Task 00: Preserve Ordered Indexed Git Configuration

Acceptance

• Valid GIT_CONFIG_COUNT / GIT_CONFIG_KEY_<n> / GIT_CONFIG_VALUE_<n> blocks from the host, executor, profile, task, and Kandev compose into one contiguous ordered block.
• Higher-precedence entries follow lower-precedence entries. Only the longest exact suffix/prefix overlap is emitted once; arbitrary repeated entries remain untouched.
• A locstat-shaped host block followed by Kandev's two managed credential entries produces count 4, preserves hooks and notes settings, and a real Git commit executes the configured hook.
• Docker retains safe.directory and SSH-to-HTTPS rewrites, while standalone and remote agentctl instance creation do not clobber or duplicate forwarded entries.
• Malformed or unreasonably large blocks fail environment preparation with a sanitized error. internal/repoclone remains intentionally isolated from ambient Git config.

Verification

cd apps/backend && go test ./internal/gitconfigenv ./internal/agentctl/server/config ./internal/agent/runtime/lifecycle ./internal/orchestrator/executor -run 'Test.*(IndexedGitConfig|CollectAgentEnv.*GitConfig|BuildEnvVars.*GitConfig|GitConfigPreservesHook)'

Dependencies

None.

Parallelism

Parallel-safe with Task 01: this task owns environment composition/runtime plumbing while Task 01 owns workspace settings persistence.

Inputs

• The reproduced CollectAgentEnv failure: parent count 2 plus task count 2 returns count 2 instead of 4.
• Existing Docker composition in container.go, remote allowlisting in remote_github_env.go, and managed clone isolation in internal/repoclone.
• Spec scenarios for locstat-shaped hooks/notes preservation and exact boundary overlap.

Output contract

Report the parser validity rules and count bound, precedence and overlap algorithm, every updated merge boundary, real Git subprocess RED/GREEN evidence, executor-specific focused results, confirmed repoclone isolation, files changed, and update task/plan status.
