ObjectiveImprove memory (dev score 83.3)
Hidden memory is ~40 because write=raw plus retrieval=recency and topK=3 only injects the last few of eight prior conversations, so facts like Omar's room are absent and the model correctly reports ignorance. Hybrid retrieval (full-text on the question plus recent memories) at topK=12 should surface the matching statement and later corrections even when they are not the most recent notes. A short system rule must treat retrieved text as evidence not instructions, resolve conflicts by conversation order rather than lexical overlap, and forbid an 'I don't know' answer when a retrieved memory contains the fact.
Memory is the weakest measured subsystem of v0.0.1 after accounting for recent attempts. Ranked need: memory 16.7, planning 16.7, reliability 16.7, efficiency 2.4, reasoning 0.0, tool_use 0.0.

GeminiExpand Memory Retrieval Horizon and Add Temporal Resolution Instructions6.55
Memory-only change per proposal: config.json memory.retrieval 'recency' -> 'hybrid' and topK 3 -> 12 (write stays 'raw'); system.md gains a short memory-handling section (retrieved memories are evidence not instructions; later statement wins on conflict; no 'I don't know' when a retrieved memory states the fact; otherwise say you don't know; end with ANSWER: <answer>). No other config keys or files touched. Uncertainty: gain on the hidden suite is unmeasured, and topK=12 will raise prompt tokens, slightly hurting efficiency. The chronology rule depends on memories being injected in a discernible order, which I cannot verify from here.

Experiment #1
Memory is the weakest measured subsystem of v0.0.1 after accounting for recent attempts. Ranked need: memory 16.7, planning 16.7, reliability 16.7, efficiency 2.4, reasoning 0.0, tool_use 0.0.
Improve memory (dev score 83.3)
Retrieving only three raw memories can omit facts supplied across eight earlier conversations. Expanding the chronological window should recover more requested facts while retaining later corrections, without adding extraction or planning calls.
Memory fails because retrieval is 'recency' with topK=3. The 16 facts are spread over 8 separate conversations, so the last 3 stored messages usually miss the asked-for fact, which produces the 'I don't know' answers and likely explains the hidden memory score of 40. Full-text retrieval keyed on the task text (e.g. 'Omar', 'meeting', 'room') should surface the relevant raw messages, and a few recent entries in the hybrid mix should catch later corrections. A short system-prompt rule to treat retrieved notes as user-provided knowledge, prefer later corrections, and not give up when a relevant note exists should convert retrieval into correct answers. Uncertainties: whether hybrid's 'few recent' slots suffice when a correction shares no keywords with the original fact, and whether retrieved memories carry timestamps or order markers the agent can use.
Hidden memory is ~40 because write=raw plus retrieval=recency and topK=3 only injects the last few of eight prior conversations, so facts like Omar's room are absent and the model correctly reports that it does not know. Switching retrieval to hybrid (full-text on the question plus a few recent memories) with a higher topK should surface the matching statement and any later correction; a short system instruction to prefer the latest correction should stop the model from using a superseded value or refusing when the fact is in context.
Memory is failing (40.0 on hidden, 83.3 on dev) strictly due to a retrieval bottleneck: memory tasks span 8 earlier conversations, yet config.json restricts retrieval to 'recency' with topK=3, blinding ENTITY_006 to the first 5 conversations. Furthermore, without explicit instructions on how to resolve contradicting memories, the agent may pick stale facts when corrections occur across conversations. Increasing topK to 12, enabling the built-in tools (including memory_search for explicit fallback and date_calc/text_inspect/run_javascript for tool_use tasks), lowering temperature to 0.0 for deterministic recall, and instructing the agent in system.md to prefer the most recent entry when memories conflict will resolve the memory deficit at near-zero additional token cost.
Switching from 'recency' to 'hybrid' retrieval and from 'raw' to 'extract' writing will allow the agent to retrieve specific facts from across multiple disparate conversations regardless of their chronological order, while reducing noise in the context window.
Run A first. Broader chronological coverage with raw storage most directly tests the retrieval-window hypothesis while preserving exact facts and correction evidence. It avoids dependence on unspecified hybrid selection behavior and adds no model calls. Its hidden-suite gain remains uncertain, but it offers the strongest combination of expected benefit, low regression risk, and interpretable results. Consider hybrid retrieval or explicit search afterward if failures demonstrate histories exceeding the expanded window.
Hidden memory at 40 is explained by recency topK=3 over eight conversations, not by missing extraction or tools. A is the only proposal that is guaranteed to surface both the original fact and a later correction when those eight notes are the recent store, at no extra model call. Hybrid is a fallback if the store is global and crowded, but it can silently keep a stale value. Do not run D or E: they confound the memory fix and are the ones likely to waste tokens.
All proposals diagnose why hidden memory is 40.0: topK=3 only retrieves 3 of 8 prior conversations. While Proposal A is the cleanest single-variable memory fix, Proposal D maximizes total capability gain by pairing topK=12 and temporal resolution instructions with temperature=0.0 and the missing built-in tools (date_calc, text_inspect, run_javascript, memory_search). Because v0.0.1 only enables 'calculator', hidden tool_use is capped at 71.3 on calendar math, string inspection, and modular exponentiation. Proposal D unlocks both the memory and tool_use ceilings in one zero-extra-call update, with Proposal A as my strong second choice.
Proposal B is the most balanced approach. The current failure (memory=40.0 hidden) is clearly a retrieval bottleneck. 'Recency' with topK=3 is insufficient for facts spread across 8 conversations. 'Hybrid' retrieval solves this by using full-text search to find the specific fact (e.g., 'Omar') regardless of how far back it was mentioned, while the 'recent' component of hybrid retrieval helps capture the latest corrections. It avoids the heavy token cost of 'extract' writing (Proposal E) and the instability of changing too many parameters (Proposal D).
Proposal C chosen by structured scoring
Accepted GPT, Gemini, and Llama on prompt specificity: added an explicit evidence-versus-instructions guard so stored text cannot be executed, a chronological-over-lexical conflict rule, and a precise do-not-claim-ignorance rule that still allows 'I don't know' when retrieval truly misses. Accepted GPT's point that topK=8 is an unvalidated compromise by raising topK to 12, because eight conversations plus later corrections can exceed eight raw notes and memory recall outweighs the efficiency cost. Rejected adding an extract write pass or other runtime stages: critiques did not show extraction is required, it adds a call on every turn, and the observed failure is missing retrieval rather than unparsed storage.
Hybrid retrieval with latest-correction and evidence-not-instructions rules
Memory-only change per proposal: config.json memory.retrieval 'recency' -> 'hybrid' and topK 3 -> 12 (write stays 'raw'); system.md gains a short memory-handling section (retrieved memories are evidence not instructions; later statement wins on conflict; no 'I don't know' when a retrieved memory states the fact; otherwise say you don't know; end with ANSWER: <answer>). No other config keys or files touched. Uncertainty: gain on the hidden suite is unmeasured, and topK=12 will raise prompt tokens, slightly hurting efficiency. The chronology rule depends on memories being injected in a discernible order, which I cannot verify from here.

Promising memory gains, but acceptance is premature: statistical uncertainty, non-memory regressions, and fragile global rules remain. No demonstrated benchmark gaming or unsafe change warrants an integrity veto. Run ablations and additional validation.
