AFMNativeToolTurnSession accumulates the transcript across iterations (was dropping context on each send — the agent sends only deltas). 2. Removed dead renderForNativeSession (no call sites after reverting to the text-catalogue renderer that scored 7/10 in eval). 3. Removed unused `iteration` var. 4. Persona carve-out trimmed to fit Mini's 1/3-window budget (1369→1357). 5. Pocket core hash re-pinned for the new persona text. 6. MemoryGroundingTests snapshots updated for the new RULES wording. 7. MiniPromptBudgetTests passes with the tighter carve-out.
