Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

In `@go/internal/codeintelcli/main_internal_test.go`:
- Around line 949-956: The captureStdout call currently wraps the entire for
loop iterating over commands, causing all stdout from all command invocations to
accumulate before draining, which can block the pipe and hang the test with
large combined output. Move the captureStdout call inside the for loop so that
stdout is captured and drained for each individual command invocation
separately, preventing pipe buffer overflow.

In `@go/internal/geminiprompts/render.go`:
- Around line 125-132: The `PromptPackPath` used in the `syncstate.Artifacts`
call is currently resolving to a location outside of
`go/internal/geminiprompts/`, which violates the prompt-pack location contract.
Update the `PromptPackPath` constant or variable to point to the correct
location within the `go/internal/geminiprompts/` directory so that the artifact
is persisted to the proper location as required by the coding guidelines.

In `@go/internal/policycli/main.go`:
- Around line 497-499: The parseInstallStateFlags function is reusing
errToolConfigRepoRequired when --repo is missing, but this error message
references "tool config command" which is confusing in the install-state
context. Either create a new dedicated error constant for install-state commands
(e.g., errInstallStateRepoRequired) with an appropriate message, or modify the
error message to be generic enough to work for both tool-config and
install-state contexts. Update the error return statement in
parseInstallStateFlags to use the new error or modify the existing error message
to remove tool-config-specific terminology.
- Around line 578-598: The function compactExistingOrCandidatePaths has a
misleading name that implies it checks for file existence, but it only trims
whitespace, cleans paths using filepath.Clean, and removes duplicates. Rename
the function from compactExistingOrCandidatePaths to compactCandidatePaths to
accurately reflect its actual behavior of compacting and deduplicating candidate
paths without performing any existence validation. Remember to update all call
sites where compactExistingOrCandidatePaths is invoked.

In `@go/internal/syncstate/state.go`:
- Around line 128-157: The `LastWrittenUTC` field assignment in the `Artifacts`
function is dead code because this value is always overwritten by
`timestampArtifacts` in the `Upsert` function before the artifacts are
persisted. Remove the `LastWrittenUTC: now,` line from the Artifact struct
initialization within the loop to eliminate the misleading assignment that
suggests these timestamps are authoritative, since they are never actually used
and will be replaced anyway.
- Around line 717-733: The runtimeVersion function currently searches for the
first line matching "version = " across all sections of the pyproject.toml file,
which can incorrectly match version entries from other sections like
[tool.poetry]. Modify the function to scope the version search to only the
[project] section by tracking when the parser enters the [project] table (detect
lines starting with "[project]") and only return the version when found within
that specific section context, ensuring you don't pick up version entries from
unrelated configuration tables.
- Around line 694-715: The repoRelativePath function has a security flaw where
relative input paths like ../../foo bypass validation and return early at line
697 without checking if they escape the repo root. Additionally, the escape
guard using strings.HasPrefix(relative, "..") on line 705 is not separator-aware
and false-positives on directory names starting with literal `..foo`. Fix this
by normalizing both the relative and absolute path branches against repoRoot
using filepath.Rel and filepath.Join, then validate the result against the repo
root boundary using a separator-aware comparison instead of strings.HasPrefix to
ensure paths cannot escape the repo root whether provided as relative or
absolute.
