WP-A1 and WP-A2, implemented in sequence, plus the corrective work the owner
asked for at review. Reported in
planning/reports/v1.1/V1.1-WP-A1-A2-REPORT.md (corrective addendum §R).
Planning package v4.2.
WP-A1: context-window safety reserve
- The prompt leaves max(256, ceil(5% of the effective window)) tokens free
beside the reply. That is 256 at 4,096 and 820 at 16,384. The value is fixed,
not a setting, and not calibrated per model.
- M6's 64-token margin is gone. Separators and the chat hint are priced
exactly; tokenizer drift is the reserve's job.
- Protected context that cannot fit raises ContextOverflow before the model
is called.
- Streams set stream_options.include_usage. Measured on Ollama 0.33, a stream
sent no usage without it.
- Each sent turn records fits, exceeded, truncation_suspected or unknown.
The status is returned on the done event, logged when bad, and shown in the
context inspector. The turn is always kept.
- Accounting is per-attempt data (attempts.ATTEMPT_KEYS).
- Corrective: a cold model is loaded before its turn is built. When the
window is unverified but the server answered, contextwindow.ensure_window
makes one bounded POST /api/generate naming only the model. It sends no
prompt, generates nothing and writes nothing. It then probes again, and the
turn is built to that answer. If the load fails, or the window is still
unknown, the turn falls back to the old behaviour.
- Real host, 4,096 window:
- v1 cold turn: sent 13,875, the server read 2,050.
- Same turn after the correction: the window was verified, 3,082 sent,
3,097 read, fits, 499 tokens left beside the reply.
- Verified turns elsewhere left 275-2,297 tokens against v1's 23-42.
WP-A2: protocol echo and genre-neutral state prompting
- The vocabulary is shown as the JSON object the model sends, not as
name(field, ...). This costs 121 tokens.
- The example uses character-1, item-1 and location-1.
- The extractor removes shapes anchored to application-owned text:
- a vocabulary call line;
- an echoed length hint;
- the renderer's scene line left last;
- an empty fence opener.
- Corrective R5: the echoed continue hint is recognised by its own sentence
("Output only story text"). A Hard-limit-opened bracket is removed only
directly above an echo already cut from the same reply.
- Replay of all 518 real v1 replies: 9 changed, 0 flagged, and no story prose
removed. That is unchanged by R5.
- Replay of 64 v1.1 replies: 3 changed, 0 flagged. The depth-16 instruction
tail is removed.
- Identity diagnostic after the correction:
- 0 identity signals;
- 0 prompt example identifiers proposed;
- 0/10 stored turns with protocol or instruction shapes.
- 50-turn run: 51 accepted, 0 of 54 stored turns carry protocol.
- SPECS, render.py and validate.py are identical to v1.0.0.
Compatibility: a real v1.0.0 database reads identically on v1.0.0 and v1.1,
field for field, with schema and user_version 94 unchanged. Undo, redo, Save
Point restore, export and import all work on it. There is no schema,
migration or bundle-format change.
Verification: the backend suite passes 1,534 with 17 skipped and 0 failed.
The frontend passes 165/165, and lint and the build are clean. The offline
container and the browser regression were re-run on this tree (see §R.3).
One test was re-calibrated, not weakened: test_history_block_trim's prefix
test had assumed which turn holds the floor at a 2,048 budget.

# ADR 013 — The Authoritative Narrative State Document
|
|
|
|
**Status:** Accepted; implemented in M5
|
|
**Date:** 2026-09-04
|
|
|
|
## Context
|
|
|
|
[ADR 010](010-explicit-typed-narrative-state-events.md) settled the **protocol**:
|
|
the model proposes change as explicit, typed, absolute events drawn from a fixed
|
|
allowlist, never as relative deltas. It did not settle what those events write
|
|
into.
|
|
|
|
That shape turned out to be load-bearing. The prompt renders it, the browser's
|
|
state panel groups it, export carries it, migration has to produce it for
|
|
positions that predate it, and every Undo, Redo, take switch and Save Point
|
|
restore reads a copy of it. The M5 review recommended recording it as a decision
|
|
rather than leaving it an implementation detail of `narrative/model.py`. This ADR
|
|
records what was built; it does not extend it.
|
|
|
|
## Decision
|
|
|
|
### The document
|
|
|
|
One JSON document is the campaign's authoritative account of its own story. It
|
|
is genre-neutral: nothing in it names a stat, a level, a currency or a class.
|
|
|
|
```text
|
|
entities who and what exists — people, places, things, groups.
|
|
Each carries a name, a type, aliases, a description, a status,
|
|
free-form attributes, conditions, and a current location.
|
|
facts what has been established, as subject/predicate/object.
|
|
Each carries an id, a status, and where it came from.
|
|
relationships how entities stand to one another, directionally.
|
|
possessions which entity holds which item.
|
|
threads open story threads, with a title and a status.
|
|
scene where the story is now, and a short summary of the moment.
|
|
```
|
|
|
|
Two fields appear throughout and are the reason the document can be trusted:
|
|
|
|
- **authority** — who established this: the story, or the reader's own
|
|
correction. A reader's correction outranks the narration, and the prompt says
|
|
so in words.
|
|
- **provenance** — the branch and depth the change was made at, so a fact can be
|
|
traced to the moment it entered the story.
|
|
|
|
Nothing is deleted. A fact a correction takes back is marked `invalidated`, with
|
|
the reason and the position, because a record that vanished would audit nothing.
|
|
|
|
### The pipeline
|
|
|
|
```text
|
|
model output
|
|
-> extraction the protocol block is separated from the prose
|
|
-> validation envelope, allowlist, schema, references, canon
|
|
-> validated events recorded in `state_events`, with their provenance
|
|
-> the document applied to produce the new authoritative state
|
|
-> per-position snapshot stored on the node the turn produced
|
|
```
|
|
|
|
Each stage has one job, and the order is deliberate: the allowlist is checked
|
|
before any field is read, so an unknown event type is rejected before its
|
|
contents are touched.
|
|
|
|
**Implementation note (post-M11).** "The protocol block is separated from the
|
|
prose" covers more than one fenced block. A small local model also pastes the
|
|
rendered state into its prose, writes its proposal unfenced or quoted, and runs
|
|
out of tokens partway through it. All of that is removed before the prose is
|
|
stored, because stored prose is replayed as history. `TECHNICAL-DESIGN.md` §15.4
|
|
has the rules.
|
|
|
|
**Implementation note (v1.1 WP-A2).** A small model also copies the protocol's
|
|
*instructions*: the vocabulary written as calls, the length hint, and the scene
|
|
line. The fix is on both sides:
|
|
|
|
- **Prompt:** the vocabulary is shown in the wire format, and the fixed example
|
|
uses genre-neutral placeholders.
|
|
- **Extractor:** it recognises those echoes only by strings and names the
|
|
application owns.
|
|
|
|
No event type, field, validation rule or proposal record changed.
|
|
`TECHNICAL-DESIGN.md` §15.4 lists the four rules.
|
|
|
|
### Where it lives
|
|
|
|
- `adventures.narrative_state` — the current authoritative document. This is
|
|
what the narrator is told and what the reader is shown.
|
|
- `actions.narrative_state_after` — the whole document as it stood after that
|
|
position played, on **every** node.
|
|
- `state_events` / `state_proposals` — the audit: what was proposed, what was
|
|
accepted, what was refused and why.
|
|
|
|
### What each is for
|
|
|
|
**Event history is audit and provenance, not a source of truth.** Restoring a
|
|
position never replays it. This was proven by renaming the table away
|
|
mid-campaign: Undo and Redo continued to work.
|
|
|
|
**Snapshots are what make restore bounded.** Arriving at a position is a single
|
|
row read whose cost does not grow with the length of the story (ADR 012 §10.4).
|
|
A position without a snapshot is a position the head cannot be restored to, so
|
|
every node has one — including nodes written before M5, which migration 88
|
|
backfills with the empty document. A missing snapshot restores the empty
|
|
document rather than leaving the previous position's state standing.
|
|
|
|
**The document is the authority; the model only proposes.** Every event, whether
|
|
it came from the model or from a reader's correction, passes the same
|
|
validation. The model cannot write a field directly, cannot invent an event
|
|
type, and cannot refer to an entity that does not exist in this campaign.
|
|
|
|
## The invariant
|
|
|
|
```text
|
|
visible active transcript position == stored head == authoritative state
|
|
```
|
|
|
|
Everything above exists to hold this. The M5 review found two ways it had been
|
|
broken — a narrator edit that rewound live state while the head stayed at the
|
|
tip, and a restore to a migrated position that left a later position's state
|
|
standing — and both were fixed by making the rule absolute rather than by adding
|
|
a special case.
|
|
|
|
## Consequences
|
|
|
|
- The document is larger than the RPG dict it replaced, so both it and the
|
|
per-node snapshots are stored compressed.
|
|
- Genre lives in the campaign's canon and in the words the story uses, never in
|
|
the schema. A science-fiction campaign and a fantasy one produce the same
|
|
shapes.
|
|
- A reader's correction is durable and outranks narration, and the prompt states
|
|
both what holds and what has been withdrawn.
|
|
- Export carries the document, the canon and every snapshot. It does **not**
|
|
yet carry `state_events` / `state_proposals`, so an imported campaign keeps a
|
|
correction's effect but not its audit trail. Deferred to M9.
