From 08b3b77d69c4c16b1366dfa8e4b4b63165d34971 Mon Sep 17 00:00:00 2001 From: Glenn Gore Date: Wed, 11 Nov 2026 10:09:22 +1000 Subject: [PATCH 1/2] test(pnm): test the config-dir override without a process-wide env var `the_config_dir_can_be_overridden` set PNM_CONFIG_DIR with a comment claiming the test was single-threaded. It is not: libtest runs tests in parallel, and the override intermittently leaked into `the_default_dir_follows_pnm_rather_than_assuming_xdg`, which then saw /tmp/elsewhere. Split the override into `PnmConfig::dir_from` and test that instead; nothing in the suite sets an environment variable now.

Steps cover multiple writers, saves with basis/confidence/evidence and expiry/review dates, status changes, forget, and raw tamper/plant/copy; probes carry hard checks (top, absent, expectEmpty, refused, stale, describe, fence) that fail the run, or are `soft` — scored and listed as known gaps without failing it. Shaped after LongMemEval where it applies (knowledge updates, abstention, temporal validity). The fake keyspace moves to tests/common so the roundtrip tests and the harness share it. CI runs the evaluation as part of `cargo test` (a failed hard check fails the build) and again with EVAL_SUMMARY=1 to put the report in the job summary. The harness was mutation-checked: weighting inferences like statements, or letting retracted / expired memories through recall, each fails a hard check. Doing that found that only an empty-query probe catches the latter, since a zero status weight already hides them from a query. Its first run also found two ranking defects, recorded as soft probes: query terms match as substrings ("run" in "runner"), and there is no stopword list ("what is the for" matches three memories).
