Add typed S0-S6 multi-origin join terms

[erinepshovel-code]

Repair complete: green and review-clean

This repairs EPAC #10 against merged METAPAT #34. The earlier hold and old producer pin are superseded. Final review bound the exact head/base below: all five checks succeeded, all eight review threads were resolved, and GitHub reported the PR mergeable with a clean merge state. The guarded merge succeeded as a037aec400b5a1fce7e9eb7411b2ae4aa0c742aa, preserving the validated tree.

What changed

The producer requires stored state to remain distinct from scalar readouts and grants no Vector license to static bearing. Transformation and Time require result and occurrence evidence that this static constructor does not have.

Wire 0.2.0 therefore retains all seven origins, six authored relations, exact state, seating, holes, leftovers, provenance, equality, and public recovery while:

• separating stored phase/capacity/facing properties from readouts that identify their origin, measured property, rule, and value;
• retaining static bearing as sign readouts, with no Vector claim;
• replacing the pre-merge JoinTransformation/transformations/transformation_id/sequence API with AuthoredJoin/joins/join_id/order, and claiming structural adjacency rather than Transformation or Time;
• rejecting unreduced wire ratios, normalized payload changes, and noncanonical original JSON text (key order, whitespace, trailing newline, negative zero, and unnecessary Unicode escapes);
• making the documented generator work without an installation and rejecting mismatched roots or loaded source before writing evidence.

The exact merged producer fixture is packaged byte-for-byte and checked against the consumer's role projection. Both work graphs, provenance, source/fixture hashes, and generated evidence are rebound. All 14 non-generated feature inputs are covered. No state-change or temporal evidence is fabricated.

Review evidence

All eight threads were reread against the repaired exact head. Each is addressed; none remains unresolved at this review.

Thread	Repair / verification
PRRT_kwDOUPneN86nA-Z6	Direct generator subprocess with -S, no site packages, and an external working directory reports both artifacts CURRENT.
PRRT_kwDOUPneN86nBQEl	Foreign checkout and mismatched loaded-module source are rejected before output writes; identical installed module bytes remain supported for artifact replay.
PRRT_kwDOUPneN86nY02M	Original JSON text must equal the recovered tree's canonical serialization; all six alternate encoding regression cases fail while canonical UTF-8 round-trips.
PRRT_kwDOUPneN86nCgp6	Nonzero/zero phase and phase/occupancy readout ratios fail when unreduced, with both retained and recomputed digests.
PRRT_kwDOUPneN86nA-aD	Digest-consistent duplicate leftover identity fails global origin/join/leftover uniqueness.
PRRT_kwDOUPneN86nA-aH	The complete base-to-head feature diff matches all 14 manifest inputs, excluding only the two generated outputs.
PRRT_kwDOUPneN86nA-aM	Source-only generator uses a file-location loader while the candidate stays imported from the installed artifact; all six final installed-artifact suites pass.
PRRT_kwDOUPneN86nA-aP	Nested semantic mappings remain immutable; attempted mutation leaves existing candidate bytes unchanged.

Validation

Final exact-head CI run 36670392280 succeeded:

Runtime	Installed wheel	Installed source archive
Python 3.10	245 tests + 23 subtests passed	245 tests + 23 subtests passed
Python 3.11	245 tests + 23 subtests passed	245 tests + 23 subtests passed
Python 3.12	245 tests + 23 subtests passed	245 tests + 23 subtests passed

• CodeQL and workflow analysis also succeeded.
• Clean normalized wheel/sdist build and Twine passed with pinned CPython 3.11.15 and compile/runtime zlib 1.3.1.
• Downloaded Python 3.11 CI evidence binds this exact head/tree, reports zero skips, and retains all 14 comparison standings as FALSIFIED. Both packaged artifacts are byte-identical to the local normalized build.
• Direct/module generator drift checks, all 14 feature input hashes, producer commit/tree/application/source/fixture identities, and work-graph digest pass.
• All 17 declared contracts, checks, and test functions reconcile.
• Four original-head constructor variants preserve state, seating, numeric bearing/occupancy, provenance, adjacency, lineage, and bags.
• All six noncanonical JSON encoding witnesses were accepted by predecessor 254804f and are rejected by final head 86f1831.
• Every live thread was reread after the final matrix completed. There are no unresolved findings or change-requesting reviews.

Usage and explicit API migration: docs/multi-origin-join-term-v0.md. Run python tools/generate_join_term_v0.py --check and the repository's clean artifact replay workflow.

hmmm: this remains public representation research. Molecular-shape standing remains FALSIFIED. No Vector action, Transformation result, actual Time sequence, chemistry, physics, UCNS correspondence, energy coupling, secrecy, computational hardness, PCEA compatibility, production suitability, or release authority is established.
