The page reads one window anchored on today, ninety days back and half a
year forward, and the month grid navigates freely past it. A month
outside the window came back with no days: the cells still rendered
(they come from the month, not the read) and still opened the log sheet,
and the write behind it still landed, because the period route is built
for back-dating and re-anchors the neighbouring cycles for it. What did
not happen is anything visible. Saving an April flow in August closed
the sheet onto a month the read never carried, so the entry looked like
it had not been made, and entering it again did not help.
The grid now reports the month it moved to and gets its own bounded read
for it. The anchored window is untouched, because every other surface on
the page means today and the route caps a span at 400 days, so a union
with a month two years back would simply be refused.
A write also says so now. Saving, deleting and both period boundaries
raise a confirmation; the sheet's inline strip already named a failure.
Between the invisible month and the silent success there was no way to
tell a save that worked from one that never happened.
The sheet header carries the date it is writing to, and the one-tap
boundaries drop the word today when the day is not today. It always
wrote to the selected date; saying otherwise made a correction read as a
mistake.
The gear beside the log button is gone. It was a second door to the tab
directly below it and no other page carries one in that corner.
- calendar days carry isCycleStart, so the delete dialog can say that
removing this day removes the period start with it
- window arithmetic is a pure module with its own tests, including the
400-day span the anchor cannot be widened past
- integration: a day 111 back is written, is absent from the anchored
read, and comes back complete on a window over its month
- new strings in all six languages
Every route that resolves a record through the sharing fence can answer 403
`sharing.access.denied`, and until now that fact was published on the selector
header and on none of the 120 operations that produce it. All 120 carry it now,
byte for byte, from one constant: the refusal is deliberately indistinguishable
across a missing account, a missing grant, a scope that does not reach the
surface and a read grant on a write, so 120 paraphrases would invite a client to
tell apart what the server refuses to.
Where a delegable route already answered 403 for its own reason — a module
gate, the cycle gate, AI consent — the two share one description rather than one
of them going unpublished, since OpenAPI allows a single response per status.
The guard recomputes the delegable set from the route sources on every run and
classifies per verb, which matters: seventeen modules have a delegable read
beside a write that refuses a switch outright.
The cycle ring's day count, its phase arcs, and the judgement that a period
is late all used to be worked out in web client code, including the
fourteen-day grace window that decides when the count stops being an
observed fact. Anything else that wanted the same answer had to reproduce
that rule, and a second copy of it is how a ring ends up showing someone a
cycle day their record does not hold.
GET /api/cycle/calendar now carries a verdict: the state, the cycle day,
the ring's arcs, the cycle start, how many days until the next period, and
when the period is late, how late. It is resolved against the user's own
timezone day, which a browser in another zone cannot do. The web wheel,
the wellness-strip tile, the insights teaser and the temperature chart all
render it, the grace constant is gone from the components directory, and
the spec says the field is required.
The overdue caption now names the number of days instead of only saying
later than usual.
Let a user pick the Sensiplan double-check's second indicator — cervical
mucus (default) or cervix observation — mirroring the published NFP
standard where the temperature primary sign pairs with one chosen
secondary sign.
- `CycleProfile.secondarySymptom` (MUCUS default | CERVIX) drives which
second sign the engine confirms against. Casual users keep temperature
+ mucus untouched; the choice lives behind the advanced cycle settings.
- `CycleDayLog` gains the three standard cervix signs — position
(LOW/HIGH), firmness (FIRM/SOFT), opening/os (CLOSED/OPEN) — as nullable
columns (migration 0157), wired through Zod, the day-log upsert, the
DTO, the sync feed, backup/restore and OpenAPI. Additive and
back-compatible: existing profiles backfill MUCUS, existing day-logs
keep NULL cervix signs, iOS inherits the fields.
- The engine's `confirmSymptothermal` takes the secondary-symptom choice;
on CERVIX it confirms against `detectCervixPeak` (last fertile-cervix
day followed by three closed days — the cervix-closure rule) instead of
the mucus peak. The double-check still requires BOTH the temperature
shift AND the secondary peak: a single cervix sign never confirms, and
the still-learning gate and conservative posture are unchanged.
Engine derived clean-room from the Arbeitsgruppe-NFP / Raith-Paula &
Frank-Herrmann standard.
A fever, illness, alcohol or a late/short-sleep reading can fake or mask
a temperature rise. Add a per-day `temperatureExcluded` flag on
CycleDayLog (migration 0156): when set, the engine drops the reading from
the cover-line baseline AND the shift evaluation, so a spike neither
fabricates nor masks a rise (Sensiplan: the cover line is drawn over the
last six unbracketed values).
Wired end to end — schema + Prisma, the engine's `detectTempShift`
filter, the Zod input/patch schemas, the day-log upsert (partial merge +
change detection), the read DTO, the calendar/insights/coach selects, the
backup round-trip, and the OpenAPI contract (a new boolean on the day-log
and calendar-day DTOs for the iOS client). The log-day sheet gains a
"mark reading as disturbed" toggle that appears once a temperature is
entered, translated across all six locales.

The predictions panel suppressed its fertile-window and ovulation rows while
fewer than three cycles were observed, but the month calendar did not — so a
brand-new user who logged a single period saw the grid paint a confident
fertile-window shading, a predicted-ovulation dot, and full phase bands off a
population 28/14 prior at ~0.20 confidence. Calendar-based fertility estimation
is unreliable below several recorded cycles, so the grid was asserting days it
could not know.
Thread the same still-learning gate into the calendar build: while fewer than
three cycles are observed, suppress the fertile window, the ovulation dot, and
the phase band (the predicted-period bar stays, mirroring the panel). Surface a
top-level stillLearning flag on the calendar response so the client renders a
calm "learning your cycle" banner over the grid instead of a bare, falsely
confident calendar. The flag is additive and back-compatible; older clients
ignore it and degrade to the previous render.
Also pin the observed-cycle count to a single source — the engine's
post-exclusion value — so the response never carries two divergent counts.
The five-thousand-line route registry splits into thirteen domain
modules and the query-key factory into twelve feature files — each
behind an index that preserves exact registration order, proven by a
byte-identical generated contract. The factory lint rule learns the new
home directory.
