feat(linkedin-studio): SB-S3c — cross-silo id-threading + post→analytics assembler [skip-docs]

Hub-side design: the published record now carries the specifics/trends ids
it was built from (additive, omit-empty → byte-backward-compatible), and a
new pure assembler (scripts/brain/src/assemble.ts + `brain assemble`) joins
post↔analytics by normalized title-prefix + date with honest confidence
tiers (high/low/none). Answers the arc's north-star query: which raw
material actually performs? (specific → post → measured analytics).

All four tributaries untouched (analytics READ-only via inlined raw-JSON,
no package import); profile.md grammar untouched (the fact→post link stays
OUT — C-1). The repeatable --specific/--trend ingest flags collect via a
new collectRepeated helper, leaving parseFlags untouched.

TDD: 19 new brain tests (ingest 4 + publish 3 + assemble 8 + cli 4), all
SC1–SC12. brain 113/113, gate 95/0/0, BRAIN_TESTS_FLOOR 94→113,
ASSERT_BASELINE_FLOOR unchanged at 80. Light-Voyage hardened
(brief-review 5 FIX · plan-critic 1 BLOCK+4 MAJOR+4 MINOR · scope-guardian ALIGNED).

# Brief — SB-S3c: cross-silo id-threading (the "which raw material performs?" graph)
> **Slice:** SB-S3c (third sub-slice of SB-S3). **Status:** DRAFT — awaiting operator "go" before any code. Light-Voyage **complete**: brief-review **APPROVE-WITH-FIXES** (5 FIX folded §9), plan-critic **REVISE → 1 BLOCK + 4 MAJOR + 4 MINOR folded** (§10), scope-guardian **ALIGNED** (0 creep/0 gap).
> **Slice:** SB-S3c (third sub-slice of SB-S3). **Status:** **LANDED** — operator go 2026-06-23; TDD complete, brain suite 113/113, gate 95/0/0 (`BRAIN_TESTS_FLOOR` 94→113, `ASSERT_BASELINE_FLOOR` unchanged at 80). Light-Voyage: brief-review **APPROVE-WITH-FIXES** (5 FIX folded §9), plan-critic **REVISE → 1 BLOCK + 4 MAJOR + 4 MINOR folded** (§10), scope-guardian **ALIGNED** (0 creep/0 gap).
> **Predecessors:** SB-S0 (id/provenance substrate — `mintEntityId`/`mintContentId`, `id.ts:6-7` reserved "SB-S3 will thread this id through the tributaries") · SB-S1 (published-gold ingest — the post anchor `ingest/published/<contentId>.md`) · SB-S2 (consolidation motor) · SB-S3a (first reader `strategy-advisor` — LANDED `4fa411f`) · **SB-S3b (supersede arm — LANDED `585f972`, gate 95/0/0, BRAIN floor 94, ASSERT floor 80).**
> **Grounded in:** a read-only code map of all four tributaries + `scripts/brain/` (file:line cited throughout) — Explore sweep + firsthand reads of `id.ts`, `consolidate.ts`, `types.ts`, `profile.ts`, `ingest.ts`.
