+## Algorithmic audit
+
+The host normalization itself adds a fixed number of Go invocations per
+launch. The CLI renders a fixed argument list, so quoting and formatting take
+time and space linear in the lengths of the directory and record paths. Go
+dependency inspection and compilation retain their existing roles. The
+findings below concern a pre-existing algorithm on the audited recovery path
+and a new module-selection defect in the smoke recipe.
+
+### Relocate recovery replacements in one pass without merging selectors
+
+**Evidence:** The API-only path in
+[`RecoveryTool`](../../internal/gotool/recovery.go) walks the parsed
+`go.mod` replacements. It calls `modfile.AddReplace` for each relative
+local replacement. In the pinned `golang.org/x/mod` implementation,
+each call scans the entire replacement slice. With `R` total directives
+and `L` relative local directives, relocation visits `O(R × L)` entries,
+and takes quadratic time when all or most entries require relocation.
+This loop predates host normalization and still runs before the new host
+query.
+
+The same loop can panic on a valid module that declares both an unversioned
+and a version-specific replacement for the same dependency. When the
+unversioned directive appears first and uses a relative path, calling
+`AddReplace` with an empty old version treats both directives as matches
+and clears the version-specific entry. The outer loop then visits that
+cleared entry as if it were another relative replacement. In a disposable
+API-only consumer with both forms for ReleaseKit, Go accepted the module
+and validation passed. After a local hook rejected the tag push, ReleaseKit
+saved the publication record, then panicked in `modfile.addReplace`. It
+exited with status 2 instead of reporting the rejected push and a recovery
+handoff.
+
+**Fix:** Rewrite each relative right-hand path on its existing parsed
+directive in one pass, preserving the exact left-hand path and version
+selector. For example, update the typed replacement and its corresponding
+syntax token before formatting. This takes `O(R)` directive visits plus
+the bytes processed for the paths and avoids selector merging. Keep the
+existing relocation policy, the separate synthetic replacement for the
+original module, and the private module lifetime. Add a recovery fixture
+with distinct local destinations for a wildcard and a version-specific
+replacement. Check that the handoff preserves both directives, selects the
+version-specific destination, and reports the original publication status.
+
+### Anchor smoke-check module paths to the intended checkout
+
+**Evidence:** The [multi-module smoke recipe](../../examples/multi-module/README.md)
+replaced `go -C integrations/...` with subshells that run
+`cd integrations/...` before host discovery. A shell with `CDPATH` set can
+resolve these relative names in another checkout. In a disposable probe
+with matching module paths under two directories, the published snippet
+sent both nested checks to the checkout named by `CDPATH` and returned
+success. If the other checkout has valid profiles and tools, the smoke
+result can appear valid for the wrong candidate.
+
+**Fix:** Use `cd ./integrations/ckconfig` and `cd ./integrations/core/v2`,
+or clear `CDPATH` for those two directory changes. The number of lookups is
+already fixed; the change corrects which directory is selected. Verify the
+copyable recipe with a conflicting `CDPATH` entry.
