SP7 replaced the pager with chips, on the grounds that a chip could also offer
"take this path" while a pager could only step. Driving it by hand said
otherwise, and the reason is worth keeping: the chip meant two different
things depending on where the reader was standing -- a real switch at the tip,
a preview needing a second button above it further back. Two meanings in one
control is what made the tree unusable.
So: one control that does one thing. Stepping reads a take and nothing else,
and it tells the server nothing, because reading is not a decision. The
transcript below a take that is not live simply ends -- such a take is a leaf
by construction, since whatever was played after the turn was played after the
take that *is* live. The decision is made by writing, and `after_id` carries it.
One step does reach the server and is still not a fork: a take with a story of
its own lives on its own branch, so going there is a branch switch and only the
server can say what is underneath. `branch_id` on the take is what tells the
two apart without asking first.
And a fork button on every turn but the opening. On the AI's it regenerates; on
your own it opens the text so you can say something else. What the story made
of the old take is kept, on the line it was written on.
`selectVariant` and `forkFromAttempt` leave the client. Both endpoints stay --
tested, and `stand_on` is shared with the write path -- but the pager needs
neither.
426 backend tests; lint and build clean. Not yet driven by hand: the frontend
still has no test runner, so this needs the `--keep` fixture and eyes, exactly
as SP7 did.

`retry` only ever saw the last action: mid-story there was no way to ask for
another take at all. Now the take endpoint takes either kind of node, and the
kind decides what happens -- an AI turn regenerates, a player turn takes the
text supplied. The client asks the same way for both.
The tip is the only case that needs no branch, and only for an AI turn, where
the takes are still leaves nobody has built on. That is the existing retry,
reached by another road. Everywhere else `branch_at` leaves the path just
before the turn so the story after it keeps the take it was written for.
Both paths roll the shared state back to before the turn ran, which the fork
endpoint was already doing and the player-take path was not -- a script would
otherwise have stacked this take's output mutations on the one being replaced.

`2/4` needs the shape of a turn's take group for every message on screen.
Asking `attempts.group` per row would put a query behind each one -- the exact
cost `variant_count` was cached to avoid, and the reason SP8 could not just
drop that column and be done. So one query per page, keyed on the parents the
page mentions, and the count and ordinal land on the rows before they are
serialised.
`take_count` / `take_index` rather than reusing the old pair, because they do
not mean the same thing: the old ones cache a coordinate's siblings and say 0
for a turn nobody retook, these count the *turn's* takes across whatever
branches they ended up on and say 1/1. SP8 still drops `variant_count` and
`variant_index`.
Two traps, one of them mine. `parent_id` was not in ACTION_LIST_COLUMNS, so
reading it off a windowed row would have been a lazy load per action -- an
N+1 hidden behind the thing `load_only` exists to prevent. And the adventure
GET does not build `ActionOut` at all: it hands the window to the relationship
with `set_committed_value` and lets Pydantic walk it, so patching the three
places that do build ActionOut missed the one path every page load takes.
The test caught it by reading the wire instead of the helper.

Retry has always given an AI turn another take. Nothing gave one to the
message the player wrote, so the only way to change something you had typed
was to overwrite it -- destructively, losing whatever the story made of it.
That is the half of the tree the player asked for first, and it never existed:
`POST /actions/{id}/fork` answers 400 unless a second take is already there,
so "branch from here" was not a thing the API could do.
`tree.branch_at` is the missing piece. `fork` moves a node that already exists
onto a line of its own; this is the same branch with nothing in it yet, for a
take that has not been written. The head lands one depth short, so the next
node written is the new take -- same depth, same parent, resolved from the
path by `place_action` without being told. The line being left keeps its node,
keeps it live, and keeps everything played after it. Nothing is copied.
Two things the tests said rather than confirmed. A player turn is never the
tip: the reply to it is, so retaking even the newest thing typed still owes a
branch, and the guard against forking for nothing only fires for a player
action with no reply under it. And player text is stored formatted, so a test
that compares it whole is testing the formatter.
421 tests.

Stepping between takes used to be two controls and two meanings. At the tip a
chip switched; above the tip it only *previewed*, and taking that line needed a
second button next to it. Which one you got depended on where you were standing,
which is the thing that made the tree unusable when it was driven by hand.
So the server stops caring that anyone is looking. Reading a take the story
moved past changes nothing and creates nothing. `ActionCreate.after_id` names
the node a turn is played after, and naming a take the story left is the first
moment the player has said which line they mean -- so that is where the fork
happens, and only there.
`stand_on` is the old fork endpoint's body, lifted out whole. It already knew
the two cases and got them right: at the tip the takes are leaves nobody built
on, so it is a switch and no branch is made; past the tip the line being left
keeps every turn it has, so the take needs a branch. Both callers now share it,
which is the point -- a fork asked for and a fork arrived at are the same move.
Six tests. Five fail with the grouping reverted to the coordinate, and the one
that does not is deliberate: naming the tip in `after_id` must stay an ordinary
turn that forks nothing, which guards against over-correcting rather than
against the original bug. The nesting test passes both ways too and is kept for
what it says, not for what it catches -- a coordinate separates C1's takes from
C2's by accident, because the fork has already put them on different branches.
415 tests.

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.

Retrieval has been path-scoped since SP3: a memory on a branch this story
never travelled is never sent to the AI. The drawer listed every memory
alike, so on a fork you read "Fell down the cellar stairs; badly hurt" and
reasonably concluded the model knew it. It does not. That is worse than
either hiding the row or retrieving it — it is the screen claiming
something the engine contradicts.
Hiding them is not the answer either; that was the original comment's
point, and it stands. A memory nobody can list is a memory nobody can
delete, in a phase whose rule is that nothing is removed automatically.
So the whole bank still lists, and the rows off the current path are set
back, dashed, and labelled "another branch". MemoryOut.on_path carries it,
computed from the predicate retrieval itself uses rather than a second
spelling of the same idea — two spellings drift, and the failure mode here
is a badge that says the opposite of what the model gets. Pinning does not
override it: the path clause runs before pinning is considered.
The relationship is asymmetric and there is now a test that says so. A fork
borrows its ancestors, so a memory written on the parent is on the fork's
path too; the reverse never is. Worth pinning before somebody makes it
symmetric on the grounds that it looks wrong.
399 tests, three new, egress ceilings intact — the flag costs one id-only
query. Verified in a browser on tools/branch_fixture.py.

The pager could only step between attempts, and stepping has nothing to say
about the thing the tree exists for: taking a path the story moved past and
keeping both. Every attempt has been its own node since SP4, so a chip is a
node now, and "take this path" forks — or simply switches, when the turn is
still the tip and its attempts are leaves nobody has built on.
Beside it, a Branches panel: every line the story has taken, with where each
left its parent and where it ends, and switch, rename and delete-with-confirm.
It sits with Plot/Memory/Scripts/Insights rather than inventing a new place to
put a rail. An unnamed branch is drawn from its fork depth, never from its
position in the list — a position shifts the moment a branch above it goes.
A spatial per-node map was considered and deliberately not built. At the size
this has to be verified against it is a second windowing problem, and it can be
added later without a new endpoint, since the rail and a map read the same
GET /branches. VariantOut grows an id because a fork is addressed by the node
being taken, not by an ordinal in a group that renumbers.
Driven by hand against the 602-action fixture, which found one bug that no test
could: the panel refreshed on actions.length, and a fork swaps a 60-action
window for another 60-action window, so it went on drawing a one-branch tree
while the story was already on the second. It keys off the counter adoptWindow
bumps now.
The scroll path was driven at the same time — three prepends of ~16,200 px, the
same node holding viewport top 792 to 787, never thrown to the end. That closes
the standing gap in this project. Console clean.

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.

Attempts pile up at the tip as leaves and cost nothing. The moment the
player takes the story down one the line has already moved past, the two
futures have to coexist — so `tree.fork` gives that attempt a branch of
its own, forked at the depth just before it, and the line it leaves
keeps every turn it has.
One row is inserted and one row is moved. Nothing is copied: everything
before the fork is borrowed through the lineage cached on the branch
row. Measured on a 40-turn story forked twenty times — 21 branches, 140
rows, an 80-action story — the page load costs 31,652 B against the
31,433 B the same story flat costs, and a branch is 103 B of ancestry.
Nothing derived moves either, and that is the part worth keeping: a
memory hangs off the coordinate the parent's attempt still occupies, and
the lineage caps the parent one depth short of it. The fork simply
cannot see it, so it resummarizes that ground from the text it actually
tells, without a line of bookkeeping.
Two things had to change underneath. A new node's depth now comes from
the tip of its branch rather than from the adventure-wide `index`, which
would have left a hole in a fork's path the width of the other branch.
And undo stops at the fork — the turns before it belong to the branch
this one grew out of.
`GET /branches`, `POST /branches/{id}/switch` and
`POST /actions/{id}/fork` are the endpoints SP7's tree view is drawn on.

Opening a finished adventure fetched every action in one response: 589.5 kB on
production's longest, and nothing about that curve bends on its own, because a
story only ever gets longer. The page load now brings the newest 60 actions
and the reader pages up from there. On the harness's 600-action fixture that
is 606.0 kB down to 62.6 kB, and -- the part that matters -- it no longer
depends on how long the story is.
Paged by anchor, not by offset. `before_id` is the oldest action the caller
holds; the server returns what precedes it. An offset counted back from the
newest would shift every older position the moment a turn lands, which is
exactly when someone is likely to be scrolling, and the reader would get one
action twice and never see another. It also keeps working when the story stops
being a flat list: comparing indices to order a branch survives the story tree,
treating them as positions does not.
`has_more` comes from fetching one row past the window rather than from
counting. A deleted anchor -- undo, mid-scroll -- reports the end rather than
guessing and serving a page the reader already has.
GET /{id}/actions and POST /{id}/undo now return {actions, total, has_more}
instead of a bare list. Undo is the action most likely to be repeated several
times running, so having it re-fetch the whole story would have undone the
paging on the worst case.
The adventure payload gets its window through set_committed_value rather than
by assignment: the actions relationship cascades delete-orphan, so assigning a
60-item list to it would delete everything outside the window on the next
flush.
In Play.jsx the prepend is followed by a useLayoutEffect that restores the
scroll position, before paint, so the story does not jump. Loading starts 400px
from the top rather than at it, guarded by a ref because scroll fires far
faster than React re-renders. There is a button as well as the scroll trigger:
on a short viewport the transcript may not be tall enough to scroll at all, and
a reader who cannot scroll must still be able to reach the beginning.
Verified against a running backend and a 220-action adventure: the page load
returns 60 of 220 ending on the newest, and walking back from an anchor returns
exactly the actions before 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.

Models like DeepSeek V4 Flash reason by default, and the reasoning budget
setting could only ever add thinking tokens - there was no value that turned
thinking off. A negative budget now sends `reasoning: {effort: "none"}`.
Uses effort:none rather than exclude:true deliberately - exclude still thinks
and still bills, it only hides the trace.
Zero keeps its old meaning (send no `reasoning` field at all) so endpoints that
reject unknown fields, like the default Ollama one, are unaffected. Reusing the
existing int column this way avoids a migration.

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.

AI Chat is a plain scratchpad for talking to a model directly — no story
context, scripts or world state — for poking at models, prompts and endpoints
without starting an adventure. Power users only: the router 404s (rather than
403s) for everyone else and the nav link is hidden. The conversation lives in
localStorage, so there's no new table or migration.
is_power_user() now also returns True in local mode: it's the operator's own
machine and their own key, the same reasoning that makes the provider debug log
local-only.
Alongside that, the rule keeping the shared demo key off paid models now lives
in exactly one place. It had been duplicated into the chat router, which is how
one copy eventually drifts:
- resolve_provider_config() takes an optional model_override and is the only
place the whitelist is applied, so turns, AI Chat and the connection test all
inherit it. An override is a per-request preference, never a grant.
- ProviderConfig.__post_init__ refuses to exist when api_key is the demo key
and the model isn't whitelisted. It keys on the key itself rather than the
using_demo flag, so a mislabelled config can't slip past, and it raises so a
future path that bypasses the resolver fails loudly instead of billing.
- The demo branch still pins endpoint_url too — a user-controlled endpoint
would leak the key itself, which is worse than spending it.
Provider gained chat(messages, ...) beside generate(), both delegating to a
shared _stream(url, body); completion-mode endpoints get the messages flattened
into a labelled transcript. Settings' /models fetch moved to
list_endpoint_models() and is shared with /api/chat/config.
Tests: 10 new in tests/test_chat.py (70 total). These deliberately do not stub
resolve_provider_config — the point is to exercise the real BYOK-vs-demo
decision and assert on what the provider actually received: off-whitelist
override pinned, off-whitelist Settings.model pinned, redirected endpoint
pinned, BYOK passed through untouched.

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.

- AdventureScript.source_script_id links a copy to its library Script
(migration 24; set at adventure creation)
- list endpoint flags out_of_date by diffing copy vs library
- POST /adventures/{id}/scripts/{sid}/sync overwrites the copy's code,
