chore(plugin-sdk): make it npm-publishable so npx resolves for authors

The docs told authors to run `npx create-trek-plugin` / `npx trek-plugin`,
but nothing published under those names, so npx couldn't resolve them.

- Ship one package, `trek-plugin-sdk`, with a bin that matches the package
  name (`trek-plugin-sdk`) so `npx trek-plugin-sdk <command>` resolves with
  zero install. The dispatcher gained a `create` subcommand, so every step
  (create/validate/pack/entry/release) runs through that one entry point.
  The short `trek-plugin` / `create-trek-plugin` bins still work once
  installed.
- Package hardening for publish: repository+directory (monorepo subdir),
  homepage/bugs/author/engines, publishConfig public, a prepublishOnly that
  builds + tests, and a LICENSE file.
- A publish workflow: pushing a `plugin-sdk-v*` tag builds and publishes with
  the NPM_TOKEN repo secret.
- Docs (SDK README + the four wiki pages) now use `npx trek-plugin-sdk <cmd>`,
  the invocation that actually resolves.

-# The stable release. Dispatched by hand on main, it:
-#   1. refuses to run unless ci-ok passed on the main commit it releases,
-#   2. works out the version from the tags and the bump input,
-#   3. asks the TREK services issuer for the registration dialect of that
-#      version and checks it, in a job without write access
-#      (registration-dialect.yml); without one the release ships the dialect
-#      already on main, but only while that one still has 90 days to run,
-#   4. commits the bump to package.json, the lockfile, Chart.yaml and the
-#      dialect, tags it and pushes,
-#   5. builds both platforms from exactly that bump commit (never from
-#      whatever main points to by then) and publishes :VERSION,
-#      :MAJOR.MINOR, :MAJOR and :latest,
-#   6. publishes the Helm chart from the same commit.
-#
-# Big or risky changes go out as a prerelease first (docker-dev.yml, tagged
-# :latest-pre and :<next>-pre.N); bump=auto here then finalizes that line.
-# Without a prerelease in flight there is no default: the run stops until
-# someone picks patch, minor or major.
-#
-# Each stable release registers new installations in a dialect of its own,
-# which the issuer accepts for 180 days, and for as long as it is the newest
-# release's; renewing a key needs none. dev gets the module when main is merged
-# back into dev after the release; a prerelease asks the issuer for one of its
-# own (docker-dev.yml). The issuer's side, and what to set up before the first
-# release with a dialect, is in the operations guide of the TREK services.

-Guidance for Claude Code in this repository. This file holds the commands, the invariants, the gates and the philosophy. Inventories (file lists, counts, history) deliberately live in the code and its READMEs, not here — when this file disagrees with the code, the code wins; fix the doc.
-
-## What TREK is
-
-A self-hosted, real-time collaborative travel planner. npm-workspaces monorepo:
-
-- **`shared/`** (`@trek/shared`) — Zod schemas, the **single source of truth** for API contracts, plus all i18n locales. Must be built before server/client typecheck or run.
-- **`server/`** (`@trek/server`) — NestJS API (Express adapter), SQLite via `better-sqlite3`, WebSocket sync, built-in MCP server, sandboxed plugin runtime.
-- **`client/`** (`@trek/client`) — React 19 + Vite + Zustand + Tailwind PWA, offline-first via Dexie/IndexedDB.
-- **`plugin-sdk/`** (`trek-plugin-sdk`) — **not a root workspace**: own lockfile, published to npm independently, must ship standalone. Run its commands from `plugin-sdk/`.
-
-Each package has its own `CLAUDE.md`; this file covers the monorepo picture.
-
-## Commands
-
-Run from the repo root unless noted. **Use `npm run ... --workspace=<pkg>`, not `npm -w <pkg>`**.
-
-```bash
-npm run dev                       # build shared, then watch shared + server + client concurrently
-npm run build                     # build shared → server → client (order matters)
-npm run lint                      # lint all three workspaces, check-only (npm run lint:fix applies the fixes in shared and server)
-npm run format                    # prettier --write all three
-npm run lint:knip                 # knip over client/server/shared (knip.jsonc): unused files, exports, types, deps may only shrink against scripts/ci/knip-baseline.json (CI gate; --update lowers it)
-```
-
-Tests:
-
-```bash
-npm run test                                       # all workspaces
-npm run test --workspace=server                    # vitest run (server); also test:unit / test:integration / test:ws
-npm run test:e2e                                   # server e2e (boots Nest against a temp SQLite)

-cd client && npm run lint:rtl                      # physical left/right sides may only shrink per file (CI gate)
-cd client && npm run lint:dup                      # lines in copied code may only shrink per file, at SonarCloud's thresholds (CI gate)
-cd client && npm run lint:pairs                    # desktop and phone views of a feature import its shared hook; every phone screen is listed (CI gate)
-cd client && npm run lint:size                     # no source file past 1000 lines, longer ones only shrink (CI gate; server has the same)
-cd client && npm run lint:strict                   # strictNullChecks + noImplicitAny errors may only shrink per file; new files start at zero (CI gate)
-cd client && npm run lint:warnings                 # eslint (typed) errors fail, warnings per rule may only shrink, new rules start frozen (CI gate)
-cd server && npm run lint:warnings                 # the same for the server, against server/scripts/eslint-baseline.json (CI gate)
-cd server && npm run lint:format                   # Prettier outside the baseline list (CI gate; shared has the same in lint-prettier.yml)
-cd server && npm run lint:strict                   # strict type errors per file may only shrink, a new file has none (CI gate)
-cd client && npm run lint:format                   # Prettier outside the baseline list (CI gate)
-cd client && npm run lint:layers                   # components never import pages/ or mobile/ (CI gate)

-npm run typecheck --workspace=server               # tsc --noEmit (also client/shared; server also has typecheck:tests)
-```
-
-Run a single test file or test:
-
-```bash
-npx vitest run tests/unit/nest/weather.controller.test.ts   # (from server/ or client/)
-npx vitest run -t "name of the test"                        # by test-name pattern
-```
-
-i18n parity (CI gate — every non-`en` locale must have the identical file set and top-level keys):
-
-```bash
-npm run i18n:parity --workspace=shared            # audit (exit 0)
-npm run i18n:parity:strict --workspace=shared     # CI gate (exit 1 on drift)
-```
-
-Dev ports: the server listens on **3001**; the Vite dev server proxies the API, websocket, uploads, MCP and OAuth paths to it (see `client/vite.config.js`). `.nvmrc` pins the Node major the Docker image runs and every CI job reads; `engines` in each package.json states the range that installs (npm only warns outside it). `server/.env.example` is the env-var reference.
-
-## Server invariants
-
-Nest owns everything: every domain is a DI module under `server/src/nest/<domain>/` (`controller` + `service` + `module`, registered in `app.module.ts`), and ESLint refuses imports of the deleted legacy `services/` layer. `server/src/nest/README.md` is the module blueprint; **`weather/` is the reference implementation** — copy its shape. The domain's Zod contract lives in `shared/src/<domain>/`.
-
-- **`bootstrap.ts` — `buildApp()`** is the single builder for production and the test harness. **Composition order is load-bearing**: everything registered on the raw Express instance must come **before `app.init()`**, because Nest's router throws `NotFoundException` on unmatched routes and nothing registered after init is reachable. Don't add routes to that pre-init shell — it bypasses every global guard, interceptor and filter.
-- **`/mcp` bodies are raw by design** — the parser wrappers exempt `/mcp` so the MCP SDK reads the untouched stream; never `@Body()` a `/mcp` route.
-- **Auth is default-deny**: global guards run as `APP_GUARD`s; public routes opt out with `@Public()`, and a boot-time ratchet (`validate-route-guards.ts`) refuses any public route not on its allow-list.
-- **Trip-scoped routes** verify trip access (404) and the permission (403) — `@UseGuards(JwtAuthGuard, TripAccessGuard)` + `@RequirePermission('<action>')` per handler — and forward `X-Socket-Id` to the broadcast so the originating client doesn't echo its own change. **Never gate a multipart upload with a guard** (the client sees ECONNRESET instead of 403 — check in the handler).
-- **DB** (`server/src/db/`): `better-sqlite3`, WAL, FK on. MikroORM's migrations (`db/migrations/`) are the only schema source, **including for tests** — the hand-kept `schema.ts`/`migrations.ts`/`seeds.ts` test builders are gone. Seeding is MikroORM's too (`db/seeders/`), applied at boot from `buildApp()`; the ORM shares the one better-sqlite3 connection (bound in `server/src/db/orm-driver.ts`) rather than opening its own. Queries go through repositories (`server/src/db/repositories/`) and `UnitOfWork` (`server/src/nest/database/unit-of-work.ts`) for transactions — there is no `DatabaseService`. `better-sqlite3` itself is ESLint-restricted to `src/db/` plus a short, named allow-list (`server/eslint.config.mjs`), so a domain reaching for the driver directly fails lint. `NODE_ENV=test` gives each vitest worker an isolated `:memory:` DB.
-- **Realtime**: `/ws` is a Nest gateway in `server/src/nest/realtime/` — inject `RealtimeService`. Tests observe broadcasts through a `FakeRealtimeService` (`server/tests/helpers/fake-realtime.ts`), never by mocking the transport module.
-- **MCP**: tools are declared in `<domain>.mcp.ts` files beside each module, on the `server/src/nest-mcp/` decorator layer. A validation or permission change on a REST route must land in the parallel MCP tool in the same change. See `MCP.md`.
-- **Addons** are admin-toggleable feature modules keyed by `ADDON_IDS` in `server/src/addons.ts`.
-- **Plugins** (`server/src/nest/plugins/`): one forked child process per plugin, permission-gated RPC (a handler is registered only if the plugin holds the unlocking permission), install-time manifest/signature/egress/version-range gates. The protocol tables are **generated** into `plugin-sdk/` and `shared/` by `gen:plugin-facts`; `check:plugin-facts` is the CI gate. Author tooling is `plugin-sdk/`; the `trek-plugin-dev` skill covers authoring.
-- **Storage**: uploads go through the driver abstraction in `server/src/nest/storage/` (local / S3 / mirror). Never touch the filesystem or the S3 SDK from a domain service.
-- **Crons** go through `server/src/nest/scheduling/` only — never a `@Cron` decorator (it bypasses the test-time gate).
-
-## Client invariants
-
-Offline-first, with a layered data flow. A Page never owns state directly:
-
-- **Page pattern** (enforced by `lint:pages`, spec in `client/src/pages/PATTERN.md`): a `*Page.tsx` is a **wiring container** composing a co-located `use<Page>()` hook; it must not call React state/effect/memo hooks itself.
-- **Data flow**: `store (Zustand, client/src/store/) → repo (client/src/repo/) → api (client/src/api/) | Dexie (client/src/db/offlineDb.ts)`. Writes go through `client/src/sync/mutationQueue.ts`: optimistic Dexie write, then a replay with an `X-Idempotency-Key` header on reconnect. `client/src/store/slices/remoteEventHandler.ts` applies incoming WebSocket events. Components never call the API directly.
-- **Styling**: semantic Tailwind tokens (`bg-surface*`, `text-content*`, `border-edge*`, `bg-accent*`) or the underlying `var(--token)` variables — never color literals, arbitrary-value color classes or numeric inline `fontSize`, so user-chosen scheme/transparency/text-size keep working. `theme:lint` holds the bypasses per file to a baseline that only shrinks (CI gate); mark intentional exceptions (map/PDF/brand) with a `theme-lint-disable` line comment, which is counted too.
-- **Reading direction**: Arabic runs the app right to left, so spacing, insets and alignment that follow the text use the logical forms (`ms-`/`me-`/`ps-`/`pe-`/`start-`/`end-`/`text-start`/`border-s`/`rounded-s`, `marginInlineStart`, `insetInlineEnd`, `textAlign: 'start'`). `lint:rtl` counts the physical ones per file against `client/scripts/rtl-baseline.json`, which may only shrink; geometry that is physical on purpose in new code (maps, measured positions, time axes) carries an `rtl-lint-disable` comment.
-- **PWA**: `vite-plugin-pwa` + Workbox cache tiles, API and uploads; `prebuild` generates icons.
-
-## Shared contracts & i18n
-
-- A route is "done" only once its contract lives in `shared/` and both sides import the inferred types. Edit the Zod schema, rebuild shared, then server (validation + DTO types) and client (typed requests) pick it up.
-- Locale files live in `shared/src/i18n/<locale>/`, one file per domain; `en/` is canonical. When you add or change a key, **add a real translation to every locale** — parity fails CI on missing keys, and an English placeholder is not acceptable in a non-`en` locale.
-- Count-bearing strings are plural groups: the key holds the general form and `key.one`, `.few` … the forms the language's `Intl.PluralRules` selects. Pass `{ count }` as a number and never choose between two keys with `count === 1`; details in `shared/CLAUDE.md`.
-
-## Project direction
-
-These principles come out of a full-repo audit and shape all new code:
-
-- **Protect the crown jewels.** The client's offline-first data core (repos + mutation queue + Dexie), the out-of-process plugin sandbox, the Zod contract layer, and the auth primitives are production-grade. Extend them; never route around them or rewrite them in anger.
-- **No "modern shell over legacy core."** The debt pattern is a modern frame delegating to the old approach underneath (on the client: feature components calling the raw API past the offline core). New code goes all-in on the target architecture; when touching a legacy seam, migrate it rather than adding another wrapper.
-- **Single source of truth over manual synchronization.** Never add a hand-mirrored copy of state, schema, or contract (server↔Dexie↔Zustand, schema↔SQL, the plugin contract). Derive from one source, or guard the copy with a parity test that cannot silently skip — the server entities are the precedent: `npm run gen:entities`/`check:entities --workspace=server` (`server/scripts/generate-entities.ts`) regenerate them from the live migrated schema instead of hand-editing, and a parity test (PARITY-009) pins entity-vs-DB drift (delete rules, index names) at zero skips. The Kysely table types the repositories query through are generated the same way (`gen:db-types`/`check:db-types`, `server/scripts/generate-db-types.ts`).
-- **DI over global mutable module state.** New server code injects its dependencies; new client code avoids `window`-global buses and mutable module state.
-- **Use the runtime's native idioms.** Prefer React 19 features (`useOptimistic`, Actions, `use()`/Suspense) and Nest subsystems (providers, pipes, guards, `@nestjs/schedule`) over hand-rolled equivalents.
-- **Fail closed, gates stay on.** Security switches default to safe; misconfiguration must refuse, not degrade. Never lower a quality gate to land a change — no new `any`, no new `eslint-disable`, no downgrading rules to `warn`, no lowered coverage thresholds.
-
-## Conventions (from CONTRIBUTING.md)
-
-- **Target the `dev` branch** for PRs, not `main` (exception: `wiki/`-only changes).
-- **Discuss first**: outside contributions are pitched in the `#github-pr` Discord channel before any code is written.
-- **PRs follow `.github/PULL_REQUEST_TEMPLATE.md`** and need a linked issue (`Closes #N`) for fixes or an approved feature discussion for features.
-- **Conventional commits** (`fix(maps): ...`, `feat(budget): ...`). **No Co-Authored-By or other tool-attribution trailers.**
-- One focused change per PR; no breaking changes; no unrelated reformatting. Tests ship in the same change — the project holds 80%+ coverage.
-- **Parity is law** when touching a route: same URL, method, query/body, HTTP status, `Set-Cookie` and JSON body, including bespoke error strings. Nest defaults POST to 201 — add `@HttpCode(200)` where the contract returns 200. Declare static sub-routes (`/reorder`) **before** `:id` param routes.
-
-## Quality gates in CI
-
-`.github/workflows/test.yml` runs, per package: typecheck (server also `typecheck:tests`, client also the strict-mode ratchet `lint:strict`), lint (client and server through `lint:warnings`, which also holds the warning count per rule), `lint:pages`, `lint:rtl`, `lint:size` (client and server), the server's `lint:strict`, `lint:boundaries`, `lint:tx`, `lint:dialect`, `lint:test-sql`, `lint:test-mocks`, `lint:test-new-service`, `lint:query-api`, `lint:mcp-zod`, `lint:service-http` and `lint:response-contracts`, the client's and server's `lint:format`, `lint:layers`, `lint:offline`, `lint:dup`, `lint:pairs`, `lint:skips`, `lint:i18n-keys` and `theme:lint`, shared's `contracts:open`, the repo-wide `lint:knip` (in server-lint-checks), `check:plugin-facts`, `i18n:parity:strict` (with the untranslated-strings ratchet), the S3 contract suite, the Postgres probe (`postgres-probe`: every dialect helper on SQLite and Postgres, and the statements every repository method reaches with sample arguments against a Postgres service; the SQL errors per method and the list of methods it cannot measure are held to a baseline that only shrinks and fails while it is still unmeasured; see `server/CLAUDE.md`), the browser end-to-end flows (Chromium and WebKit), a client build with `check:gl-split`, coverage for all four packages, then a SonarCloud scan. It also builds the Docker image and boots it until `/api/health/ready` answers (`docker-image`), and lints and renders the Helm chart against the Kubernetes schemas and runs `docker compose config` on every compose file (`deploy-manifests`). `lint-prettier.yml` additionally runs `lint` + `lint:format` on `shared/`, both check-only. `plugin-sdk` has no lint script and is outside the eslint gates. **Not in CI**: the screenshot and help-media Playwright projects; run them locally. There are no git hooks; nothing runs before a commit except you. Other workflows build Docker images, scan them, and publish `trek-plugin-sdk` on `plugin-sdk-v*` tags.
-
-- **Job names read "package: what"** (`Server: Types`, `Client: Tests 3/7`), and the list at the top of `test.yml` says what each job holds. A new job follows the scheme and joins that list, and the job-count note there says when a long job needs a slot freed first.
-- **Tests run beside the gates, in shards.** The client and server suites run in slices on parallel runners (`client-tests`, `server-tests`, through each package's `vitest.shard.config.ts`), and `client-coverage`/`server-coverage` merge their blob reports and check the thresholds against the whole. A red slice is usually a failing test, a red merge job usually a threshold.
-- **`ci-ok` is the required check.** The branch ruleset requires `ci-ok` (plus `lint` and `check-target` from their own workflows), and `ci-ok` needs every job above except the scan. It fails if any of them failed or was cancelled and passes if they passed or were skipped. A new gate job counts only once it is listed in `ci-ok`'s `needs:`.
-- **Guides name paths that exist**: the `changes` job runs `scripts/ci/doc-paths.mjs`, which resolves every backtick path in the CLAUDE.md files, `README.md`, `server/src/nest/README.md` and the wiki against the tracked files; the missing ones are listed in `scripts/ci/doc-paths-baseline.json`, which only shrinks (`--update` after a fix).
-- **What runs is decided by `changes`, not by `on.paths`**: `scripts/ci/changed-areas.mjs` maps the changed files to the `code`, `image` and `deploy` areas (tests: `npm run test:ci-scripts`). A path filter on the workflow would leave `ci-ok` unreported on a docs-only PR and block it. Add a new top-level file the build reads to the right area there.
-- **Runners and Node**: jobs run on `ubuntu-24.04`, not `ubuntu-latest`, and every `setup-node` reads `.nvmrc`. Third-party actions (anything outside `actions/*`) are pinned by commit SHA with the tag in a comment; Dependabot keeps both current.
-- **Security scans are advisory.** `security.yml` runs `npm audit` (what the image installs, plus `plugin-sdk`) on every PR and push into dev and main, and Docker Scout on the built image for main. Neither is required: a newly published advisory would turn every open PR red at once. Fixes are held as floors in the root `package.json` `overrides`; npm ignores an `overrides` block in a workspace `package.json`, so never put one there.
-- **Releases** are dispatched by hand and refuse a commit whose `ci-ok` is not green. `docker-dev.yml` (any branch, usually dev) is the canary: it builds the dispatched commit as the next minor or major `-pre.N` and moves only `:latest-pre` and `:<major>-pre`. `docker.yml` (main only) bumps the version, commits and tags it, builds both platforms from exactly that commit and moves `:latest`, `:<major>`, `:<major>.<minor>` and `:<version>`. Its `bump=auto` only finalizes a prerelease in flight; without one it stops and asks for patch, minor or major. Ship a release that migrates or changes a lot as a prerelease first, and as a minor, so installs pinned to `:<major>.<minor>` can wait it out.
-
-**SonarCloud** (project `liketrek_TREK`, the built-in Sonar way gate; the run takes 20–25 min, so get it right before pushing) measures **new code only** on a PR; any failing condition blocks it:
-
-| Condition (new code) | Must be |
-|---|---|
-| Coverage | ≥ 80% |
-| Duplicated lines | ≤ 3% |
-| Security / reliability / maintainability rating | A |
-| Security hotspots reviewed | 100% |
-
-- **Duplication is the one that bites.** Desktop and phone shells (`client/src/components/<X>` ↔ `client/src/mobile/screens/.../M<X>`) are deliberate mirrors of each other's markup; their logic lives in one shared hook per feature. Every line added identically to both counts against the 3% budget, so a feature touching both shells fails on its own. Put the logic in ONE hook/module (precedents: `useInstanceSettings`, `useRangeBypass` under `client/src/components/Admin/`) and leave only markup in each shell. `lint:dup` finds the same copies in `client/src` before the push and holds every file to `client/scripts/dup-baseline.json`; `lint:pairs` holds each pair in `client/scripts/feature-pairs.json` to its shared hook and makes every new phone screen either join a pair or say why it has no twin. Locale files are excluded from duplication, so i18n additions are free.
-- **Coverage is per new line across all four packages.** A new file without tests drags the PR under 80%. Files in `sonar.coverage.exclusions` don't count either way.
-- **Ratings are about new issues.** One new bug drops reliability; one new vulnerability drops security. Don't introduce hotspot patterns (`Math.random` in anything security-adjacent, `child_process` through PATH, backtracking regexes, secret-looking strings). Path-wide suppressions live only in `sonar-project.properties` with a written justification; one-off findings are resolved on SonarCloud, never with an inline `// NOSONAR`.
-- **Check it yourself.** The `sonarqube` MCP is connected: `list_pull_requests` → `get_project_quality_gate_status` shows each condition's value; `search_duplicated_files` + `get_duplications` show what tripped duplication; `search_sonar_issues_in_projects` lists new issues. Test files are excluded from analysis — when duplication fires, the source is the problem.

-# Contributor Covenant 3.0 Code of Conduct
-
-## Our Pledge
-
-We pledge to make our community welcoming, safe, and equitable for all.
-
-We are committed to fostering an environment that respects and promotes the dignity, rights, and contributions of all
-individuals, regardless of characteristics including race, ethnicity, caste, color, age, physical characteristics,
-neurodiversity, disability, sex or gender, gender identity or expression, sexual orientation, language, philosophy or
-religion, national or social origin, socio-economic position, level of education, or other status. The same privileges
-of participation are extended to everyone who participates in good faith and in accordance with this Covenant.
-
-## Encouraged Behaviors
-
-While acknowledging differences in social norms, we all strive to meet our community's expectations for positive
-behavior. We also understand that our words and actions may be interpreted differently than we intend based on culture,
-background, or native language.
-
-With these considerations in mind, we agree to behave mindfully toward each other and act in ways that center our shared
-values, including:
-
-1. Respecting the **purpose of our community**, our activities, and our ways of gathering.
-2. Engaging **kindly and honestly** with others.
-3. Respecting **different viewpoints** and experiences.
-4. **Taking responsibility** for our actions and contributions.
-5. Gracefully giving and accepting **constructive feedback**.
-6. Committing to **repairing harm** when it occurs.
-7. Behaving in other ways that promote and sustain the **well-being of our community**.
-
-## Restricted Behaviors
-
-We agree to restrict the following behaviors in our community. Instances, threats, and promotion of these behaviors are
-violations of this Code of Conduct.
-
-1. **Harassment.** Violating explicitly expressed boundaries or engaging in unnecessary personal attention after any
-   clear request to stop.
-2. **Character attacks.** Making insulting, demeaning, or pejorative comments directed at a community member or group of
-   people.
-3. **Stereotyping or discrimination.** Characterizing anyone’s personality or behavior on the basis of immutable
-   identities or traits.
-4. **Sexualization.** Behaving in a way that would generally be considered inappropriately intimate in the context or
-   purpose of the community.
-5. **Violating confidentiality**. Sharing or acting on someone's personal or private information without their
-   permission.
-6. **Endangerment.** Causing, encouraging, or threatening violence or other harm toward any person or group.
-7. Behaving in other ways that **threaten the well-being** of our community.
-
-### Other Restrictions
-
-1. **Misleading identity.** Impersonating someone else for any reason, or pretending to be someone else to evade
-   enforcement actions.
-2. **Failing to credit sources.** Not properly crediting the sources of content you contribute.
-3. **Promotional materials**. Sharing marketing or other commercial content in a way that is outside the norms of the
-   community.
-4. **Irresponsible communication.** Failing to responsibly present content which includes, links or describes any other
-   restricted behaviors.
-
-## Reporting an Issue
-
-Tensions can occur between community members even when they are trying their best to collaborate. Not every conflict
-represents a code of conduct violation, and this Code of Conduct reinforces encouraged behaviors and norms that can help
-avoid conflicts and minimize harm.
-
-When an incident does occur, it is important to report it promptly. To report a possible violation, **send an email to
-report@liketrek.com**.
-
-Community Moderators take reports of violations seriously and will make every effort to respond in a timely manner. They
-will investigate all reports of code of conduct violations, reviewing messages, logs, and recordings, or interviewing
-witnesses and other participants. Community Moderators will keep investigation and enforcement actions as transparent as
-possible while prioritizing safety and confidentiality. In order to honor these values, enforcement actions are carried
-out in private with the involved parties, but communicating to the whole community may be part of a mutually agreed upon
-resolution.
-
-## Addressing and Repairing Harm
-
-****
-
-If an investigation by the Community Moderators finds that this Code of Conduct has been violated, the following
-enforcement ladder may be used to determine how best to repair harm, based on the incident's impact on the individuals
-involved and the community as a whole. Depending on the severity of a violation, lower rungs on the ladder may be
-skipped.
-
-1) Warning
-    1) Event: A violation involving a single incident or series of incidents.
-    2) Consequence: A private, written warning from the Community Moderators.
-    3) Repair: Examples of repair include a private written apology, acknowledgement of responsibility, and seeking
-       clarification on expectations.
-2) Temporarily Limited Activities
-    1) Event: A repeated incidence of a violation that previously resulted in a warning, or the first incidence of a
-       more serious violation.
-    2) Consequence: A private, written warning with a time-limited cooldown period designed to underscore the
-       seriousness of the situation and give the community members involved time to process the incident. The cooldown
-       period may be limited to particular communication channels or interactions with particular community members.
-    3) Repair: Examples of repair may include making an apology, using the cooldown period to reflect on actions and
-       impact, and being thoughtful about re-entering community spaces after the period is over.
-3) Temporary Suspension
-    1) Event: A pattern of repeated violation which the Community Moderators have tried to address with warnings, or a
-       single serious violation.
-    2) Consequence: A private written warning with conditions for return from suspension. In general, temporary
-       suspensions give the person being suspended time to reflect upon their behavior and possible corrective actions.
-    3) Repair: Examples of repair include respecting the spirit of the suspension, meeting the specified conditions for
-       return, and being thoughtful about how to reintegrate with the community when the suspension is lifted.
-4) Permanent Ban
-    1) Event: A pattern of repeated code of conduct violations that other steps on the ladder have failed to resolve, or
-       a violation so serious that the Community Moderators determine there is no way to keep the community safe with
-       this person as a member.
-    2) Consequence: Access to all community spaces, tools, and communication channels is removed. In general, permanent
-       bans should be rarely used, should have strong reasoning behind them, and should only be resorted to if working
-       through other remedies has failed to change the behavior.
-    3) Repair: There is no possible repair in cases of this severity.
-
-This enforcement ladder is intended as a guideline. It does not limit the ability of Community Managers to use their
-discretion and judgment, in keeping with the best interests of our community.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing
-the community in public or other spaces. Examples of representing our community include using an official email address,
-posting via an official social media account, or acting as an appointed representative at an online or offline event.
-
-## Attribution

 # MCP Integration
 
-Please refer to the [MCP wiki](https://github.com/liketrek/TREK/wiki/MCP-Overview) for more information.
+TREK includes a built-in [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) server that lets AI
+assistants — such as Claude Desktop, Cursor, or any MCP-compatible client — read and modify your trip data through a
+structured API.
+
+> **Note:** MCP is an addon that must be enabled by your TREK administrator before it becomes available.

+
+---
+
+## Setup
+
+### 1. Enable the MCP addon (admin)
+
+An administrator must first enable the MCP addon from the **Admin Panel > Addons** page. Until enabled, the `/mcp`
+endpoint returns `404` and the MCP section does not appear in user settings.
+
+### 2. Connect your MCP client
+
+#### Option A: OAuth 2.1 (recommended)
+
+MCP clients that support OAuth 2.1 (such as Claude Desktop via `mcp-remote`) authenticate automatically. No token
+management required — just provide the server URL:
+
+```json
+{
+  "mcpServers": {
+    "trek": {
+      "command": "npx",
+      "args": [
+        "mcp-remote",
+        "https://your-trek-instance.com/mcp"
+      ]
+    }
+  }
+}
+```
+
+> The path to `npx` may need to be adjusted for your system (e.g. `C:\PROGRA~1\nodejs\npx.cmd` on Windows).
+
+**What happens automatically:**
+1. The client fetches `/.well-known/oauth-protected-resource` (RFC 9728) to discover the authorization server and bind the `/mcp` endpoint.
+2. The client fetches `/.well-known/oauth-authorization-server` for the full AS metadata.
+3. The client registers itself via [Dynamic Client Registration (RFC 7591)](https://www.rfc-editor.org/rfc/rfc7591).
+4. Your browser opens TREK's consent screen, where you choose which scopes (permissions) to grant.
+5. The client receives a short-lived access token audience-bound to `/mcp` (RFC 8707) and a rotating refresh token — no re-authorization needed.
+
+> **Requirement:** The `APP_URL` environment variable must be set to your TREK instance's public URL for OAuth
+> discovery to work correctly.
+
+**For more control over scopes or to use confidential client mode**, pre-create an OAuth client in
+**Settings > Integrations > MCP > OAuth Clients** before connecting. Clients created there have a client secret
+(`trekcs_` prefix) and fixed scopes that you define up front.
+
+#### Option B: Static API Token (deprecated)
+
+> **Deprecated:** Static API tokens will stop working in a future version. Migrate to OAuth 2.1 above.
+
+1. Go to **Settings > Integrations > MCP** and create an API token.
+2. Click **Create New Token**, give it a name, and **copy the token immediately** — it is shown only once.
+3. Add it to your `claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "trek": {
+      "command": "npx",
+      "args": [
+        "mcp-remote",
+        "https://your-trek-instance.com/mcp",
+        "--header",
+        "Authorization: Bearer trek_your_token_here"
+      ]
+    }
+  }
+}
+```
+
+Static tokens grant full access to all tools and resources (no scope restrictions). Sessions authenticated with a
+static token will receive deprecation warnings in the AI client via server instructions and tool results.
+
+Each user can create up to **10 static tokens**.
+
+---
+
+## Authentication
+
+TREK's MCP server supports three authentication methods. OAuth 2.1 is the recommended path for all external clients.
+
+| Method | Token prefix | Access level | TTL | Notes |
+|--------|-------------|-------------|-----|-------|
+| **OAuth 2.1** | `trekoa_` | Scoped (per-consent) | 1 hour | Recommended. Automatically refreshed via 30-day rolling refresh tokens (`trekrf_` prefix). Replay-detected rotation — replayed tokens cascade-revoke the entire chain. |
+| **Static API token** | `trek_` | Full access | No expiry | **Deprecated.** Triggers deprecation warnings in AI clients. Will be removed in a future release. |
+| **Web session JWT** | — | Full access | Session-based | Used internally by the TREK web UI. Not intended for external clients. |
+
+All methods require the `Authorization: Bearer <token>` header (strict scheme enforcement — `Bearer` required).
+
+---
+
+## OAuth Scopes
+
+When connecting via OAuth 2.1, you grant specific scopes during the consent step. TREK registers only the MCP tools
+that match your granted scopes for that session.
+
+| Scope | Permission | Group |
+|-------|-----------|-------|
+| `trips:read` | View trips & itineraries | Trips |
+| `trips:write` | Edit trips & itineraries | Trips |
+| `trips:delete` | Delete trips (irreversible) | Trips |
+| `trips:share` | Manage share links | Trips |
+| `places:read` | View places & map data | Places |
+| `places:write` | Manage places | Places |
+| `atlas:read` | View Atlas | Atlas |
+| `atlas:write` | Manage Atlas | Atlas |
+| `packing:read` | View packing lists | Packing |
+| `packing:write` | Manage packing lists | Packing |
+| `todos:read` | View to-do lists | To-dos |
+| `todos:write` | Manage to-do lists | To-dos |
+| `budget:read` | View budget | Budget |
+| `budget:write` | Manage budget | Budget |
+| `reservations:read` | View reservations | Reservations |
+| `reservations:write` | Manage reservations | Reservations |
+| `collab:read` | View collaboration | Collaboration |
+| `collab:write` | Manage collaboration | Collaboration |
+| `notifications:read` | View notifications | Notifications |
+| `notifications:write` | Manage notifications | Notifications |
+| `vacay:read` | View vacation plans | Vacation |
+| `vacay:write` | Manage vacation plans | Vacation |
+| `geo:read` | Maps & geocoding | Geo |
+| `weather:read` | Weather forecasts | Weather |
+| `journey:read` | View journeys | Journey |
+| `journey:write` | Manage journeys | Journey |
+| `journey:share` | Manage journey share links | Journey |
+
+**Scope rules:**
+- A `:write` scope implies `:read` access for the same group (e.g. `budget:write` also grants budget read access).
+- Any `trips:*` scope (`trips:read`, `trips:write`, `trips:delete`, or `trips:share`) grants trip read access.
+- Any `journey:*` scope (`journey:read`, `journey:write`, or `journey:share`) grants journey read access.
+- `list_trips` and `get_trip_summary` are **always available** regardless of scopes — they are navigation tools.
+- Static tokens and web session JWTs have full access to all tools (equivalent to all scopes).
+- Addon-gated tools (Atlas, Collab, Vacay, Journey) require both the relevant scope **and** the addon to be enabled.

+
+## Limitations & Important Notes
+
+| Limitation                              | Details                                                                                                                                          |
+|-----------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------|
+| **Admin activation required**           | The MCP addon must be enabled by an admin before any user can access it.                                                                         |
+| **Per-user scoping**                    | Each MCP session is scoped to the authenticated user. You can only access trips you own or are a member of.                                      |
+| **No image uploads**                    | Cover images cannot be set through MCP. Use the web UI to upload trip covers.                                                                    |
+| **Reservations are created as pending** | When the AI creates a reservation, it starts with `pending` status. You must confirm it manually or ask the AI to set the status to `confirmed`. |
+| **Demo mode restrictions**              | If TREK is running in demo mode, all write operations through MCP are blocked.                                                                   |
+| **Rate limiting**                       | 300 requests per minute per user (configurable via `MCP_RATE_LIMIT`). Exceeding this returns a `429` error.                                     |
+| **Per-client rate limiting**            | Rate limits are tracked per user-client pair, so each OAuth client has its own independent rate limit window.                                    |
+| **Session limits**                      | Maximum 20 concurrent MCP sessions per user (configurable via `MCP_MAX_SESSION_PER_USER`). Sessions expire after 1 hour of inactivity.          |
+| **Token limits**                        | Maximum 10 static API tokens per user. Maximum 10 OAuth clients per user.                                                                        |
+| **Token revocation**                    | Deleting a static token or revoking an OAuth session immediately terminates all active MCP sessions for that token/client.                       |
+| **OAuth scope enforcement**             | Only tools matching your granted OAuth scopes are registered in the session. Calling an out-of-scope tool returns an error.                      |
+| **Addon toggle invalidation**           | When an admin enables or disables an addon, all active MCP sessions are invalidated and must be re-established.                                  |
+| **Real-time sync**                      | Changes made through MCP are broadcast to all connected clients in real-time via WebSocket, just like changes made through the web UI.           |
+| **Addon-gated features**                | Some resources and tools are only available when the corresponding addon (Atlas, Collab, Vacay, Journey) is enabled by an admin.                 |
+

+## Tools (read-write)
+
+TREK exposes tools organized by feature area. Use `get_trip_summary` as a starting point — it returns everything about a
+trip in a single call.
+
+### Trip Summary
+
+| Tool               | Description                                                                                                                                                                                                           |
+|--------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `get_trip_summary` | Full denormalized snapshot of a trip: metadata, members, days with assignments and notes, accommodations, budget, packing, reservations, collab notes, to-dos, and poll/message counts. Use this as your context loader. |

+### Compound Tools
+
+Compound tools collapse common multi-step workflows into a single atomic call. Each one wraps two sequential operations in a database transaction — if the second step fails, the first is rolled back automatically.
+
+> **When to use:** Only use compound tools when the place or item does not yet exist. If it already exists, call the individual tools (`assign_place_to_day`, `create_accommodation`, `set_budget_item_members`) directly.
+
+| Tool | Wraps | Description |
+|---|---|---|
+| `create_and_assign_place` | `create_place` + `assign_place_to_day` | Create a new place and immediately assign it to a specific day. Accepts all `create_place` fields (`place_notes` instead of `notes`) plus `dayId` and optional `assignment_notes`. Returns `{ place, assignment }`. |
+| `create_place_accommodation` | `create_place` + `create_accommodation` | Create a new place and immediately book it as an accommodation for a date range. Accepts all `create_place` fields (`place_notes` instead of `notes`) plus `start_day_id`, `end_day_id`, `check_in`, `check_out`, `confirmation`, and `accommodation_notes`. Also auto-creates a linked hotel reservation. Returns `{ place, accommodation }`. |
+| `create_budget_item_with_members` | `create_budget_item` + `set_budget_item_members` | Create a budget item and optionally set which members are splitting it. Accepts all `create_budget_item` fields plus an optional `userIds` array. If `userIds` is omitted or empty, behaves identically to `create_budget_item`. Returns `{ item }` with members populated. |
+
+**Scope requirements** match the underlying tools: `places:write` for `create_and_assign_place`, `trips:write` for `create_place_accommodation`, `budget:write` for `create_budget_item_with_members` (Budget addon required).

+
+Initial prompt (1st message):
+
+```
+I'd like to plan a week-long trip to Kyoto, Japan, arriving April 5 2027
+and leaving April 11 2027. It's cherry blossom season so please keep that
+in mind when picking spots.
+
+Before writing anything to TREK, do some research: look up what's worth
+visiting, figure out a logical day-by-day flow (group nearby spots together
+to avoid unnecessary travel), find a well-reviewed hotel in a central
+neighbourhood, and think about what kind of food and restaurant experiences
+are worth including.
+
+Once you have a solid plan, write the whole thing to TREK:
+- Create the trip
+- Add all the places you've researched with their real coordinates
+- Build out the daily itinerary with sensible visiting times
+- Book the hotel as a reservation and link it properly to the accommodation days
+- Add any notable restaurant reservations
+- Put together a realistic budget in EUR
+- Build a packing list suited to April in Kyoto
+- Leave a pinned collab note with practical tips (transport, etiquette, money, etc.)
+- Add a day note for each day with any important heads-up (early start, crowd
+  tips, booking requirements, etc.)
+- Mark Japan as visited in my Atlas
+
+Currency: CHF. Use get_trip_summary at the end and give me a quick recap
+of everything that was added.
+```

-### Every part of your trip. One app you own.
+<br />
 
-TREK has grown from a travel planner into a whole ecosystem for trips: plan together in real time on a live map, build hikes, tours and road trips, keep bookings and shared costs in order, pack, write the journal, lay out the photo book and hand the busy work to the built-in AI. Self-hosted, on the web, on your phone and offline.

-#### 🧭 Planning
+#### 🧭 Trip planning
 
-- **Day plans**: drag places, notes and bookings between days with undo, or drop a map marker straight onto a day
-- **Maps**: Leaflet, Mapbox GL or MapLibre GL (OpenFreeMap, no token) with clustering, photo markers, route lines and a whole-trip route overview
-- **Places**: search the TREK Places index and OpenStreetMap with no key, or Google Places and Amap with one. Descriptions, hours and photos from Wikipedia, Wikidata and Wikimedia Commons, plus a rating and a custom image per place
-- **Explore**: nearby places by category for the map view, from the TREK Places index with Overpass as fallback
-- **Routes**: auto-sort a day (nearest neighbour then 2-opt, locked stops and hotels stay put), a travel mode per leg over OSRM or Valhalla, then open the day in Google Maps or CoMaps and a place in seven navigation apps
-- **Public transport**: door-to-door itineraries over Transitous, or Google where Transitous has no data
-- **Import and export**: Google Maps and Naver Maps lists, Google Maps directions links, GPX, KML and KMZ in; GPX and an ICS feed per trip or across all trips out
-- **Weather**: 16-day forecast from Open-Meteo, no key, and the archive for dates beyond it
-- **Trip dates**: move a trip and its days re-date themselves, with the bookings along or re-anchored. Trips also copy and archive
-- **Road trip** (off by default): drives with stops, day windows and arrival times that recompute, route alternatives, hazards and EV charging with range
+- **Drag & drop planner** — organise places into day plans with reordering and cross-day moves
+- **Interactive map** — Leaflet or Mapbox GL with 3D buildings, terrain, photo markers, clustering, route visualization
+- **Place search** — Google Places (photos, ratings, hours) or OpenStreetMap (free, no API key)
+- **Place import** — shared Google Maps / Naver Maps lists, plus GPX and KML/KMZ/GeoJSON map files
+- **Day notes** — timestamped, icon-tagged notes with drag-and-drop reordering
+- **Route optimisation** — auto-sort places and export to Google Maps
+- **Weather forecasts** — 16-day via Open-Meteo (no key) + historical climate fallback
+- **Category filter** — show only matching pins on the map

-#### 🥾 Tours
+#### 🧳 Travel management
 
-- **Seven tour types**: hike, city walk, run, bike (touring, road, gravel, MTB), paddle (kayak, canoe, SUP), horse ride, and ski and winter (alpine, cross-country, touring, snowshoe, winter hike)
-- **Routing**: legs routed over Valhalla with shaping points, hand-drawn legs, route variants, round hikes of a wished length and trip places as stops, all with undo
-- **Hikes**: routed within a maximum SAC grade (T1 to T6), the trail grades along the way, and via ferratas on the map
-- **Terrain**: elevation profile, ascent and descent, and a 3D terrain map with grade colouring and a flyover, no token needed. Topo, hiking, cycling and satellite bases with sea marks and ski pistes as overlays
-- **Multi-day tours**: one route cut into stages and spread across the trip's days
-- **Along the way**: viewpoints, huts, water, food and more within a corridor of the route, inserted as a stop with the detour it adds
-- **Ski, paddle and city walks**: a piste router by difficulty and lift type; a water router with portages, locks and a wind forecast; city walks with stays, opening hours and transit between stops
-- **Plan against reality**: link a recorded GPX to a planned day and compare distance, ascent and time. Import trails from a wanderer instance, save tours to a collection and take them into another trip
+- **Reservations** — flights, accommodations, restaurants with status, confirmation numbers, files; import from booking confirmation emails and PDFs ([KDE Itinerary](https://invent.kde.org/pim/kitinerary))
+- **Costs** — track and split trip expenses (Splitwise-style): per-person / per-day breakdowns, settle-up, multi-currency
+- **Packing lists** — categories, templates, user assignment, progress tracking
+- **Bag tracking** — optional weight tracking with iOS-style distribution
+- **Document manager** — attach docs, tickets, PDFs to trips / places / reservations (≤ 50 MB each)
+- **PDF export** — full trip plan as PDF with cover page, images, notes

-#### 🧳 Bookings and money
-
-- **Reservations**: 18 booking types with status, confirmation code, travellers and attached files
-- **Flights and trains**: several legs with stopovers and endpoint timezones, against 4,045 bundled airports so local times resolve without a key
-- **Accommodation**: a stay spans a range of nights with a check-in window
-- **Booking import**: EML, PDF, PKPass, HTML, TXT and photos of confirmations, through [KItinerary](https://invent.kde.org/pim/kitinerary) or an AI model, with a review step before anything is saved. Prices become linked costs
-- **AirTrail** (off by default): import flights from a self-hosted AirTrail instance and keep them in sync
-- **Costs**: split in integer cents with equal or custom shares, several payers, settle-up suggestions, a per-person summary, a settlement log and CSV export. A receipt photo can fill in an expense
-- **Currencies**: one per expense with the rate frozen at entry, from Frankfurter with no key
-- **Packing lists and to-dos**: categories, templates, assignees and visibility tiers; bags with weights as an admin switch; to-dos with due dates, priorities and reminders
-- **Files**: attach to a trip, place, day or booking, 50 MB each and 500 MB for video, with trash and restore
-- **PDF export**: cover, place photos, day notes, bookings and costs, with an optional page break per day

 #### 👥 Collaboration
 
-- **Real-time sync** (WebSocket): edits land live for everyone who has the trip open
-- **Members**: add by email or username, hand over ownership, or add guests who have no login at all
-- **Permissions**: an admin maps each of 17 trip actions to admin, trip owner, trip member or everybody
-- **Invites**: one reusable link per trip with an optional expiry, and admin signup invites that drop a new account straight into a trip

-- **Collab**: group chat with replies, reactions and link previews, shared notes, links, polls and a What's Next list, each one its own switch
-- **Notifications**: an inbox grouped by day with answers right from the notification, and a per-user matrix of events against in-app, email, webhook, ntfy, Web Push and plugin channels
+- **Real-time sync** — WebSocket. Changes appear instantly across all connected users
+- **Multi-user trips** — invite members with role-based access
+- **Invite links** — one-time or reusable links with expiry

-#### 🤖 AI assistant and MCP
+#### ⚙️ Admin & customisation
 
-- **AI assistant** (off by default): a chat that plans with you in a trip, across all your trips, in a journal and in Studio, and works with tours, costs, bookings, packing, Vacay and the Atlas
-- **Your own model**: an API key for Anthropic, OpenAI, Gemini or OpenRouter, a ChatGPT plan, or any OpenAI-compatible endpoint, set for the instance or per user
-- **You stay in charge**: reads run at once, every change waits as a card to apply or discard and can be undone for 15 minutes. Nothing leaves before you agree to the provider, and a file's text only with your consent
-- **Attachments**: drop a booking confirmation, a GPX file or a photo into the chat, and the assistant offers what to do with it
-- **MCP server** (off by default): OAuth 2.1 with mandatory PKCE and dynamic client registration, 410 tools, 30 resources and 4 prompts, 35 scopes in 17 groups ticked on the consent screen, and every call in the audit log
-- **Addon-aware**: twelve addon gates decide which tools a session sees, and flipping one re-registers live sessions

-<td width="50%" valign="top">
-
-#### 🧩 Plugins
-
-- **Third-party plugins**: install from the TREK registry or sideload a zip, with their own pages under `/plugins/<id>`
-- **Sandboxed**: one child process per plugin, 66 grantable permissions, an admin-edited outbound host allowlist, memory and call caps
-- **Trust**: registry downloads are pinned by sha256 and checked against the author's minisign key, a sideloaded zip is marked unverified, and `TREK_PLUGINS_ENABLED=false` turns the whole system off
-- **Extension points**: map layers, place details, day schedules, PDF sections, Atlas layers, journal rows, trip warnings, search and photo providers, route profiles, notification channels and MCP tools
-- **SDK**: [`trek-plugin-sdk`](https://www.npmjs.com/package/trek-plugin-sdk) with a CLI to create, validate, run against real data, sign and publish

-#### 📱 Mobile and offline
-
-- **Apps**: TREK Travel Planner for iPhone, iPad and Android connects to any TREK server, and the browser installs TREK as a standalone app with a themed status bar too
-- **Phone layouts**: their own screens for every part of the app, with a bottom bar and dashboard widgets the user orders
-- **Offline reads**: the app shell is precached and trips, places, tours, files and nearby places live in a per-user IndexedDB store, so a trip opens with no network
-- **Offline writes**: changes queue and replay with an `X-Idempotency-Key`, and a stale edit waits for a keep-mine or keep-theirs choice
-- **Offline maps**: raster and vector tiles of a trip downloaded ahead, and a switch that takes the whole app offline on purpose

-#### ⚙️ Admin, accounts and security
-
-- **Sign-in**: password, OIDC and passkeys each switch on and off on their own, `OIDC_ONLY` leaves SSO as the only way in, and an OIDC claim can grant admin
-- **SSO and 2FA**: one OIDC provider by discovery with PKCE (Authentik, Keycloak, Google and the like), TOTP with backup codes that an admin can require, and passkeys that count as the second factor
-- **Sessions**: every sign-in is a session you can see and end, one by one or all others at once
-- **Hardening**: rate limits on sign-in, reset and 2FA, a password policy, secrets encrypted at rest and masked on read, and an SSRF guard on every URL you configure
-- **Admin panel**: users and the permission matrix, defaults for new users, categories and templates, addons, plugins, storage, notifications, MCP tokens, backups, audit log and releases
-- **Backups and storage**: scheduled backups with retention that restore their own secrets, and local or S3-compatible storage per content category with replicas
-- **Appearance**: light, dark or follow the OS, seven colour schemes plus a custom accent, transparency, density, reduced motion and text size
-- **28 languages**: en, de, es, fr, it, nl, hu, ru, zh, zh-TW, pl, cs, ar (right to left), he (right to left), br, id, tr, ja, ko, uk, gr, sv, vi, ca, az, et, sk, th
-- **Help center**: a ? in the top bar with 381 step-by-step guides with screenshots, searched together with the wiki that ships in the image
+- **Dashboard views** — card grid or compact list · **Dark mode** — full theme with matching status bar
+- **20 languages** — EN, DE, ES, FR, IT, NL, HU, RU, ZH, ZH-TW, PL, CS, AR (RTL), BR, ID, TR, JA, KO, UK, GR
+- **Admin panel** — users, invites, packing templates, categories, addons, API keys, backups, GitHub history
+- **Notifications** — per-user preferences across email (SMTP), webhook, ntfy, and an in-app notification center
+- **Auto-backups** — scheduled with configurable retention · **Units** — °C/°F, 12h/24h, map tile sources, default coordinates

-## AI usage
-
-We use LLM-assisted coding tools across parts of this codebase. Nothing ships that a
-maintainer has not read and understood: every change goes through a pull request, is
-reviewed and tested, and has a human who can answer for it. "The AI wrote that" is not
-an answer any of us would accept from ourselves.
-
-See [**How we use AI in TREK**](https://github.com/liketrek/TREK/discussions/1851) for
-the details.

-
-`COOKIE_SECURE=false` is only for trying TREK over plain HTTP: without it the browser drops the session cookie and the login does not stick. Once TREK sits behind HTTPS (see [Reverse Proxy](#reverse-proxy)), remove it.
-
-> [!TIP]
-> **No server yet?** TREK's own public services run on [**dataforest cloud**](https://cloud.dataforest.net/en?mtm_campaign=trek), our infrastructure sponsor. A small seed is plenty for a TREK instance and is ready within a minute.

 ## Updating
 
-See [Updating](https://github.com/liketrek/TREK/wiki/Updating) — Docker Compose,
-Docker run, Helm, Portainer, Unraid and Proxmox, plus the encryption-key note.
+**Docker Compose:**
 
-<br />
+```bash
+docker compose pull && docker compose up -d
+```
+
+**Docker run** — reuse the original volume paths:
+
+```bash
+docker pull mauriceboe/trek
+docker rm -f trek
+docker run -d --name trek -p 3000:3000 -v ./data:/app/data -v ./uploads:/app/uploads --restart unless-stopped mauriceboe/trek
+```
+
+> Not sure which paths you used? `docker inspect trek --format '{{json .Mounts}}'` before removing the container.
+
+Your data stays in the mounted `data` and `uploads` volumes — updates never touch it.
+
+> [!IMPORTANT]
+> Mount **only** the data and uploads directories — `-v ./data:/app/data -v ./uploads:/app/uploads`. **Never mount a volume at `/app`.** Doing so hides the application code shipped in the image and the container fails to start with `Cannot find module 'tsconfig-paths/register'`. If you previously mounted `/app`, switch to the two mounts above; your data in `data/` and `uploads/` is preserved.
+
+<h3>Rotating the Encryption Key</h3>
+
+If you need to rotate `ENCRYPTION_KEY` (e.g. upgrading from a version that derived encryption from `JWT_SECRET`):
+
+```bash
+docker exec -it trek node --import tsx scripts/migrate-encryption.ts
+```
+
+The script creates a timestamped DB backup before making changes and prompts for old + new keys (input is not echoed).
 
 <h2 id="reverse-proxy">Reverse Proxy</h2>
 
 For production, put TREK behind a TLS-terminating reverse proxy. TREK uses WebSockets for real-time sync, so the proxy **must** support WebSocket upgrades on `/ws`.
 
-If you use the MCP addon, the proxy must also pass the `Mcp-Session-Id` header through in both directions on `/mcp` — Nginx and Caddy do this by default, but a proxy that strips it makes every tool call open a new session instead of reusing one. See the [Reverse Proxy wiki page](https://github.com/liketrek/TREK/wiki/Reverse-Proxy) for details.

+<details>
+<summary><b>Full reference</b></summary>
+
+<br />
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| **Core** | | |
+| `PORT` | Server port | `3000` |
+| `NODE_ENV` | Environment (`production` / `development`) | `production` |
+| `ENCRYPTION_KEY` | At-rest encryption key for stored secrets (API keys, MFA, SMTP, OIDC). Recommended: generate with `openssl rand -hex 32`. If unset, falls back to `data/.jwt_secret` (existing installs) or auto-generates a key (fresh installs). | Auto |
+| `TZ` | Timezone for logs, reminders and cron jobs (e.g. `Europe/Berlin`) | `UTC` |
+| `LOG_LEVEL` | `info` = concise user actions, `debug` = verbose details | `info` |
+| `DEFAULT_LANGUAGE` | Default language on the login page for users with no saved preference. Browser/OS language is auto-detected first; this is the fallback. Supported: `de`, `en`, `es`, `fr`, `hu`, `nl`, `br`, `cs`, `pl`, `ru`, `zh`, `zh-TW`, `it`, `ar`, `id`, `tr`, `ja`, `ko`, `uk`, `gr` | `en` |
+| `ALLOWED_ORIGINS` | Comma-separated origins for CORS and email links | same-origin |
+| `FORCE_HTTPS` | Optional. When `true`: 301-redirects HTTP to HTTPS, sends HSTS, adds CSP `upgrade-insecure-requests`, forces the session cookie `secure` flag. Useful behind a TLS-terminating reverse proxy. Requires `TRUST_PROXY`. | `false` |
+| `HSTS_INCLUDE_SUBDOMAINS` | When `true`: adds the `includeSubDomains` directive to the HSTS header, extending HTTPS enforcement to all subdomains. Only effective when HSTS is active (`FORCE_HTTPS=true` or `NODE_ENV=production`). Leave `false` if you run other services on sibling subdomains over plain HTTP. | `false` |
+| `COOKIE_SECURE` | Controls the `secure` flag on the `trek_session` cookie. Auto-derived: on when `NODE_ENV=production` or `FORCE_HTTPS=true`. Escape hatch: set `false` to allow session cookies over plain HTTP. Not recommended in production. | auto |
+| `SESSION_DURATION` | How long a login session stays valid when **"Remember me" is unchecked** (the default): sets the `trek_session` JWT `exp` and issues a browser-session cookie (cleared when the browser closes). Accepts `ms`-style strings: `1h`, `12h`, `7d`, `30d`, `90d`. Invalid values warn at startup and fall back to the default. | `24h` |
+| `SESSION_DURATION_REMEMBER` | Session length when **"Remember me" is ticked** at login: a longer-lived JWT plus a persistent `trek_session` cookie that survives browser restarts. Same format and startup-fallback behaviour as `SESSION_DURATION`. | `30d` |
+| `TRUST_PROXY` | Number of trusted reverse proxies. Tells the server to read client IP from `X-Forwarded-For` and protocol from `X-Forwarded-Proto`. Defaults to `1` in production; off in dev unless set. | `1` |
+| `ALLOW_INTERNAL_NETWORK` | Allow outbound requests to private/RFC-1918 IPs (e.g. Immich on your LAN). Loopback and link-local addresses remain blocked. | `false` |
+| `APP_URL` | Public base URL of this instance (e.g. `https://trek.example.com`). Required when OIDC is enabled; used as base for email notification links. | — |
+| **OIDC / SSO** | | |
+| `OIDC_ISSUER` | OpenID Connect provider URL | — |
+| `OIDC_CLIENT_ID` | OIDC client ID | — |
+| `OIDC_CLIENT_SECRET` | OIDC client secret | — |
+| `OIDC_DISPLAY_NAME` | Label shown on the SSO login button | `SSO` |
+| `OIDC_ONLY` | Force SSO-only mode: disables password login + registration, regardless of Admin > Settings. The first SSO login becomes admin. | `false` |
+| `OIDC_ADMIN_CLAIM` | OIDC claim used to identify admin users | — |
+| `OIDC_ADMIN_VALUE` | Value of the OIDC claim that grants admin role | — |
+| `OIDC_SCOPE` | Space-separated OIDC scopes. **Fully replaces** the default — always include `openid email profile`. | `openid email profile` |
+| `OIDC_DISCOVERY_URL` | Override the auto-constructed OIDC discovery endpoint (e.g. Authentik: `.../application/o/trek/.well-known/openid-configuration`) | — |
+| **Initial setup** | | |
+| `ADMIN_EMAIL` | Email for the first admin on initial boot. Must be set together with `ADMIN_PASSWORD`. If either is omitted a random password is printed to the server log. No effect once a user exists. | `admin@trek.local` |
+| `ADMIN_PASSWORD` | Password for the first admin on initial boot. Pairs with `ADMIN_EMAIL`. | random |
+| **Other** | | |
+| `DEMO_MODE` | Enable demo mode (hourly data resets) | `false` |
+| `MCP_RATE_LIMIT` | Max MCP API requests per user per minute | `300` |
+| `MCP_MAX_SESSION_PER_USER` | Max concurrent MCP sessions per user | `20` |

 ## Usage
 
 Or install directly from the local chart:
 
 ```sh
-helm install trek ./charts/trek \
+helm install trek ./chart \
   --set ingress.enabled=true \
   --set ingress.hosts[0].host=yourdomain.com
 ```
@@ -47,14 +44,9 @@ See `values.yaml` for more options.
 - With `persistence.enabled: false`, the data and uploads volumes use an `emptyDir` — storage is ephemeral and lost on pod restart. Intended for testing only.
 - `JWT_SECRET` is managed entirely by the server — auto-generated into the data PVC on first start and rotatable via the admin panel (Settings → Danger Zone). No Helm configuration needed.
 - `ENCRYPTION_KEY` encrypts stored secrets (API keys, MFA, SMTP, OIDC) at rest. Recommended: set via `secretEnv.ENCRYPTION_KEY` or `existingSecret`. If left empty, the server falls back automatically: existing installs use `data/.jwt_secret` (no action needed on upgrade); fresh installs auto-generate a key persisted to the data PVC.
-- Liveness and readiness probes are configurable under `probes`. Overrides are merged over the defaults, so `--set probes.liveness.initialDelaySeconds=60` keeps the `httpGet` handler. When switching to `exec` or `tcpSocket`, clear `httpGet` in the same override. Set `probes.liveness: null` to remove a probe.
-- If exposing TREK through an Ingress or HTTPRoute, set `env.ALLOWED_ORIGINS` and `env.APP_URL` to the public URL. The chart does not sync these automatically.
+- If using ingress, you must manually keep `env.ALLOWED_ORIGINS` and `ingress.hosts` in sync to ensure CORS works correctly. The chart does not sync these automatically.
 - Set `env.ALLOW_INTERNAL_NETWORK: "true"` if Immich or other integrated services are hosted on a private/RFC-1918 address (e.g. a pod on the same cluster or a NAS on your LAN). Loopback (`127.x`) and link-local/metadata addresses (`169.254.x`) remain blocked regardless.
-- Set `env.ALLOW_LINK_LOCAL_IPS` to a single link-local address (e.g. `"169.254.1.2"`) only when a service TREK needs sits behind one, such as a host gateway. Cloud metadata addresses (`169.254.169.x`, `169.254.170.x`) cannot be listed.
 - `FORCE_HTTPS` is optional. Set `env.FORCE_HTTPS: "true"` only when ingress (or another proxy) terminates TLS. It enables HTTPS redirects, HSTS, CSP `upgrade-insecure-requests`, and forces the session cookie `secure` flag. Requires `TRUST_PROXY` to be set.
 - Set `env.TRUST_PROXY: "1"` (or the number of proxy hops) when running behind ingress or a load balancer. Required for `FORCE_HTTPS` to detect the forwarded protocol correctly. In production it defaults to `1` automatically.
 - `COOKIE_SECURE` is auto-derived (on when `NODE_ENV=production` or `FORCE_HTTPS=true`). Set `env.COOKIE_SECURE: "false"` only during local testing without TLS. **Not recommended for production.**
-- Web Push needs no chart settings: TREK generates its key pair on first start and keeps it in the database on the data PVC. To bring your own pair, set `env.VAPID_PUBLIC_KEY` and `secretEnv.VAPID_PRIVATE_KEY` together (and optionally `env.VAPID_SUBJECT`); changing the pair later means every device has to turn push on again.
 - Set `env.OIDC_DISCOVERY_URL` to override the auto-constructed OIDC discovery endpoint. Required for providers (e.g. Authentik) that expose it at a non-standard path.
-- `podSecurityContext` defaults to `fsGroup: 1000` with `fsGroupChangePolicy: OnRootMismatch`, and `securityContext` (the container's) is empty. The container then starts as root, hands `/app/data` and `/app/uploads` to `node` (uid 1000) if the directory or anything directly inside it is not owned by `node` yet, and drops to `node`. Deeper files are not checked. Only the owning user is changed (plus a `root` group), so a different `fsGroup` stays in place. A volume that refuses `chown` (NFS with `root_squash`) logs a warning instead; set `runAsUser: 1000` then. To run as `node` from the start, for example under the `restricted` Pod Security Standard, set `podSecurityContext.runAsUser: 1000` and `runAsGroup: 1000`; the image then skips that step and the privilege drop. See the example in `values.yaml`.
-- Use `extraVolumes` and `extraVolumeMounts` to add your own volumes to the pod. To give the booking import more KItinerary extractors, mount a ConfigMap at `/usr/local/share/kitinerary/extractors`, with one `.json` and one `.js` key for each extractor; see the example in `values.yaml`.

-Every baseline ratchet above also fails on an entry that allows more than the tree holds: a count above what its file or rule has now, or a file that is gone. Run the check with `--update` in the change that made it smaller, so a fixed file cannot grow back to its old entry and a new file at a deleted path does not inherit one.
-
-Single test: `npx vitest run src/store/slices/budgetSlice.test.ts`, or `npx vitest run -t "optimistically adds the place"`.
-
-The dev server needs the API on **:3001** — run `npm run dev` at the repo root to start both.
-
-## Page pattern (enforced — `lint:pages` fails otherwise)
-
-Every `src/pages/*Page.tsx` is a thin **wiring container**; all state/effects/handlers live in a co-located **`use<Page>()` hook** under `src/pages/<page>/`. The page body must **not** call React state/effect/memo/ref hooks — only context hooks like `useTranslation()`. An optional `<page>Model.ts` holds pure, React-free types and helpers. Full spec in `src/pages/PATTERN.md`. When extracting, keep the rendered JSX byte-identical — it is a refactor of where logic lives.
-
-## Data flow — offline-first
-
-The layering is **component → feature hook → store/slice → `repo/` → `api/` | Dexie**, and writes go through a mutation queue:
-
-- **`src/store/`** — Zustand. `tripStore.ts` is composed from slices in `store/slices/`; `slices/remoteEventHandler.ts` applies inbound WebSocket events to local state.
-- **`src/repo/`** — per-entity repositories mediating between the network and the offline cache: online, call REST and upsert into Dexie; offline, read Dexie. Always go through a repo for trip data.
-- **`src/api/client.ts`** — the single Axios instance, typed from `@trek/shared`. New API surface goes in a per-domain `api/<domain>.ts`, not the god module.
-- **`src/db/offlineDb.ts`** — the Dexie schema. Database and table names are the on-device contract — renaming one orphans every user's cache. Versions are append-only: a new `this.version(N)` adds its stores to `HISTORY` and a case to `UPGRADE_CASES` in `tests/unit/db/offlineDb.upgrade.test.ts`, which opens the previous version with seeded rows in fake-indexeddb and upgrades it to the current one; a guard there fails on a declared version without both. Never edit a shipped version's stores or `upgrade()`.
-- **`src/sync/`**: in `mutationQueue.ts`, offline writes do an optimistic Dexie write (temporary **negative id** for creates), then `flush()` replays REST on reconnect with the mutation's UUID as the **`X-Idempotency-Key`** header (matching the server interceptor) and reconciles the row. Writes to one entity keep their order: a write parked as `failed` or `conflict` holds back the later writes to the same `resource` + entity id until the user retries, resolves or discards it, and only that action deletes a parked row (trip eviction never does). Every row `enqueue()` writes carries `schemaVersion` (`MUTATION_SCHEMA_VERSION` in `offlineDb.ts`) and `buildVersion`; bump the constant when a row's fields or the way the replay reads them change incompatibly. A flush replays its own format and older ones (an unstamped row is format 1) and skips a row from a newer format without sending, marking or dropping it, holding back the later writes to its entity, so a tab still on an older bundle never replays a shape it does not know. The guard exists only from the release that introduced `schemaVersion` on; a bundle older than that replays every row, so the first bump of `MUTATION_SCHEMA_VERSION` must not ship while a rollback target older than the guard is still in play. A skipped row stays `pending` with no retry or discard path, so on a rolled-back install it holds its entity until the user clears the cache. Repos whose writes carry no version token (visits, day clears, tours, driving settings) ask `mutationQueue.mustQueue()` before an online write and queue it while an older write to the entity is still queued, so a retried write cannot land over a newer one made here online; places and packing items send `X-Base-Updated-At`, so the server refuses the stale replay with a 409 instead. `flush()` takes the Web Lock `trek-mutation-flush:<db name>` so only one tab replays at a time; a tab that finds it taken waits for it, and a `flush()` called while this tab's flush runs or waits for the lock gets that same flush back (with one more pass asked for), so `flush()` never resolves while a tab is still replaying and a re-seed chained onto it cannot lay older server rows over those writes (the in-tab flush alone where the API is missing). The rest of the directory drives reconnection sync, the auth gate that stops background loops before logout swaps the DB, offline preferences, and map pre-download (raster and vector prefetchers).
-
-## Rules for new code
-
-The offline core is flagship work surrounded by a periphery that ignores it. New code extends the core's discipline, not the periphery's shortcuts:
-
-- **One data path, no layer skips.** Never import `api/client` (or raw fetch/axios) from a component or modal, and especially never *write* from one. `lint:offline` enforces it: a file under `components/`, `mobile/`, `pages/` or `hooks/` may not import anything from `src/api/` except types. The long tail that already does is listed in `scripts/offline-baseline.json`; the list only shrinks (a file that stops leaves it via `--update`) and is debt, not precedent. A domain that is online-only on purpose (admin, auth) still puts its calls in a store or repo, not in the view.
-- **Offline-first is the product promise.** New domains get a repo with read-through and offline writes (temp id → optimistic Dexie write → idempotent queue entry). If a domain is deliberately online-only, say so explicitly.
-- **Imports go downwards** (`lint:layers`, rules in `scripts/lib/layers.mjs`). A component never imports `pages/` or `mobile/`, a shared hook no view, and stores, repos, sync, api, db and the helpers no view at all; a file directly in `src/` is the layer of its name, so `src/types.ts` follows the `types/` rules. A model or helper both sides need moves down (`utils/`, `hooks/`, `types/`); the counts in `scripts/layers-baseline.json` are debt, not precedent.
-- **No god components or god hooks.** The page pattern is a floor, not a ceiling. Decompose hooks by concern, split renders into memoizable sections, and don't pass huge prop bags with inline-arrow callbacks.
-- **Prefer React 19 idioms**: `useOptimistic`, `useActionState`/`useFormStatus`, `use()` + Suspense, `useSyncExternalStore` for external subscriptions (`hooks/useNetworkMode` is the reference).
-- **Optimistic writes must reconcile** — rollback + user-visible toast on failure. No `.catch(() => {})`, no bare `catch {}`.
-- **WS remote-event handling must match local slice reducers field-for-field.** Divergence is silent, cross-user data loss.
-- **Subscribe with selectors** (`useShallow` for multi-field reads); never whole-store subscriptions; `getState()` for imperative access in effects.
-- **Connectivity**: `isEffectivelyOffline()` is the single source of truth — never read `navigator.onLine` in feature code.
-- **Rendering security**: never interpolate user content into HTML strings (map popups included — build via DOM + `textContent`, or `escapeHtml` from `@trek/shared`); untrusted markdown gets `rehype-sanitize`; never `rehype-raw` near it.
-- **No `window` event buses or global mutable `window` state.** No `any` at boundaries: WS payloads and map renderer props get real types.
-- **Hygiene**: error boundaries around new shells/routes (`components/shared/ErrorBoundary.tsx`); every async `.then(setState)` needs a cancelled flag or `AbortController`; no routine `eslint-disable exhaustive-deps` (a missing dep has already shipped wrong money on screen); no sequential-await N+1 fetch loops; search for an existing utility before writing a duplicate.
-- **Theming**: use the semantic Tailwind tokens defined in `tailwind.config.js` (`bg-surface*`, `text-content*`, `border-edge*`, `bg-accent*`, status colors) — no palette classes, hex literals, arbitrary-value color classes, or invented CSS vars. Only `applyAppearance()` in `src/theme/` mutates `<html>` styling (see `src/theme/README.md`). `theme:lint` counts literals, `bg-[#...]`-style and palette classes, raw `text-sm`- and `text-[13px]`-style sizes, z-index literals and `dark_mode` reads per file against `scripts/theme-baseline.json`.
-
-## Big-picture pieces
-
-- **Maps** (`src/components/Map/`): two interchangeable renderers — Leaflet and Mapbox/MapLibre GL — chosen at runtime by `MapViewAuto.tsx`. Keep both in sync when changing map features, and keep `mapbox-gl` and `maplibre-gl` in separate chunks (`check:gl-split`). The raster prefetcher fetches tiles `no-cors` so custom tile providers without CORS headers keep working; the vector prefetcher deliberately uses `cors` because it has to read the responses — don't "align" one with the other.
-- **i18n** (`src/i18n/TranslationContext.tsx`): `en` is bundled; every other locale is a dynamic `import('@trek/shared/i18n/<locale>')` so Vite emits one chunk per locale. Strings live in `shared/`, never here. `t()` returns an unknown key unchanged, so `lint:i18n-keys` (`scripts/i18n-keys.mjs`) resolves every literal key in `t()`, `tHtml()`, `tr()`, `<TransHtml html>`, `translateApiError` and `*Key` props against `shared/src/i18n/en`; a template whose interpolations only choose between string literals is expanded and each branch checked as a key; any other template key is read with each interpolation as one key segment and passes by itself only when it reaches between 1 and `MAX_IMPLICIT_MATCHES` (30) en keys; a wider one, or one with no fixed dotted prefix, needs a `DYNAMIC_ALLOWED` entry keyed by file and template that says what bounds the value, and an entry the check no longer needs fails. Pass counts as numbers, and let a plural group pick the wording instead of switching keys on the count.
-- **Mobile shell** (`src/mobile/`): below the phone breakpoint (`useIsPhone`) `App.tsx` wraps routes in `MobileShell` and the `M*` screens under `mobile/screens/` take over. A UI change to a domain with an `M*` twin usually needs both, and the logic change goes into the shared hook (see "Desktop and phone views" below).
-- **Plugins UI** (`src/components/Plugins/`): third-party surfaces render only inside the sandboxed `PluginFrame` iframe (postMessage bridge, live theme-token sync). Host-rendered contribution points (widgets, schedule rows, map layers, planner columns/actions) render server-normalized primitives only — plugin markup never runs inline. Authoring is covered by the `trek-plugin-dev` skill.
-- **Managed installs** (`src/managed/index.tsx`): the attachment point for screens that only exist on a centrally administered install. Empty here by design — an operator replaces it at build time. Don't put features there.
-

-
-Most features have a desktop view (`components/`, `pages/`) and a phone view (`mobile/screens/`). They share one hook or model per feature that holds the logic (state, effects, loading, handlers, validation, derived values, store and repo calls); each view keeps only its own markup, layout and dialogs or sheets. `useInstanceSettings` and `useRangeBypass` under `components/Admin/` show the shape. `scripts/feature-pairs.json` lists every pair with its hooks.
-
-- **Changing a feature:** change the shared hook, not one view. A behaviour that really differs between the two views is a parameter of the hook, so both stay visible in one place and its test covers both.
-- **A new feature with both views:** write the hook first under `components/<Feature>/` (or `hooks/`/`utils/` when it is not bound to one feature; a page's own logic stays in its `use<Page>` hook and models in `pages/<page>/`, which the phone shell imports too), give it its own test, build both views on it and add the pair to `scripts/feature-pairs.json`.
-- **A new phone screen:** list it in `scripts/feature-pairs.json`, as a view of the pair whose hook it runs on or under `mobileOnly` with the reason it has no twin. A file under `mobile/screens/` that is in neither fails `lint:pairs`.
-
-Two CI gates hold this: `lint:pairs` fails when a listed view stops importing its pair's hook or a phone screen is not listed, and `lint:dup` holds the lines inside copied blocks to `scripts/dup-baseline.json`, so a copy that looks alike fails too. SonarCloud allows **≤ 3% duplicated lines on the PR's new code**, so the same lines added to both views fail a PR by themselves. Full gate rules in the root `CLAUDE.md`.
-
-## Tests
-
-vitest with `@vitejs/plugin-react`, a custom jsdom environment (`tests/environment/`), `forks` pool. Tests live in `tests/{unit,integration}/` and co-located as `src/**/*.test.{ts,tsx}`. `msw` mocks HTTP, `fake-indexeddb` backs Dexie. Page tests render JSX against a mocked hook; hook/slice logic is tested in isolation (see `store/slices/budgetSlice.test.ts`).

-                 launchMode is singleTask above, so a link delivers into the
-                 running task via onNewIntent rather than starting a second copy
-                 of the app on top of the first.
-
-                 This is the return path for SSO and passkey sign-in: TrekShell
-                 opens the server's login page in a Custom Tab, and after the
-                 hand-off it redirects to com.liketrek.trek://auth?code=…, which
-                 lands here and in TrekShellPlugin.handleOnNewIntent.
-
-                 Not an App Link (autoVerify + https). App Links are verified
-                 against a specific domain via assetlinks.json, and TREK is
-                 self-hosted — there is no single domain to verify against. A
-                 custom scheme is the only form that works for every user's
-                 server. -->
