Stop refusing sign-in over a scheme other than the public URL's

The auth routes no longer return 400 when the resolved request scheme
differs from MEALQUEST_PUBLIC_URL's. If Docker's published-port path
presents its bridge gateway instead of Traefik as the direct peer, the
forwarded headers are rightly ignored, but sign-in must still work: the
OIDC redirect URI and the Secure cookies are fixed by MEALQUEST_PUBLIC_URL,
not by the request. internal/auth is back to its state before the
trusted-proxy change; client IP and scheme resolution stays in the router.

Add TestLoginThroughRouter: it wires the real auth flow and session
manager through server.NewRouter, trusting Traefik only, and checks that
a login from Traefik and from an untrusted peer both redirect with the
redirect URI from MEALQUEST_PUBLIC_URL and set a Secure login cookie.

-## Stack
+## Quick start
 
-- **Backend:** Go 1.25 (`CGO_ENABLED=0`, one static binary), chi router,
-  SQLite through `modernc.org/sqlite` with sqlc queries and embedded
-  migrations, Authentik OIDC, `log/slog`. AI calls go to an
-  OpenAI-compatible, Anthropic or Ollama endpoint over plain HTTP; recipes
-  come from SearXNG or Brave search and the recipe page's schema.org data.
-  Google Calendar, Google Chat and Web Push are the integrations.
-- **Frontend:** React 19, TypeScript, Vite, React Router 7, TanStack Query 5,
-  `vite-plugin-pwa`, CSS Modules over the design tokens; tests with Vitest,
-  Testing Library and jsdom.
-- **Deployment:** a Docker Compose stack (the service, Litestream
-  replication to the NAS, a SearXNG sidecar) behind Traefik, with systemd
-  units for the firewall, nightly media backup and the automated deploy of
-  `main`.
+Requirements: Go 1.25 and Node.js `^22.22.2 || ^24.15.0 || >=26.0.0` — that
+is, 22.22.2 or later on the 22 line, 24.15.0 or later on the 24 line, or 26.0.0
+or later. Node.js 23, 24.0–24.14 and 25 are not supported: this is the
+`engines` range of jsdom in the committed lockfile, the strictest of all the
+web dependencies.

-## Running it locally
-
-The developer setup (prerequisites, Authentik and Google clients, the
-`MEALQUEST_*` environment, `make dev` and the optional SearXNG sidecar) is
-runbook information and lives in CTXD: project `mealquest`, file
-`RUNBOOKS.MD`, section "Local development". Configuration is read only from
-the environment, and the service refuses to start, naming every missing or
-invalid variable.
+`make dev` runs the Go server on `:8080` and the Vite dev server on `:5173`
+(which proxies `/api`, `/auth` and `/media` to `:8080`). Open
+http://localhost:5173. Configuration is environment-only and fails fast:
+every variable above is required except the commented-out session
+lifetimes (when set they must be positive, with MAX at least IDLE) and
+trusted proxy list (every entry must be an IP or CIDR), and
+secrets are read only from files named by `*_FILE` variables. `MEALQUEST_PUBLIC_URL`, `MEALQUEST_OIDC_ISSUER` and the
+endpoints the issuer advertises must be `https://`; plain `http://` is
+accepted only for `localhost`, `127.0.0.1` and `[::1]`.

-All commands run on `10.60.1.14` as `overseer`, in bash, from the checkout
-`/home/overseer/mealquest`. A block that ends with `FAILED` or a non-zero
-`$?` stops the deploy: do not go on to the next step.
-
-## How the image carries its version
-
-`make docker` runs `docker build --build-arg VERSION=<version>` and tags the
-image `mealquest:<version>`, where `<version>` is
-`git describe --tags --always` of the checkout (a release tag such as
-`v1.0.0`, otherwise the short SHA), with `-dirty` added when a tracked file
-is modified. The [Dockerfile](../Dockerfile) links it into the binary, and
-`/health` reports it:
-
-```json
-{"status":"ok","version":"v1.0.0"}
-```
-
-Never pass `--build-arg VERSION` by hand, and never build with
-`docker compose build` or `docker compose up --build`: compose passes no
-version, so that image reports `dev`.
-
-The compose service `mealquest` runs the image named `mealquest-mealquest`
-(compose's name for the image it would build; check with
-`docker compose -f deploy/compose.yaml config --images mealquest`). It
-already exists, so `docker compose up` uses it and never builds. A deploy
-points that name at the `make docker` image with `docker tag`. Every
-`mealquest:<version>` image is kept for rollback; do not prune them.
-
-## Prerequisites
-
-- `make`, `git`, `curl`, `python3` and Docker Engine with Compose on the
-  host (`make` is not in the base install: `sudo apt-get install make`).
-- `deploy/.env` (git-ignored, owner `overseer`, mode 0600) sets every
-  variable [`deploy/.env.example`](.env.example) sets, with
-  `MEALQUEST_BIND_ADDRESS=10.60.1.14`. It must not set the variables
-  `deploy/compose.yaml` fixes (`MEALQUEST_HTTP_ADDR`, `MEALQUEST_DATA_DIR`,
-  `MEALQUEST_SEARXNG_URL` and the `*_FILE` variables). Creating it: CTXD
-  `RUNBOOKS.MD` "Stack and first deploy" > "3. Environment file".
-- `deploy/secrets/` (git-ignored, mode 0700) holds `secret_key`,
-  `oidc_client_secret`, `google_client_secret`, `vapid_private_key` and
-  `litestream_key`, each owned by `10001:10001` with mode 0600, and
-  `searxng.env`, owned by `overseer` with mode 0600. Creating them: CTXD
-  `RUNBOOKS.MD` "Stack and first deploy" > "4. Secrets".
-- The compose file is the checkout's [`deploy/compose.yaml`](compose.yaml);
-  the systemd unit [`mealquest.service`](systemd/mealquest.service) starts
-  and stops it and is the only way the stack starts.
-- DNS and Traefik already route `https://mealquest.cubecraftlabs.com` to
-  `10.60.1.14:8090` (CTXD `RUNBOOKS.MD` "Reverse proxy (Traefik)", "DNS").
-
-Check `deploy/.env` and the secrets before every deploy (a new release may
-add a variable; the service refuses to boot without it). Both commands must
-print nothing:
-
-```sh
-cd /home/overseer/mealquest
-comm -23 <(grep -oE '^MEALQUEST_[A-Z_]+' deploy/.env.example | sort -u) \
-         <(grep -oE '^MEALQUEST_[A-Z_]+' deploy/.env | sort -u)   # variables missing from deploy/.env
-sudo find deploy/secrets -type f ! -perm 600                       # secrets not mode 0600
-```
-
-## Deploy
-
-### 1. Build
-
-Record the release production is running now, check out the new release
-and build its image. Nothing restarts.
-
-The rollback target is the version the running service reports on
-`/health`, read before the checkout changes, never the checkout's `HEAD`:
-after a failed or deferred deploy the checkout can be ahead of production.
-The block resolves that version to a commit and prints it as the rollback
-SHA. A running version of `dev` or `*-dirty` names no commit: the block
-fails, and the rollback target must be established by hand before going on.
-
-The checkout must be clean (the same test as the Makefile's `GIT_DIRTY`:
-no modified tracked file outside the generated `internal/frontend/dist`).
-The block computes the image tag exactly as `make docker` does, `-dirty`
-included, and checks that image exists after the build.
-
-```sh
-cd /home/overseer/mealquest && (
-set -euo pipefail
-fail() { echo "$*" >&2; exit 1; }
-built=
-trap 'st=$?
-if [ "$st" -eq 0 ] && [ -n "$built" ]; then echo "built: $built"
-else [ "$st" -ne 0 ] || st=1; echo "build FAILED (status $st)" >&2; fi
-exit "$st"' EXIT
-bind=$(grep -E '^MEALQUEST_BIND_ADDRESS=' deploy/.env | cut -d = -f 2-)
-[ -n "$bind" ] || fail "deploy/.env sets no MEALQUEST_BIND_ADDRESS"
-running=$(curl -fsS "http://$bind:8090/health" | python3 -c 'import json, sys; print(json.load(sys.stdin)["version"])') \
-  || fail "http://$bind:8090/health did not return a version: no running release to roll back to"
-case "$running" in
-  dev|*-dirty) fail "the running release reports $running, which names no commit" ;;
-esac
-git fetch --tags origin
-rollback=$(git rev-parse --verify --quiet "$running^{commit}") \
-  || fail "running version $running is not a commit in this repository"
-echo "rollback SHA: $rollback (running version $running)"   # RECORD it for rollback
-git checkout --detach "refs/remotes/origin/main^{commit}"   # or the release tag, e.g. v1.0.0
-dirty=$(git status --porcelain --untracked-files=no -- . ':(exclude)internal/frontend/dist')
-[ -z "$dirty" ] || fail "the checkout has modified tracked files; clean it first:
-$dirty"
-v=$(git describe --tags --always)${dirty:+-dirty}   # the Makefile's VERSION
-make docker
-docker image inspect "mealquest:$v" > /dev/null 2>&1 || fail "no image mealquest:$v: the build failed"
-built="mealquest:$v"
-)
-```
-
-### 2. Ship and restart
-
-1. **Pre-restart gates.** Run CTXD `RUNBOOKS.MD` "Routine deploy and
-   rollback" > "Deploy" step 2 (a verified pre-deploy restore point; record
-   it with the rollback SHA) and step 3 (boot-required configuration). The
-   restart applies migrations the previous release refuses, so without that
-   restore point there is no rollback. If either fails, do not restart:
-   production stays on the previous release.
-2. **Point the stack at the new image and restart.** `docker compose pull`
-   fetches the pinned `litestream` and `searxng` images before anything
-   stops; `mealquest` is never pulled. The restart applies the firewall,
-   then runs `down` and `up -d`, and returns once `mealquest` passes its
-   healthcheck (`/health` inside the container).
-
-```sh
-cd /home/overseer/mealquest && (
-set -euo pipefail
-fail() { echo "$*" >&2; exit 1; }
-up=
-trap 'st=$?
-if [ "$st" -eq 0 ] && [ -n "$up" ]; then echo "restarted on: $up"
-else [ "$st" -ne 0 ] || st=1; echo "restart FAILED (status $st)" >&2; fi
-exit "$st"' EXIT
-v=$(git describe --tags --always)
-docker compose -f deploy/compose.yaml pull litestream searxng
-docker tag "mealquest:$v" mealquest-mealquest
-sudo systemctl restart mealquest
-for s in mealquest litestream searxng; do
-  id=$(docker compose -f deploy/compose.yaml ps --status running --quiet "$s")
-  [ -n "$id" ] || fail "$s is not running"
-done
-id=$(docker compose -f deploy/compose.yaml ps --quiet mealquest)
-health=$(docker inspect -f '{{.State.Health.Status}}' "$id")
-[ "$health" = healthy ] || fail "mealquest is $health, not healthy"
-up="mealquest:$v"
-)
-```
-
-On failure read `journalctl -u mealquest` and
-`docker compose -f deploy/compose.yaml logs mealquest`: a configuration
-error names the variable. Fix it or roll back.
-
-### 3. Verify the deployed version and a real screen
-
-A `/health` 200 alone proves only that some build is up. This step checks,
-on the LAN address and through Traefik, that:
-
-- `/health` reports exactly the checkout's `git describe --tags --always`;
-- `/` and the Plan screen's route `/plan` serve the built PWA shell (the
-  React root and a hashed `/assets/` script, not the placeholder page an
-  unbuilt embed serves);
-- that script is served as JavaScript.
-
-```sh
-cd /home/overseer/mealquest && (
-set -euo pipefail
-fail() { echo "$*" >&2; exit 1; }
-want=
-trap 'st=$?
-if [ "$st" -eq 0 ] && [ -n "$want" ]; then echo "deployed and verified: $want ($(git rev-parse HEAD))"
-else [ "$st" -ne 0 ] || st=1; echo "verification FAILED (status $st): the deploy is not verified" >&2; fi
-exit "$st"' EXIT
-v=$(git describe --tags --always)
-for base in http://10.60.1.14:8090 https://mealquest.cubecraftlabs.com; do
-  got=$(curl -fsS "$base/health" | python3 -c 'import json, sys; print(json.load(sys.stdin)["version"])') \
-    || fail "$base/health did not return a version"
-  [ "$got" = "$v" ] || fail "$base/health reports version $got, the checkout is $v"
-  for path in / /plan; do
-    page=$(curl -fsS "$base$path") || fail "$base$path did not return 200"
-    grep -q '<div id="root"></div>' <<< "$page" || fail "$base$path is not the PWA shell"
-    js=$(grep -oE 'src="/assets/[^"]+\.js"' <<< "$page" | head -n 1 | cut -d '"' -f 2) || true
-    [ -n "$js" ] || fail "$base$path references no built /assets/ script"
-    type=$(curl -fsS -o /dev/null -w '%{content_type}' "$base$js") || fail "$base$js did not return 200"
-    case "$type" in
-      text/javascript*) ;;
-      *) fail "$base$js is $type, not JavaScript" ;;
-    esac
-  done
-  echo "$base: version $got, PWA shell and $js served"
-done
-want=$v
-)
-```
-
-- `deployed and verified: <version> (<SHA>)` and `$?` = `0` → open
-  `https://mealquest.cubecraftlabs.com` in a browser: sign in and the Home
-  screen renders with the household's data. Then record the deployed
-  version and SHA, the rollback SHA, the pre-deploy restore point and the
-  date in the release's Maestro task.
-- `verification FAILED`, any error or a non-zero `$?` → the deploy is not
-  done. A version mismatch means the stack runs a different image than the
-  checkout: repeat step 2, or roll back.
-
-## Rollback to a previous release
-
-Rolling back points `mealquest-mealquest` at the previous release's
-`mealquest:<version>` image again; that release's checkout keeps the
-compose file and the version check consistent with it.
-
-1. **Check whether the rollback crosses a migration** with CTXD
-   `RUNBOOKS.MD` "Routine deploy and rollback" > "Rollback to a previous
-   SHA" (its first block), run against the rollback SHA that deploy step 1
-   recorded. If it prints versions unknown to the rollback SHA, restore the
-   database to the pre-deploy restore point first (CTXD `RUNBOOKS.MD`
-   "Restore the database", with `-timestamp <restore point>`); changes
-   since then are lost, so tell the household.
-2. **Check out the rollback SHA and retag its image.** An image built before
-   this runbook was not tagged `mealquest:<version>`; `make docker` builds
-   it from the same commit.
-
-```sh
-cd /home/overseer/mealquest && (
-set -euo pipefail
-fail() { echo "$*" >&2; exit 1; }
-P=<rollback SHA>   # recorded by step 1, from the running release's /health
-back=
-trap 'st=$?
-if [ "$st" -eq 0 ] && [ -n "$back" ]; then echo "rolled back to: $back"
-else [ "$st" -ne 0 ] || st=1; echo "rollback FAILED (status $st)" >&2; fi
-exit "$st"' EXIT
-git checkout --detach "$P"
-v=$(git describe --tags --always)
-docker image inspect "mealquest:$v" > /dev/null 2>&1 || make docker
-docker image inspect "mealquest:$v" > /dev/null 2>&1 || fail "no image mealquest:$v"
-docker tag "mealquest:$v" mealquest-mealquest
-sudo systemctl restart mealquest
-back="mealquest:$v"
-)
-```
-
-3. **Run step 3 above** unchanged. The rollback is done only when it prints
-   `deployed and verified:` with the previous release's version.
-
-## Automated deploys
-
-[`auto-deploy.sh`](auto-deploy.sh), installed as
-`/usr/local/sbin/mealquest-auto-deploy`, runs this runbook's deploy unattended:
-step 1 (build), the prerequisite `deploy/.env` and secrets check, CTXD
-`RUNBOOKS.MD` "Deploy" steps 2 (pre-deploy restore point) and 3
-(boot-required configuration), step 2 (ship and restart) and step 3
-(verify). No check is skipped or weakened, and it stops at the first
-failure. Every failure before the restart leaves production on the previous
-release.
-
-### What runs, and when
-
-[`mealquest-auto-deploy.timer`](systemd/mealquest-auto-deploy.timer) starts
-[`mealquest-auto-deploy.service`](systemd/mealquest-auto-deploy.service)
-at every quarter hour (`OnCalendar=*-*-* *:0/15:00`), plus up to 5 minutes'
-random delay; a check missed while the host was down runs as soon as it is
-back (`Persistent=true`). The service runs the script as `overseer` from the
-checkout, and only while `mealquest.service` is active: a stack stopped on
-purpose (a database or media restore) is skipped, not redeployed. Output goes
-to the journal (`journalctl -u mealquest-auto-deploy`).
-
-Each run fetches `origin` and compares `origin/main` with the last
-`deployed=` SHA in the deploy record `/home/overseer/mealquest-auto-deploy.log`:
-
-| `origin/main` | Result |
-| --- | --- |
-| is the last deployed SHA | No-op: exit 0, no output. |
-| CI (Gitea commit status) `pending` | Exit 0, no output; the next run checks again. |
-| CI `failure`, `error`, `warning`, or no status yet | Error in the journal, exit 1, nothing deployed. |
-| the last record line is `FAILED` for this SHA | Error in the journal, exit 1, nothing deployed: a failed deploy is never retried by the timer. |
-| CI `success` | Deploy. |
-
-The CI status is read from
-`https://code.cubecraftlabs.com/api/v1/repos/Maniacs_Mansion/MealQuest/commits/<SHA>/status`
-(public; no credential). A commit merged moments before a run can briefly
-report no status, which fails that run; the next run reads it again.
-
-A deploy appends one line to the record:
-
-```text
-2026-10-12T15:04:05Z previous=<rollback SHA> deployed=<SHA> restore_point=2026-10-12T15:01:59Z
-```
-
-`previous` is the rollback SHA (from the running release's `/health`,
-never the checkout) and `restore_point` the verified pre-deploy restore
-point: record both in the release's Maestro task. A failed deploy appends
-`<date> FAILED target=<SHA> status=<exit status>` and logs
-`auto-deploy FAILED (status <n>)` to the journal, adding whether it failed
-before the restart (production untouched) or after it (read
-`journalctl -u mealquest`, then fix or roll back). Either way the checkout is
-left at the target commit; the running release on `/health` stays the
-rollback target.
-
-### Install on the host
-
-The script and units are installed copies: repeat this whenever a release
-changes `deploy/auto-deploy.sh` or the units. From the checkout, at a release
-that contains them:
-
-```sh
-cd /home/overseer/mealquest
-sudo install -m 0755 deploy/auto-deploy.sh /usr/local/sbin/mealquest-auto-deploy
-sudo install -m 0644 deploy/systemd/mealquest-auto-deploy.service \
-  deploy/systemd/mealquest-auto-deploy.timer /etc/systemd/system/
-sudo systemctl daemon-reload
-```
-
-The timer refuses to deploy until the record holds a deploy, so seed it with
-one manual deploy of the release production should run (below), then start
-the timer:
-
-```sh
-sudo /usr/local/sbin/mealquest-auto-deploy --ref refs/remotes/origin/main
-sudo systemctl enable --now mealquest-auto-deploy.timer
-systemctl list-timers mealquest-auto-deploy.timer
-```
-
-To stop automated deploys: `sudo systemctl disable --now mealquest-auto-deploy.timer`.
-
-### Manual override
-
-```sh
-sudo /usr/local/sbin/mealquest-auto-deploy --ref <ref>
-```
-
-deploys an explicit ref (a SHA, tag or `origin/<branch>`) through the same
-blocks, bypassing the CI and no-op gates: for a roll-forward fix, a re-run
-after a `FAILED` record, or seeding the record. Run as root, the script
-re-executes itself as `overseer`; it holds a lock, so it never runs alongside
-the timer's run. It prints `deployed and verified:` and exits 0 only when
-step 3 passed.
-
-### Rollback
-
-Rollback is not automated: follow "Rollback to a previous release" above
-and CTXD `RUNBOOKS.MD` "Routine deploy and rollback" > "Rollback to a
-previous SHA", using the `previous` SHA and `restore_point` from the record.
-The timer does not undo a manual rollback: `origin/main` is still the last
-recorded deploy, so its runs are no-ops until `main` moves, and a new `main`
-then deploys as usual. Disable the timer if the rollback must hold.

-# Nightly copy of the MealQuest media directory (recipe and dinner photos)
-# to the Synology NAS. The database itself is replicated continuously by
-# Litestream; this covers the files beside it.
-#
-# Runs as the unprivileged app user (10001, host user "mealquest"), never
-# root: mealquest-media-backup.service bind-mounts the data volume
-# read-only at /run/mealquest-data and hands the NAS key in as a systemd
-# credential. Anything the app could plant in the volume is therefore read
-# with the app's own permissions only.
-#
-# The script changes into the media directory and checks that the physical
-# path is the expected one, so a media path that is a symlink is refused.
-# rsync then copies "./" — the directory the shell is already in — so
-# swapping the path afterwards cannot redirect it. Symlinks inside the
-# directory are copied as links (-a), never followed.
-#
-# The media directory is created at deploy time (CTXD project mealquest,
-# RUNBOOKS.MD "Media — nightly rsync"). If it is missing the job fails; it
-# is never treated as "nothing to back up".
-#
-# rsync mirrors into .../mealquest-backups/media/ only: the target ends in
-# a slash, so --delete removes files from that directory and nothing
-# outside it. Re-runs transfer only what changed. Output goes to the

-"""Generate folds_table.go, the letter-fold table used by harness.Normalize,
-and its copy web/src/dinners/letterFolds.json, used by the PWA's
-normalizeName (web/src/dinners/names.ts). TestLetterFoldsMatchPWA fails when
-the two differ.
-
-Run from this directory with `go generate ./internal/ai/harness` (or
-`python3 gen_folds.py`; gofmt must be on PATH). It uses only the Python
-standard library's unicodedata, so it works offline; the Unicode version it
-was generated from is recorded in the output.
-
-The table maps a code point to its lowercased base letters:
-
-  - every code point with a canonical decomposition that includes a
-    combining mark (category Mn) maps to its full canonical decomposition
-    with the marks removed, so a precomposed letter folds exactly like its
-    decomposed spelling once Normalize drops the marks (ở -> o, ǖ -> u).
-    Code points whose remaining base is not letters or digits (spacing
-    accents such as U+1FEE) are left out; Normalize treats both spellings
-    of those as punctuation;
-  - Latin letters with no decomposition whose name is "LATIN ... LETTER X
-    WITH ..." map to x (ø -> o, ł -> l, đ -> d);
-  - the Latin ligatures and letters listed in EXTRA map as given.
-
-Each result is then folded again, letter by letter, until nothing changes
-(ǿ -> ø -> o, ǽ -> æ -> ae). Normalize writes a result without folding it
-again, so the table must already be fully reduced; the generator fails if a
-result does not settle.
-
-Hangul syllables are left out: their decomposition is into conjoining jamo,
-not combining marks.

-# Anthropic adapter fixtures
-
-These are the Messages API response bodies the contract tests in
-`anthropic_test.go` replay. They are **not live captures**. Product AI is
-tested with fakes, and live vendor calls are opt-in and never use
-credentials, so no request was sent to Anthropic to make them. Each fixture
-is a sanitized adaptation of the response shapes in Anthropic's public API
-documentation:
-
-- Messages: <https://docs.anthropic.com/en/api/messages>
-- Tool use, including `tool_choice` `{type: tool}`:
-  <https://docs.anthropic.com/en/docs/build-with-claude/tool-use>
-- List models: <https://docs.anthropic.com/en/api/models-list>
-- Errors: <https://docs.anthropic.com/en/api/errors>
-
-Sanitizing:
-
-- IDs, request IDs, timestamps and token counts are illustrative values in
-  the documented format, not values from a real account.
-- Message content and tool input are replaced with MealQuest dinner text.
-- No real credential appears anywhere. `{{KEY}}` is a placeholder the tests
-  replace with a fake key, to prove the adapter redacts a key echoed back in
-  a vendor body.
-
-Below, *not in the public example* marks fields or values that were added
-for a test case and do not come from the documented example.
-
-| Fixture | Shape | Not in the public example |
-| --- | --- | --- |

-# Ollama adapter fixtures
-
-These are the native Ollama API response bodies the contract tests in
-`ollama_test.go` replay. They are **not live captures**. Product AI is tested
-with fakes and live vendor calls are opt-in, so no request was sent to an
-Ollama server to make them. Each fixture is a sanitized adaptation of the
-response shapes in Ollama's public API documentation
-(<https://github.com/ollama/ollama/blob/main/docs/api.md>):
-
-- Chat, non-streaming: `POST /api/chat` with `"stream": false`.
-- Structured outputs: `POST /api/chat` with a JSON schema in `"format"`.
-- List local models: `GET /api/tags`.
-- Errors: a JSON `{"error": "..."}` body with a non-2xx status; a model
-  that is not pulled is HTTP 404.
-
-Sanitizing:
-
-- Timestamps, durations, sizes, digests and token counts are illustrative
-  values in the documented format, not values from a real server.
-- Message content is replaced with MealQuest dinner text.
-- Ollama takes no credentials, so none appear.
-
-Below, *not in the public example* marks values that were added for a test
-case and do not come from the documented example.
-
-| Fixture | Case | Shape | Not in the public example |
-| --- | --- | --- | --- |
-| `chat_text.json` | Success | Finished chat message, `done_reason: stop`, `prompt_eval_count` and `eval_count`. | — |
-| `chat_schema.json` | Schema output | Finished chat message whose content is a JSON object string. | The dinner object. |
-| `error_model_not_found.json` | Model missing | `{"error": "model \"…\" not found, try pulling it first"}`, served with HTTP 404. | — |
-| `tags.json` | Model list | `{"models": [...]}` with `name`, `model`, `digest` and `details`. | — |
-
-The unreachable-host case has no fixture: there is no response to record.
-The tests close an `httptest` server and dial its address, so the
-connection is refused, and they hold a reply past a short deadline for the
-timeout.

-# OpenAI-compatible adapter fixtures
-
-These are the vendor response bodies the contract tests in `openai_test.go`
-replay. They are **not live captures**. Product AI is tested with fakes, and
-live vendor calls are opt-in and never use credentials, so no request was
-sent to a vendor to make them. Each fixture is adapted from the response
-shape in that vendor's public API documentation or open source, then
-sanitized:
-
-- IDs, timestamps, fingerprints and token counts are illustrative values in
-  the documented format, not values from a real account.
-- Message content is replaced with MealQuest dinner text.
-- No real credential appears anywhere. `{{KEY}}` is a placeholder the tests
-  replace with a fake key, to prove the adapter redacts a key echoed back in
-  a vendor body.
-
-The tests check the adapter against these bodies with independent
-assertions on both the request sent (path, headers, `response_format`,
-messages) and the response decoded. The request side does not depend on the
-fixtures.
-
-Below, *not in the public example* marks fields or values that were added
-for a test case and do not come from the vendor's documented example.

-## OpenAI
-
-Sources: API reference, "The chat completion object" and "List models"
-(<https://platform.openai.com/docs/api-reference/chat/object>,
-<https://platform.openai.com/docs/api-reference/models/list>); the
-Structured Outputs guide, for `refusal`
-(<https://platform.openai.com/docs/guides/structured-outputs>); and the error
-codes guide (<https://platform.openai.com/docs/guides/error-codes>).
-
-| Fixture | Shape | Not in the public example |
-| --- | --- | --- |
-| `openai_chat_json_schema.json` | Chat completion object with `usage` details, `service_tier`, `system_fingerprint`. | The JSON reply content. |
-| `openai_chat_refusal.json` | Structured Outputs refusal: `content: null`, `refusal` set. | — |
-| `openai_models.json` | `{object: list, data: [model]}`. | — |
-| `openai_error_invalid_key.json` | Error object, `code: invalid_api_key`, message echoing the key. | The full key in the message; OpenAI masks most of it. Kept whole to test redaction. |
-| `openai_error_server.json` | Error object, `type: server_error`. | The `Authorization: Bearer {{KEY}}` text; added to test redaction. |
-
-## OpenRouter
-
-Sources: API reference, chat completion response and errors
-(<https://openrouter.ai/docs/api-reference/overview>,
-<https://openrouter.ai/docs/api-reference/errors>), and "List available
-models" (<https://openrouter.ai/docs/api-reference/list-available-models>).
-
-| Fixture | Shape | Not in the public example |
-| --- | --- | --- |
-| `openrouter_chat_json_object.json` | Chat completion with `provider`, `native_finish_reason` and `message.reasoning`. | The JSON reply content. |
-| `openrouter_chat_upstream_error.json` | An `error` object (`code`, `message`, `metadata.provider_name`, `metadata.raw`) in an HTTP 200 body, which OpenRouter documents for upstream failures. | `user_id`. |
-| `openrouter_error_rate_limited.json` | Error object, `code: 429`, rate-limit `metadata`. | The `Key {{KEY}}` text; added to test redaction. |
-| `openrouter_models.json` | `{data: [model]}` with `name`, `context_length`, `architecture`, `pricing`, `supported_parameters`. | The second model is a minimal entry, to test optional fields. |

-## Ollama
-
-Ollama's OpenAI compatibility page
-(<https://github.com/ollama/ollama/blob/main/docs/openai.md>) documents
-requests but shows no response bodies. The shapes come from its `openai`
-middleware source (<https://github.com/ollama/ollama/blob/main/openai/openai.go>):
-`chatcmpl-<n>` IDs, `system_fingerprint: fp_ollama`, `owned_by: library` on
-models, and errors as `{error: {message, type: api_error, param, code}}`.
-
-| Fixture | Shape | Not in the public example |
-| --- | --- | --- |
-| `ollama_chat_text.json` | Plain chat completion. | — |
-| `ollama_chat_prompt_only.json` | Chat completion. | The reply text: prose and stray braces around a fenced JSON object, to test prompt-only extraction. |
-| `ollama_chat_truncated.json` | Chat completion with `finish_reason: length`. | The cut-off JSON reply. |
-| `ollama_models.json` | `{object: list, data: [model]}`. | — |
-| `ollama_error_not_found.json` | Middleware error object for a missing model. | — |
