What this PR does

Removes 44 NEON-mirror markdown files from docs/golden-sunflowers/ and rewrites the README so the SSOT principle is unambiguous:

• 34 × ch-*.md deleted (all marked auto-generated from ssot.chapters.body_md in the v4 README).
• 10 × app-*.md deleted (App.A through App.J).
• README.md rewritten — explicit: NEON is canonical, the build pipeline reads NEON, no per-chapter markdown should ever be committed here.
• pdf/ directory kept (rendered artefacts).

What this PR does NOT do

• Does not touch NEON ssot.chapters or ssot.one_shots data (one-source rule — repo PRs only adjust the build pipeline, never the canonical content).
• Does not modify docs/phd/chapters/*.tex (37 files). These are the original LaTeX lanes from 🎯 ONE SHOT — PhD «Flos Aureus»: Autonomous Development at Top Scientific Standards #265 (R1–R14, claim-before-work, lane discipline). They predate the NEON pivot and are still referenced by docs/phd/main.tex \include{chapters/…} lines and by assertions/witness/citetheorem_audit.toml. A second PR will migrate those into NEON once the lane owners confirm content parity.
• Does not delete crates/trios-phd, migrations/005_hero_fullwidth.sql, templates/chapter.template.tex, filters/force-fullwidth-hero.lua, or the cold-feather phd_build_v5/ workspace skill — these are the build pipeline, the legitimate consumer of NEON.

R-rules compliance (R5 honest)

• R5 honest single-source. All 44 deleted files were explicitly self-marked as NEON mirrors in the v4 README.md. Their removal cannot drop content, because ssot.chapters.body_md is the canonical store and the build pipeline reads from there directly.
• R6 lane discipline. Single-purpose PR: only docs/golden-sunflowers/ files are touched.
• R10 atomic commit. One commit, one logical unit (mirror removal + README rewrite as a paired action — semantic atomicity preferred to per-file commits because the unit of meaning is "drop the mirror").
• Queen-silence policy. No gHashTag/trios#372 / #373 / #265 posts attached to this PR. The user explicitly requested the cleanup; no further trigger needed for the PR body itself, but there will be no auto-posts to the SSOT issues.

Withdrawn predecessor

• PR feat(golden-sunflowers): FA.10 Golden Bloom — phyllotaxis, φ-divergence, parastichy, Voronoi (~55k chars, 12 theorems) #510 (FA.10 Golden Bloom markdown duplicate) — closed without merge for the same reason. The FA.10 chapter content remains canonical in ssot.chapters.body_md (length=55,232, theorems_count=12, status=done, completed_at=2026-05-05 16:22:45 UTC).
• Branch feat/golden-sunflowers deleted (no longer the canonical authoring channel).

Verification (post-merge)

After merge, the following must still hold:

git ls-files docs/golden-sunflowers/ | grep -E '^docs/golden-sunflowers/(ch|app)-' | wc -l
# expected: 0

git ls-files docs/golden-sunflowers/ | sort
# expected:
#   docs/golden-sunflowers/README.md
#   docs/golden-sunflowers/pdf/...

# NEON canonical store unchanged:
psql "$DB" -c "SELECT COUNT(*) FROM ssot.chapters;"
# expected: 98 (unchanged)

# Pipeline still consumes NEON:
cargo run -p trios-phd -- compile-chapters
# expected: 98 chapters compiled, exit 0

Anchor

φ² + φ⁻² = 3 — Trinity identity unchanged.
