Summary

Follow-up to merged #244 (branch restarted from master). Records the operator-proposed forward synthesis in the §10 honesty-ledger area of the matrix doc, graded and probe-gated:

  • [H] One Walsh–Hadamard family for BOTH pyramid sides. OGAR canon already frames the bipolar-phase pyramid's sign side as the WH transform of the address tree; bgz-tensor's proven hadamard_rotate is the same transform family on the stored-magnitude side (the standard outlier-flattening/incoherence preconditioner before cheap uniform quantization). Proposal: WHT₁₆ on a 4×4 tile's 16-cell magnitude vector before nibble quantization — the two-algebra rule is untouched (the rotation is a coding-side preconditioner, not a merge mode). PROBE-WH-MAG named: WHT₁₆+i4/i2 vs direct i4/i2 on real tile magnitudes — bgz-tensor's row-level win does not automatically transfer to 16-cell tiles.
  • [S] Hambly–Lyons signature as the replayable-trajectory checksum. The §7 x264 contrast asked for a replayable, checksummable stream; the signature is the canonical path digest with a uniqueness theorem, and tree-like equivalence is the digest's exact null space — the formal version of "which detours leave no comma." Both harnesses already exist (jc Pillar 11 forward/converse; this repo's pillar/signature.rs B7). PROBE-SIG-CHECKSUM named on those harnesses.

Neither proposal adds a stored field to the tile. Both stay conditional on the standing §10 ledger; no kill condition touched. Blackboard entry appended. Twin board entry: lance-graph E-WH-TWO-SIDES-SIG-CHECKSUM-1.

Verification

  • Knowledge-doc test suite: 117/117 green.
  • Grounding checked against source/canon: OGAR CLAUDE.md "Bipolar-phase pyramid — Walsh-Hadamard on VSA", bgz-tensor/src/adaptive_codec.rs::hadamard_rotate, jc/src/hambly_lyons.rs, src/hpc/pillar/signature.rs.

…signature as trajectory checksum (probe-gated)

Follow-up to merged #244 (branch restarted from master). Two candidate
adoptions for the Morton-tile stacked inverse pyramid, operator-proposed,
recorded [H]/[S] with named probes:

- [H] One Walsh-Hadamard family for BOTH pyramid sides: OGAR canon
  already frames the bipolar-phase pyramid's sign side as the WH
  transform of the address tree; bgz-tensor's proven hadamard_rotate is
  the same family on the stored-magnitude side (outlier-flattening
  preconditioner before cheap uniform quantization). Proposal: WHT16 on
  a 4x4 tile's magnitude vector before nibble quantization; two-algebra
  rule untouched (the rotation is a coding-side preconditioner, not a
  merge mode). PROBE-WH-MAG: WHT16+i4/i2 vs direct i4/i2 on real tile
  magnitudes — the row-level win does not automatically transfer.
- [S] Hambly-Lyons signature as the replayable-trajectory checksum:
  tree-like equivalence = the digest's exact null space — the formal
  version of "which detours leave no comma" (the §7 X-Trans/comma
  framing). PROBE-SIG-CHECKSUM on the existing Pillar-11 harnesses
  (jc forward/converse + hpc/pillar/signature.rs B7).

Neither adds a stored field to the tile. Both stay conditional on the
§10 honesty ledger; no kill condition touched. Blackboard entry appended.

Knowledge-doc suite green (117/117).

Warning

Review limit reached

@AdaWorldAPI, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 12 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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.

Please refer docs for additional details.
