Every payload a client renders a capture time from now carries `wall_clock`, a naive ISO-8601 string computed by the existing `date_view::row_display_wall`: the camera's wall clock (true instant + camera offset; the owner's display zone without an offset), with the per-source fallback for unconverted rows. Clients render it verbatim and do no zone math, which is the FileViewer-React #33 / Apollo #37 flip with the rule kept server-side: the drain's permanent `date_utc IS NULL` floor (#120: edited/exported files) would otherwise force every client to carry the per-source legacy conventions forever, and insight prompts already use the same function, so prompt and UI agree by construction. - `/image/metadata` (+ the GPS / date / date-clear mutation responses): `file_wall_clock` — the row's wall, else the filename-class date, else the earliest fs time in the display zone (unindexed files). - `/memories` items and `/photos/gps-summary` photos: `row_wall_clock`. - `get_all_with_gps` returns full rows instead of a 7-tuple that dropped `date_taken_source`, which unconverted rows need. - `date_view::owner_display_zone` resolves prefs -> app default per request. Legacy fields are untouched, so current clients see byte-identical responses (additive; safe to deploy ahead of the client flip, per #120). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! Read-side views of the true-instant date contract (ADR-0001).
|
||
//!
|
||
//! [`crate::date_resolver`] is the ingest-side counterpart: it *writes* the
|
||
//! `(date_utc, camera_offset_minutes, date_taken_tz_source)` triple. This
|
||
//! module is what *reads* it. For a row — converted or not yet — it answers:
|
||
//!
|
||
//! 1. **What true instant does the row name?** — [`row_true_instant`].
|
||
//! Anchors time-window queries (SMS messages, location history, calendar
|
||
//! events) with zero offset arithmetic: the window is centered on the
|
||
//! instant, never on a wall clock.
|
||
//! 2. **What wall clock does the owner see?** — [`row_display_wall`].
|
||
//! The date insight prompts tell the model (camera wall clock when the
|
||
//! row carries an offset, display-zone rendering when it doesn't). Must
|
||
//! equal the wall the metadata endpoint reports, so prompt and UI agree.
|
||
//! 3. **Which owner day does the row land on?** — [`row_display_day`].
|
||
//! The grouping rule for memories buckets and reels: a photo taken in
|
||
//! Japan at 21:00 JST lands in the *owner's* day, not the camera's.
|
||
//!
|
||
//! Converted rows read the new triple directly. Unconverted rows (the
|
||
//! `backfill_utc_dates` drain has not reached them yet) fall back to the
|
||
//! legacy `date_taken` under its per-source convention (ADR-0001):
|
||
//!
|
||
//! | source | legacy holds |
|
||
//! |---|---|
|
||
//! | `exif` | camera wall clock, reinterpreted as UTC |
|
||
//! | `exiftool` (video) | the container's UTC-rendered naive, rendered in the server zone |
|
||
//! | `exiftool` (image) | camera wall clock, rendered in the server zone |
|
||
//! | `filename` (wall patterns) | wall clock, reinterpreted as UTC |
|
||
//! | `filename` (unix-timestamp) | a true instant |
|
||
//! | `fs_time` | a true instant |
|
||
//! | `manual` | the display-zone wall the operator picked, reinterpreted as UTC |
|
||
//!
|
||
//! so mixed rows mid-drain still group into the right day and the insight
|
||
//! prompts stay correct row-by-row as the drain converts.
