# ─── Tool-call block sanitizer (2026-07-17) ────────────────────
# When the chat model emits a <tool_call> block INSIDE its
# explanation field (instead of as a top-level block), the
# existing parse_tool_calls() in call_with_tools does dispatch
# it — but the call's *display* (the raw <tool_call>...</
# tool_call> text) still gets piped through the PTY to the
# browser, which renders it as literal text in the log. The
# user sees the model's intent, not the tool's execution.
#
# We scrub <tool_call>{...}</tool_call> blocks from outgoing
# text frames right before they hit the WebSocket. The blocks
# have ALREADY been dispatched at this point (call_with_tools
# ran before the model wrote them to its stdout), so removing
# them from the user's view is safe — the work is done; we just
# don't want to show the wire format.
#
# This regex is the same as tools._TOOL_CALL_RE. We can't
# import tools from miracle-claw-dashboard without a circular import risk
# (tools -> llm -> ... -> miracle_claw), so we duplicate the
# pattern. If you change one, change the other.

# miracle-claw-dashboard runs as a long-lived daemon (systemd --user unit) and used to
# spew one [relay] / [ws] / [ws→pty] line per byte on stdout. Over a few
# days of normal browser use that filled history/miracle-claw-dashboard.log to 1.7MB
# and made the log unreadable when something actually broke.
#
# We now default to **quiet** mode: per-event debug prints are silenced
# unless the operator passes `--verbose` (or `-v`). Errors (OSError,
# EOF, relay-task crash, ws.send failure) are NOT chatter — they print
# unconditionally because they signal something the operator needs to
# see. The startup banner always prints so the operator can find the
# URL even when the process is launched in a terminal and detached.
#
# `_vlog()` is the only verbosity gate. It does the same `print(..., flush=True)`
# the original code did; it just early-returns when VERBOSE is False.

VERBOSE = False  # set by main() once args are parsed

# Env-var override (read in main()) so the systemd unit can opt into
# verbose logs without changing the unit file every time the CLI default
# flips. Set MILAGRO_VERBOSE=1 in the unit's Environment= to get the old
# per-event chatter back. Useful for live debugging without restarting
# in a TTY.

    """Wrap a recording file and amortize flush() across bursts.

    miracle-claw-dashboard's asciinema .cast writer used to call rec_file.flush()
    on every byte burst that came out of the PTY. During an LLM
    stream that's 50+ fsync()s per second per session — measurable
    CPU, and unnecessary for a debug log. This wrapper buffers writes
    in memory and flushes at most every `flush_interval_s` seconds,
    which is plenty for an operator reading the recording after the
    fact.

    Crash-safety trade-off: a crashed session could lose up to
    `flush_interval_s` of output (the buffer at the moment of crash).
    For a 100ms interval that's at most 5-6 LLM tokens, and the
    alternative is 50+ fsyncs per second. The session-end path
    (rec_file.close() in ws_handler's finally block) always flushes,
    so a clean shutdown loses nothing.

    Usage:
        rec_file = BatchedRecorder(open(path, "w", encoding="utf-8"))
        rec_file.write(line)   # buffer, no fsync
        ...
        rec_file.close()       # flush + close underlying file

    The `write()` API is intentionally the same as a regular file's
    so the call sites in relay_pty and the input handler don't need
    to know whether they're writing to a batched or a plain file.

# via --server-chain. The chain is JSON-encoded so the format can
# evolve without versioning; the parser in mclaw is tolerant of bad
# input and falls back to the customer chain rather than crashing
# the chat session.
#
# Import is deferred to inside _spawn_mlg_for_session (below) so the
# import error surfaces in a context where we can show it cleanly
# in the browser, not at miracle-claw-dashboard startup. If llm.py is missing,
# miracle-claw-dashboard still boots and serves the static dashboard — the chat
# is the only thing that breaks.

    None if the chain can't be resolved (in which case the child
    falls back to its default chain). Never raises — the caller is
    in a code path that has to keep going regardless.

    Resolution order:
      1. The principal's tier (from /v1/users/me, set by _check_token).
         This is the source of truth — the user's real, server-resolved
         tier (with the priority chain and canonicalization already
         applied server-side).
      2. The local profile's tier (profile.tier()) — but ONLY when
         the principal's tier is the literal "local" (the dev/admin
         escape hatch, set by the master-key path in _check_token).
         A master-key call has tier="local" because there's no user
         to attribute the request to, but the developer may have
         a richer tier cached in their profile from a previous real
         login. In that case we honor the profile.
         For None / empty tier, we DO NOT fall back to the profile —
         a missing tier means "I don't know", and the conservative
         default is the customer chain. Falling back to the profile
         in that case picks up a stale "team" (legacy alias for
         enterprise) or a never-cleared dev value and silently
         over-promises a real customer.

    The decision tree (Phase 5 PR 2, simplified 2026-07-17):

      1. If the principal is a real MAIC user (via='maic') with
         a raw token, the child runs under the user's JWT.
         MILAGRO_API_KEY is OVERWRITTEN (not merged) to the JWT;
         any inherited master key is dropped. MILAGRO_USER_ID is
         removed (the JWT's 'sub' claim carries the user_id;
         MAIC's authenticate() reads it directly — no advisory
         X-User-Id header needed).

      2. Otherwise (master-key principal, no token, or legacy
         static --token), the legacy path: MILAGRO_USER_ID is
         set to the principal's user_id (advisory), and
         MILAGRO_API_KEY is inherited from parent_env or, if
         absent, from ~/.config/secrets/milagro.env.

    2026-07-17 auth rewrite (Section 0.7 of AGENT_NOTES, port
    from office bot): the JWT path used to be opt-in via
    `MILAGRO_BROWSER_USE_USER_JWT=1`. After the rewrite, the
    JWT path is the DEFAULT for any real MAIC user — the
    opt-in flag is now an escape hatch for the case where
    you explicitly want the master-key path. The reasoning:
    the master-key path was a workaround for the "we don't
    have a per-user JWT yet" case, but the auth rewrite
    means the JWT is always available after a real login.
    Falling back to the master key for a real user would
    just route their requests through the wrong principal.

    Why still expose the opt-in: tests and the old
    `MILAGRO_BROWSER_USE_USER_JWT=0` escape hatch. Some
    internal flows (e.g. the "system" user that miracle-claw-dashboard
    runs as when no one's logged in) explicitly want the
    master key, not a JWT.

    Why extracted: the spawn block is in the middle of a forking
    handler; testing it requires forking a real subprocess. By
    isolating the env-construction here, the tests can just call
    _build_child_env() with stub inputs and assert on the result.

    Returns: a NEW dict (does not mutate parent_env or secrets_path).
    Callers in the spawn block should os.environ.update(...) with
    the result.

    # The child mclaw process calls auth.me() → auth.current_token()
    # which reads ~/.miracle_claw/user_session.json. Without this
    # file the child prompts for login even though the browser user
    # is already authenticated — the browser JWT lives in
    # sessionStorage, not on disk.
    #
    # We write the JWT from the principal (validated by MAIC's
    # /v1/users/me lookup in _check_token) to the session file so
    # the child mclaw finds a valid session and skips the login prompt.
    #
    # 2026-07-17 auth rewrite (Section 0.7 of AGENT_NOTES, port
    # from office bot): the old code wrote a 3-field shape
    # ({token, email, user_id}) that auth.current_user() couldn't
    # read. The fix is to call auth._save_session() with the
    # canonical shape ({token, user, saved_at}) so the child
    # mclaw sees a real user with tier/role/email_verified, not
    # just an opaque token + email.
    #
    # Why not just use the env-var path (MILAGRO_BROWSER_USE_USER_JWT=1)?
    # That path is opt-in for the multi-user case where two
    # browser tabs would race on the on-disk file. For the
    # single-user miracle-claw-dashboard this instance runs, the on-disk file
    # is the canonical place; the env-var path is layered on
    # top for the multi-user case. Both paths should produce
    # the same in-process state.
    #
    # Concurrency: if two browser tabs fork simultaneously with
    # different users, the last writer wins. Acceptable for now —
    # only one user (David/champion) uses this instance.

    # minutes of dashboard use). This is a one-shot, blocking handler
    # that does a non-blocking waitpid loop on each SIGCHLD. Safe to run
    # in the main process — signal handlers in Python are dispatched
    # between bytecode ops; we just need a short handler that returns.
