Extract a call-specific package slice and agent context

Runs unpack_call() and adds a versioned dependency report, compact context in Markdown and JSON, and a validation-plan skeleton.

Usage

slice_call(
  expr,
  output_dir,
  max_depth = 5L,
  overwrite = FALSE,
  dispatch = c("candidates", "static"),
  eval_dispatch = TRUE
)

expr: An unevaluated function call, written as you would normally run it, e.g. predict(fit, newdata = recent_data) or stats::fivenum(x). For S3 generics the dispatch argument can be evaluated once to determine the method, controlled by eval_dispatch.
output_dir: Directory to create the replay project in.
max_depth: Maximum depth to follow same-package internal helpers.
overwrite: Overwrite an existing non-empty output_dir?
dispatch: How unresolved internal S3 dispatch is handled. The default, "candidates", extracts package-internal candidate methods for runtime dispatch; "static" retains static-only extraction.
eval_dispatch: Should a computed (call-shaped) dispatch argument be evaluated once to resolve the S3/S4 method? The default TRUE gives accurate method resolution but executes that piece of your code; the printed output says so whenever it happens. Set FALSE to leave computed dispatch unresolved and analyze the generic itself. Bare symbols are still inspected to resolve dispatch and may force a promise binding; literals are inspected directly.

The insider_unpack result with dependency metadata and class insider_slice added.
