didericis c69642e568 feat(macos): consolidated per-host gateway for the Apple backend (PRD 0070)
Re-enables the macos-container backend on the shared per-host orchestrator +
gateway, replacing the per-bottle companion container removed in #385. This is
the last backend in PRD 0070's roadmap.

Apple Container 1.0.0 forced three departures from the docker shape, each
verified against the live CLI (findings recorded in the networking spike):

- No `--ip`. The address is DHCP-assigned and knowable only once the container
  runs, so the order inverts: gateway up -> run agent -> read its address ->
  register. The identity token is minted by registration and therefore cannot
  be in the agent's run-time env; it rides the proxy URL applied at
  `container exec` time (bare `--env` names keep it off argv).
- No container DNS. The gateway can only be handed the control plane's IP, so
  the orchestrator starts first and the gateway is pointed at its address.
- No `network connect`. Networks are fixed at run time, so the shared host-only
  network is created up front; per-bottle networks would restart the gateway
  on every launch and defeat the consolidation.

The agent runs with `--cap-drop CAP_NET_RAW`: Apple grants NET_RAW by default,
which would let an agent forge a neighbour's source address on the shared
segment. NET_ADMIN is already absent, so this closes the source-address half of
PRD 0070's attribution invariant.

Verified end-to-end on real Apple Container 1.0.0: both images build, the
control plane comes up healthy, the gateway reaches it by IP, and a registered
agent gets 200 for a host in its routes and 403 for one outside them. Bring-up
is idempotent — a second launch does not churn the singletons.

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 ## Summary near 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.
