Mutes per-request unresolved-variable warnings by default, counts skips, and prints one end-of-scan summary. Use -log-unresolved to restore per-request details.

Closes #3386

Summary by CodeRabbit

• New Features
  • Added the -log-unresolved (-lu) option to show warnings for each request skipped because template variables could not be resolved.
  • Scans now report the total number of skipped requests, with a hint for enabling per-request warnings when applicable.
  • Requests with unresolved variables are skipped without being reported as failed requests.

Unresolved Variable Handling

Layer / File(s)	Summary
Progress and logging configuration pkg/types/types.go, pkg/progress/*, cmd/nuclei/main.go, internal/tests/testutils/testutils.go	Adds the LogUnresolved option and progress counter APIs, initializes and tests the counter, and updates the mock progress client.
Centralized unresolved-variable helper pkg/protocols/common/unresolvedvars/*	Adds unresolved-variable detection, skip counting, optional warning logging, and unit tests.
Protocol integration and scan reporting pkg/protocols/{dns,http,network}/request.go, internal/runner/runner.go	Routes unresolved-variable cases through the helper and reports the aggregate skipped-request count after execution.

Merge Risk: Low · up to 7f9c3

Some scans can silently stop generating HTTP requests after an unresolved variable, and reused fuzz rules can remain skipped after their variables become available. These are bounded risks, but both should be fixed or explicitly accepted before merging.

Full details: Title check

Explanation

The title "Quiet unresolved-variable skips and summarize at scan end" matches the main change in the changeset. The PR mutes per-request warnings for unresolved-variable skips by default, counts skipped requests through the new UnresolvedCounter interface, and prints one summary at scan end. The title is specific and does not use vague terms. It omits the new -log-unresolved opt-in flag, which is a secondary detail.

Full details: Out of Scope Changes check

Explanation

The changed code and tests support Issue #3386. The counter interface, CLI option, shared skip helper, protocol integrations, fuzz handling, error sentinel, and tests all implement unresolved-variable skip reporting or its verification. No unrelated change is demonstrated.

Full details: Linked Issues check

Explanation

Issue #3386 requires quieter unresolved-variable logging, a skipped-request count, and a verbose-mode toggle. The changes implement these requirements with unresolvedvars.Skip, UnresolvedCounter, the end-of-scan runner summary, Options.LogUnresolved, and -log-unresolved. The changes also add tests for error classification and counter behavior. However, the issue asks for an investigation of variable evaluation order for the cited https://{{user}}... URL parsing warning. The reviewed changes classify unresolved errors but provide no focused test or code evidence that establishes or fixes this parsing behavior.

Resolution

Add a focused regression test for the cited self-contained URL case. Document the evaluation order and change the request path if needed so an unresolved variable is classified as an unresolved skip instead of producing the raw URL parse warning.

source-compatible for existing custom implementations. Remove
IncrementSkippedUnresolved and SkippedUnresolved from Progress, and introduce a
separate optional capability interface for unresolved-skip tracking; update
callers to use a type assertion before invoking those methods.

In `@pkg/protocols/common/unresolvedvars/unresolvedvars.go`:
- Around line 11-19: Replace the message-substring check in unresolvedvars.Is
with identity-based classification using a sentinel or typed
unresolved-variables error and errors.Is/errors.As. Update the producers and
wrapped-error paths to preserve that identity, while keeping nil and unrelated
errors returning false. Add a regression test proving an unrelated error
containing “unresolved variables” is not classified as a skip.
