User story

As a backend developer, I want a short timeboxed spike that validates session resumption with the Claude Agent SDK and pins down our git identity + auth approach, so that Phase 1 design choices are de-risked before we touch runAgent.

Acceptance criteria

Claude SDK `resume` probe

Identify which SDKMessage variant carries session_id (likely system.init or result); document the access path
Verify a second query({ resume: id, prompt, ... }) continues the prior conversation (model recalls prior turn)
Verify whether resume requires the same cwd or works with a different one
Verify the failure mode when the resumed session has expired or been purged server-side (error vs. silently new session)
Verify token cost on resume (does the SDK re-send full history, or just delta?)

Git identity strategy decision

Compare two options:
- (A) Pass GIT_AUTHOR_NAME / GIT_AUTHOR_EMAIL / GIT_COMMITTER_NAME / GIT_COMMITTER_EMAIL via SDK query({ env })
- (B) Enable extensions.worktreeConfig on the cache clone + per-worktree .git/config.worktree
Decide which to adopt; record reasoning

Git auth strategy decision

Compare options:
- GIT_ASKPASS script that echoes the per-agent token
- URL rewrite via -c url.<base>.insteadOf=...
- Per-repo credential.helper
Decide; ensure the chosen approach does not write the token into .git/config

Output

Decisions captured as a comment on the tracking issue (or docs/decisions/persistence.md), referencing this spike
Code spike kept on a throwaway branch — not merged

Out of scope

Implementation of the workdir module (covered by the next story)
Any user-facing change
