PA.f77: table_view_prints_only_a_subjects_own_granted_affordances found the
holder's row with an unscoped view.find("{label} [{id}]"), which can match
the same marker in the Places occupant list first and then read whichever
subject row sorts first out of that mismatch — flaky about 1 run in 4.
Route it through the existing subject_row helper, which searches only from
the Subjects section onward. Swept the rest of the test module for other
unscoped find/contains that could cross into the Places occupant list or a
fact's known-by list; every other one was already either an intentional
"appears anywhere" check or already scoped through subject_row/
view_section. Stability: 8 sequential runs of the table:: suite, 41/41
passing every time.
PA.f79: two of the table's own refusal tests could pass under a mutated
implementation.
describe_refusal_names_unresolved_drafts_handle_and_expected_kind used a
handle literally named "missing_place", so a mutation that replaced the
rendered expected-kind with a fixed "thing" still passed the "place"
containment check via the handle text alone. Renamed the handle to
"unresolved_target" and pinned the exact rendered sentence.
describe_refusal_names_both_calls_for_a_duplicate_handle only ever gave
describe_duplicate_handle_sites two declarations to filter, both
colliding, so a filter that matched every declaration in the batch
regardless of handle produced the same "call #0 and call #1" text. Added a
third, unrelated declaration and asserted it is not named.
PA.f81: nothing pinned describe_refusal_to_actor's exact wording — every
existing test used `contains`, so appending a `{:?}` dump of the failed
precondition (leaking internal Mismatch shape the actor's own call never
handed back) would have survived all of them. Added assert_eq! tests for
one role-bearing precondition failure (CanBroadcast/NoAudience, a `horn`
channel role) and one roleless one (HasStanding/NoStanding), pinning the
full string each renders.
Every fix above was run against its own revert/loosening mutation and
confirmed to fail before being restored: the raw is_alphanumeric-neighbour
scoping wasn't touched here (that's PA.f78, committed separately), the
fixed-"thing" mutation, the match-every-declaration filter, and the
{:?}-append mutation on both PA.f81 branches all failed as required.
Lib suite: 620 passed, 0 failed, 1 ignored (618 baseline + 2 new PA.f81
tests; the PA.f77 flake no longer reproduces).
