Audited literal point-link lifting and dual colored-incidence canonicalization before any two-profile frontier census.
ProgressThe prerequisite gate passed and produced independently checked research infrastructure. It did not enumerate a link frontier, solve an extension instance, produce a 54-cover, or exclude any cover. The exact range remains 54 <= C(15,5,3) <= 55.
Strategy and discriminatorcertified point-link frontier census
Exact projection/lifting controls plus dreadnaut and independent partition-refinement canonicalization determine whether a later orbit census has a sound representation.
Hypothesis: The proposed point-link census representation preserves literal global lifting data on the maintained 55-cover, and two independent colored-incidence canonicalizers are stable on both forced link profiles.
Test: Project roots 1 and 15 of the maintained 55-cover, lift them exactly, reconstruct the pair matrix and common blocks, and cross-check three profile controls under 1000 producer and 64 independently generated relabelings per case.
RationaleExact source reconstruction, two materially different canonicalization encodings, thousands of relabeling controls, byte-identical regeneration, hash binding, and mutation rejection support the narrow infrastructure claims. None of those controls supplies exhaustive coverage of the unknown link or cover spaces.
Claims requiring scrutiny- At roots 1 and 15, the maintained 55-cover's literal point-link projection and residual family lift exactly to the original cover, reconstruct its global pair matrix, and agree on six literal common blocks.
- The displayed 7,5^13 link and both displayed 6,6,5^12 links are asymmetric as degree-colored incidence structures; the two ordinary links are isomorphic.

Computational experiments- .proof-experiments/20260809-073211-7b1376: PASS in 28.286 seconds; exact lift and canonicalization controls passed, with no frontier enumeration.
Independent checkercheckers/check_link_lifting_canonical_gate_v1.py independently reparses bit masks, reconstructs both lifts and common blocks, rebuilds both graph encodings, runs 192 distinct relabelings, and imports no producer code.

Cross-domain transfers tested- Certified forced-link proofs in covering designs -> literal links need a complete lifting map before orbit leaves can support a global exclusion -> the maintained 55-cover passed the exact projection/lift control, but global frontier completeness remains untested.
Established facts- Both tested source-cover point-link projections lift exactly and reconstruct all global pair multiplicities.

Ruled out in this epoch- Treat a positive-control link or special-star census as a globally complete exclusion partition.
Any future point-link frontier work lacking an explicit literal lifting map and global pair-excess scope. · Local degree-colored links forget global pair-excess data away from the root; this gate validates representation only on two known source projections. · protocol scope and exact lift audit · A complete link census plus extension instances that explicitly leave every global skeleton free or partition all skeleton cases, with replayed proofs.
Open leads- Complete special-star frontier bin.
It directly measures whether the certified link-census route is capacity-feasible. · Enumerate the smallest q bin with canonical representatives and orbit accounting. · high · open - Hamming-radius exact-pair repair.
A materially distinct constructive route could produce a seed without classifying links. · Run exact radius-two repair on fixed predeclared low-defect states. · normal · open - Literal refinement of the 395 type-4 signatures.

Continuation checkpointObjective: Measure the smallest complete special-star frontier bin.
First action: Implement the incremental 14-bit/91-bit q-bin generator and emit every retained representative with stabilizer data.
Stop condition: Canonicalizer disagreement, orbit-accounting mismatch, incomplete coverage, or more than 120 representatives.
Next moves- Implement incremental special-star enumeration with 14-bit point and 91-bit pair masks.
- Complete the smallest q bin and retain every canonical representative.
- Require dreadnaut/refinement agreement and a third labelled orbit-stabilizer count; stop above 120 representatives.
