gate: instructions_gate check 6 — the auto-memory index (R-229)
MEMORY.md is the larger half of what loads before a word is typed (8.4k tokens vs the root
CLAUDE.md's 6.6k) and is the one instruction file nobody hand-edits, so nothing was watching it.

Three deliberately different outcomes, each pinned by a test: over-ceiling FAILS (auto-memory
drops content past the limit with no error), an orphan WARNS (the store is outside git), and an
absent store PASSES while PRINTING its reason -- asserted on the reason text, because a pass with
no reason is indistinguishable from a gate that stopped running.

39 assertions (was 20). Red-proof run against the real store, not a fixture.

"""Fixture tests for instructions_gate.py.
Run: python3 scripts/test_instructions_gate.py
Every test asserts the EFFECT — the gate's exit code AND that its message names the file and the
reason — not merely that "it ran". A gate that exits non-zero for the wrong reason is not a gate.
The negatives matter as much as the positives here: the whole point of the HTML-comment convention
is that commented content costs nothing, so `test_comments_do_not_count_toward_ceiling` and
`test_version_literal_in_comment_is_allowed` are what stop the gate from punishing the very move it
is meant to encourage.
