Two disciplines apply regardless of language, runtime, or whether you have source:\n\n1. **Runtime truth beats code reading.** Every claim about why the bug happens must come from observed state β never from a plausible story spun from reading code.\n2. **Leave no trace.** Debugging creates artifacts. Every artifact is journaled and removed before you call the task done.\n\nThe rest of this file is a map. **The knowledge is in `references/`.** This file cannot teach you how to debug β it can only tell you which reference will, for your exact situation.\n\n---\n\n# π¨ READ THE REFERENCES. THIS IS NOT OPTIONAL.\n\n> **This skill is intentionally small.** Ninety percent of what you need to know lives in `references/`. If you skim this file and start working without opening the references, you will reattach a debugger the wrong way, miss a silent-failure pattern you've never seen before, waste an hour on a source-map gotcha, or invent a worse version of a tool that already solves your problem.\n>\n> **Every reference below is mandatory when its scenario applies.** \"I know this language\" is not an exemption. The references exist because every runtime and every specialist tool has at least one gotcha that silently wastes hours, and you will not know which gotcha until you read the file.\n>\n> **The gate rule**: before you run a command from a given reference's domain, you must have read that reference in this session. Re-reading across sessions is cheap. Guessing is expensive.\n\n---\n\n## Runtime Setup β MANDATORY READING BEFORE ATTACHING\n\nThe methodology is language-agnostic. The commands to launch, attach, breakpoint, and inspect are not. **Open the matching reference before Phase 0. Not during. Not after.**\n\n| Your runtime isβ¦ | Open this before attaching anything | Non-negotiable becauseβ¦ |\n|---|---|---|\n| Python (CPython, pytest, asyncio, Django, FastAPI) | π **[references/runtimes/python.md](references/runtimes/python.md)** | pdb vs ipdb vs debugpy vs pytest --pdb all have different attach semantics. Async code needs special breakpoint handling. Wrappers like `poetry run` swallow flags. |\n| Node.js / tsx / ts-node / Bun / Deno (running source) | π **[references/runtimes/node.md](references/runtimes/node.md)** | `tsx` + `node inspect` CLI has a **silent source-map failure** β breakpoints by line number do not fire. You will not notice unless you read this first. |\n| Rust (cargo, tokio, panics) | π **[references/runtimes/rust.md](references/runtimes/rust.md)** | Release builds strip symbols. Tokio tasks need `tokio-console`. The borrow checker makes `dbg!` the faster tool most of the time. |\n| Go (goroutines, dlv, pprof, race) | π **[references/runtimes/go.md](references/runtimes/go.md)** | Goroutine leaks and recovered panics are silent by default. `dlv` has a specific port convention. `go test -race` is the first thing to run, not the last. |\n| Native binary / stripped C/C++ / no source | π **[references/runtimes/native-binary.md](references/runtimes/native-binary.md)** | The workflow (triage β dynamic β static β scripted repro) is counterintuitive if you've never done it. `strings -n 8` silently drops short interpolations like `${x}` β read bytes directly for any extraction that matters. macOS adds SIP / Mach-O / lldb specifics that don't apply on Linux. |\n| **Bundled-app binary** (Bun SEA, Node SEA, Deno compile, pkg, nexe, Electron, Tauri, PyInstaller) | π **[references/runtimes/bundled-js-binary.md](references/runtimes/bundled-js-binary.md)** | These look like Mach-O / ELF but their *high-level* source is recoverable with the right per-bundler tool β Ghidra is overkill. Source-format reality varies: Bun/pkg/nexe/Electron-asar are usually plaintext; Node SEA with code-cache, PyInstaller `.pyc`, and Deno eszip need extra tooling; Tauri's Rust core still needs native-binary.md. Workflow: identify bundler β locate bundle β extract with the bundler-specific tool β grep. |\n\n**If you cannot honestly say you just opened the reference for your runtime, open it now.**\n\n> π¨ **Native binary vs bundled binary β check before committing**: `file ./target` calls them both Mach-O / ELF. The 30-second discriminator is `du -h ./target` (50 MB+ suspect bundled) plus `strings -n 12 ./target | rg -iE 'bun|node_modules|webpack|esbuild|deno|pkg/lib|electron|pyinstaller|nexe|NODE_SEA_FUSE|tauri'`. If hits β bundled-js-binary.md. If clean β native-binary.md.\n\n---\n\n## Specialist Tools β ACTIVELY USE WHEN THE SCENARIO FITS\n\nThese are not \"optional extras\". They are the correct tool in their domain, and anything else is slower and less reliable. **If the bug fits the domain, you MUST use the tool. Read the reference first to know how.**\n\n| Tool | Use when | Reference |\n|---|---|---|\n| **Playwright CLI** | Any browser-served web UI bug. Any flow that requires clicking/typing/navigating. Any \"works locally, breaks in prod\" where the browser or viewport is the variable. **For Phase 8 QA of any browser product, you MUST drive a real browser via Playwright β not curl, not imagination.** | π **[references/tools/playwright-cli.md](references/tools/playwright-cli.md)** |\n| **Ghidra** | Any binary without trustworthy source β third-party closed libs, malware, vendored binaries whose behavior contradicts docs, CTF, firmware. **Use Ghidra's decompiler before `strings`/`objdump` guessing. It turns machine code into readable C.** | π **[references/tools/ghidra.md](references/tools/ghidra.md)** |\n| **pwndbg** | Any native binary debugging session. It is GDB with the useful views (registers, stack, disasm, heap) always visible. **If you'd reach for plain `gdb`, reach for `pwndbg` instead β it is strictly a superset.** | π **[references/tools/pwndbg.md](references/tools/pwndbg.md)** |\n| **pwntools** | Any time you need a reproducible interaction with a binary or network service β crafted payloads, exploit automation, fuzz harness, CTF scripting. | π **[references/tools/pwntools.md](references/tools/pwntools.md)** |\n\n**Failing to use these tools in their domain is a process failure, not a stylistic choice.** If the bug is in a browser and you did Phase 8 without Playwright, you are doing it wrong. If the bug is in a stripped binary and you read hex with `xxd`, you are doing it wrong. The references tell you how. Read them.\n\n---\n\n## The Phase Loop β READ THE REFERENCE FOR THE PHASE YOU ARE ENTERING\n\nEach phase has exactly one reference. Read it as you enter the phase β not in advance, not from memory. The references are self-contained and short.\n\n| # | Phase | π Open this when entering |\n|---|---|---|\n| 0 | **Environment assessment** β know the runtime, ports, symbols, env vars, watchers before attaching | [references/methodology/00-setup.md](references/methodology/00-setup.md) |\n| 1 | **Journal setup** β single `.debug-journal.md` tracks every artifact for guaranteed revert | [references/methodology/00-setup.md](references/methodology/00-setup.md) |\n| 2 | **Hypothesis formation** β minimum three, across orthogonal axes, each with distinguishing evidence | [references/methodology/02-investigate.md](references/methodology/02-investigate.md) |\n| 3 | **Parallel investigation** β team mode `debug-squad` when enabled, async subagents otherwise | [references/methodology/02-investigate.md](references/methodology/02-investigate.md) |\n| 4 | **Oracle Triple** β after 2 consecutive failed rounds, spawn three Oracles with orthogonal framings and synthesize | [references/methodology/04-oracle-triple.md](references/methodology/04-oracle-triple.md) |\n| 5 | **User decision escalation** β only when evidence exhausted and the call has policy implications | [references/methodology/05-escalate.md](references/methodology/05-escalate.md) |\n| 6 | **Root cause confirmation** β confirmed only when toggling the suspected cause toggles the bug | [references/methodology/06-fix.md](references/methodology/06-fix.md) |\n| 7 | **TDD fix** β red test first, minimal green, no scope expansion | [references/methodology/06-fix.md](references/methodology/06-fix.md) |\n| 8 | **Manual QA** β actually use the system (tmux for CLI, Playwright for browser, real curl for API, real repro for binary) | [references/methodology/08-qa.md](references/methodology/08-qa.md) |\n| 9 | **Cleanup** β walk the journal, revert every artifact, verify `git diff` shows only fix + test | [references/methodology/09-cleanup.md](references/methodology/09-cleanup.md) |\n| 10 | **Final verification** β four evidence gates before declaring done | [references/methodology/09-cleanup.md](references/methodology/09-cleanup.md) |\n\n**Phase references are short by design.** Reading one takes a minute. Skipping one costs an hour.\n\n### Cross-cutting methodology references\n\nThese are not phases β read them when the situation calls for them:\n\n| Situation | Reference |\n|---|---|\n| The failure is intermittent β fails sometimes, a different test each run, passes in isolation, or only fails in CI | π **[references/methodology/03-flaky-triage.md](references/methodology/03-flaky-triage.md)** β read BEFORE Phase 2; the failure signature usually collapses the search space in one round |\n| You cannot run the actual operation (paid API, blocked network, missing hardware) but still need runtime evidence | π **[references/methodology/partial-runtime-evidence.md](references/methodology/partial-runtime-evidence.md)** |\n| You're about to declare an extraction / audit / reverse-engineering task done and want a skeptical pass | π **[references/methodology/partial-runtime-evidence.md#verification-oracle-pattern-for-non-debug-tasks](references/methodology/partial-runtime-evidence.md#verification-oracle-pattern-for-non-debug-tasks)** (Verification Oracle is *not* the same as Oracle Triple β read the file) |\n\n---\n\n## Non-Negotiable Safety Invariants\n\n\n1. **Runtime state is the only source of truth.** A hypothesis without an observed value is a guess. Do not fix guesses.\n2. **Every debug artifact is journaled before it is created.** Journal-then-modify, not modify-then-remember-maybe.\n3. **Never ship a fix without a failing-first test.** Redβgreen transition required, or the fix is unverified.\n4. **Never declare done on type-check/compile alone.** Types catch declaration bugs. Only running the actual user scenario catches the actual user bug.\n5. **Never ask the user a question that runtime evidence can already answer.** Escalation is for genuine ambiguity.\n6. **Never silently swallow errors while debugging.** If the system swallows errors, that is often the bug itself. Make them loud temporarily; restore at cleanup.\n7. **Never `git commit` from inside this skill.** Commits belong to `/git-master` after the user confirms the fix.\n8. **Never attach without having read the runtime reference.** The gate rule.\n\n\n---\n\n## What to Do Right Now\n\n1. Read the user's bug description.\n2. Identify the runtime.\n3. **Open `references/runtimes/.md`.** Read it.\n4. Identify which specialist tools apply. **Open each matching `references/tools/*.md`.** Read them.\n5. Open `references/methodology/00-setup.md` and start Phase 0.\n6. Follow the phase loop. Read each methodology reference as you enter the phase.\n\n**The references are the skill. This file is an index.**\n\n\nREAD-ONLY ORACLE C β INVARIANT-VIOLATION. Worktree: `/home/cube/projects/richard/.worktrees/nutricoach-v111-impl`. Do not edit files, run the full E2E, or touch production. Latest literal E2E exits 1: `timed out waiting for normal-restart polling`; last completed lifecycle stage is crash after known-message response, update ID 4; replacement child never reports polling-ready. Earlier crash/restart probes worked. Cleanup is complete. Inspect current code/evidence. Enumerate the five most load-bearing assumptions behind this timeout (child really launched, same profile/config, signal means what harness thinks, fake API state survives, prior child fully reaped, offset/recovery ordering, etc.). For each provide exact file:line evidence, the smallest read-only or focused-test query to falsify it, and predicted observable if true vs false. End with the single most decisive query and minimum likely fix seam. No edits.\n\n\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"},"host_pid":1082531,"final_response":"I read this as a read-only invariant audit of the restart timeout - I inspected the lifecycle evidence and traced replacement startup through recovery and polling.\n\n## Key finding\n\nThe replacement child **did launch and contact the same fake API**. Calls 67-70 are its startup:\n\n- `getMe`\n- `getMe`\n- `getChatMember`\n- `sendChatAction`\n\nIt then stopped before command registration, `deleteWebhook`, or `getUpdates` (`.omo/evidence/v1.1.1-stability/disposable-e2e/fake-api-calls.jsonl:67-70`).\n\nMore importantly, `child_adapter_stopped` exists without `child_adapter_ready` (`process-events.jsonl:5`; ready is emitted only at `scripts/dualcoach_v111_disposable_process.py:174-184`). This strongly indicates `adapter.connect()` returned false or raised, and the child exited while the harness continued waiting solely for `getUpdates`.\n\n## Five load-bearing assumptions\n\n### 1. The replacement is the intended child with the same profile/config/runtime identity\n\n**Evidence**\n\n- Every launch receives the same `profile` object and explicit child environment: `scripts/run_dualcoach_v111_disposable_e2e.py:124-173`.\n- The child loads preflight from the explicit `--profile` path and overlays the supplied API URL: `scripts/dualcoach_v111_disposable_process.py:143-163`.\n- Calls 67-70 prove the replacement reached the existing loopback Bot API.\n- The prepared profile is created once at `scripts/run_dualcoach_v111_disposable_e2e.py:653-678`.\n\n**Smallest falsification query**\n\nRun only child startup against the retained pre-update-4 fixture and print:\n\n- PID/argv\n- `preflight.redacted_identity`\n- `HERMES_HOME`\n- `DUALCOACH_PROFILE_PACKAGE`\n- effective `config.extra[\"base_url\"]`\n\nCompare these with the preceding child.\n\n**Observable**\n\n- **True:** identical profile path, config SHA-256, credential identity, package path, and API port; calls continue at sequence 67.\n- **False:** differing hash/path/port, or no calls on the existing fake API.\n\n---\n\n### 2. βWaiting for pollingβ also detects child startup failure\n\nThis assumption is already contradicted by the evidence.\n\n**Evidence**\n\n- `_start_and_wait_for_poll` waits only on an API action future: `scripts/run_dualcoach_v111_disposable_e2e.py:224-246`.\n- It never races that future against `child.wait()` or `child.poll()`.\n- Child stdout and stderr are discarded: `scripts/run_dualcoach_v111_disposable_e2e.py:172-173`.\n- `child_adapter_ready` is written only after successful `adapter.connect()`: `scripts/dualcoach_v111_disposable_process.py:174-181`.\n- Current evidence has `child_adapter_stopped` but no replacement-ready event: `process-events.jsonl:5`.\n\n**Smallest falsification query**\n\nA focused harness test where `_start_child` returns a process that exits nonzero before `getUpdates`. Await `_start_and_wait_for_poll`.\n\n**Observable**\n\n- **True:** it immediately reports the child return code/startup error.\n- **False/current behavior:** it waits 20 seconds and reports `timed out waiting for ... polling`.\n\n---\n\n### 3. The fake Telegram server preserves pending update 4 and action state across children\n\n**Evidence**\n\n- One `FakeTelegramApi` is created and started for the whole lifecycle: `scripts/run_dualcoach_v111_disposable_e2e.py:653,678`.\n- Engine updates and actions are instance-owned lists: `scripts/dualcoach_v111_fake_telegram_engine.py:51-53`.\n- `getUpdates` removes only IDs lower than the requested offset: `dualcoach_v111_fake_telegram_engine.py:328-339`.\n- Observed offsets progress across earlier children as `[0,2,0,3,0,4]`: `.omo/evidence/v1.1.1-stability/disposable-e2e/offsets.json:1`.\n- Calls 67-70 continue the prior action sequence rather than restarting at 1.\n\n**Smallest falsification query**\n\nSnapshot `next_update_id`, pending update IDs, server identity/port, and action count immediately before and after replacement launch.\n\n**Observable**\n\n- **True:** same engine/port, update 4 remains queued, action count advances from 66 to 70.\n- **False:** a new engine/port, empty queue, reset sequence, or update 4 missing.\n\n---\n\n### 4. The update-4 child was fully reaped and released all process-scoped locks\n\n**Evidence**\n\n- The harness waits for the exact fault exit before setting `child = None`: `scripts/run_dualcoach_v111_disposable_e2e.py:797-804`.\n- The fault uses `os._exit(73)`: `scripts/dualcoach_v111_disposable_process.py:54-61,101-118`.\n- Final cleanup reports every child reaped: `.omo/evidence/v1.1.1-stability/disposable-e2e/cleanup.json:1`.\n- Task26 update processing holds a shared `flock` through the update: `gateway/platforms/task26_runtime_authority.py:138-159`; process exit should release it.\n\n**Smallest falsification query**\n\nImmediately after `_await_exit`, assert:\n\n1. `child.poll() == 73`\n2. `/proc/` is absent\n3. a fresh process can acquire the authority lock non-blockingly.\n\n**Observable**\n\n- **True:** PID absent and lock acquisition succeeds.\n- **False:** surviving PID or `LOCK_NB` returns `EWOULDBLOCK`.\n\n---\n\n### 5. Recovery of the response-before-receipt state completes before polling starts\n\nThis is the leading violated production invariant.\n\n**Evidence**\n\n- Startup explicitly runs all nutrition recovery **before** `deleteWebhook` and `start_polling`: `gateway/platforms/telegram.py:3054-3057,3108-3128`.\n- Calls 67-70 correspond to initialization and staff-readiness validation. No later command or polling call appears.\n- Update 4 faults immediately before `GatewayOnboardingPublicationOutbox.record_receipt`: `scripts/dualcoach_v111_disposable_process.py:101-118`.\n- Recovery only commits `RECEIPTED` outbox rows: `telegram_nutrition_onboarding_runtime_publication_transport.py:45-58`.\n- Replay of an existing `DISPATCHING` publication reconstructs authority via `outbox.get`; an authority mismatch can raise before the branch marks it uncertain: `telegram_nutrition_onboarding_runtime_publication_transport.py:322-352`.\n- `recover_waiting_session` invokes publication recovery and then republishes: `telegram_nutrition_onboarding_runtime.py:182-218`.\n- Existing focused coverage tests an idempotent edit and receipt-gate advancement separately, but not this durable `DISPATCHING` startup path: `tests/gateway/test_telegram_publication_recovery.py:105,217`.\n\n**Smallest falsification query**\n\nCreate the exact durable state produced after update 4:\n\n- domain publication `PREPARED`\n- outbox row `DISPATCHING`\n- workflow cursor 2\n- no Telegram receipt\n\nThen instantiate a fresh runtime and call `recover_waiting_session` under a bounded timeout, recording the exception and resulting outbox/domain states.\n\n**Observable**\n\n- **True:** recovery returns, publication becomes safely `UNCERTAIN` or reconciled, and startup reaches `deleteWebhook/getUpdates`.\n- **False/likely:** `outbox.get` raises an authority mismatch or another recovery exception; `adapter.connect()` returns false, producing `child_adapter_stopped` without ready/polling.\n\n## Most decisive query\n\nRace the replacement childβs exit against its first `getUpdates`, while preserving bounded stderr:\n\n```text\nFIRST_COMPLETED(child.wait(), normal_restart_getUpdates_future)\n```\n\nRun only through the update-4 restart boundary, not the full E2E.\n\nPredicted result: **child exit wins**, with the traceback rooted in response-before-receipt startup recovery. That directly distinguishes production recovery failure from fake-server, reaping, configuration, or polling-signal problems.\n\n## Minimum likely fix seam\n\n`gateway/platforms/telegram_nutrition_onboarding_runtime_publication_transport.py:322-352` β the prepared-publication replay path. It should handle an existing `DISPATCHING` authority deterministically without allowing reconstructed render-authority mismatch to abort adapter startup.\n\nSeparately, the harness should eventually race child exit against polling, but that is observability; it does not fix the likely recovery defect.\n\nNo files were edited and no full E2E was run.","run_stats":{"runtime_ms":214367,"turns":11,"tool_calls":65,"output_tokens":10077,"total_tokens":919731,"generation_ms":208042,"tokens_per_second":48,"cost_usd":1.8899400000000002,"cache_hit_rate_last":0.9781788048982598,"cache_hit_rate_run":0.7232640102720375}}
