JesseMarkowitzandClaude Opus 5 44edece67e M9: a campaign you can actually get back
A campaign could already be exported and imported. What could not survive the
trip was everything that explains it: the state events behind the authoritative
document, the prompt each turn was actually given, the passages it was shown,
the summaries that carry long-story continuity, and which take belonged to which
turn. An imported campaign could be read and could no longer say why it was what
it was — and a manual correction, the one state change no narration explains,
was indistinguishable from something the story had established.

The bundle is now `ai-dnd-adventure-v3`, and the version is the design rather
than a side effect. Everything added here could have been another optional key,
the way persona, Save Points, narrative state and imported knowledge each were.
That mechanism stops working at exactly this addition: a v2 file with no prompt
provenance is ambiguous between "written before M9" and "written by M9 from a
campaign that has none", and those are different facts about a campaign. A
version number is how a recovery file states what it was capable of recording.
v1 and v2 still import, and every seam from pre-active-head onward is tested for
the rule that an older file is never reinterpreted under a newer assumption.

Two categories became three. "Chosen travels, derived is recomputed" was enough
until stored prompts had to be decided: they are derived, and they must travel
anyway. The test that separates evidence from cache is not "could this be
recomputed" but "would a recomputation answer the same question" — a rebuilt
search index answers the same question, a rebuilt prompt says what the turn
would be told *now*, which is the opposite of what the inspector is for.

Also here: a real SQLite backup, through the online backup API rather than a
file copy, taken while the application is running and verified before it is
kept; story cards settled as compatibility-only legacy data and taken out of the
narrator's prompt, because they were the untracked path around knowledge
authority that IMPORTED-KNOWLEDGE-DESIGN §73 already forbade; and no schema
change at all, proved against a database M8's own code wrote.

Three defects, found by running the milestone's own tests rather than by reading
them. Deleting a campaign leaked its FTS index rows, and SQLite then handed the
freed ids to the next source imported into any campaign, which failed with an
integrity error that Reindex could not repair — both ends are closed, and a
database already carrying the damage now repairs itself. An imported node with
no state snapshot was being stamped with the campaign's head state, so an Undo
to turn 2 showed what the story knew at turn 20. And the snapshot relink did not
persist at all, because it mutated a dict in place on a column SQLAlchemy tracks
by assignment: it looked correct in memory and wrote the wrong ids to disk.

Carrying per-turn prompts looked like it would halve the length of campaign that
can be restored. Measured — and after compressing them inside the file —
everything M9 added costs 12% of it: the import ceiling moves from about 318
turns to about 279, against a 100-turn certification target. The dominant cost
is not M9's at all. The per-position narrative state document is 74% of a
bundle, and v2 already carried it.

Backend 1,102 passed / 14 skipped / 0 failed. Frontend 145 passed. Lint,
production build and Docker build clean. Verified across two server processes
with two data directories, and in a real browser against a real narrator.

"""M7: the imported knowledge library, against its acceptance contract.
The criteria this file carries are G01-G10, C05, F05's and F06's imported
halves, I05, H06-H09, and the additional cases `BUILD-MILESTONES.md` M7 names:
campaign
isolation, lexical retrieval without embeddings, a bounded knowledge budget,
deletion that preserves historical prompt evidence, hidden Canon that does not
leak into player knowledge, stale imported Canon losing to current state, and an
abandoned line of story failing to influence the retrieval query.
Three rules the assertions here follow, all learned the hard way in earlier
milestones:
* **Assert on the assembled prompt, not on a narration.** A model that fails to
mention a leaked passage is not evidence the passage did not leak. Every
authority and leakage test below reads the context the real builder produced.
* **Go through the real chokepoints.** Retrieval runs through
`knowledge.retrieval.retrieve`, the lineage-capped `history.tail`, and the
same FTS5 query the product uses. A test that reimplemented any of them could
pass while the product leaked.
* **Positive controls.** Every negative assertion is paired with the positive
one that proves the mechanism was working — "not retrieved while disabled" is
worth nothing without "retrieved while enabled" beside it.
