feat: smart patch, dep stubs, progress log, docker fix

Benchmark improvements (Run 3: 27.3% -> 54.5% reproducibility):
- applyPatchSmart: fix critical patch application bug (specificity was 0%)
Previously cp -rv copied wrong directory level, patch was never applied
Now strips 1-3 path prefix levels to match files correctly
- computePatchDiff: correct diff using same strip-depth matching logic
- dependencyStubber.ts: pre-forge probe creates stubs for missing deps
Targets 7 failing cases using lib/caviar or node_modules imports
- projectContextExtractor.ts: BFS test file selection + remappings context
- compileFailures counter + MINIMAL_INTERFACE escape at 3 failures
- Patch diff shown in analyzeVulnerabilityNode for specific assertions
- Improved prompts: reentrancy receive() pattern, unchecked return pattern
- Error lines surfaced in fix prompt for faster compiler error resolution

Docker / integration:
- setup-sandbox.sh: source ~/.foundry/env for non-interactive shells
Fixes case 046 (forge not in PATH in Docker)
Fallback: checks ~/.foundry/bin/forge directly before failing

+# PoC Tester Agent — Progress Log
+
+> **Repository:** `uandersonricardo/projeto-talp1`
+> **Branch:** `teste_agent`
+> **Model used:** `google/gemini-3.1-flash-lite` (via OpenRouter)
+> **Framework:** LangGraph + Foundry
+> **Dataset:** [ASSERT-KTH/Proof-of-Patch](https://github.com/ASSERT-KTH/Proof-of-Patch) — 22 real-world smart contract vulnerabilities with verified patches
+
+---
+
+## Metric Definitions
+
+| Metric | Formula | Meaning |
+|---|---|---|
+| **Reproducibility Rate** | `PoCs passing on vulnerable version / 22` | Agent generates a working exploit |
+| **Specificity Rate** | `PoCs failing on patched version / reproducible PoCs` | Exploit is logically correct (patch stops it) |
+| **Overall Ground Truth** | `reproducible AND specific / 22` | Both conditions satisfied |
+
+> **Reference:** The PoCo paper (Andersson et al., arXiv:2511.02780) evaluated on the same dataset using GPT-4o.
+> Cases #003 and #015 have "inconclusive patches" per §5.3.1 — the patch fixes the bug but the PoC still passes because it tests side-effects unaffected by the fix. This is a known dataset limitation.

+## Benchmark History
+
+### Run 0 — Baseline (before any improvements)
+**Date:** 2026-06-07 (pre-session)
+**Commit:** `d849e68`
+
+| Metric | Value |
+|---|---|
+| Reproducibility | **27.3%** (6/22) |
+| Specificity | **0.0%** (0/6) |
+| Overall Ground Truth | **0.0%** |
+| Avg Iterations | 8.18 |
+
+**Reproducible:** 001, 003, 008, 051, 054, 091
+**Main failure:** ~63% were COMPILER_ERROR — agent guessing wrong import paths with no context.
+
+---
+
+### Run 1 — Quick validation (5 cases, first improvements)
+**Date:** 2026-06-08
+
+| Metric | Value |
+|---|---|
+| Reproducibility | **20.0%** (1/5) |
+| Specificity | **0.0%** |
+| Avg Iterations | 8.40 |
+
+---
+
+### Run 2 — Quick validation (5 cases, BFS + minimal interface)
+**Date:** 2026-06-08
+**Key changes:** BFS test file selection, compileFailures counter, MINIMAL_INTERFACE escape hatch
+
+| Metric | Value |
+|---|---|
+| Reproducibility | **80.0%** (4/5) |
+| Specificity | **0.0%** |
+| Avg Iterations | 7.00 |
+
+**Notable:** Case 015: 10 iters → failed became 6 iters → success thanks to MINIMAL_INTERFACE.
+
+---
+
+### Run 3 — Full benchmark (22 cases)
+**Date:** 2026-06-08
+**Commit:** `1929f1b`
+
+| Metric | Value |
+|---|---|
+| Reproducibility | **54.5%** (12/22) |
+| Specificity | **0.0%** (0/12) |
+| Overall Ground Truth | **0.0%** |
+| Avg Iterations | 7.55 |
+
+**Reproducible (12):** 001, 003, 008, 015, 032, 051, 054, 058, 066, 077, 091, 098
+**Failed (10):** 009, 018, 020, 033, 039, 041, 042, 048, 049, 070
+**Error (1):** 046 (forge not in PATH during setup)
+
+**Root cause of specificity=0%:** Patch application was broken — `cp -rv patches/ID/*` copied
+a repo-name subdirectory INTO tempPatchDir instead of overwriting the actual source files.
+The "patched" version was still running the vulnerable code.

+
+## Improvements Implemented
+
+### 1. `projectContextExtractor.ts` (NEW)
+**Problem:** LLM was guessing import paths → 63% COMPILER_ERROR failures.
+**Fix:** Before generating PoC, reads `remappings.txt`, `foundry.toml`, and the most import-rich
+`.t.sol` test file (BFS across all subdirs, picks file with most import lines).
+
+### 2. `compileFailures` Counter + MINIMAL_INTERFACE Escape Hatch
+**Problem:** After 10 failed compile attempts, LLM stuck in loop on wrong imports.
+**Fix:** Counter increments per compile failure. After 3 consecutive → switches to
+`POC_MINIMAL_INTERFACE_PROMPT` which forbids all external imports and uses inline interfaces.
+
+### 3. Error Context in Fix Prompt
+**Problem:** LLM only saw "Import path is WRONG" — not which file.
+**Fix:** `analyzeFoundryLog` extracts actual error lines (file path + line number) and surfaces
+them at the top of the fix prompt.
+
+### 4. Patch Diff in Analysis Prompt
+**Problem:** LLM generating generic assertions passing on both vulnerable and patched versions.
+**Fix:** Patch diff (unified diff of vulnerable vs patched contract) included in
+`analyzeVulnerabilityNode` with instruction: "assertion must PASS on vulnerable, FAIL on patched."
+
+### 5. `dependencyStubber.ts` (NEW)
+**Problem:** 7 cases fail because `lib/caviar/lib/oracle/...` or `node_modules/@openzeppelin/...`
+are absent from the sandbox.
+**Fix:** Runs `forge build` probe before generation, detects all "Source not found" errors,
+creates minimal stub contracts at those exact paths.
+
+### 6. `applyPatchSmart` — Smart Patch Application (CRITICAL for specificity)
+**Problem:** `cp -rv patches/ID/*` was copying a repo-name subdirectory INTO `tempPatchDir`.
+The "patched" test was running the vulnerable code. This is why specificity was always 0%.
+**Fix:** For each `.sol` in the patch dir, strips 1, 2, then 3 path prefix levels to find
+matching file in `tempPatchDir` and copies it correctly.
+
+```
+Patch file: patches/003/2023-07-pooltogether/vault/src/Vault.sol
+tempPatchDir: copy of findings/003/2023-07-pooltogether/vault/
+
+strip=1: vault/src/Vault.sol → NOT in tempPatchDir
+strip=2: src/Vault.sol → EXISTS ✅ → copy applied
+```
+
+### 7. `computePatchDiff` — Correct Diff Calculation
+**Problem:** Previous diff command tried a hardcoded path that didn't match the nested structure.
+**Fix:** Uses same strip-depth logic as `applyPatchSmart` to find the right file pair.
+
+### 8. Improved Prompts
+- `ANALYZE_VULNERABILITY_PROMPT`: asks for specific assertion that fails after patching
+- `POC_COMPILE_FIX_PROMPT`: import resolution hierarchy (remappings → existing test → inline)
+- `POC_TEST_FIX_PROMPT`: added reentrancy `receive()` callback pattern + unchecked return pattern
+- `POC_MINIMAL_INTERFACE_PROMPT` (NEW): full template for zero-external-import strategy

+
+## Next Steps
+
+### P0 — Run benchmark with patch fix + dep stubs (Run 4)
+Expected: Reproducibility ~68%, Specificity ~30%, Ground Truth ~20%
+
+### P1 — Add `refineSpecificityNode`
+If PoC passes on both versions, run a refinement step:
+- Show: current PoC + patch diff
+- Ask: "Make the assertion target exactly what the patch changes"
+
+### P2 — Docker update
+The Dockerfile builds TypeScript, so new files are included automatically.
+Fix needed: `setup-sandbox.sh` may not find `forge` in Docker because foundryup
+sets PATH in `~/.bashrc` (not sourced in non-interactive shells). Fix: add
+`source ~/.foundry/env` or `export PATH="$HOME/.foundry/bin:$PATH"` explicitly.
+
+### P3 — Integration check
+The tester agent's public API (`VulnerabilityReport → { status, solidityCode }`) is unchanged.
+The server.ts route calling `runPoCGenerator()` still works.
+Docker image needs rebuild after code changes.

+| Specificity | 0.0% | ~30% |
+| Overall Ground Truth | 0.0% | ~20% |

+## CRITICAL IMPORT RULES
+- You MUST use the project's own import paths (see "Project Remappings" and "Import Pattern from Existing Test" if provided).
+- If remappings are provided (e.g., \`@openzeppelin/=lib/openzeppelin-contracts/\`), use them exactly as listed.
+- If an existing test shows \`import {Foo} from "project/Foo.sol"\`, follow that exact pattern.
+- If you are NOT sure about the import path for an external dependency, AVOID importing it. Use a minimal interface or mock instead.
+- The contract under test is already in the sandbox — use a relative import like \`import { ContractName } from "../src/ContractName.sol"\` unless remappings say otherwise.
 
-## REGRAS DE QUALIDADE
-- A asserção final DEVE provar a vulnerabilidade.
-- Use o mesmo estilo de imports e setup dos contratos de referência fornecidos.
-- Output APENAS um bloco \`\`\`solidity ... \`\`\` com o arquivo completo.
+## QUALITY RULES
+- The final assertion MUST prove the vulnerability. It should use assertEq, assertGt, assertLt, assertGe, assertLe, or assertNotEq with meaningful values.
+- NEVER write \`assertTrue(true)\` or \`assert(true)\`. This is an automatic failure.
+- The assertion must be specific enough that it would FAIL on a patched version of the contract.
+- Output ONLY a single \`\`\`solidity ... \`\`\` block with the complete file.
+
+## FALLBACK STRATEGY
+If the contract has complex dependencies that are hard to mock, use this minimal approach:
+1. Declare a minimal interface for the contract with only the functions you need.
+2. Deploy the real contract by importing it directly (relative path).
+3. Call the vulnerable function directly without complex setup.
+`.trim();
+
+export const POC_COMPILE_FIX_PROMPT = `The previous PoC test FAILED TO COMPILE. You must fix ALL compilation errors and return the complete corrected file.
+
+## IMPORT ERROR STRATEGY (most common fix)
+If the error is about a missing source file or identifier not found:
+1. Check the "Project Remappings" provided — use those exact paths.
+2. Check the "Import Pattern from Existing Test" — copy those import statements exactly.
+3. If you cannot find the right import path, REMOVE that import and replace it with a minimal interface:
+   \`\`\`solidity
+   interface IERC20 { function transfer(address to, uint256 amount) external returns (bool); }
+   \`\`\`
+4. NEVER guess an import path. Only use paths you can verify from the remappings or existing test.
+
+## OTHER COMPILATION FIXES
+- Missing type members: declare a minimal struct/interface instead of importing the full library.
+- Visibility errors: check that you're calling public/external functions only.
+- Type mismatches: cast explicitly (e.g., \`uint256(value)\`, \`address(contract)\`).
+- ABI encoding errors: use \`abi.encodeWithSelector(Contract.func.selector, args)\`.

+export const POC_TEST_FIX_PROMPT = `The PoC compiled successfully but FAILED DURING EXECUTION (revert or assertion failure). Fix the test logic.
+
+## REVERT DIAGNOSIS
+If the test reverted without a message:
+1. The call order may be wrong — check what preconditions the contract requires.
+2. A role/permission may be missing — use \`vm.prank(owner)\` to set up roles first.
+3. The contract may need funding — use \`vm.deal(address(contract), amount)\`.
+4. A previous transaction may have changed state — check ordering carefully.
+5. **"call to non-contract address"**: The contract was not deployed yet — you must deploy it in setUp() first.
+
+## ASSERTION FAILURE DIAGNOSIS
+If the assertion failed (values didn't match expected):
+1. The exploit logic is incorrect — re-read the vulnerability description carefully.
+2. The vulnerable code path may not be reached — trace with intermediate assertions.
+3. The assertion values may be wrong — recalculate what the expected outcome should be.
+
+## REENTRANCY PATTERN
+If testing a reentrancy vulnerability, add a callback to ExploitTest:
+\`\`\`solidity
+uint256 public reentrancyCount;
+uint256 public stolenAmount;
+
+receive() external payable {
+    if (reentrancyCount < 3 && address(target).balance > 0) {
+        reentrancyCount++;
+        target.withdraw(/* same amount */);
+    }
+    stolenAmount += msg.value;
+}
+\`\`\`
+Then assert: \`assertGt(stolenAmount, initialDeposit, "Reentrancy drained more than deposited")\`
 
-Focus strictly on:
-- Fixing import statements and dependencies.
-- Correcting Solidity syntax errors or missing members.
-- Ensuring proper contract instantiation and function signatures.
-- Resolving visibility issues.
+## UNCHECKED RETURN VALUE PATTERN
+If testing unchecked external call return values:
+\`\`\`solidity
+// The contract ignores the return value of an external call
+// You can demonstrate by causing the call to fail while the contract still proceeds
+bool callSucceeded = target.doExternalCall(params);
+// If the vulnerability is that a false return is ignored:
+assertFalse(callSucceeded, "External call returned false but was ignored");
+// Or show the state changed incorrectly:
+assertEq(target.state(), wrongValue, "State updated despite failed external call");
+\`\`\`
 
-Return the FULL corrected Solidity file in a \`\`\`solidity\`\`\` block.
+## MINIMAL VIABLE EXPLOIT RULE
+If after 2+ failed attempts you cannot get the full exploit to work:
+- Simplify to the most minimal version that demonstrates the bug.
+- A partial demonstration (e.g., wrong state, unauthorized access) is better than nothing.
+- Focus on the ASSERTION — it must prove the vulnerability exists.
+
+## STRICT RULE
+Return the FULL corrected Solidity file in a \`\`\`solidity\`\`\` block. Fix ALL errors in one pass.

+
+## MANDATORY RULES — READ CAREFULLY
+1. **REMOVE ALL EXTERNAL IMPORTS** — Do NOT import any library or contract except \`forge-std/Test.sol\`.
+2. **DECLARE EVERYTHING INLINE** — Declare minimal interfaces for every external type you need:

+    function approve(address spender, uint256 amount) external returns (bool);
+    function balanceOf(address account) external view returns (uint256);
+}
+\`\`\`
+
+3. **USE address() CASTS** — If you need a contract type, cast from address: \`ITargetContract(contractAddress)\`
+4. **DEPLOY WITH low-level calls if needed** — If you cannot import the contract, use \`address(new bytes(code))\` or \`ITargetContract(deployedAddress)\`
+5. **THE CONTRACT UNDER TEST IS AT A RELATIVE PATH** — If you must import it, use ONLY: \`import "../src/ContractName.sol"\` (the only safe import besides forge-std)
