# Planning Package Version

- **Package:** Adventure Storyteller Planning Package v4.2
- **Revision date:** 2026-09-14
- **Status:** **v1.0.0 released on 2026-09-14**: the signed tag `v1.0.0` and `main` both point at the signed release commit `432f041`. Milestones M1-M11 complete and closed; all 82 REQUIRED FOR V1 tests pass, with H09 not applicable. **v1.1 is in progress** on `v1.1-development` (`V1.1-PLAN.md`): **WP-A1 and WP-A2 are implemented and staged for owner review.** No other work package has started, and no v1.1 version or tag exists.

## v4.2 — WP-A1 and WP-A2 implemented (2026-09-14)

Two v1.1 work packages, implemented in sequence. No requirement or acceptance
test changed, and no schema or bundle format changed. Evidence is in
`reports/v1.1/V1.1-WP-A1-A2-REPORT.md`.

| Document | Change | Kind |
| --- | --- | --- |
| `TECHNICAL-DESIGN.md` §15.2 | **As implemented (v1.1 WP-A1)**, covering: the safety reserve, `max(256, ceil(5%))`; what replaced M6's 64-token margin; the server's own count; the four accounting states; and keeping the turn. | as-implemented record |
| `TECHNICAL-DESIGN.md` §15.4 | **As implemented (v1.1 WP-A2)**: the vocabulary shown in the wire format, genre-neutral placeholders, and extractor rules R1-R4, each anchored to application-owned text. | as-implemented record |
| `DECISIONS/013-authoritative-narrative-state-document.md` | An implementation note for v1.1. No event type, field, validation rule or proposal record changed. | as-implemented note |
| `V1.1-PLAN.md` | Status: A1 and A2 implemented and staged. | status |
| `planning/README.md` | Current state. | index |
| `reports/v1.1/V1.1-WP-A1-A2-REPORT.md` | **New.** The combined review package, with A1 and A2 kept separate. | work-package report |
| `README.md`, `DEVELOPMENT.md` | The reserve and the accounting. The stale backend test count and the Screenshots paragraph are corrected. | developer docs |

**Corrective work before commit (owner review, 2026-09-14).** Report §R.

| Document | Change |
| --- | --- |
| `TECHNICAL-DESIGN.md` §15.2 | A cold model is loaded once before its turn is built (`contextwindow.ensure_window`). |
| `TECHNICAL-DESIGN.md` §15.4 | R5: the echoed continue hint is recognised by its own sentence, and the application-opened tail above it is removed. |
| `DEVELOPMENT.md`, `README.md` | The cold-model load, in operator terms. |

**Requirement changes: zero.**

## v4.1 — Post-release correction, and the v1.1 plan (2026-09-14)

Documentation only. No product code, no requirement, no acceptance test and no
schema changed.

**Part 1 — post-release correction.** v4.0 was written before three owner
events that have since happened: the closeout commit was signed (`432f041`),
`main` was fast-forwarded to it, and the signed tag `v1.0.0` was created on it
and pushed. The current-state wording that said otherwise is corrected. The M11
report is not edited: its §T records the state at closeout, which was true when
written.

| Document | Change | Kind |
| --- | --- | --- |
| `README.md` | Status: v1.0.0 released; tag and `main` at `432f041`; v1.1 on `v1.1-development`. | developer docs |
| `planning/README.md` | Current state, the release events, the map (v1.0.0 released, v1.1 planning), the stop rule restated for work packages, `V1.1-PLAN.md` in the document table and reading order. | index |
| `planning/BUILD-MILESTONES.md` | Header status, **stale since M8** ("M9 is next"), now says complete and closed. A dated post-release note under M11's status, leaving the closeout paragraph as it stood. The *Post-v1 backlog* points at its triage. | milestone status |
| `planning/VERSION.md` | This header and entry. | package version |

**Part 2 — the v1.1 plan.**

| Document | Change | Kind |
| --- | --- | --- |
| `planning/V1.1-PLAN.md` | **New.** Every post-v1 backlog item and every other recorded v1 residual risk, triaged. Six v1.1 work packages in order (A1, A2, B, C, D, E), each with objective, rationale, scope, non-scope, affected subsystems, acceptance criteria, regression requirements, dependencies, compatibility and risk. The v1.1 release criteria. A v1.2 list and future work. | planning |

**Recommended scope: a focused v1.1.** Context-window safety, protocol-echo
hardening, independent memory retention, browser coverage, recovery honesty and
control-boundary contrast. Scheduled backups, identity-diagnostic extensions and
media adapters are deferred, with the reason for each.

**First brief to write:** WP-A1, the context-window safety reserve.

**Requirement changes: zero.** Every v1.1 package improves the implementation of
an existing requirement, so `SPECIFICATION.md` and `V1-ACCEPTANCE-TESTS.md` are
unchanged.

## v4.0 — M11 closeout: v1 release validation accepted (2026-09-14)

No requirement change, and no product code change. The closeout re-ran the
black-box evidence on the exact release-candidate tree, `3652dc6`. Its product
code is identical to `96c1bf5`, where the 100-turn evidence was taken. The
browser, offline and identity runs had last been run on `ef25b0a`.

| Document | Change | Kind |
| --- | --- | --- |
| `reports/M11-IMPLEMENTATION-REPORT.md` | **New §S**: the closeout's exact-tree verification, including the identity diagnostic's results, which the report had never carried. **New §T**: the acceptance record. **Corrections**: the REQUIRED FOR V1 count is 82, not 85 (the 85 counted four SHOULD rows and left out H09), and §L's browser narrator was `qwen2.5:3b-instruct`, not the `-16k` model. §A, §B, §D.1, §F (A06, G01), §L, §O, §P and §R now reflect the closeout. | milestone report + corrections |
| `BUILD-MILESTONES.md` | **M11 marked COMPLETE / ACCEPTED.** A *Post-v1 backlog* section records work that is not a milestone. | milestone status |
| `V1-ACCEPTANCE-TESTS.md` | **§P V1 Release Gate gains its result.** The §P3 M11 disposition now records the diagnostic's run. | acceptance evidence |
| `planning/README.md` | Status, milestone map, stop rule, and why the M11 report stays in `reports/`. | index |
| `README.md` | One status sentence: v1 release validation passed; not yet tagged. | developer docs |
| `backend/tools/m11_browser.py` | **Harness fix.** G01's import wait could not fail, because the campaign's own title contains "hidden". It now waits for the imported source's row. | release-test infrastructure |

**What the closeout found.** No release blocker. One harness defect, fixed. Three
non-blocking observations, all from the identity run on a 4,096 window:

- the extractor leaves event-call syntax and a parroted length hint in stored
  narration;
- the state rule's fixed example carries fantasy slugs, which the model copied;
- the state lagged the narration.

The owner chose on 2026-09-14 to carry the extractor gap as a residual risk
rather than change product code. Report §S.4.

**Requirement changes: zero.**

## v3.9 — M11's long-run evidence, and the two defects it took to get it (2026-09-14)

No milestone, no requirement change, and no acceptance claim. M01 was the one
REQUIRED test v3.8 left outstanding. It now has a complete 100-turn run on commit
`96c1bf5`, and M01-M04 pass on it. Getting there found two product defects and
five harness defects. The M11 report's revision (`d198806`) is the evidence.

| Document | Change | Kind |
| --- | --- | --- |
| `V1-ACCEPTANCE-TESTS.md` | **Result blocks for M01-M04**, citing the evidence run. **Correction:** v3.7 said this file carried results for the M11 release run against every REQUIRED test. No such blocks were written. The per-test matrix is the M11 report's §F. The M11 disposition under §P3 also said the report records the identity diagnostic's findings; it does not, and the disposition now says so. | acceptance evidence + correction |
| `BUILD-MILESTONES.md` | **M11 status block** gains the long-run evidence and the two further product defects. | milestone status |
| `TECHNICAL-DESIGN.md` | **"Background failure observability" gains the write-lock rule.** **New §15.4**: stored narration carries story only. | as-implemented record |
| `CONTEXT-AND-MEMORY.md` | **§51 gains what M11 found**: a derived failure has to be recordable, and must not be caused by the turn itself. | as-implemented record |
| `DATA-MODEL.md` | **§28B corrected.** M11 added two columns, not one. `settings.context_window_override` (migration 94, `ef25b0a`) was never recorded here. | correction |
| `DECISIONS/013-authoritative-narrative-state-document.md` | **Implementation note** on what "the protocol block is separated from the prose" now has to cover. | as-implemented note |
| `planning/README.md` | Status, milestone map and stop rule: the long-run evidence is complete. | index |
| `reports/M11-IMPLEMENTATION-REPORT.md` | **Revised** (`d198806`): M01-M04 on the complete run, §G.0 removed. | milestone report |
| `DEVELOPMENT.md` | Logging a GPU inference host during a long run, so a hardware fault can be tied to power or ruled out. | developer docs |

**The long-run evidence.** 101 accepted turns, three genuine restarts, every
scheduled history operation, zero failed post-turn passes, and recovery onto a
clean data directory 16 of 16. M04 passes on a positional precondition: the
planting turn was outside the history window, which is the acceptance text's own
"without entire transcript in prompt". The fact was recovered through
authoritative state, and it reached memory only as the narrator's restatement of
that state. The repository owner accepted state-based recovery on 2026-09-13.

**Two defects the memory bank had been hiding.** No long run had ever had it
switched on.

- **A turn locked out its own post-turn work.** It held SQLite's single write lock
  through the model call. Every memory, summary and status write during the reply
  timed out, and so did the record of the failure. A run reported `complete` with
  two memories and no summary.
- **The narrator's protocol was stored as story.** The model pasted the state
  section and unfenced proposals into its prose on up to 42 of 104 turns, and
  stored text is replayed as history.

**Requirement changes: zero.** The M04 precondition the harness measures was
corrected to the acceptance text's wording; the test itself is unchanged.

## v3.8 — Two gaps closed under M11's own rules, and the cost of a long turn (2026-09-10)

No milestone, no requirement change, and no acceptance claim. Three pieces of
work done while M01 was still outstanding: one hole in §15.2's guarantee, one
stale statement of fact, and the reason a long campaign cost the same per turn
however little had changed.

| Document | Change | Kind |
| --- | --- | --- |
| `TECHNICAL-DESIGN.md` | **§15.2 gains "the server that cannot be asked"** — discovery speaks Ollama's native API, nothing restricts the endpoint to Ollama, and on any other server the window goes unverified and the budget uncapped. `Settings.context_window_override` lets an operator state it; a verified window always wins, so a declaration can lower an unknown ceiling into existence and never raise a known one. | as-implemented record |
| `TECHNICAL-DESIGN.md` | **New §15.3** — the history window moves in blocks. What happens *at* §15.2's ceiling: a window that gave up its oldest action every turn changed the prompt near the front and cost a full re-read every turn. Records the two safety properties and that M11 §P.1's "no performance requirement" still stands. | as-implemented record |
| `planning/README.md` | **Corrected**: said M11's tree was "staged rather than committed" in two places. It was committed and signed on `m11-release-validation` (`fedb714`); `main` is still M10. | correction |
| `README.md`, `DEVELOPMENT.md` | The window override and how to set it; why a long campaign is not slow in proportion to its length, with the measurements. | developer docs |

**The window a server will not tell you.** §15.2 makes the application ask the
inference server what it will accept and cap itself to the answer. It asks over
Ollama's *native* API — and nothing restricts `endpoint_url` to Ollama. Against
vLLM, llama.cpp's own server, or anything else serving an OpenAI-compatible
`/v1`, `/api/ps` and `/api/show` are simply absent, discovery fails as designed,
and the budget stands uncapped at whatever is configured. §15.2's rule names
Ollama because Ollama is what M8 measured; the failure it forbids is not
Ollama's. The override closes that without weakening what `verified` claims:
`verified` still means the server answered, so `window_verified` in a turn's
provenance counts what M11's report says it counts, and a declared window is
identifiable as a declaration everywhere it appears.

**What a long turn was paying for.** 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 discarded that cache, so nearly the whole prompt
was reprocessed every turn regardless of how little had changed. The window now
snaps to a block and holds, stepping every few turns. Measured against the
reference deployment on real builder output, at an 8,192-token budget: **124.0s
per turn against 362.4s** with the floor disabled. The cost is history depth —
up to a block fewer actions right after a step — bounded by `TRIM_FRACTION` at a
quarter of the window, which is the dial between recent history and speed.

**Requirement changes: zero.** Nothing was retired, relaxed or reclassified.
§15.3 records explicitly that M11 §P.1 declines to set a performance requirement
and that this does not invent one: what changed is the cost of a turn, not what
a turn must contain.

## v3.7 — M11 implemented: v1 security, long-run and release validation (2026-09-07)

The release-validation milestone. Most of what it changed is evidence rather
than product; the product changes it did make were each forced by something the
validation found.

| Document | Change | Kind |
| --- | --- | --- |
| `TECHNICAL-DESIGN.md` | **New §15.2** — the inference window as a ceiling: how it is discovered, where it is enforced, and why there is no hard-coded 4,096. | as-implemented record |
| `DATA-MODEL.md` | **New §28B** — M11's one column (`narration_length`), and why the window ceiling, `duplicate_names` and `refused` are all deliberately *not* stored. | as-implemented record |
| `BROWSER-UX-SPEC.md` | **§8A gains an implementation note** — the position indicator that answers it, and the three properties that make it answer it. | as-implemented record |
| `SECURITY-THREAT-MODEL.md` | **New §42B** — the probe held to §73, the silent partial correction closed as a §69 gap, H09 recorded as not applicable with a test to keep it honest, and the measured contrast. | boundary + measurement notes |
| `V1-ACCEPTANCE-TESTS.md` | Results for the M11 release run against every REQUIRED test. | acceptance evidence |
| `BUILD-MILESTONES.md` | **M11 status block**, and the disposition of the four post-M8 playtest findings it owned. | milestone status |
| `README.md`, `DEVELOPMENT.md` | The context-window behaviour, `contextwindow.py` in the architecture map, and how to re-run the six release harnesses. | developer docs |
| `reports/M11-IMPLEMENTATION-REPORT.md` | New. The evidence package for independent release review. | milestone report |
| `reports/M10-IMPLEMENTATION-REPORT.md` | Moved to `archive/milestone-reports/`. | report rotation |

**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.

## v3.6 — M10 implemented: future media extension hooks only (2026-09-07)

M10 built the media seam and no media. The documentation change is mostly a
record of what was deliberately **not** built, because that is the part a later
reader will otherwise re-litigate.

| Document | Change | Kind |
| --- | --- | --- |
| `DATA-MODEL.md` | **New §28A**, the media extension points as implemented: one `visual_profiles` table, no scenes table, no job or asset tables, and why each. | as-implemented record |
| `TECHNICAL-DESIGN.md` | **New §15.1** under the Scene and Future Media Boundary: what the seam turned out to be, what the packet carries and excludes, the STT asymmetry, the endpoint policy. | as-implemented record |
| `MEDIA-EXTENSION-CONTRACT.md` | **New §90**, appended rather than woven in so the Phase 0B contract stays readable. Records the three places implementation answered an open question, and the sections left unbuilt. | as-implemented record |
| `BUILD-MILESTONES.md` | **M10 status block**: the finding that shaped the milestone, what shipped, and the migration defect its own tests caught. | milestone status |
| `V1-ACCEPTANCE-TESTS.md` | **K01-K04 results.** K01 passes and *was already passing*; K04 is reported on the acceptance text's deferred branch, as its own wording provides for. | acceptance evidence |
| `SECURITY-THREAT-MODEL.md` | **New §42A.** The trust boundary did not widen; in one place the implementation is deliberately **narrower** than §73 permits, which is still a discrepancy worth recording. | boundary note |
| `README.md`, `DEVELOPMENT.md` | The `media/` package in the architecture map, the backend test count (1,189), and the stricter rule a future media endpoint will meet. | developer docs |
| `reports/M10-IMPLEMENTATION-REPORT.md` | New. The implementer's account, written for a reviewer. | milestone report |

**The decision behind the whole milestone**: the scene snapshot the media
contract asks for **already existed** as `narrative_state["scene"]`, built by M5
and carrying lineage correctly since. Verified with a probe rather than taken
from an earlier report. So M10 added no scenes table, and derives the scene
packet on read.

**Two decisions recorded rather than assumed:**

- **The bundle format stays `ai-dnd-adventure-v3`.** M9's own semantic test —
  does omission create ambiguity about what an older file *could* have recorded?
  — says no: a campaign with no visual profiles is the ordinary case, so an
  absent key unambiguously means "none". Older v3 files still import.
- **M10 adds no migration.** A `CREATE INDEX` migration was written first and
  removed: `create_all` already builds the table and the index declared on its
  column, so the migration left an upgraded database holding an index a fresh
  install did not have. `LATEST_VERSION` stays 92.

**The four post-M8 playtest findings below remain M11's** and are untouched by
this entry.

## v3.5 — Post-M8 hands-on playtest findings recorded (2026-09-07)

**Documentation only. No application code changed, and M9's verified result is
untouched** — see the note at the end of this entry.

A real play session against **accepted, signed M8** (real browser, trusted-LAN
Ollama, `qwen2.5:3b-instruct-16k`, disposable database since destroyed) surfaced
four product-quality observations. **None is an M9 defect, none was caused by
M9, and none blocks M9 acceptance.** They are recorded so they cannot be lost
when the M9 report is archived.

| Document | Change | Kind |
| --- | --- | --- |
| `reports/M9-IMPLEMENTATION-REPORT.md` | **New §Y**, the full write-up with the verification behind each mechanism, plus a pointer from §W. Explicitly labelled as not-M9. | observation record |
| `BUILD-MILESTONES.md` | **New section before M10**, the durable copy owned by M11; a note bounding M10 out of it; the four items added to M11's scope list. | milestone sequencing |
| `V1-ACCEPTANCE-TESTS.md` | **New §P**, three items as **test-design tasks, explicitly not acceptance tests**, each naming what must be settled before it could become one. No existing test changed or weakened. | test design |
| `BROWSER-UX-SPEC.md` | **New §8A.** §8's *"The current endpoint should be clear"* was satisfied while a real reader was lost, so it could not hold the behaviour. States the orientation requirement; **prescribes no wording**. | requirement clarification |
| `TEST-CAMPAIGN-FIXTURE.md` | **New Appendix A** proposing a companion `Multi-Character Identity Test`. The established deterministic fixture is **unchanged** — altering it would invalidate earlier milestones' comparisons. | test design |

**What was verified rather than assumed**, since the playtest campaign no longer
exists and root causes largely cannot be proven:

- The browser title genuinely is `AI D&D` (`frontend/index.html`), and **no
  accepted document ever claimed otherwise** — so this is an uncovered gap, not
  documentation needing correction. Nothing was corrected and nothing was
  renamed: *Adventure Storyteller* is itself narrower than the genre-agnostic
  engine `SPECIFICATION.md` requires, and the naming decision is the owner's.
- The narration-length setting adds **one English sentence** and changes **no
  generation budget**, while the numeric hint derived from the global
  `max_output_tokens` is **identical for every setting** — measured at the
  default as *"must not exceed 506 words, and it should not stop short of about
  177."* Recorded as a mechanism to check first, **not** as the proven cause.
- The narrative state **permits two entities to share a display name and
  reports nothing** — `DUPLICATE_ENTITY` rejects a repeated key only. That is
  one of the identity finding's failure modes; it establishes nothing about what
  actually happened.

**M9 is unaffected.** No application file changed in this pass, so M9's final
verified result stands exactly as recorded: **1,102 backend passed / 14 skipped
/ 0 failed**, 145 frontend, 36/36 browser. The expensive M9 suites were
deliberately **not** re-run, because only Markdown changed.

## v3.4 — M9 Implementation (2026-09-07)

M9 — Export, Backup, Recovery, and Migration Hardening — is implemented on
`m9-recovery` from the signed M8 commit `1ce9972`. This revision records what the
implementation settled. It is **not** an acceptance: the milestone report is
written for a reviewer and the tree is staged for the repository owner's signed
commit.

**Requirement corrections:** none. M9 altered no product requirement.
`SPECIFICATION.md` and `SECURITY-THREAT-MODEL.md` are unchanged — §16 already
required the export to preserve the exact active position, §6.1 already required
an exact prompt/context snapshot per turn, and M9 implements both rather than
redefining either.

| Document | Change | Kind |
| --- | --- | --- |
| `DATA-MODEL.md` §29 | The v3 format, the three-category rule (chosen / evidence / rebuildable), what each version can be trusted to say, the encoding of the snapshots, and the two pointers the import translates. | implementation fact |
| `TECHNICAL-DESIGN.md` §9.3 | Why the version was bumped when §9.1 and §9.2 each correctly declined one; the third data category; the two-phase transaction and the warning path for a failed derived rebuild. | implementation fact |
| `TECHNICAL-DESIGN.md` §9.4 | **New.** The SQLite backup: the online backup API rather than a file copy, the verify-then-rename order, and why there is no restore endpoint. | implementation fact |
| `IMPORTED-KNOWLEDGE-DESIGN.md` §73 | **New subsection.** Story Cards settled as compatibility-only legacy data and removed from the narrator's prompt, with the evidence that they were the "alternate untracked path" §73 already forbade. | newly settled design decision |
| `V1-ACCEPTANCE-TESTS.md` I01-I07, L02-L04 | Results recorded. I05's M7-era limit is marked closed with the original paragraph kept, because the M9 decision is only legible against it. L04 records the defect running it found. | implementation fact |
| `BUILD-MILESTONES.md` M9 | Marked complete, with what it delivered, the three defects it found, the story-card decision, and the debt carried forward. | implementation fact |
| `README.md`, `VERSION.md` | Status. | implementation fact |
| `DEVELOPMENT.md` | **New section**: the two recovery tools and when each applies, taking a backup, and the stop-move-start restore procedure. Plus a note that an imported long campaign meets a small context ceiling on its first turn rather than gradually. | implementation fact |

**The four M8 handoff questions, answered**

| | Answer |
| --- | --- |
| **A. Complete campaign portability** | Every family travels and is measured family by family, before and after, by a tool a reviewer can rerun. |
| **B. Historical prompt provenance** | **It belongs in the bundle, and it is in it.** An old turn in a restored campaign shows what it was actually given, after the source has been deleted and the canon edited. |
| **C. Legacy story cards** | Compatibility-only. Carried in both directions; removed from the narrator's prompt; still the summariser's character roster. |
| **D. Context-window portability** | The campaign travels; the machine's model configuration does not. Importing changes no setting of the destination's, and a campaign imports whether or not any model is installed. The window itself remains M11's. |

**What the implementation found rather than assumed**

Three defects, all found by running the milestone's own tests rather than by
reading: an FTS index leak that made an ordinary import fail in an unrelated
campaign and that Reindex could not repair; an imported node with no state
snapshot being stamped with the campaign's *head* state; and a snapshot pointer
that was not being translated because the code mutated a dict in place. The
first two predate M9.

One measurement changed a plan, and then corrected the conclusion drawn from it.
Carrying per-turn prompts looked like it would halve the length of campaign that
can be restored. Measured, and after compressing them inside the file, everything
M9 added costs **12%** of reachable campaign length — the import ceiling moves
from about 318 turns to about 279, against a 100-turn certification target. The
dominant cost is not M9's at all: the **per-position narrative state document is
74% of a bundle**, and v2 already carried it.

## v3.3 — M8 Closeout (2026-09-06)

M8 is **complete and accepted**. The independent review returned
`M8 IMPLEMENTATION: PASS` subject to evidence and documentation cleanup; this
revision is that cleanup. No product requirement changed and no application code
changed in it.

**What M8 leaves the package with**

- **The browser is now the intended v1 storyteller surface**, not an adapted
  AI-DnD one. One entry point, one story screen, one natural-language field;
  State, Knowledge, Context, Save Points and campaign Settings one layer deeper
  behind panels that start closed. Branch, fork, node, head and depth appear
  nowhere a reader can see them — audited in source and in the live DOM, 0 hits.
- **Automated frontend testing exists for the first time** — 132 tests across 10
  files. The project had none before M8.
- **Hidden narrator information is withheld at the surface that can actually
  expose it** — advanced context inspection — rather than through a fictitious
  separate hidden-state subsystem. Withheld text is absent from the DOM, not
  collapsed inside it.
- **Final acceptance evidence:** 950 backend passed / 14 skipped / 0 failed; 132
  frontend passed; lint, production build and Docker build clean; **157 browser
  checks across six suites, zero failures**, on one frozen build; no schema
  change, proved against an M7-built database.
- **M9 — Export, Backup, Recovery, and Migration Hardening — is next.** Its four
  handoff questions are in the M8 report's §U.

**What the closeout settled**

- **The build-evidence contradiction.** The M8 report named two different
  frontend bundles as the artifact behind its acceptance evidence. The saved run
  logs settle it: `index-Ii-lARp9.js`, built 18:53:02 from the staged tree, is
  the one **final frozen** artifact behind all 157 browser checks.
  `index-C6E5Uvtu.js` is **superseded** — it predates finding 7's fix and its
  acceptance suite ended 54/55 on exactly that defect. The report's §P now sets
  the two side by side, and §B, §Q and §S agree with it.
- **Finding 14 — resolved, operationally, with no application change.** Ollama's
  OpenAI-compatible endpoint ignores `num_ctx` and reloads the model at its own
  default, so the window cannot be set per request from where this application
  stands. A **derived model** created over `/api/create` carries the parameter,
  is honoured through the application's own OpenAI-compatible path, and appears
  in `/v1/models` — so the existing Settings model picker finds it with no code
  change. Measured end to end. It is now an operational note in
  `DEVELOPMENT.md`, not an unresolved M11 blocker.
- **`BROWSER-UX-SPEC.md` §38 — ratified.** The change from *"Show Hidden Story
  State"* to the requirement on **hidden narrator information / spoilers** is
  accepted as a **requirement clarification aligned with the implemented
  architecture**, not a weakening: ordinary Story and State surfaces expose no
  narrator-only information; the advanced Context and Knowledge surfaces that
  could withhold it by default; revealing it takes an explicit, warned action;
  withheld material is **absent from the DOM**, not merely collapsed; and no
  duplicate hidden-state subsystem is required to satisfy obsolete UI wording.
  Verified by the sentinel suite, 21/21.

**Documents changed**

- `reports/M8-IMPLEMENTATION-REPORT.md` — §A, §B, §D, §P, §Q, §S (findings 13
  and 14), §T, §U and §V. §U gains the **M9 handoff**: complete campaign
  portability, historical prompt/context provenance in the bundle, legacy story
  cards, and context-window portability. Verification figures unchanged.
- `BROWSER-UX-SPEC.md` §38 — one requirement added: withheld material must be
  **absent from the rendered DOM**, not merely visually collapsed. A closed
  `<details>` is still findable by browser search and by the accessibility tree,
  which is how finding 3 leaked.
- `PROJECT-SOURCES.md`, `V1-ACCEPTANCE-TESTS.md` — three pointers still aimed at
  `reports/M7-IMPLEMENTATION-REPORT.md`, which M8's rotation moved to the
  archive.
- `BUILD-MILESTONES.md` — M8 marked **COMPLETE / ACCEPTED**, M9 marked next and
  not started, finding 14's carried-forward entry reworded as resolved.
- `README.md` (planning) — M8 complete and accepted; next is M9.
- `VERSION.md` — this entry.
- `DEVELOPMENT.md` — the derived-model procedure (carried from the finding-14
  investigation).

**Status discipline.** M8 is implemented, verified, reviewed and accepted. It is
**not committed**: the tree is staged for the repository owner's signature. M9
has not been started.

## v3.2 — M8 Final Verification Pass (2026-09-06)

The corrective, verification and reporting pass over M8. At the time of this
revision M8 was **implemented and verified, not accepted**; v3.3 records the
review outcome and the acceptance.

**Documents changed in this pass**

- `BROWSER-UX-SPEC.md` §38 — **requirement clarification.** Rewritten from
  "Hidden Narrator State" with a `Show Hidden Story State` toggle to
  "Hidden Narrator Information / Spoilers". The protection required is
  unchanged and, if anything, stated more strictly; what changed is that it
  no longer names a state subsystem that does not exist, and it now forbids
  inventing one. §100's checklist entry follows it.
- `TECHNICAL-DESIGN.md` — **implementation fact.** Campaign canon is
  configuration; its provenance is the per-turn context snapshot, measured
  rather than assumed.
- `V1-ACCEPTANCE-TESTS.md`, `BUILD-MILESTONES.md`, `README.md`,
  `DEVELOPMENT.md` — implementation facts and final counts.

**No product requirement was weakened.** The §38 change is the only one that
touches a requirement's wording, and it tightens it.

---

## v3.1 — M8 Implementation (2026-09-06)

M8 turned the adapted AI-DnD interface into the interactive-story workspace
`BROWSER-UX-SPEC.md` describes. Not yet accepted — the report is written for an
independent reviewer.

**Documents changed**

- `BROWSER-UX-SPEC.md` — four "As implemented in M8" notes (§12 one input, §31
  the state panel and why there is no hidden-state toggle there, §55 the context
  inspector's default view, §57 click-through and the narrator-only guard). No
  requirement was altered.
- `TECHNICAL-DESIGN.md` — new §13.4, recording that the browser stayed a
  presentation layer, the failure taxonomy, and why markup is never produced
  from input.
- `BUILD-MILESTONES.md` — M8's outcome and the debt it carries forward.
- `V1-ACCEPTANCE-TESTS.md` — B01-B04 and D01-D14 recorded as browser evidence.
- `README.md`, `DEVELOPMENT.md` — one input rather than four modes, the context
  inspector, the component test suite, and the removal of "no frontend tests"
  from the inherited-debt list.

**What M8 established that the plan did not already say**

- The narrative state has **no hidden dimension**, so §38's `Show Hidden Story
  State` has nothing to reveal there. A campaign's secrets live in narrator-only
  knowledge sources, and the only ordinary screen that can surface one is the
  context inspector — which is where the guard was built.
- `campaign_canon` had no API. It is the highest authority in a campaign, read
  by both the prompt builder and the state validator since M5, and until M8 a
  fixture had to write it with SQL.
- AI Dungeon's `> You {text}` player-input convention is incompatible with one
  natural-language field: it produced `> You I enter the tavern.`, which a small
  model then imitates. Corrected for first-person input.

---

## v3.0 — M7 Closeout (2026-09-06)

M7 is complete. Two items the corrective pass had left open are resolved.

**The embedding-model calibration boundary.** `SEMANTIC_FLOOR = 0.58` was
measured against `nomic-embed-text`, and the corrective pass documented only the
safe half of that: a model scoring everything lower degrades to lexical-only. A
model scoring unrelated material *higher* would have recreated M7-F1 on a build
whose tests all pass. Semantic admission is now **per model**: an uncalibrated
model does not inherit the threshold, semantic retrieval is skipped for it with
the reason reported, and the library degrades to lexical-only. Recorded in
`TECHNICAL-DESIGN.md` §13.3 and `IMPORTED-KNOWLEDGE-DESIGN.md` §76.

**The ambiguous `export/import 53/54`.** The 54th case was a false positive in
the independent review's own harness — its "no filesystem path" assertion was a
substring test that fired on `text/markdown`, a MIME type. Replaced with three
precise checks; the suite is **56/56** and no product behaviour was involved.

**What closeout changed in the active documents:**

- `TECHNICAL-DESIGN.md` §13.3 — **new.** A similarity threshold is a property of
  the model, the two ways a different model breaks it are not symmetric, and the
  product refuses to apply a threshold to a model it has not measured.
- `IMPORTED-KNOWLEDGE-DESIGN.md` §76 — the same, in the design's own terms:
  §25's local-Ollama embedding stands; what is added is that a *threshold* must
  be measured before it is trusted.
- `BUILD-MILESTONES.md` M7 — marked COMPLETE, with the capabilities later
  milestones inherit and the debt carried forward, including that calibrating
  further embedding models is a measurement rather than a guess.
- `V1-ACCEPTANCE-TESTS.md` — the M7 results promoted from implementation-pass
  evidence to reviewed results.

## v2.9 — M7 Independent Review and Corrective Pass (2026-09-06)

The review returned *PASS WITH CORRECTIVE WORK REQUIRED*. It closed the five
acceptance conditions the implementation had flagged as unmeasured — C05, G06,
G07, G10 and hidden Canon, all exercised against a real narrator and all
passing — and found two blocking defects, both now corrected.

**M7-F1 — imported knowledge was injected regardless of relevance.** Relevance
was decided by a floor expressed as a share of the best candidate, which the
best clears by construction. A query about tide tables and container tonnage
retrieved all five sources of a fantasy campaign, narrator-only hidden Canon
among them. Corrected by separating relevance **admission** from **ranking**.

**M7-F2 — the retrieval suite could not detect it.** Its stub scored unrelated
text an order of magnitude lower than the real model, so the broken gate passed.
Corrected with a stub that has the real model's similarity floor, plus a test
that fails if the floor is removed and one that shows the superseded rule still
being fooled. The new suite fails 13/18 against the pre-corrective code.

**What the corrective pass forced into the active documents:**

- `TECHNICAL-DESIGN.md` §13.2 — **new.** Relevance admission is a separate stage
  from ranking, and the general rule behind it: a relevance decision must rest on
  a signal meaningful on its own, because normalization answers "which of these
  is best" and can never answer "is any of these any good". A pipeline that ranks
  first and cuts second has no way to return nothing.
- `TECHNICAL-DESIGN.md` §13.1 — the pipeline diagram gains the admission stage.
- `IMPORTED-KNOWLEDGE-DESIGN.md` §76 — retrieval corrected: admission before
  authority, and the plain statement that **retrieval may return nothing**,
  which is what §30 means when every source is irrelevant.
- `BUILD-MILESTONES.md` M7 § Status — both findings, their corrections, and the
  model-specific calibration recorded as carried debt.

Three non-blocking findings were folded in: a relevance constant that could
never fire was removed rather than re-tuned; the acceptance tests moved to the
standard `TEST-CAMPAIGN-FIXTURE.md` §12 files so G07's trap is finally
exercised; and Unicode format characters are stripped from displayed filenames.
A pre-existing M5 narrator-protocol issue was recorded and deliberately left
with M5.

## v2.8 — M7 Implementation Pass (2026-09-06)

**Not a closeout.** M7 is implemented, not accepted, and this revision records
what the implementation pass built and measured so that an independent review
has something to verify against. No milestone report was written: the
convention this package follows puts the report in `reports/` and has the
*reviewer* write it, treating the build summary as claims to check.

**M7 — First-Class Imported Knowledge Library.** A campaign can import local
`.txt` and `.md` files as Canon, Reference or Inspiration; retrieval is hybrid
(SQLite FTS5 plus local Ollama embeddings), reranked by relevance × class,
bounded by its own token budget, framed in the prompt as untrusted data with the
authority order stated in words, and fully traceable in the Insights panel. It is
a separate subsystem: AI-DnD's Story Cards were not promoted into it and are
untouched.

**What implementation forced into the active documents:**

- `TECHNICAL-DESIGN.md` §13.1 — **new.** The implemented pipeline, and four
  decisions that each replaced an obvious wrong one: the class multiplies
  relevance rather than adding to it; both retrieval scores are normalized per
  query against the best of their own path; the relevance floor is therefore
  relative rather than absolute; and lexical retrieval is a production path
  rather than a fallback.
- `DATA-MODEL.md` §24A — **new.** The three tables and the FTS5 virtual table,
  and the line between what the reader gave the campaign and what the machine
  derived from it. Only a source's content and its classification are not
  derivable.
- `DATA-MODEL.md` §25 — the retrieval record is **not** a table. It lives in the
  turn's own context snapshot and carries the *rendered text*, because a table of
  foreign keys would turn every historical turn's evidence into dangling
  references the moment a source were deleted.
- `DATA-MODEL.md` §29 — what the bundle carries for imported knowledge, and why
  passages, index rows and vectors are rebuilt rather than exported.
- `CONTEXT-AND-MEMORY.md` §29, §41-42, §46 — the knowledge budget as implemented
  (a protected cap for always-included Canon, a share of the rest filled in
  authority order), always-include as a Canon-only mechanism, and hidden Canon as
  prompt discipline rather than as filtering.
- `IMPORTED-KNOWLEDGE-DESIGN.md` §76 — **new.** Where this document offered
  options, which was chosen and why; and, named rather than left to be
  discovered, the six things it contemplates that M7 does **not** implement —
  entity linking, tags, manual priority, scene pinning, Canon-versus-Canon
  conflict detection, and source versioning.
- `V1-ACCEPTANCE-TESTS.md` — results for G01-G10, C05, F05, F06, I05 and
  H06-H09, marked as implementation-pass evidence rather than review findings.
  F05 and F06 move from *PARTIAL / PASS for story memory* to complete. H09 is
  recorded NOT APPLICABLE with a test that fails if an archive extractor is ever
  added to this surface. **C05 is recorded as a pass on the assembled prompt
  with the gap stated**: no real narrator generation was run against it.
- `BUILD-MILESTONES.md` M7 § Status — **new.** What was built beyond the scope
  list, and the debt carried forward, deliberately.

**One runtime dependency was added**: `python-multipart`, Starlette's multipart
parser. It is what makes the upload surface possible, and the upload surface is
why no endpoint in the knowledge API accepts a filesystem path.

## v2.7 — M5 and M6 Closeout (2026-09-06)

Two milestones, and one lesson they share: an independent review found a real
defect in each after the implementation reported success, and in both cases the
defect was invisible to the tests the implementation had written for itself.

**M5 — Genre-Neutral Authoritative Narrative State.** Accepted 2026-09-04. Its
review returned *PASS WITH CORRECTIVE WORK REQUIRED*: editing a narrator turn
rewound the campaign's live state while the head stayed at the tip, breaking the
`transcript position == head == authoritative state` invariant. The corrective
pass rebuilt narrator editing on the §§14-15 fork semantics. Recorded here late:
M5's closeout did not add a package revision entry, and this one covers it.

**M6 — Branch-Safe Context, Summaries, and Long-Term Story Memory.** Accepted
2026-09-06. Sequence:

1. **Implementation.** Summaries moved onto lineage-anchored rows; memory
   authority, provenance, an output reserve, and observable derived-work
   failure were added. Reported as passing, including E03.
2. **Independent review — E03 still failed.** Summary *rows* were anchored, but
   generation was seeded from `adventures.story_summary`, a campaign-global
   column with no lineage. After a divergence the summariser was handed the
   abandoned line's prose and asked to update it, so the new summary carried
   abandoned content inside a correctly anchored row. The review also found F02
   passing by a single retrieval slot, two test defects, and a misleading
   derived-work status.
3. **Corrective pass.** Generation is seeded from `summaries.current`;
   redundancy suppression was added before the retrieval cut; the test fixture
   no longer makes real network calls; the browser suite gained a scenario that
   regenerates a summary after divergence.

**What the planning package learned from M6, recorded in the active documents:**

- `CONTEXT-AND-MEMORY.md` §11 — lineage safety has two halves. Anchoring the
  output row is not enough; the *input* to the summarizer must be scoped by the
  same rule.
- `V1-ACCEPTANCE-TESTS.md` E03 — a valid test must regenerate a summary after
  diverging. Checking only that the old row went ineligible passes while the
  defect is live.
- `CONTEXT-AND-MEMORY.md` §20/§22 — what M6 implements (redundancy suppression
  between memories) is now distinguished from what it does not (importance,
  entity, recency and thread ranking; cross-layer duplication).

## v2.6 — M4 Closeout (2026-09-03)

M4 is **accepted**. Its review returned *PASS WITH CORRECTIVE WORK REQUIRED*; the
corrective work is done, and the browser condition that M3 and M4 both carried is
closed.

**The three review findings, fixed:**

- **B-1 — the Save Point list was an N+1.** It resolved each Save Point with its
  own query and loaded whole `Action` rows, narration included, to answer "does a
  row exist here". It is now one bulk two-column coordinate query plus one
  lineage computation: **53 SELECTs for 25 Save Points became 5**, and the count
  no longer grows with the list. Guarded by three tests, including one proving
  the coordinate is matched as a *pair* — an `IN`-list version would report a
  Save Point resolved because another branch has a live row at the same depth.
- **B-2 — deleting a branch silently deleted its Save Points.** Fixed as a
  **behaviour** defect rather than a missing warning, because
  `STORY-BRANCH-SEMANTICS.md` §19 says a named checkpoint remains until
  explicitly deleted and §28 already required future cleanup to retain
  checkpoint-referenced paths. **A branch a Save Point names can no longer be
  deleted.** The request is refused with the offending Save Points named; the
  user deletes them explicitly, which deletes no story, and the branch then
  goes. Both delete controls disable and explain. Recorded as a new
  **§19.1**.
- **B-3 — the D11/L03 automation never left one process.** A new module spawns
  real server processes, kills the first, and reads the campaign back with the
  second.

**Also fixed (review §S C-5):** creating a Save Point now takes the campaign's
turn lock, so "save where I am" cannot read a head a turn in flight is about to
move. Rename and Delete deliberately do not take it, and a test pins that
decision.

**Real-browser verification — the first in this project.** A Firefox 154.0.1
driven through geckodriver over the W3C WebDriver protocol exercised the rendered
DOM for **both** milestones: **44/44 checks passed**, no console errors. It
covered M3's Undo/Redo enable states, transcript movement, Retry and the take
pager, and divergence retiring Redo; and M4's whole Save Point lifecycle
including both confirmations and the new branch-delete warning. **The outstanding
M3 browser condition is therefore closed as well.** No dependency was added to
the repository: the WebDriver client for the run was written against stdlib HTTP.

**Also corrected, found while fixing B-2:** `models.py`, `TECHNICAL-DESIGN.md`
§8.8 and `DATA-MODEL.md` §8 all described the cascade as the durability rule.
They now describe the refusal, and record that `checkpoints.branch_id`'s cascade
survives as referential integrity that the application no longer reaches.

**Documents corrected by this closeout:**

- `V1-ACCEPTANCE-TESTS.md` records results for **D11-D14, I04, L03** and the
  E-series, and states that the browser-level condition is satisfied. **No pass
  condition was weakened** — and D11/L03 now note that the automation crosses a
  genuine OS process boundary, which is the standard later milestones should
  meet.
- `DATA-MODEL.md` §8 records the coordinate as implemented, with the retry
  measurement that settles coordinate-versus-turn-id, and three decisions that
  were previously implicit: names are not unique, several Save Points may name
  one position, and the list is newest-created first.
- `STORY-BRANCH-SEMANTICS.md` gains **§19.1** — a checkpoint protects the
  history it names. This is the only behavioural specification change in the
  closeout, and it strengthens §19 rather than weakening anything.
- `BROWSER-UX-SPEC.md` §25 rules for the implemented vocabulary: **Moment N**,
  not *Turn N*, because the branch panel and tree overlay already count in
  moments. Vocabulary only; no behaviour changes.
- `BUILD-MILESTONES.md` marks **M4 COMPLETE**, records the fixes and the browser
  result, and warns M5 that the instrumentation to move is now **55 tests**.
- `README.md` records M1-M4 accepted and M5 as next to brief.
- `PROJECT-SOURCES.md` and `project-sources.txt` point at the current report;
  `project-sources.txt` still named the archived M3 report and was corrected.

**Report rotation** happened in the reporting pass that preceded this closeout:
`M3-IMPLEMENTATION-REPORT.md` moved to `archive/milestone-reports/` as a pure
rename, and `reports/` now holds M4's report, whose **§W** is this closeout's
evidence record.

**No new ADR.** ADR 012 already decides the architecture, and the corrective work
forced no new architectural decision. `SPECIFICATION.md`,
`STORY-BRANCH-SEMANTICS.md`, `SECURITY-THREAT-MODEL.md`, `CONTEXT-AND-MEMORY.md`,
`IMPORTED-KNOWLEDGE-DESIGN.md` and ADRs 003, 005 and 012 are unchanged.

**M5 readiness:** ready. Save Points store no state and no checkpoint code reads
any, so M5 can change what a snapshot contains without touching what a Save Point
is — provided it keeps state recoverable at a position without replay
(`TECHNICAL-DESIGN.md` §10.4).

## v2.5 — M4 Implementation (2026-09-03)

M4 added durable named Save Points. This revision records only what the
implementation established as fact; **no product requirement changed**, and the
milestone is **not** marked accepted — its review has not been written.

- `TECHNICAL-DESIGN.md` gains **§8.8** and **§9.2**: the Save Point as a name
  plus a coordinate holding no story, restore as head movement with a bounds
  check, the rule that the branch half of the head moves only when the
  coordinate is off the path being read, restore never forking, and the bundle
  carrying Save Points independently of the head.
- `DATA-MODEL.md` **§8** records the pointer as implemented — `(branch, depth)`
  rather than a turn id, with the reason: 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 superseded take. **§29** records the checkpoints in the export.
- `BUILD-MILESTONES.md` **M4** gains a status block: what shipped, the one
  architectural decision the milestone had to make and why it needed no new ADR,
  the test count, and the outstanding browser condition.
- `README.md` describes Save Points as a user-facing capability.

**No ADR was created.** ADR 012 already decides the architecture M4 needed —
restore reuses active-head movement — and a table is not a decision. The one
question ADR 012 does not answer, whether restore moves the branch half of the
head, is that same mechanism applied to a coordinate ADR 012 already defines;
`TECHNICAL-DESIGN.md` §8.8 records the answer rather than a new ADR asserting it.

`SPECIFICATION.md`, `SECURITY-THREAT-MODEL.md`, `STORY-BRANCH-SEMANTICS.md` and
`V1-ACCEPTANCE-TESTS.md` are unchanged. M4 altered no product requirement, added
no outbound path, and implemented the checkpoint semantics
`STORY-BRANCH-SEMANTICS.md` §18-25 already specified rather than amending them.

**The browser smoke test remains unperformed, now for both M3 and M4.** No
session has had a usable browser. See `BUILD-MILESTONES.md` M3 and M4.

## v2.4 — Documentation Consolidation (2026-09-03)

No product requirement, architecture decision or milestone status changed in
this revision. It reorganises the documentation so that a new coding agent can
tell authoritative material from evidence at a glance.

- `planning/archive/` is created and is **non-authoritative by declaration**
  (`archive/README.md`). It holds `phase0/` — the research that chose AI-DnD —
  `milestone-reports/` — the completed M1 and M2 reports — and `decisions/`,
  which now holds ADR **008**, the Phase-0-before-build process gate that Phase 0
  satisfied. ADR numbering continues from 012; 008 is not reused.
- `planning/reports/` now holds **only the current milestone's report**,
  `M3-IMPLEMENTATION-REPORT.md`, because M4 planning has to consult it. It moves
  to the archive when M4's report replaces it.
- The Phase 0B execution prompts and handoff/status/summary documents
  (`CODEX-HANDOFF-NOTE.md`, `PHASE-0B-CODEX-BRIEF.md`,
  `PHASE-0B-CODEX-HANDOFF.md`, `PLANNING-UPDATE-SUMMARY.md`) and the Phase 0A
  discovery and triage reports were **deleted**: intermediate working documents
  whose conclusions all reached the two recommendation reports, and which remain
  in Git history.
- Upstream AI-DnD's inherited `plan/` build log and `docs/` project site
  (guides, generated HTML, screenshots) were **deleted**. They documented a
  hosted, scripted, multi-user product with accounts — every screenshot showed a
  Scripts tab and a Sign up button — which M2 removed. Both trees remain in Git
  history and in upstream.
- `README.md`, `DEVELOPMENT.md` and `PROVENANCE.md` are corrected where they
  pointed at the removed trees or described removed capability as present.
  `DEVELOPMENT.md`'s "things M1 did not touch" section had gone stale at M2 and
  now says what is actually still inherited.
- `planning/README.md` is rewritten as **the documentation index**: current
  milestone, the three-way active/ADR/archive split, the authority order,
  reading order, where reports live, and what comes next. The milestone
  correction tables are preserved unchanged.
- New: `planning/PROJECT-SOURCES.md` and `planning/project-sources.txt`, the
  manifest of files to upload as ChatGPT Project Sources.

## v2.3 — Post-M3 Closeout (2026-09-03)

M3 replaced destructive Undo with a stored active head. Its review is
`archive/milestone-reports/M3-IMPLEMENTATION-REPORT.md`, which is also M3's primary evidence
record — no separate baseline report was produced — and whose §W records this
closeout.

In summary:

- the architecture is recorded as **ADR 012 — Active-Head Non-Destructive
  History**: the head is stored rather than derived, every read of the story is
  capped at it in one place, one mechanism moves it, state comes from the node
  rather than from a replay, the first write below a moved-back head is the
  divergence, and Redo is decided by the lineage rather than by a flag. ADR 005
  is unchanged: it states the product requirement, and ADR 012 states the
  architecture chosen to implement it,
- two history semantics are **ratified** in `STORY-BRANCH-SEMANTICS.md`: Undo
  crosses fork points to the campaign opening (§5), and the system refuses to
  switch which take is live while a later story is off screen (§10),
- a **new §14A** records the interim in-place-editing rule — refuse when story
  descends from the turn and is not on screen — and states explicitly that
  §14-15's full narrator-edit requirement stands and is completed in M5,
- `TECHNICAL-DESIGN.md` gains **§8.7** and **§9.1** recording the implemented
  model and bundle behaviour as fact, and a constraint on §10.4: the snapshot
  half of the hybrid state model is a requirement, because head movement must
  not become proportional to campaign length,
- `DATA-MODEL.md` records the head as campaign-stored, the branch disposition as
  implemented and deliberately advisory, and the export as carrying a chosen
  position rather than a derived one,
- `BUILD-MILESTONES.md` marks **M3 complete**, states the one outstanding
  condition (the browser smoke test), tells **M4** to reuse M3's head movement
  rather than build a second restore path, and gives **M5** three constraints,
- `V1-ACCEPTANCE-TESTS.md` records D03's full pass, states **D10's milestone
  ownership without weakening any pass condition**, adds I07's pre-M3 bundle
  clause, and resolves the apparent L01/A05 conflict,
- `README.md` is corrected to describe the current local-only single-user
  application rather than the upstream hosted one.

`SPECIFICATION.md` and `SECURITY-THREAT-MODEL.md` are unchanged: M3 altered no
product requirement and touched no path in the threat model.

## v2.2 — Post-M2 Closeout (2026-09-03)

M2 removed the hosted, cloud, account and scripting surface and added the
inference endpoint policy. Its review recommended six planning changes and
reported rather than applied them; all six are applied in this revision, listed
in `README.md` § *Post-M2 corrections applied*, with the evidence in
`archive/milestone-reports/M2-BASELINE-REPORT.md` and `archive/milestone-reports/M2-IMPLEMENTATION-REPORT.md`.

In summary:

- the **inference endpoint policy is recorded as implemented** — an address
  allowlist of explicit local-network CIDRs, every resolved address checked,
  enforced when settings are saved and again before every outbound request, with
  TLS verification never traded against it (new **ADR 011**,
  `SECURITY-THREAT-MODEL.md` §10A),
- its two **residual limits are stated rather than mitigated**: a hostile host
  already on the trusted LAN, and the DNS-rebinding interval between the
  policy's resolution and the client's connection,
- `TECHNICAL-DESIGN.md` §5.1 items 3 and 4 are **resolved**, and a new §5.2
  records the M1/M2 production architecture as fact,
- a **wiring rule** is added (§18.1): removing a setting requires testing a real
  consumer path, and adding one requires proving it reaches its component — M2
  shipped two defects behind a 604-test green suite because the tests at that
  boundary were mocks,
- `BUILD-MILESTONES.md` records **M2 complete**, warns M5 that eight rollback
  tests use the world-state engine as instrumentation rather than as
  architecture, and requires M6 to make background memory failure observable,
- the security acceptance contract is strengthened: **H10** now names the
  wildcard-origin and `/api` 404 conditions, and new **H12** covers inference
  endpoint enforcement including the database-edited-behind-the-API case.

`SPECIFICATION.md` is unchanged: M2 altered no product requirement. Nothing in
the architecture selected in v2 was reversed.

## v2.1 — Post-M1 Corrections (2026-09-02)

M1 implementation evidence contradicted or under-specified parts of v2. The
corrections are recorded in the documents themselves and listed in
`README.md` § *Post-M1 corrections applied*; the evidence behind them is in
`archive/milestone-reports/M1-BASELINE-REPORT.md` and `archive/milestone-reports/M1-IMPLEMENTATION-REPORT.md`.

In summary:

- a trusted-LAN Ollama may be **HTTPS with a privately issued certificate**;
  clients verify against the operating system's CA store, with full certificate
  and hostname verification and no bypass option (ADR 002,
  `TECHNICAL-DESIGN.md` §5, A06),
- offline claims require a **fresh cache and no route out** to be evidence at
  all, and vendored runtime artifacts should be integrity-verifiable
  (ADR 004),
- A05's invariant is about **accepted** history; the user's submitted text is
  deliberately retained on a failed turn,
- A06 requires a **real second machine and an HTTPS endpoint**; a plain-HTTP
  LAN test is no longer sufficient evidence,
- the standard test environment records **CPU/GPU/RAM**, because cold model
  load on a CPU-only host exceeded the inherited 120 s client timeout,
- `BUILD-MILESTONES.md` records M1 as complete and reframes M2's endpoint work
  as **narrowing** an existing capability rather than inventing it,
- `SECURITY-THREAT-MODEL.md` §53 distinguishes **inbound** TLS (still deferred)
  from **outbound** certificate verification (required, done in M1).

Nothing in the architecture selected in v2 was reversed.

## v2 — Post Phase 0B Revision (2026-09-01)

This v2 package supersedes the earlier planning package produced before the final Phase 0B review and the trusted-LAN Ollama deployment clarification.

Key v2 changes include:

- AI-DnD selected as the production base at the pinned Phase 0B commit.
- Non-destructive head-cursor Undo/Redo design selected.
- Explicit typed/absolute narrative-state events selected for production state handling.
- The authoritative narrative-state document — its shape, its authority/provenance fields, and the
  event/document/snapshot split — recorded in ADR 013 after M5 implemented it.
- Imported knowledge separated from AI-DnD Story Cards.
- Trusted-LAN Ollama inference supported in v1 while the storyteller UI/API remains loopback-bound by default.
- Offline first-use dependencies and runtime remote assets identified as M1 hardening work.
- Production implementation divided into milestones M1-M11.

Historical Phase 0 prompts/reports are retained as evidence and should not be treated as current implementation instructions unless a current milestone prompt explicitly refers to them.
