# Install UX Hardening — IUH-M01 Session Notes
|
|
|
|
## Session: 2026-04-05 (agent-ad6b6696)
|
|
|
|
### Plan
|
|
|
|
**Manifest schema decision:**
|
|
|
|
- Version 1 JSON at `~/.config/mosaic/.install-manifest.json` (mode 0600)
|
|
- Written by `tools/install.sh` after successful install
|
|
- Fields: version, installedAt, cliVersion, frameworkVersion, mutations{directories, npmGlobalPackages, npmrcLines, shellProfileEdits, runtimeAssetCopies}
|
|
- Uninstall reads it; if missing → heuristic mode (warn user)
|
|
|
|
**File list:**
|
|
|
|
- NEW: `packages/mosaic/src/runtime/install-manifest.ts` — read/write helpers + types
|
|
- NEW: `packages/mosaic/src/runtime/install-manifest.spec.ts` — unit tests
|
|
- NEW: `packages/mosaic/src/commands/uninstall.ts` — command implementation
|
|
- NEW: `packages/mosaic/src/commands/uninstall.spec.ts` — unit tests
|
|
- MOD: `packages/mosaic/src/cli.ts` — register `uninstall` command
|
|
- MOD: `tools/install.sh` — write manifest on success + add `--uninstall` path
|
|
|
|
**Runtime asset list (from mosaic-link-runtime-assets / framework/install.sh):**
|
|
|
|
- `~/.claude/CLAUDE.md` (source: `$MOSAIC_HOME/runtime/claude/CLAUDE.md`)
|
|
- `~/.claude/settings.json` (source: `$MOSAIC_HOME/runtime/claude/settings.json`)
|
|
- `~/.claude/hooks-config.json` (source: `$MOSAIC_HOME/runtime/claude/hooks-config.json`)
|
|
- `~/.claude/context7-integration.md` (source: `$MOSAIC_HOME/runtime/claude/context7-integration.md`)
|
|
- `~/.config/opencode/AGENTS.md` (source: `$MOSAIC_HOME/runtime/opencode/AGENTS.md`)
|
|
- `~/.codex/instructions.md` (source: `$MOSAIC_HOME/runtime/codex/instructions.md`)
|
|
|
|
**Reversal logic:**
|
|
|
|
1. If `.mosaic-bak-<stamp>` exists for a file → restore it
|
|
2. Else if managed copy exists → remove it
|
|
3. Never touch files not in the known list
|
|
|
|
**npmrc reversal:**
|
|
|
|
- Only remove line `@mosaicstack:registry=https://git.mosaicstack.dev/api/packages/mosaicstack/npm/`
|
|
- If manifest has the line, use that as authoritative; else check heuristically
|
|
|
|
**PATH reversal:**
|
|
|
|
- Check install.sh: it does NOT add PATH entries to shell profiles (framework/install.sh migration removes old `$MOSAIC_HOME/bin` PATH entries in v0/v1→v2 migration, but new install does NOT add PATH)
|
|
- ASSUMPTION: No PATH edits in current install (v0.0.24+). Shell profiles not modified by current install.
|
|
- The `$PREFIX/bin` is mentioned in a warning but NOT added to shell profiles by install.sh.
|
|
- shellProfileEdits array will be empty for new installs; heuristic mode also skips it.
|
|
|
|
**Test strategy:**
|
|
|
|
- Unit test manifest read/write with temp dir mocking
|
|
- Unit test command registration
|
|
- Unit test dry-run flag (no actual fs mutations)
|
|
- Unit test --keep-data skips protected paths
|
|
- Unit test heuristic mode warning
|
|
|
|
**Implementation order:**
|
|
|
|
1. install-manifest.ts helpers
|
|
2. install-manifest.spec.ts tests
|
|
3. uninstall.ts command
|
|
4. uninstall.spec.ts tests
|
|
5. cli.ts registration
|
|
6. tools/install.sh manifest writing + --uninstall path
|
|
|
|
ASSUMPTION: No PATH modifications in current install.sh (v0.0.24). Framework v0/v1→v2 migration cleaned old PATH entries but current install does not add new ones.
|
|
ASSUMPTION: `--uninstall` in install.sh handles framework + cli + npmrc only; gateway teardown deferred to `mosaic gateway uninstall`.
|
|
ASSUMPTION: Pi settings.json edits (skills paths) added by framework/install.sh are NOT reversed in this iteration — too risky to touch user Pi config without manifest evidence. Noted as follow-up.
