+"""P3-INERT build -> verify subgraph TOPOLOGY (design §3.3, §7.1 P3).
+
+This module is the **wiring topology** for the Plane-2 build -> verify stage::
+
+    ... -> REVIEW (route "build") -> BUILD -> VERIFY -> {approved | build | parked}
+
+It produces the BUILD node, the VERIFY node, and the
+:func:`route_after_verify` conditional-edge function so the Integrate phase can
+hang them off :func:`agent_team.graph.build_graph` as a subgraph reachable from
+the review loop's ``"build"`` route. It assembles NOTHING by itself: it does not
+call :func:`agent_team.graph.build_graph`, and the production default pipeline
+stays P2 (clarify -> plan -> review). Hooking this subgraph in is a deliberate,
+opt-in Integrate-phase edit.
+
+==============================  INERT / HARD-GATE  ==========================
+P3 (builders + verifier) is HARD-GATED behind ``/sh-security-review`` + a
+GPT-4.1 cross-review of the §3.3.2 CI apply/verify trust boundary BEFORE it goes
+live. This module is TOPOLOGY + SEAMS ONLY and MUST stay INERT:
+
+  * **No live CI.** The VERIFY node consumes an INJECTED ``ci_result`` seam — a
+    fetcher callable that, given the task state, returns the authenticated CI
+    conclusion as DATA (exactly what :func:`agent_team.ci_gate.evaluate_ci_gate`
+    expects). The DEFAULT fetcher returns ``None`` (the current pre-live-CI
+    reality). It performs NO live CI dispatch, NO OIDC, NO network to GitHub
+    Actions, NO ``git``/patch apply, and NO filesystem mutation.
+  * **Fail-safe verdict.** With no ``ci_result`` (the default), the pure-code
+    gate (:mod:`agent_team.ci_gate`) returns ``BLOCK`` — there is no
+    authenticated pass to be had — and :func:`route_after_verify` routes the
+    task to PARKED. The pipeline NEVER fabricates a pass; the gate is the sole
+    pass authority.
+  * **LLM stays a fix-proposer.** The verifier's LLM seam
+    (:data:`agent_team.nodes.verifier.FixAdvisor`) is consulted ONLY on a
+    failure to author a fix hint. It is structurally incapable of flipping the
+    verdict to pass (the verdict is computed first, by the gate, and is never
+    read back from the proposer — see :mod:`agent_team.nodes.verifier_llm`).
+
+The live apply/verify path (the gated wiring of a real diff builder + a real CI
+result fetcher) is held for the separate security-review + cross-review gate and
+is NOT shipped or enabled here. :func:`bind_diff_builder` and
+:func:`bind_ci_result_fetcher` are the injection points a leaf will use to bind
+those real seams once the gate clears.
+============================================================================
+
+What this module owns (topology + seams only):
+
+* :data:`APPROVED_ROUTE` / :data:`BUILD_ROUTE` / :data:`PARKED_ROUTE` — the
+  route ids :func:`route_after_verify` returns. ``BUILD_ROUTE`` /
+  ``PARKED_ROUTE`` mirror :data:`agent_team.graph.BUILD_ROUTE` /
+  :data:`agent_team.graph.PARKED_ROUTE` by VALUE so the conditional-edge map the
+  Integrate phase builds matches without this module importing ``graph`` (which
+  would be a wiring import cycle).
+* :func:`make_build_node` — factory producing the single-argument BUILD node,
+  threading an injectable :class:`~agent_team.nodes.builders.DiffBuilder` into
+  :func:`agent_team.nodes.builders.builders_node`.
+* :func:`make_verify_node` — factory producing the single-argument VERIFY node,
+  threading an injectable ``ci_result`` fetcher into
+  :func:`agent_team.nodes.verifier.verifier_node` (default fetcher -> ``None``).
+* :func:`route_after_verify` — the LangGraph conditional-edge function that
+  reads the verdict the VERIFY node recorded and returns the next route id.
+* :func:`bind_diff_builder` / :func:`bind_ci_result_fetcher` — the gated-live
+  injection points (held for the security gate).
+
+It imports the committed node + foundation contracts verbatim and redefines none
+of them. No SDK is imported at module top (deferred discipline mirroring
+:func:`agent_team.graph.build_sqlite_checkpointer`); it is fully unit-testable
+with no network.

+"""Live Claude-Code-on-the-Mac delivery wiring (design §3.3.1, §7.1 P4, D10).
+
+The :mod:`agent_team.transport.claude_code_adapter` module ships the §3.3.1
+transport contract with a dependency-injected ``delivery`` seam: the adapter
+renders the question-set into a prompt body and hands it to a sink called as
+``delivery(session_hint=..., prompt=...) -> str`` whose job is to surface the
+prompt inside a Claude-Code session and return the Claude **session id** used as
+the ``channel_ref`` locator. The foundation's default sink refuses to act so
+nothing ships provisioned; this module supplies the **production** sink, backed
+by a local **file drop** the Mac harness reads, that the P4 (Claude-Code) live
+wiring injects.
+
+Channel model (file drop)
+-------------------------
+The R720 box has no standing write path into Adam's interactive Claude-Code
+session, so delivery is **SSH-invoked from the Mac side** (D10). The live sink
+writes the rendered prompt to a drop directory on the Mac filesystem; the
+Claude-Code harness polls that directory, surfaces the prompt inline, and Adam
+answers it. The sink returns the Claude **session id** (the file stem, derived
+from the embedded ``question_id``) which §3.3.1 names as this transport's
+``channel_ref`` locator. The answer travels back the same way: the harness drops
+an answer file the box reads and feeds to
+:meth:`ClaudeCodeAdapter.parse_answer`.
+
+Deferred / injected I/O (mirrors :func:`agent_team.graph.build_sqlite_checkpointer`)
+-----------------------------------------------------------------------------------
+All filesystem access is injected or deferred so this module imports cleanly in
+pre-deploy / test environments and is unit-testable with fakes:
+
+* the prompt-writer and answer-reader are injected callables (``writer`` /
+  ``reader``) defaulting to thin wrappers over the local filesystem; and
+* the standard-library ``pathlib`` import is the only hard dependency — there is
+  no SDK, network, SSH, or secret touched here. A missing / unwritable drop
+  directory raises a clear :class:`ClaudeCodeDeliveryError` so a misconfigured
+  deploy fails loudly rather than silently reporting a delivery that never
+  reached Adam.
+
+Scope (P2 default; P3 inert)
+----------------------------
+This is the human-in-the-loop *question delivery* path used by the production
+P2 (clarify -> plan -> review) pipeline. It performs no CI, OIDC, git/patch
+apply, or network calls; the P3 builder/verifier apply-verify workflow is held
+for a separate review gate and is neither shipped nor enabled here.

+"""GitHub-issue INTAKE poller: a labeled issue becomes a pipeline task (§3.3.1).
+
+This is the *inbound front door* for the GitHub transport. Where
+:mod:`agent_team.transport.github_adapter` delivers clarifier question-sets
+*outbound* (and parses answers back), this leaf runs the other direction: it
+polls a repository for open issues carrying a configured label and turns each
+not-yet-ingested issue into one pipeline task by calling the coordinator's
+intake entry,
+:meth:`agent_team.coordinator.Coordinator.start_task` (``task_text=<issue
+title+body>``, ``transport_name="github"``).
+
+The shape mirrors the slack_listener seam: everything network/SDK is
+**injected** so the poller is fully unit-testable with no GitHub SDK and no
+socket:
+
+* ``client`` is a small :class:`GithubIssueClient` protocol:
+  ``list_open_issues(label) -> iterable of issue mappings``. Production wires a
+  thin client over the GitHub REST API (deferred import, see
+  :func:`build_default_issue_client`); tests pass an in-memory fake.
+* ``coordinator`` is anything exposing ``start_task(task_text=...,
+  transport_name=...)``: the live :class:`~agent_team.coordinator.Coordinator`
+  in production, a stub in tests. No model or transport is touched here.
+
+De-duplication (P3 scope note):
+    The poller tracks already-ingested issue ids in an **in-memory** set, so a
+    re-poll over the same open issue does not start a second task. This is
+    deliberately simple for now: it does NOT survive a process restart. Durable
+    de-dup (a ledger table of ingested issue ids, mirroring the
+    ``pending_questions`` discipline) is a FOLLOW-UP and is intentionally not
+    shipped here. After a restart an already-ingested-but-still-open issue would
+    be re-ingested; document that and treat the in-memory set as a best-effort
+    guard, not a durable contract.
+
+Design constraints honoured here (pre-deployment scaffolding):
+    * **No live infrastructure.** Nothing is provisioned or called at import.
+      The GitHub client is dependency-injected; the default client's SDK/HTTP
+      import is DEFERRED (mirrors
+      :func:`agent_team.graph.build_sqlite_checkpointer` and the slack_listener
+      SDK discipline), so this module imports cleanly with no optional SDK
+      present and the unit tests stay fully hermetic.
+    * **P2 stays the production default; this is OPT-IN and INERT.** This module
+      does no CI, no OIDC, no git/patch apply, and no network to GitHub Actions.
+      It only reads issues and calls the coordinator's existing intake entry.

+"""Live ``requests``-backed GitHub poster (design §3.3.1, §7.1 P4 — GitHub).
+
+The :mod:`agent_team.transport.github_adapter` module ships the §3.3.1 transport
+contract with a dependency-injected ``http_post`` seam: the adapter renders the
+question-set into a Markdown comment body (embedding the
+``<!-- shq:<question_id> -->`` marker so an inbound answer maps back) and hands
+the REST POST to an
+``HttpPost = (url, *, headers, json_body) -> (status, data)`` whose job is to
+perform the real ``POST /repos/{owner}/{repo}/issues/{n}/comments`` and return
+the GitHub comment payload carrying the new comment ``id``. The foundation's
+default ``http_post`` is a stdlib-only (``urllib``) poster invoked only on an
+actual delivery, so nothing ships provisioned; this module supplies the
+**production** poster, backed by a thin ``requests`` session, that the P4 (GitHub)
+live wiring injects.
+
+Why a thin ``requests`` shim (and not PyGithub):
+    The adapter already speaks the GitHub REST API directly — it builds the
+    comments URL, the ``Authorization: Bearer`` / ``X-GitHub-Api-Version``
+    headers, and the ``{"body": ...}`` JSON itself, then hands a plain
+    ``(url, headers, json_body)`` POST to the seam. The live poster therefore
+    only needs a minimal HTTP client, not the full PyGithub object model. A
+    ``requests`` session keeps the shim small and fully mirrors the seam the
+    adapter already accepts.
+
+Deferred import (mirrors :func:`agent_team.graph.build_sqlite_checkpointer` and
+:func:`agent_team.transport.slack_live.build_slack_poster`):
+``requests`` is an optional dependency that may be absent in pre-deploy / test
+environments, so this module imports cleanly without it. The import is deferred
+to the moment a live client is actually constructed, and a missing package
+raises a clear :class:`RuntimeError` so a misconfigured deploy fails loudly
+rather than silently. The token is likewise resolved at build time (falling back
+to ``GITHUB_TOKEN``); a missing token raises a clear :class:`RuntimeError`.
+
+The marker round-trip is owned by the adapter, not the poster: the poster is the
+pure network seam. :meth:`GitHubTransport.post_question` embeds the
+``question_id`` marker in the comment body it hands to this poster, and
+:meth:`GitHubTransport.parse_answer` recovers it from an inbound reply, so the
+``question_id`` survives end-to-end without the poster needing to know about it.
+
+Production-default safety (P2 stays clarify->plan->review): this module is live
+**transport I/O only** for the human gate. It performs exactly one operation —
+post an issue/PR comment — and contains NO CI calls, NO OIDC, NO git/patch
+apply, and NO GitHub Actions network. The P3 builders/verifier live apply/verify
+workflow is held for a separate review gate and is deliberately absent here.

+Claude-Code ``delivery`` seam. These tests prove the contract entirely with
+mocks (no network, no SDK, and the real filesystem is exercised only through
+``tmp_path`` or injected fakes): the sink writes a prompt drop and returns the
+session id, the ``channel_ref`` round-trips the ``question_id`` through a real
+``ClaudeCodeAdapter``, a dropped answer is read back into a ``parse_answer``
+payload that maps to the original question, and an unaddressable / unwritable
+drop fails loudly.
