The per-account preview switch was kept for the topic overview pages,
which were dropped before they shipped. Its one flag was stored, served
and backed up, and read by nothing; the column-reader audit listed it as
a pending consumer that will not come.
Removed completely:
- `/api/settings/preview-features` (GET, PATCH) is retired: it answers
410 Gone with `meta.errorCode: route.retired` and `removedIn: 1.46.0`,
and the contract publishes it under Retired. The route, its validation
schema, the `PreviewFeatures` OpenAPI schemas and the settings module
are deleted.
- Migration 0485 drops `users.preview_features_json` under a bounded lock
wait, with the retry marker.
- The backup no longer writes the field. A file from v1.44 or v1.45 that
carries it still restores: the schema accepts it and no codec reads it,
so nothing is refused or written for it. The backup-parity goldens
lose the field and apply one setting fewer.
- The data-wipe plan entry and the sharing-surface actor entry go with
the route (frozen count 273 -> 272).
No client build reads the route: neither iOS repository nor any local
checkout references it.
/topics shows a tile per topic the record holds data for, and names the
empty topics and the module-hidden ones once each. /topics/<topic>
shows the topic today, its signals side by side over 7, 30, 90 days or
a year against their usual range, how they move together, their trends,
its blocks, the single-metric pages behind it and what it is missing.
Every topic links into the metric pages, which stay as they are, and
each page ends on a neutral note that this is a preview.
Settings > System > Preview features is listed again and switches the
area on for the person reading. While it is on, the sidebar carries a
Topics entry with a Beta badge directly below Insights and the phone's
More sheet leads with a Topics tile; the bottom bar does not change.
The pages leave for Insights when the switch is off.
The charts load through the shared chart runtime. The sidebar rows move
into their own module and the More sheet tile into its own component,
so neither shell file grows; the lab trend wording is shared between the
marker page and the metabolism topic. Copy in all nine locales.
GET /api/topics answers one entry per topic the record holds data for:
a headline value, a rule-based sentence and a 30-day sparkline.
GET /api/topics/{topic} answers a topic's signals with their usual
ranges, side-by-side series for a chosen window, the relationships
between its signals, 90-day trends, what it holds nothing for yet, and
its blocks (training load, lab markers with their trend, screener
trends, the cycle day).
Every figure comes from reads the metric pages already make: the local
daily values, the reconstructed nights, the mood score, computeLabTrend,
the training load and the screener trends. No model is involved. A
relationship says nothing below 14 paired days and is only called a
pattern at p < 0.05; a lab trend needs three readings spanning a year.
The preview is the viewer's own opt-in: with it off both routes answer
404 topics.preview_off. Topics, signals and blocks follow the record's
module switches and the sections the viewer's grant opens; the routes
read across sections, so a scoped grant is refused like the timeline.
/api/auth/me publishes the caller's opt-ins as previewFeatures.
An app boot's /api/auth/me read the AppSettings singleton six times, each
reader with its own few columns: the MFA policy, the Assistant switches,
the module availability, the provider presence, the AI usage bounds and
the reasoning controls. They now take their columns from one read,
memoised for the request and read afresh inside a background job like the
readers themselves. No answer changes.
Add the in-repo rule `healthlog/import-boundaries`:
- a file under src/lib may not import src/components or src/app (alias,
relative, re-export and dynamic forms, type-only included);
- a "use client" file may not make a value import of the database client,
the crypto module, the Prisma client entry, the job queue, pg, pg-boss or
next/headers. Type-only imports and the Prisma enums entry stay legal.
The four lib files that still import upward are listed in the rule's allow
map with a reason each; a listed file that stops importing upward is
reported, so the map can only shrink.
Five of the nine upward imports are gone by moving pure modules to their
layer, without behaviour change:
- supply-runway estimate → src/lib/medications/supply-runway.ts
(read by the low-stock job and the medication list read);
- weekday BYDAY tokens → src/lib/medications/scheduling/weekday-tokens.ts
(read by the medication extraction prompt);
- settings section slugs → src/lib/settings/section-slugs.ts
(read by the record-settings classification);
- the command palette index → src/components/command-palette/ (it is a
client index built from component registries).
Proof the rule can fail: an import of @/components/ui/card appended to
src/lib/medications/supply-runway.ts reported libUpward, and a planted
"use client" file importing @/lib/db reported clientServerOnly; both were
removed again.
The switch was stored and shown, but nothing reads the topics flag
yet, so the page promised a change it could not make. The section,
its nav entry, its loader and its copy are gone, so its palette
entry goes with them; /settings/preview is no longer a route. The
stored flag, /api/settings/preview-features and its backup round-trip
stay, and the column's pending-consumer note says why.
Settings now reads as nine groups: Account, Tracking, Arrangement,
Notifications, Health profile, AI, Connections, Data and System. On a
phone one button names the current section and opens the grouped list,
replacing the strip of every section.
What moved, every old address still working:
- Sessions, trusted devices and security activity sit under Security;
the privacy page anchors forward there.
- Notifications holds every reminder kind: the Coach nudges and the
checkup reminder switches joined, and a card names the reminders set
where their subject lives (dose times, cycle reminders).
- Arrangement holds order and view only. Mood tags, the labs biomarker
catalog and on-device text recognition, and the injection sites live on
module pages under /settings/modules/<id>, linked from each Modules row
and from the module's own wrench. /settings/layout/mood redirects.
- The timezone saves on change in the Display card, with a one-tap offer
of the device zone.
- Screening hints sit beside the life circumstances they come from.
- System gains Preview features with the Topics switch.
Duplicates: the Coach and MCP pages show their state and link to the one
switch in Modules (turning MCP off keeps tokens), the Coach overlay shows
the provider and model with a link to Settings > AI instead of a second
set of selects, and the privacy page drops its copy of the export links.
A guard walks every historical /settings address through the redirects
and every forwarded anchor to a page that renders.
Add per-user columns for the labs, illness and checkups list presentation
and for preview-feature opt-ins, each with a GET plus a preserve-when-absent
write under /api/settings. The list hook now reads and writes the server
value and carries a browser-stored order up once when the server holds
none, so an existing arrangement follows the person to every device instead
of resetting.
