C · Block-0 creator-side inclusion (blocked until E5)

If the engine can carry a client-built creation bundle, it lands the create and creator buys in the same slot at least as often as the partner's current path.

draft

8 values must be agreed before this can run

Design

Why it matters: Block-0 launches whose bundled creator buys miss the creation slot get sniped and lose the supply they were meant to catch.
Unit: One launch submitted by the partner.
Primary metric: same_slot_inclusion: Share of launches where create and all bundled creator buys land in one slot (Δslot = 0 from the create tx's own slot).
Denominator: Every enrolled launch.
Randomization: Seeded CSPRNG per launch, auditable by the partner (per_launch_sha256_v1)
Stopping rule: Fixed n agreed with the partner.

Arms

Arm	What it does
rout carrier	Partner-built bundle submitted through Rout.
partner path	The partner's existing submission.

Secondary metrics

Metric	Definition
`external_buys_before_creator`	External buys ordered before the last creator buy in the same block.

Exclusions, decided before the run

None. Every intent stays in the denominator.

Acceptance

Criterion	Agreed value
`min_same_slot_difference`	Not agreed
`max_new_fingerprint_signals`	0

What each tier hides

Signatures, slots and ids are never redacted: they are how anyone re-checks a result. A run can't be published wider than the tier it was registered at.

Partner-confidential removes: host_id, nonce_account, stratum
Public also removes: mint, size_raw, quote, endpoint_region, refusal_code, send_error
