refactor(ms-ai-architect): R14 — persona ut av plugin-flaten, og de seks stedene som produserte den

Nøytral arkitekt-ramme (ratifisert 15.09) i SKILL.md-ene, 23 kommandoer, 70 redaksjonelle
forekomster i ref-korpuset, README/CLAUDE.md/NOTICE og A11Y-rapportens proveniens-linje.
Hver av de 70 avgjort i kontekst: dialog fikk ny taler, proveniens ny opphavspåstand.

Ordren navnga fem produsent-steder; den live sjette manglet. `PROMPT_TEMPLATE` settes i
generate-skills.sh:27 og leses ALDRI — prompten er en heredoc i samme script. Å rette bare
prompt-template.md ville latt generatoren re-minte personaen ved neste KB-kjøring.

Ny G4-klausul i check-cosmo-gate.mjs: persona i leveranseflaten = 0, derivasjonsregisteret
pinnet per fil PÅ TALL (et filnavn-unntak er blindt for hva fila senere inneholder).
Registeret utvidet med README.md 3 — versjonstabellens rader er historikk, ikke leveranse.
Den ene genitiv-formede produktlinja adjudiseres på cosmos-db-URL-en i samme rad; regelen
er målt lukket (8 tvetydige linjer totalt, 33 URL-linjer, 2 persona-klassifiserte, begge
produkt) og hvitvasker ikke bar `Cosmo`. classifyCosmo urørt — baselinene hviler på den.
R3 godtar nå R14-utført (0) men ingenting imellom: et halvveis sveip felles fortsatt.

Bevis: gate PASSED + NETTET VALIDERT BEGGE VEIER · 1137/1137 · validate-plugin 250/0/0 ·
begge --dry-drivere 0 · Layer B 45/45 OK (kjent-positiv feller, exit 1).

+// ================================== R14: the delivery-surface clause ======================
+//
+//   G4  persona occurrences in the DELIVERY SURFACE = 0.
+//
+// Delivery surface = tracked `*.md`, minus the reference corpus (G1/G3 already own it) and
+// minus the derivation register — CHANGELOG rows, docs records and the measurement document
+// itself, all TRUE statements about the past that CLAUDE.md forbids rewriting.
+//
+// The register is pinned on PER-FILE OCCURRENCE COUNTS, never on filenames. Measured: inject
+// one new persona line into an exempt file and the count moves, so a number-pinned exemption
+// FELLS it while a filename-pinned one is blind to it. That is the difference between an
+// exemption and a hole.
+//
+// The one adjudicated product line: `docs/ref-kb-gold-reconciliation-2026-06.md:93` reads
+// "Cosmos multi-region writes (active-active)", which the R13 Norwegian-genitive rule scores
+// as persona because the enumerated PRODUCT_FOLLOWERS list was built over a corpus with no
+// English product prose. The verdict was settled by the `/azure/cosmos-db/` URL in the same
+// table row, so G4 applies THAT discriminator rather than exempting the file. Measured over
+// all tracked `*.md`: 8 `Cosmos <lowercase>` lines exist in total and 33 lines carry a
+// cosmos-db URL — of those, 2 classify as persona and BOTH are genuinely the product, so the
+// rule is closed, not open-ended. The classifier itself is untouched: G1/G3/R1/R3 baselines
+// rest on it.
