Original evidence
Verbatim or source-bound records retain the strongest trace back to the completed turn.
ARCHITECTURE / MEMORY EVIDENCE
Every recalled fact keeps its boundary and source.
TMCRA resolves two recall scopes in parallel, composes Source, Fast, and Slow memory paths, preserves actor provenance, and returns bounded Prompt Evidence to the Agent.
01 / SCOPE MODEL
Cross-session memory without cross-project leakage.
Session is a stable grouping and provenance identifier inside a Project Scope. It is not a third recall scope beside Global and Project.

02 / LAYERED RETRIEVAL
Three memory paths, one evidence contract.
Recent working state
Fresh events and progress become available quickly for the next relevant question.
Longer-term structure
Background organization resolves subjects, changes, contradictions, and relationships over time.
Prompt Evidence
Role composition and bounded packing preserve the selected memory IDs, actors, scopes, sessions, time, and source links.
03 / ACTOR PROVENANCE
User requirements and Agent progress remain different records.
Both can be recalled because both matter to continuity. Their role labels, colors, source fields, and display lanes remain distinct.
Requirements and facts
“Keep every small section fully designed.”
COMPOSE, DO NOT MERGE
Progress and results
“The design architecture is complete; homepage implementation is in progress.”
04 / TURN COMPLETION
Recall before the answer. Write after the answer.
When the completed answer is available, TMCRA persists the user and assistant messages as two separate records for future turns.
