Summary

PR #78 merged while its latest review feedback was still being addressed. This follow-up preserves the fixes completed after the merge:

  • harden n8n schedule, code, split-out, and HTTP import translation
  • accept hyphenated node bindings while leaving compound jq expressions to runtime evaluation
  • split every affected Rust source/test file to stay within the 500-line limit
  • move the affected large inline test modules into _tests.rs files

Validation

  • cargo fmt --all -- --check
  • cargo clippy --workspace --all-targets --all-features -- -D warnings
  • cargo build --workspace --all-targets --all-features
  • cargo test --workspace --all-features
  • no Rust file under crates/ exceeds 500 physical lines

Follow-up to #78.

Summary by CodeRabbit

  • New Features

    • Added approval gates for approving or rejecting paused workflow steps.
    • Added recovery and retry support for interrupted or failed workflow runs.
    • Added stronger recipe validation for inputs, dependencies, references, and workflow calls.
    • Improved tenant-scoped ledger storage, episode tracking, transcripts, scoring, and workflow variants.
  • Bug Fixes

    • Improved n8n imports for HTTP, schedule, switch, and code nodes.
    • Improved binding parsing for indexed paths, hyphenated node identifiers, and trailing content.
    • Improved workflow routing, loop input handling, cancellation, and retry recovery behavior.

When the n8n importer encounters HTTP request configuration it cannot translate, such as JSON body text or body parameters in an unsupported shape, it now inserts a placeholder node instead of silently dropping the configuration. This prevents data loss and makes the incomplete import visible to the user, who must rebuild the request before enabling the flow.

…alls

Consolidate multi-line function calls in the HTTP request mapper into single-line expressions for improved readability. Adjust test assertions to use consistent formatting with the rest of the codebase.

Auto-committed-on: dragonfly
…bindings

The identifier parser now accepts hyphens, which are valid in jq field names. The binding parser also rejects bindings where the field path is followed by non-whitespace content, ensuring that only complete simple bindings are treated as static node references while leaving compound jq expressions to runtime evaluation.

Auto-committed-on: dragonfly
Move the large inline test module from judge.rs into its own file to reduce the module's length and improve readability. The tests are unchanged in behaviour.

Auto-committed-on: dragonfly
The test module was extracted from contracts.rs into its own file, contracts_tests.rs, to reduce the size of the main source file and improve readability. The module declaration now uses the `#[path]` attribute to reference the external test file.

Auto-committed-on: dragonfly
The test module was extracted from driver.rs into a dedicated driver_tests.rs file to reduce the size of the main source file and improve maintainability. The module is now included via a path attribute, preserving all existing test behaviour.

Auto-committed-on: dragonfly
The module-level test block in `host.rs` was extracted into its own file `host_tests.rs` to reduce the size of the main source file and keep test code separate from production logic. The change replaces the inline `mod tests` block with a `#[path = "host_tests.rs"] mod tests;` declaration, leaving only the import and the `host_of` function in the original file.

Auto-committed-on: dragonfly
The test module was extracted from `mod.rs` into its own `mod_tests.rs` file to keep the implementation source clean and reduce the size of the main module. The tests themselves are unchanged.

Auto-committed-on: dragonfly
The inline test module for the MongoDB ledger conformance suite has been extracted into a dedicated `mongo_tests.rs` file, keeping the main module free of test code while preserving the same test logic and its `#[ignore]` attribute.

Auto-committed-on: dragonfly
The inline test module in sqlite.rs was extracted into its own file to reduce the size of the main implementation file and improve maintainability. The module is now loaded via a path attribute pointing to the new sqlite_tests.rs file.

Auto-committed-on: dragonfly
Move the inline `signature_tests` module from `mod.rs` into its own file to reduce the size of the main ledger module and improve test organization. The test logic is unchanged, only relocated via a `#[path]` attribute.

Auto-committed-on: dragonfly
The monolithic service example has been extracted into a separate runtime module, leaving only a single include directive in the original file. This makes the example easier to navigate and maintain by separating the runtime logic from the example entry point.

Auto-committed-on: dragonfly
Move the recipe lowering functions — pasted_values, ask_expression, kind_of, output_of, child_answer, jq_field, jq_quote, parse_steps, call, forward, parse_declared, graph_name, and sanitize_id — into a dedicated lowering module to reduce the size of recipe.rs and keep the intake surface focused on top-level orchestration.

Auto-committed-on: dragonfly
The entire `Ledger` trait implementation for `MongoLedger` has been moved from `mongo.rs` into a new `mongo/ledger_impl.rs` module, replacing the inline code with a single `include!` directive. This reduces the main file by over 300 lines and improves maintainability by isolating the implementation details.

Auto-committed-on: dragonfly
Moves the full `Ledger` trait implementation for `SqliteLedger` out of the main `sqlite.rs` module and into a dedicated `ledger_impl.rs` file, included via `include!`. This reduces the module file by over 300 lines, keeping the public interface and helper functions in the parent while isolating the trait implementation for easier maintenance and testing.

Auto-committed-on: dragonfly
Moved the `Continuation` enum, its `command` method, the `resume_with_checkpointer_inner` function, the `FailureBoundary` struct, and all public retry/resume functions from `resumable.rs` into a new `resumable/continuation.rs` module, replacing the removed code with a single `include!` directive. This reduces the main file by over 300 lines and isolates the continuation logic for easier maintenance and testing.

Auto-committed-on: dragonfly
Moved the private helper functions for trace projection, argument parsing, mock building, breakpoint specification, and debug command construction from the main registry module into a dedicated helpers submodule. This reduces the registry file by over 250 lines and keeps the core registry logic focused on the TestkitRegistry implementation.

Auto-committed-on: dragonfly
…ed module

Move the transcript and paging conformance tests from the monolithic conformance.rs file into a separate transcripts.rs module, reducing the main file by over 170 lines and improving maintainability by grouping related test helpers together.

Auto-committed-on: dragonfly
….rs,crates/tinyflows-adaptive/s

Auto-committed-on: dragonfly
…module

Move the five lineage conformance test functions from the main conformance file into a new submodule, replacing them with an include directive. This keeps the lineage tests together and reduces the size of the conformance module, making it easier to navigate and maintain.

Auto-committed-on: dragonfly
Moved the tenant isolation conformance tests from the main conformance module into a dedicated submodule file to reduce the size of the monolithic conformance file and improve organization of test cases by concern.

Auto-committed-on: dragonfly
Move the five integration tests from the monolithic `driver.rs` into a dedicated `driver_part_02_tests.rs` module, keeping only the `include!` directive in the original file. This reduces the main test file by 280 lines and improves maintainability by grouping related test scenarios in their own module.

Auto-committed-on: dragonfly
Moved the bulk of the integration tests from `driver.rs` into a new `driver_part_01_tests.rs` file, leaving only the `include!` directives that pull in the two part files. This keeps the driver module as a thin dispatcher and makes each test file shorter and easier to navigate.

Auto-committed-on: dragonfly
…/tinyflows-adaptive/tests/intak

Auto-committed-on: dragonfly
Moved the bulk of the intake test file into a new submodule file, leaving only the include directives that pull in the split test files. This keeps the test suite organised without changing any test behaviour.

Auto-committed-on: dragonfly
Moved the child run state fixture and the six tests that depend on it into a dedicated file to keep the main recipe test file focused on the core lowering logic. The extracted tests cover agent prose reading, script stdout access, errand lowering and validation, goal preservation, and control character handling.

Auto-committed-on: dragonfly
Move the use-step lowering tests from the monolithic recipe_tests file into a new recipe_part_01_tests module, keeping the file focused on the remaining test groups. The extracted tests cover callable resolution, input validation, and child-workflow projection, which form a natural unit for independent maintenance.

Auto-committed-on: dragonfly
Move the composed workflow helper and three integration tests from the monolithic `closing.rs` into a dedicated `closing_part_01_tests.rs` file, included via a single `include!` directive. This reduces the main test file by 236 lines and groups related tests together without changing any test logic or behaviour.

Auto-committed-on: dragonfly
Moves two long integration tests from the monolithic interception_e2e.rs file into a dedicated submodule, keeping the main test file focused on the core interception scenarios. The extracted tests cover frame binding resolution and retry error reporting, which are self-contained and benefit from being grouped together.

- Around line 201-207: Update the scope filter used by save_episode, episode,
and episodes() in ledger_impl.rs: for global handles where self.scope.is_none(),
match scope_key with $in containing an empty string and null; for tenant
handles, continue matching the exact scope. Add a MongoDB regression test
covering reading, listing, and updating a legacy global document with a string
_id and no scope_key, ensuring saving updates it rather than creating a
duplicate.

In `@crates/tinyflows-catalog/src/import/n8n/node_mapping/javascript.rs`:
- Line 84: The function-body detection in the JavaScript mapping logic must
recognize valid function expressions even when they occur inside call-argument
parentheses. Update the condition around function-depth tracking so paren_depth
does not exclude a function body, and add a regression case covering a function
callback such as input.map(function (value) { return value; }) to ensure the
nested return is preserved.
- Line 127: Update the JavaScript literal-detection logic around the punctuation
check to recognize regex literals following keyword contexts that can begin an
expression, including return, so embedded values are not scanned as code. Add a
regression test covering a return statement followed by a regex literal and
preserve existing punctuation-based detection.

In `@crates/tinyflows/src/bindings.rs`:
- Around line 122-130: Update parse_node_binding so an indexed path immediately
after .json, such as json[0], is treated as envelope traversal and sets
through_envelope accordingly, while preserving the index and remaining field
path. Add a regression test covering =nodes.fetch.item.json[0].title and
verifying access to the array-valued Item.json succeeds.

Replace ambiguous local references with fully qualified paths in two test files to avoid compilation errors when the local scope does not contain the expected types. This ensures the tests compile correctly regardless of the surrounding imports.

Auto-committed-on: dragonfly
Changed the page parameter in the legacy episode test from `Page::default()` to `Page::first(10)` to ensure the test correctly lists episodes with an explicit page size, preventing potential test failures when the default page size changes.

Auto-committed-on: dragonfly
When scanning JavaScript source for n8n code globals, the parser now records the current parenthesis depth at the point of a `function` keyword. This depth is later compared against the depth when a `{` is encountered, ensuring that only the opening brace belonging to the function declaration itself is treated as its body, rather than any brace at the same nesting level inside a parenthesised expression.

Auto-committed-on: dragonfly
Moves the two indexed binding test cases from `gates_tests.rs` into a separate test file and includes it via `include!`, reducing duplication and making the test suite easier to maintain.

Auto-committed-on: dragonfly
The include path for the indexed binding tests module was pointing to a subdirectory that no longer exists, causing test compilation failures. Updated the path to reference the file directly in the gates directory.

senamakel dismissed coderabbitai[bot]’s stale review August 30, 2026 16:42

All four CodeRabbit findings were fixed in the latest pushed commits, each regression was added, and every associated thread was answered and resolved. A re-review was requested but CodeRabbit reported review rate limiting, so this stale verdict is being cleared after the fixes and full local validation.

Renamed four test files by appending `_tests` to their names, matching the standard Rust test module naming pattern. This change ensures consistency with the project's test organization conventions and avoids confusion between test modules and their containing files.

Auto-committed-on: dragonfly
…ethod shorthand

Extend the n8n code node mapping to also detect when a Python code node uses n8n-specific globals like `$json` or `$input`, not just JavaScript nodes. Refactor the detection logic into a shared `config_uses_n8n_runtime` function that checks both the source code and the language setting, skipping the top-level `return` check for Python since that language does not use the n8n return convention. Additionally, improve the JavaScript lexer to recognise method shorthand syntax (e.g. `myMethod() { ... }`) as a function body boundary, and correctly track `items` bindings that are scoped to arrow function parameters without a block body, preventing false positives when `items` is used as a parameter name.

Auto-committed-on: dragonfly
…lobal items

Add two new test cases to the incompatible n8n code placeholder test: one for a Python helper that returns a value and prints it, and one for JavaScript code that uses items both locally and globally. These cases verify that such patterns are correctly classified as Code and Transform nodes respectively.

Auto-committed-on: dragonfly
Removed an unnecessary line break in the condition that checks for n8n runtime usage, consolidating the if-statement onto a single line for consistent formatting.

Auto-committed-on: dragonfly
Consolidated the condition for detecting function bodies by merging two separate checks into a single combined condition. This removes the redundant `pending_variable_declaration = false` assignment and makes the logic clearer without changing behaviour.

P2 Badge End arrow-parameter bindings at the arrow expression

Fresh evidence in the revised scoped-binding stack is a semicolon-free expression arrow such as const f = items => items.length console.log(items.length); process.stdin.pipe(process.stdout);: the parameter binding is retained until the later semicolon, so the genuinely unbound second items is treated as local. The node is consequently imported as executable Code and fails because TinyFlows supplies no global items; expire expression-bodied arrow parameters at the end of their expression/ASI boundary rather than the next semicolon.

P2 Badge Index the new scoped episode lookup

For newly written Mongo episodes, _id is now a document while the requested string is stored in id, so this query matches via the id branch rather than MongoDB's built-in _id index. ensure_indexes creates no index for episodes, making each episode() lookup scan the collection as recovery history grows; add a compound index covering the scoped id lookup or query the compound _id directly while retaining a legacy fallback.
