Add CLI runtime provider coverage **Started**: 2026-05-31 12:30 **Completed**: 2026-05-31 12:33 **Duration**: 3 minutes **Notes**: * Added runtime coverage for explicit Claude, invalid provider failure before writes, Codex deferred no-mutation behavior, `all` provider routing, install alias Codex routing, provider-aware uninstall, and provider-filtered status/doctor output. * Verified with `npx vitest run apps/cli/tests/cliRuntime.test.js`. **Files Changed**: * `apps/cli/tests/cliRuntime.test.js` - added provider-aware runtime tests. **BQC Fixes**: * Duplicate action prevention: `all` routing test asserts Claude managed hooks are not duplicated. * Trust boundary enforcement: invalid provider test asserts no local settings or hook files are written. *** ### Task T014 - Preserve hook installer regression assertions **Started**: 2026-05-31 12:33 **Completed**: 2026-05-31 12:33 **Duration**: 1 minute **Notes**: * Added a regression assertion that Claude installer runs do not create Codex hook state. * Existing backup, merge, malformed settings, reinstall, backup restore, surgical uninstall, and malformed uninstall assertions remain intact. * Verified with `npx vitest run apps/hooks/tests/installScripts.test.js`. **Files Changed**: * `apps/hooks/tests/installScripts.test.js` - added Claude-installer no-Codex-mutation coverage. **BQC Fixes**: * Trust boundary enforcement: Claude installer tests now explicitly guard the Codex file boundary. *** ### Task T015 - Update hooks README Codex handoff **Started**: 2026-05-31 12:33 **Completed**: 2026-05-31 12:33 **Duration**: 1 minute **Notes**: * Clarified that Phase 10 Session 01 adds CLI routing only and Session 02 owns user-level Codex hook writes, backup, restore, merge, and managed-count diagnostics. * Updated install wording to show default and explicit Claude routes without claiming Codex installation support. **Files Changed**: * `apps/hooks/README_hooks.md` - documented the Session 02 Codex installer handoff and no current user-level Codex writes. **BQC Fixes**: * Contract alignment: hooks documentation now matches the CLI deferred Codex boundary. *** ### Task T016 - Update CLI README provider docs **Started**: 2026-05-31 12:33 **Completed**: 2026-05-31 12:33 **Duration**: 1 minute **Notes**: * Documented `--cli claude|codex|all`, backward-compatible default Claude behavior, deferred Codex mutation, provider-aware diagnostics, and provider-aware uninstall. * Added no-overclaim wording for Codex hook files, auth, provider, telemetry, model, profile, trust state, and custom slash commands. **Files Changed**: * `apps/cli/README_cli.md` - updated provider selection, diagnostics, removal, and current integration boundary docs. **BQC Fixes**: * Contract alignment: command documentation matches current CLI behavior and deferred Codex scope. *** ### Task T005 - Create compact provider posture helper **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Added Claude and Codex provider posture inspection with compact status labels, managed-hook counts, settings state, and backup state. * Kept hook command strings internal to counting only; output formatting never includes raw command bodies. **Files Changed**: * `apps/cli/src/lib/providerPosture.js` - added compact provider posture inspection and formatting. **BQC Fixes**: * Error information boundaries: provider posture exposes labels and counts only. *** ### Task T006 - Extract Claude install behavior **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Moved Claude install and uninstall behavior into `apps/cli/src/installers/claude.js`. * Preserved backup-first Claude writes, malformed settings fallback, managed hook replacement, env preservation, and atomic writes. * Added a settings snapshot restore path if Claude setup fails after local FactionOS settings are written. **Files Changed**: * `apps/cli/src/installers/claude.js` - added Claude provider installer, uninstaller, hook-map merge, and managed-hook detection helpers. **BQC Fixes**: * Resource cleanup: failed writes remove temp files through existing atomic write helpers. * Failure path completeness: partial local settings writes are compensated if later Claude setup fails. *** ### Task T008 - Wire init/install provider dispatch **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Replaced inline init logic with provider dispatch for Claude, Codex, and all providers. * Added an in-flight provider setup lock and validates provider/faction input before mutation paths. * Preserved default Claude behavior and existing success banner for Claude installs. **Files Changed**: * `apps/cli/src/commands/init.js` - added provider plan execution, lock, Claude success output, and Codex deferred output. **BQC Fixes**: * Duplicate action prevention: init/install now use a local provider setup lock. * Trust boundary enforcement: provider selection and faction values are validated before writes. *** ### Task T009 - Update top-level CLI help and dispatch **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Updated help text for `--cli claude|codex|all`, install alias examples, provider-aware status/doctor, and uninstall provider selection. * Dispatch remains through existing command handlers, which now own provider validation. **Files Changed**: * `apps/cli/src/index.js` - updated provider-aware help and examples. **BQC Fixes**: * Contract alignment: help text matches the provider-aware command surface. *** ### Task T010 - Update uninstall provider routing **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Replaced process-spawn uninstall delegation with provider-routed Claude and deferred Codex uninstall boundaries. * Preserved Claude backup restore and surgical managed-hook removal without deleting broader `.factionos` state. * Added an in-flight provider uninstall lock. **Files Changed**: * `apps/cli/src/commands/uninstall.js` - added provider routing, lock, and compact result output. * `apps/cli/src/installers/claude.js` - added Claude uninstall implementation. **BQC Fixes**: * Duplicate action prevention: uninstall now uses a local provider uninstall lock. * Failure path completeness: malformed and absent settings return explicit no-mutation states. *** ### Task T011 - Update status provider filters **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Added `--cli` parsing to status with default all-provider posture. * Status now prints Claude loaded/absent/malformed states and Codex deferred posture without raw hook command bodies. **Files Changed**: * `apps/cli/src/commands/status.js` - added provider selection and compact provider posture output. * `apps/cli/src/lib/providerPosture.js` - provides posture data for status. **BQC Fixes**: * Error information boundaries: status provider output is limited to labels and counts. *** ### Task T012 - Update doctor provider filters **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:30 **Duration**: 6 minutes **Notes**: * Added `--cli` parsing to doctor and moved Claude hook checks behind provider posture inspection. * Codex doctor posture is explicit deferred information and does not inspect Codex settings, auth, provider, telemetry, model, profile, or hook files. **Files Changed**: * `apps/cli/src/commands/doctor.js` - added provider-aware checks and Codex deferred diagnostics. * `apps/cli/src/lib/providerPosture.js` - provides posture data for doctor. **BQC Fixes**: * Error information boundaries: doctor provider output avoids raw settings, env values, local paths, and hook commands. * Trust boundary enforcement: provider selection is validated before diagnostic recovery can mutate stale local diagnostic files. *** ### Task T003 - Create provider parser test scaffold **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:29 **Duration**: 5 minutes **Notes**: * Added focused provider tests for default Claude behavior, explicit Claude, Codex, all-provider expansion, aliases, invalid provider input, and Codex no-mutation behavior. * Verified the scaffold with `npx vitest run apps/cli/tests/cliProvider.test.js`. **Files Changed**: * `apps/cli/tests/cliProvider.test.js` - added provider parser and deferred Codex boundary coverage. **BQC Fixes**: * Trust boundary enforcement: invalid `--cli` values are tested before provider mutation paths run. *** ### Task T004 - Create provider selection helper **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:29 **Duration**: 5 minutes **Notes**: * Added shared provider parsing with Claude defaulting, alias normalization, `all` expansion, compact invalid-provider errors, and provider labels. * Kept parsing isolated so command handlers can reject invalid input before writes. **Files Changed**: * `apps/cli/src/lib/cliProvider.js` - added provider parsing and error helpers. **BQC Fixes**: * Trust boundary enforcement: CLI provider input is normalized and validated through one helper. * Failure path completeness: missing and invalid provider values throw explicit compact errors. *** ### Task T007 - Create deferred Codex installer and uninstaller boundary **Started**: 2026-05-31 12:24 **Completed**: 2026-05-31 12:29 **Duration**: 5 minutes **Notes**: * Added Codex install, uninstall, and posture functions that return deterministic deferred results. * Verified deferred Codex paths do not create `~/.factionos`, write backups, or mutate existing `.codex/hooks.json`. **Files Changed**: * `apps/cli/src/installers/codex.js` - added no-mutation Codex provider boundary. * `apps/cli/tests/cliProvider.test.js` - added no-mutation assertion coverage. **BQC Fixes**: * Trust boundary enforcement: Codex auth, provider, telemetry, model, profile, and hook files are not inspected or changed. * Contract alignment: deferred Codex result shape matches provider installer routing. *** ### Task T002 - Review hooks installer regression and Codex map boundaries **Started**: 2026-05-31 12:23 **Completed**: 2026-05-31 12:24 **Duration**: 1 minute **Notes**: * Reviewed hook installer tests covering backup creation, malformed settings fallback, reinstall idempotency, backup restore, surgical uninstall, and malformed uninstall no-op behavior. * Reviewed hooks README Codex wording confirming current scope is source-map readiness, not user-level Codex hook writes or trust bypass. **Files Changed**: * `.spec_system/specs/phase10-session01-cli-provider-selection-and-installer-split/tasks.md` - marked T002 complete. * `.spec_system/specs/phase10-session01-cli-provider-selection-and-installer-split/implementation-notes.md` - logged hooks source verification. **BQC Fixes**: * None. *** ### Task T001 - Verify Phase 10 CLI prerequisites and touch points **Started**: 2026-05-31 12:22 **Completed**: 2026-05-31 12:23 **Duration**: 1 minute **Notes**: * Confirmed Phase 10 prerequisites are recorded complete in the session spec. * Reviewed current CLI command dispatch, help text, inline Claude init behavior, status/doctor diagnostics, and README command contract before changing routing. **Files Changed**: * `.spec_system/specs/phase10-session01-cli-provider-selection-and-installer-split/tasks.md` - marked T001 complete. * `.spec_system/specs/phase10-session01-cli-provider-selection-and-installer-split/implementation-notes.md` - logged source verification. **BQC Fixes**: * None. *** ## Task Log ### 2026-05-31 -
