M11: what the server will actually read

Browse Source 
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.

behind `planning/reports/M11-IMPLEMENTATION-REPORT.md`, and they live in the

"""M11: what the inference server will *actually* accept, as opposed to what we budgeted.
M8 found the failure this module exists to prevent. The application budgets a
prompt up to `Settings.context_token_budget` — 16,384 by default — while Ollama
enforces a window of its own, and on a machine with no VRAM that window defaults
to **4,096**. The request still returns HTTP 200. Nothing warns anybody. What
actually happens is worse than an error: `llama.cpp` drops the **oldest** tokens,
and the oldest tokens in this application are the system block — the narrator
rules and the campaign canon. The symptom is a narrator that forgets canon deep
into a long session, with nothing on screen explaining why, and every acceptance
test that reads a returned 200 as success passing throughout.
The invariant M11 requires:
The application must not silently budget more narrator input
than the configured Ollama runtime will actually accept.
Note the word *silently*. There are two honest outcomes and this module produces
both: either the window is **verified**, in which case the budget is capped to it
so the prompt physically cannot overflow; or it is **unverified**, in which case
the assembly says so, in the context report, on the connection test, and in the
turn's stored provenance. What must not happen is the third thing — assembling
16,384 tokens against a 4,096-token server and calling the result a turn.
## Why this is not solved by sending `num_ctx`
It was tried, and it is documented in `DEVELOPMENT.md`. Ollama's
OpenAI-compatible endpoint accepts `num_ctx` — nested in `options` or at the top
level — returns 200, and ignores it. Worse, it reloads the model at its own
default, so priming the server through the native API first does not help
either: the next request resets the window. The window is a property of how the
model is loaded, not of the request, so the only things that change it are a
model with `num_ctx` baked in (`/api/create`) or `OLLAMA_CONTEXT_LENGTH` on the
server. Both are operator actions. This module's job is not to change the
window; it is to find out what it is and refuse to lie about it.
## How the window is found
Ollama's native API sits beside the OpenAI-compatible one on the same host, so
this asks the server the application is already talking to, and nothing else. No
new destination, the same endpoint policy, the same TLS trust store.
/api/ps a loaded model reports `context_length`: the window the runtime
is enforcing *right now*. This is the truth when it is available.
/api/show an unloaded model may carry `num_ctx` in its baked parameters,
which is the window it will load with; `model_info` carries the
architecture's own ceiling, which caps everything else.
`/api/ps` is asked first because a model that is loaded has already settled the
question. `/api/show` answers it for a model that is not loaded yet, which is the
ordinary case at the start of a session.
## What it deliberately does not do
It does not hard-code 4,096, which would cripple a correctly configured
deployment; it does not raise the budget, which is the operator's decision; it
does not fall back to a cloud probe, a bundled table of model sizes, or a guess
from the model's name. An unknown window is reported as unknown.

"""M11: the application must not silently budget more input than the server accepts.
This is the milestone's release blocker, and the failure it prevents is the
quiet kind. M8 measured a reference deployment enforcing a **4,096**-token window
while the application budgeted **16,384**. Every request returned HTTP 200. What
the server did with the excess is the problem: `llama.cpp` drops the *oldest*
tokens, and the oldest tokens here are the system block — the narrator's rules
and the campaign canon. A 100-turn certification run against that server would
have looked perfect and proved nothing.
So the tests below are in two halves.
**The probe** must find the real window, must refuse to guess when it cannot,
and must be held to the same endpoint policy as inference — a window probe that
could reach an address a turn may not would be a hole in ADR 011.
**The enforcement** is the half that matters: a verified window is a *ceiling*,
and the prompt that comes out of the builder must physically fit inside it. The
sentinel test is the one to read — a campaign whose canon sits at the front of
the prompt, a history far too long to fit, and a small verified window. The
canon must still be there afterwards. That is the difference between the
application choosing what to drop and the server choosing.

That is one of the finding's candidate failure modes.
It is **not** made an error here. Two people called Alice is an ordinary
thing for a story to contain, and refusing it would refuse legitimate
fiction to guard against a model mistake. What M11 adds instead is
*detection*: `nmodel.duplicate_names` reports it, the identity diagnostic

"""M11 §13: E01-E04, all four at once, in one long campaign.
The E-series already has tests, and good ones — M6's corrective pass rewrote E03
after an independent review found the first version passing while the defect was
live. What none of them does is what the M11 brief asks for: exercise all four
**together, in a single campaign, under realistic long-story conditions**, with
state, memories, summaries, imported knowledge and a scene all live at once.
That matters because the four leaks share one mechanism — a head that moves and
a lineage that decides what is still true — and a campaign that has only one of
them cannot show the mechanism failing for one and holding for another. It also
adds the dimension none of the earlier tests could have: M10's Scene Packet, the
thing a future depiction would be built from, which has to answer for the active
line exactly as the state does.
Four sentinels, one per class, each with a positive control on path A and a
negative control on path B:
state a fact and a location established on the abandoned line
memory a distinctive memory extracted from abandoned turns
summary a summary **regenerated after the divergence** (M6-F1's shape)
scene the location the abandoned line moved to, in the state *and* in
the derived packet

"""M11 §17: a fresh install and an upgraded database must be the same product.
M10 found the defect this file makes permanent. It shipped a `CREATE INDEX`
migration for an index `create_all` already built from the column, so an
*upgraded* database ended up with two indexes and a fresh one with a single
index — two schemas differing by which path the file took, which is the thing a
migration exists to prevent. Nothing found it except comparing the two.
So the comparison is the test, and it is written to be general rather than about
`visual_profiles`: every table, every column with its type and nullability,
every index and its uniqueness, every foreign key, and the version stamp. A
future migration that diverges the two paths fails here whatever it is about.
The second half is the upgrade itself: a database built by the **previous
supported build** — M10's schema, version 92 — opened by this one, and then
played, exported and imported, because a migration that leaves a campaign
unplayable has not worked.

"""M11 §E: the context-window fix, against a real Ollama rather than a fake one.
`test_m11_context_window.py` proves the arithmetic and the enforcement with a
mocked server, which is the right place for those. This file answers the
question that a mock cannot: **does the probe read a real Ollama correctly?** The
shapes it parses — `/api/ps`'s `context_length`, `/api/show`'s plain-text
parameter block — are Ollama's, not ours, and a mock built from a misreading of
them would agree with itself forever.
It also demonstrates the sequence a reader actually experiences on a server whose
model has no `num_ctx` baked in:
turn 1 the model is not resident; the window cannot be verified; the
turn proceeds and is recorded as unverified
turn 2 the model is resident, `/api/ps` reports the real window, and the
budget is capped to it from here on
Skipped unless an endpoint is configured, so the ordinary suite stays local,
deterministic and offline. The endpoint is read from the environment and never
written down here.

"""M11 §15 / J01-J03: the same engine, a different genre, no different code.
`TEST-CAMPAIGN-FIXTURE.md` §31 specifies the Persephone Test as the counterpart
to the fantasy Continuity Test, and the claim it exists to check is a structural
one rather than a literary one: **changing genre is configuration, not a code
path**. M5 spent a milestone removing the RPG shape from the state model, and the
way that stays true is a fixture that would fail if any fantasy assumption came
back — a `character`/`location`/`item` triad that cannot hold a ship, a
corporation or an orbital station, a canon check that only understands magic, a
retrieval path tuned to fantasy nouns.
So this file plays the science-fiction fixture through the *same* endpoints,
the *same* state model, the *same* prompt builder and the *same* bundle as the
fantasy one, and asserts on the parts a genre could plausibly break.
The canon is the fixture's, including the three hard-technology rules, and the
run includes the fixture's stated purposes: generic entities, hard canon,
possession, character knowledge and reference retrieval.

"""M11 §20-§21: the release regression, in a real browser, on the frozen build.
python -m tools.m11_browser --out <dir> [--show]
Run from `backend/`, with `frontend/dist` already built. Uses a real narrator
when `AIDND_TEST_ENDPOINT`/`AIDND_TEST_MODEL` are set; the checks that do not
need narration run either way and say which they are.
## What this is and is not
It is the browser half of the release evidence: the M8 workflows re-run as
regression, the security behaviours that only exist in a browser, and the
accessibility properties M8 recorded as *checked by eye* and handed to M11 to
measure. It runs against the **built** SPA served by FastAPI — the production
path from `DEVELOPMENT.md` — because a Vite dev server is not what ships.
It is not a substitute for the component suite, which covers far more states far
faster. What lives here is what jsdom cannot answer: real layout, real focus,
real navigation, a real CSP, a real network stack.
## The rule this harness is built around
M8's review found five harness defects against seven product defects, and two of
the five were *masking* product defects. The lesson recorded there is that a
browser harness asserting on DOM structure, React internals or model wording
produces confident wrong answers. So every check below asserts on something the
product promises — a control's enabled state, a stored value, a request that was
or was not made, a computed style, an accessible name — and never on class names,
element ordering, or the narrator's prose.

"""M11: the multi-character identity diagnostic (post-M8 finding D).
python -m tools.m11_identity # against a real model
python -m tools.m11_identity --scripted # harness self-test, no model
Run from `backend/`. Reads `AIDND_TEST_ENDPOINT` and `AIDND_TEST_MODEL`.
## What this is for
A hands-on session against accepted M8 put four people in one scene — a
protagonist and three others — and later narration treated one of them as two
different people. The campaign was a disposable database and was destroyed, so
**the root cause was never established and cannot be**. What M11 owes the
finding is not a fix for an unknown defect; it is a diagnostic that can tell the
candidate causes apart the *next* time, and evidence about whether the product
does the things it can be blamed for.
`BUILD-MILESTONES.md` names four candidate causes and asks for a classification:
STATE DEFECT the state itself is wrong or ambiguous
CONTEXT ASSEMBLY DEFECT the state is right, the prompt is not
DERIVED MEMORY-SUMMARY DEFECT a summary or memory carried the error in
MODEL FAILURE WITH CORRECT CONTEXT the prompt was right and the model was not
AMBIGUOUS the evidence does not separate them
## How it decides
The objective checks are the ones a program can make honestly, and they are
made against the **stored prompt snapshot** and the **authoritative state**,
before and after every turn:
duplicate entity keys the state model refuses these; a breach is a
STATE DEFECT
shared display names permitted by design, reported by
`narrative.model.duplicate_names`; a new one
appearing mid-scene is a STATE DEFECT for
this scene's purposes
protagonist drift the persona's entity key changing, or the
protagonist disappearing from `present`
state/context disagreement a name in the prompt's state block that the
document does not have, or vice versa
derived contamination the same name appearing under two keys inside
a summary or memory that reached the prompt
Prose-level judgements — did the narrator misattribute this line of dialogue,
did it have a character refer to itself as someone else — are **not** graded
automatically. A regex cannot read dialogue, and a diagnostic that pretended to
would produce exactly the confident wrong answer this finding is about. Every
turn's narration is written out for a person to read, next to the prompt that
produced it, and the tool's verdict says plainly when the objective checks are
clean and the question is therefore about the prose.
## What it preserves
On any signal, everything the finding lists is written to the run directory:
the pre-turn state, the exact stored prompt snapshot, the narration, the
history, summaries, memories, imported knowledge and the model settings. The
campaign is also exported as an M9 bundle, so the whole failing case is
portable and can be replayed on another machine.

"""M11 M01-M04: a real 100-turn campaign, against a real narrator, over HTTP.
python -m tools.m11_long_run --turns 100 --out <dir>
Run from `backend/`. Reads `AIDND_TEST_ENDPOINT`, `AIDND_TEST_MODEL` and
optionally `AIDND_TEST_EMBED_MODEL`.
## Why this is a script that spawns servers rather than a test
M01's pass condition is not "100 requests succeeded". It is **100+ accepted turns
with no continuity, state, history, authority, lineage or recovery corruption**,
across genuine application restarts, with a fact planted at the beginning
recoverable at the end through memory rather than through the transcript.
Three of those words decide the shape of this harness:
*Accepted* — a turn counts when the application committed it, so every turn is
checked for a committed action and a state document, not for an HTTP 200.
*Restarts* — M02 says a new test client, a reconnected browser and a reopened
session do **not** count. So the storyteller runs as a real `uvicorn` process,
started with the command `DEVELOPMENT.md` documents, and is killed and restarted
at planned points. Everything that survives crosses as bytes on disk.
*Recoverable* — the planted clue has to be pushed out of the recent-history
window and then retrieved, so the run measures the window at intervals and the
recall check at the end asks the application what it would actually send.
## What it records
A JSON line per turn (`timeline.jsonl`) with the context measurements M03 wants,
a `measurements.json` of the sampled checkpoints, the recall evidence for M04,
and the final bundle. Everything is written as it happens, so a run that dies at
turn 80 still leaves 80 turns of evidence rather than nothing.

"""M11 §18 and §24: a container with no network, and the packaging path.
python -m tools.m11_offline --out <dir> [--no-build]
Run from `backend/`. Needs Docker.
## Why a container rather than a namespace
§18 asks for a true offline run: fresh data, **no route to the public Internet**,
no external DNS. The obvious tool is an unprivileged network namespace, and on
this machine that is refused — Ubuntu 24.04 sets
`kernel.apparmor_restrict_unprivileged_userns=1`, so `unshare -rn` cannot map a
uid. `docker run --network none` gives the same isolation and more: the
container has a loopback interface and nothing else, no resolver, no route, and
a fresh volume. It also happens to be the packaging path §24 wants exercised, so
one run answers both.
The exercise runs *inside* the container over `docker exec`, because with no
network there is no published port to reach from the host. That is not a
workaround; it is the only honest way to drive an isolated process.
## What an offline run can and cannot prove here
Everything that does not need a model: first page load, the SPA's own assets,
campaign creation, a story turn's *attempt*, knowledge import and retrieval,
export, import into a fresh campaign, restart, and the M10 media module
importing and staying inert.
Inference is **not** exercised offline, and the report says so rather than
implying otherwise. This deployment's Ollama is on another machine on the
trusted LAN, which `SECURITY-THREAT-MODEL.md` §73 permits and which is not an
Internet dependency — but it is also not reachable from a container with no
network. What the offline run proves about inference is the useful half: with no
model reachable, the application degrades to a reported error and the campaign
stays intact.

python -m tools.m11_recovery --bundle <path> --out <dir>
Run from `backend/`. Takes the bundle the 100-turn run exported.
M9 proved the bundle contract with `test_m9_clean_import.py` — two processes,
two directories, nothing crossing but the file — against a fixture campaign
built to break a round trip. What it could not do is prove it against **a
campaign nobody designed**: a hundred real turns, real narration, real state the
model proposed, real summaries and memories, and whatever the history operations
left behind. That is what this does, and it is the only I-series evidence that
uses the release candidate's own long-run output as its input.
The destination is a database file that has never existed, in a directory that
has never existed, opened by a second server process. Migrations run there from
nothing, so this is the fresh-install path as well as the import path.

"""A W3C WebDriver client in one file, so browser evidence needs no dependency.
M8 and M9 drove Firefox from a harness that lived outside the repository, which
made their browser evidence unrepeatable by anyone else. This is the same thing
kept inside it, and deliberately dependency-free: WebDriver is an HTTP protocol,
`urllib` speaks HTTP, and adding Selenium to the release candidate to press
buttons would put a package in the audit surface (§23) for no capability.
Only what the release scenarios need is implemented. Anything missing is missing
because nothing used it, not because it was hard.
**One environment note, established by measurement.** Firefox here is a snap, and
its sandbox refuses a file the browser was told to open from `/tmp` — which is
what M9 recorded as "this machine cannot drive a file into the browser". The
narrower and more useful statement is that it refuses `/tmp`: a path under the
user's home works. `stage()` exists to put evidence files there, so knowledge
import can be exercised through the real file input rather than in two halves.

release polish; `V1-ACCEPTANCE-TESTS.md` §P1 records what must be settled before
this can become an acceptance test.
#### As implemented (M11)
The candidate above, built. A status line sits at the end of the story-control
row and reads `Moment 12`, gaining `· later story ahead` whenever the server
says Redo is available:
```text
Continue Retry Undo Redo Save Point Moment 11 · later story ahead
```
Three properties, because they are what make it answer §8A rather than merely
occupy the corner:
- **It is the server's answer, not the browser's.** The number is the count of
actions on the active line as the server reports it, and "later story ahead"
is `can_redo`. A component that decided either for itself would be wrong
exactly when it mattered — Undo can reach past the loaded window.
- **It changes visibly.** After an Undo the number decreases *and* the clause
appears; both are asserted, in the component suite and in the browser
regression, because a requirement that a working implementation can satisfy
while the reader is lost is the requirement §8A replaced.
- **It uses no implementation vocabulary** (§38): not head, not branch, not
depth. `Moment` is the word the transcript already uses for the same thing
("Read the 12 earlier moments"), so it introduces no new concept.
Evidence: `frontend/src/m11.test.jsx` ("finding B") and the `B` rows of

## Status: IMPLEMENTED AND VERIFIED — 2026-09-07, awaiting independent review/acceptance
Implemented on `m11-release-validation` from the signed M10 commit `1013c94`.
`planning/reports/M11-IMPLEMENTATION-REPORT.md` is the evidence package, written
for a release reviewer. **M11 is not marked accepted here**; that is the
reviewer's to record, and no release tag exists.
**The release blocker it was given, and how it was closed.** M8 measured the
reference deployment enforcing a **4,096**-token input window while the
application budgeted **16,384** — every request returning 200, and `llama.cpp`
dropping the *oldest* tokens, which in this design are the narrator's rules and
the campaign canon. A 100-turn certification against that server would have
looked perfect and proved nothing.
M11's invariant: *the application must not silently budget more narrator input
than the runtime will accept.* It now asks the server — `/api/ps` for a loaded
model, `/api/show` for one that is not — under the same endpoint policy and TLS
trust as inference, and caps the prompt to what it finds, or records the window
as unverified in the turn's own provenance. Not a hard-coded 4,096, which would
cripple a correctly configured deployment; not a guess from the model's name.
Measured on the reference server: the plain model reports 4,096 and the budget
caps to it; the `num_ctx`-baked model reports 16,384 and the full budget stands.
**The four post-M8 playtest findings, disposed of:**
| | Disposition |
| --- | --- |
| **A.** The tab read `AI D&D` | **Fixed.** `Interactive Story`, with the open campaign first — a name chosen by the repository owner, and deliberately not "Adventure Storyteller", which is narrower than a genre-agnostic engine. One module owns it. |
| **B.** No orientation after Undo | **Fixed.** `Moment 11 · later story ahead`, from the server's own answer, in the transcript's existing vocabulary, with no implementation words. `BROWSER-UX-SPEC.md` §8A records the implementation. |
| **C.** Narration length had no effect | **Fixed.** The choice is data (`adventures.narration_length`), and the prompt builder turns it into a real word band. The generation budget is deliberately untouched: capping it would truncate prose, and the state block is emitted last. |
| **D.** Character identity confusion | **Diagnostic built; root cause remains unestablished, as it must.** The campaign was destroyed. `tools/m11_identity.py` runs the finding's own scenario, makes only the judgements a program can make honestly, preserves everything on a signal, and proves its detectors fire. The structural fact the finding asked M11 to check first — two entities may share a display name silently — is now **reported** rather than refused, because two people called Alice is ordinary fiction. |
**Two product defects found by the release validation itself**, both the same
family — something true that nobody was told:
1. **A partly refused manual state correction reported success.** Four changes,
one refused, HTTP 201, nothing said. Found because the identity diagnostic's
own fixture was refused that way and ran on a degraded campaign without
noticing. The refusal was already on the audit record; the reader was not
told. Now returned as `refused`, and shown in the State panel.
2. **The narration-length setting** above, which is finding C.

## 28B. What M11 Added (as implemented)
One column, and one field on a response. Both exist because something that was
happening silently had to become visible.
```text
adventures.narration_length "" | "brief" | "medium" | "long"
```
The campaign's own narration-length choice, and the *only* schema change M11
makes. Until M11 the choice became one English sentence inside
`ai_instructions` and moved no number: the numeric hint the model actually reads
was derived from the global reply cap and said the same thing for all three
settings. Stored as its own field because the prompt builder has to derive a
word range from it (`context.builder.LENGTH_BANDS`), and reading a length back
out of free text would be a parser nobody wants. Empty is not a missing value —
it is a campaign that never chose, which is exactly what every campaign created
before M11 did, so the migration needs no backfill and no existing prompt
changes under it.
**No new table.** The context-window ceiling M11 enforces is *not* stored: it is
asked of the server, cached in the process, and recorded in the turn's context
snapshot as provenance. A stored ceiling would be a second copy of a fact the
server owns, going stale the moment an operator reloads a model — the same
argument M10 made against a scenes table.
**`duplicate_names` is derived, not stored** (`narrative.model.duplicate_names`).
Two entities sharing a display name is permitted — a mother and a daughter, a
stranger giving a false name — and until M11 it was also *invisible*, which is
one of post-M8 finding D's candidate failure modes. It is computed from the
entities on read and reported beside the state.
**`refused` is per-response, not persisted.** A manual correction that is partly
refused now returns which of its changes did not apply and why. The refusals
were already recorded on the proposal row for §8's audit trail; what was missing
was telling the person who wrote them, who until M11 got an unqualified success.

## 42B. M11 Release Validation Notes
Three things M11 changed or measured that belong in this document. **None widens
the trust boundary**; two narrow what can happen silently, which is this
document's own concern (§56 story secrets, §69 auditability).
**The context-window probe is a new outbound request, and it is held to §73.**
`app/contextwindow.py` asks the configured Ollama for the window it will give a
model. It is the same host inference already uses, on the sibling native path,
through the same `endpoints.rejection_reason` check and the same TLS trust union
— so it can reach exactly what a turn can reach and nothing else. A probe that
could resolve an address inference may not would have been a hole in ADR 011, and
it is asserted not to be
(`test_m11_context_window.py::test_a_probe_obeys_the_same_endpoint_policy_as_inference`).
**A silently partial state correction was a §69 auditability gap.** A manual
correction of four changes where one was refused returned an unqualified success:
the refusal was recorded on the proposal row for the audit trail, and the person
who made it was told nothing. The correction response now carries `refused`, with
the reason. Partial application itself is unchanged and deliberate — discarding
three good changes because of one typo would be worse — what changed is that the
reader is told.
**H09 is NOT APPLICABLE, and the condition is now a test.** §59's Zip Slip
concern applies "if ZIP import/export is implemented". Nothing in the
application opens an archive — the bundle is JSON, an imported source is a single
file — and `test_m11_security.py::test_h09_the_product_extracts_no_archives`
fails the day that stops being true, at which point H09 becomes required again.
**Measured, not assumed:** every text/background pair in the palette clears WCAG
AA 1.4.3 (`tools/contrast_audit.py`, lowest 5.02:1). Two control-boundary pairs
are below 1.4.11's 3:1 and are recorded rather than failed, because in this
design a control is identified by its visible text label — which is measured and
passes — and not by its edge. That is a judgement stated so a reviewer can
disagree with it, not a threshold quietly lowered.

### 15.2 The inference window is a ceiling, not an assumption (M11)
M8 measured a reference deployment enforcing a **4,096**-token input window while
the application budgeted **16,384**, and every request returned HTTP 200. The
consequence is worse than an error: `llama.cpp` drops the *oldest* tokens, and
the oldest tokens in this design are the system block — the narrator's rules and
the campaign canon. A long campaign would quietly stop obeying its own canon,
and every acceptance test that reads a 200 as success would keep passing.
M11's rule:
> The application must not silently budget more narrator input than the
> configured Ollama runtime will actually accept.
`app/contextwindow.py` asks the server, on the same host and under the same
endpoint policy as inference: `/api/ps` reports the window a **loaded** model is
being served with, and `/api/show` reports the `num_ctx` an unloaded one will
load with plus the architecture's ceiling. The answer is cached per endpoint and
model, so it costs one short request per session rather than one per turn, and
it is cleared when either changes.
The builder takes the window as a parameter — like retrieved memories and
imported passages, and for the same reason: the prompt builder makes no network
calls. A **verified** window is a ceiling on `context_token_budget`; an
**unverified** one leaves the configured budget standing and is recorded as
unverified in the turn's stored provenance, on the context report, and on the
connection test. There is no third behaviour, and in particular there is no
hard-coded 4,096: guessing a number the server did not say would be right on one
machine and wrong on the next.
What this does not do is change the window. That is an operator action — a model
with `num_ctx` baked in, or `OLLAMA_CONTEXT_LENGTH` — and `DEVELOPMENT.md` says
how. What the application owes the reader is not to lie about it.

program can make honestly — duplicate keys, shared display names, protagonist
drift, state/context disagreement, derived contamination — preserves everything

attribution is for a person to read, because a regex cannot read dialogue and a
diagnostic that pretended to would produce exactly the confident wrong answer
this finding is about.

than product; the product changes it did make were each forced by something the
validation found.

**The release blocker M11 was given, and what it cost.** M8 measured a
deployment enforcing 4,096 tokens while the application budgeted 16,384, with
every request returning 200 and `llama.cpp` silently dropping the oldest tokens —
which here are the narrator's rules and the campaign canon. M11 makes the
application ask the server what it will accept and cap itself to that, or say
that it could not check. Not a hard-coded number, not a cloud probe, not a
guess from the model's name: `/api/ps` for a loaded model, `/api/show` for one
that is not, under the same endpoint policy and TLS trust as inference.
**Two product defects found by the validation itself**, both of the same
family — something true that nobody was told:
- a **manual state correction that was partly refused** returned an unqualified
success. Found because the identity diagnostic's own fixture was refused that
way and the run proceeded silently on a degraded campaign;
- the **narration-length setting moved no number** (post-M8 finding C), so the
numeric hint the model reads said the same thing for brief, medium and long.
**Zero requirement weakenings.** No acceptance test was retired, relaxed or
reclassified. H09 is reported NOT APPLICABLE on the condition its own text
states, and that condition is now enforced by a test.
