Summary

• add ADR-0073 for SQLite TopicStore parity on the local durable SQLite path
• add the implementation task packet for the next SQLiteTopicStore parity PR
• capture reviewed gates for selected TopicStore wiring, fenced SQLite mutations, semantic rebuild authority, Helm defaults, and docs acceptance

Verification

• git diff --check -- docs/adr/0073-sqlite-topic-store-parity.md .opencode/prompts/tasks/sqlite-topic-store-parity-task-packet.md
• local subagent review, storage/schema/fencing focus: no P1/P2 findings after fixes
• local subagent review, product/runtime/semantic/Helm focus: no P1/P2 findings after fixes

Implementation code is intentionally out of scope for this PR.

Summary by CodeRabbit

• New Features

  • Added guidance for a new durable SQLite topic store path, alongside the existing PostgreSQL-backed path.
  • Clarified when the app should select SQLite, PostgreSQL, or no topic store based on runtime configuration.

• Documentation

  • Added an ADR describing topic-store parity rules, storage behavior, mutation safeguards, and runtime wiring.
  • Included implementation steps, test coverage expectations, and review/stop conditions for the work.

Adds ADR-0073 describing SQLite TopicStore parity, store-selection rules, SQLite storage guarantees, runtime wiring, and acceptance criteria, plus a task packet that records implementation scope, commands, and review gates.

Changes

SQLite TopicStore parity docs

Layer / File(s)	Summary
ADR background and selection rules coding-agent/docs/adr/0073-sqlite-topic-store-parity.md	Defines the ADR background and the product-layer rules for selecting a durable TopicStore across local SQLite, PostgreSQL, and non-durable modes.
SQLite store guarantees and runtime wiring coding-agent/docs/adr/0073-sqlite-topic-store-parity.md	Defines SQLite TopicStore schema and mutation guarantees, then threads the selected durable store into runtime creation and semantic maintainer setup.
ADR acceptance criteria and references coding-agent/docs/adr/0073-sqlite-topic-store-parity.md	Lists rejected alternatives, acceptance criteria, non-goals, and related references for the parity decision.
Implementation packet scope and gates coding-agent/.opencode/prompts/tasks/sqlite-topic-store-parity-task-packet.md	Defines the task packet scope, implementation steps, test commands, and review-stop conditions for the parity work.

Poem

I hopped through ADR ink and moonlit code,
Found SQLite carrots on the path I strode.
Two topic stores now twinkle in the burrow glow,
With tests as tiny lanterns in a row.
Hop, hop—my whiskers say “let it flow.” 🐇

136-148: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Clarify P1/P2 priority terminology.

The task packet references "P1/P2 review findings" (lines 137, 145) without defining these priority levels. While this may be established project terminology, consider adding a brief parenthetical or reference to where priority levels are defined, especially since this packet may be consumed by engineers unfamiliar with the project's review taxonomy.

44-84: 🧹 Nitpick | 🔵 Trivial

Add missing semantic_sync.py to the Context file list.

Both semantic_sync.py and semantic_recall.py exist in the codebase as separate, active files. The ADR-0073 correctly references semantic_sync.py, but the task packet's Context section omits it.

Add this file to the "Relevant files" list:

• coding-agent/src/coding_agent/topics/semantic_sync.py

Both files serve distinct purposes and should be referenced together for accurate implementation context.
