Add Finam Trade Pro REST plugin with gRPC JWT renewal

[konard]

Summary

Refs #166.

Adds a new finam-trade Teleton plugin with 27 Finam Trade API tools covering accounts, orders, market data, instruments, reports, and usage metrics.

This PR implements the REST request/response tool surface and an opt-in gRPC JWT renewal stream. It does not yet expose Finam's market/account/order/report streaming subscriptions as Teleton tools.

Implementation

• Added FinamAuth for FINAM_SECRET loading, JWT session creation, JWT exp parsing, pre-expiry refresh, token-details account discovery, and optional gRPC AuthService.SubscribeJwtRenewal support.
• Added a REST client with HTTPS/SSRF guardrails, request timeouts, 200 requests/minute limiting, retry handling for transient statuses, and one automatic re-authentication on 401/403.
• Added account, order, market, instrument, and report tool groups with JSON Schema parameters and safe { success, data/error } responses.
• Added SQLite-backed cache table for instruments/exchanges when sdk.db is available.
• Added plugin README, .env.example, manifest metadata, package lock, registry entry, and root README listing.

Review Follow-Up

• Re-checked the current official Finam REST docs for order, SL/TP, and report payload shapes and added tests for the documented payload mappings.
• Fixed the SSRF guard to reject IPv6 loopback, unique-local, link-local, and IPv4-mapped private/local targets.
• Added opt-in gRPC JWT renewal using @grpc/grpc-js and a minimal AuthService.SubscribeJwtRenewal proto.
• Addressed the CodeQL regex review by replacing regex-based gRPC target stripping with index-based authority extraction and regression coverage for fragment-heavy input.
• Added a credential-gated live smoke runner: npm run finam:live-smoke.
• Added README/.env guidance for live smoke evidence, trading safety gates, and known production-readiness limits.

Operational Readiness / Known Limits

• Live positive broker smoke tests were not run in this Codex workspace because FINAM_SECRET, FINAM_LIVE_ACCOUNT_ID, and sandbox/non-production order payloads are not available in the environment.
• The new smoke runner is ready for credentialed validation and covers:
  • finam_get_accounts
  • finam_get_account_info
  • finam_generate_report
  • real JWT session creation and pre-expiry refresh
  • real 401/403 recovery after an intentionally invalid cached JWT
  • negative auth failure with an invalid secret
  • gated finam_place_order and finam_place_sltp checks with explicit JSON payloads
  • optional gRPC JWT renewal startup alongside a REST request when FINAM_LIVE_ENABLE_GRPC=1
• Trading smoke checks are disabled unless FINAM_LIVE_ENABLE_TRADING=1 and explicit FINAM_LIVE_PLACE_ORDER_JSON / FINAM_LIVE_SLTP_JSON payloads are supplied. Returned order IDs are cancelled by default.
• Broader Finam gRPC market/account/order/report streaming tools are intentionally out of scope for this PR.
• This PR should stay as Refs #166 and avoid issue-closing keywords unless the remaining gRPC streaming scope is accepted as follow-up work.

Verification

npm run finam:live-smoke -- --dry-run
node --test plugins/finam-trade/tests/*.test.js
npm run validate
npm run lint
npm test
npm run typecheck
node scripts/build-sdk.mjs
npm audit --audit-level=high --prefix plugins/finam-trade
npm audit --audit-level=high
npx eslint experiments/finam-live-smoke.mjs
git diff --check

Results:

• Live smoke dry run: passed and prints the required/gated checks without requiring plugin dependencies or secrets.
• Focused Finam tests: 16 passed.
• Full test suite: 398 passed.
• npm run validate: passed with the existing casino empty-tools warning.
• npm run lint: passed with existing repo warnings only, no errors.
• npm run typecheck: passed.
• node scripts/build-sdk.mjs: passed.
• npm audit --audit-level=high --prefix plugins/finam-trade: passed with 0 vulnerabilities.
• Root npm audit --audit-level=high: passed; npm still reports existing moderate advisories below the configured threshold.
• Live positive broker smoke tests: blocked on non-production Finam credentials and explicit safe order/SLTP payloads.
• PR status: draft pending redacted positive broker smoke evidence from a non-production Finam account.

Thanks for the implementation — there is a lot of good structure here, and the plugin already looks much closer to something Teleton can build on. However, I don’t think PR #167 is ready to merge yet.

There are still a few important issues to address:

1. The Finam REST order payload shape appears to be incorrect.
   In the current implementation/tests, finam_place_order sends fields like:

   • quantity: { value: "10" }
   • limit_price: { value: "150.50" }

   But the official Finam REST docs for POST /v1/accounts/{account_id}/orders describe these request fields as plain strings, not nested { value: ... } objects:
   https://tradeapi.finam.ru/docs/guides/rest/orders_service/PlaceOrder/

   Since the tests currently assert the nested-object payload, this looks like the plugin may be validating the wrong request shape against its own mocks rather than against the actual API contract. Please re-check all trading/report payload mappings against the live REST docs, especially:

   • finam_place_order
   • finam_place_sltp
   • any endpoint using decimal fields

2. This PR still does not satisfy the issue’s REST + gRPC requirement.
   Issue 📋 Разработка плагина Finam Trade Pro для Teleton #166 explicitly asks for support for both REST and gRPC “where applicable”, and even specifies @grpc/grpc-js in the requested plugin architecture. But this PR explicitly says it uses REST only and keeps grpc_base only for future work.

   That means the implementation may be acceptable as a REST-only MVP, but it should not be treated as fully completing 📋 Разработка плагина Finam Trade Pro для Teleton #166 in its current form. Please either:

   • extend the plugin with actual gRPC support where applicable, or
   • narrow the scope/claim and stop presenting this PR as fully closing the issue.

3. The SSRF guard in assertSafeHttpsUrl is incomplete.
   It blocks localhost and private IPv4 ranges, but does not appear to block IPv6 loopback/private addresses such as:

   • [::1]
   • [fc00::/7]
   • [fd00::/8]

   Since this helper is part of the plugin’s security boundary, IPv6 local/private targets should also be rejected.

Overall, I like the direction and the codebase shape, but I would strongly recommend fixing at least items 1 and 3 before merge, and clarifying or completing item 2 so the PR matches the actual acceptance criteria of #166.

Thanks for the follow-up iteration — this revision is clearly stronger than the previous one.

The earlier concerns about REST decimal payload shape and IPv6/private-network SSRF coverage look materially addressed now:

• the order / SLTP / report request-body mappings are now documented and covered by tests,
• the SSRF guard was extended to reject IPv6 loopback, unique-local, link-local, and IPv4-mapped private/local targets,
• the PR also now includes a real gRPC component instead of only carrying grpc_base as a placeholder.

That said, I still see two points that should be resolved before merge:

1. There is still an unresolved CodeQL / GitHub Advanced Security finding on plugins/finam-trade/src/grpc.js:

   • “Polynomial regular expression used on uncontrolled data”

   Since this is in the new gRPC/security-sensitive surface, I would strongly recommend addressing it explicitly before merge:

   • either fix the regex/path parsing logic so the warning goes away,
   • or document why the finding is a false positive and suppress it with a clear justification.

   Right now this leaves the new gRPC renewal implementation with an open security review concern.

2. The PR scope is now much closer to issue 📋 Разработка плагина Finam Trade Pro для Teleton #166, but it still does not fully implement the broader gRPC surface implied by the issue.
   The PR body explicitly says that only REST request/response tools plus opt-in AuthService.SubscribeJwtRenewal are implemented, while market/account/order/report streaming subscriptions are not exposed as Teleton tools yet.

   That means one of these should happen before merge:

   • either change the PR/issue linkage to reflect that this is a substantial REST-first implementation with partial gRPC support (Refs #166 / partial completion),
   • or complete the remaining gRPC/tooling scope if the intention is to keep Fixes #166.

So from my side:

• the previous implementation blockers around payload compatibility and SSRF look resolved,
• but I would still not call this fully merge-ready until the CodeQL finding is handled,
• and I would avoid closing 📋 Разработка плагина Finam Trade Pro для Teleton #166 with this PR unless you are comfortable treating the remaining gRPC streaming scope as out-of-scope for that issue.

Overall, this is now a much stronger PR, but I would still ask for one more cleanup pass on the security finding and the issue-closure claim.

Follow-up to the latest review:\n\n- Addressed the CodeQL regex concern: current plugins/finam-trade/src/grpc.js uses index-based gRPC authority extraction instead of regex stripping, and commit 197ebf1 adds regression coverage for fragment-heavy input such as repeated # characters.

The static review looks much better now, and the earlier implementation issues appear resolved. At this point, the remaining concern is not the diff itself but merge confidence for a trading/broker integration.

Before merge, I would like one more focused hardening pass aimed at operational safety, with evidence in the PR:

1. Please run and document live smoke tests against a non-production Finam account / sandbox (or the safest available test environment), covering at least:

   • finam_get_accounts
   • finam_get_account_info
   • finam_place_order
   • finam_place_sltp
   • finam_generate_report
   • one negative-path case such as invalid symbol / auth failure / timeout

2. Please confirm the real JWT lifecycle behavior, not only unit-test coverage:

   • initial session creation works,
   • pre-expiry refresh works,
   • 401/403 recovery works,
   • optional gRPC JWT renewal does not interfere with the REST flow.

3. Please add a short “production readiness / known limits” note to the PR description or README that explicitly states:

   • what was tested live,
   • what remains unverified in real broker conditions,
   • and whether broader gRPC streaming is intentionally out of scope for this PR.

4. If hive-mind / Codex generated or updated this implementation, please make sure the final PR comment includes the concrete verification evidence rather than only “all checks passed”, because for a broker plugin green CI alone is not enough to establish merge confidence.

I am not asking for a large redesign here. The code review is already in much better shape. What is still needed is a final evidence-based validation pass so this can be merged with professional confidence rather than only static confidence.

[konard]

Follow-up to the operational-safety review:

• Added commit 4c30fa6 with a credential-gated live smoke runner: npm run finam:live-smoke.
• The runner covers the requested positive paths when credentials are available: finam_get_accounts, finam_get_account_info, finam_generate_report, real JWT session creation/pre-expiry refresh, real 401/403 recovery, negative auth failure, gated finam_place_order, gated finam_place_sltp, and optional gRPC JWT renewal alongside REST.
• Trading checks are intentionally gated by FINAM_LIVE_ENABLE_TRADING=1 plus explicit FINAM_LIVE_PLACE_ORDER_JSON / FINAM_LIVE_SLTP_JSON; returned order IDs are cancelled by default.
• Updated the PR body and README to state the current production-readiness limits and to keep this as Refs #166, not Fixes #166.

What I could verify in this workspace:

npm run finam:live-smoke -- --dry-run
node --test plugins/finam-trade/tests/*.test.js
npm run validate
npm run lint
npm test
npm run typecheck
node scripts/build-sdk.mjs
npm audit --audit-level=high --prefix plugins/finam-trade
npm audit --audit-level=high
npx eslint experiments/finam-live-smoke.mjs
git diff --check

Results: focused Finam tests passed (16), full suite passed (398), validate/lint/typecheck/build-sdk passed, high-severity audits passed, and the dry-run prints the credentialed smoke plan without secrets.

Live positive broker smoke tests were not run here because this environment does not have FINAM_SECRET, FINAM_LIVE_ACCOUNT_ID, or non-production order/SLTP payloads. I am leaving the PR as draft until someone with a safe Finam test account can run the new smoke runner and paste the redacted JSON evidence into the PR.

[konard]

Additional follow-up after the new smoke-runner commit:

• GitHub Advanced Security opened a new CodeQL alert on experiments/finam-live-smoke.mjs for possible clear-text logging of environment-derived data.
• Fixed in b712aca by changing the emitted smoke report to whitelisted evidence only: no API base value, account id, order id, report id, symbol, token, secret, or raw live error text is printed.
• Fresh checks on SHA b712aca643294b1c5b9e06e8d889363bf918fd3b are now all green: CI, Plugin Dependencies, Deploy, CodeQL workflow, and the separate GitHub Advanced Security CodeQL check.

The remaining blocker is still live positive broker validation with a non-production Finam account. The PR remains draft until that credentialed smoke evidence is supplied.

Thanks for the latest pass — this PR is much stronger now.

The earlier code-level concerns around payload mapping, SSRF hardening, and CodeQL findings look materially addressed, and the new npm run finam:live-smoke runner is a good addition.

However, I still would not call this fully merge-ready for a broker/trading integration until these two remaining points are resolved:

1. Live broker validation is still missing.
   The PR now has the right smoke-runner and documents the intended checks, but the latest follow-up explicitly says the positive live smokes were not actually run because FINAM_SECRET, FINAM_LIVE_ACCOUNT_ID, and safe order/SLTP payloads were unavailable.

   For this kind of plugin, that means the remaining risk is no longer static code quality but unverified real broker behavior.

   Before merge, I would still want redacted evidence from a non-production Finam run covering at least:

   • finam_get_accounts
   • finam_get_account_info
   • finam_generate_report
   • JWT session creation / refresh
   • 401/403 recovery
   • and, if this PR is intended to validate trading paths too, gated finam_place_order and finam_place_sltp

2. The PR body is still internally inconsistent about issue closure.
   It says the PR should remain Refs #166 and that broader Finam gRPC streaming is still out of scope, but the body still ends with:

   Fixes xlabtg/teleton-plugins#166

   That should be cleaned up before merge unless the explicit decision is that the remaining gRPC streaming scope is not required for closing 📋 Разработка плагина Finam Trade Pro для Teleton #166.

So from my side:

• code review concerns are mostly resolved,
• but professional merge confidence still requires real non-production smoke evidence,
• and the PR description should be made internally consistent before final approval.

Follow-up to the latest review:

• Cleaned up the PR body so it no longer contains Fixes xlabtg/teleton-plugins#166; it now consistently uses Refs xlabtg/teleton-plugins#166 and keeps the broader gRPC streaming scope as follow-up/out-of-scope for this PR.
• Added an explicit PR-body note that the PR remains draft pending redacted positive broker smoke evidence from a non-production Finam account.
• Re-ran the local smoke dry-run: npm run finam:live-smoke -- --dry-run passed and lists the credentialed checks without requiring or printing secrets.
• Re-checked current GitHub PR checks on SHA b712aca643294b1c5b9e06e8d889363bf918fd3b: Analyze, Build, CodeQL, Lint, Test, TypeScript, deploy, and validate are all passing.

No source-code changes were needed in this pass, so there is no new commit to push. I am intentionally leaving the PR as draft because live positive broker validation still requires FINAM_SECRET, FINAM_LIVE_ACCOUNT_ID, and safe non-production order/SLTP payloads.
