Mission Manifest — Install UX Hardening

Persistent document tracking full mission scope, status, and session history. Updated by the orchestrator at each phase transition and milestone completion.

Mission

ID: install-ux-hardening-20260405 Statement: Close the remaining gaps in the Mosaic Stack first-run and teardown experience uncovered by the post-cli-unification audit. A user MUST be able to cleanly uninstall the stack; the wizard MUST make security-sensitive surfaces visible (hooks, password entry); and CI/headless installs MUST NOT hang on interactive prompts. The longer-term goal is a single cohesive first-run flow that collapses mosaic wizard and mosaic gateway install into one state-bridged experience. Phase: Complete Current Milestone: — Progress: 3 / 3 milestones Status: complete Last Updated: 2026-04-05 (mission complete) Parent Mission: cli-unification-20260404 (complete)

Context

Post-merge audit of cli-unification-20260404 (AC-1, AC-6) validated that the first-run wizard covers first user, password, admin tokens, gateway instance config, skills, and SOUL.md/USER.md init. The audit surfaced six gaps, grouped into three tracks of independent value.

Success Criteria

• AC-1: mosaic uninstall (top-level) cleanly reverses every mutation made by tools/install.sh — framework data, npm CLI, nested stack deps, runtime asset injections in ~/.claude/, npmrc scope mapping, PATH edits. Dry-run supported. --keep-data preserves memory + user files + gateway DB. (PR #429)
• AC-2: curl … | bash -s -- --uninstall works without requiring a functioning CLI. (PR #429)
• AC-3: Password entry in bootstrapFirstUser is masked (no plaintext echo); confirm prompt added. (PR #431)
• AC-4: Wizard has an explicit hooks stage that previews which hooks will be installed, asks for confirmation, and records the user's choice. mosaic config hooks list|enable|disable surface exists. (PR #431 — consent; PR #433 — finalize-stage gating now honors state.hooks.accepted === false end-to-end)
• AC-5: runConfigWizard and bootstrapFirstUser accept a headless path (env vars + --yes) so tools/install.sh --yes + MOSAIC_ASSUME_YES=1 completes end-to-end in CI without TTY. (PR #431)
• AC-6: mosaic wizard and mosaic gateway install are collapsed into a single cohesive entry point with shared state; gateway install is now terminal stages 11 & 12 of runWizard, session-file bridge removed, mosaic gateway install preserved as a thin standalone wrapper. (PR #433)
• AC-7: All milestones shipped as merged PRs with green CI and closed issues. (PRs #429, #431, #433)

Subagent Delegation Plan

Milestone	Recommended Tier	Rationale
IUH-M01	sonnet	Standard feature work — new command surface mirroring existing install
IUH-M02	sonnet	Small surgical fixes across 3-4 files
IUH-M03	opus	Architectural refactor; state machine design decisions

Risks

• Reversal completeness — runtime asset linking creates .mosaic-bak-* backups; uninstall must honor them vs. when to delete. Ambiguity without an install manifest.
• npm global nested deps — npm uninstall -g @mosaicstack/mosaic removes nested @mosaicstack/*, but ownership conflicts with explicitly installed peer packages (@mosaicstack/gateway, @mosaicstack/memory) need test coverage.
• Headless bootstrap — admin password via env var is a credential on disk; needs clear documentation that MOSAIC_ADMIN_PASSWORD is intended for CI-only and should be rotated post-install.

Out of Scope

• mosaicstack.dev/install.sh vanity URL (blocked on marketing site work)
• Uninstall for the @mosaicstack/gateway database contents — delegated to mosaic gateway uninstall semantics already in place
• Signature/checksum verification of install scripts
