WalkthroughThe pull request expands the book with developer guidance, backend and event-system references, export-format documentation, and TUI feature guides. It also updates navigation and existing feature descriptions. ChangesDocumentation updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This PR adds book content, but the current documentation includes a malformed NDJSON example that can break parsers and TUI configuration examples that users would copy yet have no effect because of invalid names or nesting. These bounded correctness issues should be fixed before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Inline comments:
In `@book/dev/architecture.md`:
- Around line 38-40: Update the PendingRequest channel descriptions to document
the complete ptrace control contract: in book/dev/architecture.md lines 38-40
and book/dev/event-system.md line 13, replace the breakpoint-only wording with
ptrace control wording or explicitly list breakpoint requests,
seccomp-optimization suspension, and tracer termination.
- Around line 12-17: Keep the dedicated frontend crate list at exactly three
entries by removing the list marker from the log-frontend note and placing that
sentence as a standalone paragraph immediately after the list.
In `@book/features.md`:
- Around line 19-20: Update the Collect overview sentence to state that it
writes JSON, NDJSON, or a Perfetto trace for later analysis, matching the
dispatched ExportFormat::JsonStream behavior.
In `@book/features/collect.md`:
- Line 9: Resolve the broken Perfetto documentation link in the collect feature
documentation by either adding the required content to the referenced Perfetto
page or removing the link until that page is documented.
In `@book/features/collect/json.md`:
- Around line 16-17: Update the JSON/NDJSON examples in the collect
documentation so each fenced payload contains only parseable exporter data:
capture exporter output with --output <file> before displaying it, or move the
complete terminal transcript to a console block and keep separate clean JSON and
NDJSON payload blocks.
- Line 48: Update the NDJSON serialization in the exporter implementation, using
the relevant function in crates/tracexec-exporter-json/src/lib.rs, to emit a
newline after the baseline record before the first event. Add a regression test
that verifies the baseline and first event are separate lines, then regenerate
the JSON example so it reflects the corrected delimiter.
In `@book/features/tui/copy.md`:
- Around line 24-32: Update the fenced code example in the copy documentation to
specify the text language tag, using the existing output content unchanged.
In `@book/features/tui/keys.md`:
- Line 5: Update the sentence introducing the TUI key bindings to use the plural
verb “are” instead of “is,” preserving the existing wording and inline
`tui.keys` reference.
In `@book/features/tui/term.md`:
- Line 3: Update the sentence describing the default terminal behavior to use
the hyphenated compound modifier “user-specified command.”
In `@book/features/tui/theme.md`:
- Line 46: Update the theme documentation examples to use the accepted
kebab-case keys: replace partial-output with partial-ok and underline_color with
underline-color so ThemeSpec and StyleSpec settings are recognized.
- Line 66: Update the style-attribute section wording: change “an UI element” to
“a UI element” and correct the misspelling of “integer” at the referenced
attribute description.
- Around line 103-110: Add the required [tui] table declaration before the theme
TOML example so theme is nested under Config.tui.theme rather than placed at the
top level.

Use the accepted kebab-case theme keys.
The example uses partial-output, but ThemeSpec defines partial_ok, so the accepted key is partial-ok. The attribute list uses underline_color, but StyleSpec also uses kebab-case, so the key is underline-color. With the current names, both settings are treated as unknown and ignored.

Show the required [tui] table.
theme belongs to Config.tui.theme. Readers who copy this standalone example will place theme at the top level, so the setting will not populate the TUI configuration. Add [tui] before the example. (raw.githubusercontent.com)
