Based on main after #743 merge (cst_prod_tag). Rebased the geodesic letter off the stacked cursor/sqlmm-tau-mu-kinks-62c0 tip onto origin/main. New claimId 0007-intake-geodesic. Does not remint 0007-sqlmm-signed-tag or 0007-intake-walker. Does not touch #729, SheetHenCook.v, or SidecarGeodesicEgg.v cook story.

This letter changes μ, not another map of names. A well-formed GeodesicString tagged CST becomes an SHC bag of MkChord on sheet (S), the same bag family as LineString.

μ (IntakeWalker.v).

τ row (SqlMmSignedTag.v, no new ticket zoo).

  • No TagGeodesic. HOLD 13 stays a nat. κ does not gain 13 (kappa_not_13).
  • tau_mu_locked_geodesic: μ bags [MkChord], first_slice_tag e = Some TagLineString, cst_prod_tag locked_geodesic_cst = None.
  • Circle/CS pattern with the other interpolant: two productions, one egg class.

Qed.

  1. intake_map default_sheet locked_geodesic_cst = IntakeBag _
  2. bag_eggs / chickens are MkChord only
  3. Same bag as LineString for the same points
  4. first_slice_tag is Some TagLineString
  5. TSpiralCurve still Declines

QEX (named). Ellipsoid geodesic γ; WKB 13 as signed I/O; emit of GEODESICSTRING bytes; τ=π on the geodesic production.

Not this letter: first-cook expand, emit / JTS #7 / tools/ visitor (still Declines GEODESICSTRING — next repo rung), oracle keyword, park ρ / ι / CircGamma.

This PR was drafted with AI assistance. Rebase onto main was also AI-assisted.

…sic)

Change μ, not another map of names. Well-formed TGeodesicString pts
returns IntakeBag (map_ls S pts) — same hens and MkChord chickens as
LineString. ID_GeodesicString is not the well-formed answer. Spiral
still Declines. One signed-tag agreement row: τ is LINESTRING,
cst_prod_tag stays None. No TagGeodesic; κ does not gain 13.

Breaking: TGeodesicString now carries list Point (was a unit ctor).

Well-formed GEODESICSTRING is 0007-intake-geodesic. Do not remint
0007-intake-walker.

Compress the geodesic letter so μ stays in this file without
crossing the monolith threshold.

μ(S, TGeodesicString pts) = μ(S, TLineString pts). Eggs are MkChord
only. γ_ch joints, τ=LINESTRING, π(G)=GEODESICSTRING ∉ T_signed.
Consecutive eggs already first_cook_scope. Companion IntakeGeodesic.v
keeps IntakeWalker under the module-split gate.

Empty commit so GitHub Actions sees a synchronize event now that
the pull request base is main (workflows only run for PRs targeting
main). Rebase itself was already force-pushed at 995ee9c.
