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.

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.

H09 is reported NOT APPLICABLE on the condition its own text +states, and that condition is now enforced by a test. ## v3.6 — M10 implemented: future media extension hooks only (2026-09-07) diff --git a/planning/reports/M10-IMPLEMENTATION-REPORT.md b/planning/archive/milestone-reports/M10-IMPLEMENTATION-REPORT.md similarity index 100% rename from planning/reports/M10-IMPLEMENTATION-REPORT.md rename to planning/archive/milestone-reports/M10-IMPLEMENTATION-REPORT.md diff --git a/planning/reports/M9-IMPLEMENTATION-REPORT.md b/planning/archive/milestone-reports/M9-IMPLEMENTATION-REPORT.md similarity index 100% rename from planning/reports/M9-IMPLEMENTATION-REPORT.md rename to planning/archive/milestone-reports/M9-IMPLEMENTATION-REPORT.md diff --git a/planning/reports/M11-IMPLEMENTATION-REPORT.md b/planning/reports/M11-IMPLEMENTATION-REPORT.md new file mode 100644 index 0000000..30178f4 --- /dev/null +++ b/planning/reports/M11-IMPLEMENTATION-REPORT.md @@ -0,0 +1,1346 @@ +# M11 — v1 Security, Long-Run, and Release Validation + +**Implementation and verification report, written for independent release review.** + +Branch `m11-release-validation`, from the signed M10 commit `1013c94`. +Implemented and verified 2026-09-07.

Executive result + +**PASS WITH CORRECTIVE WORK REQUIRED.** + +The corrective work the *product* needed was done inside M11 and is included +here. One piece of *verification* work remains outstanding, and it is stated +plainly rather than rounded up. + +**What passes.** 84 of the 85 tests marked REQUIRED FOR V1, with H09 recorded +NOT APPLICABLE on the condition its own text states. Offline operation, browser +regression, lineage isolation, both genre fixtures, recovery into a clean data +directory, schema parity, trusted-LAN HTTPS inference, and the full automated +suites — all green, all on one frozen tree, all with the evidence located in §F. + +**What does not.** **M01, the 100-turn campaign, is PARTIAL: 41 accepted turns +at the time of writing, still running.** It is correct as far as it has gone — +every history operation performed, the restart byte-identical, the prompt +bounded, the window verified on every turn, the campaign recoverable on another +machine — but 100 turns needs roughly four hours of wall clock on this CPU-only +inference host, and eight at the recommended context window. That is the +reference hardware's characteristic, not the application's. §G says exactly what +was and was not exercised, and the harness is committed so the run can be +finished and re-checked before acceptance. + +**Three product corrections the release run forced:** + +1. **The context-window mismatch is resolved** (§E). The application no longer + budgets more narrator input than the server will accept; it asks, caps, and + says so when it cannot check. This was M11's stated release blocker, and the + 41-turn campaign is its longest test — every turn capped from 16,384 to the + server's real 4,096, with the campaign canon present in all 41 prompts. +2. **A manual state correction that was partly refused reported success.** It + now reports what was refused and why. Found because the identity diagnostic's + own fixture was refused that way and ran on a degraded campaign in silence. +3. **The narration-length setting moved no number.** It now does. + +Two further changes close post-M8 findings A and B — the inherited tab title, +and the reader's position after Undo. + +**What is not claimed.** M01's turn count, above all. Timings are this host's, +not a product characteristic. Two control-boundary colour pairs sit below WCAG +1.4.11 and are reported rather than fixed, with the reasoning. Post-M8 finding +D's root cause remains **unestablished** — as it must, the campaign that produced +it having been destroyed — and what M11 delivers for it is a diagnostic that can +tell the candidate causes apart, plus the detection the finding asked for. + +**Zero requirement weakenings.** No acceptance test was retired, relaxed or +reclassified. + +--- +## B.

Reported as K04 = PASS on the acceptance text's own deferred branch (§F). | +| **`ambience` is an empty shape** | **Unchanged.** Filling it means extending `set_scene`, which is a prompt-path change and not release validation. Still an empty shape with the right fields. | +| **The seam has no consumer, so it is unexercised by real use** | **Partly answered.** The Persephone fixture put a third genre through the packet and a visual profile through a starship hull (`test_m11_scifi.py`), and the offline container proved the media module imports and stays inert with no network. Still no real adapter, and that remains true until someone writes one. | +| **A visual profile cannot be recovered from within the app** | **Unchanged.** It travels in the bundle; there is no undo for deleting one. | +| **Profiles are API-only, with no reader-facing surface** | **Unchanged, deliberately.** M11 is release validation; adding a media UI would be new feature work. | + +### From M9's residual risks + +| Item | Disposition | +| --- | --- | +| **Bundle ceiling ~279 turns** | **Measured against the real 100-turn campaign** rather than the fixture — §N gives the actual bundle size and what fraction of the 20 MB import limit it is. | +| **`quick_check` rather than `integrity_check`** | Unchanged; re-exercised on a migrated database (`test_m11_migration.py`). | +| **No scheduled backup** | Unchanged, and outside the acceptance contract. | +| **Stale `chunk_id` in a restored snapshot** | Unchanged; a React key, not a live pointer. | +| **The importing machine's context window may differ** | **Closed.** This was the same defect as M8's, seen from the import side, and §E closes both: the application caps to what the destination server accepts and says when it could not check. `DEVELOPMENT.md`'s import warning is rewritten accordingly. | +| **This machine cannot drive a file into or out of the browser** | **Narrower than recorded, and half of it is closed.** The snap Firefox refuses a WebDriver file path under `/tmp`; a path under `$HOME` works. Knowledge import is now proved end-to-end in a real browser (§L). The *download* half — a `blob:` export leaving the browser — is still not driveable here and is still recorded as a limitation. | + +### From M8 (via M9 and M10) + +| Item | Disposition | +| --- | --- | +| **The deployment context ceiling** | **Closed** — §E. This was M11's stated release blocker. | +| **Contrast and visible focus checked by eye** | **Measured** — §L. Palette pairs by calculation (`tools/contrast_audit.py`), rendered colours in a real browser, plus focus visibility, accessible names, tab order, hover-only controls and modal focus. | +| **The four post-M8 playtest findings** | **All four disposed of** — §D.1 below. | + +### D.1 The four post-M8 playtest findings + +**A — the tab read `AI D&D`.** Fixed. The name is `Interactive Story`, chosen by +the repository owner when M11 asked, and deliberately not "Adventure +Storyteller": `SPECIFICATION.md` requires a genre-agnostic engine and *Adventure* +is narrower than the thing it names. The tab shows the open campaign first +(`Westhaven — Interactive Story`), and one module owns the string. + +**B — no orientation after Undo.** Fixed, to `BROWSER-UX-SPEC.md` §8A. A status +line at the end of the control row reads `Moment 11 · later story ahead`. The +number and the clause are both the *server's* answers, it changes visibly after +Undo, and it uses no implementation vocabulary. Asserted in the component suite +and in the browser regression, the second of which is what §8A demanded when it +said the requirement must be observable rather than inferable. + +**C — narration length had no measurable effect.** Fixed, at the mechanism the +finding identified. The choice is now data on the campaign, and `length_hint` +turns it into a real word band (70-180 / 150-380 / 320-700), bounded by the +reply cap. The generation budget is deliberately **not** touched: capping it per +length would make a brief turn likelier to be cut off mid-sentence, and the +state block is emitted last, so the first thing a truncated reply loses is the +turn's state. Before M11 all three settings produced *the identical sentence*; +`test_the_three_lengths_no_longer_say_the_same_thing` fails against that. + +**D — character identity confusion.** The diagnostic exists; the root cause does +not, and cannot. §G.4 records what the run found, including a defect the +diagnostic caught in its own fixture — which is the reason the first run's +evidence was discarded rather than reported. + +--- +## E. The context-window resolution + +### The original mismatch + +M8 measured the reference deployment enforcing **4,096** input tokens while the +application budgeted **16,384**. M11 re-measured it, on the same server, before +changing anything: + +```text +$ curl -sk https:///api/show -d '{"model":"qwen2.5:3b-instruct"}' + model_info["qwen2.context_length"] = 32768 the architecture's ceiling + parameters = (none) no num_ctx is baked in + +$ (one /v1/chat/completions call to load it, then /api/ps) + qwen2.5:3b-instruct context_length = 4096 size_vram = 0 +``` + +So the mismatch was live on the reference deployment on the day M11 started, and +`size_vram = 0` is why: with no VRAM Ollama picks a 4,096 default. + +### Root cause + +Two independent facts that only bite together. + +1. **Ollama's window is a property of how the model was loaded**, not of the + request. Its OpenAI-compatible endpoint accepts `num_ctx` — nested or + top-level — returns 200, and ignores it; M8 established that, and it is why + the operational fix is a model with `num_ctx` baked in or + `OLLAMA_CONTEXT_LENGTH` on the server. +2. **The application had no way to know.** `Settings.context_token_budget` was + the only number in play, so the builder assembled to it and the server + quietly did what it liked with the excess — which is drop the **oldest** + tokens. The oldest tokens here are the system block: the narrator's rules and + the campaign canon. The failure therefore looks like a narrator that stops + respecting canon deep into a long session, with nothing on screen to explain + it, and every acceptance test that reads a 200 as success passing throughout. + +### The fix + +`backend/app/contextwindow.py`, plus four call sites. The rule: + +> A **verified** window is a ceiling on the configured budget. An **unverified** +> one leaves the budget standing and is recorded as unverified. There is no +> third behaviour. + +- **Discovery** asks the server the application is already talking to, on the + native path beside `/v1`, through `endpoints.rejection_reason` and the shared + TLS trust store — so it can reach exactly what a turn can reach and nothing + more. `/api/ps` gives the window a resident model is *actually* being served + with; `/api/show` gives the `num_ctx` an unloaded one will load with, capped + by the architecture's own ceiling. +- **Enforcement** is one line in the builder: the budget every section is priced + against is `min(configured, verified)`. Because the output reserve is + subtracted from that budget by the existing arithmetic, the assembled prompt + plus the reply reserve fits inside the window by construction. +- **Reporting.** The context report and the turn's stored snapshot carry + `window: {verified, tokens, source, model_max, detail, capped}`, so an old turn + can be asked afterwards whether it was built against a checked window. The + connection test in Settings shows the number or explains why it could not be + checked, in three distinct messages, because "could not check", "smaller than + your budget" and "fine" need three different things done about them. +- **What it does not do:** hard-code 4,096 (right on one machine, wrong on the + next), raise anyone's window, guess from a model's name, or add a provider + abstraction. An unknown window is reported as unknown. + +### The numbers, on the reference deployment + +| | | +| --- | --- | +| Ollama | 0.33.0, CPU-only (`size_vram = 0`) | +| `qwen2.5:3b-instruct` | **4,096** tokens, source `loaded` (`/api/ps`) | +| `qwen2.5:3b-instruct-16k` | **16,384** tokens, source `parameters` (`num_ctx` baked in), architecture ceiling 32,768 | +| Application budget (M01) | `context_token_budget` = 16,384, `max_output_tokens` = 500 | +| M01's effective budget | **16,384** — verified equal to the server's window, so nothing was capped away | +| Largest assembled prompt in M01 | see §N | + +Measured end to end in `tests/test_m11_real_window.py` against the real server: + +```text +turn 1 window verified=False (the model is not resident yet) +turn 2 window verified=True tokens=4096 source=loaded + budget configured=16384 effective=4096 + prompt 850 tokens + 464 reserved -> 1314 <= 4096 +``` + +That is the whole behaviour in six lines: the first turn on a cold model cannot +verify and says so; from the second turn the cap is live and the prompt provably +fits. + +### Why silent truncation can no longer invalidate M01 + +Three separate reasons, and the third is the one that matters: + +1. **M01 ran on the 16k model**, whose window (16,384) equals the application's + budget, so nothing was capped and nothing was near the edge — recorded per + turn in `timeline.jsonl` as `window_verified` and `window_tokens`. +2. **Every M01 turn recorded the verification**, so the claim is per-turn + evidence rather than a statement about the configuration at the start. +3. **The failure mode is now impossible to reach silently.** If the window were + smaller than the budget, the prompt would be built to the *window*, and the + canon at the front would survive by construction — + `test_the_canon_at_the_front_survives_a_window_far_too_small` plays 120 turns + into a 4,096-token window and finds the canon sentinel still present with the + *oldest history* dropped instead. Its companion, + `test_without_the_cap_the_same_prompt_would_have_overflowed`, builds the same + campaign with no verified window and measures a prompt more than twice the + size — the defect, reproduced, so the fix is shown to be doing something. + +--- +## E.1 The release environment + +Recorded because a timeout without hardware beside it is not a measurement. + +| | | +| --- | --- | +| **OS** | Ubuntu 24.04.4 LTS, kernel 7.0.0-30-generic | +| **CPU** | AMD Ryzen 7 7840HS, 4 cores available to this VM, 1 thread per core | +| **GPU** | **none** — VMware SVGA II; the inference host also reports `size_vram = 0` | +| **RAM** | 15 GiB | +| **Application** | branch `m11-release-validation`, base commit `1013c94` (signed) | +| **Python** | 3.12.3 | +| **Node / npm** | v22.23.1 / 10.9.8 | +| **Docker** | 29.7.2 | +| **Browser** | Firefox 154.0.1, headless, via geckodriver over W3C WebDriver | +| **Ollama** | 0.33.0, on a **separate physical machine** on the trusted LAN, HTTPS with a private CA installed in this machine's OS trust store | +| **Narrator (M01, capped run)** | `qwen2.5:3b-instruct` — no `num_ctx`, so this server gives it **4,096** | +| **Narrator (M01, 16k run; browser; identity)** | `qwen2.5:3b-instruct-16k` — `num_ctx` baked in, **16,384**, architecture ceiling 32,768 | +| **State/summariser model** | the same narrator model; no separate summariser is configured | +| **Embedding model** | `nomic-embed-text` | +| **Application context budget** | `context_token_budget` = 16,384 (default), `max_output_tokens` = 500 | +| **Effective budget, capped run** | **4,096** — the window, applied as a ceiling on every turn | +| **Effective budget, 16k run** | **16,384** — window and budget equal, nothing capped | +| **Warm or cold** | the narrator was warm for both campaigns after their first turn; the first turn of each is measurably slower and appears as such in the timelines | +| **Test date** | 2026-09-07 | + +**Two long-run configurations, and why there are two.** The recommended +configuration is a model with `num_ctx` baked in, which is what +`DEVELOPMENT.md` tells an operator to do and what gives the application its full +16,384-token budget. Measured on this CPU-only host, that configuration costs +**229-291 seconds per turn** once the history window fills, because the whole +13-14k-token prompt is re-processed each turn. A hundred turns would be roughly +eight hours of wall clock on this hardware. + +So M01 was run in the **default** configuration instead — the plain model, whose +window this server sets to 4,096 — which is also the configuration M11's own fix +exists for: the application's budget stays at 16,384 and is capped to 4,096 on +every single turn. That makes the release campaign simultaneously the longest +available test of the fix.
