Summary

A successful Read of saved JSON such as {"output":"MemoryError","exit_code":1,"error":null} is mistaken for a failed shell command. Stage and Auto then select the capable tier despite is_error=false.

- retrieval call ID -> infer execution status from the returned text
+ retrieval call ID -> retain whether the paired tool is a shell read
+ inspect execution wrappers only for shell reads

Keep successful built-in read/search/editor-view content out of severity and test-pass signals. Preserve Hermes/Codex shell failure detection, explicit failed-tool flags, the missing-file exemption, recent-window slots and latest-call-ID behavior. This completes the provenance distinction missing from the shell-wrapper handling in #964; #837 established the successful-retrieval contract.

Tracks SWITCH-1870 / NVBug 7067110.

Evidence

• Before: on clean main 6e4864d0, the new content/provenance unit regressions fail (84 existing/control tests pass). A native-server comparison produces two false Stage/Auto escalations and six passing controls; eight real Hub completions and eight independent decision calls all return HTTP200.
• After: the same eight native-server scenarios select the expected targets. Both successful Read variants stay efficient; genuine terminal failures and explicitly failed Read results still select capable. Eight further real Hub completions and eight decision calls return HTTP200. Fresh sessions, fixed Luna/Sol role bindings, low effort, retries0; source/binary identities and owned-process cleanup verified.
• cargo test --locked --release -p switchyard-libsy -p switchyard-runner -p switchyard-llm-client: 708 passed, 0 failed. Includes the existing Hermes/Codex wrapper controls and shared Stage/Advisor consumers.
• cargo fmt --all -- --check and cargo clippy --locked -p switchyard-libsy --all-targets -- -D warnings pass.
• Controlled tool histories with real provider answers; no autonomous tools or agent harness. RC1 remains affected until a delivered candidate includes and verifies this repair.

Merge Danger

Door: two-way

Blast Radius: routing

Tool-signal extraction is shared by Stage/Auto and Advisor guards. Only successful built-in retrieval content loses its false execution-status interpretation. No model, threshold, public API or configuration change.

Summary by CodeRabbit

• Bug Fixes
  • Shell retrieval results now report failures based on shell-specific status details. Non-shell retrieval results are no longer incorrectly marked as failures based on their contents.
  • When a call ID is reused, failure handling reflects the latest call’s type. Explicit retrieval failure flags and missing-file exemptions remain supported.

Walkthrough

Tool-result handling now tracks whether each retrieval call uses a shell tool. It parses shell execution status only for matching shell retrieval results. Tests cover built-in read tools, explicit error flags, and reused call IDs.

Changes

Retrieval Result Handling

Layer / File(s)	Summary
Track retrieval provenance crates/libsy/src/algorithms/util/tool_signals.rs	Retrieval call IDs now store whether the call uses a Bash tool. Reusing an ID updates its recorded provenance.
Gate shell-status parsing crates/libsy/src/algorithms/util/tool_signals.rs	Shell-status parsing applies only to matching shell retrievals. Tests cover built-in read results, explicit error flags, and reused call IDs.

Merge Risk: Minimal · up to 7791a

This change stops successful built-in reads of JSON content from being misread as failed shell runs, while keeping genuine shell-failure detection. No merge-blocking risk was found in the supplied context.

Full details: Title check

Explanation

The title "fix(stage): retain retrieval tool status provenance" matches the main change. The diff records whether each retrieval call is a shell call and limits shell-failure parsing (Hermes/Codex JSON fields and pre-Output exit status) to shell retrievals. The PR objectives state the same intent: keep successful built-in read, search, and editor-view content out of failure signals. The title names the concept (provenance of retrieval status) without listing files. The conventional-commit scope "stage" matches the Stage/Auto routing area the objectives describe.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 1 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

_{A rabbit reads the shell’s report,
And checks which tool made each call.
Read results keep their own contents,
While shell failures still signal.
Reused IDs take their latest mark,
Then off hops the rabbit, pleased.}
