JesseMarkowitzandClaude Opus 5 1ce9972760 M8: the browser becomes the storyteller
The interface was AI-DnD's with this product's features bolted into it. The
navigation read Home · Adventures · Scenarios · Settings · AI Chat; starting a
story meant first picking a *world*, and making a world meant a JSON stat-schema
form, a story-card table and an art picker. The play screen had a Branches tab.
The input had three modes. Sixteen of the sixteen controls on a two-turn story
had no accessible name — they were single glyphs with a tooltip.

All of that was measured in a real browser before anything was changed, and the
measurements are in planning/reports/M8-IMPLEMENTATION-REPORT.md §C. Almost
nothing underneath was wrong: the play loop, the history controls, the takes,
the Save Points, the state correction and the knowledge library all worked. What
was wrong was what a reader was asked to understand in order to use them.

So the shape now is one entry point and one screen:

  Campaigns -> Campaign -> Story
                           State · Knowledge · Context · Save Points · Settings

Everything that is not the story lives in a panel that starts closed. The
top navigation bar is hidden on the story screen entirely, because on that one
screen the story is the interface.

Play is one natural-language field. An action and a piece of quoted dialogue are
both just what the reader wrote, and B01/B02 confirmed against a real narrator
that the model reads the quotes without being told which kind of turn it is.
What survives from the old Story mode is a Story direction toggle, which is not
a fourth mode: it changes who is being spoken to, not what kind of action is
taken, and the box is visibly marked while it is on.

Branch, fork, node, merge and head appear nowhere a reader can see them. The
branch panel and the tree overlay are gone from the browser. The mechanism is
untouched — takes, divergence, retained futures and Save Points all still work,
and their endpoints are still tested. This is a decision about what a reader is
asked to understand, not a reduction of what the product can do.

The two defects worth the space:

A player action is stored with AI Dungeon's "> You " prefix. That was right when
the Do mode asked for a bare verb phrase. With one field the spec tells the
reader to write "I enter the tavern", and the result was "> You I enter the
tavern." — in the transcript, in the replayed history, and therefore in the
narration, where a small model imitates it and writes "You I thank her". M8's
own design surfaced it, so M8 fixed it: the prefix is added only when the reader
has not already written a subject. The ">" marker, which is what actually
identifies a player turn in the prompt, is unchanged in every case.

And a stale `.input-bar { display: flex }` in play.css overrode the new
composer, because that sheet is imported after the new one. The direction row
and the input row laid out side by side and the box was unusably narrow. Found
by opening the product in a browser, not by reading the CSS — which is the
argument for having done that first.

Failures now have the taxonomy the spec asked for rather than one toast: model,
generation, state, knowledge, server, each with the thing to do about it. A
failed turn leaves the reader's words in the box and says so. The classification
reads backend strings, so it is a fallback ladder rather than a lookup — an
unrecognised message still classifies, still shows the server's own words and
still offers Retry.

`Settings.model` could be empty with nothing saying so until the first turn
failed with a provider error. The header now reports Ollama in five states, and
an unconfigured or missing model offers the models actually installed on the
endpoint, from the connection test that already knew them. Nothing is chosen
automatically: an endpoint's first model may be an embedding model, which cannot
narrate at all.

Narrator prose is rendered as safe Markdown — headings, emphasis, lists,
blockquotes, code. The safety is structural rather than filtered: every node is
a React element built from parsed text, and there is no dangerouslySetInnerHTML
in the file. A sanitizer is not needed to make markup safe if markup is never
produced from input. Link schemes are checked with the URL parser rather than a
pattern, because the bypasses are all in the parsing. A remote image is a
placeholder naming the blocked address; the knowledge and context panels
deliberately do not use this renderer at all, because they exist to show a
reader exactly what is in their file.

Backend, and only what the browser could not otherwise reach:

  AdventureCreate.opening   a start action could only come from a Scenario, so
                            every campaign made in the new setup flow opened on
                            a blank page. Same node, same code path.
  canon_rules               campaign_canon has been the highest authority in a
                            campaign since M5, read by the prompt builder and
                            the state validator, and had no API at all — a
                            fixture had to write it with SQL.
  a 401 and a 429 message   the last user-facing text describing a hosted
                            deployment. One told the reader to check an API key
                            that has not existed since M2.

No schema change and no migration: proved by building a database with a server
running the M7 commit's own code and opening it with this one.

The project had no frontend tests. It has 132 now, across ten files, running
in about six seconds — the enabled state of every history control, the take
selector, the confirmations, the panels, the five model states, the failure
taxonomy, the focus trap, accessibility, and that the reserved dictation control
never touches the microphone. Writing them found a real defect: the focus trap
filtered candidates with offsetParent, which is null inside the fixed-position
ancestor the dialog has and which jsdom never computes — it would have behaved
differently in the tests from the browser.

They do not replace the real-browser runs, and both kinds of evidence are in the
report. The browser suites drive the production build served by the real backend
with a real local narrator, including a genuine process restart.

A verification pass over all of it then found three more, each by driving the
product rather than reading it:

Stepping between alternate takes did nothing. The pager asked whether a take
lived on another line by comparing `target.branch_id !== action.branch_id`, and
`ActionOut` has never carried `branch_id` — so the comparison was permanently
`number !== undefined`, always true, and every step took the branch-switch path.
For two takes of an ordinary retry, which share a line until one is written
below, that meant switching to the line already being read: the same window came
back and nothing moved. D07 is a required v1 acceptance test. The fix needed no
new field — the variants list already carries every attempt's branch and marks
the live one.

The first regression test for that passed against the broken code, because its
fixture gave the action a `branch_id` the real payload never sends. That is the
exact failure M7's review was about, so the fixture was corrected, the tests were
re-run against the reverted code and failed for the right reason, and the
fixture now carries a docstring saying why the field must never come back.

And the knowledge panel pointed readers at an "embedding model" while the
setting is called "Model for meaning-based search" — a reader sent looking for a
field that does not exist by that name.

Campaign canon was measured rather than assumed. Editing it after play is a
configuration change: every turn already played keeps the canon it was actually
given, in its own context snapshot, and the accepted story, the state document
and the state audit log are byte-identical across an edit. It is not routed
through M5's state audit, because canon is not narrative state and doing so
would create the second representation the spec forbids. What the editor does
now is say so, once a campaign has moments.

`BROWSER-UX-SPEC.md` §38 asked for a "Show Hidden Story State" toggle. There is
no hidden story state — a secret lives in a narrator-only knowledge source and
never enters the state document. The section is rewritten to require what it
actually meant: ordinary surfaces must not carry narrator-only information,
advanced inspection must withhold it by default behind an explicit warned
choice, and no second store may be invented to give a toggle something to
reveal. The protection is stricter than before, not weaker.

Closeout. An independent review returned M8 IMPLEMENTATION: PASS subject to
evidence and documentation cleanup, and this commit carries that cleanup:

The report named two frontend bundles as the artifact behind its acceptance
evidence. The saved run logs settle it. index-Ii-lARp9.js, built at 18:53:02
from this tree, is the one final frozen artifact behind all 157 browser checks;
index-C6E5Uvtu.js is superseded — it predates the D09 fix and its acceptance
suite ended 54/55 on exactly that defect. No tracked file under backend/app or
frontend/src has a modification time after the freeze, so the whole final
campaign describes one build. §P sets the two side by side.

Finding 14 — the app budgets 16,384 prompt tokens while an Ollama that sees no
VRAM enforces 4,096 — is resolved operationally, with no application change.
The OpenAI-compatible endpoint this app speaks accepts num_ctx and ignores it,
and reloads the model at its own default, so a native call cannot prime it
either. A model derived with POST /api/create carries the parameter, is honoured
through the app's own OpenAI-compatible path, and appears in /v1/models — which
is the listing the Settings model picker already reads. Measured end to end.
The procedure is in DEVELOPMENT.md; nothing in the repository depends on any
particular derived model existing. Adding provider code to work around this was
declined deliberately: it would mean either a second native request path,
against ADR 011, or a parameter the endpoint provably ignores.

The §38 rewrite is ratified as a requirement clarification aligned with the
implemented architecture, and the spec gains the clause finding 3 was really
about: withheld material must be absent from the rendered DOM, not merely
collapsed in it.

The report's §U carries the M9 handoff — what a portable campaign has to include,
whether historical context snapshots belong in the bundle, what happens to
inherited story cards, and that a restored campaign may meet a different context
window than the one that wrote it. None of it is implemented here.

Final: backend 950 passed / 14 skipped; frontend 132 passed; lint, production
build and Docker build clean; 157 browser checks across six suites, zero
failures. M8 is implemented, verified, reviewed and accepted (2026-09-06).
M9 has not been started.

JesseMarkowitzandClaude Opus 5 480414efe0 M7: a first-class imported knowledge library
A campaign can import local .txt and .md files as Canon, Reference or
Inspiration, and the class is load-bearing rather than a label: it decides the
words a passage is framed with in the prompt, the weight it carries when
passages are ranked, and which budget it competes in when the context is tight.

This is a separate subsystem, which is the Phase 0B decision
(IMPORTED-KNOWLEDGE-DESIGN.md §73). Story Cards do not carry classification,
provenance, content identity, chunking, an index or a lifecycle, and they were
not promoted into something that does. Nothing here reads or writes one.

The subsystem, in backend/app/knowledge/:

  classes      the three classes, their weights, and the prompt framing
  chunking     deterministic, heading-aware, 60-800 tokens, no overlap
  fts          SQLite FTS5 with porter stemming; scoped and bounded in SQL
  importer     validate, hash, store, chunk, index — in one transaction
  embeddings   local Ollama vectors through the shared provider
  retrieval    query construction, hybrid merge, rerank
  inject       the budgeted cut and the rendered prompt sections

Relevance admission is a separate stage from ranking, and that separation is
the milestone's most expensive lesson. An independent review found the first
implementation deciding relevance with a floor expressed as a share of the best
candidate — which the best clears by construction — so a passage was admitted on
every turn regardless of the scene. A query about tide tables and container
tonnage retrieved all five sources of a fantasy campaign, narrator-only hidden
Canon among them.

So the pipeline is now:

  candidate generation -> admission -> ranking -> class weighting -> budget

Admission reads raw, candidate-set-independent signals: the cosine the model
returned, and how many distinct meaningful query terms a passage contains.
Ranking reads normalized ones, because bm25 has no fixed range and cosine's zero
is not zero. Normalization decides order among things that matched; it can never
decide whether anything matched. Authority is applied after admission, so a
class orders what matched and never rescues what did not.

Retrieval may therefore return nothing, and on a scene unrelated to the library
it does.

The other decisions that each replaced an obvious wrong one:

- The class multiplies relevance rather than adding to it. An additive bonus
  satisfies "Canon outranks Reference" and makes "do not include irrelevant
  Canon" impossible, because a large enough constant wins on its own.
- The semantic floor is measured, not guessed: 113 production-path pairs against
  nomic-embed-text put targeted matches at 0.55-0.85 and off-topic pairs at
  0.36-0.56, and 0.58 sits between them. Because it is a property of that model
  and not of cosine similarity, it is keyed to the model rather than applied to
  whatever is configured: an embedding model with no measured calibration in
  this build does not borrow the number. Semantic admission is skipped, the
  campaign retrieves lexically, and the reason is stated in the knowledge status
  and in the turn's provenance. Degrading to lexical keeps the library usable;
  lending the threshold to an unmeasured model is how the admitted-everything
  defect would return.
- One lexical term is not evidence. Two distinct meaningful terms, or one that
  is neither a standing campaign entity nor a negligible share of the query.
  The stop list grew from 42 words to 261, all function words — no subject
  matter, because a stop list that removes subject matter stops finding "The
  Silver Key".
- Lexical retrieval is a production path, not a fallback. It finds the proper
  nouns and invented terms a setting bible is made of, and the library is fully
  usable with no embedding model configured.

Safety is structural rather than filtered. Imported text reaches the prompt
whole, inside a section that says what it is, under a rule stating the authority
order in words and refusing every instruction inside it. No endpoint accepts a
filesystem path, so H08 has no mechanism to escape from. Nothing renders
imported content as HTML, so a script tag is five visible characters and a
remote image is never fetched. Import, chunking, indexing, retrieval and a turn
open no socket at all; only embeddings do, through the endpoint allowlist the
memory bank already uses.

Provenance is the rendered text, not a foreign key: deleting a source cannot
turn a historical turn's evidence into dangling ids.

Schema: knowledge_sources, knowledge_chunks, knowledge_embeddings, and an FTS5
virtual table attached to knowledge_chunks as a DDL hook so it is created and
dropped with the table it indexes. Migration 92. A pre-M7 database opens
unchanged and needs no sources to play.

Bundle: the source content and the reader's judgements about it travel; the
passages, index rows and vectors are rebuilt on import, so a restored campaign
is searchable immediately without a reindex step.

One runtime dependency: python-multipart, Starlette's multipart parser. It is
what makes the upload surface possible, and the upload surface is why no
pathname is ever accepted.

The test doubles were the reason the defect shipped, so they were corrected too.
The retrieval stub scored unrelated text at 0.06-0.20 where the real model
scores it at 0.43-0.44, and its docstring said it had deliberately removed the
constant component that "would put a similarity floor under every pair" — which
is exactly the property real models have. The stub now has that floor, one test
fails if it is ever removed, and another reproduces the superseded rule and
asserts it is still fooled by the same fixture. Run against the pre-corrective
implementation, the new suite fails 13 of 18.

Tests: 939 passed, 14 skipped (836/7 at M6). 110 new across seven files, one of
which mocks nothing between itself and Ollama and re-measures the similarity
separation on every run. 43/43 checks in a real Firefox, reproduced.
Docker build clean.

Four other defects found by review or by the browser run were fixed here rather
than carried: an unreachable relevance constant that appeared to enforce
something and did not; acceptance tests using the wrong fixture files, so G07's
trap was never exercised; a bidirectional override surviving into displayed
filenames; and, from the implementation pass, the Insights panel showing M5's
two state sections as raw keys and the source inspector refetching on every
keystroke.

M7 was independently reviewed, which returned PASS WITH CORRECTIVE WORK
REQUIRED. Both blocking findings are closed, and closeout resolved the
embedding-model calibration boundary the corrective pass had left as debt.
planning/reports/M7-IMPLEMENTATION-REPORT.md carries the review, the corrective
closeout and the closeout verification in sequence, none overwriting another.

JesseMarkowitzandClaude Opus 5 a6e9c7a32b M6: branch-safe context, summaries and long-term story memory
Aligns the inherited AI-DnD memory and context foundation with the history,
authority and state model M3-M5 established. Long stories now reach the narrator
through a bounded, lineage-safe, inspectable context rather than a growing
transcript.

This commit includes the corrective work that followed the independent review in
planning/reports/M6-IMPLEMENTATION-REPORT.md. The first implementation reported
E03 as passing and it was not; the report records that history rather than
hiding it.

What was already correct, and was kept rather than rebuilt

  Memory lineage. Memories already carried (branch_id, depth) and retrieval
  already filtered through the capped-path clause; the ten-step negative control
  was measured passing against b7005e6 before any change here. M6 adds the
  regression tests that pin it, plus provenance and authority on the result.

Summary lineage — both halves

  A summary is a row carrying the coordinate of the last node it covers, and
  eligibility is the same head-capped lineage clause memories use. That alone
  was not enough: generation was seeded from adventures.story_summary, a
  campaign-global column with no lineage, so after a divergence the summariser
  was handed the abandoned line's prose and asked to update it. The row it
  produced was correctly anchored and therefore looked safe while its sentences
  described a story the reader had left.

  Generation is now seeded from summaries.current — the same question the
  context builder asks — so the input and the output are scoped by one rule.
  adventures.story_summary remains a reader-facing mirror for the Plot panel and
  the export bundle, kept in step when a summary is written and when the head
  moves, and nothing authoritative reads it.

Retrieval redundancy

  With a real embedding model, four near-identical memories crowded out the one
  distinctive clue, which survived only because the default memory_top_k is 5.
  Retrieval now drops a candidate that repeats one already chosen, never across
  authority classes, at a threshold measured against the configured embedding
  model. The clue is retrieved at top_k 5, 4 and 3. Ranking itself is unchanged;
  the further factors CONTEXT-AND-MEMORY §20 contemplates remain unimplemented
  and are recorded as such.

Memory authority, budgeting, observability

  Memory.authority is accepted_story or heuristic, classified by the application
  and marked in the prompt; retrieval never writes state. The reply is reserved
  out of the context budget, and an impossible configuration fails clearly
  instead of overflowing. Each derived pass records ok/idle/failed per campaign,
  served by GET /adventures/{id}/derived and shown in Insights, so the M2
  failure — a dead memory bank with a green suite — is visible if it recurs.
  Provider-wiring tests mock no factory.

Also: two pre-existing test-suite leaks fixed; two fixtures that stored one
vector in every memory now use distinct ones, so lineage assertions stay
readable alongside redundancy suppression.

Planning: CONTEXT-AND-MEMORY, TECHNICAL-DESIGN, DATA-MODEL, V1-ACCEPTANCE-TESTS,
BUILD-MILESTONES, VERSION and planning/README updated to describe what exists,
including that a valid E03 test must regenerate a summary after diverging. The
M5 report was rotated to planning/archive/milestone-reports/. No new ADR — every
choice implements a decision the package had already settled.

JesseMarkowitzandClaude Opus 5 b7005e6fdd M5: genre-neutral authoritative narrative state, with review corrections
Replaces AI-DnD's RPG relative-delta world state with the genre-neutral typed
narrative state of ADR 010: explicit, absolute, allowlisted events proposed by
the model, validated by the application, applied to one authoritative document,
and snapshotted per position so restore stays a row read.

This commit includes the corrective pass that followed the independent review
in planning/reports/M5-IMPLEMENTATION-REPORT.md. The invariant it exists to
hold is:

    visible active transcript position == stored head == authoritative state

Narrator editing (D10, STORY-BRANCH-SEMANTICS §§14-15)

  A narrator edit no longer rewrites a row. It returns to the state before the
  turn, takes the reader's exact text as the accepted narration, re-derives the
  state that text implies, and becomes a new active continuation — while the
  original narration keeps its words, its live flag and its whole future as
  retained history. At the tip the correction is another take; with story below
  it, it forks. No new history machinery: this is the existing fork/take/head
  path with the reader's text in place of a generated reply. The §14A refusal
  is therefore gone for narrator turns, and remains only for player input.

Pre-M5 positions

  Migration 88 backfills the empty narrative document onto every action written
  before M5, and a missing snapshot now restores the empty document instead of
  leaving the previous position's state standing. Restoring to an old Save
  Point no longer leaves a later position's entities and facts on screen.

Narrator context

  Replayed history carries prose only; the machine-readable block is no longer
  reconstructed into past turns, where it contradicted the authoritative state
  in the same prompt. A fact withdrawn by a manual correction is now named as
  no longer true, with the reader's reason, rather than silently dropped.

Also

  - state_changes joins the action-list bulk read, removing one query per row.
  - Extraction takes only the application's own protocol payload: an ordinary
    ```json or ```python block in a story survives, and a mangled proposal
    still does not reach the reader.

Planning: ADR 013 records the authoritative document shape; §§14-15/14A, D10,
C04 and BUILD-MILESTONES are updated to describe what exists. Debt is recorded
against M8 (scenario editor UX) and M9 (export of the audit trail).

JesseMarkowitzandClaude Opus 5 62a997f364 M4: close out Save Points, with browser verification
Closes M4. The review's three findings are fixed, the durability rule the
specification always implied is now enforced, and M3's and M4's browser
behaviour has been verified in a real browser for the first time.

B-1 -- the Save Point list was an N+1 that loaded whole Action rows,
narration included, to answer "does a row exist here". It is now one bulk
two-column coordinate query plus one lineage: 53 SELECTs for 25 Save Points
became 5, and the count no longer grows with the list. The clause is an OR
of exact (branch, depth) pairs rather than two IN lists, because the cross
product would report a Save Point resolved on the strength of another one's
depth existing on this one's branch. A test builds exactly that trap.

B-2 -- reclassified during closeout from "missing warning" to a behaviour
defect, and fixed as one. STORY-BRANCH-SEMANTICS §19 says a named checkpoint
remains until explicitly deleted, and §28 already required future cleanup to
retain checkpoint-referenced paths; a cascade that silently removed Save
Points with a branch violated both, and a warning would only have documented
the violation. A branch a Save Point names can no longer be deleted. The
request is refused with the offending Save Points named, the user deletes
them explicitly -- which deletes no story -- and the branch then goes. The
scope is the subtree, because deleting a branch takes its descendants. Both
delete controls disable and explain. Recorded as a new §19.1; models.py,
TECHNICAL-DESIGN §8.8 and DATA-MODEL §8 had all recorded the cascade as the
rule and now record the refusal.

An earlier pass in this same closeout had kept the cascade and added a
warning. That was the wrong fix and its tests were replaced rather than left
standing, since they pinned the defect.

B-3 -- the D11/L03 automation never left one process, so it could not
distinguish durable state from a live Python object. It now spawns real
server processes, kills the first, and reads the campaign back with the
second.

C-5 -- creating a Save Point takes the campaign's turn lock. "Save where I
am" has to name one committed position, and the head is what a turn in
flight is about to move. Rename and Delete deliberately do not take it.

The architecture is untouched: a Save Point is still name + note +
(branch, depth), and restore is still coordinate -> head.move_to_node ->
head.move_to -> attempts.restore_state. No second restore path, no state
copied into a checkpoint, no fork on restore.

Browser verification -- the first in this project, and it covers both
milestones. Firefox 154.0.1 through geckodriver over the W3C WebDriver
protocol, driving the rendered DOM: 47/47 checks, twice, on independent
databases, no console errors. M3's Undo/Redo enable states, transcript
movement, Retry and the take pager, divergence retiring Redo; M4's whole
Save Point lifecycle, both confirmations, and the new branch-delete refusal
including its recovery. No dependency was added: the WebDriver client is
stdlib HTTP.

No application defect was found by the browser. Four failures occurred, all
in the harness -- a wrong SPA route, a wait comparing transcript length when
the empty-story placeholder is longer than the first turn, a fixture
deleting the branch it was reading, and a reload assertion that sampled
once instead of waiting. The last was checked against the app before being
called a harness bug.

Tests: 698 backend pass (was 680), 60 M4, 94 M3 history, 66 export/
migrations, 93 security/local-only. Frontend lint and build clean, Docker
build clean, loopback binding unchanged. No assertion weakened, no skip
added.

Planning: STORY-BRANCH-SEMANTICS §19.1 is the only behavioural change and it
strengthens §19. V1-ACCEPTANCE-TESTS records D11-D14, I04, L03 and the
E-series, keeping automated, live-runtime and browser evidence distinct, and
weakens no pass condition. DATA-MODEL records the coordinate with the retry
measurement that settles it. BROWSER-UX-SPEC rules for Moment over Turn.
BUILD-MILESTONES marks M4 COMPLETE, closes M3's browser condition, and lists
what M5 inherits. VERSION adds v2.6.

No new ADR: ADR 005 already decides that history is preserved rather than
overwritten, and §19.1 is that decision applied to checkpoint-referenced
history.

M4 is closed. M5 may now be briefed; it has not been started.

JesseMarkowitzandClaude Opus 5 e08d49c3eb M4: add durable named Save Points
A Save Point is a name for a story position, and restoring one is head
movement. That is the whole architecture, and it is what ADR 012 and
BUILD-MILESTONES' note on M4 asked for: M3 made the head a stored
(branch, depth) and made arriving at one a row lookup plus a state restore,
so a Save Point needs no restore machinery of its own.

What the user gets:

- Name the moment they are reading, keep playing, restart the app, and come
  back to it. Restoring moves the story back and deletes nothing: the later
  turns stay, Redo still walks forward into them, and writing something
  different is what starts a new line while the old one is kept.
- Rename, delete, and a list, in a Save Points panel beside the branch panel,
  with a Save Point button next to Undo and Redo. Both confirmations say what
  is *not* destroyed, because that is the part the screen cannot show.
- Save Points survive export and import.

What was deliberately not built:

- No second restore path. `head.move_to_node` is the only new movement: its
  depth half is M3's `head.move_to` unchanged, and its branch half is the
  single assignment `switch_branch` already makes. No head field is written
  in the checkpoint router, nothing reconstructs state, nothing prunes a
  memory, nothing copies or deletes a turn, and restore never forks — the
  first write below the restored head does, through `fork_if_behind_head`.
- No automatic cleanup. A Save Point behind the head, or naming a line the
  story left, is doing its job (STORY-BRANCH-SEMANTICS §19). The one removal
  is a cascade: deleting a branch takes its Save Points, as it takes its
  memories, because the story they named went with it.
- No new ADR. ADR 012 already decides the architecture, and a table is not a
  decision.

The one call the planning package did not already make: restore moves the
branch half of the head only when the coordinate is off the path being read.
Doing it unconditionally would quietly hand back an abandoned continuation
whenever a Save Point in a shared prefix was restored; never doing it would
make a Save Point on a departed line unrestorable, which contradicts §19.
TECHNICAL-DESIGN §8.8 records it.

Schema: a `checkpoints` table holding a name, an optional note and a
(branch, depth) coordinate — no copy of any story. `create_all` builds it as
it did `memories` and `branches`; migration 80 adds the index. No backfill,
because nobody had named a position before M4.

The coordinate is deliberately not an action id: one coordinate holds every
attempt at a turn and exactly one is live, so a coordinate follows a retry
where a row id would pin a take the story no longer tells.

Tests: 680 pass (638 before). 42 new in tests/test_save_points.py covering
D11-D14, I04, L03, E-series lineage and memory isolation after restore and
divergence, the edge cases, and an M3-database migration. One pre-existing
fixture in test_tree_migration.py needed `checkpoints` added to its drop
list — SQLite refuses to drop a table another table references.

Not verified: the browser. No session has had a usable one, so the Save
Point panel's DOM behaviour is unobserved — as M3's Redo control still is.
The twenty-step sequence was driven over HTTP against a live server with a
real process restart instead, and all seventeen checks pass. M4 is
implemented, not accepted: no review has been written.

JesseMarkowitzandClaude Opus 5 7f082b61d8 M3: complete non-destructive history and active-head export
The head-cursor model landed in 903fa7a and stopped there: the backend
moved the head instead of deleting turns, but a bundle still reopened at
its newest row, the browser had no way forward, and five inherited tests
still asserted the contract Undo had just stopped honouring. This is the
rest of the milestone, plus the one unsafe operation the review found.

Export now writes headDepth, and it belongs on the other side of the rule
app/bundle.py states about itself. The head depth used to be derived —
the tip of the head branch, a fact about the nodes that arrived with it —
and that was true while Undo deleted, because the newest row was the only
place a story could be read. It is a decision now: the same tree exports
identically whether the user undid three turns or none, so the file has
to say. An import that ignored it would silently Redo the story to its
newest retained turn, which is the Phase 0B export finding this milestone
exists to close. A file with no headDepth is opened at the tip, which is
not a fallback but the position such a file recorded; a file naming a
depth its own rows do not reach is refused in plan(), before a row is
written, for the reason that module gives about half-written trees.

Which branches the story has left goes into the file for the same reason.
Every row of an abandoned line arrives on an import either way, so the
disposition is the only thing telling it apart from an active one, and a
restored backup that had lost it would have nothing for the later cleanup
and recovery screens to select on. Both keys or neither: a time with no
depth cannot say what was displaced.

The browser gets a Redo button beside Undo, on Ctrl+Shift+Z, and both are
enabled from can_undo/can_redo rather than from the transcript. Neither
is derivable on the client — Undo stops at the campaign opening, which
may be off the top of the loaded window, and Redo depends on the retained
future, which the client is never sent — so the flags now ride on every
window the server hands back, including a scrolled-up page and the
response to an import. Moving the head also refreshes the state panels,
which undo never did: it has rolled the world state back since long
before M3 and the drawer kept showing the old numbers.

An in-place edit is now refused when story descends from the turn and is
not on screen. Editing rewrites one row and re-evaluates nothing, which
is what makes it a correction rather than a continuation, and that is
harmless while everything below the turn is visible — the reader can see
what their change has to agree with. It stops being harmless when the
continuation is undone, or was left behind by a divergence, because the
edit then silently changes the words an invisible stretch of story was
written from. That was the one way M3's retained history could be made to
contradict itself. Refusing is deliberately the whole of the fix: making
such an edit fork is STORY-BRANCH-SEMANTICS.md §14-15, and §15 wants the
state the edited prose implies re-evaluated, which is M5's extraction
pass. The requirement is not weakened, only deferred, and §14A now says
so.

The predicate asks one question rather than two. A descendant is
invisible either because it is past the head on this lineage or because
it is past a fork on a branch the story left, and both are "a live node,
deeper than this one, descending from it, off the path being read". A
first attempt scoped the search to branches other than the active one and
failed the divergence case, correctly: the departed branch is usually an
ancestor of the branch now being read. Only the deepest live node on each
descending branch is examined, because visibility is monotone in depth.

Five inherited tests are rewritten rather than deleted, because what they
were protecting is still worth protecting and only the mechanism changed.
The undo-state pair keeps its state assertions and swaps "the rows are
gone" for "the rows are all here and the story is read from earlier". The
memory test stops asserting that undo prunes memories and starts
asserting the property that replaced it: a memory past the head is
unreachable, still on disk, and retrievable again after Redo, with no
re-embedding. The attempt-group test still proves the group moves as one,
out of the story rather than out of the database. And the fork test
reverses: Undo used to refuse at a fork point because it deleted rows the
parent branch was also reading, and with nothing deleted there is nothing
to protect the parent from, so it now walks into the story the branch
inherits and stops at the campaign opening instead.

tests/test_head_cursor.py is the milestone's acceptance contract, named
by the items it discharges: D01-D10, E01-E04, I01-I03, I07, L01-L02, and
the invariant they all rest on — Undo deletes zero accepted turns,
asserted on row ids over the whole retained tree. E02 has both controls,
because a negative control alone would pass if memory retrieval were
simply broken. L01 records what it does not claim: the head does move by
one on a failed turn, onto the player's retained input, which is A05
rather than a gap. Two of the edit-guard tests exist to prove the guard
stays out of the way — a correction at the tip and a correction mid-story
with everything visible must both still work.

638 backend tests pass. Frontend lint is unchanged at seven pre-existing
warnings, none in the files touched; the bundle builds at 395.85 kB; the
production image builds.

Verified at runtime against the trusted-LAN Ollama over HTTPS: three
turns, two Undos, a Redo, a Retry, an Undo, a divergent continuation,
Redo correctly refused with 400, Undo back to the opening, export, a
process restart that reopened the campaign still undone, and an import
that opened at the same position with its retained future intact. The
browser click-through of that sequence has not been run — no session in
this milestone had a browser to drive — so the Redo control itself is
verified by its endpoint and its lint and build, not by a click.

JesseMarkowitzandClaude Opus 5 903fa7a74f M3: move the story's head instead of deleting its turns
Undo deleted. It removed the trailing AI action and the player action in
front of it, pruned the memories covering them, and let the tip fall back
to whatever survived. That made it the one operation in the application
that destroyed accepted story, and it was why there was no Redo: the
turns to move forward into no longer existed. Phase 0B demonstrated the
head-cursor alternative in a disposable spike; this is that concept as
production code.

backend/app/head.py is the whole of it. Three questions that used to be
one — where the story is being read, how far it is retained, and where it
opens — are now three functions, and every caller that moves the head or
asks about it goes through this module. The spike put the fork check in
the write path and left Retry and Add-take on the old one; sharing the
rules is what stops that divergence coming back.

lineage.Path now caps every entry at the head, so hiding the retained
future costs nothing at the call sites: the transcript, the context
builder, attempts.preceding and memory retrieval already funnelled
through path_of and narrow together. Path.uncapped() is the deliberate
exception, and only Redo and the fork check may use it. The memory bank
needs no pruning for the same reason — a memory carries the coordinate of
the node its block ends on, so one derived past the head falls outside
the capped clause and becomes retrievable again on Redo without having
been deleted and re-embedded.

Undo alone does not fork. Moving the head is not a decision to abandon
anything, since the user may be reading or about to Redo; the first write
below the head is where the story states which continuation it means. A
head already at the tip forks nothing, so a story that is never undone
forks exactly as often as it did before and the branch table does not
fill up with one branch per turn. Redo follows the lineage rather than
choosing among branches, which is what invalidates it after a divergence
with no flag to set or clear.

Migrations 78 and 79 give a branch superseded_at and superseded_depth.
Nothing reads them to decide behaviour — Redo is decided by the lineage,
so a stale or hand-edited value here cannot make the story wrong. They
exist so the cleanup and discarded-history features left to a later
version have something to select on, and so a divergence is observable in
a test.

Deleting an action no longer drags a moved-back head forward to the
recomputed tip, which would have silently redone the story. can_undo and
can_redo ride on AdventureOut and ActionPage because the client can work
out neither for itself: the campaign opening may be off the top of the
loaded window, and the retained future is never sent to it.

This is a checkpoint, not the finished milestone. 601 backend tests pass.
Five still assert the destructive contract — they count rows after an
undo and expect the story to be shorter — and need rewriting against the
new one; the world-state assertions inside them already pass. Export and
import do not yet carry the head coordinate, so a bundle still reopens at
the deepest node and can silently redo an undone story, which is the
Phase 0B finding this milestone exists to close. The browser has no Redo
control yet. None of the M3 acceptance coverage (D01-D10, E01-E04,
I01-I03, I07, L01-L02) is written.

JesseMarkowitzandClaude Opus 5 8652fe7cd8 M2 review: two regressions the green suite hid, and the reports
The post-implementation review of M2, plus the three corrections it took
to make the evidence true. Reports:

  planning/reports/M2-BASELINE-REPORT.md        868 lines, the measurements
  planning/reports/M2-IMPLEMENTATION-REPORT.md  758 lines, the reading of them

Verdict is PASS, accept with non-blocking debt, proceed to M3. Every M2
requirement is met and the ones that matter were tested by running the
build rather than reading it: a cloud endpoint written straight into
SQLite with sqlite3, behind the API's back, still refused at the wire;
trusted-LAN HTTPS against the real second machine with verification on;
captures showing zero packets outside loopback and the approved host.

Three defects, all found by running the shipped image.

The memory bank was dead. M2 removed Settings.api_key_plain with the API
key, and memorybank's two provider factories still read it. It failed
inside a fire-and-forget task, so no user error, no log anyone would
read, and no test — every memory test stubs those factories. All 604
tests passed with summaries and embeddings silently not happening.

The configurable model timeout never reached the turn engine. Stored,
validated, exposed in the API, rendered in the UI, and not passed to the
provider. M2's own exit criterion was half met: the constant had moved
but the setting did nothing.

And requirements.lock still pinned quickjs, psycopg and cryptography, so
the setup path DEVELOPMENT.md gives a new developer would have
reinstalled all three.

Both code defects now have the test that would have caught them: one
constructs every provider factory from a real Settings row, one drives
the turn endpoint, the chat endpoint and the summariser and asserts the
configured timeout arrives at each. That is the lesson worth keeping from
this milestone — after removing an attribute, build each consumer from a
real object; after adding a setting, prove it lands. Both failures were
in background or plumbing paths, which is exactly where a subtractive
change cannot see itself.

606 tests pass, up from 604. Lint, build and image are clean. Every
runtime result in the baseline report came from an image built after
these fixes; the reports say plainly that commit 8c65ae9 itself does not
contain them.

Also recorded: 88 test node IDs disappeared and every one is accounted
for — 64 whole files whose subject was removed, 5 replaced by a better
file, 15 individually retired with their features, and 4 renames. No
meaningful coverage was lost, and the eight files that used a JavaScript
counter as instrumentation kept their assertions by moving the counter to
the world-state engine.

Six planning recommendations are reported, not applied. Three are marked
before M3: the threat model still describes the inherited SSRF guard's
opposite rule, TECHNICAL-DESIGN §5.1 still marks two hardening items
open, and the endpoint policy is a load-bearing security decision that
exists only as a module docstring and deserves an ADR.

M3 is clear to start. Its chokepoints are untouched or simplified — the
rollback paths now carry one shared state instead of two — and the Phase
0B undo/redo spike still applies. No M3 work here: Undo still deletes and
there is still no Redo.

JesseMarkowitz 8c65ae99de M2: cut the hosted product away from the local one
94 files, +1,395 -6,578. Three files are new; twenty-four are gone. The
milestone is subtraction, and what is left is the single-user local
storyteller the specification describes.

Removed in full: campaign scripting and its QuickJS sandbox; multi-user
accounts, guest sessions, login, registration and the shared demo key;
the visitor-analytics tables, dashboard and page beacon; the access log
of sign-ins, addresses and devices; per-IP and per-user rate limiting
and quotas; Render deployment config; Postgres and psycopg; cloud
inference providers, the API-key field and the key encryption that
existed to store it; session-cookie signing. None of it was hidden
behind a flag — the routes are gone and answer 404.

Two things were kept that the brief allowed keeping. The `users` table
and its foreign keys stay as an internal ownership detail, because
rewriting them out means a migration across most of the schema to
delete a column that costs nothing; nothing creates a second user and
no request carries an identity. Five inert tables and four inert
columns stay for the same reason, so an M1 campaign database opens
unchanged.

The one addition is app/endpoints.py, which decides where a story may
be sent. Loopback, RFC1918, link-local, unique-local and CGNAT — an
explicit allowlist of networks, not a guess at what `ipaddress` means
by "private", which calls the documentation ranges private and IPv6
loopback reserved. Every address a hostname resolves to must be in it,
so a split answer does not squeak through, and the rule runs both when
the endpoint is saved and before every outbound request, because a name
that resolved to the LAN this morning can resolve elsewhere this
afternoon. Known cloud hosts are named in the refusal so the error says
why rather than looking like broken DNS. TLS is never traded against
it: M1's shared trust context is intact on all four clients and there
is no way to skip verification.

The hardcoded 120-second model timeout is now a setting. That was not
theoretical — on this GPU-less four-core host a cold load of
qwen2.5:3b-instruct took 648.9 seconds to produce the first turn, while
turns 2 to 5 of the same campaign took 3.6 to 13.1. Connect stays short
at 10s so a wrong address still fails fast; the read timeout defaults
to 300s and is bounded at 3600, because "wait longer" must stay a
number.

Two defects found while testing and fixed here. An unknown /api path
fell through the SPA catch-all and came back as HTML with status 200,
so a client asking for JSON parsed a web page instead of learning the
route was gone. And AIDND_CORS_ORIGINS accepted "*", which on an
unauthenticated loopback API would hand every page on the Internet a
write handle on the campaign database; it now refuses to start.

Verified rather than assumed. Offline, on a network with no route out
and no DNS: five turns, retry with both takes retained, restart with an
identical transcript digest, a failed model call leaving the accepted
AI-turn count untouched, and a capture with zero non-loopback unicast
packets. Against a real second machine on the LAN over HTTPS with a
private CA: four turns, restart, and a capture showing 289 packets to
the approved host, 344 loopback, zero anywhere else, zero DNS queries.
Cloud and public endpoints refused with their reasons; no API key
settable; every removed route 404.

604 backend tests pass, down from 648 by the fifteen retired with the
subsystems they tested and up by the twenty-nine added for the endpoint
policy and the removed surface. The scripting tests were not deleted:
eight files used a JavaScript counter as instrumentation for the state
snapshot and rollback machinery, which M2 does not touch, so the
counter moved to the world-state engine and those tests still assert
what they always did. Frontend lint and build are clean; the image
builds, and its wheel-building stage is gone with quickjs.

No M3 work. Undo is still destructive and there is still no Redo.
2026-09-02 11:27:14 -04:00
Claude d72f7c1bda Stop paying twice for a block a retry can still throw away
A memory whose block ends on the newest action is the one memory a player
can reach: retry and take-switching both refuse anything else. Each retry
of that turn withdrew the memory and wrote it again, and a block closes
every six actions while a normal turn writes two, so that was one turn in
three.

SETTLE_SLACK asks for one action past a block before the block is
summarized. The block is still MEMORY_INTERVAL actions; only the moment
moves. This is not the pre-SP4 holdback returning: that one was about a
retry rewriting text in place, which sibling attempts and forget_node
settled, and correctness still rests on the withdrawal rather than on the
slack. Undo and delete can carry a summarized node back to the tip, so the
withdrawal path stays reachable, just rarely.

The slack buys nothing back. The block that just closed is still in the
history window in full, so a memory of it says what the model can already
read.

Tests: the settling suite asserts the new rule and that a retry at the tip
finds nothing to withdraw; the rewrite suite builds thirteen actions so
both of its blocks settle; the one path test that ended on a block boundary
sets the slack to zero, because it is about which actions a block is read
from rather than about when a block forms. 632 green.

Claude 9ee052c51e Give the adventure a persona, so the protagonist has a name
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.

parththakkar106andClaude Opus 5 949f58a054 Sweep the last three uses of the columns SP8 dropped
`seed_demo.py` still passed `index=0` to `models.Action`, which raises
`TypeError` now that the attribute is gone. Every call site inside `app/`
was updated when the column went, but the seed script sits outside the
package and was missed.

`bundle.settle` wrote `memory_cursor` and `summary_cursor`, which are no
longer mapped, so the assignments only set transient Python attributes.
The version 2 branch existed solely to make those assignments, and it ran
two queries per cursor to do it, so it goes. `settle` now returns early
when the bundle carries anchors. The `db` parameter is unused after that.

Also move the comment about deleted memories next to the
`db.delete(branch)` it describes. Splitting the router package left it
after the `finally`, where it read as attached to nothing.

parththakkar106andClaude Opus 5 20f0753277 Merge main into the Phase 17 refactor
`main` changed the four files this branch split into packages, so all four
came back as modify/delete conflicts. Each change is ported to the module
that now holds the code, unchanged in behavior:

- `delete_action` moves to `routers/adventures/actions.py`. It reaches the
  turn lock as `turns.acquire_turn_lock` and `turns._active_turns`, which is
  the rule this branch set: the package root no longer re-exports the names a
  test rebinds.
- `EMIT_RULE` moves to `worldstate/parse.py`, and `_describe_stat` and
  `render_reference` to `worldstate/render.py`.
- The chip-wrap rules move to `styles/schema-editor.css`, and
  `StateChangeChips` to `pages/Play/reports.jsx`. `index.css` keeps this
  branch's import list.

`test_delete_state.py` needed four edits to run here. It drops the eight-line
database prologue, because `conftest.py` does that once now. It imports the
shared `ScriptedProvider` from `fakes.py` instead of carrying a copy. It
patches `adventures.turns.OpenAICompatibleProvider` and reaches the lock the
same way. And it no longer passes `index=0` when it builds the start action,
because migration 71 drops that column.

564 tests pass. `npm run lint` and `npm run build` are clean, and the CSS
bundle is 56.71 kB, which is the pre-merge size plus main's new rules.

parththakkar106andClaude Opus 5 f1bebe18d0 Drop the eight legacy columns SP8 left behind
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.

parththakkar106andClaude Opus 5 2c57b1ceab Remove three kinds of duplication in the backend
Stage 2, items 1, 4, and 5 of `plan/17-refactor.md`.

**One path resolver in `worldstate`.** `apply_delta` and `apply_override` routed
`flags.<name>`, `milestones.<id>`, `world.<stat>`, `player.<stat>`, and
`npc.<id>.<stat>` with parallel code, about 100 lines each. `_resolve` now says
what a path points at and returns either a target or the rejection to report.
Each function keeps its own write rule, because the rules genuinely differ: an
override sets a number rather than adding to it, ignores `cooldown`,
`max_delta_per_turn`, and the rule that a counter only counts up, and can un-set
a milestone.

A differential check ran both implementations over 3960 payloads: twenty paths,
fourteen values, three starting states, plus every three-path combination. The
results are identical except that 674 rejections from `apply_override` now carry
a `fix` string. `apply_delta` already worded those, and the world-state editor
renders them, so an override that names an unknown flag now explains itself the
way a delta does.

**`sse`, `SSE_HEADERS`, and `turn_error` move to `app/sse.py`.** Two routers
stream, and `chat.py` had to import from `routers.adventures` to reach them.

**`get_adventure_or_404` becomes the `current_adventure` dependency.** All 32
handlers repeated the call as their first statement. The ownership check now
reads in the signature and runs before the body. FastAPI caches a dependency for
one request, so the handler's `db` is the session the adventure came from.

The generated OpenAPI document is byte-identical except on `rename_branch`,
where `branch_id` is now listed before `adventure_id`, because that handler no
longer names `adventure_id` itself. Parameter order in the document is
cosmetic.

Six tests in `test_state_revert.py` call `undo_turn` and `retry_action`
directly rather than over HTTP. They pass the adventure they already hold
instead of an id.

549 tests pass.

`backend/app/routers/adventures.py` held 2353 lines and 35 endpoints. It is now

The split moves text rather than rewriting it. An AST comparison against the
old file confirms all 86 definitions are identical, and the OpenAPI schema
still lists the same 35 operations.

Names a test replaces now live in `turns.py` only, and other modules reach them
as `turns.<name>`. Rebinding a re-exported alias changes the alias and leaves
every caller reading the original, so the package root does not re-export them.
A patch aimed at the old target raises `AttributeError` instead of passing while
doing nothing. Tests and the fixtures in `backend/tools/` say
`adventures.turns.<name>`.

The same rule keeps the turn lock working. One module owns `_active_turns`, so
one lock guards one set.
