Maurice 9dd0a851ca fix: eleven reported bugs across atlas, budget, collections, journey, vacay and the LLM settings (#1923)
* fix(mcp): accept per-leg times on create_transport and update_transport

metadata was pinned to Record<string, string>, so a legs array could not get
through and a multi-leg flight built over MCP lost every intermediate time. The
booking ended up with correct endpoints and no legs, which every reader then
treats as a single segment.

legs is now a real, typed parameter with its contract in @trek/shared, shaped
exactly the way the planner form and the importers write metadata.legs. The
folding checks what the readers depend on: one leg fewer than endpoints (the
AirTrail dedupe builds its signatures on that), day ids that belong to the trip,
airport codes that agree with their endpoint, and the times, where a stopover
endpoint carries the departure and the last one the arrival.

metadata keeps its type and its replace semantics. Segments smuggled through
metadata.legs as a JSON string used to be stored and then ignored by everything
that read them; they are refused now and point at the legs parameter instead.

Closes #1914

* fix(atlas): refuse a bucket list entry that is already on the list

Nothing gave a bucket entry an identity, so the same country could be added as
often as it was clicked. A wish is now identified by name, country, target date
and, where it has them, coordinates. A different target date is a different wish
and still lands, which is what the report asked for; two real places sharing a
name stay separate because their coordinates differ.

Empty string and NULL are normalised on both sides of the comparison, otherwise
the dateless case, which is the one that was reported, would slip through.

Deliberately no unique index and no migration. better-sqlite3 is synchronous and
the server is a single process, so the race an index would guard against cannot
happen here, and an index would have needed a destructive dedupe of existing
rows first.

create_bucket_list_item had no target_date parameter at all, so over MCP the
allowed "same place, other date" case was unreachable. It takes one now. The
plugin RPC reports the duplicate as bad params instead of letting it surface as
an internal error.

Closes #1898

* fix(settings): keep a free-form LLM endpoint in admin hands

Any account could name the address the server calls, and the guard in front of
it deliberately allows loopback and LAN so a self-hosted Ollama works. That is a
reasonable trade for whoever runs the instance, because the network is theirs. It
is not one for an arbitrary account, which could aim a request from inside that
network at a target only it chose and read how the target answered.

A free base URL, and the local provider that is one by another name, now come
only from an admin controlled source: the addon config, the instance-wide
defaults, or an admin's own settings. OpenAI and Anthropic stay available to
everyone, because they go to a fixed address with the user's own key.

The resolver is where this is enforced, since it is the single point both the
booking import and the plugin host pass through, and the only one that also
covers values already sitting in the database. The write path refuses as well,
so nothing is stored that would never be read.

The hint text promised something users no longer have, so it changed with it.

Closes #1772

* fix(calendar): span a date-only booking to its end date

A DATE event without DTEND is exactly one day per RFC 5545, so a multi-day
booking that carries an end date still collapsed onto its first day. It gets an
exclusive DTEND now, built the same way the stay branch already builds one. A
booking without an end date serialises byte for byte as before.

While in here: the stays query joins reservations on the accommodation, and two
bookings pointed at the same stay fanned it out into two events sharing one UID.
Duplicate UIDs in a feed are undefined behaviour and calendar clients pick one at
random.

The same "at most one booking per stay" assumption sat in the accommodations
service, where it was worse than cosmetic: accommodation_id carries no foreign
key, so deleting a stay took only the first booking and left the second pointing
at something that no longer existed. Both the sync and the delete walk all of
them now. The callers keep reading linkedReservationId; the list is additional.

Refs #1869

* fix(vacay): say that the region is required, because it is

The placeholder called the region optional while the add button stayed disabled
until one was picked. The wording predates multiple calendars per plan, which is
what introduced the gate. Only the value of the existing key changed, in all
locales, so the key set stays identical.

Two things the same screen got wrong were in the way of a clean answer:

The button was clickable while the region list was still loading, which put the
user in exactly the state the wording describes, and it is the state the report
was filed from. It waits for the list now.

Changing the country on an existing calendar kept the previous country's regions
on screen, so a German region could be picked for the Netherlands. The list is
cleared with the country, which only works in combination with the loading gate:
without it, the empty list would happen to enable the button instead.

Closes #1813

* fix(collections): let a saved place's address be corrected

The edit form offered name, category and labels, and the address only on the way
in. The cause was not the form: the update contract never declared address, so
the validation pipe stripped it and the UPDATE had no column for it. Coordinates
were pulled through for #1435 and the address was missed.

It travels the whole chain now, contract to service to both forms. No migration,
the column has always been there.

The mobile add sheet had no address input at all, showing whatever the search
result carried as read-only, so editing would have worked while creating still
would not. It has one.

The MCP tool description had drifted further than the address, never having
mentioned the coordinates either. Both are in it now.

Closes #1870

* fix(collections): keep the place search usable after the first save

The add dialog stays open on purpose so several places can be added in a row, but
after a save it gave no way back into the search. A search with no results was
silent, with no empty state and no toast, so typing another name and pressing
enter looked like nothing happened. The reporter described both halves and it is
the silent search that matches "nothing happens" most closely.

There is an empty state now, using a key that already existed in every locale and
was unused. The search row is sticky inside the dialog body, so it stays reachable
after the save instead of sitting above the scroll position.

Also fixed while in here: refreshing the collection after each add reset the
select mode, the selection and the label filter. In the very flow this dialog is
built for, the user quietly lost all three.

Closes #1921

* fix(vacay): make the phone year grid and the dock button do what they look like

Two separate faults met on this screen.

Tapping a day in the year grid did nothing unless the edit mode was already on,
and the only way into it was a floating button that looks exactly like the one
the dock draws in the same spot. A tap now opens that month in the editor, where
the cells are big enough to hit. At 390px the grid cells are around 21px, which
is too small to be mutating data with in the first place.

The dock's plus was not wired for this route, so it fell through to creating a
trip on the dashboard. Two different actions were stacked in one place, and the
wrong one was on top whenever the screen had not painted yet, which includes the
time its chunk is still loading. The dock leaves the slot to the screen now, and
holds the geometry so the tab groups stay symmetric.

Closes #1811

* fix(budget): settle in whole cents so balances stop drifting

The report is a balance that moves on its own, with nothing added, edited or
removed, on a trip where everything is in euro. Two mechanisms were behind it and
both are real.

The display currency is a fourth value, a per-user setting, so "everything is in
euro" never covered it. Each balance was converted and rounded on its own, and
the set no longer summed to zero: at 0.855 and 0.9312 it came out one cent over,
at 0.94 it came out even. That cent appears and disappears with the six hour rate
cache alone, which is exactly the symptom. The flows were rounded separately from
the balances, so the two never had to agree.

And a receipt line nobody was ticked for counted toward the total, and therefore
toward the payer's credit, while landing in no share. That difference is
permanent, and the client sent it that way.

The settlement converts once, at the edge, and does integer arithmetic after
that. Equal splits distribute the credited cents by largest remainder rather than
the entered total, so credits and debits of one expense cancel exactly even in a
foreign currency. Display conversion goes through the same largest-remainder
allocation, so the sum survives it.

With that, the 0.01 epsilon can go. It could never create a cent, but it stranded
them: a one cent balance was filtered out of the flows while staying visible in
the list, which is the "settle up offers nothing" half of the report.

Closes #1382

* fix(journey): reach the book export and the suggestion toggle on a phone

Below 1024px the hero card is dropped, and it held the only way to either action.
The floating bar that replaces it was never given them. It has them now, and the
hero is unmounted rather than hidden, so there is no second invisible copy of the
same controls in the document. The bar's own buttons moved onto the appearance
tokens while they were being touched.

The phone screen never had either action at all and now carries both.

The book itself was hardwired to English, cover and dates included, while the
keys for it had been sitting in every locale unused. It takes the page's
translator and locale, sets the document language, and prints mood and weather,
which were on screen but never in the book.

Closes #1848

* fix(journey): offer the connected photo providers in the phone entry editor

The desktop editor grew an external photo source in #1632; the phone editor that
came out of the mobile rewrite never did, so editing an entry on a phone had no
way to Immich or Synology. It mirrors the desktop mechanics, including the part
that is easy to miss: a save that creates the entry and then fails on the photos
keeps the sheet open, and without remembering what was just created the retry
creates a second entry.

The sheet no longer kicks off its own addon load. The list is loaded once on
boot and this only reacts to it; a second load races the other consumers and
overwrites the store when it lands.

Closes #1808

* fix(mobile): let the document scroll so Safari can collapse its URL bar

iOS Safari only shrinks its address bar when the document scrolls, and TREK's
never did: the root was locked and the mobile shell put a scroll container inside
it. On the bottom tab layout that costs about a sixth of the viewport,
permanently.

Below 768px the document is the scroller again and the full-bleed screens measure
their own height instead of leaning on the shell.

That makes the body scroll locks real for the first time on a phone, and they
were not ready for it. Three of them reset the overflow unconditionally, one of
those on every run of its effect rather than on unmount, so a system notice could
hand the page back while a sheet was still open. They all go through one
reference counted lock now, which is the part that had to land first.

Worth knowing for the issue: this reaches the flow screens. The trip planner, the
journal, the atlas and the vacay screen keep their own full-height scrollers and
still will not collapse the bar.

Closes #1809

* fix(mobile): keep the screen gradient visible behind the translucent cards

The gradient layer introduced with the scroll change sat at z-index -10. A
negative layer paints above the canvas but below the backgrounds of ordinary
blocks, and body carries an opaque one, so the gradient was hidden behind it.
The mobile cards are translucent and take their depth from what is behind them,
so every surface ended up compositing against a single flat colour and the whole
phone UI read as one tone.

The layer is positioned at z-index 0 now and the content above it at 10, which
puts both over body's background. Same visual as before the scroll change, and
the shell still owns no scroll container.

* test(reservations): teach the accommodation delete stub about the id lists

The RPC walks every linked booking since the delete stopped stopping at the
first one. The stub still answered with the two singular fields, so the loop had
nothing to iterate and the cascade events never fired.

* fix(settings): move the free-form LLM endpoint out of user settings entirely

Hiding it from non-admins closed the hole, but it left the option sitting in the
admin's own personal settings, which is not what was asked for and not where it
belongs: an instance has exactly one address it calls out to, and there was a
second, invisible place to set it.

The provider list is now the two hosted ones for everybody, the endpoint field is
gone, and the resolver takes the address from the admin-controlled instance
defaults for every caller including an admin. It no longer reads the users table
at all. The write path refuses the keys for everyone, so nothing can be stored
that would never be read.

The endpoint is configured on the addon in the admin settings, which already
carries provider, model, base URL and key, plus the Ollama model list. Nothing
is lost, it just has one home now.

Behaviour change worth a release note: an admin who set a personal Ollama
endpoint has to move it to the addon config. A non-admin was already in that
position after the previous commit.

Refs #1772

* fix(journey): make the book preview usable on a phone

The preview document carried no viewport, so a phone laid it out at its default
980px while the page is A4 landscape and about 1123px wide. It spilled out of
the frame, which reads as being zoomed far in. Declaring the real width lets the
browser scale the page to fit. Printing is unaffected, it goes by @page.

The preview chrome had the same problem in miniature: a title and two labels on
one row, sized inline, which does not fit a phone and fits translated labels
even less. It moved to a stylesheet, and below 640px the card goes full-bleed,
the decorative title steps aside and the two actions share the width.

Refs #1848

* fix(mobile): stop the shell trapping the screens' own overlays

Lifting the background layer into the positioned range meant the content wrapper
had to be positioned too, and a positioned wrapper with a z-index is a stacking
context. Every fixed overlay a screen renders inside it got clamped to that
level: the vacay view/edit FAB sits at z-50 precisely so it beats the dock at
z-40, and it disappeared behind it.

The layer goes back to a negative z-index and the wrapper back to no positioning
at all. What it needed in the first place was for body to stop painting over it,
which is one line in the phone media block rather than a new stacking context.

* fix(mobile): let the phone background override actually win

A media query adds no specificity, so the themed body rule further down the file
kept winning on source order and painted over the shell's background layer. The
override is on html body now.

The gradient was back to being invisible, which is the flat single-tone phone UI
again.

* fix(vacay): draw today's ring around the day instead of replacing it

On the phone, today short-circuited the day-cell matrix and returned a ring on an
empty cell. A vacation day or a company holiday logged for today was stored and
counted in the totals, but the cell showed nothing, so it read as if the tap had
not taken.

Today is an annotation now, layered like the school band and the shared-calendar
rings, which is how the desktop month card has always treated it. The strong ink
stays only where the cell has no fill of its own, since --m-ink is light in dark
mode and would disappear on a pastel.

* fix(map): stop serving a stale GL style document from the service worker

The Workbox rule for Mapbox matched every URL under api.mapbox.com, and the
style document lives there too. Under StaleWhileRevalidate the map was built
from the previous revision on every load, with the refresh landing one load too
late, so a style republished in Studio with different label languages kept
rendering the old ones. The network tab showed a 200 throughout, because the
service worker's own answer is a real 200, which is why this looked like the app
rewriting text-field at runtime.

The style now has its own rule ahead of the tile rules, on NetworkFirst so it is
current whenever the network is, and still cached so the map opens offline. Its
own small cache too: sharing an LRU with three thousand tiles made the staleness
come and go at random. OpenFreeMap styles had the same problem and are covered
by the same rule.

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 for the details.

      timeout: 10s
      retries: 3
      start_period: 15s

Then:

docker compose up -d

HTTPS notes: FORCE_HTTPS=true is optional — it adds a 301 redirect, HSTS, CSP upgrade-insecure-requests, and forces the secure cookie flag. Only use it behind a TLS-terminating reverse proxy. TRUST_PROXY=1 tells the server how many proxies sit in front so real client IPs and X-Forwarded-Proto work.


Helm (Kubernetes)

helm repo add trek https://chart.liketrek.com
helm repo update
helm install trek trek/trek

See charts/README.md for values.

Install as App (PWA)

TREK works as a Progressive Web App — no App Store needed.

  1. Open TREK in the browser (HTTPS required)
  2. iOS: Share ▸ Add to Home Screen
  3. Android: Menu ▸ Install app (or Add to Home Screen)

TREK then launches fullscreen with its own icon, just like a native app.


Updating

Docker Compose:

docker compose pull && docker compose up -d

Docker run — reuse the original volume paths:

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.

Rotating the Encryption Key

If you need to rotate ENCRYPTION_KEY (e.g. upgrading from a version that derived encryption from JWT_SECRET):

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).

Reverse Proxy

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 for details.

Environment variables

Note

Variables are validated at startup (fail-fast). An unset or blank variable always falls back to its default, but a variable set to a malformed value (e.g. PORT=abc, SESSION_DURATION=bogus, DEMO_MODE=maybe) aborts boot with a report listing every offending variable. Boolean switches accept true/false, 1/0, on/off and yes/no (any casing).

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
TREK_WIKI_DIR Where the in-app Help pages (/help) read their content from. TREK ships its wiki and serves it from disk, so Help always matches the version you are running — you should not need to set this. Point it at your own directory to serve custom docs. If the path does not exist, Help falls back to fetching the public GitHub wiki (needs outbound network, and tracks the latest release). bundled wiki/
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
UNSPLASH_ACCESS_KEY Optional Unsplash Access Key for trip-cover and place-image search. Without one, TREK uses Unsplash's unauthenticated endpoint, which some datacenter/VPS IPs are blocked from. Get a free key at unsplash.com/developers. Overrides any per-admin key set in Admin > Settings (where it can also be configured instead). —
MCP_RATE_LIMIT Max MCP API requests per user per minute 300
MCP_MAX_SESSION_PER_USER Max concurrent MCP sessions per user. At the cap, the least-recently-active session is closed to make room 20
