Build a fixture that can witness what a tree changes

Browse Source 
The stress fixture is sized from production and exists to weigh bytes, so it
leaves every column it does not weigh at its default. Checked against a freshly
built one, that is exactly the set phase 14 has to migrate: state_before and
world_state_before NULL on all 600 rows, no scenario and so no RPG layer, no
adventure scripts, both cursors 0, and a hundred retry histories whose two
attempts carry byte-identical text with variant_index pinned at 0.

That last one matters most. "Which attempt is live?" is the question SP4's
migration answers when it decides which sibling node becomes the head of a
turn, and against that fixture the question had no observable answer -- a
migration that picked wrong would have looked correct.

--rich fills in those columns and no others. A real RPG scenario read from the
seed data rather than invented, with a world state played forward so hp
declines and flags flip; monotonic per-action state snapshots, so a rollback
that does not happen reads as a wrong number instead of as nothing; a gold
script, story cards, non-zero cursors, pinned and forgotten memories; retry
attempts with distinct texts, counts of two and three, and a live attempt that
is often not the last written. Plus a second adventure, because a branch clause
that forgot its adventure still looks right on a database holding one.

The invariant SP4 reads -- text mirrors variants[variant_index] -- is asserted
at build time rather than assumed.

The plain fixture is untouched and re-measured unchanged at 1.8 kB, so the
egress ceilings stay comparable. All six shapes run clean on --rich, including
the turn path with the RPG layer and script pipeline now live. 283 tests pass.

Everything in it is synthetic and no real adventure is read. `*.db` is gitignored, so
the fixture never lands in a commit.
**A fixture to check correctness against, rather than bytes.** The measuring fixture
leaves every column it does not weigh at its default, which turns out to be exactly the
set a story tree has to migrate — `state_before`/`world_state_before` NULL on all 600
rows, no RPG scenario, no adventure scripts, both cursors 0, and retry attempts whose
text is byte-identical with `variant_index` always 0. `--rich` fills in those and only
those:
```
cd backend
.venv/Scripts/python.exe -m tools.stress_session --rich --actions 30 --memories 12
```
Prefer it small — it exists for variety per row, not for rows. **Its byte figures are
not comparable to a plain run**, and it does not replace the scale fixture, which still
holds the egress ceilings.
On Windows the report's box-drawing characters crash the default cp1252 console;
prefix with `PYTHONIOENCODING=utf-8`.
