nx_capgraph_edges.nx

nx_capgraph_edges.nx -- DERIVES the capability graph's prerequisite edges FROM THE IMPORT CLOSURE. WHY (debt 1785518444, filed by me 2026-07-31): nx_capgraph_derive shipped reading a HAND-DECLARED edge file. Declared edges are a seed, not a measurement, and a MISSING edge is the dangerous case -- it lets a dependent read healthier than the layer it stands on. This organ replaces the declaration with a measurement. THE MEASUREMENT, end to end, no taste anywhere in it: 1. OWNERSHIP comes from knowledge/compare/<domain>.matrix, which already maps every domain to the real organ SOURCE PATHS backing each of its capabilities (field2), with field3 = the symbol. Rows whose symbol is _ABSENT_ are declared GAPS -- skipped, they own nothing. 2. DEPENDENCY comes from the source itself: every `import "<module>.nx"` in an owned source. 3. EDGE: if a source owned by domain A imports a module owned by domain B (B != A), then B is a PREREQUISITE of A. That is a fact about the build, not an opinion about the architecture. ⚠THE MEASURED GRAPH IS NOT ACYCLIC. Probed 2026-07-31: search>webscraping, browser>webscraping AND webscraping>browser, search>deepresearch AND deepresearch>search, comms>videoops AND videoops>comms. Mutually-importing domains are REAL. This is not a defect in the measurement and must not be "cleaned up" by dropping edges: a cycle is a genuine finding -- it names a CO-DEPENDENT CLUSTER that can only be raised together. The consumer's min-relaxation is a fixpoint iteration bounded by node count, so it converges on a general digraph; the cycle members simply share a floor. HONEST ENVELOPE, emitted into the file itself so no reader has to trust this comment: - coverage is bounded by the matrices, not by this organ: a domain with few matrix rows yields few edges. That is a matrix-completeness gap, and it is REPORTED, never silently treated as "no deps". - matrix rows pointing at sources that do not exist on disk are COUNTED and reported (missing=N). - first-wins ownership when two domains claim the same module; ambiguity is COUNTED and reported. nx_capgraph_edges [outfile] exit 0 ok | 4 capture-fail | 5 write-fail license_tier: ORIGINAL No hw writes (Rule 26). expect_exit: 0
