Adds a tide dashboard widget showing the tides of a house by the sea: a harbour tide clock, the next high and low water, the water level right now, and the curve of the day annotated with each tide. A row of tabs steps through the week ahead, one day at a time. On the French coast it also shows the tide coefficient.
How tides are computed
Tides are predicted locally. The harmonic constituents of the tide station closest to the house are downloaded once from the Open Waters tide database (MIT code, CC-BY-4.0 data, built from the NOAA and TICON-4 datasets) and stored in a per-house variable. Every prediction afterwards is computed offline: the widget keeps working with no network access, and a station that can no longer be downloaded is kept rather than dropped.
Predictions were checked against the tide tables published by the SHOM for Concarneau: times land within 1 to 4 minutes, heights within about 20 cm.
Places with no tide to show
A house inland matches a harbour hundreds of kilometres away, and the Mediterranean or the Baltic move by a few centimetres. Rather than drawing a flat curve, the widget says which of the two it is — the cases are told apart by the distance to the station and by the spring range, and worded differently.
A third case says the tide could not be retrieved at all: failing to reach the station database says nothing about where the house is, so a seaside house is never told it is inland because the network was down.
The tide coefficient
On the French coast the widget shows the tide coefficient, computed on the semi-diurnal constituents alone, the way the SHOM publishes it. Keeping the diurnal ones makes the morning and the evening tide of a same day differ by ten points, which published coefficients never do. Brest harmonics are embedded, so the coefficient needs no second download.
New dependency
@neaps/tide-predictor (MIT, ~217 KB unpacked, no transitive dependencies).
It is an ES module while the server is CommonJS, so it is loaded through a memoized dynamic import() in server/lib/house/house.getTideState.js — the only dynamic import() in the server, which is why docs/specs/tide-widget.md explains it.
Reimplementing it would be wrong rather than merely tedious: harmonic prediction needs the astronomical equilibrium arguments and the nodal corrections following the 18.6-year lunar cycle. A naive sum of cosines written with the real Saint-Malo constituents lands 2.4 to 6.2 m off across four dates spread over a year (table in the spec). There is no CommonJS equivalent on npm.
The dynamic import() is safe here: production installs run npm ci --production with no bundler, Node 24 supports it natively, and tests cover it including the offline path.
API
One new route:
GET /api/v1/house/:house_selector/tide
Returns the tide state of the house: the tides framing the current moment, the water level, the curve of the day, and the coefficient where it applies. ?day_offset= selects a day within the week ahead. Returns 400 when the house has no coordinates.
Adds tide prediction with cached stations, an authenticated API endpoint, demo data, and a configurable dashboard widget. The widget displays forecasts, curves, coefficients, current levels, availability states, responsive styling, and localized text.

Tide prediction and state computation server/lib/house/house.getTideState.js, server/test/lib/house/house.getTideState.test.js
Computes harmonic predictions, local-day curves, coefficients, tide ranges, station states, and unavailable-state reasons. Tests cover prediction, caching, retries, daylight-saving transitions, and edge cases.
Authenticated tide API server/api/controllers/house.controller.js, server/api/routes.js, server/test/controllers/house/house.test.js
Adds the authenticated tide endpoint with coordinate validation and day_offset handling.
The tide widget can currently consume attacker-controlled or malformed shared cache records, causing incorrect or unavailable tide data for houses, while several UI and date/time edge cases remain unresolved. These bounded correctness and availability risks should be fixed or explicitly accepted before merging.

Stale comment
Thanks for this — the local-harmonics approach (download once, predict offline), the three unavailable reasons, and the SHOM coefficient checks are a solid design, and the spec does a good job explaining why @neaps/tide-predictor is loaded with a dynamic import().
I am requesting changes before merge. Nothing here is brand-tied device taxonomy (DASHBOARD_BOX_TYPE.TIDE only), and this is not risk:high (additive widget + authenticated GET, no actuation). It does need another pass on DST, station-refresh backoff, the house-switch race, and patch tests — Codecov will fail 100% patch coverage on several untested getTideStation / helper branches.
Blocking
DST end of day — endOfDay = startOfDay.add(1, 'day') is the pattern the sun widget already rejected. On a Paris spring-forward day that lands one hour into the next calendar day, not on local midnight. The comment on that line is therefore wrong, and curve.length === 145 only holds on 24-hour days. Mirror house.getSunState.js (re-parse both midnights from YYYY-MM-DD) and add the 29 Mar / 25 Oct 2026 tests.
Stale-station retry storm — after 30 days, a failed refresh leaves downloaded_at untouched, so every 60s widget poll hits Open Waters again and can block for the 10s axios timeout. Record a backoff (or bump downloaded_at on failure) so a down database does not hang the dashboard once a month.
In-flight request vs empty house — refreshData returns before incrementing requestId when box.house is missing, and does not clear tideState. The sun widget already fixes this. A late response from the previous house will overwrite the empty state.
Patch tests — moved house, corrupt JSON, outdated refresh success/failure, download-empty-with-stored, empty harmonics, and getSpringTideRange without MHWS/MLWS are not executed. CI requires 100% patch coverage on server lines.
Also fix
Spec “Places with no tide” still lists only two reasons; station_unavailable is in the code and the PR body.
Day tabs / times are hardcoded DD/MM and HH[h]mm on a worldwide widget; current_height under the curve is always now, including when a future day is selected.
Rising/falling tooltip is English-only (title={rising ? 'rising' : 'falling'}).
Non-blocking / for Pierre
I am adding needs:human-review and requesting Pierre-Gilles: new wall-panel widget (clock + curve + French coefficient), auto-pick of the nearest station with no override, and a new outbound call that sends the house coordinates to api.openwaters.io on first load. Soft residuals: no demo GET .../tide fixture (adding the widget on demo.gladysassistant.com would 404), skeleton height falls through to 140px, MAX_COEFFICIENT_DISTANCE_KM = 1200 will print a Brest/SHOM coefficient in the UK/Ireland.
Not risk:high. No DEVICE_FEATURE_CATEGORIES / TYPES changes.

Render the house-loading state.
getHouses sets pending and error, but render only reads houses and does not pass either state to EditTideBox. When /api/v1/house fails, the editor shows the same empty selector as a successful empty response and gives no failure or retry feedback. Pass these states to the editor and render localized loading and error messages.

Thanks for the follow-up — DST midnight re-parse (with the 29 Mar / 25 Oct 2026 tests), the 6-hour refresh backoff on thrown errors, requestId vs empty house, locale times, hiding current_height on future days, station_unavailable in the spec, the demo fixture, and the skeleton height all look right. Nothing here is brand-tied device taxonomy (DASHBOARD_BOX_TYPE.TIDE only), and this is still not risk:high (additive widget + authenticated GET, no actuation).
I am requesting changes once more because codecov/patch is already red on this head (99.39%, 4 missed lines). CI requires 100% patch coverage on server lines.
Blocking
Four untested returns in house.getTideState.js — Codecov reports lines 143–144 and 214–215 never execute:
computeTideCoefficient when there is no high-then-low pair (return null)
getSpringTideRange when the fortnight of extremes is empty (return 0)
Both were called out last round; the MHWS/MLWS fallback is now covered, these two bodies are not.
Empty refresh still retries every poll — last_failure_at is only written in the catch. If the database answers [] (or a station with no harmonics) after STATION_MAX_AGE_DAYS, the stored station is returned without recording the attempt, so the widget’s 60s poll hits Open Waters again. The new “keep the stored station when the database returns none” test only calls once, so it does not catch this. Please persist last_failure_at on that path too. Same file: failedRecently is ignored when movedAway is true, so a house that just changed coordinates retries every minute while the database is down.
Residual / for Pierre
Keeping needs:human-review and the request on Pierre-Gilles: new wall-panel widget (clock + curve + French coefficient), auto-pick of the nearest station with no override, and a new outbound call that sends the house coordinates to api.openwaters.io on first load. The 700 km coefficient radius (UK/Ireland inside, Lisbon/Hamburg/Marseille out) is now documented; worth a maintainer look, not a code-review block.
Non-blocking: Number.parseInt of a garbage day_offset is NaN, and options.dayOffset || 0 does not clamp it (NaN is truthy). The widget only sends 0–6.
Not risk:high. No DEVICE_FEATURE_CATEGORIES / TYPES changes.
Do not make tide availability depend on cache writes.
At Line 69, a this.variable.setValue failure enters the outer catch. A successfully downloaded station is then discarded and the widget reports station_unavailable. At Line 86, failure to store last_failure_at also discards an already usable cached station.
Handle cache-write failures separately. Return the downloaded or cached station after logging the persistence failure. Add tests for both setValue rejection paths.
As per coding guidelines, “If you add a branch, error path, or helper, write a test that hits it.”

Day.js 1.10.6 timezone plugin add day DST retained offset toDate format issue
💡 Result:
The issues you are encountering with the Day.js timezone plugin—specifically regarding Daylight Saving Time (DST) offsets and inconsistent toDate() or format() results after arithmetic—are well-documented, long-standing behaviors in the library [1][2][3]. These problems primarily stem from how Day.js handles timezone offsets, often relying on the host environment's system timezone or incorrectly recalculating offsets during calendar arithmetic (like add or startOf) [2][3][4]. Common issues and findings include: - Inconsistent arithmetic: Methods like add(1, 'day') may not correctly account for DST shifts, leading to results that are off by one hour because the offset is not recomputed properly after the change [2][5]. - Host dependency: Certain operations have historically leaked the host machine's timezone settings into calculations, causing discrepancies when the host and the target timezone are in different DST states [3]. - toDate() and format() behavior: When converting to a native Date object or formatting, the underlying UTC value may be reinterpreted based on the current context, especially if the tz() call is chained incorrectly [2][6][7]. Workarounds and Best Practices: - Change the order of operations: If you are experiencing issues with arithmetic, try performing the calculation before applying the timezone, or re-applying .tz() after the operation [2][4]. Example: Instead of dayjs.tz(time, tz).add(1, 'day'), try dayjs.tz(time, tz).add(1, 'day').tz(tz) or dayjs.tz(dayjs.tz(time, tz).add(1, 'day').valueOf(), tz) to force an offset recalculation [2][8][5]. - Use explicit timestamp construction: Where possible, use .valueOf() to obtain the raw Unix timestamp and re-wrap it in dayjs.tz() to ensure the correct offset is applied for that specific instant [9][8][5]. - Monitor for updates: The library has received several fixes targeting these behaviors, including PRs aimed at preserving timezone context and improving offset calculation [8][5][3]. Ensure you are using the latest version of Day.js, as behaviors have evolved significantly since 1.10.6 [10][5]. If your application relies heavily on complex timezone arithmetic, these structural limitations are significant, and developers often find that performing time-zone-aware calculations requires careful management of the order of chained methods to ensure the internal offset remains synchronized [2][8].

To use timezone functionality in Day.js (including v1.10.6), you must extend the library with both the UTC plugin and the Timezone plugin [1][2]. The Timezone plugin is dependent on the UTC plugin, and failing to load both will result in errors [1][2]. To add or change a timezone and update the offset, you use the.tz method provided by the Timezone plugin [1][3]. Implementation Example: javascript import dayjs from 'dayjs'; import utc from 'dayjs/plugin/utc'; import timezone from 'dayjs/plugin/timezone'; // Extend dayjs with the required plugins dayjs.extend(utc); dayjs.extend(timezone); // Converting to a specific timezone: // This updates the offset and the time to match the new zone const dateInNewYork = dayjs('2013-11-18T11:55:20').tz('America/Toronto'); // Result: '2013-11-18T05:55:20-05:00' // Keeping local time when changing timezone: // Pass 'true' as the second parameter to keep the local time while changing the offset const dateKeptTime = dayjs('2013-11-18T11:55:20').tz('America/Toronto', true); // Result: '2013-11-18T11:55:20-05:00' If you need to manually set a specific UTC offset (without using IANA timezone names or DST rules), you should use the.utcOffset method from the UTC plugin rather than the Timezone plugin [4]. javascript // Set UTC offset to +8 hours dayjs.utcOffset(8); // Set UTC offset to +8 hours, keeping the same local time dayjs.utcOffset(8, true);
Keep each tab label on one house-local calendar day.
When day crosses a DST transition, .add(offset, 'day') can retain the previous offset. day.format('ddd') reads the calendar fields, while day.toDate().toLocaleDateString() formats the shifted instant. A tab can show a mismatched weekday and date.
Derive a YYYY-MM-DD calendar key first. Recreate that date in timezone, then format both weekday and date from that value.

Build demo forecast days in Europe/Paris.
When the browser timezone differs from Europe/Paris, dayjs() creates day, endOfDay, and curve boundaries in the browser timezone. TideCurve positions hour marks using the returned station timezone, so the curve and displayed day boundaries can be shifted relative to each other. Reparse both boundaries in Europe/Paris so DST days use the correct local midnight.

Predicts tides from the harmonic constituents of the tide station closest
to the house, downloaded once from the Open Waters database and then kept
locally: predictions are computed offline and keep working with no network
access. Checked against the SHOM tables in Concarneau, times land within a
few minutes and heights within 20cm.
Places with no tide to show say so instead of drawing a flat curve: a house
inland matches a harbour hundreds of kilometers away, and the Mediterranean
or the Baltic move by a few centimeters. The two cases are told apart by the
distance to the station and by the spring range, and worded differently.
On the French coast the widget also shows the tide coefficient. It is
computed on the semi-diurnal constituents alone, the way the SHOM publishes
it: keeping the diurnal ones makes the morning and the evening tide of a
same day differ by ten points, which published coefficients never do. Brest
harmonics are embedded, so the coefficient needs no second download.
The widget shows a harbour tide clock, the next high and low water, and the
curve of the day annotated with each tide and its coefficient. A row of tabs
steps through the week ahead, one day at a time.
The dynamic import() of @neaps/tide-predictor is the only one in the
server, which makes it look accidental. Records that it is deliberate,
and what would justify revisiting it.
Reimplementing the prediction was measured, not assumed: a naive sum of
cosines over the real Saint-Malo constituents drifts by up to 6.20m
against the library, because harmonic prediction needs the astronomical
equilibrium arguments and the nodal corrections of the 18.6-year lunar
cycle. No CommonJS equivalent exists on npm — the one package named
"harmonics" is an unrelated music library.
The import is safe here: no bundler runs on the server, and production
is Node 24.
The hand was placed from the share of the half-cycle already elapsed, while
the hour numbers are laid out six hours per half turn. A half-cycle really
lasts 6h12 on average and swings between 5h30 and 6h50, so the two scales
never coincided: the hand pointed at 4 while the widget announced 5h22 before
the next tide.
It now derives its angle from the hours left, the same value spelled out
under the hub. For one to five hours left, rising or falling, the hand lands
on its matching graduation; with no time left it points at high water at the
top or low water at the bottom.

Being unable to reach the station database said nothing about where the house
is, yet the widget answered "this house is not by the sea": getTideStation
returned null both when the database had no station to give and when the
download failed, and the front fell back on the inland wording for anything
that was not a negligible tide. A house on the coast was told it was inland
whenever the network was down on the very first load.
A failed download with no station stored yet now raises rather than returning
null, and the widget has its own reason for it, worded as a failure and shown
as an error rather than as one of the two geographical explanations. A station
downloaded earlier is still used as before, so a known harbour keeps
predicting tides offline.

The shared sinon singleton accumulates every fake of the whole suite, which
the project forbids in test files. It was the only lint error on the branch.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The window was closed with add(1, 'day') on a dayjs.tz object, which keeps the
original UTC offset and so adds a fixed 24 hours. On the day the clocks go
forward in Paris the curve ended at 01:00 the next morning, and on the day they
go back it stopped an hour short of midnight -- the opposite of what the comment
on that line claimed.
Both midnights are now re-parsed from their local date as wall clock times, the
way house.getSunState.js already does it, and the loop closes on the next local
midnight whatever the last step landed on: a 23-hour day does not end on a round
number of steps.

Once the stored station passed its month, a failed refresh left downloaded_at
untouched, so it stayed outdated and every widget poll called the database
again -- one call a minute, each holding the dashboard for the request timeout
when the database is down.
The failure is now recorded next to the station and the refresh waits six hours
before trying again. The stored harmonics keep predicting the tide meanwhile,
so waiting costs nothing, and the very first download is untouched: only the
refresh of an already known station backs off.

The comment said past this distance from Brest "the local regime is another one
(the Mediterranean, the North Sea)", but 1200 km excluded neither: Marseille is
949 km away, Hamburg 1163 km and Lisbon 1137 km, all inside the radius. Only the
negligible-range check kept the coefficient off the Mediterranean, and nothing
kept it off the German Bight or the Portuguese coast, which have a real range.
700 km covers the whole French coast where the coefficient is published (Dunkirk
575 km, Hendaye 597 km) and stops short of those three. Britain and Ireland stay
inside it: they are closer to Brest than the Basque coast is, and share the
Channel and Atlantic regime, even though their own services do not publish the
coefficient.
The spec records the reasons, and the station_unavailable case added earlier is
documented there too.

Adds the cases the branch changed or left untested: both daylight saving days
(23 and 25 hours, curve starting and ending on a local midnight), a house that
moved, a stored value that cannot be parsed, a station past its month, a failed
refresh not retried on the next poll and retried once the backoff has passed, a
database answering with no station, a station published without harmonics, a
coast with another tidal regime, and getSpringTideRange with and without the
spring datums NOAA stations do not publish.
The variable store is handed back by the test helper so a test can date what was
stored and read what the house wrote to it.

The widget covers harbours worldwide but printed French conventions everywhere:
"08h22" and a "DD/MM" date read as foreign to half of them, and the hour axis of
the curve was labelled by counting six hours from midnight, which drifts by an
hour when the clocks change -- the mark written "06h" fell at 05:00. Times, tab
dates and axis labels now go through toLocaleTimeString / toLocaleDateString in
the house timezone, and the axis marks are re-parsed on the local clock so they
stay on round hours. The tide clock countdown keeps its "5h22" form: it is a
duration, and reads the same everywhere.
Two more fixes in the same pass:
- refreshData returned before invalidating the request id when the box had no
house, and left the previous tide in the state, so a late response of the
house selected before could overwrite the empty widget. It now invalidates
first and clears the state, like the sun widget.
- the water level is the one right now, so it is no longer printed under the
curve of a future day, where it read as that day's level.
- the rising/falling arrow tooltip was hardcoded English; it goes through the
translations now.

The demo had no route for the tide, so adding the widget on the public demo
answered 404 and showed an error. The fixture computes the tide from the current
date rather than freezing it, like the weather and the sun already do: a tide
table from a past year looks broken on a showcase. It gives four tides a day
drifting by the usual fifty minutes, a range between 1.7 m and 11.9 m, and a
coefficient following the moon from 45 at neap to 115 at spring.
It shows Saint-Malo rather than the demo house itself, which sits in Paris: a
real request there answers that the house is not by the sea, which would show
the widget explaining it has nothing to draw.
The dashboard skeleton had no height for the tide box either and fell back on
the default 140px, which is shorter than the widget: it now stands at the height
of the dial and the tide lines, or of the curve and its day tabs when the curve
is displayed.

A station stored before the house moved describes another shoreline. It was
still used as a fallback when the database answered with no station, and again
when the download failed, so a house moved from Nice to Saint Malo could be
shown the Mediterranean tide under a Channel harbour's name.
The stored station is now a fallback only while the house has not moved. After
a move, no station reads as "away from the sea" and a failed download reads as
"database unreachable", which is what each case actually is.

COEFFICIENT_CONSTITUENTS listed the semi-diurnal constituents the coefficient is
defined on, but nothing filtered anything with it: Brest's embedded harmonics
already hold no diurnal term, so the set was exported and never read. The spec
pointed at it as if it were the mechanism.
Both now say the same thing: the filtering lives in the embedded harmonics.
Also covers the day_offset branch of the tide endpoint, which no request hit.

The editor already tracked pending and error while fetching the houses, but the
render read neither: a failed GET /api/v1/house showed the very same empty
selector as an account with no house, leaving the user to wonder which it was.
The failure is now stated, and the selector is held disabled while the list is
still on its way.

Reset the boundary when the widget configuration changes.
After a render exception, Line 86 uses only props.box.type as resetKey. Updating the house or another configuration value keeps that key unchanged, so ErrorBoundary retains its error and does not render the corrected widget. Include a stable configuration revision or value in the reset key.

The `tide` dashboard widget shows the tides of a house by the sea: the tides framing the current moment, the water level right now, the curve of the day, and — on the French coast — the tide coefficient. A row of tabs steps through the week ahead, one day at a time.
Tides are **computed locally**. The harmonic constituents of the tide station closest to the house are downloaded once from the [Open Waters tide database](https://openwaters.io/tides/database) (MIT code, CC-BY-4.0 data, built from the NOAA and TICON-4 datasets) and stored in a per-house variable. Every prediction afterwards is computed offline: the widget keeps working with no network access, and a station that can no longer be downloaded is kept rather than dropped.

Thanks for the follow-up — the previous blockers are addressed on this head, and CI is green including codecov/patch (100%) and Cypress.
Nothing here is brand-tied device taxonomy (DASHBOARD_BOX_TYPE.TIDE only). This is still not risk:high: additive dashboard box + authenticated GET, local prediction after one download, no actuation. Same class as the sun / moon widgets.
What landed since last review
Patch coverage — computeTideCoefficient with no high-then-low pair, and getSpringTideRange with an empty fortnight, now have helper tests. Codecov reports every changed server line executed.
Moved house — a stored station is a fallback only while the house has not moved. Empty lookup after a move is no_station_nearby; a failed download after a move is station_unavailable. No more Mediterranean curve under a Channel harbour name.
EditTide now shows a warning when GET /house fails and disables the selector while the list is loading.
Unused COEFFICIENT_CONSTITUENTS is gone; the spec matches the embedded Brest series. Controller test covers ?day_offset=.
Earlier fixes (DST midnight re-parse, thrown-error 6h backoff, requestId vs empty house, locale times, hiding current_height on future days, demo fixture, skeleton height, 700 km coefficient radius) still look right.
Residual (not blocking)
An empty refresh ([] / no harmonics) after STATION_MAX_AGE_DAYS still returns the stored station without writing last_failure_at, so that path can hit Open Waters on every 60s poll. Thrown errors (the 10s hang) are backed off. An empty 200 for a known coastal station is unlikely if the database is up; a small follow-up could persist last_failure_at on that branch too.
After a move, backoff is skipped on purpose so the old shoreline is never shown. That treats the new coordinates like a first download.
Day-tab weekday vs toLocaleDateString can disagree for about an hour before a DST spring-forward (add(offset, 'day') keeping the old offset). The curve itself is already re-parsed from YYYY-MM-DD.
The demo fixture builds the curve in the browser timezone while advertising Europe/Paris; visitors outside Paris can see shifted hour marks. Showcase-only.
For Pierre
Keeping needs:human-review and the request on Pierre-Gilles: new wall-panel widget (harbour clock + curve + day tabs + French coefficient), auto-pick of the nearest station with no override, and a new outbound call that sends the house coordinates to api.openwaters.io on first load / 30-day refresh. The 700 km coefficient radius (UK/Ireland inside, Lisbon/Hamburg/Marseille out) is documented; worth a maintainer look, not a code-review block.
Not risk:high. No DEVICE_FEATURE_CATEGORIES / TYPES changes.

What this does
Adds a tide dashboard widget showing the tides of a house by the sea: a harbour tide clock, the next high and low water, the water level right now, and the curve of the day annotated with each tide. A row of tabs steps through the week ahead, one day at a time. On the French coast it also shows the tide coefficient.
How tides are computed
Tides are predicted locally. The harmonic constituents of the tide station closest to the house are downloaded once from the Open Waters tide database (MIT code, CC-BY-4.0 data, built from the NOAA and TICON-4 datasets) and stored in a per-house variable. Every prediction afterwards is computed offline: the widget keeps working with no network access, and a station that can no longer be downloaded is kept rather than dropped.
Predictions were checked against the tide tables published by the SHOM for Concarneau: times land within 1 to 4 minutes, heights within about 20 cm.
Places with no tide to show
A house inland matches a harbour hundreds of kilometres away, and the Mediterranean or the Baltic move by a few centimetres. Rather than drawing a flat curve, the widget says which of the two it is — the cases are told apart by the distance to the station and by the spring range, and worded differently.
A third case says the tide could not be retrieved at all: failing to reach the station database says nothing about where the house is, so a seaside house is never told it is inland because the network was down.
The tide coefficient
On the French coast the widget shows the tide coefficient, computed on the semi-diurnal constituents alone, the way the SHOM publishes it. Keeping the diurnal ones makes the morning and the evening tide of a same day differ by ten points, which published coefficients never do. Brest harmonics are embedded, so the coefficient needs no second download.
New dependency
@neaps/tide-predictor (MIT, ~217 KB unpacked, no transitive dependencies).
It is an ES module while the server is CommonJS, so it is loaded through a memoized dynamic import() in server/lib/house/house.getTideState.js — the only dynamic import() in the server, which is why docs/specs/tide-widget.md explains it.
Reimplementing it would be wrong rather than merely tedious: harmonic prediction needs the astronomical equilibrium arguments and the nodal corrections following the 18.6-year lunar cycle. A naive sum of cosines written with the real Saint-Malo constituents lands 2.4 to 6.2 m off across four dates spread over a year (table in the spec). There is no CommonJS equivalent on npm.
The dynamic import() is safe here: production installs run npm ci --production with no bundler, Node 24 supports it natively, and tests cover it including the offline path.
API
One new route:
GET /api/v1/house/:house_selector/tide
Returns the tide state of the house: the tides framing the current moment, the water level, the curve of the day, and the coefficient where it applies. ?day_offset= selects a day within the week ahead. Returns 400 when the house has no coordinates.
