board: E-OCR-LINEFINDER-1 — 3F₂ complete (Green's-theorem shortcut + two documented boundaries)

[AdaWorldAPI]

Append-only EPIPHANIES entry for 3F₂ (companion: the tesseract-rs line-finder PR).

E-OCR-LINEFINDER-1 — the real makerow line finder replaces the projection approximation. Carries the three transferable findings: (1) the Green's-theorem shortcut — enclosed_area nets to the CC ink pixel count, so the seedfill counts during the fill and the ~1000-line edge-tracer port evaporates; (2) the float floor precision finding (min_y = floor(initial_x/2) stays pure f32 while sibling expressions promote to f64); (3) the two honestly documented composition boundaries — blob source (pixConnComp vs edge-traced) and line feeding (raw expanded bands vs baseline-normalized linerec.cpp images, with expand_rows's faithful ~0.75/0.25 baseline asymmetry explaining band-height variance).

Docs only — code + oracles live in tesseract-rs.

📝 Walkthrough

Walkthrough

Updates the top of .claude/board/EPIPHANIES.md, replacing the prior wave-3 x-height-chain entry with a new "E-OCR-LINEFINDER-1" epiphany documenting the makerow line finder implementation, byte-parity findings, pipeline wiring, and outstanding boundaries.

Changes

EPIPHANIES.md update

Layer / File(s)	Summary
Line finder epiphany entry .claude/board/EPIPHANIES.md	Replaces the previous epiphany header and status with a new entry describing connected-component area computation, filter_noise_blobs byte-parity, recognize_page_makerow pipeline wiring, and updated concluding notes.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Poem

A rabbit hops through notes so neat,
Line finders found, the parity complete.
🐇✨ Pixels counted, holes subtracted,
Boundaries noted, epiphanies redacted.
Onward to the next hop's beat!
