feat(tui): add focused transcript actions

[wuisabel-gif]

Summary

Addresses the approved focused slice of #5551.

When the transcript is focused and the composer is empty, the current focused block now supports:

• y — copy canonical block content;
• Y — copy the rendered metadata/receipt view;
• Enter — open the block in a fullscreen readable pager;
• r — open the existing raw detail view.

The implementation reuses the existing focused-cell heuristic, clipboard seam, pager surfaces, and raw-detail renderer. The Tasks rail y/Y shortcuts remain ahead of transcript handling and retain their existing behavior.

docs/KEYBINDINGS.md and the changelog are updated.

Tests

Passed locally:

• cargo fmt --all -- --check
• git diff --check
• cargo test -p codewhale-tui --lib 'tui::ui::activity_detail' --locked (11 passed)
• cargo test -p codewhale-tui --lib 'tui::ui::tests' --locked (667 passed)
• CARGO_INCREMENTAL=0 cargo clippy -p codewhale-tui --all-targets --locked -- -D warnings

Coverage includes focused pager/copy targeting, canonical content copy, metadata copy, existing raw-detail behavior, and the full UI event-loop test module.

CI diagnosis for the failed matrix jobs:

• Ubuntu and macOS both failed the same pre-existing plugin_e2e_acceptance::plugin_toml_binary_lifecycle_skill_and_stdio_mcp_acceptance test at plugin_e2e_acceptance.rs:676: /plugin trust demo was not visible within the 3-second PTY wait. The visible frame was still the plugin detail page (State: disabled, Trust: not-reviewed). The transcript-action diff does not touch the plugin test or plugin command path.
• Windows failed the two existing absolute-path tests associated with Read-only inspection children reject in-workspace absolute git -C at execute time #5595:
  • tools::shell::tests::readonly_operands_are_workspace_bounded_and_symlink_aware
  • tools::subagent::tests::read_only_inspection_roles_execute_pwd_and_absolute_git_log
    Both reject the Windows \\?\C:\... canonical path form before execution. The transcript-action diff does not touch shell safety, subagent posture, or path handling.

All 667 tui::ui::tests and 11 activity-detail tests passed locally, and strict TUI Clippy passed. The failed CI jobs are baseline failures outside this PR's changed files. I attempted to rerun the failed jobs, but GitHub requires repository admin rights for reruns; a maintainer can rerun them if desired.

Holding this PR — not merging tonight.

CI is red on all three Test jobs, and the failures are outside this diff:

• ubuntu/mac: plugin_e2e_acceptance::plugin_toml_binary_lifecycle_skill_and_stdio_mcp_acceptance
• windows: tools::shell::tests::readonly_operands_are_workspace_bounded_and_symlink_aware and tools::subagent::tests::read_only_inspection_roles_execute_pwd_and_absolute_git_log

This PR is the focused-transcript-actions slice for #5551 (6 files). Once those suite failures are green on the branch (or shown to be pre-existing on main and waived), we can take it.

[Hmbown]

Thanks for this — the feature is a good idea and the y / Y / r / Enter set is the right shape. I dug through the CI logs so you don't have to. There are two separate stories in the red checks, and only one of them is yours.

Windows: not your fault, ignore it

Test (windows-latest) fails on exactly two tests:

FAIL codewhale-tui tools::shell::tests::readonly_operands_are_workspace_bounded_and_symlink_aware
FAIL codewhale-tui tools::subagent::tests::read_only_inspection_roles_execute_pwd_and_absolute_git_log

Those two fail on main itself and on every open PR right now (Windows verbatim-path \\?\C:\... operands getting mangled by a POSIX word splitter). #5610 fixes them. Nothing for you to do — rebasing won't help until that lands.

Ubuntu + macOS: this one is real, and it's a genuine user-facing bug

One test fails on both, and it's green on main:

FAIL (12898/13524) codewhale-tui::cucumber
  plugin_e2e_acceptance::plugin_toml_binary_lifecycle_skill_and_stdio_mcp_acceptance

panicked at crates/tui/tests/cucumber/plugin_e2e_acceptance.rs:676:9:
typed command not visible: "/plugin trust demo"
visible head:
  1 |   Note ───────────────────────────────────
  ...
  8 |   Version: 1\.0\.0

Read that dump closely: the pager is open, showing the previous /plugin show demo cell, with markdown-escaped text. The r in t-r-ust fired your new r binding.

Root cause is ordering. Your new block sits at event_loop.rs:4302, but the paste-burst flush is at event_loop.rs:4488 — 186 lines later. While a keystroke burst is being assembled, apply_paste_burst_retro_capture (crates/tui/src/tui/paste.rs:139) does:

app.input.replace_range(grab.start_byte..cursor_byte, "");

It pulls already-typed characters back out of the composer into the burst buffer. So app.input.is_empty() is transiently true in the middle of a typed word, and your block sees that state before any flush happens. Fast typing /plugin trust demo loses the r into the pager. This isn't test-only flakiness — burst detection stays active on any terminal until a real bracketed-paste event is seen, so fast typists would hit it.

There's a second, quieter issue: detail_target_cell_index() ends with .or_else(|| app.virtual_cell_count().checked_sub(1)) (activity_detail.rs:580), so it returns Some whenever the transcript has any cell. It isn't a focus check, which means the bindings are effectively always armed rather than "focused".

Suggested fix

The codebase already has the precedent you want — handle_transcript_space at event_loop.rs:111:

crate::tui::paste_burst::FlushResult::Typed(' ')
    if app.input.is_empty() && handle_transcript_space(app) => { true }

Move y / Y / r into flush_paste_burst_before_composer as sibling arms and delete the block at 4302. This is essential rather than cosmetic: PasteBurst::on_plain_char returns RetainFirstChar even for a single keystroke (paste_burst.rs:76), holding it as pending_first_char and re-emitting it later as FlushResult::Typed(c). A plain r therefore never arrives at the match key.code at 4575 as a KeyCode::Char event — so putting the arms only there would silently make the feature dead for typed keys.

Two follow-ons worth doing while you're in there:

• Tighten the guard to real transcript focus (e.g. app.viewport.transcript_selection, the way the neighbouring Enter / open_pager_for_selection arm at 4576 does) instead of detail_target_cell_index(app).is_some().
• Add an event-loop-level regression test that feeds a word containing r/y as one fast burst and asserts app.input ends up with the full literal string and app.view_stack.is_empty(). Your existing focused_pager_and_metadata_copy_use_the_same_cell_target calls the functions directly, so it can't catch an ordering bug like this.

The Enter binding you added at 4602 is fine as-is — it's inside the match key.code after the flush, so it already sees the true composer state.

@Hmbown Thank you so much, will fix the bugs accordingly.

[wuisabel-gif]

Follow-up fix pushed in 3b99f4c97 based on the CI diagnosis:

• removed the pre-flush app.input.is_empty() transcript-action block;
• moved y/Y/r handling into flush_paste_burst_before_composer, alongside the existing typed-space action;
• required an active transcript selection instead of relying on detail_target_cell_index()'s latest-cell fallback;
• added typed_command_burst_keeps_r_and_y_out_of_transcript_actions, which feeds /plugin trust demo through the paste-burst path and asserts the full command remains in the composer with no pager opened.

Local verification after the fix:

• focused regression: pass;
• full tui::ui::tests: pass;
• strict all-target TUI Clippy: pass;
• format and diff checks: pass.

@wuisabel-gif — you were right, and we owe you a straight account of what happened here.

What went wrong on our side

Hunter approved this slice for you on #5551 on 08-24. Then, at 02:04 on 08-25, we landed our own implementation of the same slice as 32baa175f — 90 minutes before you opened this PR at 03:34. You wrote a duplicate because we built the thing we had asked you to build and did not tell you. That is entirely our mistake, not a problem with your PR, and it is the reason this sat without a real review for a day.

Your finding was real — and our version had the bug too

The internal read on this PR was that your gate (detail_target_cell_index().is_some()) was the defect and that our selection gate was the answer. That was wrong, and your CI diagnosis is what exposed it.

You correctly identified that the r in /plugin t-r-ust fired the binding and broke plugin_toml_binary_lifecycle_skill_and_stdio_mcp_acceptance on ubuntu and macOS. Our selection gate refuses your exact reproduction — but the same keystroke is still stolen by a different route. A transcript selection made with the mouse is never cleared by typing (only by resize, click-away, or an explicit command). So with a selection standing, the first y/Y/r of a typed message is consumed as an action while app.input still reads empty.

Typing review this left eview this in the composer and opened a pager. On our code, not yours.

We wrote your scenario as a test against 32baa175f and it failed:

---- typing_burst_keeps_its_first_char_out_of_block_actions stdout ----
panicked at crates/tui/src/tui/ui/activity_detail.rs:2167:9:
a keystroke inside a typing burst must stay composer input

What landed

a5ff66d80 on the 0.9.12 integration branch, with you as co-author. It applies your insight — defer to an in-flight paste/typing burst — to our wiring, plus two regression tests that are yours in substance:

• typing_burst_keeps_its_first_char_out_of_block_actions — pins the mechanism, and pins that a standing selection still claims the key once the burst settles, so the feature is unchanged for its intended use.
• typed_plugin_command_survives_a_standing_selection — walks the literal /plugin trust demo string you reproduced.

Gates: rustfmt clean, clippy clean, 11391 passed / 0 failed / 13 ignored.

This PR

Closing it, because 32baa175f + a5ff66d80 now cover everything in it — content copy, metadata copy, fullscreen pager, raw detail, KEYBINDINGS docs — and there is no remaining delta to merge. Closing it is bookkeeping, not a rejection: the part of this PR that we did not already have is the part that mattered, and it is in.

Also, for the record on the red CI you were chasing: the two Windows failures were never yours. They fail on main and on every open PR, and #5610 fixed them (32a6bac84 on our branch).

Thank you for pushing 3b99f4c97 instead of walking away when the review was slow. That fix commit is what made us look again.

@wuisabel-gif — honest correction, and we still owe you the landing.

This PR was closed on 08-25 as "already on the 0.9.12 integration branch" (32baa175f + a5ff66d80, you as co-author on the typing-burst fix). I just checked current origin/main (a96ea6cb). Those commits are not ancestors of main. The focused transcript actions are not there:

• docs/KEYBINDINGS.md Transcript section has no y / Y / Enter / r block actions
• no typing_burst_keeps_its_first_char_out_of_transcript_actions / typed_plugin_command_survives_a_standing_selection
• composer-empty y/Y still go to Tasks-rail / other owners, not a focused transcript cell

Closing this GitHub PR as "integrated" was bookkeeping against a stale integration head, not a merge to main. Sorry. The work is yours, including the paste-burst ordering catch that made the feature safe.

Rescue plan (not asking you to rebase the fork branch): local worktree cw-pr5608-rescue-20260827, three commits already on top of current origin/main, authorship preserved:

• e27df97e7 feat(tui): add focused transcript actions — Isabel Wu
• dcac93bab fix(tui): keep transcript shortcuts out of paste bursts — Isabel Wu
• 14fb762df test(tui): keep transcript actions behind settled input — maintainer test follow-through

That branch is not yet on origin as a PR. Another lane owns opening/merging it. I am not reopening this fork PR: the head is stale, and the rescue is the landing vehicle. I am also not merging from this lane.

Nothing for you to re-send unless you want to. Credit stays with you.

[Hmbown]

Re-landing this on current main as #5652.

#5608 was closed as already integrated on the 0.9.12 integration branch, but the work never reached origin/main. Authorship of the feature and paste-burst fix commits is preserved for @wuisabel-gif.

[Hmbown]

Landed on main via #5652 (aed9f5c79).
