Summary

The notify system (terminal bell + OSC-9 desktop notification on permission prompts and completion) already existed, but it was silent by default and undiscoverable: the resolver left notify.mode/focusMode empty unless the user hand-edited ~/.config/zero/config.json, and there was no UI surface to find or change the setting. A first-run user sees a permission prompt with no alert and reasonably concludes permission prompts are broken.

This PR makes the alert work out of the box and adds two discoverable surfaces, all going through one writer so they stay in lockstep:

  • Resolver default: when the notify block is missing or empty, fall back to mode=both, focusMode=unfocused (internal/config/resolver.go). Users who explicitly set off or any other value are unaffected.
  • /notify slash command (TUI): popup picker with four (mode, focus) pairs, mirroring the existing /theme picker pattern (internal/tui/notify_select.go, internal/tui/picker.go). Explicit choices persist to user config. A mode-only argument preserves the existing focus rule.
  • zero config notify (CLI): print current values, or update with --mode <off|bell|notify|both> --focus <unfocused|always|focused>, --reset to clear, --json for scripts (internal/cli/config_notify.go).
  • config.SetNotify writer: read-modify-atomic-write via the existing writeConfigFile helper, validating against the same vocabulary the resolver accepts (internal/config/writer.go).

Notes on two changes that are downstream of the default, not scope creep:

  • effectiveTUINotifyMode (empty → ModeBoth instead of ModeOff) exists so the TUI's notifier and the resolver agree on the default — required by the first bullet of the issue.
  • internal/cli/exec_test.go adds "notify": {"mode": "off"} to one test's fixture because that test asserted empty stderr, which the old silent default implicitly provided.

The notify system existed but was silent unless the user hand-edited
config.json, with no UI surface to discover or change it.

- resolver: fall back to mode=both, focusMode=unfocused when the notify
  block is missing or empty (Fixes Gitlawb#579)
- tui: add /notify slash command with popup picker, mirroring /theme;
  explicit choices persist via config.SetNotify
- cli: add `zero config notify` to read/update/reset the preference
  (--mode, --focus, --reset, --json)
- config: add SetNotify writer using the existing atomic-write helper,
  validating against the same vocab the resolver accepts

The TUI effectiveTUINotifyMode default (empty -> both) now matches the
resolver. exec_test.go seeds notify.mode=off where a test asserted
silent stderr, which the old empty-default implicitly provided.

Walkthrough

This change adds notification defaults and persistent configuration support. It exposes notification settings through zero config notify and the TUI /notify command, including validation, reset behavior, picker selection, JSON output, live updates, and regression coverage.

Changes

Notification preferences

Layer / File(s) Summary
Notification defaults and persistence
internal/config/resolver.go, internal/config/writer.go, internal/config/*_test.go
Notification resolution defaults to both and unfocused. SetNotify trims, validates, preserves blank defaults, and atomically writes notification settings.
Runtime notifier reconfiguration
internal/notify/notify.go, internal/notify/notify_test.go
Notifier.Configure applies mode and focus changes immediately while synchronizing configuration reads and updates.

CLI notification configuration

Layer / File(s) Summary
CLI notification configuration
internal/cli/command_center.go, internal/cli/config_notify.go, internal/cli/config_notify_test.go
zero config notify supports display, update, reset, validation, and JSON output. Existing summary behavior remains available without a subcommand.
CLI fixture coverage
internal/cli/exec_test.go
The project configuration fixture explicitly sets notification mode to off.

TUI notification configuration

Layer / File(s) Summary
TUI command and state
internal/tui/commands.go, internal/tui/model.go, internal/tui/notify_select.go
The TUI adds /notify, tracks mode and focus mode, validates input, applies changes to the live notifier, persists preferences, and renders notification state.
Notification picker and tests
internal/tui/picker.go, internal/tui/*_test.go
A picker exposes four mode/focus combinations and commits selections through the same path as typed /notify input. Tests cover persistence, validation, live updates, picker behavior, and state rendering.

Addressed all three CodeRabbit findings in 334c688:

  1. config_notify.go — omitted flags wiping stored values: fixed. Omitted --mode/--focus now reuse the current resolved value; --reset is the only path that clears both. Added TestRunConfigNotifyFocusOnlyPreservesMode and strengthened TestRunConfigNotifyWritesModeChange to assert focus preservation.

  2. notify_select.go — trailing /notify arguments silently accepted: fixed. More than two tokens now returns a usage error (TestNotifyCommandRejectsTrailingArguments).

  3. notify_select.go — choice not applied to the live notifier: fixed, and the finding was right that the old message overclaimed. Added notify.Notifier.Configure (mutex-guarded policy swap preserving sinks/focus/writer, TestConfigureAppliesImmediatelyAndKeepsSinks); /notify now calls it, so the change applies on the next permission prompt in the same session (TestNotifyCommandAppliesToLiveNotifier). The "applies on next prompt" line was replaced by the persistence note only.

On the docstring pre-merge warning (51% vs 80%): the new exported surface (SetNotify, Configure, the /notify handler) is documented; the gap is concentrated in small unexported test helpers and arg-parsing internals consistent with the surrounding code's comment density. Happy to add more if maintainers want it.

Full suite: go test ./... -race green (85 packages), go run ./cmd/zero-release build + smoke pass, gofmt/vet clean.

Comment thread internal/notify/notify.go
Configure (334c688) made cfg mutable at runtime, but Notify still read
n.cfg.Mode before acquiring n.mu — a data race with a concurrent
Configure. Move the mode check inside the critical section and copy cfg
to a local for all reads.

Regression test TestConfigureConcurrentWithNotify runs Configure
concurrently with Notify; verified it reports DATA RACE on the unfixed
code and passes after the fix (go test -race -count=5).

Thanks for this, and sorry it sat unreviewed for a while. The feature is worth having and the lock fix in the last commit is right. Three things to fix before it lands, and they are all one mistake, so I have written them as one.

The root of it: the PR treats the resolved config as if it were the user's choice. config.Resolve now fills in notify.mode when the user set nothing, and three separate paths then read that filled-in value back as though a person had picked it.

1. The default reaches headless zero exec, and the change that hides it is in the test fixture.

exec.go:505 builds the notifier with FocusMode: FocusAlways and no TTY or CI check, with a comment saying it always emits when a mode is configured. Before this PR an unconfigured user resolved to an empty mode and the notifier returned before writing; now it writes. On head an ordinary zero exec puts 17 bytes of BEL and OSC-9 on stderr where base wrote nothing, including under -o json and -o stream-json.

The only change this PR makes to that path is adding "notify": {"mode": "off"} to the fixture of TestRunExecUsesProjectConfigAndOpenAICompatibleProvider, which is the repo's existing empty-stderr canary. Put the fixture back the way base has it and the test fails on its own property assertion:

exec_test.go:992: expected empty stderr, got "\a\x1b]9;Zero: ready\a"
--- FAIL: TestRunExecUsesProjectConfigAndOpenAICompatibleProvider

The decisive part is that the resolver default is not needed for the feature at all. effectiveTUINotifyMode at internal/tui/model.go:890 already maps an empty mode to both on the TUI side by itself, so moving the default out of Resolve and leaving it to the TUI makes exec silent again, lets that fixture go back, and keeps the behaviour you actually want. Worth noting too that zero exec emits Completion, while the permission-prompt alert this PR is about is AwaitingInput from model.go:5642 and :5678, so exec was never in scope. A rider on the same cause: with ZERO_NOTIFY_WEBHOOK_URL set, a headless run now POSTs on every completion where base sent none, which also makes webhook_wire.go's "for example --notify both" comment stale.

2. zero config notify writes a value the user did not choose into their global config.

config_notify.go:40 seeds the write from resolved.Notify, which is project-merged and default-filled, and config.SetNotify then replaces the whole block in the user file. So running zero config notify --focus always inside a repo whose .zero/config.json sets mode: off copies that project's off into the user's global config, where it follows them into every other project, even though the only flag they passed was --focus. With no project config at all, --mode off still writes focusMode: unfocused, pinning today's built-in default as an explicit choice, which contradicts SetNotify's own comment that a blank value means use defaults.

The comment above that block only reasons about the omitted-flag case, and it is right that a full replace would be wrong. The missing half is that the preserved value has to come from the user's own file, not from the resolved view. Nothing pins this: none of the new tests pass a ProjectConfigPath, so resolved and user are the same object and the bug cannot show. The same shape is in the TUI's mode-only branch at notify_select.go:73, which reuses m.notifyFocusMode seeded from the resolved value.

3. The picker preselects a row that is not your current setting, and Enter commits it.

picker.go:1073 says the active pair is preselected so Enter keeps it, and that holds for the four canned rows. For the other eight valid pairs the cursor falls to row 0, so opening a bare /notify on (off, always) and pressing Enter writes (both, unfocused). /notify bell, the value the command's own usage string advertises, produces a pair the picker cannot represent, and the "Bell only" row means (bell, always), so the two surfaces disagree on what bell is. TestNotifyPickerOpensOnBareNotify asserts preselection only for an in-list pair, so all eleven notify tests stay green. newThemePicker enumerates its whole domain, which is why the same fallback is harmless there.

The fix, as one change. Move the default out of config.Resolve into the TUI, where effectiveTUINotifyMode already does the job. Seed the zero config notify write, and the TUI's mode-only branch, from the user config file's own notify block so an omitted flag preserves the user's value and a blank field stays blank. Then either enumerate the full mode and focus space in the picker the way the theme picker does, or keep the four curated rows and refuse to commit on Enter when the active pair is not one of them. Three tests would have caught all of this: one that zero exec writes nothing to stderr on a clean run, one that passes a ProjectConfigPath to zero config notify, and one that sends Enter to an open picker from a pair that is not in the list.

Things I checked that are fine, so you do not need to chase them: the concurrency fix is load-bearing and reachable, since Configure runs on the update goroutine and Notify fires from the run goroutine; an explicit opt-out survives resolution in every shape including whitespace and both config layers; the picker opens no new path to a permission decision and does not disturb pending attachments; only Enter and the repeat click commit, and navigation, Esc, resize and paste write nothing; SetNotify validates both fields, preserves unrelated top-level keys and writes through temp-file and rename. The unknown-key loss in writeConfigFile is pre-existing and repo-wide, not something this PR introduces, and action.yml already passes --no-notify, so CI job logs are not the exposed surface. Direct zero exec from a script or cron is.
