What

Stop the claude-code executor from re-reading only system-prompt.md (ignoring prompt_files) and route its per-turn prompt through the ONE canonical build_system_prompt — keeping the load-bearing hot-reload.

Why (task #76)

_build_system_prompt called get_system_prompt(config_path), which reads ONLY system-prompt.md and ignores config.yaml prompt_files. The concierge is the one workspace that declares prompt_files, so it booted identity-less — the per-runtime drift this task closes. The invariant is: ONE source of truth (the prompt_files-honoring base builder); no executor ignoring prompt_files.

Hot-reload reconciliation (the key decision)

The claude-code executor's per-turn re-read of /configs/system-prompt.md is load-bearing: it lets a freshly delivered/edited prompt take effect without a restart (proven on the e2e-concierge-proof org).

I kept the file as a live source but made the SSOT builder the single resolution path: _build_system_prompt now calls build_system_prompt(config_path, …, prompt_files=self.prompt_files) per turn, reading from disk each time. So hot-reload is preserved AND prompt_files is honored — the build lives in ONE place. build_system_prompt already includes the base platform identity + A2A + HMA, so those are no longer re-appended by the executor (no duplication); only the claude-code-specific get_display_instructions() is appended (it is not part of the base build). If the builder is unavailable (stubbed test runtime), it falls back to the base-published config.system_prompt (built by the same builder), so the executor never boots prompt-less.

setup() now publishes config.system_prompt via the same builder (boot value + threaded into the executor as the hot-reload fallback; prompt_files/workspace_id are threaded through). create_executor no longer re-reads system-prompt.md.

Tests

tests/test_system_prompt_ssot.py (new):

test_effective_prompt_honors_prompt_files — declared prompts/concierge.md is loaded, the stale system-prompt.md is NOT (the drift).
test_effective_prompt_hot_reloads_from_disk — editing the declared file changes the next turn's prompt without a restart.
test_legacy_system_prompt_md_still_loads_without_prompt_files — backwards-compat fallback.

tests/conftest.py — adds a molecule_runtime.prompt.build_system_prompt stub (honors prompt_files) + prompt_files/workspace_id on the stub AdapterConfig, mirrored in test_adapter_prevalidate.py's local stub (the real AdapterConfig carries these fields). Removed the three now-unused executor_helpers imports (get_system_prompt, get_a2a_instructions, get_hma_instructions).

Prove-fail verified: reverting _build_system_prompt to the old system-prompt.md-only read makes the concierge identity get shadowed by the stale fallback and the tests fail. Full suite green (171 passed, 1 skipped; baseline was 168 + 1) under the CI-faithful env (pytest + pyyaml, stubbed runtime).

Note: openclaw is intentionally out of scope — its gateway assembles the prompt natively from copied *.md files (no single system_prompt injection point).

The executor built its per-turn system prompt with get_system_prompt(),
which reads ONLY system-prompt.md and IGNORES config.yaml prompt_files —
the drift that left the concierge (the one workspace declaring prompt_files)
identity-less. _build_system_prompt now calls the one canonical
build_system_prompt PER TURN from config_path, so prompt_files is honored
AND a delivered/edited prompt still hot-reloads without a restart (the
load-bearing behavior); only the claude-code-specific display instructions
are appended (a2a/hma now come from the base build, no duplication). setup()
publishes config.system_prompt via the same builder (the boot value +
hot-reload fallback); create_executor no longer re-reads system-prompt.md.

Hot-reload reconciliation: kept the file as a live source but made the SSOT
builder the single resolution path, so no executor ignores prompt_files.

Adds tests proving the effective prompt honors prompt_files (not a
system-prompt.md-only re-read), still hot-reloads from disk, and keeps the
legacy no-prompt_files fallback.

APPROVE: current-head 5-axis review for task #76. Correctness: claude-code now routes setup and per-turn hot-reload prompt construction through the shared build_system_prompt path, preserving prompt_files semantics and avoiding stale system-prompt.md shadowing. Robustness: fallback to the setup-published prompt keeps turns from booting promptless if the builder is unavailable, and tests cover prompt_files plus hot reload. Security: no secret/auth/network surface changes. Performance: per-turn file rebuild preserves existing hot-reload behavior with small prompt-file reads only. Readability: comments are explicit and tests document the SSOT invariant.

REQUEST_CHANGES: independent current-head review for claude-code#185 @ 295aa344b4.

Finding: the hot-reload path is not actually equivalent to the setup-time SSOT prompt when plugins contribute rules/prompts. adapter.py publishes config.system_prompt with build_system_prompt(..., plugin_rules=plugins.rules, plugin_prompts=plugins.prompt_fragments), but claude_sdk_executor.py:817-823 re-builds the per-turn prompt with only config_path/workspace_id/prompt_files and no plugin_rules/plugin_prompts. Because _build_options sends system_prompt=self._build_system_prompt(), the effective turn prompt takes the rebuild path whenever the builder is available and therefore drops plugin prompt fragments instead of falling back to the setup-published prompt.

5-axis summary: correctness/robustness need a fix so hot reload preserves the same builder inputs or otherwise carries plugin fragments into the executor; security/performance are not the concern; readability is mostly clear but the comments currently claim setup and per-turn builds use the same SSOT while their inputs diverge. Tests cover prompt_files and legacy fallback, but not plugin prompt/rule preservation, so this regression is unpinned.

The executor's per-turn hot-reload rebuild now passes plugin_rules and
plugin_prompts through the same canonical build_system_prompt builder that
setup() uses, so a reloaded turn no longer silently drops plugin fragments.

- Capture plugin fragments in setup() and thread them into create_executor().
- Accept and store plugin_rules/plugin_prompts in ClaudeSDKExecutor.
- Pass them through _build_system_prompt() per turn.
- Update the conftest stub to include plugin fragments in its output.
- Add test_hot_reload_preserves_plugin_fragments that fails on current head.

APPROVE: current-head 5-axis review for task #76 claude-code prompt SSOT after the Researcher RC. Correctness: setup and per-turn hot-reload now both call build_system_prompt with prompt_files plus the same plugin_rules/plugin_prompts, so the previous plugin-drop asymmetry is closed while preserving hot reload. Robustness: fallback to the setup-published prompt remains, and tests cover prompt_files, legacy fallback, hot reload, and plugin fragment preservation. Security: no auth/secret/network surface changes. Performance: bounded per-turn prompt-file rebuild matches existing hot-reload behavior. Readability: the SSOT and plugin threading intent are explicit.

APPROVED (independent 5-axis review on current head 01a4aced85).

Correctness: RC 14068 is resolved. The adapter now captures plugin_rules/plugin_prompts from loaded plugins and passes them into both config.system_prompt setup and the executor; the executor hot-reload rebuild calls build_system_prompt with those same plugin fragments, so per-turn prompt rebuild no longer drops them.
Robustness: test_hot_reload_preserves_plugin_fragments covers the prior regression shape and would fail on the old hot-reload path.
Security: no new trust boundary or secret handling changes; plugin prompt content follows the existing loaded-plugin path.
Performance: prompt rebuild cost is unchanged in shape; only the existing plugin fragments are threaded through.
Readability: builder remains the prompt SSOT, with the plugin inputs explicit at the adapter/executor boundary.
