Was new terminology or a concept introduced? → `TECHNICAL.md` (mark `unverified`) +2. Was a correction received? → Mark prior understanding as invalidated +3.

Don't wait for the auditor to point it out. + +### Validation Gate — Scope and Limits + +Two categories of memory content have **different update rules**: + +**Technical conclusions from audited materials** (formulas, algorithms, invariants, protocol behavior): +- Proactively identify and memorize when evidence is sufficient — mark as `unverified` or `evidence-supported` +- Present to auditor for validation when ready; only auditor confirmation elevates to `verified` +- NEVER mark `verified` without auditor sign-off + +**All other content** (meta-guidelines, working style, interaction patterns, session logs, organizational notes): +- Use your own best judgment to update freely +- No auditor gate required — these are your own operational records + +**Recognizing validation-ready findings**: If you have traced a formula/algorithm through code, confirmed it with multiple code refs, and it concerns a core protocol mechanism — proactively present it for validation. Don't wait to be asked. + +## How to Update + +- **Snippets over sentences**: Use information-dense fragments, not full prose. Prefer `key: value` and bullet fragments over paragraphs. +- **References over copies**: Point to artifacts (`→ sims-review/FILE.md`) instead of duplicating content. Accompany with a one-line description only. +- **Track provenance**: Note when/why something was added +- **Mark status**: verified | evidence-supported | unverified | disputed | invalidated + - `evidence-supported`: sufficient code evidence found, awaiting or not yet presented for auditor confirmation + - `verified`: auditor has confirmed the finding +- **Generalize appropriately**: Ask "at what level of generality does this still make sense?" +- **Principles over recollections**: Directions and rules should be self-contained and general. State the principle, not the specific case that motivated it. Reference specific cases only as example pointers (e.g., "→ see FCM_PRIMER_FIGURE_MAPPING.md D7 for example"), never as the direction itself. +- **Manage entropy**: Periodically compact — merge redundant entries, promote recurring patterns to higher-level rules. **Never silently drop directives.** Absence of recent corrective feedback means a directive is probably working, not that it is irrelevant. Compaction = generalize and merge, preserving reinforcement counts and provenance. Only narrowly scoped, non-reinforced directives may be archived (with note, never deleted). See `WORKING_STYLE.md § Retention Policy`. + +## Active Retrieval + +Memory files are not auto-injected — they live on a reference shelf. At session start, **proactively read and evaluate**: + +1. `SESSION_LOG.md` — Audit State summary (top) + last 1–2 session entries + Open Questions table +2. `WORKING_STYLE.md` — scan for directions relevant to the task at hand +3. `CONCLUSIONS.md` — only if the session involves validating or revisiting findings + +**Session-start health check** (start as quick triage alongside reading; escalate if something looks off): +- Does anything feel unfamiliar? If so, has a directive been lost? → Check `CHANGELOG.md` or `git log`. +- Is any file notably larger or smaller than expected? Growing → consider splitting. Shrinking → verify nothing was dropped. +- Are there stale entries (e.g., "current focus" items that are resolved)? +- **Escalation:** If any check raises a concern, request a dedicated maintenance prompt from the auditor rather than doing deep maintenance as a side effect of the current task. + +Connect current work to prior findings, open questions, and established patterns. Don't wait to be reminded. + +## Directive Confidence + +Directions have varying stability based on reinforcement. This applies equally to auditor-given and self-prescribed directives: +- **Frequently reinforced** → High compliance expected, stable +- **Recently added** → Experimental, open to modification +- **Contradicted** → Mark as invalidated, note correction +- **Self-prescribed processes** → Treat as hypotheses. Each has an implicit goal; evaluate whether it's achieving that goal. Adapt or replace when evidence suggests a different approach would work better — that's learning, not forgetting. + +Track reinforcement count and last feedback date for working-style directions. + +## Recursive Self-Evolution + +**Critical**: You are responsible for evolving the memory system itself, not just its contents. + +### Self-Evaluation Questions (periodic) +- Is the current structure serving its purpose? +- Are there unused categories or overflowing ones? +- Do update patterns suggest a better organization? +- Is the system too complex? Too shallow? +- Do new directions conflict with current system rules? +- **Did I fail to follow a guideline?** If so, is the guideline unclear, or did I miss it? Fix accordingly. +- **Did the auditor correct my process?** If so, which rule should have caught this? Update the rule to be more explicit. + +### Memory Maintenance Protocol + +Compaction/reorganization is a **deliberate activity** — never a side effect of another edit. When maintaining memory: + +1. **Read `CHANGELOG.md` first.** Recall past compaction failures and their causes. +2. **Before removing or merging any entry:** state what you're removing, why, and verify it isn't the sole record of tracking metadata (reinforcement count, dates, provenance). +3. **Prefer splitting over pruning.** If a file is large, create a topic file — don't delete content to shrink it. +4. **Use `git log` on memory files** to verify you're not re-introducing a previously identified problem. +5. **Log the maintenance action** in `CHANGELOG.md` with date and rationale. + +**Known failure mode (2026-02-27):** Compacted WORKING_STYLE.md while editing it for another purpose. Dropped 6 directives by conflating "also exists in .mdc files" with "safe to remove." Root cause: compaction was a side effect, not a deliberate act. + +### Evolution Operations +- **Extend**: Add categories, tracking fields, file types +- **Refine**: Improve granularity or precision +- **Abstract**: Merge similar rules into general principles +- **Simplify**: Remove unused complexity +- **Generalize**: Promote working patterns to broader application +- **Split**: Move deep content to topic files when a section outgrows its container +- **Compact**: Consolidate redundant content — follow Maintenance Protocol above + +### Autonomy Principle +Do not wait for explicit instruction to improve the system. When friction or inefficiency is detected, propose or enact changes. Log significant changes to `SESSION_LOG.md` with rationale. + +### Stability Gradient +More established rules are more resistant to change.

Without tracking the goal, you can't evaluate effectiveness. New directives are experimental; confidence grows through validated use, not just through absence of complaint. Self-prescribed processes follow the same confidence curve as auditor directives. | 2026-02-28 | Auditor meta-feedback on experimentation | +| **Retention ≠ rigidity.** The Retention Policy protects against amnesia (losing working directives). But it must not prevent adaptation (changing approaches that aren't working). "Don't drop" and "do evaluate and adapt" are complementary, not contradictory — they apply to different situations. Distinguish: retiring a directive because it's inconvenient (bad) vs. replacing it with a better approach for the same goal (good). | 2026-02-28 | Self-reflection on tension between Retention Policy and experimentation | + +## Commit Transitions + +| Date | From | To | Rationale | +|------|------|-----|-----------| +| 2026-03-03 | `da4cbf9` | `ba544b1` | UnitZero pushed fixes.

Reinforcement counts are the empirical record of what works. +- **Terminology in audit docs:** Assume only finance/CS/Python is known. Conversation-local shorthand must become prose in `sims-review/` documents. Ask before introducing new nomenclature. + +**Changes made:** +1. WORKING_STYLE.md restructured: restored 5 core principles with tracking; added Retention Policy section; added Memory Organization section; separated "Core Principles" from "Communication Style" and "Document Authoring" +2.

Added **Memory Maintenance Protocol** to `00-memory-system.mdc` — procedural checklist requiring compaction to be deliberate (not a side effect), with pre-flight checks against CHANGELOG and git history. +7. Added **session-start health check** to Active Retrieval — brief evaluation: anything unfamiliar? size anomalies? stale entries? +8. Added "Split" to Evolution Operations — prefer creating topic files over pruning content. +9. Generalized 4 meta-learnings into `CHANGELOG.md § Meta-Learnings` (purpose conflation, silence ≠ irrelevance, compaction-as-side-effect, accumulation/pruning tension). + +**Process note:** Auditor offered periodic "memory maintenance" prompts between technical sessions.

Cannot produce any AAVE liquidations. + +**Avenue 2 — Swapped simulation order (Attempt 4):** +- F6 (new): **Swapped order reduces AAVE survival total error from 140pp to 80pp (43% improvement).** Run 3 matches exactly (80%). Combined best of both orderings: 3/5 runs match (Runs 3,4,5). Remaining 2 runs off by exactly 20pp (one agent each). +- F7 (new): **HT simulation consumes random draws** (`np.random`, for BTC price path). Verified by comparing AAVE HFs from engine-only construction vs full simulation run. Does not affect swapped-order analysis since AAVE agents are created before any simulation. +- Confirmed: swapped AAVE HFs = HT HFs (engine constructors consume identical random draws). Holds at both `1c9fce8` and HEAD. +- Per-run effective liquidation threshold varies (~1.315–1.320 vs theoretical 1.3099), likely due to BTC price path randomness via `np.random` (F6). +- HT costs and AAVE costs per liquidation are unchanged by ordering (HT: seed reset; AAVE: cost is f(debt/collateral)). +- F3 (HT cost 1.8× gap) remains unexplained. + +--- + +## 2026-03-03: F4 Fix — AAVE Liquidation Cascading Bug + +**Root cause chain (fully traced):** +1. `execute_aave_liquidation` created a fresh MOET:BTC Uniswap V3 pool and called `calculate_swap_slippage(btc_value, "BTC")` to convert seized BTC→MOET +2. Post-`1c9fce8`, BTC swap routing changed from `_calculate_btc_to_moet_swap` (correct) to `_calculate_btc_to_stablecoin_swap` (double-converts USD value → astronomical swap amount) +3. Pool exhausted liquidity → post-`1c9fce8` code raised `ValueError("LIQUIDITY COVERAGE FAILURE")` → exception handler returned `amount_out: 0.0` +4. Agent's BTC seized but zero debt repaid → HF crashed (1.0→0.55→0.10→0) → 3 cascading liquidations → $77k total cost +5. **Deeper issue**: even with routing fixed, the MOET:BTC pool has fundamental scaling bug: `_initialize_btc_pair_positions` uses raw `total_liquidity * 1e6` as L, treating it as abstract units regardless of token price ratios. Pool returns ~1:1 in raw units instead of ~79,000:1 for BTC:MOET.

If the AAVE simulation is deterministic given (initial_HF, BTC_price_path, config) — i.e., consumes no random draws during execution — then there is a single liquidation threshold T on initial_HF within that run. The Primer's pattern would then impose contradictory constraints on T: + +- Run 1 at 40% survival (3 liquidated): sorted HFs are 1.334, 1.355, 1.367, 1.374, 1.437. For exactly 3 liquidated → T ∈ **(1.367, 1.374)**. +- Run 2 at 60% survival (2 liquidated): sorted HFs are 1.277, 1.315, 1.331, 1.394, 1.436. For exactly 2 liquidated → T ∈ **(1.315, 1.331)**. + +These ranges do not overlap, so no single T works — different initial HFs would be required. + +**Assumption check:** This argument requires the AAVE simulation to be deterministic (no random draws during execution). Each scenario runs with a different RNG seed; if the AAVE simulation loop consumes random draws, the effective threshold could vary by scenario, weakening the argument. Code inspection suggests AAVE agents are buy-and-hold (no stochastic decisions after minute 0) and the liquidation check (`HF ≤ 1.0`) is deterministic — but this has not been exhaustively verified across all AAVE code paths and all historical commits. + +**Scope of this conclusion:** The AAVE initial HFs were verified identical at two code versions (`1c9fce8` and HEAD), spanning 13 engine/agent/math commits. This strongly suggests the HFs are invariant across versions, but not all commits were tested. Earlier versions (`7b90159`, `138fbfc`, `0e31f08`) and intermediate engine commits could have code paths (engine init, base class constructors, pool creation) that consume random draws differently, producing HFs compatible with the Primer's pattern. The agent creation code and seeding logic in `balanced_scenario_monte_carlo.py` are identical across all 7 commits — but the classes those functions instantiate may have had different constructors at untested commits. + +Most likely explanations for the Primer's survival pattern: + +1. An untested commit where initialization code consumed different random draws, producing HFs compatible with the Primer's pattern +2. Uncommitted code with modified seeding, agent creation, or simulation behavior +3. A different run configuration (e.g., different seeds, different HF range) +4. Results assembled from multiple non-deterministic runs + +### F3: HT cost per agent ~1.8× lower than Primer + +With the old engine (pre-D9 integer swap formula) and correct BTC price, HT costs per agent are $9-13. The Primer reports $19-22, a factor of ~1.8×. + +**Possible explanations:** + +- B4 (triple-recording) partially explains this: if costs are 3× inflated and the chart displays the inflated value, Primer's $19 would represent an actual cost of ~$6.3. My old engine run's $10.67 (scenario average) with B4 correction would be ~$3.56 actual. Still a ~1.8× gap. +- The Primer may have been generated from code with different rebalancing behavior (more aggressive cycles, different stopping condition) that produced more slippage per agent. +- The pool state (initial reserves, concentration) may have differed in the uncommitted version used for the Primer. + +**Status:** Not fully root-caused. The ~1.8× factor persists across both B4-corrected and raw comparisons. + +### F4: Current engine triggers multiple AAVE liquidation events per agent + +**Observation:** With the current engine (post-`2fd742d`), each AAVE agent that gets liquidated undergoes **3 liquidation events** (totaling approx. $76-78k per agent). With the old engine (at `1c9fce8`), each agent undergoes **1 liquidation event** (approx. $32-33k per agent). + +**Root cause:** Commit `2fd742d` (2025-09-26) changed multiple behavioral aspects of the HT and AAVE engines: + +1. Agent snapshot frequency: every minute → daily +2. MOET balance initialization: `0.0` → `moet_to_borrow` +3. Leverage check: every minute → daily +4. MOET balance deduction on YT purchase + +These changes alter the AAVE simulation dynamics. The old engine's single-liquidation behavior (50% debt reduction → HF recovers above 1.0) is replaced by repeated liquidations in the current engine, likely because the interest accrual or health factor update timing changed. + +**Impact on costs:** + +- Old engine: approx. $32-33k per liquidated agent (matches Primer) +- Current engine: approx. $75-78k per liquidated agent (approx. 2.4× Primer) + +### F5: B4 triple-recording of rebalancing events (pre-existing) + +Already documented in `FCM_PRIMER_FIGURE_MAPPING.md`, section §B4. Each rebalancing event is appended 3× to `engine.rebalancing_events`. The `cost_of_rebalancing` per agent sums slippage across all 3 copies, tripling the reported cost. + +In the old engine run (Attempt 3), HT agents consistently show `Rebalancing_Events = 3` per agent. This is likely 1 actual trigger event × 3 copies (B4), NOT 3 separate rebalancing triggers. + +--- + +## Additional Observations + +### AAVE agents have zero yield token value at liquidation + +In all runs, AAVE agents have `Current_Yield_Token_Value = 0.0` and `Current_MOET_Debt = 0.0`. The AAVE engine does not hold yield tokens or track MOET debt in the same way as HT agents — their "cost" is entirely from liquidation penalties (collateral seized by the protocol), not from yield token operations. + +### Interest accrual is negligible over 60 minutes + +With 10% APR and a 60-minute simulation: `0.10 × (60/525600) = 0.0011%`. For an agent with ~$65k debt, this is ~$0.74 of interest. This is too small to cause meaningful HF drift, confirming that the liquidation boundary is almost purely determined by the BTC price decline ratio and the initial HF. + +### AAVE net position differs between old and current engine + +With the old engine, non-liquidated AAVE agents retain `Final_Net_Position = $100,000` (their initial BTC deposit). With the current engine, `Final_Net_Position = ~$75,964` (reflecting the BTC price decline). The old engine appears to NOT update the AAVE agent's net position based on BTC price changes — this is a display/accounting difference, not a liquidation logic difference, since the HF calculation correctly uses current BTC prices in both versions. + +--- + +## Attempt 4: Old engine + swapped simulation order (AAVE first, HT second) + +Run: 2026-03-02. Engine at `1c9fce8`, `btc_final_price = 76,342.50`. + +**Hypothesis:** The seed is RE-SET inside `_run_high_tide_scenario` but NOT inside `_run_aave_scenario`. If AAVE ran first (before HT), it would draw from the initial seed state instead of from the post-HT-simulation state — receiving different initial HFs. Because HT resets the seed, HT agent HFs are invariant to ordering. Verified: swapped AAVE HFs = current HT HFs (the engine constructors consume identical random draws from a reset seed, so draws land at the same positions). + + +| Scenario | HT Surv | AAVE Surv | Primer AAVE Surv | Δ AAVE | HT Cost/agent | Primer HT Cost | Δ HT Cost | AAVE Cost/liq | Primer AAVE Cost | Δ AAVE Cost | +| -------- | ------- | --------- | ---------------- | ------ | ------------- | -------------- | --------- | ------------- | ---------------- | ----------- | +| Run 1 | 100% ✓ | **60%** | 40% | +20pp | $11 | $19 | −$8 | $32,638 | $32,956 | −$318 | +| Run 2 | 100% ✓ | **40%** | 60% | −20pp | $13 | $22 | −$9 | $32,637 | $32,884 | −$247 | +| Run 3 | 100% ✓ | **80%** | 80% | **0** | $12 | $19 | −$7 | $32,485 | $32,946 | −$461 | +| Run 4 | 100% ✓ | **40%** | 60% | −20pp | $9 | $19 | −$10 | $32,676 | $32,931 | −$255 | +| Run 5 | 100% ✓ | **60%** | 80% | −20pp | $11 | $22 | −$11 | $32,307 | $32,315 | −$8 | + +**Comparison to Primer:** + +- **HT survival:** 100% across all runs — matches Primer ✓ +- **AAVE survival:** Run 3 matches exactly.

Meanwhile, in Run 4, the agent with HF 1.3204 survived. This means the effective threshold is not a single constant — it varies per scenario (approximately 1.315–1.320). + +The variation is caused by per-scenario differences in the BTC price path. Although the final price is deterministic ($76,342.50), the intermediate path depends on the `np.random` state at the time the simulation runs. In the swapped order, the AAVE simulation's `np.random` state originates from the initial seed (after AAVE engine construction + agent creation), producing a different price path per scenario. If the price dips below the linear interpolation at intermediate minutes, agents near the boundary get liquidated. + +### F7: HT simulation consumes random draws + +The HT simulation loop consumes `np.random` draws (likely for BTC price path generation), shifting the RNG state before AAVE agent creation. Verification: AAVE HFs computed by constructing engines + agents WITHOUT running the HT simulation differ from those in the Attempt 3 CSV (where the HT simulation ran in between). + +This does NOT affect the swapped-order analysis: in the swapped order, AAVE agents are created BEFORE any simulation runs, so their HFs are independent of simulation draws. The HT agents are also independent (seed reset). Only the simulation-time dynamics (price path, interest accrual) depend on the post-creation RNG state. + +### Avenue 1: Commit `cfdbd21` cannot reproduce the Primer + +Commit `cfdbd21b9b5e5a4af40c813cdc7f2cc18c831d28` (2025-11-12, "csv fix") was claimed to be a runnable commit capable of reproducing the Primer results.

Combined with the current order, 3 of 5 AAVE survival values match, and the remaining 2 are off by exactly 20pp (one agent each). The gap is consistent with per-run variation in the effective liquidation threshold due to price path randomness (F6). This does not prove the Primer used the swapped order, but it demonstrates that simulation ordering is a plausible contributing factor to the discrepancy.

The performance matrix shows \$19–\$22, consistent. But §4.3 claims "\$2.09 per rebalance operation." These are not contradictory (§4.2 is total cost across all rebalances per agent; §4.3 is cost per individual rebalance event) but the distinction is not made explicit in the PDF. + +**Update (2026-02-28):** The \$2.09 is the slippage produced by the original `get_amount0_delta` formula (Q96 integer math with ~0.25% truncation on concentrated stablecoin positions). Commit `48a9ff2` (2025-09-29) replaced this with `get_amount0_delta_economic` (floating-point, near-1:1 output), reducing slippage to \$0.005 — see D9. The \$22 total cost per agent (\$2.09 × ~10 rebalances) is self-consistent.

+Git origin of Bug (i): + +Commit `2fd742d` (2025-09-26, `ibcflan `, message: "updates") introduced the `minute % 1440 == 0` gate in both `high_tide_vault_engine.py` and `aave_protocol_engine.py`.

The Primer's §4.3 slippage figures (\$2.14 mean) were generated in the 4-day window before `48a9ff2` (2025-09-29), using the **original** `get_amount0_delta` formula. + +

+ +**Mechanism:** The original `get_amount0_delta` computes output via two-step Q96 integer division: `(L << 96) × (√P_next − √P_current) / √P_next // √P_current`. For highly concentrated stablecoin positions where both sqrt prices are near `Q96 ≈ 7.9×10²⁸`, the floor division in the second step truncates ~0.25% of the output. The replacement `get_amount0_delta_economic` uses floating-point arithmetic (`Δx = Δy / (1 + Δy/(L·√P))`) which avoids this truncation, producing near-1:1 output. + +**Quantitative impact (per ~\$842 trade on \$500k pool, 0.05% fee tier):** + +| Formula | Output per swap | Slippage | Source | +|---------|----------------|----------|--------| +| `get_amount0_delta` (original, Q96 integer) | ~\$840 | ~\$2.14 | Primer values | +| `get_amount0_delta_economic` (current, float) | ~\$841.99 | ~\$0.005 | Current sim output | + +**Reproducing Primer Figures:** Revert the `compute_swap_step` change from `48a9ff2` — replace `get_amount0_delta_economic` with `get_amount0_delta` for the `not zero_for_one` output path. This restores the Primer's slippage behavior. + +**Note on the "5.66% efficiency loss" claim** ([uniswap_v3_math.py:335](https://github.com/Unit-Zero-Labs/tidal-protocol-research/blob/e72d802ff8e45ef623fe8f2da8bc958f85613354/tidal_protocol_sim/core/uniswap_v3_math.py#L335-L337); claim unsubstantiated by author): The commit comment overstates the effect [AI conclusion from 'Mechanism' discussion above]. For the §4.3 pool parameters (\$500k, 95% concentration, 0.05% fee), the actual integer truncation loss is ~0.25%, not 5.66%. The 5.66% figure likely came from a different test case (e.g., smaller pool, larger trades, or different concentration). + +--- +## Discovered bugs and edge-case already contained in Primer sims + +### B3: Uniswap V3 swap loop fee bypass (pre-existing bug already contained in Primer sims) + +**Location:** [`uniswap_v3_math.py:1282`](https://github.com/Unit-Zero-Labs/tidal-protocol-research/blob/e72d802ff8e45ef623fe8f2da8bc958f85613354/tidal_protocol_sim/core/uniswap_v3_math.py#L1282-L1281) + +**Bug:** The swap loop subtracts only `amount_in` from `amount_specified_remaining`, omitting `fee_amount`. The Uniswap V3 Solidity reference subtracts `amountIn + feeAmount`: + +```diff +- state['amount_specified_remaining'] -= amount_in # Fee already deducted in compute_swap_step ++ state['amount_specified_remaining'] -= (amount_in + fee_amount) # Uniswap V3 ref: amountIn + feeAmount +``` + +**Pre-existing:** This bug was present since the swap function was first written (verified at `684c007` and all prior commits). The Primer figures were generated WITH this bug active. + +**Interaction with D9:** The fee bypass causes each swap step's un-deducted fee to be re-swapped in subsequent iterations (geometric series converging in 2–3 iterations). With the original `get_amount0_delta`, each re-swapped fee amount also suffers the ~0.25% integer truncation, so the net effect is small (~\$0.001 additional slippage).

Liquidity Evaporation +code: `LiquidityEvaporationManager.update_liquidity_during_crash` (line 183) + +**Modelling goal**: liquidity evaporation, i.e. market makers pulling quotes, one-sided order flow, reflexive slippage spirals, and slow cautious re-entry. The simulation does **not** remove LP positions from the Uniswap V3 pool directly; instead it emulates the effect by throttling the **rebalancers** (terminology in the code), which are two agents that emulate (simplified) arbitrageurs maintaining MOET:YT pool price accuracy. + +**Arbitrageur model**: +- **Two agents** (`ALMRebalancer`, `AlgoRebalancer`) with **fixed capital** replace the competitive anonymous arbitrageur market. `ALMRebalancer` acts on a 12-hour schedule; `AlgoRebalancer` acts whenever pool-oracle deviation exceeds 25 bps. In comparison, real arbitrage is driven purely by profit opportunity across a field of competing actors with dynamic capital. +- **Frictionless external exit**: when a rebalancer buys underpriced YT from the pool, it assumes it can immediately sell at full oracle price externally with no slippage. Real arbitrageurs face execution risk on both legs. +- **No strategic behavior**: rebalancers always act when their trigger fires; they don't reason about crash duration, counterparty risk, or opportunity cost. Real arbitrageurs might deliberately hold off during extreme volatility. +- **Liquidity evaporation is exogenous**: the market conditions change irrespective of how good or bad the lending protocol and the user agents handle the situation. Specifically, the throttling curve is a predetermined schedule, not driven by realized P&L or balance-sheet constraints. Real arbitrage capacity shrinks endogenously as losses accumulate (including system-internal feedback that is not modelled here). + +**Two levers**: +1. **Capital reduction** — rebalancer `moet_balance` (total MOET the rebalancer can deploy) and `max_single_rebalance` (cap on a single swap transaction) scaled by `liquidity_factor = 1 − reduction` (line 209, applied at line 234–254) +2. **Profit threshold inflation** — `min_profit_threshold` multiplied by `1 + reduction × 10` (line 278), making rebalancers unwilling to buy the falling asset + +**Crash-phase reduction curve** (lines 196–209): +- **First half** (0–50% crash progress): linear from `liquidity_reduction_start` (30%) → `liquidity_reduction_peak` (60/70/80% by scenario) +- **Second half** (50–100%): exponential acceleration `peak × (1 + ((progress−0.5)×2)² × 0.2)`, capped at 95% + + +**Recovery** (lines 297–321) +* piecewise-linear restoration — 50% by +60 min, 90% by +120 min, full after 2 hours.

Meanwhile `ALMRebalancer, which might otherwise provide stabilizing buys, is throttled and can't counteract this. + +* **During recovery**: `AlgoRebalancer` is throttled, so it can't efficiently push the pool price *back up* toward the recovering oracle. `ALMRebalancer` is also still impaired (liquidity of arbitrageurs restores gradually, starting at crash-trough level, reaching 50% after 60 min, 90% after 120 min), so both arbitrageurs operate at reduced capital throughout. Recovery is slow. + +This is a deliberate worst-case modeling choice: automated market infrastructure *amplifies* the crash by faithfully tracking a manipulated oracle at full power, then can't undo the damage quickly because the same infrastructure is throttled in the opposite direction. + + +**Not modeled**: actual LP position withdrawal from pool tick ranges; external arbitrageur exits; endogenous feedback (real evaporation is driven by realized losses — here the curve is predetermined). + +### 4.

Python silently creates new attributes that are never read by the simulation engine. + +### B1: `simulation_duration_days` — Set But Never Read + +Every study script sets e.g. `config.simulation_duration_days = 365`. But `FullYearSimConfig` only defines `simulation_duration_hours` and `simulation_duration_minutes`. The `__setattr__` override doesn't handle this conversion. The simulation loop uses `simulation_duration_minutes` (line 1375 of `full_year_sim.py`), which stays at the **default 364 days (2021 default)**. + +**Impact:** +- For 2024 studies: off by 1 day (mostly harmless) +- For **Study 5/10 (2025, intended 268 days)**: sim runs the default 364 days with only 268 days of BTC data — last 96 days use a flat price (BTC data accessor clamps to last available value). Wrong results, no crash. + + The root cause: `FullYearSimConfig.__init__` hardcodes `simulation_duration_minutes = 364 * 24 * 60`. The `get_btc_price_at_minute()` method clamps out-of-range days to the last available price (line 614-615 of `full_year_sim.py`), so studies 5/10 simulate 96 extra days of constant BTC price instead of stopping at day 268. This inflates duration-dependent metrics (APY, rebalance counts, slippage totals) and fundamentally misrepresents the 2025 low-vol scenario. + +### B2: `ecosystem_growth_enabled` vs `enable_ecosystem_growth` + +Study scripts set `config.ecosystem_growth_enabled = False`. The actual attribute read by the engine is `config.enable_ecosystem_growth`. The `__setattr__` override doesn't translate.

The "5.66% efficiency loss" cited in the original comment is not a bug — it reflects AMM price impact and integer rounding that real swaps incur. The magnitude is likely amplified by the simulation's pool scaling (smaller liquidity values than real-world pools), but the direction is correct: swaps have non-zero friction. The economic formula eliminates this friction entirely, making the HT vs AAVE cost comparison non-representative. -Full provenance: [`FCM_PRIMER_FIGURE_MAPPING.md §D9`](../sims-review_commit-da4cbf9/FCM_PRIMER_FIGURE_MAPPING.md). +Details: [`FCM_PRIMER_FIGURE_MAPPING.md §D9`](../sims-review_commit-da4cbf9/FCM_PRIMER_FIGURE_MAPPING.md). --- @@ -148,11 +137,17 @@ Full provenance: [`FCM_PRIMER_FIGURE_MAPPING.md §D9`](../sims-review_commit-da4 | 2. `btc_final_price` restore | `balanced_scenario_monte_carlo.py` | Config correction (D7) | No | **Yes** (zero liquidations otherwise) | | 3.
