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.
Address the review of the search render card:
- The search result view carries no `content`: it was a no-op for every
consumer and serialized the whole search text twice. A UI without a search
card falls back to the raw tool/result content; the TUI stays byte-identical
to the pre-search-card generic fallback.
- Bound the serialized presentationMeta with a configurable searchMetaMaxBytes
(default 64 KiB): the inline item cap does not bound bytes, and spill-policy
only shrinks content, never meta. capMetaBytes drops trailing groups/paths.
- Share one retention pass (retainGrepMatches/retainGlobPaths in search-core)
between the model-facing render and the meta projection; remove the second
cap/preview implementation and the presentation<->grep module cycle by
moving GrepMatch/previewLine to search-core.
- Rename the result-view discriminant kind -> shape so it no longer collides
with GenericCallView.kind (ToolCallKind, whose values include 'search').
- Narrow the entry export surface to consumed symbols.
- Sync the three bilingual ToolResultView doc pairs and the Agent Note pair;
document the deliberate empty-card acceptance vs diffsFromMeta.
- Regenerate config/tool/cordis catalogs for the new config field.
Address the code-review bot findings on the web result card:
- web_fetch's card truncated now derives from the shared renderFetchOutput
helper, matching the effective truncation the model-facing text reflects
(provider cap, source cut, or output cap), instead of the provider-only flag.
- Drop the redundant content copy from both web result views; a UI without the
web capability falls back to the raw tool/result content. Narrow the TUI
transcript view.content access accordingly.
- Set the result-state title from the call args (query/url) so a window-
truncated replay keeps a title.
- Project meta from the seam result types rather than hand-rolled value types.
- Sync the card vocabulary across core tools README, docs/core-data-structures,
the adding-a-tool cookbook, and the tool-web package README (both languages,
re-recorded pairings); regenerate the cordis api-catalog and cordis-inspect
snapshot; revise the Agent Note.
readMetaFromMeta narrows the opaque persisted meta boundary, so beyond
shape it now rejects replayed JSON that is well-typed but semantically
invalid: line numbers must be 1-based integers, totalLines a non-negative
integer, and line numbers must strictly increase without exceeding
totalLines. Any violation declines to the generic fallback.
Sync the public ToolResultView contract across the core/tools and
tool-fs READMEs and docs/core-data-structures/tools for the fourth
result-view member and the ReadFileLine vocabulary, and expand the
Agent Note Testing section with the new rejection paths and the snapshot
evidence this PR carries.
web_search and web_fetch returned only model-facing text, whose markdown source
list is lossy (title-or-hostname label, snippet and date concatenated), so a
client could not recover the structured sources. Add a card:'web' result view
with a kind discriminant ('search' carrying structured sources + answer +
truncated, 'fetch' carrying url + statusCode + truncated), projected through
each tool's output.presentationMeta and read back in presentResult. A UI
without the web card falls back to content; the TUI is unchanged. The web
consumer is a follow-up.
grep and glob returned only model-facing text; the structured matches/paths
never reached the client. Add a card:'search' result view with a kind
discriminant ('matches' grouped by file for grep, 'paths' for glob), projected
through each tool's output.presentationMeta and read back in presentResult. The
projections re-apply the same inline cap and per-line budget as the render text
and report total + truncated, so a UI never presents a capped page as complete.
A UI without the search card falls back to content; the TUI is unchanged. The
web consumer is a follow-up.
The read tool's result carries structured numbered lines, but only the
model-facing envelope text reached the client. Add a card:'read' result view
(ReadResultView) projecting {path, lines, totalLines, lang} through the tool's
output.presentationMeta so presentResult reproduces it on live and replay
paths; the pending call stays a generic read card. A UI without the read
capability falls back to the envelope-stripped content, so the TUI is
unchanged. The web consumer that renders the line-numbered view is a follow-up.
Adds direct coverage for `Session.requestContext()`: undefined before any
record, folding a seeded log on first read (the watermark starts at 0 with the
seed already in the log, so a first read must consume all of it), incremental
advance across appends, a batch appended between two reads, and the frozen
return that keeps a reader from desyncing later dedup comparisons.
The turn-enclosure assertion goes in the invariant spec rather than beside the
fold tests, because enclosure is enforced by the opt-in invariant companion
plugin and not by `append` itself. Asserting it on a bare Session would have
been a test that passes for the wrong reason.
The chat stats line took its token totals from the loaded conversation nodes,
so paging changed them and compaction erased the billing behind replaced
content. It also had no way to show context occupancy: the numerator and
capacity never reached the browser.
Both now come from token-meter session projections read through the standard
useProjection seat. Window nodes keep supplying turn and step counts plus LLM
and tool wall times, which are correctly window-scoped facts about what is on
screen; accounting no longer comes from there.
`tokenUsage` supplies billing and cache hit. `contextPressure` supplies
occupancy, pairing the newest provider-reported prompt size with the newest
capacity recorded by `request/context`. Deployments without token-meter drop
the token groups; a route whose adapter advertises no capacity drops the
occupancy group rather than rendering a placeholder.
Occupancy is deliberately approximate: the numerator and capacity are
independent last-wins fields, not one atomic request observation, so switching
models pairs a fresh capacity with the prior route's pressure until the next
request reports usage. It is a user-facing reference figure that nothing in the
harness makes decisions from, and it matches how the TUI status line has always
computed occupancy. The Agent Note and token-meter README state this as a
decision, including why the atomic alternative was implemented and rejected, so
it is not re-litigated as a defect.
Snapshot delta is one added `Context N% of 128K` segment across eight web
goldens; the preceding commit absorbed master's pre-existing golden drift.
