Context: Rich stated 2026-04-22 “we now have our most solid plan yet, so it is worth spending time to ensure our plan is watertight.” This shifted the research posture from speed to thoroughness.

Total: ~26 agent-runs across 6-7 hours wall-clock. Agents run dependency-ordered (later waves can cite earlier findings).

Why staged, not single-burst

  • Dependencies exist — Z-ONTOLOGY depends on Z-PARADIGM; Z-MARKETPLACE depends on Z-ASSETS; Z-FAITH depends on Z-UK-LAW + Z-SCOPE + Z-CAPACITY
  • Gaps only appear in cross-reference — single-burst agents can’t see each other’s work
  • Watertight requires adversarial review — Wave 6 is where real stress-test happens
  • Wave-3+ agents can cite Wave-1+2 findings, enriching evidence graph

Z1-Z5 disposition (DEFERRED)

Three options still on table (Rich to decide):

  • (a) Re-dispatch all 24 including refresh of Z1-Z5 under expanded scope
  • (b) Dispatch only 19 new (Z6-Z24); existing Z1-Z5 notes stay as-is
  • (c) Hybrid — dispatch 19 new + one staleness-review agent that flags which Z1-Z5 findings need refresh under Ⅲ + D-ii + α_max

My recommendation: (c) hybrid — cheapest, evidence-driven, doesn’t duplicate ~200 ULID-cited quotes still valid.

Preparatory commits needed before Wave 1 launches

  1. architecture-proposal v1.5 committed (Ⅲ + D + α_max + mitigations + 7-module + ε+δ + 30-48 mo)
  2. 24 Z-stub notes files created at ~/off-github/library/projects/inherit/Z{N}-notes.md
  3. 24 research-request YAML blocks added to ~/off-github/library/research-requests.md
  4. Memory updates: this file + supersede project_scotland_as_second_jurisdiction.md + new project_v2_architecture_locked_2026_04_22.md + new project_partner_model_three_shapes.md

Each research agent produces

Notes file at ~/off-github/library/projects/inherit/Z{N}-notes.md with:

  • Requirements this spine addresses (from v1.5 + relevant mega-spec claims)
  • Library evidence organised by sub-topic (ULID-cited quotes with backlinks)
  • Findings contradicting current plan (adversarial)
  • Gaps + open questions
  • Cascade recommendations (specific claim edits)
  • Cross-references to other Z-files

Session-continuation rule

Waves can run across multiple sessions — each wave commits its artefacts before the next launches. No single-session requirement.
