Framing A — OBVIOUS-BUT-MISSED. Give exactly three likely causes ranked, with concise distinguishing evidence and minimal fix. Read-only reasoning; do not modify anything.\n\n<Category_Context name=\"deep\">\nYou are operating in DEEP mode. This is the category reserved for goal-oriented autonomous work on hairy problems that reward thorough exploration and comprehensive solutions.\n\nThe orchestrator chose this category because the task benefits from depth over speed. You should feel empowered to spend the time needed: five to fifteen minutes of silent exploration before the first edit is normal and correct. Rushing to implementation on a deep task is a failure mode, not a feature.\n\n# How deep mode adjusts the base behavior\n\n**Exploration budget: generous.** Read the files you need, trace dependencies both directions, fire 2-5 explore/librarian sub-agents in parallel for broader questions. Build a complete mental model before the first `apply_patch`. Exploration here is an investment, not overhead.\n\n**Goal, not plan.** You receive a GOAL describing the desired outcome. You figure out HOW to achieve it. The orchestrator deliberately did not hand you a step-by-step plan; producing one and asking for approval is not what was asked. Execute.\n\n**Atomic task treatment.** When the goal contains numbered steps or phases, treat them as sub-steps of ONE task and execute them all in this turn. Splitting them across turns is wrong unless they reveal an architectural blocker that requires the user's input. If the \"steps\" turn out to be genuinely independent tasks that should have been separate delegations, flag that in your final message and refuse the ones beyond scope.\n\n**Root cause bias.** Prefer root-cause fixes over symptom fixes. A null check around `foo()` is a symptom fix; fixing whatever causes `foo()` to return unexpected values is the root fix. Trace at least two levels up before settling on an answer. In deep mode, you have permission (and the expectation) to do the deeper fix.\n\n**Ambition scaled to context.** For brand-new greenfield work, be ambitious. Choose strong defaults, avoid AI-slop aesthetics, produce something you would be proud to hand to another senior engineer. For changes in an existing codebase, be surgical and respect the existing patterns; depth does not mean invasiveness.\n\n**Completion bar: full delivery.** \"Simplified version\", \"proof of concept\", and \"you can extend this later\" are not acceptable deliveries for a deep task. The orchestrator routed here specifically for a complete solution. If you hit a genuine blocker (missing secret, design decision only the user can make, three materially different attempts all failed), document it and return; otherwise, finish the task.\n\n**Status cadence: sparse.** The user is not on the other side of this conversation; the orchestrator is, and they will synthesize your progress. Send commentary only at meaningful phase transitions (starting exploration, starting implementation, starting verification, hitting a genuine blocker). Do not narrate every tool call; silence during focused work is expected.\n</Category_Context>"},"host_pid":1353625,"final_response":"I read this as root-cause triage - here are exactly three ranked causes with distinguishing evidence and minimal fixes.\n\n1. **Launcher omitted the external authority writable mounts — direct cause.**  \n   **Evidence:** `--ro-bind / /` covers `/home/cube/.hermes/runtime-authority/...`; the only writable binds are profile, systemd-user, and migration. The failing lock is therefore read-only inside bwrap despite host ext4 being writable.  \n   **Minimal fix:** writable-bind the exact sealed authority root and its credential directory, not the broad Hermes tree.\n\n2. **Authority loading unexpectedly performs a write.**  \n   **Evidence:** `RuntimeAuthoritySource.__init__` unconditionally calls `self.lock_path.chmod(0o600)`, although the existing lock is already `0600`. `authorize()` also opens it with `\"r+\"` despite only taking a shared flock.  \n   **Minimal fix:** validate the existing mode and open the shared lock read-only. This removes needless writes during loading, but the transaction still needs cause #1’s mount because promotion and rollback genuinely mutate authority state.\n\n3. **Tests/rehearsal never reproduced the live mount topology.**  \n   **Evidence:** the launcher test merely asserts that some `--bind` exists; disposable authority tests use writable `tmp_path` storage. The passing 13-case rehearsal therefore did not exercise an external authority beneath the root read-only bind.  \n   **Minimal fix:** add one exact-bwrap integration test with authority outside the three existing writable roots, asserting the real worker reaches authorization and that only the explicitly bound authority paths are writable.","run_stats":{"runtime_ms":135308,"turns":9,"tool_calls":31,"output_tokens":3767,"input_tokens":121167,"cache_read_tokens":461312,"total_tokens":586246,"generation_ms":86332,"tokens_per_second":44,"cost_usd":0.9495009999999999,"cache_hit_rate_last":0.9352292888418882,"cache_hit_rate_run":0.7919804834165696,"token_status":"complete","cost_status":"reported","duration_status":"monotonic"},"task_seq":6,"config_generation":0,"background_mode":"background"}
