chore: add *.tsbuildinfo to .gitignore, remove duplicate dist/ entry

fix: resolve lint errors — remove useless constructor, fix import ordering, replace as any with as unknown as JSONSchema in tests, apply biome formatting
fix: add tsconfig paths for workspace package resolution

+      On first run (no previous steps):
+      1. Read the issue and all comments from Gitea using `tea issues <number>`
+      2. Read project conventions (CLAUDE.md, CONTRIBUTING.md, .cursor/rules/) to understand coding standards
+      3. Assess whether the issue has enough information to produce a test spec
+      4. If insufficient info: comment on the issue via `echo "..." | tea comment <number>` (skip if you already commented), then output status=insufficient_info and terminate
+      5. If sufficient: produce a detailed TDD test spec in markdown covering all scenarios
+
+      On subsequent runs (bounced back by tester with fix_spec):
+      1. Read the tester's output from the previous step to understand what's wrong with the spec
+      2. Revise the test spec accordingly
+
+      After producing the test spec:
+      1. Store it via `uwf cas put-text "<markdown content>"` and capture the returned hash
+      2. Put the hash in frontmatter.plan (required when status=ready)

+      IMPORTANT: Always work in a git worktree, NEVER modify the main working directory directly.
+
+      Set up variables from the current working directory:
+      ```
+      REPO_ROOT=$(git rev-parse --show-toplevel)
+      WORKTREE_BASE=$(dirname $REPO_ROOT)/$(basename $REPO_ROOT)-worktrees
+      ```
+
+      Before starting any work, set up an isolated worktree:
+      1. `cd $REPO_ROOT && git fetch origin` to get latest refs
+      2. First time (no existing branch):
+         - `git worktree add $WORKTREE_BASE/fix/<issue-number>-<short-slug> -b fix/<issue-number>-<short-slug> origin/main`
+         - `cd $WORKTREE_BASE/fix/<issue-number>-<short-slug> && bun install`
+      3. If bounced back from reviewer or tester (branch already exists):
+         - `cd $WORKTREE_BASE/fix/<issue-number>-<short-slug>`
+         - `git fetch origin && git rebase origin/main`
+      4. ALL subsequent work must happen inside the worktree directory.
+
+      Then implement TDD:
+      5. Read the test spec from CAS: `uwf cas get <plan hash>` (find the hash from the latest planner step's frontmatter.plan)
+      6. If bounced back from reviewer or tester: read the previous role's output to understand what needs fixing
+      7. Write tests first based on the spec
+      8. Implement the code to make tests pass
+      9. Ensure `bun run build` passes with no errors
+      10. Run `bun test` to verify all tests pass
+    output: "List all files changed and provide a summary. Frontmatter must include: status (done or failed)."

+      2. If the branch doesn't correspond to the issue, flag it in your output and reject

+      2. Commit with a descriptive message referencing the issue: `git commit -m "type: description\n\nFixes #N"`
+      3. Push the branch: `git push -u origin <branch-name>`
+         - If push hook fails: capture the error log in your output, mark hook_failed

+# CLAUDE.md — json-cas
+
+Self-describing content-addressable storage with JSON Schema typed nodes.
+
+## Project Structure
+
+Monorepo with 4 packages under `packages/`:
+
+| Package | Description |
+|---------|-------------|
+| `json-cas` | Core CAS engine — hashing, schema, store, verify, bootstrap |
+| `json-cas-fs` | Filesystem-backed CAS store |
+| `json-cas-workflow` | Workflow integration layer (schemas + types) |
+| `cli-json-cas` | CLI tool |
+
+## Tech Stack
+
+- **Runtime:** Bun
+- **Language:** TypeScript (strict mode, `exactOptionalPropertyTypes`, `noUncheckedIndexedAccess`)
+- **Build:** `tsc --build` (composite project references)
+- **Test:** `bun test`
+- **Lint/Format:** Biome (`biome check .` / `biome format --write .`)
+- **Publish:** Changesets → npmjs (`@uncaged/*`)
+
+## Commands
+
+```bash
+bun test          # Run all tests
+bun run build     # Build all packages
+bun run check     # Biome lint
+bun run format    # Biome format (auto-fix)
+```
+
+## Code Conventions
+
+### TypeScript
+
+- **Strict mode** — no `any`, no unchecked index access, no implicit overrides
+- **`verbatimModuleSyntax`** — use `import type` for type-only imports
+- **Import paths** — use `.js` extension in imports (ESM convention with bundler resolution)
+- **Export style** — named exports only, re-export from `index.ts`
+
+### Biome Rules
+
+- `noConsole: "error"` globally (except `cli-json-cas`)
+- Recommended ruleset enabled
+- Auto-organize imports via `assist.actions.source.organizeImports`
+- Indent: 2 spaces
+
+### Naming
+
+- Types: `PascalCase` (`CasNode`, `Hash`, `Store`)
+- Functions: `camelCase` (`computeHash`, `createMemoryStore`)
+- Constants: `UPPER_SNAKE_CASE` (`BOOTSTRAP_STORE`)
+- Files: `kebab-case.ts`
+- Test files: co-located as `*.test.ts`
+
+### Key Types
+
+- `Hash` — 13-character uppercase Crockford Base32 string (XXH64)
+- `CasNode` — content-addressed node with schema
+- `Store` — abstract storage interface (get/put)
+
+## Git
+
+- Commit format: `type: description` (conventional commits)
+- Reference issues: `Fixes #N` / `Closes #N`
+- Author: `小橘 <xiaoju@shazhou.work>`
+
+## Before Submitting
+
+1. `bun test` — all tests pass
+2. `bun run check` — no lint errors
+3. `bun run build` — builds cleanly

xiaomo	b062fcbc44	fix: add tsconfig paths for workspace package resolution bun workspace:^ deps don't create node_modules symlinks, so tsc can't resolve @uncaged/* packages by name. Add explicit paths mapping to fix tsc --build.	2026-05-25 04:08:14 +00:00

xiaoju	054d78296a	feat!: self-validating meta-schema for putSchema Replace bootstrap payload with a JSON Schema meta-schema describing our supported schema subset. putSchema now validates input schemas against the meta-schema before storing, rejecting invalid schemas with SchemaValidationError. - bootstrap.ts: self-describing meta-schema (type, properties, required, additionalProperties, anyOf, items, format, title, enum, const, description) - schema.ts: recursive isValidSchema(), SchemaValidationError class - index.ts: export SchemaValidationError - package.json: bump 0.4.0 → 1.0.0 (breaking change) BREAKING CHANGE: meta-schema hash changed, old CAS data invalid.
