Summary

• render MemoryPlugin grounding through ContextPack as reference material
• omit unevidenced memories from default grounding
• add session/tape-entry evidence fields to ContextPack EvidenceRef
• add G23 task packet and progress ledger

Review

• Local subagent review was requested but did not return within the configured timeout; manual staged-diff review found no P1/P2 issues.
• CodeRabbit is not a blocking gate per user instruction when unavailable or pending.

Summary by CodeRabbit

• New Features

  • Memory context now includes evidence-backed references with session and tape entry identifiers to trace memory origins.
  • Improved memory filtering and rendering for more accurate context grounding and selection.

• Documentation

  • Added G23 goal progress documentation detailing memory retrieval and evidence-backed reference context implementation.

📝 Walkthrough

Walkthrough

Memory grounding is converted from simple string-based system messages to evidence-backed ContextPack reference material. EvidenceRef gains optional session and tape-entry identifiers. MemoryPlugin.build_context() now renders memories through ContextPack with deterministic source hashing, and tests are updated to validate the new output format.

Changes

Memory Evidence-Backed Context Rendering

Layer / File(s)	Summary
EvidenceRef extension and rendering coding-agent/src/coding_agent/context_pack.py, coding-agent/tests/coding_agent/test_context_pack.py	EvidenceRef gains optional session_id and tape_entry_id fields that are serialized and rendered in evidence output. New test validates rendering of memory evidence with session and tape identifiers.
Memory plugin context-pack grounding coding-agent/src/coding_agent/plugins/memory.py	MemoryPlugin.build_context() is refactored to render memories as ContextPack sections instead of string messages. New helpers normalize summaries, convert evidence to EvidenceRef objects, and compute deterministic source_id via SHA-256 hash of normalized summary/tags/evidence.
Memory plugin test updates coding-agent/tests/coding_agent/plugins/test_memory.py	Fixtures now include evidence dicts. Assertions tightened to exact expected formatted output with evidence-referenced memory lines. New helper _repo_file_evidence() generates standardized evidence. Topic-scoped and tag-overlap tests adjusted to match filtering and output format.
Task specification and progress tracking coding-agent/.opencode/prompts/tasks/context-system-g23-memory-context-pack.md, coding-agent/docs/context_system/GOAL_PROGRESS.md	New task spec defines G23 acceptance criteria and scope. Progress entry documents implementation changes, test results, and remaining risks.

Poem

🐇 Hopping through memories with evidence in tow,
Session IDs dancing in context's grand show,
Hash-based sourcing, no mysteries remain,
Reference and render—a cleaner refrain!
