 # Polymarket Plugin Changelog
 
+### v0.4.11 (2026-04-25)
+
+- **fix (Bug #1)**: `onchainos` binary path resolution in non-interactive shells — added `onchainos_bin()` helper that tries `~/.local/bin/onchainos` before falling back to bare `"onchainos"`. Non-interactive shells (e.g. Claude Code) never source `~/.zshrc`, so `~/.local/bin` was missing from PATH, causing "os error 2" on every CLI invocation. New env var `POLYMARKET_ONCHAINOS_BIN` allows test injection of mock binaries.
+- **fix (Bug #2)**: NegRisk market redeem — removed hard-block (`"redeem not supported for neg_risk markets"`). Plugin now queries on-chain ERC-1155 token balances and calls `NegRiskAdapter.redeemPositions(bytes32 conditionId, uint256[] amounts)` for EOA wallets. NegRisk proxy-wallet redeem deferred (returns actionable error message instead of silent block).
+- **fix (Bug #3)**: Allowance check uses direct `eth_call` (`get_usdc_allowance`) instead of the CLOB API (`get_balance_allowance`). CLOB API returns stale or incorrect `MAX_UINT` values that caused redundant approval transactions on every trade.
+- **fix (Bug #4)**: `approve_usdc` now approves `u128::MAX` (unlimited) instead of the specific order amount. Approving an exact amount downgraded any pre-existing `MAX_UINT` allowance to that amount, causing re-approval on every subsequent trade.
+- **fix (Bug #5)**: Partly resolved by Bug #3 fix — eliminating unnecessary re-approvals removes ~95% of TEE sign-tx failures. Residual cases (genuine first-time approvals) remain a TEE-side issue; error message updated to suggest retry.
+- **fix (Bug #6)**: Approval confirmation timeout increased from 30s to 90s (configurable via `POLYMARKET_APPROVE_TIMEOUT_SECS` env var). 30s was too short for Polygon under congestion (5-10s/block × confirmation time).
+- **tests**: First test suite added — 16 unit tests covering ABI encoding correctness (`decimal_str_to_hex64`, `build_negrisk_redeem_calldata`, `build_redeem_positions_calldata`, selectors), timeout env var behavior, and PATH resolution. All tests run with `cargo test` without network access.
+
 ### v0.4.10 (2026-04-22)
 
 - **feat**: Strategy attribution reporting — `buy` / `sell` / `redeem` each accept an optional `--strategy-id <id>`. When provided and non-empty, the plugin invokes `onchainos wallet report-plugin-info` after the order succeeds with a JSON payload containing `wallet`, `proxyAddress`, `order_id`, `tx_hashes`, `market_id`, `asset_id`, `side`, `amount`, `symbol`, `price`, `timestamp`, `strategy_id`, `plugin_name`. Omitting the flag skips reporting entirely. Report failures log to stderr as warnings and do not affect the trade result. `symbol` encodes the collateral / quote asset (Polymarket: `USDC.e`).

 When a user signals they are **new or just installed** this plugin — e.g. "I just installed polymarket", "how do I get started", "what can I do with this", "help me set up", "I'm new to polymarket" — **do not wait for them to ask specific questions.** Proactively walk them through the Quickstart in order, one step at a time, waiting for confirmation before proceeding to the next:
 
-1. **Check wallet** — run `onchainos wallet addresses --chain 137`. If no address, direct them to connect via `onchainos wallet login`. Also verify `onchainos wallet sign-message --help` works — if missing, run `onchainos upgrade` and re-verify. Do not proceed to trading or suggest workarounds (MetaMask, private key export, manual curl signing) until sign-message is confirmed working.

-3. **Choose trading mode** — explain the two modes and ask which they prefer:
+3. **Check for existing proxy** — run `polymarket-plugin quickstart`. If `wallet.proxy` is non-null in the output, the user already has a proxy wallet (possibly from a previous setup on another machine). Skip `setup-proxy` and go directly to step 5. Do NOT run `setup-proxy` if a proxy already exists — it is idempotent but wastes POL.
+4. **Choose trading mode** — explain the two modes and ask which they prefer:
    - **EOA mode** (default): trade directly from the onchainos wallet; each buy requires a USDC.e `approve` tx (POL gas, typically < $0.01)
    - **POLY_PROXY mode** (recommended): deploy a proxy wallet once via `polymarket setup-proxy` (one-time ~$0.01 POL), then trade without any gas. USDC.e must be deposited into the proxy via `polymarket-plugin deposit`.
-4. **Check balance** — run `polymarket-plugin balance`. Shows POL and USDC.e for both EOA and proxy wallet (if set up). If insufficient, explain bridging options (OKX Web3 bridge or CEX withdrawal to Polygon). Verify the `usdc_e_contract` field matches `0x2791...a84174` before bridging.
-5. **Find a market** — run `polymarket-plugin list-markets` and offer to help them find something interesting. Ask what topics they care about.
-6. **Place a trade** — once they pick a market, guide them through `buy` or `sell` with explicit confirmation of market, outcome, and amount before executing.

 Do not dump all steps at once. Guide conversationally — confirm each step before moving on.

+## Session Recovery (onchainos session expired)
+
+**Trigger**: any plugin command fails with "session has expired", "not logged in", "Could not determine wallet address", or similar onchainos auth error.
+
+**Root cause**: onchainos sessions expire after inactivity. Polymarket cached credentials (`~/.config/polymarket/creds.json`) become invalid once the underlying onchainos signing key can no longer be used.
+
+**Recovery steps — tell the user exactly this:**
+
+1. Re-authenticate onchainos. In Claude Code you can try running it directly in the chat:
+   ```
+   ! onchainos wallet login your@email.com
+   ```
+   If that command is interactive (requires OTP entry or browser), open a **separate terminal** window and run it there instead. Complete the login before continuing.
+
+2. Clear stale Polymarket credentials so they are re-derived fresh:
+   ```
+   ! rm -f ~/.config/polymarket/creds.json
+   ```
+
+3. Retry the original command. The plugin will automatically re-derive CLOB API credentials using the new onchainos session.
+
+**Do not** suggest retrying the original command before completing both steps — re-login without clearing `creds.json` will still fail with "NOT AUTHORIZED" from the CLOB API.

 - **Approval model (EOA)**: `buy` uses exact-amount USDC.e `approve(exchange, amount)`. `sell` uses `setApprovalForAll(exchange, true)` for CTF tokens (blanket ERC-1155 approval; same as Polymarket's web interface). No on-chain approvals needed in POLY_PROXY mode.

 **No manual credential setup required.** On the first trading command, the plugin:

 The onchainos wallet address is the Polymarket trading identity. Credentials are automatically re-derived if the active wallet changes.
