hermes b236c7f9d9 fix(ownership): report a Cloudflare challenge as its own error and result
When Cloudflare answers idx.co.id with a challenge, curl fails with only
`curl: (22)`, which exits 4 like any other HTTP failure, and every profile
is tried twice. A challenge needs a browser, so no profile can solve it. The
source is monthly, so the publisher only needs one run per month to get
through: treat a challenge as "retry tomorrow" and alert on stale data.

- Add IdxError::CloudflareChallenge (CLOUDFLARECHALLENGE, exit 6), detected
  from the cf-mitigated header. curl reports it on stderr through --write-out,
  because --fail drops the response.
- A URL with a challenge gets one round of profiles; other failures keep two.
  This also covers `stocks flow --source idx`, which now exits 6 on a challenge.
- -v logs which profile fetched each URL.
- Discovery keeps error types, so a challenge survives an announcement miss.
  A source answering with something unparseable still is not called a challenge.
- `ownership discover --require-data-page` fails when the data page cannot be
  read. Default discover is unchanged: it warns and lists older announcements.
- The publisher and builder use that flag, so a failed data page can no longer
  end in a false "up-to-date". A challenge ends in `RESULT: blocked stage=<stage>`,
  exit 6; every other failure stays `RESULT: FAILED`.
- The systemd example treats exit 6 as success and runs the freshness check, so
  the unit fails on FAILED or on stale data.
- live-smoke reports a challenge as CHALLENGED, a failure and never a pass.

Golden change: completions-bash.golden gains `--require-data-page` in the
discover options, one word on one line. It is the direct result of the new flag;
no other golden file changes.

Live check on 2026-11-05 against release/v0.5.0: 19 passed, 2 failed. Both
failures are real challenges (flow-idx, discover), each exit 6 with empty stdout.
The import, releases and ticker cases did not run, because discover did not pass.

Testing and Smoke Checks

Automated gate

nix flake check -L is the canonical local, pre-push, and CI gate. It runs offline with pinned tools:

Check Covers
fmt, clippy formatting and lints (--all-targets)
test unit/module tests, tests/cli.rs CLI integration tests, tests/golden.rs output parity, and crates/idx-mcp/tests/mcp.rs MCP stdio tests
default, package release build and cargo package verification
packaged-cli the wrapped Nix release binary emits JSON, generates completions, and returns a JSON CACHEMISS error with exit 3 offline
ownership-publisher, publisher-test packaged publisher entry point and its regression scenarios
install-script-sh, install-script-dash, shellcheck installer regressions and shell lint

tests/cli.rs is the behavioral suite: it runs the real idx binary against fixture-backed mock providers (IDX_USE_MOCK_PROVIDER=1) and covers output contracts, cache/offline transitions, provider routing, error codes, ownership imports and queries, and snapshot sync.

tests/golden.rs pins the exact output (exit code, stdout, stderr) of every command listed in tests/golden/cases.toml, in table and JSON. A mismatch means user-visible output changed. Regenerate with UPDATE_GOLDEN=1 cargo test --test golden only when the change is intended, and commit the golden diff with the reason.

crates/idx-mcp/tests/mcp.rs drives idx-mcp over stdio JSON-RPC with the mock provider. crates/idx-mcp/tests/golden/tools.json pins what agents see (tool names, descriptions, input schemas); regenerate it the same way after an intended change.

For a focused loop, run one check or filter Cargo tests:

nix build .#checks.x86_64-linux.publisher-test -L
nix develop --command cargo test full_screener

CI cache keys include platform, dependency/toolchain inputs, and checked source contents. The native macOS installer job runs separately to exercise BSD tools.

Live drift check

Fixtures cannot tell when MSN, Yahoo, or IDX change their responses. scripts/live-smoke.sh runs shipped commands against the real upstreams and validates each JSON output shape. It is opt-in and never part of the gate.

nix develop --command scripts/live-smoke.sh                   # stocks + ownership
nix develop --command scripts/live-smoke.sh --group stocks --symbol BBRI
nix develop --command scripts/live-smoke.sh --bin ./result/bin/idx
nix develop --command scripts/live-smoke.sh --compare ./old/bin/idx  # A/B against an older build
scripts/live-smoke.sh --dry-run
  • stocks: every stocks command for one ticker (broker, bandar, flow and flow --source idx on the new binary only, so an older --compare build that predates them is fine), plus compare BUMI,ADRO,AIMS, whose MSN key ratios contain non-finite values.
  • ownership: discover, then imports the newest supported report into a temp DB and lists releases. IDX sits behind Cloudflare and returns 403 to many datacenter IPs, including GitHub-hosted runners; run it from a network IDX accepts. A case that gets a Cloudflare challenge (CLOUDFLARECHALLENGE) prints CHALLENGED and counts as a failure, never as a pass.

--compare <old-idx> runs every case with both binaries back to back, each with its own config and cache, and fails on a different exit code, any added, missing, or retyped JSON key, or changed values for profile, financials, earnings, and ownership results. Build the old side with, for example, nix build "git+file://$PWD?ref=main" -o old.

Each run isolates config, cache, and data under tmp/live-smoke/<timestamp>/ and keeps per-case .stdout, .stderr, and .validation logs there.

scripts/audit-msn-fundamentals.sh is a heavier sweep of valuation output across the whole IDX MSN symbol map, for provider-health audits.

Agent smoke test

The MCP tests prove the protocol works; they cannot show whether a real coding agent picks the right tools. tests/agents/agent-smoke.sh runs each case in tests/agents/cases.json through Claude Code, Codex, pi, Hermes Agent, and opencode in headless mode against a local idx-mcp build, then checks the tools each agent called (and their key arguments) and, with mock data, key facts in the answer. It is opt-in: it needs agent logins and model credits, and agent behavior varies between runs, so it is never part of the gate.

nix develop .#agents --command tests/agents/agent-smoke.sh            # every agent found
nix develop .#agents --command tests/agents/agent-smoke.sh --agents claude,codex --runs 3
tests/agents/agent-smoke.sh --live --case shareholders --keep          # real data
tests/agents/agent-smoke.sh --npx idx-mcp                              # the published npm package
tests/agents/agent-smoke.sh --npx "$(cd npm/idx-mcp && realpath "$(npm pack --silent)")"  # this checkout's wrapper

--npx <spec> registers npx -y <spec> the way users configure it, so each agent's own npx handling and a cold npm install are part of the test. It runs the release binary, so it implies --live; IDX_BINARY_URL swaps in a local one. Hermes Agent replaces a bare npx with its own generic-Linux Node, which NixOS cannot load; on NixOS use nix develop .#agents-fhs, which runs every agent in an FHS sandbox (and agent-fhs hermes for an interactive session). Hermes logs a server's stderr to $HERMES_HOME/logs/mcp-stderr.log; each run keeps a copy next to its output as <case>.<run>.mcp-stderr.

  • Each agent gets an isolated config that registers only the local server; your own agent settings and MCP servers are not loaded or changed. Logins are copied from the agent's home (Codex auth.json, pi and Hermes auth files) into a temp dir that is deleted afterwards; --keep keeps the run output but still deletes every copied agent config.
  • Tools are auto-approved for the run (Claude dontAsk with mcp__idx__*, Codex default_tools_approval_mode="approve"); Claude and pi also get no built-in tools, Hermes only the idx toolset, and opencode permissions that deny its shell, file, and web tools, so they can only answer through MCP.
  • opencode 1 (opencode-ai) and 2 (@opencode/cli) are both supported; the harness reads opencode --version and writes the matching config. Version 2 runs with --standalone, off the shared background service. A wrapper that pins XDG_* paths (such as a Nix opencode2 wrapper) defeats the isolated config dirs; put the plain binary first on PATH.
  • IDX_AGENT_MODEL_<AGENT> picks a model (for example IDX_AGENT_MODEL_CLAUDE=sonnet). IDX_AGENT_EXEC_PREFIX prefixes every agent command, for hosts that inject API keys through a wrapper.
  • With --live (and --npx), a case's live fields replace its mock ones, for prompts that name data only the fixtures have, such as release dates.
  • The run fails only when an agent fails a case in every run; use --runs to measure pass rates. --keep keeps raw agent output and results.jsonl.
  • nix develop .#agents adds Claude Code, Codex, and opencode from nixpkgs after your PATH, so installed versions win. pi and Hermes Agent must be installed on the host. The nixpkgs opencode (1.2.17) lacks run --pure; use a current opencode 1 or 2.
