feat(linkedin-studio): N23 — positioning-brief-motor (generering + konsum) [skip-docs]

Persistert posisjonering som alle drafts bindes mot. Innplassert i
/linkedin:setup (Step 3g) etter operatør-friksjonskriteriet — setup eier
allerede ${DATA}/profile/ og har menyen; telling forblir 30.

- config/positioning-brief.template.md (NY): fire seksjoner (Who I am ·
  Who this is for · What I hold · How I differ), hver med _Evidence:_-linje.
- setup.md Step 3g: DELEGERER til linkedin-studio:strategy-advisor.
  Brain-konsum-blokken forblir i én kopi (N21-lærdommen), lint-håndhevet.
- strategy-advisor.md: distillasjonen, kildepresedens, anti-flatteri
  (What I hold må bære påstander en leser kan være UENIG i) og
  evidensgulv ([insufficient evidence] framfor plausibel oppfinnelse).
- Distillat, ikke andre profil: briefen REFERERER user-profile.md framfor
  å gjenta den. Operatørens deklarasjon og daterte anker slår maskinens
  inferens; motstrid rapporteres som spenning, aldri stille anvendt.
- Konsum: post/quick/batch + newsletter Step 1 + differentiation-checker
  (scorer originalitet mot How I differ, ikke generisk nyhet).
- Regenerering er operatør-gatet: explicit go + seksjonsvis diff + aldri
  stille overskriving av operatørens egne redigeringer.

Lint: Section 16y, 17 nye ubetingede sjekker (self-test 1 akseptert /
4 underspesifiserte avvist). Floor 251 → 268. Alle ti suiter grønne:
test-runner 270→287/0 · trends 300 · analytics 202 · hooks 191 · brain 134
· editions 72 · render 63 · specifics-bank 45 · tests 35 · contract-gate 33.

+# Positioning Brief
+
+> **What this file is.** A distillate — the second brain's evidence-weighted read of your
+> positioning, written by `/linkedin:setup` (Step 3g) and consumed by every drafting
+> surface. It answers four questions a draft cannot answer for itself: who is writing,
+> who it is for, what they actually hold, and why it is not interchangeable with the
+> other twenty posts on the topic that week.
+>
+> **What this file is not.** It **does not restate** `user-profile.md`. That file is your
+> *declared* identity — name, role, the five expertise areas, the target audience, the
+> ranked goals — filled in by you and authoritative as such. This file is the *distilled*
+> layer above it: the stance and the difference, inferred from what you have actually
+> published and consolidated into `brain/profile.md`. When the two disagree, the declared
+> profile and your dated `## Who I am now` anchor win, and the inference is the thing that
+> gets corrected. Two files asserting the same fact is how positioning quietly forks.
+>
+> **Editing.** This file is yours to edit directly. Regeneration never overwrites it
+> silently: `/linkedin:setup` shows a diff and asks for an explicit go first.

+
+## Who I am
+
+[One or two sentences. The working identity a reader would recognise across your posts —
+not your job title. Distilled from `brain/profile.md` Static facts and the operations
+anchor; grounded in what you have published, not in what you aspire to.]
+
+_Evidence:_ [which consolidated facts or published pieces support this]
+
+---
+
+## Who this is for
+
+[The reader you are actually writing to — the one whose problem your posts solve. Narrower
+than the declared target audience if the published record says so; say which, and why.]
+
+_Evidence:_ [engagement patterns, recurring commenters, the questions you actually get]
+
+---
+
+## What I hold
+
+[The two to four positions you argue from — the opinions a reader could disagree with. A
+position that no one could disagree with is a description, not a stance, and does not
+belong here.]
+
+1. [Position — stated as a claim, not a topic]
+2. [Position]
+3. [Position]
+
+_Evidence:_ [posts or editions where you took this position explicitly]
+
+---
+
+## How I differ
+
+[Why this account and not the generic account on the same topic. Concrete: the lived
+material only you have — the named cases, the real numbers, the work you actually did.
+"More practical" and "more authentic" are not differentiators; the specific thing you can
+say that a competitor cannot is.]
+
+_Evidence:_ [specifics-bank entries, case studies, frameworks you authored]
