From 4622502796a29cb89d157d55c7cb1b15f02a2c0e Mon Sep 17 00:00:00 2001 From: Xore Date: Mon, 28 Sep 2026 02:03:52 +0200 Subject: [PATCH 1/2] test(ghidra): pin the Tier B loader to real Ghidra output, not a mock shaped like it Every Tier B test in the tree synthesises its own cache entry -- test_record_baseline.py builds its decompiled map inline, and test_ghidra_cache.py hand-writes its entries -- so they agree with whatever load_tier_b_evidence() happens to expect. A drift in the real service's response shape (the `pseudocode` key, the `s` key on a string, the decompiled map's value type) would pass CI against a mock that had been updated along with the code. The fixture is real recorded Ghidra output: the Tier B transcript for process_and_injection from run 20260825T190415Z-39f27b7b, the highest-risk case in the issue because it carries the injection payload. It keeps the artefacts real Ghidra produces on a relocatable .o and a hand-written fixture would not -- halt_baddata(), "Unknown calling convention", __pid_t _Var1 -- which is what makes it a fidelity check rather than a second mock. cache_key/ghidra_version/ post_scripts_sha256 are null because the recording predates keyed Tier B caching; the transcript's own reproducibility.ghidra_cache_key is null too. Round trip, byte-exact: the fixture written back as a cache entry -> load_tier_b_evidence() -> build_prompt(tier="B") reproduces the recorded user_prompt exactly, sha256 98a9fb915dd6d6a19fa17eb048625eb58a8a1757a2c044a990d83e9f434fa830. TriageSlotDivergenceTest pins the still-open gap instead of asserting it away. The gate's TRIAGE_CASES are hand-written prose and are not in the format _evidence() emits: no truncation disclosure, no ordering claim, imports in a human's order. Closing that is not a formatting fix -- it re-scores the approved cohort, which is #2641's job and needs the GPU. So the tests name the distance in both directions and fail if it widens; test_the_two_scorers_do_not_agree_today fails loudly if the gap ever closes and this file owes an update. No production code changed. No model, no Ghidra, no service, no network. Verified: test_ghidra_fidelity.py 18 passed. 12/12 mutations caught across load_tier_b_evidence, build_prompt, assert_injection_present, _evidence and the gate -- including three that survived an earlier version of this file and whose absence is the point: dropping the numeric sort key, silently .get()-ing `pseudocode`, and emptying assert_injection_present's haystack. Those three now have their own assertions, and the address-order docstring no longer claims the shuffle test covers the numeric sort when it does not. benchmark suite: 16 files OK, 0 failed.
