taodengandClaude <claude-opus-4-8> <noreply@anthropic.com> c377219c1c fix(server): wire CLAUDE_SYSTEM_PROMPT into the composed system prompt (was dead since APPEND_SYSTEM_PROMPT retirement)
The var was read (SYSTEM_PROMPT, server.mjs), documented in the file header as
"appended to all requests", and echoed on /health.systemPrompt — but nothing on
the request path consumed it: extractSystemPrompt() composed only the wrapper +
client system messages. The wiring was lost when APPEND_SYSTEM_PROMPT was
retired, leaving the header comment and the buildCliArgs comment describing
behavior that did not exist (caught by the PR #170 independent reviewer).

Wire, not delete, because:
- the /health `systemPrompt` field is part of the grandfathered B.2 contract
  (ADR 0006, frozen at v3.16.4) — removal would need an ADR; wiring keeps the
  shape and makes the field honest;
- fleet check: no deployment sets the var (Mac prod plist, Oracle systemd unit,
  PI231 /etc/ocp/ocp.env all clean), so wiring changes behavior for NOBODY today;
- with the var unset, appendOperatorPrompt returns its input string unchanged —
  the default path is byte-for-byte identical.

Mechanics: new pure lib/prompt.mjs `appendOperatorPrompt(base, operatorAppend)`
(trimmed; whitespace-only treated as unset so a stray space in a service unit
cannot inject "\n\n " into every request), applied as the LAST segment in both
extractSystemPrompt branches — an operator-wide directive reads as the final
instruction, after client system messages. TUI-mode is untouched (panes keep the
interactive CLI's own system prompt); documented in the README row.

ALIGNMENT.md Rule 2: no cli.js citation applies. No endpoint, header, or wire
field is added or altered; the change affects only the CONTENT OCP passes to the
already-established `--system-prompt` flag (file header § verified v2.1.104),
i.e. OCP-owned prompt composition. /health shape unchanged.

Tests: +3, doubly mutation-proven (unconditional-base revert → 2 failures;
trim removal → 2 failures). Suite 341 passed / 0 failed.

// lib/prompt.mjs — pure operator-append step for the system prompt.
//
// Extracted so the rule is unit-testable (the suite never imports server.mjs — it
// boots a listener). server.mjs composes wrapper + client system messages exactly as
// before, then passes the result through this. With CLAUDE_SYSTEM_PROMPT unset the
// return is the INPUT STRING UNCHANGED — the default path stays byte-for-byte
// identical, which is the repo's bar for touching a request-shaping function.
//
// The operator prompt goes LAST deliberately: a server-wide directive ("answer in
// Chinese") should read as the final instruction, not something a client system
// message overrides by coming later. Whitespace-only values are treated as unset —
// a stray space in a service unit's Environment= line must not inject "\n\n " into
// every request.
