opus audit — phase 3 prep v4 (read-only verification of v3 fixes) #

verdict: PASS — all 1 major + 3 minor fixes from opus_audit_phase3_prep_v3.md verified. no files edited besides this report.

1. `PRE_TOOL_HYPOTHESIS_CLAUSE_RE` (major) — PASS #

probed directly via apply_speech_act_surgery(text, has_following_tool_call=True). the hypothesis regex does not match any of these and the whole sentence strips to '':

Let me check whether this was the cause.
Let me look at the alias table.
Let me read what the config has to say.
Let me run the build as root.
Let me check the logs as well.
Let me verify the alias works.
extra: I'll check what the log has to say., Let me check if it was cached so that we know.

real hypotheses are kept (group 1 → output):

...because the cache may be stale. → the cache may be stale.
...since the port changed. → the port changed.
Let me test this hypothesis: the lock is never released. → the lock is never released.
...cache, then rebuild the index. → rebuild the index.
...logs, as the daemon crashed. / ..., since it was flaky. → kept clause

trailing path matches too: Patched it. Let me verify the alias works. → patched it.; Here is the fix. Let me check whether this was the cause. → here is the fix.. falsifier (a split in the middle of a word on was/alias/has/as root/as well): not triggered.

2. `CHOICE_FORK_QUESTION_RE` — PASS #

stripped (not a fork → solicitation removed): Want me to push it or not?, Shall I keep it or not?, Do you want me to apply it, or would you rather I wait?, Should I apply the patch or would you rather review first?
kept (real fork): Want me to write it in Rust or Go?, Do you want to keep or migrate?, Should I keep or migrate the old table?

3a. inline code emoji protection — PASS #

L369 splits on (`[^`\n]+`) and skips odd indices. Run `print('🚀')` to test 🚀 nice. → run `print('🚀')` to test nice. (1 stripped). Shipped 🚀 (◕‿◕✿) `a 🎉 b` and ```x='🔥'``` ok ✨ → kaomoji, inline 🎉, fenced 🔥 all preserved; 2 prose emoji stripped. inline code case is also kept as-is (not lowercased).

3b. `phase3_lora_and_transplant.py` L93 comment — PASS #

reads (96 trunk writers + 96 router gates = 192 tensors). matches the regex for 48 hybrid trunk layers: 1 residual writer (ssm_out xor attn_output/attn_out) + ffn_down_shexp = 96, and ffn_gate_inp + ffn_gate_inp_shexp = 96. blk.48 (MTP) is correctly excluded. (i didn't check this against a real GGUF tensor list; i only checked the regex arithmetic.)

4. self-tests with `python3 -B` — PASS #

script	exit	output
`scripts/prepare_phase3_sft_data.py --self-test`	0	`self-test: PASS`
`scripts/phase3_lora_and_transplant.py --self-test`	0	`self-test: PASS` (C Q2_0 golden compiled + ran)
`scripts/slice_qwen4exp_gguf.py --self-test`	0	`self-test: PASS`

glob("**/__pycache__") was empty before and after the runs (and after my own importlib probes with sys.dont_write_bytecode=True).

remaining issues #

none blocking. one nit: an opener whose only content is a hypothesis is reduced to that clause in lowercase without a subject (the cache may be stale.). that's intended per M2 and fine for SFT.
