   Goalpost 0 dependency posture — 2026-07-07

   Goalpost 0 is a coordination anchor, not a code landing requirement. Current dependency decisions:

   • Echo PR #644 is parked as non-blocking for Goalpost 0. TraceRunReceiptV0 may start as a fixture-backed receipt shape. WAL durability becomes a hard dependency later, when Goalpost 2 claims a real Core Trace and Goalpost 6 claims retained evidence verification.
   • Edict PR #134 is parked as non-blocking for Goalpost 0. Its obstruction/counterfactual taxonomy is relevant to EchoProofPlanV0, but the first proof-plan fixture can carry a provisional obstructionTaxonomyVersion and align once #134 lands.
   • Continuum PR Feat: add qw runtime projection commands #28 is parked as non-blocking for Goalpost 0. Runtime projection commands are useful later, but the first vocabulary work should remain a fixture envelope and should not freeze a broad protocol family.
   • Xyph has no open PR. The first Xyph task is fixture/product anchoring, not enforcement or UI.

   This preserves the first campaign invariant: one protected workflow, one aperture, one target trace shape, one issue per repo, and no repo claiming more than the artifact proves.

   GP0 is complete.

   Final campaign decisions:

   • Campaign: Xyph Gate Alpha
   • Protected workflow: payment_receipt_required@0
   • Aperture: payment_reliability@0
   • Proof-plan shape: EchoProofPlanV0
   • Trace shape: TraceRunReceiptV0
   • Evidence envelope: WitnessCapsuleV0
   • Diff shape: HorizonDiffV0
   • Obligation shape: ObligationV0
   • First policy question: can capture:success happen without durable receipt obligation satisfaction?
   • Product mode: shadow verdict before enforcement

   Successor GP1 issue: #78

   GP1 freezes the fixture evidence vocabulary. GP0 remains the historical campaign grounding record.
