The previous shape guessed the character from `event.key` on keydown, re-emitted
it, and then tried to suppress a late canonical copy with a 250 ms
character-keyed dedupe. Review found three defects in that, all reproducible:
the dedupe matched on the character alone with nothing scoping a candidate to
the keydown that created it, so the same character typed twice inside the window
had its second, real byte swallowed; anything whose committed text differed from
`event.key` (Enter, IME punctuation) was delivered twice, because the dedupe
could never match it; and the trigger ignored `key === 'Unidentified'`, which is
what a soft keyboard reports, so it may never have fired where it was needed.
The input event already carries the committed text in `ev.data` — exactly what
xterm itself would have forwarded — so nothing has to be guessed. The controller
now only decides WHETHER to forward, by asking whether xterm produced canonical
data since the keydown that began the keystroke. No character-keyed matching
survives, so the first two defects are structurally impossible rather than
defended against, and nothing reads `key`/`keyCode`, so the third cannot recur.
Three details are load-bearing and each has a test that fails without it:
- The "did xterm speak?" snapshot is taken at KEYDOWN, not at the input event.
`_keyPress` emits and sets `_keyPressHandled` before `input` fires, so a
snapshot read at input time already contains that emission, reads it as
silence, and delivers the character twice.
- Our `input` listener is registered with `capture: true`. The target is visited
twice in the event path, so a capture listener calling `stopPropagation()`
stops later BUBBLE listeners on that same target; xterm's `cancel()` runs
exactly in the branch where it handled the input, so on bubble we would never
observe handled events, and whether we observed them at all would hang off
`options.cancelEvents`. Measured in jsdom and headless chromium; the table is
in the module header.
- Enter is deliberately no longer special-cased. That mapping is what made the
committed text differ from the re-emitted value in the first place.
The scope is also narrower than the old name suggests, and the browser test now
proves it rather than assuming it. For a keydown that reports keyCode 229 xterm
ALREADY self-rescues, via `CompositionHelper._handleAnyTextareaChanges()`
diffing the helper textarea on a 0 ms timer. A test asserting "we recovered it"
there passes while xterm does all the work, so the browser tests assert WHO
delivered the byte: zero canonical emissions for the genuinely orphaned case,
exactly one delivery for the case xterm rescues itself.
Also addresses review notes: the module gains an `@fileoverview` with
`@dependency`/`@loadorder` and an entry in the load-order list and module
inventory, and the wiring test moves out of the Ctrl+C smart-copy file into its
own. The keydown hook deliberately still runs for every key event rather than
moving behind the 229 gate: gating it would reinstate exactly the blindness
described above, and it is now a single counter assignment.
Maintainer tooling in scripts/pr-bot/: a daemon (systemd user unit
codeman-pr-bot) that lists open PRs with gh, reviews each head commit once in
a Codeman claude session (`prbot-<n>`) running in a private `git clone
--shared`, and sends the verdict, ranked findings, checks and a recommendation
to Telegram with action buttons. Merge, close, post-comment and approve-CI
happen only from a Telegram command or button plus a confirmation tap; the
bot never writes to GitHub on its own. The Telegram token and chat id come
from the existing notifier bot's env file.
Verified live: three PRs reviewed end to end (383, 363, 368), reports
delivered with buttons, reviewer sessions on the pinned model. Findings
along the way, each fixed and documented: a linked worktree inherits the
main checkout's model pin (hence the shared clone), undici's 5-minute header
timeout cut off the first review, gh was missing from the service PATH, and
the periodic scan orphaned an in-flight review's record.
typecheck/lint/format now cover scripts/pr-bot; tests in
test/pr-bot-{report,state,commands}.test.ts; guide in docs/pr-bot.md.

`npm test` ran config/vitest.config.ts, which includes the browser, visual and
perf suites. On any machine without chromium, a free port and per-machine PNG
baselines that fails ~87 tests on a clean master, so the repo's most obvious
command could not be used as a pass/fail signal. The workaround had spread into
four docs as "never run bare `npm test`" warnings.
`npm test` now runs config/vitest.ci.config.ts — byte-for-byte what CI runs — so
local green means CI green. Verified: 264 files, 5248 tests, exit 0.
The suites it leaves out are not abandoned; each has a command:
test:browser 5 Playwright files (chromium + a live server; codex-predictive-echo
also needs a real codex binary)
test:mobile unchanged — the above plus per-machine PNG baselines
test:perf 2 wall-clock benchmarks; need an otherwise idle machine
test:all the old everything-behaviour, kept reachable
test:ci is untouched (CI still calls it). test:watch and test:coverage follow
test onto the gate's config.
The more important half is the hole this closes. The exclusion list lived as
literals in one config and pointed one way only: a file excluded from CI and
added to no runner would be tested by NOTHING, silently, with every command
still green — vitest counts "no files matched a filter" as success. That is the
same shape as the #279/#280 blind spot already documented in CLAUDE.md.
So the globs moved to config/test-suites.ts, one array per REASON a suite cannot
run in CI, and all three configs derive from it. test/test-suite-partition.test.ts
then checks the arithmetic against the files on disk: it fails if any test file
is reachable by no runner, or by two. Confirmed it fires by orphaning a file and
watching it name it. The partition is exact today:
gate 264 + browser 5 + perf 2 + mobile 9 = 280 = every *.test.ts in the repo
⚠️ One sharp edge, deliberate and documented: a file filter must match its
runner. `npm test -- test/mobile/keyboard.test.ts` now matches nothing and exits
GREEN having run zero tests, because the gate's config excludes that path.
CLAUDE.md recommended exactly that command in the on-screen-keyboard note; that
line now says `npm run test:mobile -- <file>`, and the Testing section calls out
the trap, since a green run of zero tests is worse than a red one.
Docs synced: CLAUDE.md, AGENTS.md, .github/CONTRIBUTING.md, README.md,
README.zh-CN.md, and two ci.yml comments that claimed only test/mobile/** was
excluded — it is three suites, and 5 Playwright files rather than 3.

Out-of-process lab server (VITEST markers stripped so tmux/codex are real),
CODEMAN_INSTANCE=codexlab on port 3222, throwaway CODEX_HOME with a fake
key. Ten scenarios: bundle smoke, predict+converge typing, the #218 arrow
retest (submitted text exact), the #222 live picker, the #219 paste order,
the #220 wrap, the trust-modal ghost eliminator, the localEchoEnabled kill
switch, the end-to-end byte-identity trace (predictor active vs null), and
a display-delayed 300ms-RTT run pinning instant spans with exact pixel
geometry plus arrow-edit correctness under lag.
Live-TUI hardening learned the hard way: codex Ctrl+U kills only to line
start (End first), a fake-key submit leaves a Reconnecting loop that can
kill codex seconds later (retry-cancel + composer stability probe; the
submitting scenario runs after all composer-state ones), and typing must
wait for the predictWhen gate itself, not merely a rendered composer.
CI-excluded like the other Playwright suites; skips cleanly when codex is
not installed.

Closes#211. Copying from the terminal only worked through the browser
context menu, because xterm turns Ctrl+C into 0x03 and cancels the keydown,
so the muscle-memory copy failed silently and read as "no copy-paste at all".
With a selection, Ctrl+C now copies it, toasts, clears the selection and
sends nothing to the PTY. With no selection it falls through unchanged, so
the interrupt is intact. Ctrl+Shift+C is an explicit copy chord that never
falls through: an explicit copy that interrupts a running agent because the
selection happened to be empty would be a footgun.
Three details that keep the interrupt safe:
- The decision lives in attachCustomKeyEventHandler (terminal-ui.js) and the
no-selection path returns true WITHOUT preventDefault. xterm calls the
custom handler before its own cancel(), so returning false alone does not
cancel the event; the copy path therefore calls preventDefault explicitly,
or the browser would run its native copy on top of ours.
- copy-selection is a full registry entry (rebindable and disableable in App
Settings) whose action is deliberately absent from SHORTCUT_ACTIONS, the
same trick command-palette uses: the generic capture loop preventDefaults
every match it dispatches, which would cost the user the interrupt key.
- The gate is keydown-only, since the custom handler also runs for keypress
and keyup.
Copy goes through _copyText (Clipboard API, then hidden-textarea +
execCommand) rather than raw navigator.clipboard, because install.sh's LAN
option serves plain HTTP where navigator.clipboard is undefined; the
fallback steals focus, so the terminal is refocused afterwards.
Tests: test/terminal-copy-selection.test.ts pins the gate and the
SHORTCUT_ACTIONS invariant; test/terminal-copy-shortcut.test.ts drives real
key presses in chromium and asserts on the clipboard plus the bytes xterm
emitted (browser-driven, so excluded from test:ci like the other Playwright
suites). Verified manually on an isolated beta instance before landing.

Continues trimming the repo root so the README is reached with less scrolling.
Root files: 19 -> 15 across both passes.
- knip.json -> config/knip.json, joining eslint.config.js and the vitest
configs. `npm run knip` now passes --config explicitly. Verified by A/B: the
run from the new location produces byte-identical findings and the same five
configuration hints as from the root, so knip resolves its globs relative to
cwd rather than the config file. Those hints are pre-existing, not caused by
the move.
- .prettierrc -> the "prettier" key in package.json, a config source Prettier
reads natively, so editor format-on-save keeps working with no --config flag
anywhere. Verified live: `npm run format:check` still passes across src/**,
which it could not if the config had been lost (Prettier's defaults are
double quotes at 80 columns and would flag nearly every file).
.prettierignore deliberately stays at the root: Prettier resolves it relative
to cwd, so moving it would require threading --ignore-path through every
script and would break editor integration.
Everything else in the root is load-bearing: .editorconfig (walks up from the
edited file), .nvmrc/.npmrc (read from the project root), tsconfig.json (bare
`tsc` discovers it), LICENSE (GitHub license detection), install.sh (its raw
URL is the published one-liner in the README and cannot move without breaking
every copy in the wild), plus the five documented .md files.

- CI: add a 'test' job running the unit suite via config/vitest.ci.config.ts. Excludes browser (Playwright/chromium) and perf tests (timing-flaky), like the existing test/mobile suite. Safe in CI: TmuxManager no-ops shell commands under VITEST (test/setup.ts).
- Add scripts/check-frontend-syntax.mjs (node --check on src/web/public/*.js), wired into the lint job — catches a class of frontend SyntaxError that passes lint today (lint globs only TS).
- Add test/security-regression.test.ts (wired Host/Origin guard, self-update CSRF, CSP/security headers, text/plain raw body, WS anti-CSWSH) + test/sse-registry-parity.test.ts (backend<->frontend SSE registry parity).
- Green pre-existing test debt surfaced by the new gate: stale 'Session not found' asserts -> 'not found' substring; drop tests for removed helpers (isError now internal; createSuccessResponse deleted); file-stream-manager: mock realpathSync + fix stale /tmp assertion; sse-subscription-filter: lifecycle events broadcast to all clients (only terminal stream filtered); session.test.ts: mkdir /tmp/test; skip one interactive-respawn test needing a real PTY (covered by respawn-controller.test.ts).
- Full non-mobile suite verified green locally (2680 passed, 12 skipped).
