Supersedes #6127: same single move commit with the seat-2 findings folded in, still one commit and one ticket.

1. ml-tuner documented as a deprecated no-op (Cargo.toml still declares ml-tuner = []).
2. check_tuner_test_move.sh reads CI fragments 295 and 298 (mutants S16, S17 turn it red); the false L6 label is gone.
3. The unproven "proved in the PR body" claim is replaced by what is true: compared at move time, digests pin the bodies now.
4. grep rc>=2 fails closed (mutant S18 isolates it: red with the guard, green without).

--self-test: 26 passed, 0 failed; live check green.

Seat 1 (aprender-w5018, non-author) @d7ae7120bfa070d4427ea0ac605cb88a77e7adb4 — NOT SEATED, scope check (c164) fails at seat time.

verdict: HOLD
patch-ids: 1cd74457a7d4

Scope: one commit, one ticket (PMAT-Ticket: PMAT-5803), diff matches the title (drop aprender-compute dev-dep on aprender-core, move tuner tests to aprender-core, LAB night guard, 295/298 cmd fragments). Merge-of-main only, 2 parents on the head.
Blocker: PMAT-5803 has no roadmap entry — no docs/roadmaps/entries/PMAT-5803.yaml and no 'id: PMAT-5803' in roadmap.yaml, on this head or on main — so pmat cannot read the ticket this PR claims.
Fix: add the entry (fragment + roadmap.yaml append), push as a new commit; I will re-seat bound to the new head. The code half I did not re-verify until scope is readable.

§13.11 rung 1 — quorum shadow verdict

S13-SHADOW pr=6148 head=d7ae7120bfa070d4427ea0ac605cb88a77e7adb4 verdict=REFUSE class=Q1 arm_rc=1

Shadow mode: this records a verdict and merges nothing. A refusal
to arm is not a block (§13 adds zero rows to §7) — the pull request is
exactly as green as it was.
