Runtime & State Overhaul — Engineering Notes

Status: Design exploration complete; handed to @robertDouglass for ADR finalization Owner: Architecture (Architect Alphonso persona) + Stijn Dejongh Parent epic: Priivacy-ai/spec-kitty#992Epic: drain the bug queue by repairing domain boundaries (this is its execution-state / context-ownership slice) Redesign tracker: Priivacy-ai/spec-kitty#1666Execution-state & context domain-boundary redesign (child of #992, blocks #1619) Anchor issue: Priivacy-ai/spec-kitty#1619Epic: Unify mission execution context across coord/main/lane topology Down-payments: #1663 (MissionRun→Mission ref) · #1664 (status/ boundary enforcement) Started: 2026-06-03


Why this directory exists

Spec Kitty keeps shipping point-fixes for the same structural failure class: command surfaces independently re-derive where mission state lives, which branch is authoritative, and what the agent should be told — so reads, writes, and prompts disagree. PR #1627 closed four concrete child bugs (#1615–#1618) but the parent epic #1619 stays open for the structural fix: one canonical execution-context authority resolved once and threaded through every surface.

These notes are the grounding layer for co-authoring that to-be design. They capture the problem, the current code, the architectural intent, and the governing doctrine before we commit to a design, so the design conversation is anchored in evidence rather than memory.

This is not a decision record yet. No design option is selected here. The final document (06) proposes candidate domains/splits and frames the open design questions we will resolve together. ADRs follow once we choose.

Reading order

# Document Purpose
00 README.md This index
01 01-ticket-capture.md Failure modes, evidence, and suggested implementations from #1619 + children (#1615–#1618) + related (#1602, #1348) + the #1627 fix
02 02-current-state-map.md How the codebase derives "mission execution context" today, per surface, with the post-#1627 residue
03 03-architecture-context.md 3.x architectural intent (ADRs), the 2026-05-25 deep-dive review, and the CAACS audits
04 04-doctrine-constraints.md The binding DDD doctrine (DIRECTIVE_001/031/032, paradigms, tactics) that constrains any domain split
05 05-architectural-synthesis.md Aggregated architectural reading: root cause, forces, invariants the design must satisfy
06 06-proposed-domains-and-splits.md Technical concretization (rewritten) — maps the validated model (17) to package homes + API entry points; net-new vs existing; the communication-artefact + Effector targets; Strangler sequencing tied to #1663/#1664
07 07-existing-pattern-and-domain-extraction.md The existing doctrine/charter infra-context pattern to mirror; the OperationalContext naming collision; MissionStatus aggregate + MissionFlow FSM extraction assessments (refines 06 §2/§6)
08 08-architecture-phase-1-summary.md Phase 1 checkpoint — standalone summary of problem, findings, invariants, decided vs open
09 09-context-decomposition-model.md Phase 2 — the conceptual model: Context as composition of domain-owned fragments (infra/filesystem/VC/preferences/state) → fit-for-purpose composites
10 10-context-needs-capture.md Phase 2 requirements — what each actor (code/user/agent) must know at each lifecycle step, across the six dimensions. Lens 1 = intuition; lens 2/3 corroboration in 11
11 11-dialectic-and-revised-claims.md Dialectic — corroborate-vs-refute pass on our claims. Key correction: harden the existing ActionContext (ADR 2026-03-09-1), don't greenfield; policy frozen-at-plan; behaviour single-owner; phase derived-not-added
12 12-actor-mental-model.md Abstraction level up — the actor mental model: human / LLM / external system × {sense of self, purpose, environment} mapped to AgentProfile, Charter, Mission, Context. §5a: the Mission is layered (mission + WP state)
13 13-dialectic-mission-vs-missionrun.md Dialectic — "Mission ≡ MissionRun?" Refuted (1:many cardinality; distinct storage/id/lifecycle). Salvaged: the layered state belongs to Mission; MissionRun is the ephemeral driver and is degenerate in code today
17 17-consolidated-domain-model.md Consolidated model (baseline) — code-validated; supersedes 14 Tier 1. Per-domain Contexts (Governance/Execution/Infra) + Shared Kernel code module; Status/kanban shared context; Actor↔Effector; prompt = communication artefact. Maps to 06 next
16 16-codebase-reassessment-fanout.md Codebase reassessment (Debbie/Pedro fan-out, H1–H6) — code confirms every dialectic refutation + 5 emergent findings (Status is a shared context; Actor fragmented; 3 projections; MissionRun gap; runtime home stale). Evidence base for 06 mapping
15 15-dialectic-on-the-domain-model.md Dialectic on the design — core (Mission≠MissionRun aggregate) survives; refuted: Context-as-Execution-subdomain (→ Shared Kernel/OHS), Actor-in-Execution (→ cross-domain), Prompt-as-DTO (→ Published Language). Consolidation checklist before mapping to 06
14 14-model-diagrams.md Multi-tier diagrams (Mermaid) — Tier 1 domains (Governance · Mission Management · Execution/Runtime, with Context as a subdomain; Actor realized in Execution; Executor Prompt as boundary DTO) + interrelations; Tier 2 drill-downs; BPMN swimlane; governed-invocation sequence; three-senses overlay
