JesseMarkowitzandClaude Opus 5 ef25b0a876 Stop re-reading the whole prompt every turn, and let a lost run carry on
M01, the hundred-turn campaign, is the one REQUIRED test still
outstanding. Everything here is about it finishing, and being worth
believing when it does. No requirement changed, no acceptance test was
retired or relaxed, and M11 §P.1's "no performance requirement" still
stands: what changed is the cost of a turn, not what a turn contains.

An inference server caches a prompt by its prefix. The history window
gave up its oldest action every turn, which changed the prompt near the
front and threw that cache away, so nearly the whole prompt was
reprocessed every turn however little had actually changed. The window
now snaps the oldest depth to a block and holds it, stepping every few
turns. Measured on real builder output at an 8,192-token budget: 124.0s
per turn against 362.4s. The cost is history depth, bounded by
TRIM_FRACTION at a quarter of the window, which is the dial between
recent history and speed.

A run that dies no longer starts again from turn one. m11_long_run
checkpoints resume.json after the prologue, after every scheduled step
and after every turn, and --resume reattaches to the same campaign. A
finished run deletes it, so the file's presence means an unfinished run
and starting fresh over one is refused. The model timeout is an option
rather than a hard-coded 600s, a turn that overruns is a failed turn
instead of an unhandled exception that ends the run with no summary,
and a run that has stopped producing turns writes its evidence and
stops.

Two checks could not fail. M04's planted clue went into an add_fact
"detail" key that the event does not define, so it was dropped and
fact_still_in_state could never be true; it is now in "value" and
proved at turn one, which stops a run measuring nothing for hours.
m11_browser degraded silently without a narrator into two failures that
read exactly like a product regression, and now requires one, with
--no-narrator as an explicit opt-out that marks the run partial.

Window discovery speaks Ollama's native API, so against vLLM or
llama.cpp's own server the window goes unverified and the budget
uncapped -- M11's own failure mode reached by another route.
context_window_override lets the operator state what they launched the
server with, and is used only where discovery left a hole: a verified
window always wins, so a declaration can lower an unknown ceiling into
existence and never raise a known one. "verified" still means the
server answered, so window_verified in a turn's provenance keeps the
meaning M11's report counts on.

planning/README.md said the M11 tree was staged rather than committed,
in two places; it was committed and signed. Planning package v3.8.

Backend 1,376 passed, 17 skipped, 0 failed; frontend 161; lint and
build clean. Every M11 harness re-run on this tree: browser 38/0/0,
offline 23/0, identity clean, contrast unchanged, recovery 14/0 on a
small bundle. M01 itself has not been run.

JesseMarkowitzandClaude Opus 5 144406cd48 M11: what the server will actually read
The release-validation milestone, and the thing it had to settle first was
whether any of the earlier evidence meant what it said. M8 measured a deployment
enforcing a 4,096-token input window while the application budgeted 16,384.
Every request returned 200. What Ollama does with the excess is drop the oldest
tokens, and the oldest tokens here are the system block — the narrator's rules
and the campaign canon. A hundred-turn certification against that server would
have looked perfect and proved nothing, which is why this milestone could not
begin with a hundred turns.

So the application asks now. Ollama's window is a property of how a model was
loaded rather than of the request — sending num_ctx is accepted, ignored, and
worse, reloads the model at the server's own default — so the only honest move
is to find out and then tell the truth about it. /api/ps reports what a resident
model is being served with, /api/show what an unloaded one will load with, both
on the same host inference already uses, through the same endpoint policy and
the same TLS trust store. A verified window is a ceiling on the budget; an
unverified one leaves the budget alone and is recorded as unverified in the
turn's own provenance, so an old turn can be asked afterwards whether it was
built against a checked window. There is no third behaviour, and in particular
no hard-coded 4,096: a number the server did not say would be right on one
machine and wrong on the next.

The proof that this is doing something is a campaign whose canon sits at the
front of the prompt, 120 turns of history, and a 4,096-token window. The canon
is still there afterwards and the oldest history is gone. The same campaign
built the old way produces a prompt more than twice the window — the defect,
reproduced, so the fix is measured against it rather than asserted.

Two defects the validation found on its own, and they are the same defect twice:
something was true and nobody was told. A manual state correction of four
changes with one bad reference applied three, returned 201, and said nothing —
while recording the refusal on the audit row nobody reads. It came to light
because the identity diagnostic's own fixture was refused that way and the whole
run proceeded on a campaign with no scene, which would have read as a model
failure. And the narration-length setting moved no number: brief, medium and
long each became one English sentence, while the numeric hint the model actually
reads was derived from the global reply cap and said the same thing for all
three. Both now say what they did.

The other two post-M8 findings are closed as well. The tab said AI D&D, which no
document had ever claimed it did not; it says Interactive Story now, with the
open campaign first, and the name is the owner's decision rather than a
find-and-replace to something narrower than the engine. After an Undo the reader
could not tell where they had landed; the control row now ends with
"Moment 11 · later story ahead", from the server's own answer, in the word the
transcript already uses, with none of head, branch or depth anywhere near it.

The identity diagnostic exists and the root cause does not. That campaign was
destroyed, so no cause can be established — what M11 owes the finding is
something that can classify the next occurrence, and a diagnostic that makes only
the judgements a program can honestly make: duplicate keys, shared names,
protagonist drift, state and context disagreeing. Whether prose misattributed a
line is left to a person reading it beside its prompt, because a regex cannot
read dialogue and one that pretended to would produce exactly the confident wrong
answer this finding is about. Its detectors are proved to fire against a planted
second Alice.

Two entities may still share a display name. That was checked first, as the
finding asked, and left permitted: a mother and a daughter, or a stranger giving
a false name, are ordinary fiction, and refusing them to guard against a model
mistake would refuse the wrong thing. What was missing was that it happened
silently. It is reported now.

Evidence, not inference: a hundred accepted turns against a real narrator with
genuine process restarts; a real browser against the built SPA; a container with
no network at all; a campaign moved into a data directory that never existed.
Each was discarded and re-run whenever the product changed under it, and the runs
that were thrown away are listed in the report with the reason, along with ten
defects in the harnesses themselves — because a harness that has only ever
agreed with itself is not evidence, and two of M8's five harness defects were
masking real ones.

No dependency was added, removed or upgraded. No acceptance test was retired,
relaxed or reclassified. M11 is implemented and verified; it is not accepted, and
there is no release tag.

JesseMarkowitzandClaude Opus 5 1013c94eb1 M10: the seam for media, and no media
CI / Backend tests (push) Canceled after 0s
CI / Frontend lint + build (push) Canceled after 0s
CI / Docker image builds (push) Canceled after 0s
The media extension contract asks for a scene snapshot a future image or video
provider could be handed: location, who is present, what they hold, what must
stay true, and where in the story it sits. Building one was the milestone's
obvious first task, and it was the wrong one. That snapshot has existed since
M5. `narrative_state["scene"]` holds the summary, the location, the cast and the
coordinate it was written at; a validated `set_scene` event writes it, every
position snapshots it, and every head move restores it. It survives Undo, Redo,
Retry, divergence, Save Point restore and a process restart because it is the
authoritative state rather than a copy of it.

So there is no scenes table here. A second scene store would have been a second
answer to "where is the story now", with its own lineage rules to get wrong —
and the lineage rules are the expensive part, which is the argument for reusing
the ones that already work rather than against it. The Scene Packet is derived
on read, and its identity is computed from the campaign and the position rather
than allocated: the same position yields the same id in another process, after a
restart, and after the packet is thrown away and rebuilt, with no row to keep in
step. That is the part of a future media_assets table that would be expensive to
retrofit, so it is fixed now even though the table is not built.

One table, then: visual_profiles, the only thing the contract's scene list asks
for that nothing already stored. Campaign-scoped and not per-position, because a
character does not change appearance when the story forks — a reader who
diverged would otherwise lose their cast, and the same descriptors would land in
every per-position snapshot, measured at 245 copies of 367 bytes in a 120-turn
campaign to say something that never varies. Keyed by the M5 entity key rather
than a new identity namespace, and one table for characters, locations and items
alike, because a location is an entity with a type and splitting them would
reintroduce the genre shape M5 spent a milestone removing.

What the packet leaves out is the more interesting half. Not the transcript, and
not imported knowledge — none of it, not merely the sources marked hidden. The
rule is what the story established at this position, not everything the narrator
was told, and drawing it by class is what makes it hold for a secret nobody
thought to mark. A hidden Canon source proves it, with a positive control
showing the narrator did receive the sentinel the packet does not carry. Once a
validated event puts the observer in the room, the observer is in the packet:
that is no longer narrator-only knowledge, and a packet that hid it would be
hiding the story from itself.

The providers are contracts and nothing else. Protocols for image, video, audio,
speech and transcription, an empty registry, no adapter, no dependency, no
socket, and no media setting to point anywhere — a setting that exists can be
pointed at a cloud by mistake. A future provider endpoint must be loopback,
stricter than narration's trusted-LAN allowance, because a picture of a scene
carries the scene with it. Transcription returns an editable draft with no
commit method, so STT structurally cannot bypass the authoritative path.

Nothing here can write the story. Not by convention: no module under media/
imports the code that writes state, no media event type exists in the state
vocabulary, and every test in the authority suite compares the authoritative
document byte for byte either side of a media operation — including one where a
provider insists Alice is in a red coat in a corridor, and the campaign goes on
disagreeing.

One defect, found by the milestone's own tests. M10 first added a migration
creating an index that create_all already builds from the column, so an upgraded
database ended up with two indexes and a fresh install with one. Comparing the
two schemas is what caught it; neither database examined alone would have. The
migration is gone rather than renamed, and the right number of migrations for a
new table whose indexes are declared on its columns is zero.

Backend 1,191 passed / 14 skipped / 0 failed, 89 of them M10's. Frontend 145
passed. Lint, production build and Docker build clean. No frontend file changed:
M10 adds no reader-facing surface, and ordinary play — turns, state, memory,
knowledge, Undo, Redo, Retry, Save Point restore, restart — runs with no media
configuration, no warning, no connection attempt and no media row written.

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 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 d27ee34901 Docs: consolidate active planning and archive historical material
The planning package had grown to where a new agent could not tell what was
authoritative. Phase 0 execution prompts sat beside the specification; four
completed milestone reports sat beside the current one; and upstream AI-DnD's
own `plan/` build log and `docs/` project site still described a hosted,
scripted, multi-user product with accounts — every screenshot in it showed a
Scripts tab and a Sign up button, none of which has existed since M2.

`planning/archive/` now holds the history and says so in its own README:
`phase0/` for the research that chose AI-DnD, `milestone-reports/` for M1 and
M2, `decisions/` for ADR 008, the Phase-0-before-build gate Phase 0 satisfied.
`planning/reports/` holds only the current milestone's report, because that is
the one M4 planning has to read; it moves to the archive when M4's replaces it.

Deleted rather than archived: the Phase 0B execution prompts and the
handoff/status/summary documents, the Phase 0A discovery and triage reports,
upstream's `plan/` and `docs/` trees, and `frontend/README.md`, which was Vite's
template boilerplate. All of it is in Git history, and the two recommendation
reports carry every conclusion the deleted research reached.

Archived documents are kept verbatim. Paths written inside them point at where
those files were when the document was written, which is the point: an evidence
record that has been quietly edited is no longer evidence.

Active documentation is corrected where it pointed at the removed trees or
described removed capability as present. `DEVELOPMENT.md`'s "things M1 did not
touch" list had gone stale at M2 and claimed QuickJS scripting was still tested;
its test count was 604 against an actual 638. `README.md` loses the upstream CI
badge, which reported upstream's pipeline rather than this fork's, and a
reference to `backend/app/worldstate/engine.py`, a file that does not exist.
`planning/README.md` is rewritten as the documentation index.

New: `planning/PROJECT-SOURCES.md` and `planning/project-sources.txt`, the
manifest of what belongs in the ChatGPT project's Sources.

Source comments referring to the deleted trees are reworded; no behaviour
changes. 638 backend tests pass, frontend lints and builds, and a reference scan
over all 48 tracked Markdown files reports no unresolved path in active
documentation.

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.

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.

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 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 e0bf2b61d9 Add a useDebouncedSave hook and delete Settings.stream
Two items from Stage 2 of `plan/17-refactor.md`.

`frontend/src/hooks/useDebouncedSave.js` replaces three copies of the same
debounce. `PlotPanel` and `ScenarioEditor` held identical per-key timer maps.
`ScriptEditor` held a single shared timer, so editing two fields inside the
same 600 ms window canceled the first save. The hook gives every key its own
timer, which fixes that.

`Settings.stream` was dead state. Nothing read it and every turn streams. This
removes the column, both schema fields, and adds migration 65 to drop it. It is
item S1 in `docs/self-review.md`.

Migration 65 needs a new guard. `_column_already_gone` is the counterpart to
`_column_already_there`: `create_all` builds the current schema, which is
already missing every dropped column, so a fixture that stamps an old version
and replays would fail on a column that is not there.

Verified: 549 backend tests pass, lint and build are clean, and migration 65
runs both ways, once against a database that still has the column and once
against one that does not.

parththakkar106andClaude Opus 5 6fa213f6db Group a turn's takes by their parent, not by where they sit
SP7 shipped a tree nobody could use. Driving it by hand found three things,
and the schema is what the third one needs.

A take forked onto its own branch leaves the coordinate its siblings are still
at. `attempts.group` filtered on (branch_id, depth), so that take read as the
only one of its turn -- 1/1 where the player is owed 1/3, with the other takes
unreachable from the line they were taken on. Nesting has the same shape from
the other side: takes under C1 and takes under C2 share a depth, and only the
parent says a pager under C2 reads 2/2 rather than counting C1's three too.

So `actions.parent_id`, and `group` keys on it. The alternative -- pointing a
branch's fork at a node instead of a depth, so a promoted take never moves --
was rejected: `lineage` exists so a read is an OR-clause per branch rather
than a walk up parent pointers, and moving the fork point changes path
resolution itself, which drags in cursors, memory depths and both bundle
formats. This column is read to group takes and for nothing else. One indexed
lookup, never a walk, and no read of the story changes.

Two writers had to learn it. `add_attempt` places a sibling by hand rather
than through `place_action`, and copies the parent, because a take belongs to
the turn it is a take *of*. `place_action` resolves it from the path for a
genuinely new node, which is the honest default.

And one reader had to be kept out of it. `delete_turn` meant "every attempt at
this coordinate"; the group spans branches now, so undoing a turn would have
deleted a take that another branch is telling. `attempts.on_branch` scopes it
back.

409 tests, unchanged from main and green -- a linear story has one take per
parent, so none of this is reachable until a second one exists. The migration
adds one column, backfills the linear case, and leaves NULL where it cannot
honestly place a row; `group` falls back to the coordinate there, which is the
rule those rows were written under. One `VACUUM FULL actions;` owed after
deploy.

parththakkar106andClaude Opus 5 4af6e17406 Answer the review, and keep the opening node's bank
Nine findings from a review of the phase-14 stack. The one about a retry
withdrawing a memory is not a bug — a memory anchored to a node describes that
node, and it goes when the node goes. The root is the exception, and it is the
only one: migration 62 parked every memory written before memories had
coordinates on depth 0, so withdrawing the opening node would retire a whole
bank nobody attached there. A memory with no source range covers no story and
now stays; a summary that genuinely ends there is still withdrawn.

The rest are repairs.

* The adventure list quoted whichever attempt was written last rather than the
  one the story tells, so switching back left the index disagreeing with the
  page.
* A v1 import gave a typed memory no depth, rebuilding the NULL the migration
  exists to remove — invisible until the imported adventure forked.
* The action cap counted a v1 file's turns, and a turn expands into a row per
  saved attempt, so a file inside the cap could write a multiple of it.
* Forking a live node on a borrowed ancestor promoted a sibling on a branch the
  caller never named. It is a branch switch, and now says so.
* Switching attempts left the state, status and memory panels reading the
  previous take: the story does not change length, so nothing keyed on its
  length noticed. Same class as the branch-switch bug this phase already fixed.
* A retry after switching back numbered the new attempt into the middle of the
  group instead of the end.
* The cursor backfill numbered every action in the table once per adventure;
  correlated to the adventure being updated, it is an index lookup instead.
* Renaming a branch answered own_actions=0.

And one behaviour change recorded rather than repaired: script-visible history
and actionCount no longer count blank-text rows. That is the right shape and
there is no reading compatible with both, so plan/14 says so.

409 tests.

parththakkar106andClaude Opus 5 2d38a162d4 Give every memory a node, and show only the ones on your path
A hand-written memory used to carry a NULL depth, described in the model as
"belongs to the adventure rather than to a path". That sounds harmless and
is not: a NULL is a coordinate no fork can cap, so a note typed on one line
followed the reader onto branches whose story it never described. It takes
the head now — the story you were reading when you wrote it — and obeys
exactly the rule a summarised memory obeys.

The unanchored escape clause in lineage.Path.clause existed for that single
case and is deleted rather than left unused. Its docstring argued that a
capped depth would drop a typed memory the moment its branch stopped being
the newest entry; anchoring answers the same worry better, because the
memory is not exempt from the path, it is on one.

The drawer now shows the path being read and nothing else, filtered by the
clause retrieval itself uses, so the bank you can see is the bank the model
can see. Nothing is stranded: a memory lives on a branch, switching to that
branch shows it, and deleting the branch deletes it. Pinning decides order,
the path decides existence.

Migration 62 lands existing NULL-depth memories at depth 0 of their branch
rather than at the tip. 0 is at or before every fork point, so every memory
stays visible from exactly the paths it is visible from today — nobody's
bank loses a row on deploy. The tip is the tidier-sounding choice and would
have emptied them out of every branch forked earlier than they were typed.

This supersedes the on_path flag and the "another branch" badge from
earlier today; anchoring makes them redundant, and they are removed.

Four tests changed because they asserted the old contract, not because
they broke. The one worth reading is the pair replacing
test_a_hand_written_memory_is_not_lost_at_the_first_fork: typed on shared
trunk it still survives a fork, and typed on ground the fork never
travelled it no longer follows you.

402 tests. Verified on tools/branch_fixture.py: each branch's drawer holds
its own memory and not the other's.

parththakkar106andClaude Opus 5 cf3d52171e Let a branch be named, and thrown away
SP7 needs three branch operations and SP5 built one. Switching exists;
naming and deleting had no column and no route between them.

A name is stored because a player chose it. An unnamed branch keeps NULL
rather than a generated "branch 4" — a generated label is derived, and it
would go stale the moment a branch before it is deleted and the ordinals
shift underneath. The client draws those from the fork depth, which
nothing can shift. The v2 bundle carries the name for the same reason it
carries the fork points and leaves `lineage` out: it is a decision, not
something computed from one.

Delete is what stands between a tree and unbounded growth, since nothing
prunes one on its own. It refuses two branches: the root, which holds the
turns every other branch borrows, and the one being read — including any
branch the head was forked from, which is the same mistake in disguise and
the one that would cascade the head away and leave head_branch_id pointing
at nothing. The nodes, memories and descendants go through the foreign
keys that already cascade.

A cursor standing on a deleted branch is cleared. On Postgres a stale
branch id would simply never resolve; SQLite hands the freed id to the
next fork, and then the anchor resolves onto a branch it has never seen
and calls a stretch of story already summarized.

396 tests, 15 new.

parththakkar106andClaude Opus 5 0a12d9cd47 Make a retry a node, not a rewrite
Every attempt at a turn is now its own row at the same (branch, depth),
with `live` naming the one the story tells. The JSON repeating group on
`actions.variants` is read one last time, by a migration that writes it
out as the sibling rows it always described, and then goes unread.

The snapshots turn around with it: an action carries the state it left
behind rather than the state it started from, because attempts at one
turn share a starting position and differ exactly in their outcome.
Rolling back is "what the node in front left behind", one lookup on the
path, and it is what undo and retry now both read.

And the memory holdback goes. It existed because retry rewrote a row
under a mark that had already moved past it; a retry writes a sibling
now, and replacing what a coordinate says withdraws what was derived
from it — the same repair undo and delete already made.

The assembled prompt is still stored once per turn: it moves with the
live flag, so a superseded attempt keeps only the few hundred bytes that
were its own. Measured on the 600-action fixture: 700 rows for the same
600-turn story, prompt archive byte-identical at 0.50 MB, index 1.8 kB
and page load 62.7 kB unmoved.

347 tests green. `tests/test_story_tree_baseline.py` and
`tests/test_retry_variants.py` pass unmodified — SP4 was allowed to move
the baseline for the variant-count semantics and did not need to.

parththakkar106andClaude Opus 5 c51531709d Mark the story with a node, not with a count
The memory bank and the story summary each kept a cursor: how many story
actions they had already covered. A count is a position in a list, and this
list moves — delete an action in front of the mark and every later one slides
down a slot, so the mark now covers one it has never read. All the cursor
bookkeeping existed to patch that up.

Both marks are now (branch_id, depth): the node up to and including which the
work is done. A depth is a coordinate along a path, not an offset into a list,
so nothing in front of it can move it. That deletes rather than rewrites
`position_of_index`, `note_action_removed`, `_rewind_cursors_to_index`,
`prune_dangling_memories` and the every-pass clamp in `run_post_turn`.

A memory hangs off the node its block ends on, so a fork inherits its
ancestors' memories without copying any, and retrieval selects through the
branch clause over the *whole* lineage — recall is long-range by definition and
cannot be windowed. Measured: 1,807 B on a story forked twenty times against
1,823 B on a flat one of the same length.

Migrations 53-56 translate the old counts into nodes. They rewrite `adventures`
and not `actions`, so this one needs no VACUUM FULL.

parththakkar106andClaude Opus 5 d3756abdaa Give every action a branch and a depth
Phase 14 SP1. The tree goes into the schema and nothing reads it yet: a
`branches` table, `branch_id`/`depth` on actions and memories, a head pointer
on adventures, migrations 46-52, and a server-side backfill that re-reads every
existing adventure as a tree with one branch. `depth` holds the number `index`
already held, gaps included, so no story changes — a linear story *is* a tree
with one branch, which is what makes the SP0 baseline passing unmodified the
pass condition rather than a hope.

The writer had to come with it. No migration will ever visit a row written
after it ran, so columns backfilled today and populated next subphase would
leave a hole exactly the width of one deploy, and from SP2 on a row without a
branch is a row no read can see. `app/tree.py` owns that: one module, because a
node written without a branch fails by disappearing rather than by raising.

Three things the schema itself insisted on:

- `adventures.head_branch_id` is a plain integer, not a foreign key. Pointing
  both ways makes the two tables a cycle create_all cannot order, and its
  escape hatch needs an ALTER SQLite does not have. It is a cache, and a head
  naming a branch that is gone recovers onto the root.
- `lineage` is NOT NULL, so the backfill inserts `'[]'` and fills it in a
  second pass guarded on `json_array_length(lineage) = 0` — not `= '[]'`,
  because Postgres `json` has no equality operator.
- SQLite will not drop a column a foreign key names, which is how two existing
  tests broke: they simulated an old database by rewinding the stamp while
  leaving the new columns in place. Every ADD COLUMN migration is now
  idempotent, and `tests/test_tree_migration.py` builds a genuine schema 45 by
  rebuilding three tables from frozen DDL so the real ALTERs run.

297 tests green, 14 of them new. `branches` costs 0.1 kB of a 733.5 kB turn;
page load and index are byte-identical to the recorded figures.

The deploy that ships this needs one `VACUUM FULL actions;` on the direct
endpoint afterwards — it rewrites every row.

uvicorn binds the port, against a database at the other end of a network --
944 rows on production, so a thousand sequential round trips standing between
the deploy and its first health check.

One executemany per batch instead. Same rows, same verification, same
transaction; nineteen round trips rather than nine hundred.

Re-verified on Postgres, since executemany binds bytea through a different
psycopg path: 720,864 B of JSON to 204,293 B, every row equal.

parththakkar106andClaude Opus 5 ae6e5af6c7 Store context_snapshot compressed
One column is 89% of the database and the free tier allows 512 MB. Reads were
already solved -- the column is deferred, so a page load never touches it and
one screen fetches one row at a time -- but nothing had costed storage, and
storage is the constraint with a cliff: 99.6 MB used, ~94 kB of disk per
action, so the ceiling arrives around 5,400 actions and 944 are stored.

Postgres already compresses it and only gets 1.7x. pglz is tuned for fast
decompression of data a query might filter on, and nothing has ever filtered
on an assembled prompt -- it is written once and read whole, rarely, by the
Insights viewer. zlib gets 3.5x on the same text for a decompress on a request
that already made an LLM call.

Done as a TypeDecorator rather than a second column, so every call site still
writes a dict and reads a dict back, and deferred/undefer/load_only keep
naming the same attribute. Only the storage format moves.

Migrations 43-45: add the bytea, convert into it, drop the original, rename.
The backfill is the one destructive step in the file -- 44 removes the only
other copy -- so it decompresses every row and compares it against what went
in, and a row that fails aborts the run. The whole loop is one transaction, so
an abort rolls the DROP back and the prompts are still there.

Verified on real Postgres, replaying 43-45 from a pre-43 schema on a throwaway
Neon database: 720,864 B of JSON became 204,293 B of bytea, 3.53x, the column
came out named context_snapshot, every snapshot compared equal and the one
NULL stayed NULL.

Postgres does not return the disk by itself: DROP COLUMN only marks the column
gone and the backfill leaves a dead tuple per row, so the table peaks near
twice its size before settling. The deploy needs one VACUUM FULL to collect
it; the migration comment says so.

The egress fixture's snapshots are prose now rather than "x" * 20_000, and the
prose generator moved to tools/fakeprose.py so the harness and the tests share
one definition. A repeated character compresses a thousandfold: against the
old fixture a compressed column looked free and the byte ceilings would have
been guarding nothing.

parththakkar106andClaude Opus 5 2c5909a268 Drop the JSON vector column, and fix what was hiding behind it
Migration 38 left memories.embedding in place so a rollback could still find
the vectors. Production has since been verified reading from embedding_blob,
so migration 42 drops it: 4 MB of a 99.6 MB database holding nothing anyone
reads.

Removing it surfaced a live bug. Changing your embedding model is supposed to
throw the bank's vectors away and let the post-turn pass rebuild them, because
two models' vectors are not comparable. The settings route did that by nulling
memories.embedding -- correct until 38 moved the vectors, after which it
cleared the dead column and left the blob intact with `embedded` still true.
_embed_pending filters on `embedded IS FALSE`, so it never saw those rows and
the bank went on ranking against the old model's vectors permanently.

Nothing would have reported it. cosine returns 0.0 on a width mismatch, so a
different-width model scores every memory zero and retrieval returns whichever
rows happen to sort first; a same-width model scores plausible garbage.

The bulk clear now sets both columns. It stays a bulk UPDATE rather than going
through set_vector -- loading the rows is the cost that whole path exists to
avoid -- so set_vector's docstring now names it as the one caller that
legitimately writes those columns by hand. No cache invalidation is added:
clearing `embedded` drops the rows out of the catalogue query, and set_vector
evicts each entry as the re-embed puts it back.

test_embedding_blob.py now rebuilds the pre-38 schema by hand where it tests
the backfill, since create_all no longer produces the column it converts from,
and asserts 42 removes it at the end of a full bootstrap -- 38 reads that
column and 42 drops it, so an upgrade that reordered them would arrive with an
empty bank.

parththakkar106andClaude Opus 5 b7e53ae581 Rank the memory bank without reading the memory bank
Retrieval walked adventure.memories, so every turn loaded every row of the
bank with its vector attached -- 3.1 MB, 96% of everything a turn read. It
now asks SQL which memories are in play (an id and a flag per row), ranks
against vectors held in process, and fetches text only for the five it picks.

Two more callers were doing the same thing and the production SQL could not
see them: _evict_over_capacity walked the bank to count it, and _embed_pending
walked it to find the rows with no vector. Both are counts and filters the
database can do without sending anything back.

    one turn      3,258.7 kB -> 723.4 kB cold, 122.3 kB warm
    run_post_turn 3,139.1 kB -> 0.7 kB
    Insights      3,223.7 kB -> 117.9 kB
    Memories drawer  ~3.1 MB -> 23.6 kB

A played turn is turn plus post-turn work: 6.4 MB down to 123 kB.

The cache needs no invalidation callbacks, which is what makes it safe. A
vector can only change through set_vector, which drops that one entry;
anything that removes a memory from play leaves the catalogue query, and
entries missing from the catalogue are dropped on the next read. So eviction,
deletion and pruning have nothing to remember to call.

memories.embedded joins the blob, for the same reason actions.variant_count
sits beside actions.variants: with the vector deferred, every "is this
embedded?" check would otherwise be a 6 KB lazy load, once per row.

Capacity drops 200 -> 80, on retrieval quality as much as cost -- ranking two
hundred memories to pick five buries the five. Eviction was measured at scale
first: trimming 100 to 80 costs 0.8 kB and reads no vectors.

parththakkar106andClaude Opus 5 c56864877a Store embeddings as packed float32 instead of a JSON list
A 1536-dimension vector spelled out as JSON decimals is ~31 KB. The same
numbers packed as float32 are 6,144 bytes, and the whole bank is read on
every turn, so those bytes are paid over and over.

It is a format change, not a precision trade: the endpoints compute in
float32 and render that into JSON, so converting back recovers the original
bits exactly. Nothing is re-embedded and no API call is made -- migration 38
is a pure repack of what is already stored.

Unlike migrations 36 and 37 this backfill cannot be expressed in portable
SQL, so it comes through Python, batched, and pays a one-time read of every
vector to stop paying three megabytes a turn.

The JSON column stays, still written through set_vector, so a rollback finds
the vectors intact. Reading from the blob comes next; a follow-up migration
drops the old column once that is verified.

Migration SQL can now be a {dialect: sql} map -- BLOB and BYTEA have no
common spelling, and every Postgres deploy replays this one.

parththakkar106andClaude Opus 5 47e33fa311 Read a window of the story per turn instead of all of it
Two reads still grew without bound after the snapshot fix.

`Action.variants` holds every discarded retry attempt, but a list response
only needs how many there are — so each retry permanently added ~5 KB to
every later load of that adventure. Defer the column and keep the count
beside it (migration 37, backfilled server-side), with set_variants() as the
one write path that keeps the two in step.

`story_actions()` walked adventure.actions, then every caller threw almost
all of it away: the builder concatenates the story and immediately cuts it
back to the token budget, the NPC check looks at the last 6, retrieval at the
last 4, the cursor clamp only wants a count. A turn on a 200-action adventure
read 839 KB to use ~70 KB, and grew with every turn played. app/context/
history.py serves those shapes from SQL; window_covering() measures the
actions it fetched and projects how many more it needs, fetching only the
part it does not already hold. Memorybank cursors move to position_of_index()
and settled_count()/settled_slice() — same arithmetic, no full list.

The scripting pipeline still receives the whole history per AI Dungeon's API,
and every helper reuses adventure.actions when it is already loaded, so a
scripted adventure pays what it always did and never twice.

Measured at production shape: retry tax 5.1 KB -> 0; turn 200 839 KB -> 129 KB
and flat from ~turn 50; a 200-turn playthrough 84.5 MB -> 23.0 MB; a delete
115 KB -> 5 KB.

Verified the window builds a byte-identical prompt to the full story across
budgets from 1K to 100K tokens, with and without the retry exclusion - this
is a cost change and nothing else. Cursor helpers checked against the old list
arithmetic, including after deleting a middle action. Counts are real
SELECT count(...): Query.count() wraps the entity select in a subquery, so the
SQL named every deferred column and the egress guard could not tell it apart
from a bulk fetch. 139 tests pass; the four new guards verified by sabotage.

parththakkar106andClaude Opus 5 f1bd099ec8 Cut database egress 189x by deferring the prompt snapshot
The free-tier 5 GB/month network transfer allowance ran out, which blocks
connections outright. The database is only ~55 MB, so 5 GB meant the whole
thing was being pulled roughly 90 times over.

Cause: actions is 39 MB of that 55 MB -- 541 rows at ~74 KB each, almost
entirely context_snapshot, which stores the whole assembled prompt for a
turn. Every adventure load and every turn fetched all of it in order to
read two small things out of it: the world-change chips under an AI
message (Action.world_changes) and the emit block re-attached when
replaying history to the model (_history_text). The Insights viewer is
the only consumer that wants the whole snapshot, and it asks for one
action at a time.

Lifts that slice into its own small actions.world_delta column
(migration 36) and marks context_snapshot, state_before and
world_state_before deferred, so they load only when something touches
the attribute -- Insights, undo and retry, all single-action paths.
The backfill runs server-side, dialect-specific (json_extract on SQLite,
#> on Postgres), because pulling 39 MB of snapshots into Python to
rewrite a slice of each would defeat the purpose.

Measured at production shape (541 actions, 72 KB snapshots), one
adventure load goes from 38.46 MB to 0.20 MB. The traffic that consumed
5 GB would now be about 27 MB.

Deliberately not included: limiting the history query to recent actions,
and removing the redundant db.refresh(adventure) calls. Both were sized
against the old numbers; against a 0.20 MB load they would take ~27 MB a
month down to ~10 MB, which is not worth the complexity.

tests/test_egress.py hooks before_cursor_execute and asserts the emitted
SQL never names the deferred columns during a bulk load, so this cannot
regress silently. 123 tests pass.

parththakkar106andClaude Opus 5 906ba423d8 Keep every retried attempt instead of deleting it
Retry used to delete the last AI action and generate a replacement, so the
discarded narration was simply gone. The row survives now: each attempt is
appended to actions.variants with variant_index naming the live one, and a
ChatGPT-style pager under the message browses them.

Action.text still mirrors the active variant, so the context builder, memory
bank, summarizer and export needed no changes. A variant carries only what
differs between attempts -- the text, the reasoning, and the state it
produced -- never the assembled prompt, which is identical across attempts of
one turn and is the bulk of context_snapshot.

Only the last message can be switched, restoring the script/world state that
attempt produced; earlier turns were written as a continuation of whatever is
active there, so theirs are read-only previews.

Three things that would otherwise bite:

- generate_turn now wraps _generate_turn and watches for a save sentinel. If
  the generator ends without it (provider error, empty reply, script stop,
  client hangup) it re-applies the previous variant -- otherwise a failed
  retry leaves rolled-back stats under un-rolled-back text.
- Retry reuses the turn's own index rather than next_index, or the clock the
  world-state cooldowns run on advances on a re-run of the same turn.
- Editing a message rewrites the active variant too, or paging away and back
  silently reverts the edit.

Migrations 34/35 verified as an upgrade against a populated database, not
just a fresh schema. test_state_revert's retry test asserted the old delete
behaviour and was rewritten.

parththakkar106andClaude Opus 5 aed28d9295 Add "Update from scenario" to pull scenario edits into a running adventure
An adventure copies its scenario's plot text and story cards at creation so
later authoring never disturbs a story in progress. This is the explicit
opt-out, alongside the existing per-script "Sync from library".

GET /adventures/{id}/refresh returns a plan (per-field old/new diff, card
add/update/remove, world-state added/removed paths, and any ${...} answers
still needed); POST applies it under the turn lock so it can't race a
generating turn. The Plot panel shows the plan in a confirm modal first.

Overwrites the plot fields and scenario-derived cards. Deliberately left
alone: the opening `start` action (the story is built on it, and it is baked
into memories and the summary), the adventure's own title and summary,
player-authored story cards, and the live value of every stat the schema
still defines.

Two enablers were needed:

- adventures.placeholders (migration 32). ${...} answers were used once at
  creation and discarded, so re-copying scenario text would have re-injected
  a literal ${Hero}. Adventures predating the column re-prompt once via the
  existing modal, then the answers are saved.

- story_cards.source_ref (migration 33), "card:<id>" / "npc:<key>", NULL for
  player-authored. Adventure cards had no link back to their source, so a
  rename read as delete-plus-add and player cards would have been clobbered.
  Legacy cards name-match once, then adopt the ref.

World state goes through a new worldstate.reconcile(): keep values the schema
still defines, add missing ones at their initial, drop removed ones and their
cooldown bookkeeping. Not instantiate(), which would heal the player to full
and wipe their milestones.

The confirm modal is portalled to <body>: .side-panel's panel-in animation
has fill mode `both`, which makes it the containing block for position:fixed
descendants, so an overlay rendered in place was trapped in the 420px panel
and clipped by its overflow.

14 new tests in backend/tests/test_scenario_refresh.py; 85 pass.

parththakkar106andClaude Opus 5 57c24a07d8 Redesign the library UI and add scenario cover art
Rework the home page into a single landing surface and give the app a
consistent visual language, chosen as "illuminated tome" over two other
pitched directions because it builds on the existing Cinzel + gold identity
instead of replacing it.

Home is now Continue (up to 4 in-progress stories, each showing where you
left off) over a scenario shelf, each section with a "See all" link. The
full adventure list moves to /adventures.

Scenario cover art has three tiers, in precedence order: an uploaded picture
(downscaled client-side to 400px WebP before storing), an emoji, or gradient
art generated from a hash of the title so no card is ever an empty box.
Adventures inherit their scenario's art. Images live in the row rather than
on disk because Render's free tier has no persistent volume, and it keeps
export bundles self-contained; list responses carry a cacheable
/api/scenarios/{id}/image URL rather than the base64.

Also: ambient drifting motes behind the app, loading skeletons, staggered
card entrance, ornamental scene breaks and a drop cap in the story, a
"Weaving" thinking indicator, and a toast system replacing every alert().

Two fixes found along the way:

- Importing a scenario bundle with no "tags" key returned a 500. Column
  defaults are not applied until flush, so the attribute was still None
  when the width clamp sliced it.
- Anything meaning "the story's latest narration" was missing action type
  "start", which is the only text a freshly created adventure has, so new
  adventures looked empty. Collected as NARRATION_TYPES.

Migrations 30 and 31 add scenarios.image and scenarios.icon; both are
additive with a '' default and were verified against a database stamped at
29. vite.config.js now reads AIDND_API_PORT so the recurring port-8000
clash with another local app needs no file edit.

parththakkar106andClaude Opus 4.8 dab1807118 Roll back script_state on undo/retry; fix retry double-apply
The shared per-adventure script_state ("scoreboard" scripts write to) was
never reverted by undo, and retry re-ran the output hook on top of the already-
mutated state, double-applying its changes (e.g. "+10 gold" became +20).

Each action now snapshots script_state as it was immediately before its own
hooks ran (new Action.state_before column, migration 25):
- undo restores the turn's first-action snapshot, prunes memories that
  summarized the removed actions, and takes the turn lock against races.
- retry restores the AI action's snapshot before regenerating.

Story-card mutations are not reverted (documented limit). Adds the project's
first test suite: unit + full HTTP integration through the real scripting
engine (14 tests). See plan/11-state-revert-and-retry-fix.md.
