Adds the `nested_containers` bottle flag. On the macOS backend it starts a rootless podman service inside the bottle and exposes its Docker-compatible API socket, so the agent still runs `docker` and `docker compose`. No host daemon socket is mounted and the guest gains no capabilities; backends that cannot run a guest-local engine reject the flag in the shared prepare template rather than ignoring it. Podman rather than rootless Docker because Apple Container's capability bounding set omits CAP_SYS_ADMIN, which the kernel requires to write a multi-range uid_map via newuidmap. With no subordinate UID range podman falls back to a single-UID self-mapping an unprivileged process may write itself, so the image build strips /etc/subuid and /etc/subgid entries rather than adding them. That mapping is also why nested containers are not an isolation layer: root inside one is the agent user outside it. They are a build/test convenience; the bottle remains the boundary. Ports the spike branch onto main, renaming docker_access — it implied Docker and granted access to nothing on the host — and drops podman from the derived layer now that every built-in image ships it (#451).

Research notes
Investigations into a question or a design space — landscape surveys,
tradeoff analyses, "should we do X or Y," assessments of an approach
before (or instead of) committing it to a PRD. A research note is where
the thinking lives; a PRD is where a decided feature lives, and a
decision record is where a settled choice lives (see
../README.md for picking between them).
Notes are opinionated. They reach a conclusion rather than dumping a neutral survey — the point is to move a decision forward and leave a durable record of why it went the way it did.
Naming
kebab-case-topic.md, named by subject and not numbered (unlike
PRDs and decision records). Pick a name that says what was
investigated: bash-vs-python-vs-go.md, pipelock-assessment.md,
issue-tracking-vs-in-repo-decision-history.md.
Shape (freeform)
There's no fixed template — use whatever structure fits the question. In practice most notes share a loose shape:
- Open with the question — a sentence or two on what's being investigated and why it came up.
- Lead with the verdict — a
## Summarynear the top stating the conclusion, so a reader gets the answer without reading the whole thing. - Then the analysis — whatever the argument needs: comparison tables, per-option sections, failure-mode walkthroughs, the axes that actually matter.
- End with a recommendation when the note exists to drive a decision.
Keep the reasoning self-contained and grounded: cite sources, link files and PRDs, and prefer concrete evidence from this repo over generic claims — a note should stand on its own without a chat log or a Gitea thread. When a note's recommendation gets acted on, capture the resulting decision in a PRD or a decision record; the note stays as the "why we looked into it," not the system of record for the choice.
