hermes 535ef64a0c docs: add idx-core / idx-mcp system design
Accepted design for extracting idx-core as the shared data layer, the
agent-native CLI output contract, idx-mcp tools, packaging, and the
parity gates (golden output tests plus live A/B check) that the
refactor must pass before merging to main.

# AGENTS.md
`idx-cli` is a Rust CLI (binary `idx`) for Indonesian stock market analysis
(`stocks`) and KSEI shareholder ownership (`ownership`).

Docs:
- `docs/ARCHITECTURE.md`: providers, ownership ingest/discovery, error and output contract
- `docs/CONVENTIONS.md`: types, naming, testing, and git rules
- `docs/OWNERSHIP_SYNC.md` / `docs/OWNERSHIP_PUBLISH.md`: snapshot consumer contract / maintainer publishing
- `docs/SMOKE.md`: Nix checks, test layout, and the live drift check
- `docs/DESIGN.md`: idx-core / idx-mcp design and parity gates
- `ROADMAP.md`: open work
## Rules
1. Keep data access provider-driven; no ad hoc fetches in `cli/`.
2. Keep parse/normalize functions pure.
3. Tests use fixtures and `IDX_USE_MOCK_PROVIDER=1`; never hit the live network.
4. Output contract: tables on stdout, one JSON document with `-o json`, errors
on stderr (JSON-shaped in JSON mode), stdout empty on failure.
5. Keep ownership queries (`releases`, `ticker`, `changes`, ...) working across
every ingest path: XLSX, legacy PDF, archive ZIP/TXT, and snapshot sync.
6. `ownership import --fetch-bing` is intentionally unsupported.
7. Output parity is a contract: never edit golden files to make a change pass.
After changing CLI behavior, run the live check and report its summary;
report IDX `403`s explicitly rather than counting them as passes.
## Verify
```bash
nix flake check -L # canonical gate (fmt, clippy, tests, package)
nix develop --command cargo test <name> # focused loop
scripts/live-smoke.sh # opt-in live provider drift check
```
