+- cached file findings are keyed by file hash plus config hash so repeat scans skip unchanged files; evaluators that read other files declare them (`checks/support.FileScanDependencies`), and a per-directory digest of those inputs - sibling package sources, go.mod/go.work, resolved target state such as the SDK facade - is computed once per pass and stored with each entry
 - a per-scan file corpus (`internal/codeguard/runner/support/corpus.go`) memoizes the target directory walk, individual file reads, and Go/tree-sitter parses so each file is walked, read, and parsed at most once per scan no matter how many sections inspect it; the quality AI checks share it through the `ListTargetFiles`/`ReadTargetFile`/`ParseGoFile` context hooks rather than re-reading the tree

 Use `codeguard rules` to discover what exists and `codeguard explain <rule-id>` to
 understand why a specific finding failed and what remediation path it expects.
 
+Sections can also carry diagnostics, which describe the scan itself rather than
+your code (for example `scan.file-limit` or `scan.govulncheck.*`). They are not
+rules: they have no `codeguard explain` entry and can never be waived or
+baselined. One of them is `scan.section.panic`: if a section crashes, the
+other sections still run, but that section is reported as `fail` with this
+diagnostic and no findings. Its checks did not run, so the scan exits non-zero
+whichever section it was. The JSON and SARIF reports include the recovered
+panic value (`metadata.panic`) and a short stack excerpt (`evidence`). Please
+include both when you report the bug.
+
+### Target paths and scan diagnostics
+
+Every `targets[].path` must name an existing, readable directory. A relative
+path resolves against the directory holding the config file. `codeguard
+validate` and `codeguard scan` both reject a missing, unreadable, or
+non-directory target path with an error and a non-zero exit, rather than
+scanning nothing and reporting a clean pass. The SDK's `ValidateConfig` checks
+config shape only and does not touch the filesystem. Call `ValidateTargetPaths`
+to run the path check from the SDK. `Run` performs it automatically.
+
+Problems found during the walk itself are reported as section diagnostics,
+not findings, so they cannot be baselined or waived:
+
+- `scan.target-walk` (fail): the walk of a target stopped on an error, such
+  as an unreadable subdirectory, so files under it were not scanned. Every
+  section that finalizes after the failure reports it and fails.
+- `scan.file-read` (warn): a file the walk listed could not be read and was
+  skipped. The first 20 such files are listed individually and the rest are
+  summarised.
+- `scan.file-limit` (warn): the walk stopped at the file-count limit.
+- `scan.section.panic` (fail): the section crashed; see above.

+
+```go
+// codeguard:ignore security.taint.go -- operator-controlled env path for test instrumentation
+```
+
+### Justified gosec directives
+
+Go repositories that already gate on gosec through golangci-lint record each
+reviewed subprocess call site with a justified directive. CodeGuard accepts
+those as inline suppressions of `security.shell-execution`, so the same review
+does not have to be written twice:
+
+```go
+cmd := exec.CommandContext(ctx, "git", args...) //nolint:gosec // fixed git binary; args are tool-built
+
+// #nosec G204 -- the operator explicitly supplies the benchmark binary
+cmd := exec.CommandContext(ctx, binary, args...)
+```
+
+Rules:
+- Go source (`.go`) only.
+- A justification is required: `//nolint:gosec // <reason>` or
+  `#nosec G204 -- <reason>`. A bare `//nolint:gosec`, `//nolint:gosec //`, a
+  bare `#nosec`, or a reason with no letters does not suppress.
+- `//nolint` must list `gosec` explicitly (`//nolint:errcheck,gosec // reason`
+  works; `//nolint:errcheck // reason` and a linter-less `//nolint` do not).
+- The mapping is `G204` (subprocess launched with variable) to
+  `security.shell-execution`, and nothing else. Because `//nolint:gosec`
+  silences every gosec rule, it is also translated only to
+  `security.shell-execution`; `security.taint.go`, secret, private-key, and
+  crypto findings on the same line are still reported. `#nosec` with any other
+  gosec rule ID (for example `G304`) suppresses nothing.
+- A trailing directive covers its own line; a directive on a comment-only line
+  covers the next line. Unlike `codeguard:ignore`, it never covers both.
+- Suppressed findings count as inline suppressions in the report summary and
+  rule statistics; with `--include-suppressed` their `suppression` evidence is
+  `{"kind": "inline", "match": "gosec-justification"}`.
