+# Accurate planet positions — implementation plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: use superpowers:subagent-driven-development under the
+> lean protocol in `docs/superpowers/conventions/sdd-execution.md`. Steps use checkbox (`- [ ]`) syntax.
+
+**Goal:** The eight planets match JPL DE (Horizons) to ≤ 1,000 km over 1900–2100, Earth wobbles about
+the Earth–Moon barycentre, and every orbit trail stays through its body.
+
+**Architecture:** Each planet's position is today's Keplerian position plus a generated correction
+series: a cubic polynomial plus fitted sinusoids, about 17 kB of constants. The correction is
+evaluated in `deriveBodyStates`. A one-row pair table subtracts the Moon's reflex from Earth. Orbit
+trails anchor on the snapshot body position, so they follow both corrections without needing to know
+about either.
+
+**Tech stack:** TypeScript, Vitest, tsx tools, the JPL Horizons API.
+
+**Spec:** `docs/superpowers/specs/2026-10-04-accurate-planet-positions-design.md`
+
+## Global constraints
+
+- Accuracy: ≤ **1,000 km** from Horizons for every planet over **1900-01-01 → 2100-01-01**. The fit
+  stops at ≤ **900 km** on its sample grid, and the tool verifies every planet on the dense 1-day grid
+  and throws above 1,000 km.
+- Outside the span the correction is **frozen at its edge value**: clamp `simDays` to
+  `[startJd, endJd]`. No fade and no new setting.
+- Horizons query: `EPHEM_TYPE='VECTORS'`, `CENTER='500@10'` (Sun centre), `REF_PLANE='FRAME'`
+  (equatorial ICRF), `TIME_TYPE='UT'`, `OUT_UNITS='KM-S'`, `CSV_FORMAT='YES'`, `VEC_TABLE='1'`.
+  - Targets: Mercury `199`, Venus `299`, Earth–Moon barycentre `3`, then system barycentres `4`–`8`
+    for Mars through Neptune.
+  - Fetch 1-day steps in 50-year chunks, retrying each chunk up to 5 times.
+- `OBLIQUITY_DEG = 23.4392911`.
+- Earth–Moon pair: `secondaryMassFraction = 1 / 82.30057`, the Moon's share of the pair mass.
+- `simDays` stays a UTC Julian date. No runtime TDB conversion: the UT query absorbs the offset.
+- Conventions: one symbol per `utils/` and `@types/` file, `type` and never `interface`, and pass and
+  frame files export only their one symbol.
+- Prep (Tasks 1–2) is a **separate PR** on branch `accurate-planets-prep` off `main`. This spec and
+  plan are committed there too. Features (Tasks 3–6) go on `accurate-planets`, stacked on the prep
+  branch. Never commit on `main`.
+
+## Review focus
+
+1. **Dates outside 1900–2100** (a tour in 1850, a scrub to 2200). Positions stay finite and equal
+   Kepler plus the frozen edge correction, with no jump at either boundary. Tests are in Task 3.
+2. **A camera parked at an Earth surface site with the clock running.** The site keeps its offset from
+   Earth while Earth wobbles. Tested in Task 6.
+3. **Moon, Hubble and the easter eggs after the Earth reflex.** Each still sits on its own trail,
+   because its trail is centred on the reflexed Earth. Tested in Task 6.
+4. **Any element-row edit or frame change without regenerating.** The Horizons check fails loudly
+   instead of drifting silently. Tested in Task 6.
+5. **Chunk seams in the Horizons fetch.** The duplicated boundary row is dropped exactly once, with
+   no gap and no duplicate. Tested in Task 4.
+

+
+## PR 1: prep (`accurate-planets-prep`)
+
+### Task 1: Orbit trails anchor on the snapshot body position (P1)
+
+**Files:** `src/services/engine/frame/passes/orbitTrailsPass.ts:96-109` (modify),
+`src/data/bodies/orbitalElements.ts:1-9` (header, modify),
+`tests/services/engine/frame/passes/orbitTrailsPass.test.ts` (modify)
+
+**Before → after** (`orbitTrailsPass.ts:105-109`):
+
+```ts
+// before: centre = focus + centerOffset   (focus re-read, conic re-derived: a mirror of deriveBodyStates)
+// after:  centre = state.positionMpc − keplerianPositionMpc(propagated) + centerOffsetMpc
+```
+
+The body is now on its trail by construction: any later change to the snapshot position moves the
+trail with it. Keep `meanAnomalyRad` as the fade anchor, unchanged.
+
+- [ ] Add the test `trail follows a snapshot position that differs from raw Kepler`. Stub the states
+      map so one row's `positionMpc` is the Kepler position plus a 1e6 km vector (converted with
+      `SCALE_UNITS.KM_TO_MPC`). Read the packed eye-relative km basis (floats 34..45, written by
+      `eyeRelativeOrbitBasisKm`): the body point `C + A·cosE + B·sinE` at the row's propagated E must
+      equal the stubbed position, eye-relative in km, to ≤ 1 m. Use km tolerances throughout:
+      1e-15 Mpc is 30,000 km.
+- [ ] Run that test and confirm it fails against the current code.
+- [ ] Implement the after-line. Rewrite the `orbitalElements.ts` header sentence about "a body sitting
+      on its own trail is structural" so it names the snapshot anchoring.
+- [ ] The comparisons against `keplerianEllipse` (`orbitTrailsPass.test.ts:345-378`, `:511-573`) were
+      exact to 18–20 digits. Loosen them to `toBeCloseTo(…, 15)`, or the relative tolerance f64 can
+      hold for `(a + b) − b`, and give the reason in one line.
+- [ ] `npm test -- orbitTrailsPass`, then commit "Orbit trails anchor on the snapshot body position".
+
+### Task 2: Exact obliquity (P2)
+
+**Files:**
+- `src/data/bodies/orbitPlaneFrames.ts:72` (and the header comments at `:25`, `:29`, `:77-78`)
+- `src/utils/orbit/rotationLookAt.ts:19`
+- `src/data/defaults.ts:138-141`
+- `tests/data/bodies/orbitPlaneFrames.test.ts:50-53`
+- `tests/data/orientation/orientationFrames.test.ts:54`
+- `tests/utils/orbit/propagateElements.test.ts:94`
+- `tests/services/engine/frame/earthTerminator.test.ts:17`
+- `tests/fixtures/bodyStatesJ2000.json`
+- `tests/fixtures/camera/settleGoldenTrace.json`
+- `tests/fixtures/camera/driverGoldenTrace.json`
+- `tools/perf/perfScenarios.ts:52`
+
+Set `OBLIQUITY_DEG = 23.4392911` and say "IAU J2000 mean obliquity" in its comment. Comments that
+say `23.44°` become `23.439°`. Test literals use the exact value; in `orientationFrames.test.ts:54`,
+66.56° becomes `90 − 23.4392911`. No new test: this is a constant, and the existing frame tests pin it.
+
+- [ ] Change the constant, comments and test literals.
+- [ ] Regenerate `bodyStatesJ2000.json` with a one-off tsx snippet that is not committed. It
+      serialises `deriveBodyStates(2451545.0)` for every `ORBITAL_ELEMENTS` id in the fixture's
+      existing shape (`positionMpc`, `orientation`, `meanAnomalyRad`), leaves anchors out, and keeps
+      the key order. Diff it: only rotated values may change.
+- [ ] Re-record the camera traces with `SETTLE_GOLDEN_RECORD=1` and `DRIVER_GOLDEN_RECORD=1`
+      (`npm test -- settleGoldenTrace driverGoldenTrace`). The spec rules this. Then run once more
+      without the flags.
+- [ ] Update `EARTH_TARGET` in `perfScenarios.ts:52` to the new J2000 Earth position, taken from the
+      regenerated fixture.
+- [ ] `npm run typecheck:fast`, then `npm test -- orbitPlaneFrames orientationFrames propagateElements earthTerminator deriveBodyStates`.
+      Commit "Exact J2000 obliquity".

+## PR 2: feature (`accurate-planets`, stacked on prep)
+
+### Task 3: Correction type and evaluator
+
+**Files:**
+- `src/@types/scene/EphemerisCorrection.d.ts` (create)
+- `src/utils/orbit/ephemerisCorrectionMpc.ts` (create)
+- `tests/utils/orbit/ephemerisCorrectionMpc.test.ts` (create)
+
+**Interfaces, produced:**
+
+```ts
+export type EphemerisCorrection = {
+  startJd: number;
+  endJd: number; // fitted span (UTC JD); outside it the edge value is held
+  polyKm: readonly [Vec3, Vec3, Vec3, Vec3]; // coefficients of τ⁰..τ³, τ = 2(t − startJd)/(endJd − startJd) − 1
+  terms: readonly number[]; // flat, 7 per term: ω (rad/day), cos x,y,z (km), sin x,y,z (km); phase ω·(t − startJd)
+};
+export function ephemerisCorrectionMpc(c: EphemerisCorrection, simDays: number): Vec3;
+```
+
+Sum in f64 km, then multiply by `SCALE_UNITS.KM_TO_MPC`.
+
+- [ ] Test `evaluates polynomial and terms at a known instant`: a hand-built two-term correction,
+      checked against values worked out by hand.
+- [ ] Test `holds the edge value outside the span`: `simDays` 100 years before `startJd` returns
+      exactly (`toEqual`) the value at `startJd`, and likewise at `endJd`.
+- [ ] Test `is continuous across both span edges`: evaluations at edge ± 1e-6 day differ by < 1 m.
+- [ ] Implement, `npm test -- ephemerisCorrectionMpc`, then commit "Ephemeris correction evaluator".
+
+### Task 4: Horizons planet fetcher
+
+**Files:**
+- `tools/parsers/horizonsVectorsCsv.ts` (create)
+- `tests/tools/parsers/horizonsVectorsCsv.test.ts` (create)
+- `tools/fetch/fetchHorizonsPlanets.ts` (create)
+- `tools/utils/io/rawDataRegistry.ts` (add `horizons.planets` and `horizons.planets.readme`, using the
+  entry shape at `:17-25`)
+- `data/raw/horizons/planets/README.md` (create, committed; it records the exact query in Global
+  constraints)
+- `package.json` (add `"fetch-horizons-planets": "tsx tools/fetch/fetchHorizonsPlanets.ts"`)
+- `docs/DATA.md` (add a Horizons entry wherever the fetchers are listed)
+
+**Interfaces, produced:**
+
+```ts
+export type HorizonsVectorRow = { jd: number; xKm: number; yKm: number; zKm: number };
+export function parseHorizonsVectorsCsv(result: string): HorizonsVectorRow[]; // rows between $$SOE/$$EOE
+```
+
+The output goes to `data/raw/horizons/planets/<naif>.csv` with the columns `jd,x_km,y_km,z_km`,
+written through `rawDataPath('horizons.planets')`. Chunks are concatenated and a row whose `jd` is ≤
+the previous row's is dropped (Review focus 5).
+
+- [ ] Test `parses the SOE/EOE block of a Horizons vectors result`: use a trimmed real response
+      pasted as a string literal, three rows.
+- [ ] Test `concatenating two chunks drops the shared boundary row once`, through a small exported
+      merge step, or by asserting the fetcher's `mergeChunks` if you extract it. Keep it
+      one-symbol-per-file if extracted.
+- [ ] Implement the parser and the fetcher, which writes all eight CSVs. Announce the download size
+      before running it: 8 × ~3 MB.
+- [ ] Run `npm run fetch-horizons-planets`. Commit "Horizons planet fetcher", without the gitignored
+      CSVs.
+

+  startJd: number, endJd: number, stopKm: number, maxTerms: number): FitResult;
+export const PLANET_EPHEMERIS_CORRECTIONS: Readonly<Record<string, EphemerisCorrection>>; // keys: planet ids
+```
+
+**Method.** The spike is `planetSeriesFit.mts` in the brainstorm scratchpad; it measured ~590 terms.
+1. Fit the cubic in τ first.
+2. Then loop:
+   - take the FFT of the residual, zero-padded ×8, with power summed over x, y and z;
+   - find the peak and refine it parabolically;
+   - add a cos column and a sin column;
+   - Gram–Schmidt each new column against the kept ones, which makes it an exact least-squares refit;
+   - stop when the max 3D error is ≤ `stopKm`.
+3. Recover the coefficients of the original basis from the orthogonal one. Keep R, or refit by normal
+   equations once at the end, so the generated `terms` are plain (ω, cos, sin) amplitudes.
+4. The tool computes the residual as `Horizons − keplerianPositionMpc(propagateElements(row, jd))`.
+   It converts km with the same `MPC_TO_KM` the app uses, imports the `src/` modules directly, and
+   uses the app's own element rows.
+
+**Sample steps (days) for fitting:** Mercury 2, Venus 4, Earth 4, Mars 6, Jupiter through Neptune 10.
+The tool then **verifies on every 1-day row** with `ephemerisCorrectionMpc` (from Task 3) and throws
+if any planet exceeds 1,000 km. That way the shipped evaluator is exactly what gets verified.
+
+- [ ] Test `fft finds a pure sinusoid's bin`: N = 64, a sinusoid in bin 5, and the power peaks at k = 5.
+- [ ] Test `fitSinusoidSeries recovers a synthetic two-term signal`: a cubic plus two sinusoids at
+      non-bin frequencies. With `stopKm` 1, it should use ≤ 4 terms, and evaluating the result through
+      `ephemerisCorrectionMpc` reproduces the signal to ≤ 1 km.
+- [ ] Implement, then run `npm run build-planet-ephemeris`. Report each planet's term count and
+      verified max error; expect ~35–180 terms and a total of ~17 kB of numbers.
+- [ ] Commit "Planet ephemeris fit tool + generated corrections".
+
+### Task 6: Wire corrections and the Earth–Moon pair into `deriveBodyStates` · `review: yes`

+**Files:**
+- `src/@types/scene/BarycentricPair.d.ts` (create)
+- `src/data/bodies/barycentricPairs.ts` (create)

+export const BARYCENTRIC_PAIRS: readonly BarycentricPair[]; // [{ primaryId: 'earth', secondaryId: 'moon', secondaryMassFraction: 1 / 82.30057 }]
+```
+
+**1b loop, after this task:**
+`position = focus + kepler(el) + correction(el.id) − k · kepler(propagate(secondaryRow))`.
+- `correction` is `ephemerisCorrectionMpc(PLANET_EPHEMERIS_CORRECTIONS[el.id], simDays)` when a
+  correction exists, and zero otherwise.
+- The reflex term applies only when `el.id` is a pair's `primaryId`.
+- The secondary row comes from `ORBITAL_ELEMENTS` and is propagated inline, because `FOCUS_ORDER`
+  resolves `earth` before `moon`.
+- Resolve pair and correction lookups into id-keyed maps at module load, beside `FOCUS_ORDER`, never
+  per frame.
+
+**Fixture.** `tests/fixtures/horizonsPlanets.json` uses the Global constraints query, except with
+target `399` (Earth centre) for Earth.
+- Dates: 1900-06-01, 1979-03-05, 1980-11-12, 1986-01-24, 1989-08-25 and 2099-06-01 (Voyager flybys
+  plus both ends).
+- Shape: `{ [id]: { [jd]: [xKm, yKm, zKm] } }`.
+- The test header records the query URL.
+
+- [ ] Test `every planet is within 1,000 km of Horizons at the fixture dates`, from `deriveBodyStates`
+      positions. Earth is compared with Horizons `399` and gets its own tolerance: measure the max,
+      round up to the next 500 km, and write the measured number in a one-line comment, since it
+      includes the app Moon's error. This test is Review focus 4.
+- [ ] Test `Earth–Moon reflex keeps the barycentre and the separation`. At three dates, with
+      k = 1/82.30057, (1−k)·Earth + k·Moon equals the corrected EMB (Earth-row Kepler plus the
+      correction) to ≤ 1 m. Moon − Earth equals the Moon's raw Kepler offset to ≤ 1 m.
+- [ ] Test `an Earth surface site keeps its offset from the wobbling Earth` (Review focus 2): a site
+      hosted on `earth` minus Earth's position is independent of the reflex. Compare with the site
+      offset computed from `sitePointBodyFixed` and Earth's orientation.
+- [ ] Test `Moon, Hubble and Saturn sit on their trails at a non-J2000 date` (Review focus 3): drive
+      `orbitTrailsPass` packing at a 1989 date. Each body's position lies on its packed conic at its
+      propagated E, to ≤ 1 m, reading the eye-relative km basis as Task 1's test does.
+- [ ] Implement the pair table and the 1b term. Fix the `scenePlanets.ts:3` header.
+- [ ] Regenerate `bodyStatesJ2000.json` with Task 2's one-off snippet. Re-record the golden traces
+      with the record flags, then rerun without them. Update `EARTH_TARGET`.
+- [ ] Backlog: in the detail file, add that `BARYCENTRIC_PAIRS` exists, so Pluto's wobble is one row,
+      while the minor moons still need the invisible node. Update the BACKLOG line's clause to match.
+- [ ] `npm run typecheck:fast`, then `npm test -- planetEphemeris deriveBodyStates orbitTrailsPass`.

+# Accurate planet positions — design spec
+
+Child of the Voyager mission-trails brainstorm (2026-09-28 → 2026-10-03). Voyager's flybys
+are only as honest as the planets they pass: today's Keplerian planets drift from JPL by
+98k km at Jupiter up to 1.6M km at Saturn at the flyby dates, 9–16× the miss distances. On
+2026-10-03 the user ruled that **the accurate physical planet position is the source of
+truth**, independent of any flyby window, and that it ships as its own spec and PR before the
+mission-trails spec.
+
+## 1. What this is
+
+Heliocentric positions of the eight planets match JPL DE (Horizons) to **≤ 1,000 km over
+1900–2100**. That is 3% of the closest planet flyby (Voyager 2 at Neptune, ~29,000 km from
+centre). Four parts:
+
+- **A correction series per planet**, added on top of today's Keplerian position. It is a
+  cubic polynomial plus fitted sinusoids, generated offline from Horizons and shipped as
+  constants. All eight planets together take ~590 terms, about 17 kB. A build tool fits it
+  and checks it against JPL.
+- **Earth wobbles around the Earth–Moon barycentre (EMB).** The `earth` element row already
+  describes the EMB, so Earth = EMB − k·(Moon's geocentric offset), with k the Moon's share of
+  the pair's mass.
+- **Orbit trails follow the corrected body.** Each trail is the same Keplerian conic,
+  translated so it passes through the body's snapshot position.
+- **Exact obliquity.** `OBLIQUITY_DEG` becomes 23.4392911° instead of the rounded 23.44°.
+
+**Out of scope:**
+- Moon accuracy. Moons keep their own element rows.
+- Pluto–Charon. That becomes one more pair row later (§6).
+- Spacecraft. Mission trails is the next spec and reuses the fetch tool.
+- Any runtime TDB time scale.
+
+## 2. Ground preparation
+
+Refactor-ground ran on 2026-10-03. It sent an Explore trace over every reader of a planet's
+position and over the trail pass, and ran a greenfield cross-check. The user signed off on the
+checkpoint.
+
+| Touchpoint | Verdict | Seam |
+|---|---|---|
+| Body position (`deriveBodyStates.ts:63-67`) | growth | one added term in the 1b loop; it is the only place positions are composed |
+| Orbit trail (`orbitTrailsPass.ts:101-109`) | **bolt-on → P1** | the pass re-propagates each conic and re-folds the focus itself, a mirror of `deriveBodyStates`. The body sits on its trail only because both happen to agree, so adding the correction here would make a second copy |
+| Obliquity (`orbitPlaneFrames.ts:72`) | **wrong constant → P2** | the fit is generated against the app's frame, so the constant must be right before the first generation |
+| Earth wobble | growth | a new pair table read in the same 1b loop. No focus-graph node: the backlog's invisible-node design is needed only for Pluto's minor moons |
+| Synchronous readers at module load (`bodyRegions.ts:29`, `starCatalog/create.ts:63`) | growth | the generated `.ts` is a static import, as with `bodyFacts.generated.ts` |
+| Generated data | growth | `tools/bodies/buildPlanetFacts.ts` precedent: banner, prettier, committed output |
+
+**The greenfield cross-check diverged on three points, all resolved by measurement or ruling:**
+- **Residual table → fitted series.** A table needs ~140 kB in f32 (Mercury needs a 13-day
+  step); the series needs ~17 kB.
+- **Sampled trail with a geometric tail → translated conic.** With a translated conic the
+  worst case is Saturn: 4 px with the whole orbit 1,000 px wide, and 0.34° tangent error close
+  up. Mercury through Earth stay under 0.1 px.
+- **Spacecraft in planet-relative legs → rejected.** With accurate planets, heliocentric
+  samples are enough. That decision belongs to the mission-trails spec.
+
+**Prep, as a separate PR (ruled 2026-10-04):**
+
+- **P1: trails anchor on the snapshot body.** `orbitTrailsPass` takes
+  `centreMpc = state.positionMpc − keplerianPositionMpc(propagated) + centerOffsetMpc` instead
+  of `focus + centerOffsetMpc`.
+  - This is behaviour-neutral today, apart from f64 rounding.
+  - Once this lands, the body sits on its own trail by construction rather than by coincidence.
+  - Any later change to a body's position (correction, pair reflex, a moon's parent) moves the
+    trail with it.
+  - The 18–20-digit trail tests (`orbitTrailsPass.test.ts:345-378`, `:511-573`) move to a
+    tolerance that f64 can actually hold.
+  - The `orbitalElements.ts` header line about the invariant is rewritten to name the new
+    mechanism.
+- **P2: exact obliquity.** `OBLIQUITY_DEG = 23.4392911` (IAU 1980 / J2000 mean obliquity).
+  - The obliquity literals in tests follow: `orbitPlaneFrames.test.ts:53`,
+    `orientationFrames.test.ts:54`, and the comments in `propagateElements.test.ts:94` and
+    `earthTerminator.test.ts:17`. So do the `23.44°` comments in `rotationLookAt.ts` and
+    `defaults.ts`.
+  - The fixture `tests/fixtures/bodyStatesJ2000.json` and the camera golden traces are
+    re-recorded, under this ruling, with `SETTLE_GOLDEN_RECORD=1` and `DRIVER_GOLDEN_RECORD=1`.
+
+## 3. Data shapes
+
+```ts
+// src/@types/scene/EphemerisCorrection.d.ts — one planet's DE − Kepler correction, km
+export type EphemerisCorrection = {
+  startJd: number; endJd: number;     // fitted span; outside it the edge value is held
+  polyKm: readonly [Vec3, Vec3, Vec3, Vec3]; // cubic in τ = 2(t−start)/(end−start) − 1
+  // flat (ω rad/day, cos x,y,z, sin x,y,z) per term; phase measured from startJd
+  terms: readonly number[];
+};
+
+// src/@types/scene/BarycentricPair.d.ts — the primary's element row describes the pair barycentre
+export type BarycentricPair = { primaryId: string; secondaryId: string; secondaryMassFraction: number };
+
+// src/data/bodies/planetEphemerisCorrections.generated.ts   (GENERATED — DO NOT EDIT)
+export const PLANET_EPHEMERIS_CORRECTIONS: Readonly<Record<string, EphemerisCorrection>>;
+
+// src/data/bodies/barycentricPairs.ts
+export const BARYCENTRIC_PAIRS: readonly BarycentricPair[] =
+  [{ primaryId: 'earth', secondaryId: 'moon', secondaryMassFraction: 1 / 82.30057 }];
+```
+
+**Frame and time are pinned by construction, not converted at runtime.**
+- **Frame.** The fit tool computes `DE − app Kepler` in the app's own equatorial frame, so any
+  residual frame bias is absorbed into the correction.
+- **Time.** Horizons is fetched with `TIME_TYPE='UT'`, which is verified to be accepted for
+  vector tables, so the TDB−UTC gap (~69 s, ~2,000 km at Earth) is absorbed as well. `simDays`
+  stays a UTC Julian date.
+- **Planet targets.** Mercury and Venus use their planet centres (199, 299). Earth through
+  Neptune use their system barycentres (3–8), because the planet-centre wobble caused by moons
+  is ≤ 300 km.
+
+## 4. Runtime
+
+- **`src/utils/orbit/ephemerisCorrectionMpc.ts`** —
+  `(c: EphemerisCorrection, simDays: number) => Vec3`. It clamps `simDays` to
+  `[startJd, endJd]` (the ruled freeze-at-edge), sums the polynomial and the terms in f64 km,
+  then converts to Mpc. The conversion happens before the sum joins an au-scale position, as in
+  the site-offset precedent at `deriveBodyStates.ts:88-94`.
+- **`deriveBodyStates` 1b:**
+  `position = focus + kepler(el) + correction(el.id) − pairReflex(el.id)`.
+  - `pairReflex` is `secondaryMassFraction · keplerianPositionMpc(propagateElements(secondary))`
+    for a primary listed in `BARYCENTRIC_PAIRS`.
+  - The secondary's offset is computed inline, because `FOCUS_ORDER` resolves `earth` before
+    `moon`.
+  - Dependants of `earth` (the Moon, Hubble, the easter eggs, Earth sites) follow the
+    reflexed Earth automatically. So Moon = EMB + (1−k)·geo, which is physically right.
+- **Cost:** about 590 sinusoid evaluations per new `simDays`, a few µs. The existing one-deep
+  memo makes paused frames free. Trails add nothing, because P1 reads the snapshot.
+
+## 5. Tools
+
+- **`tools/fetch/fetchHorizonsPlanets.ts`** (`npm run fetch-horizons-planets`).
+  - Fetches 1-day equatorial heliocentric vectors, 1900–2100, in 50-year chunks with retry.
+  - Writes them to `data/raw/horizons/planets/<naif>.csv`.
+  - The output is gitignored, registered in `rawDataRegistry.ts` with a README next to it
+    that records the exact API query.
+- **`tools/bodies/buildPlanetEphemeris.ts`** (`npm run build-planet-ephemeris`).
+  - Subtracts the app's Kepler position using the `src/` propagation, imported as
+    `buildPlanetFacts` imports `src` types.
+  - Fits each planet greedily: cubic polynomial, then sinusoids. Each frequency is the
+    zero-padded FFT peak of the remaining residual, and a Gram–Schmidt step refits all
+    coefficients exactly by least squares.
+  - Stops once a planet is ≤ 900 km, leaving margin.
+  - **Verifies every planet on the dense 1-day grid** and throws above 1,000 km.
+  - Writes the generated file with a banner plus prettier.
+  - Helpers go one function per file under `tools/utils/math/` (`fft.ts`,
+    `fitSinusoidSeries.ts`).
+- **Regeneration rule:** any edit to a planet's element row or to the frame requires
+  re-running the build tool. The test in §7 fails until it is re-run.
+
+## 6. Docs and backlog
+
+- `scenePlanets.ts:3`: rewrite the stale "positions via keplerianPositionMpc" header.
+- `docs/backlog/2026-08-16-barycentric-orbit-pairs.md`: note that the pair table now exists.
+  Pluto's wobble becomes one `BARYCENTRIC_PAIRS` row; the minor moons still need the invisible
+  node. The BACKLOG line stays and its clause is updated.
+- `docs/DATA.md`: add a Horizons fetch entry.
+- `orbitReachByRegion` gets no margin for the correction. ≤ 8M km is negligible against
+  Pluto's ~50 au reach. Recorded here, not backlogged.
+
+## 7. Tests
+
+- **`tests/data/bodies/planetEphemeris.test.ts`.**
+  - Fixture: a committed Horizons fixture, `tests/fixtures/horizonsPlanets.json`, with 6 dates
+    × 8 planets, UT, equatorial.
+  - `deriveBodyStates` must be ≤ 1,000 km from each fixture vector.
+  - It fails if anyone edits a planet's elements or the frame without regenerating.
+  - Earth is checked against Horizons 399 (Earth centre) to ≤ 1,000 km plus the Moon-model
+    error. The tolerance is stated in the test after measurement.
+- **`ephemerisCorrectionMpc.test.ts`:** a clamped date returns exactly the edge value
+  (freeze), with continuity across `startJd` and `endJd`.
+- **Pair reflex:**
+  - Earth–Moon distance is unchanged.
+  - The EMB, computed as (1−k)·Earth + k·Moon, equals the old Earth position.
+- **Re-recorded:**
+  - `tests/fixtures/bodyStatesJ2000.json`
+  - the camera golden traces
+  - `tools/perf/perfScenarios.ts:52` `EARTH_TARGET`
+  - the 2024-04-08 eclipse test keeps its 2° tolerance, and should tighten.
+
+## 8. PR sequence
+
+1. **Prep PR** (separate, ruled): P1 and P2, each its own commit. They are behaviour-neutral
+   except for the obliquity.
+2. **Feature PR**, built on top of it:
+   - fetch tool and raw-registry entry
+   - fit tool and helpers
+   - generated corrections
+   - pair table and the `deriveBodyStates` term
+   - tests, docs and backlog edits

 Earth's whole-globe base texture and its surface tile pyramid are two publications of one Blue Marble month (a 21600×10800 equirect and eight 21600×21600 quadrants, ~421 MB). The month is chosen once in [`bmngVintage.ts`](../tools/utils/io/bmngVintage.ts) and every registry path, upstream URL, and attribution string reads it from there. The tile layer falls back to the base outside its baked window, so a vintage split between the two would draw a visible seasonal seam along the tile frontier.
 
+### Planet positions (JPL Horizons)
+
+Each planet's position is its Keplerian row plus a fitted correction series that matches JPL DE to ≤ 1,000 km over 1900–2100. `npm run fetch-horizons-planets` pulls 1-day heliocentric ICRF vectors (8 × ~3 MB, gitignored) into `data/raw/horizons/planets/`, and `npm run build-planet-ephemeris` fits them into the committed `src/data/bodies/planetEphemerisCorrections.generated.ts`. Regenerate after any planet element-row or frame change. The exact query is in [`data/raw/horizons/planets/README.md`](../data/raw/horizons/planets/README.md).

 ### Earth surface tile pyramid
 
 The bake emits `public/data/images/earth-tiles/v10/albedo/<z>/<x>/<y>.webp`: 512 px lossy WebP tiles whose alpha channel doubles as the land mask, plus two sidecars, `index.txt` (one path per line) and `manifest.json` (the flat band list every product's planner filters by `builtFrom`). `npm run build-surface-tiles` is idempotent per tile (a tile whose output already exists is skipped, byte-identical, on a re-run) and refuses to write `index.txt`/`manifest.json` at all if any tile the prior index promised is missing on disk, leaving both untouched — an interrupted or partially-deleted bake never advances the pointer to half-baked data ([`buildSurfaceTiles.ts`](../tools/textures/buildSurfaceTiles.ts)).

 The focus graph is strictly one-hop: `OrbitalElements.focusId` makes a body orbit its parent's *center* (`src/services/engine/frame/deriveBodyStates.ts` resolves positions along `focusResolveOrder`). Real binary-ish systems orbit a shared barycentre:
 
-- **Pluto–Charon**: Charon is ~12% of Pluto's mass; the barycentre sits ~2,130 km from Pluto's centre — 1.8 Pluto radii, i.e. ~940 km *above* the surface. The shipped model (Charon as a Moon-style satellite of Pluto) pins Pluto at its heliocentric position — an error of ~10% of the pair separation, visible only when parked near the barycentre with time running. The same approximation already applies to Earth–Moon (Earth doesn't wobble around the EMB), just less visibly.
+- **Pluto–Charon**: Charon is ~12% of Pluto's mass; the barycentre sits ~2,130 km from Pluto's centre — 1.8 Pluto radii, i.e. ~940 km *above* the surface. The shipped model (Charon as a Moon-style satellite of Pluto) pins Pluto at its heliocentric position — an error of ~10% of the pair separation, visible only when parked near the barycentre with time running. Earth–Moon no longer has this error: see the pair table below.
 - **Pluto's minor moons** — Styx, Nix, Kerberos, Hydra — orbit the *barycentre*, not Pluto, at wider radii where the approximation grows proportionally worse. They are deliberately absent until this lands (grill Q5): four sub-pixel irregular rocks drawn dishonestly around Pluto's center add clutter without honesty.
 
-## Shape of a fix
+## What exists now
+
+`BARYCENTRIC_PAIRS` (`src/data/bodies/barycentricPairs.ts`) treats a primary's element row as the pair barycentre, and `deriveBodyStates` subtracts the secondary's mass-weighted reflex from the primary. Earth–Moon is its one row. Pluto's wobble is therefore one more row (`pluto`/`charon`, Charon's mass fraction ≈ 0.1086), once Pluto's row is re-fitted to the Pluto-system barycentre. The minor moons still need the invisible node below, because they orbit the barycentre rather than either body.
+
+## Shape of a fix (minor moons)
 
 An invisible barycentre node in the focus graph that both partners orbit. Touchpoints that currently assume focus-graph nodes are visible bodies: pick tables (`resolvePickTable.ts` maps source → seed table by index), region extents (`bodyRegions.ts` maxes over members), labels/captions (every `SCENE_PLANETS` row gets one), glint partition. Either a `visible: false` body kind or a separate node table that only `deriveBodyStates` sees.
 
 ## Follow-on once landed
 
-- Let Pluto (and optionally Earth) wobble: re-parent Pluto → `pluto-barycentre` with a ~2,130 km semi-major element row; delete the "looks wrong, don't fix" comment on Charon's row.
+- Let Pluto wobble: add the `pluto`/`charon` row to `BARYCENTRIC_PAIRS`; delete the "looks wrong, don't fix" comment on Charon's row.
 - Add Styx/Nix/Kerberos/Hydra as ordinary satellite rows parented on the barycentre node (no textures — no usable maps exist; flat albedo + glint only).

+Dispatch A (Tasks 1–2, Sonnet) launched on accurate-planets-prep; draft PR #834; base c798ac56a
+Task 1: complete (commits c798ac56a..2183ed6b7, final review pending)
+Task 2: complete (commits 2183ed6b7..7edf35cb5, final review pending)
+Ruling: Task 1 on-trail tolerance 0.1 km, not 1 m — the eye-relative basis is packed f32 (~30 m step at the Moon's 4e5 km); injected offset 1e6 km is 4 orders above — costs: a sub-100 m anchoring regression would pass. Same tolerance for Task 6's on-trail test.
+Ruling: 18–20-digit keplerianEllipse comparisons left unloosened — they still pass, loosening would be churn — costs nothing.
+Golden traces checked: same structure (26/26, 47 entries), only J2000 Earth coordinates rotated by the obliquity fix.
+Prep pushed 7edf35cb5; CI watch on #834; final review (Opus) dispatched. Feature branch accurate-planets created at 7edf35cb5; Dispatch B (Tasks 3–5, Opus) launched.
+Prep final review: 3 Minor (propagateElements.test.ts:93-94 garbled comment; orbitalElements.ts:4 header not re-wrapped; settleGoldenTrace.json minified by re-record). No Critical/Important.
+Ruling: controller fixes the 3 Minors inline on accurate-planets-prep (<50 lines, lean protocol) AFTER Dispatch B finishes (worktree is on accurate-planets), then merges prep into accurate-planets — avoids switching branches under a live agent — costs: prep PR waits ~1 dispatch.
+Prep CI RED (1/1426): cameraFraming.test.ts:76 GALACTIC_DISC_FORWARD decodes to yaw −1.4208018 vs −1.4208 @1e-6 — the exact-obliquity ecliptic frame shifts the decode ~2e-6 rad.
+Ruling: relax yaw/pitch to toBeCloseTo(…, 4) with a one-line why (still catches a mistyped 4th decimal, 1e-4 > 5e-5); do NOT re-derive GALACTIC_DISC_FORWARD (a 1e-5 rad view change nobody sees) — costs: the pin is 50× looser. Folded into the controller's prep fix commit after Dispatch B.
+Prep fix commit 309d53be8 (3 review Minors + cameraFraming 4-place ruling; settle recorder now writes 2-space JSON and trace re-recorded) pushed; CI re-watch running.
+Task 3: complete (commits 7edf35cb5..428f92fdc, final review pending)
+Task 4: complete (commits 428f92fdc..e79ff43f2, final review pending)
+Task 5: complete (commits e79ff43f2..2f0c8f0d3, final review pending) — 525 terms, max verified 900 km (Earth), 36.2 kB text
+Ruling (Dispatch B deviations accepted): golden-section frequency refine instead of parabolic (2 vs 21 terms on two-tone test); fit grid always includes the final row (Uranus failed 1,012 km at 2100 otherwise); generated file 36 kB text not ~17 kB (plan assumed f32 binary; text with 12-digit ω is the honest size) — costs: bundle +36 kB raw (~less gzipped).
+Prep merged into accurate-planets (948758534); feature draft PR #835 (base accurate-planets-prep). Dispatch C (Task 6, Opus) launched.
+Prep PR #834 CI GREEN at 309d53be8; review clean after fixes → ready for user smoke/merge ruling.
+Task 6: complete (commits 948758534..b707c020b, final review pending) — vs Horizons fixture: Me 593, V 616, E 621 (vs 399), Ma 868, J 307, S 333, U 279, N 300 km; k=0 mutation → Earth 4,830 km, reflex test fails.
+Ruling (accepted): BARYCENTRIC_REFLEX_BY_PRIMARY as 2nd export of data/bodies/barycentricPairs.ts (frameFilePurity bans the module-level map in deriveBodyStates) — costs: data file with two exports. Saturn on-trail check at 1 m on the f64 conic (packed f32 step 128 km at Saturn); Moon/Hubble 0.1 km on packed basis. HorizonsSeries type moved to tools/bodies/@types (noInlineTypes).
+Feature final review: clean of Critical/Important; 6 Minors (unused maxErrKm; BARYCENTRIC_PAIRS export unused + test restates k; inline dot helper; golden-section double eval; lo=0 NaN probe; parser throw-case test). Ruling: fix all 6 in ONE fix dispatch after local CI finishes (stacked PR gets no GitHub CI — base ≠ main; local typecheck+lint+test run as the gate).
+Local CI on b707c020b: typecheck+lint+test GREEN (1432 files / 14950 tests). Fix dispatch (6 Minors, Sonnet) launched.
+Fix dispatch 8eea5fe69: 6 Minors fixed; fixer reverted the regenerated file (1e-10 rounding noise broke exact fixtures).
+Ruling: controller regenerated corrections from the final tool + re-blessed bodyStatesJ2000 and both golden traces (60a10eec9) so the committed generated file equals tool output — costs: fixture churn of rounding noise only (same term counts, same max errors).
+Local CI on 60a10eec9: 1429/1429 files, 14943 tests pass; 3 worker-start timeouts (load) re-run green (3 files, 7 tests). Both PRs review-clean. NEXT: user smoke (plan DoD) → /feature-done → merge on user's word (prep #834 first, then retarget #835 to main).
+
+## /feature-done IN PROGRESS (2026-10-04) — user smoke PASSED ("looks good")
+DoD findings so far: tests+typecheck GREEN (local full run on 60a10eec9, no change since); checkboxes 0/31 ticked (tick all on READY); DoD section PRESENT; spec Ground preparation PRESENT; unexpected files (all explained): earthUniverseLoop.test.ts, settleGoldenTrace.test.ts (recorder), mergeHorizonsChunks(.test).ts, tools/@types/math/FitResult.d.ts, tools/bodies/@types/HorizonsSeries.d.ts, tools/parsers/@types/HorizonsVectorRow.d.ts, tools/utils/math/dot.ts; untouched planned: none; new TODOs: 0; comment density OK; test parity grew; smoke FOUND; deferred = plan "Out of scope" list (moons, Pluto pair row → backlog detail updated, Voyager → mission-trails spec next, runtime TDB, orbitReachByRegion margin).
+IN-FLIGHT: deletion-audit agent (opus, GREENFIELD/--justify, read-only) → report at scratchpad `deletion-audit-accurate-planets.md`. ON RESULT: apply SAFE-NOW bin as its own deletion commit on `accurate-planets` (dispatch Sonnet if >2 files), run targeted tests, push; NEEDS-RULING items → ask user. Then READY → tick plan checkboxes; git mv plan → plans/completed/, spec → specs/completed/; copy this ledger → plans/completed/2026-10-04-accurate-planet-positions.ledger.md; backlog sweep (barycentric-pairs item STAYS, only its clause was updated); commit "docs(plan): mark accurate-planet-positions complete" (NO Co-Authored-By per user memory); push accurate-planets.
+THEN: merge ONLY on user's "merge this PR": #834 first (squash), then retarget #835 base → main, rebase/merge main, GitHub CI, merge. After both land: Voyager mission-trails spec (memory project_mission_trails.md).
+Dev server for this wt: localhost:5176 (bg, started this session) — leave running.
+Deletion audit done (report: scratchpad deletion-audit-accurate-planets.md): safe-now ~27 LOC (FitResult.d.ts, import guard, keplerKm reuse, edge-continuity test, HorizonsSeries.d.ts) → Sonnet dispatch applying. NEEDS-RULING asked as dash ask 4UUQ (site test keep(rec) · real-data on-trail test delete(rec) · pair table keep(rec) · mergeHorizonsChunks keep(rec)).
+Safe-now deletion commit 788c5f627 pushed (typecheck both tsconfigs + tests/tools tests/utils/orbit green). Waiting on ask 4UUQ.
