Step 6 of milestone 410 "One owner per piece of guidance". CI now keeps the
shape decision #4027 set, so the next feature cannot quietly add a copy.
tests/test_guidance_ownership.py, 33 topics, each with an owner, markers, a
statement distinctive to the owner's full wording, and optional index markers:
- test_every_topic_is_stated_by_its_owner: markers and statement on the owner
- test_no_topic_is_stated_in_full_off_its_owner: the statement appears on no
other session surface (index, adapter static text and commands, live
context, other skills). Tool docstrings are not scanned; a contract may
elaborate the reflex that calls it.
- test_the_index_names_each_reflex_it_points_at: _INSTRUCTIONS keeps a
one-line pointer for each session-start reflex
- shared_with declares the one deliberate sharing: the note-check question
lives in create_note and in using-scribe for two different moments,
already pinned by test_verification_guidance_survives
- test_the_ownership_guards_can_fail shows each guard turning red (rule 167)
- the process topic now keys on get_process's "follow the returned body";
it had been passing on an unrelated "verbatim" in two other tools
tests/test_instruction_surfaces_agree.py keeps only what ownership cannot
enforce: the fold budget, rules-bind-names-preferences, and using-scribe's
pointer to reporting-back. Retired: the every-session-start-surface ask and
absence tests, the Systems and snippet owner pins (now registry topics), and
the SessionStart-without-ask test (#2497's shape). The push has carried no
rules since milestone 394, and requiring the ask beside every mention of it
would force a copy. The module docstring records where each protection went.
