feat(linkedin-studio): N15 — do-next-kontrakt (recordDoNext + skrivere/lesere + forrige-utgave-kalibrering) [skip-docs]

Måling som ikke endrer neste utgave er teater: report/analyze/ab-test/48h-monitor
endte alle i chat (grep do.next = 0 i hele repoet). N15 gjør kanalen til en kontrakt.

- recordDoNext i hooks/scripts/state-updater.mjs (TDD, 17 nye tester): seksjonen
  Do-Next Directives, rader "[dato] (kilde) direktiv — evidence: peker".
  Levetid = erstatt-per-kilde + 60-dagers aldersgulv, maks 3 per skriv, additiv
  scalar last_donext_date, $-sikre replacement-funksjoner. CLI: --record-do-next.
- Skrivere: report Step 7b, analyze Step 6b, ab-test 2c.6 (kun Adopt),
  post-feedback-monitor (kun 48h-sjekken); analytics-interpreter emitterer nå
  anbefalinger på do-next-form (imperativ + evidens).
- Lesere: post/quick/batch/create Step 0 + newsletter Step 1, som i tillegg
  kalibrerer på forrige utgaves MÅLTE tall via queue-id-match (queue.json →
  analytics/posts) med eksplisitt honest-miss — aldri estimert.
- Guards: test-runner Section 16v (15 ubetingede sjekker, floor 198 → 213),
  $-safety-batteriet dekker recordDoNext (coverage-gate fanget den nye eksporten).

Suiter: test-runner 232/0, hooks 191/0, trends 300/0, brain 134/0, editions 72/0,
specifics-bank 45/0, contract-gate 33/0, tests 35/0, render 60/0.

+**Write recommendations in do-next form — imperative + evidence pointer.** The calling command
+persists the top 2–3 verbatim as do-next directives (`recordDoNext`, source `report`), and the
+create surfaces read them at Step 0 before drafting. So each one must be actionable by someone
+who never saw this report: "Plan 2 AI-agent posts this week" (imperative, checkable), not
+"AI content is performing well" (an observation nobody can execute). The evidence pointer is
+what lets the next session judge how much weight a directive carries — always name the measured
+number and the sample it came from.
