The player had stats but no identity. `stat_schema.player` carried hp and
mana beside `npc.gwen.trust`, but where an NPC has a name and a
description the player had neither, so the block rendered as
`You: hp 100/100` and nothing in the prompt said who "you" was.
Three columns on `adventures`: name, pronouns, description. All
user-only, all optional, and an empty name means the app behaves exactly
as it did before — no backfill, no special case for an adventure that
predates the migration.
They are adventure columns rather than part of `stat_schema` for two
reasons. An adventure with no RPG layer still has a protagonist, and
that is the case this was added for. And `worldstate.schema._initials`
treats every dict inside a stat section as a stat definition, so a
persona placed there would be instantiated, rendered in the guide, and
handed an `initial` value as though it were one.
The paths do not change. `player.hp` stays `player.hp`; only the label
moves, to `Kaelen (player): hp 100/100`, the same way NPC lines already
print a display name beside the id. A path carrying the persona's name
would break the moment a player renamed their character, because
`_history_text` replays every past turn's stored delta into the prompt
and those blobs hold literal `player.hp` strings.
The section sits in the system block. Only the user can edit it, so it
never changes mid-story and stays inside the cached prefix. That is what
makes it free, and it is why the AI must not be able to move it — a
delta aimed at `persona.*` is already refused by `_resolve`, and there
is now a test holding that in place.
The modal that used to appear only for scenarios with `${Placeholder}`
tokens now always opens, and is where the character is named. Persona
and placeholders stay independent: a scenario asking for `${Name}` is
asking its own question. No scenario in the repo uses placeholders at
all, so the overlap is hypothetical.
Phase 2, which feeds the persona and the cast to the summarizer, is
written up in plan/18 and not started. That is where the memory-quality
problem actually gets fixed; this change is what gives it a name to use.
Not yet driven in a browser — plan/18 lists what to check by hand.

Migrations 66 to 73 drop `actions.index`, `variants`, `variant_index`,
`variant_count`, `state_before`, and `world_state_before`, plus
`adventures.memory_cursor` and `summary_cursor`. `index` is a keyword in
SQLite, so migration 71 quotes it.
Nothing outside the migrations read these. `models.py`, `schemas.py`, and
`ACTION_LIST_COLUMNS` lose the same eight fields, `Adventure.actions` orders
by `id`, and `attempts.renumber`, `context.history.max_action_index`, and
`nodes.next_index` are deleted.
Two changes keep the migration replayable on a `create_all` database:
- `_split_variants_into_siblings` wrote through the live ORM table, so it
stopped compiling once migration 66 removed five of its columns. It now
writes through `_ACTIONS_AT_60`, a frozen `Table` with its own `MetaData`.
- Five data passes read columns these migrations drop. Each now calls
`_has_columns` and returns early when the columns are absent.
`bootstrap` takes a `through` version so a migration test can stop at the
schema it asserts on.
555 tests pass, up from 549. Eight of the new cases assert each column is
gone after a real schema-45 database migrates all the way.

Every test module carried the same eight-line prologue redirecting the
database to a temp file. Only the first one to be imported ever took
effect: `app.database` reads `AIDND_DB_PATH` at import and builds `engine`
from it once, so by the time the second module ran the engine already
existed. The other 34 copies created a temp file that nothing opened and
nothing deleted, and leaked one per module per run.
`conftest.py` now does it once, which is early enough because pytest
imports conftest before any test module. It also deletes the file when the
run ends. The tests still share one database, exactly as they already did:
each `client` fixture calls `create_all` on setup and `drop_all` on
teardown, so no test sees another test's rows.
`tests/fakes.py` holds the one `ScriptedProvider`. Nine modules each had a
copy, and the copies had drifted into four feature sets, so a test that
needed to raise a provider error had to be written in one of the files
whose copy supported that. The shared one is the superset. The two
`FakeProvider` copies were the same class with a fixed reply, so they use
it too. `test_chat.py` keeps its own, which implements `chat` rather than
`generate` and records what it was constructed with.
An autouse fixture resets the fake's class state between tests, so a stale
reply list can no longer reach the next test.
435 lines out of the suite. 549 tests pass. Verified live by sabotage:
breaking the shared fake fails 13 tests across four modules.

* Rewrite comments in Google developer documentation style
Rewrite the comments and docstrings across the backend core modules so they
read plainly. The previous prose was accurate but dense and figurative, which
made it slow to skim.
Applies the Google developer documentation style guide: short sentences, active
voice, present tense, American spelling, and no metaphors, idioms, or
rhetorical asides. Replaces em-dash chains with separate sentences.
Prompt caching bills on a shared prefix: the endpoint reuses the request up
to the first byte that differs from last time and no further. The live
world-state block sat third from the top of the system message, so every turn
re-priced the instructions, the plot essentials and the whole story history
underneath it. The retrieved memories and the rewritten summary did it again.
Everything fixed is emitted first now, and everything that moves goes after
the history, ordered least-volatile first — which is also where recency serves
it best, the reasoning that already put the emit reminder last. The three tail
sections that are last for their own reasons stay last. The moved sections are
still charged to the token budget; only their position changed.
Two smaller halves of the same problem. OpenRouter serves a model from
whichever upstream is free and each upstream holds its own cache, so a
deepseek model now names deepseek as its preferred upstream — a preference,
not a restriction, so a turn still runs if that upstream is down. And the
endpoint's usage block is read back off the response and kept per attempt, so
the hit rate shows up in Insights and the debug log instead of being assumed.
