SWE.2/SWE.3 Baselines Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add reviewable SWE.2/SAD and SWE.3/SDD baselines so the DV document chain is no longer missing the architecture and detailed design layers.

Architecture: Keep SWE.2 in docs/architecture/sad.md and SWE.3 in docs/architecture/sdd.md, matching the README document tree. Update DV traceability and verification-plan wording to consume these baselines while preserving honest limitations for areas that still need deeper detail.

Tech Stack: Markdown, existing SysDes/SRS baselines, current Flutter/Rust workspace structure.


Task 1: Write SWE.2 SAD Baseline

Files:

  • Create: docs/architecture/sad.md

  • Step 1: Create SAD with architecture views

Write sections for purpose, upstream sources, components, static view, runtime flows, interface catalogue, dependency rules, non-functional allocation, architectural decisions, verification handoff, traceability, and open architecture risks.

Task 2: Write SWE.3 SDD Baseline

Files:

  • Create: docs/architecture/sdd.md

  • Step 1: Create SDD with module designs

Write sections for purpose, upstream sources, module catalogue, detailed API/data/state design, persistence, diagnostics, platform adapters, build/release design, verification hooks, traceability, and open detailed-design risks.

Task 3: Update DV Traceability

Files:

  • Modify: docs/governance/traceability-matrix.md

  • Modify: docs/verification/verification-master-plan.md

  • Step 1: Remove SAD/SDD missing limitation

Update traceability text so it says SAD and SDD baselines exist, with known depth limitations instead of missing-document limitations.

  • Step 2: Update verification plan inputs

Update verification master plan to reference SAD and SDD as current inputs for SWE.4/SWE.5.

Task 4: Verify SWE.2/SWE.3 Pack

Files:

  • Inspect created and updated docs.

  • Step 1: Sentinel-language scan

Run the sentinel-language scan over docs/architecture, docs/governance, and docs/verification.

Expected: no matches introduced by this baseline pack.

  • Step 2: File presence check

Run: ls docs/architecture

Expected: sad.md and sdd.md are listed.


Self-Review

  • Spec coverage: creates SAD and SDD baselines and updates DV traceability consumers.
  • Placeholder scan: no incomplete instructions are present.
  • Type consistency: document names match README paths.
