queue: open Q89 -- the import-time-I/O detector installed in all three forge harnesses is a name list (open, json.load, pickle.load, csv.reader, urlopen, codecs.open) plus a builtins.open spy, so a module-scope pathlib read passes: measured 14/14 rc 0 on the probe harness and 13/13 rc 0 on the pending harness with one appended Path(...).read_text(), each printing 'no import-time I/O'; done means an audit-hook or resolving-AST detector with one non-vacuity mutant per spelling and a docstring naming the modelled set; Q86 stays closed because 802a1ae meets its written done-means, and the dump harness is assumed affected on byte-identical code, not measured

+## Q89 — the import-time-I/O detector in the three forge harnesses is a name list, so a `pathlib` read at module scope passes every check green *(forge lane; opened 2026-10-27 by the pipe, at `6e9aeee`)*
+
+`802a1ae` closed Q86 as written. What it installed in all three harnesses is a static name list plus a `builtins.open` spy: `_IO_CALLS = frozenset({"open", "json.load", "json.loads", "pickle.load", "pickle.loads", "csv.reader", "csv.DictReader", "urllib.request.urlopen", "codecs.open"})` at `verify_triage_probe_refactor.py:404`, `verify_triage_dump_refactor.py:418`, `verify_triage_dump_pending_refactor.py:380` — identical in all three. Measured at `6e9aeee` in a scratch clone, one statement appended at module scope to the refactored module:
+
+| harness | module | appended | result |
+|---|---|---|---|
+| probe | `_triage_probe_refactored.py` | `from pathlib import Path as _P` / `_evade = _P(<this file>).read_text()` | **14/14, rc 0**, `OK: no import-time I/O (0 module-scope io calls; 0 runtime open calls)` |
+| pending | `_triage_dump_pending_refactored.py` | same | **13/13, rc 0**, same OK line |
+
+The module reads a file while it is imported and both detectors read zero. The static walk misses it because `_call_name` returns `None` for a `Path(...).read_text()` call — its `func` is an `ast.Attribute` over an `ast.Call`, not a dotted `Name` chain — and the spy misses it because `pathlib` reads through `io.open`, not the `builtins.open` attribute the spy replaces. `os.open` and `io.open` evade in the same way; Q90 has that table for beam's copy of the guard.
+
+**Done means:** a detector that fails an import-time read whatever its spelling — an audit hook on the `open` audit event (fires for `open`, `io.open`, `os.open`, `pathlib`), or an AST that resolves `Path(...).read_text`/`.read_bytes`, `os.open` and `io.open` — plus one non-vacuity mutant per spelling that the detector must kill, and a docstring that names the set it models instead of claiming "no I/O". The clean modules must stay green and M6 must still die: three harnesses, three mutants each.
+
+**Not claimed:** that any live module of the six reads at import (none does; all three harnesses are green on the clean tree); that `802a1ae` was graded wrongly — it meets Q86's own done-means, which is why the residual is a new item and not a re-opening; that the `HOST_SEED_LITERAL` hits are defects (they are not); that the dump harness is affected — I applied the mutant to the probe and pending modules only, and assume the dump harness only because its `_IO_CALLS` and spy are byte-identical.
