view has turned, zoomed or moved half the margin, switched projection or been resized, and once for the whole sky on the way out to the Galaxy. Drawn stars on screen: 74-76% at 30 pc, 73-75% at 5 pc, 66% in the zoomed plan view, 91.5% at the opening view.

Choose the drawn stars in one walk of the brightness order
Same stars in the same order, for less: one walk of the brightness index, reading positions laid out in that order, sorts the view's neighbourhood, the Sun's and the rest as it goes, instead of gathering both neighbourhoods in catalogue order and sorting them. A refocus in the page drops from 11.3 ms to 4.6 ms (median; worst 19.1 to 7.1). This comes before the drawn set follows the camera's turns, which makes refocusing far more frequent.

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.

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.

Give the map a scale bar, and rings that say how far from the Sun
The map had one way to read a distance: the Range readout, a number for how far back the camera is. The local grid's five rings sat at 50 to 250 pc, fixed and unlabelled. They said nothing from inside a 2 pc hop, and nothing past 250 pc now that the Hipparcos stars Gaia places there are drawn. A scale bar now sits under the scale rail. It shows the longest round length (1, 2 or 5 x 10^n) that fits in 120 px, in AU inside a system and in parsecs or kiloparsecs outside. It is measured at the depth the view is centred on, since under perspective every depth has its own scale; under the plan view it is exact everywhere. The local grid's rings are now distances from the Sun, at a round step of about a fifth of the camera's distance and out past the camera: 50 to 350 pc from the opening view, 2 to 20 pc from twenty parsecs out. Each ring is labelled with its distance, on the side facing what the view is centred on, or across the far side of the grid when that is the Sun (the near side is under the camera and out of frame). The survey edge at 250 pc stays called out, as "Survey edge", whatever the step. The rounding lives in one place, scale-bar.ts, shared by the bar and the rings and tested there. Its formatter keeps three significant digits: one digit, enough for the bar's round lengths, printed the 250 pc ring as "300 pc".

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: 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.

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.

Answer the review: the plan view clipped a system, and pulled its neighbours inward
Two more findings against this projection, both of the same shape as the last two: something written to the camera that happens to be live, where the plan view derives from the other one. The system's own depth range — a near plane a five-hundredth of an astronomical unit out, a far plane twenty thousand — was set on the active camera. Entering a system with the plan view already on therefore wrote it to a camera that re-derives near and far from the perspective one every frame, so the range never applied and the system clipped. All three unit-space depth writes go to the perspective camera now, which is the one they are reasoned in. And the ring of neighbour names collapsed toward the middle of the frame. Its placement unprojected a point on the ring, treated the offset from the camera as a direction, and stepped a fixed distance along it — which is a perspective construction. A parallel projection has no vanishing point to step towards: every ray through the frame is the view direction, so normalising threw the sideways part away. Measured before and after, from inside Sol: the two names sat 319 and 335 pixels out under perspective, 104 and gone under the plan, and 323 and 335 with the unprojected point used as what it already is. Verified: build clean, 596/596 unit, 16/16 end-to-end on the branch this merges into, and the ring measured on both projections.
