"""Single source of truth for the "Setup a new Claude Code" clipboard payload.

Both the JS-embedded clipboard renderer (`_claude_setup_instructions.jinja`)
and the read-only HTML preview on the dashboard and /install pages consume
these lines. Keep it in Python so there is exactly ONE place that edits.

Placeholders `{server_url}`, `{token}`, `{wheel_filename}`, and `{server_host}`
are substituted at render time. `{wheel_filename}` and `{server_host}` are
pre-substituted server-side via `resolve_lines()`; `{server_url}` and
`{token}` survive into the JS template and are filled in at click time.

`{wheel_filename}` is server-pre-substituted because `uv tool install`
validates the PEP 427 filename *in the URL path* before fetching, so a
stable alias like `agnes.whl` fails with "Must have a version" — we need
the real versioned filename inlined.

`{server_host}` is server-pre-substituted because the `git config` and
`claude plugin marketplace add` lines need the bare host (no scheme), and
the click-time JS only knows the full origin (`{server_url}`).

## Cross-platform trust strategy (when `ca_pem` is supplied)

The trust block (step 0) is the load-bearing piece. Three things bit us in
practice and the design here exists to dodge each one:

1. **rustls rejects the Agnes leaf cert as `CaUsedAsEndEntity`.** The Agnes
   server's self-signed cert is simultaneously its own CA (basicConstraints
   `CA:TRUE`) AND the leaf served on the wire — a setup OpenSSL tolerates
   but webpki/rustls strictly refuses. So `uv tool install <https-url>`
   never works against the Agnes wheel endpoint. We download the wheel via
   curl first (curl uses OpenSSL, accepts the cert), then `uv tool install
   --native-tls --force <local-file>` lets rustls reuse the OS trust store
   for PyPI dependency resolution. No HTTPS hop through rustls touches the
   Agnes host.

2. **`SSL_CERT_FILE` REPLACES the trust store, it doesn't append.** Pointing
   it at `~/.agnes/ca.pem` alone breaks every Python tool that needs to
   reach a public host (PyPI, GitHub) — `da` works fine because it only
   talks to Agnes, but `uv run --with <pkg>` immediately fails with
   `UnknownIssuer`. We materialize a combined bundle at
   `~/.agnes/ca-bundle.pem` (system roots + Agnes CA) and point all
   `SSL_CERT_FILE` / `REQUESTS_CA_BUNDLE` / `GIT_SSL_CAINFO` at it.
   `NODE_EXTRA_CA_CERTS` keeps pointing at just `ca.pem` because Node's
   semantics is *additive* (appends to bundled roots), so a single-cert
   file is correct there.

3. **Bun-compiled `claude` (Windows + macOS distributions) ignores every
   CA env var AND the OS trust store for marketplace HTTPS.** On macOS
   arm64 the binary at `~/.local/bin/claude` is a Mach-O with a `__BUN`
   segment (single-file `bun build --compile`); on Windows claude.exe is
   the same shape. `strings` shows the binary recognizes
   `NODE_EXTRA_CA_CERTS`, `SSL_CERT_FILE`, `REQUESTS_CA_BUNDLE`,
   `CURL_CA_BUNDLE` (including a "NODE_EXTRA_CA_CERTS detected" log
   string), but in practice the values never reach the TLS context — a
   known limitation of Bun's compiled-binary HTTPS path. Registering the
   cert in the OS trust store (Windows: `certutil -user -addstore Root`;
   macOS: `security add-trusted-cert`; Linux: `update-ca-certificates` /
   `update-ca-trust`) doesn't fix it on Windows or macOS either — the
   binary's bundled CA list isn't refreshable from the OS store.

   So the marketplace step always uses system `git clone` regardless of
   platform — system git honors `GIT_SSL_CAINFO` from the combined bundle
   in step 0(d). We tried having Linux attempt direct HTTPS first (where
   node-based claude DOES respect `NODE_EXTRA_CA_CERTS`), but `claude
   plugin marketplace add <https-url>` is broken end-to-end on every
   distribution: it does succeed at downloading the marketplace.json, but
   stores it as a single file. The plugin entries' `source: "./plugins/<name>"`
   paths are then resolved as local filesystem paths against that file's
   parent dir — and the plugin tree obviously isn't there. Only the clone
   path produces a real directory tree that `plugin install` can read.

   The OS trust-store registration in (c) is still done on all three
   platforms because it's needed for *non-claude* native tools — e.g.
   the system git fetch path itself (Schannel on Windows, Security
   framework on macOS) trusts via the OS store, not via env vars.

   Marketplace refresh: after the initial clone, `agnes refresh-marketplace`
   incrementally `git pull`s against the same clone and runs `claude plugin
   marketplace update agnes`. Credentials are injected per-pull via a
   one-shot git credential helper (PAT from `~/.config/agnes/token.json`)
   so the cloned repo's `origin` URL stays PAT-free at rest. The
   SessionStart hook (installed by `agnes init`) calls refresh-marketplace
   on every Claude Code session so changes server-side propagate
   automatically.

## Step ordering

The numbered steps are arranged so that:
  - All installation work (CLI, plugins) happens first, in one go.
  - `agnes init` is mandatory — it bundles auth, workspace bootstrap,
    CLAUDE.md fetch, and Claude Code SessionStart/End hooks into one
    non-interactive call. Replaces the old `agnes auth import-token` +
    `agnes auth whoami` pair.
  - `agnes diagnose` runs late so it doubles as a final smoke test after
    plugins are in place, instead of gating them. It is also the last
    step before Confirm — the whole prompt is non-interactive, no
    decision questions for the user.

Layout:
  0  TLS trust block (only when ca_pem is supplied)
  1  Install CLI
  2  agnes init (auth + workspace bootstrap)
  3  agnes catalog (smoke verify)
  4  Pre-flight: git + claude
  5  Marketplace (always, even with empty served stack)
  6  MCP servers (Atlassian Remote MCP)
  7  Diagnose
  8  Confirm

The combined-bundle source uses a fallback chain so the prompt still works
on machines without the system Python `certifi`: we try (a) `python3 -c
'import certifi'`, (b) the platform's curl/openssl bundle path, (c)
`uv run --with certifi` as a network last-resort. The user explicitly
permitted that fallback chain — it's not improvising-around-a-TLS-error.

    Emitted only when the server has a non-publicly-trusted cert. Does four
    things in a single numbered block (see module docstring for the full
    rationale):

      (a) Detect platform (Windows Git Bash / macOS / Linux) and pick the
          shell rc file that the user's login shell actually reads.
          `$SHELL`-driven, NOT existence-of-rc-driven — old setups put a
          legacy `.bashrc` next to a default zsh shell on macOS, and the
          `[ -f .bashrc ]` heuristic silently writes to the wrong file.
      (b) Write the cert PEM to `~/.agnes/ca.pem` via single-quoted heredoc
          (so `$` / backtick chars in real-world certs never shell-expand).
      (c) Register the cert in the OS trust store (so native binaries that
          bypass our env vars — claude.exe, system git's Schannel backend,
          Python apps using `truststore` — still trust the host).
          Idempotent: re-running just re-affirms the entry.
      (d) Build a *combined* CA bundle (system roots + Agnes CA) at
          `~/.agnes/ca-bundle.pem`, with a fallback chain for the system
          roots source. Persist `SSL_CERT_FILE` / `REQUESTS_CA_BUNDLE` /
          `GIT_SSL_CAINFO` pointing at the bundle, plus
          `NODE_EXTRA_CA_CERTS` pointing at just `ca.pem` (Node
          appends-not-replaces). Persistence is idempotent via a grep
          guard for the `AGNES_CA_PEM_TRUST` marker.

    `claude plugin marketplace add` (and our git-clone fallback) shells out

    binary on either side fails the step with a confusing error. We check
    both here so the user gets a single clear "install X" message instead

    Cross-platform install commands cover the three supported workstation

        with Windows 10 1809+ and Windows 11; non-interactive with --silent.
      - Linux: apt or dnf, depending on distro family.

    than vendoring an install one-liner — Anthropic ships per-platform
    installers (npm on Linux, native binary on macOS/Windows) and the

def _marketplace_block(
    plugin_install_names: list[str],
    step_num: str,
) -> list[str]:
    """Build the marketplace + plugin-install block.

    `plugin_install_names` may be empty: registering the per-user
    marketplace clone with Claude Code is useful even when the operator
    has zero plugin grants, because it pre-wires the SessionStart hook
    and the grant flow — admin grants land on the next Claude Code
    session without re-running setup. The block copy adapts for the
    empty case so the comment-bullet doesn't promise plugin installs
    that won't happen.

    `step_num` is parameterized because step ordering shifted between
    layouts (this block now runs before diagnose/skills, so it's step 5
    instead of the old step 7).

    The whole block is one CLI invocation: ``agnes refresh-marketplace
    --bootstrap``. The CLI handles clone + PAT-strip + chmod + register-
    with-Claude + auto-install-from-manifest internally. This is what
    used to be a 15-line shell sequence inline; pulling it into the CLI
    bought:

      1. **Claude Code permission gate friendliness.** The agent-driven
         onboarding flow inside Claude Code denies ``rm -rf`` by default;
         the inline script tripped on it. Wrapping the destructive prep
         inside agnes lets the CLI's already-trusted permission grant
         cover it (Python ``shutil.rmtree`` doesn't pattern-match the
         shell ``rm -rf`` block).
      2. **Idempotence without inline ``rm``.** Re-running the install
         prompt over an existing clone now does fetch+reset under the
         hood (no destructive cleanup needed). The prompt's "safe to
         re-run" promise holds without forcing the operator to delete
         anything by hand.
      3. **One source of truth.** ``agnes refresh-marketplace`` is also
         the SessionStart hook command, so install + refresh share the
         same code path — version-aware reconcile, hook JSON output,
         credential helper PAT injection, all consistent.

    Why always clone (with the CLI doing it) instead of trying direct
    HTTPS marketplace add first? ``claude plugin marketplace add
    <https-url>`` does succeed against our ``/marketplace.git/`` endpoint
    (returns 200 + JSON), but Claude Code stores the response as a
    single-file marketplace and resolves plugin ``source:
    "./plugins/<name>"`` paths as local filesystem refs — so the
    subsequent ``claude plugin install`` looks for plugin trees at
    ``<marketplace-dir>/plugins/<name>/`` and 404s because the dir is a
    file. Only the git-clone path produces a real directory tree with
    plugin contents in place. Broken end-to-end on every Claude Code
    distribution; cloning is the only reliable install path.

    TLS handling for the in-binary ``git clone`` is fully covered by the
    cross-platform trust block (step 0) when the server's cert needs
    bootstrapping (`ca_pem` non-empty), and by the OS trust store when
    the cert is publicly-trusted. There used to be a legacy fallback
    here that emitted a host-scoped ``git config http.<host>.sslVerify
    false`` line for the ``AGNES_DEBUG_AUTH`` path; that's gone — it
    masked operator misconfigurations (a ``self_signed_tls=True``
    instance without ``/data/state/certs/fullchain.pem`` on disk) and
    its ``sslVerify=false`` shell command tripped Claude Code auto-mode
    classifiers. Operators serving a self-signed or private-CA cert
    must place the fullchain at ``AGNES_TLS_FULLCHAIN_PATH`` (default
    ``/data/state/certs/fullchain.pem``) so step 0 can read it via
    ``_read_agnes_ca_pem``.
