Owner ruling (2026-10-08): "{now} should be per file, {start} the
capture's start — that's the behavior I had intuited from both
existing, so if they're the same today by design that's even more
confusing than I expected." resolve_run_path picked one Local::now()
per run and LogWriter reused that base for every split; the panel's
preview only re-asked the host when a template, the project, the
logger's name, or the capture's start changed. So {now} read as a
timestamp frozen at the run's start, identical to {start} whenever a
capture had no wall-clock anchor of its own.

LogWriter now opens through a FileNamer closure — called once to
open the run and again at every roll — instead of holding a fixed
base. The production namer (make_run_namer) resolves the folder
once, rooted and read before the run starts (nothing in a folder
template has reason to differ file to file), closes over the capture's
wall-clock start once, and resolves the file template fresh against
Local::now() on every call. {start} therefore stays the capture's
start across every split; {now} names each file's own creation. The
collision rule is unchanged and is now the only reason a suffix
appears: a resolved name already on disk — because the template has no
{now} at all, or a {now} pattern repeated within its own precision
— takes the next -002, -003… the same way at the run's first file
and at every later split (first_free_part/split_path, now always
scanned from part 1 since each open supplies its own fresh base rather
than a running part counter).

The logger panel's preview ticks once a second while mounted and a
template holds {now} — the interval DateTimePatternEditor already
runs for the date_time_pattern setting — skipped entirely when
neither template carries the token, so an unaffected logger issues no
extra IPC.

Docs: export_template.rs's {now} doc, logger.rs's module doc and
the LogWriter / FileNamer / make_run_namer rustdoc, README's
logger section (per-file {now}, the unchanged {start}, the
collision rule, the preview tick). No ADR states the logger
run-naming rule — ADR 0062 covers only the date-pattern notation, not
when a logger evaluates it — so none is amended.

Verified: cargo test -p cannet-gui (1449 passed, two new — a roll
resolves the file template from its own fresh instant; {start} stays
fixed across a roll while {now} advances), cargo clippy -p cannet-gui --all-targets -- -D warnings, cargo fmt --all -- --check,
rustdoc -D warnings; pnpm --dir apps/gui test (3875 passed, three
new on the preview tick), pnpm --dir apps/gui build; pnpm --dir apps/gui tauri build --no-bundle (release host, runs). Python lanes
skipped — the diff cannot reach them.
