An empty read window (byte cap below the first selected line: `lines: []`
with `totalLines > 0`) dropped `offset` from the persisted presentation
meta, so a replayed read card could not report where the window starts or
where a continuation resumes. Carry `offset` on `FsReadMeta`,
`ReadResultView`, and the `presentationMeta` projection, and validate it in
`readMetaFromMeta` (1-based integer; the first line number may not fall
below it). Re-record the ACP fixtures and the cordis api catalog.
Also correct the Note's `parallel-file-reads` golden path
(examples/tui-agent -> apps/cli) and record the pre-card replay-degradation
tradeoff in the Decision section.
The read tool now projects presentationMeta ({path, lines, totalLines}) onto
its tool/result, so every scenario with a read call carries that meta; the
cordis-inspect snapshot's embedded type surface gains ReadResultView /
ReadFileLine / the widened ToolResultView. Model-facing text is unchanged.
Refreshed keyless via test:snapshot:refresh. The unrelated goal.snapshot
SQLite ExperimentalWarning failure is pre-existing on clean master.
