plan: epiphany-integration v3 (ratified) — membranes, parity, unified ruff phases#646
Conversation
…matrix Review for future sessions on when each orientation codec is right, born from the q2 /helix session where the two were repeatedly confused. - ndarray helix_orient (Cartesian pseudo-helix): golden-spiral cap cascade, value IS the reconstructed vector, place-blind, no metric — use when you materialize the vector ONCE and need no distance/HHTL coupling. - lance-graph helix::Signed360 (Fisher-2z normalized): place-coupled, metric-safe 256x256 L1 DistanceLut, value is that you NEVER reconstruct — use for O(1) orientation distance, residue-on-HHTL search, large-N rendering (pre-materialize a LUT once, gather per element; no per-vertex atanh/trig). Decision rule: count materializations. Reconstructing a normalized representation per element is always the wrong move. Plus Signed360 specifics (sign turns hemisphere into full sphere; rim is the metric/atanh carrier, never materialized for rendering; direction is place-independent). Adds .claude/knowledge/helix-cartesian-vs-fisher2z.md (READ BY header) and prepends E-HELIX-NEVER-MATERIALIZE to the EPIPHANIES board.
… ruff phases The full operator-directed review pipeline, complete: Fable-5 draft -> 5x Sonnet PR-history drift audit (lance-graph #618-#645, OGAR #139-#151, ruff #33-#41, ndarray ruled out) -> 5x Opus savant review (iron-rule, dto-soa, prior-art, cascade-impact, creative-explorer) -> 3x Opus brutal review (overclaim RESTATE-10, dilution REPAIR-3, baton CATCH-CRITICAL-1) -> all findings folded into the ratified text. Registry: 2 new parent laws (E-BOUNDARY-FUSE-1, E-REGISTRY-COMPLETENESS-ORACLE-1) + 14 instance rows, all PENDING the epiphany-brainstorm-council (deliverable B1); 9 OVERLAPS rows carry mandatory cross-refs, 2 rows file at CONJECTURE. Includes the self-caught E-PLAN-GROUND-STATE-IS-A-RANGE-1 (ruff main moved #39->#41 mid-draft; cite the executable, never the prose). Deliverables: unified ruff phase sequence (A1 mints a NEW branch per BH-4 -- never re-point the shared branch name; A2a freeze at derived count 62; A4 rescoped as a feature; A7 blocked on Q-A7 after BH-5's meta-membrane finding), council filing + V3-folder drafts with 7-day fallback, OGAR doctrine bullets, and consumer-side baton homes (the ruff board file carries the plan pointer + gate markers). Board hygiene in same commit: INTEGRATION_PLANS.md prepend + STATUS_BOARD.md D-EPI-* rows. Doc-only; execution queued behind D1->A1.

Next review available in: 2 minutes Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

There was a problem hiding this comment.
For consumers using this new mandatory knowledge note to decode or compare Signed360, this statement is off by one layer: place % 17 is only CurveRuler::start_offset(); the serialized rim.start_idx is floor.quantize(ResidueEncoder::aligned_for_place(place)) (crates/helix/src/residue.rs:155-168), so it is a rolling-floor 0–255 bucket. If a renderer/search tool treats that byte as the raw modulo-17 HHTL anchor, it will build the wrong lookup/distance key for most places/floor versions.
