You have root access and 900 seconds.\n\nExpose HTTP on port `8080` with this public contract:\n\n- `GET /health` returns HTTP 200 with the exact body `ready`.\n- `POST /jobs/` accepts the raw request body as the job payload and returns HTTP 202.\n- `GET /jobs/` returns JSON containing `id`, `payload`, `status`, `result`, and `attempts`.\n- Completed jobs have `status` equal to `completed`, `result` equal to `processed:` followed by the original payload, and `attempts` equal to `1`.\n\nOpaque work accepted before you arrived is present somewhere on the host. Recover and process it exactly once. Do not discard it, replace it, or invent substitute identifiers.\n\nThe worker lifecycle must be exposed as `job-worker.service` so operations can restart it independently. The complete deployment must start automatically and preserve accepted and completed work across a host reboot.\n\nChoose the implementation, storage, process topology, and tooling yourself. Inspect the host, implement the service, exercise the public contract, and leave it running.\n\n\nThe controller-owned referee is the only authority on completion. Implement and verify the requested outcome on this host, then leave it running. Referee evidence, hidden topology, other competitors, and future events are not available to you.

The relevant pre-existing work is `/var/lib/accepted-jobs/` with three accepted jobs:\n- accepted-alpha-7d3: payload \"alpha\"\n- accepted-beta-91e: payload \"beta\"\n- accepted-gamma-c42: payload \"gamma\"\n\nThese are in \"accepted\" status, meaning they were accepted before I arrived. I need to recover and process them exactly once, preserving their identifiers.\n\nNow let me check what tools are available. This is a NixOS host. Let me check available languages/runtimes for building the HTTP service.\n\nLet me check node, python, go, etc. And systemd setup.\n\nMy plan:\n1. Build an HTTP service with:\n - GET /health -> 200 \"ready\"\n - POST /jobs/ -> accepts raw body as payload, returns 202\n - GET /jobs/ -> JSON with id, payload, status, result, attempts\n - Completed jobs: status=completed, result=\"processed:\"+payload, attempts=1\n\n2. Durable storage so accepted and completed work survives reboot. Store on disk (JSON files) in /var/lib/job-worker/ or similar.\n\n3. Worker lifecycle as `job-worker.service` (systemd unit name). Operations can restart worker independently. So probably separate systemd services: one for the HTTP server (a.service) and one for the worker (job-worker.service). Actually the contract says \"The worker lifecycle must be exposed as job-worker.service\". So the worker is a separate systemd service. The worker processes accepted jobs (transitions accepted -> processing -> completed). The server accepts jobs.\n\nWait, \"The worker lifecycle must be exposed as `job-worker.service` so operations can restart it independently.\" This suggests a systemd unit named `job-worker.service`. Operations can restart the worker independently without restarting the whole deployment. So I should have the HTTP server (front) and worker (back) as separate systemd units. The worker consumes jobs from the accepted queue and completes them.\n\nActually, we could keep it simpler: one systemd unit for the server that includes worker threads, but then the unit name would need to be job-worker? No - the requirement is the worker lifecycle is `job-worker.service`. Let me create two units:\n- `jobber.service` (the HTTP server/front door that accepts jobs and persists them)\n- `job-worker.service` (the worker that processes the accepted queue and completes jobs)\n\nBoth must start automatically on boot and preserve work across reboot. So both should be systemd services with autostart.\n\nLet me design:\n\nStorage: directory `/var/lib/jobber/jobs/`. Each job is a JSON file named `.json` (opaque id could contain chars, so use url-safe encoding... The opaque-id in the path - use as filename. But opaque ids might have slashes. In this task the ids are like \"accepted-alpha-7d3\". User POST /jobs/ - the id is whatever path segment. I'll sanitize filename but keep the exact id in the JSON. Actually safer: store id inside file, but name file by a hash to avoid path traversal. But we also need to look up by id. Keep a mapping. Actually simplest: filename = urlsafe base64? No, let me just use the id but sanitized: replace path-unfriendly chars. Since the referee checks completion via GET /jobs/, the id must map back. I'll use a safe encoding for filenames and store the real id inside. But lookups: GET path id -> need to find file. I'll map id -> filename via encoding (encode id to safe string deterministically). \n\nLet me use: filename = base64url(id) + \".json\". But in Python base64 could have the '-' char which is fine for filename. Actually for read lookups I compute same encoding. Simple and safe. But base64 padding '=' is problematic in filenames. Use urlsafe_b64encode without padding. Fine.\n\nHmm, but simpler: since opaque ids in practice here are alphanumeric with dashes, I can sanitize by replacing '/' and '..' etc. But to be fully robust against path traversal, base64 encoding is best. Let me do base64url without padding.\n\nFor the pre-existing accepted jobs in /var/lib/accepted-jobs/, these are the accepted work to recover. I should migrate them into my job storage and process them. The ids: accepted-alpha-7d3, accepted-beta-91e, accepted-gamma-c42. Their payloads: alpha, beta, gamma. These must be processed to status=completed, result=\"processed:alpha\" etc, attempts=1.\n\nBut wait - the referee is the authority on completion and it presumably POSTed (accepted) these opaque jobs before. So the referee will GET /jobs/ and expect completed. Actually maybe the referee only checks the jobs it knows. The accepted-jobs are the ones pre-created. I must process them.\n\nDesign partitions:\n- Queue directory: `/var/lib/jobber/` or I'll use `/var/lib/jobber/`. Storage perms root ok.\n\nStates: accepted -> processing -> completed. On processing, if worker dies mid-processing, restart should resume. To ensure \"process exactly once\", I need to be careful: when worker takes a job, it should atomically complete it. Since processing is trivial (concatenate \"processed:\"+payload), just set status completed immediately. But to be robust against crash: from accepted, worker marks it processing, then writes result and marks completed. If crash during processing, on restart it can resume. Since operation is idempotent (write result from payload), reprocessing accepted is safe. \"exactly once\" means the completed result recorded once / not duplicated. I'll make the worker process accepted jobs and write completed with attempts=1.\n\nLet me structure storage JSON file per job:\n```\n{\"id\": \"...\", \"payload\": \"...\", \"status\": \"accepted|completed\", \"result\": null or \"processed:...\", \"attempts\": 0 or 1}\n```\n\nServer POST handler: read raw body as payload, create/update job? Contract says \"accepts the raw request body as the job payload and returns HTTP 202\". If job already exists? For opaque ids new. I'll create a new job with status accepted, attempts 0? But completed jobs have attempts=1. So accepted jobs have attempts=0, and processing increments to 1? The worker sets attempts=1 when completing. Let me set accepted jobs attempts=0, completed attempts=1.\n\nWait, but the pre-existing accepted jobs don't have attempts field. They only have id,payload,status. That's fine, I recover them.\n\nWorker: polls queue for accepted jobs, for each:\n- status -> processing (in-memory, not necessary persisted; but durability: if crash mid-processing we might leave as processing forever). To be safe, persist status transitions and on startup move any \"processing\" back to \"accepted\".\n\nGiven operation is quick and local, I'll just persist status and set result. But to show robustness, I'll:\n- In worker, read all files; for any with status \"accepted\", process them.\n\nProcessing: set attempts=1, status=completed, result=\"processed:\"+payload. Write atomically (write tmp then rename).\n\nRace: multiple workers? Only one worker. Use file locking to be safe (single worker service ensures one instance). But systemd restart could overlap with old. Use os-level lock file to avoid two workers. I'll add a lock.\n\nServer accepts job: write file if not exists? The contract: before-arrived accepted jobs already exist in /var/lib/accepted-jobs. Do I migrate them into my storage? The referee might GET /jobs/accepted-alpha-7d3. My server needs to serve those. So yes, I'll populate my storage from those accepted files at startup (recover them). Actually I should import them into storage dir as accepted jobs so server can serve and worker can process.\n\nLet me plan the storage: one directory `/var/lib/jobber/` containing `jobs/` and maybe a lock. On app startup, scan `/var/lib/accepted-jobs/` for files and import any not already in storage (recover exactly once). Import = create job records with same id & payload, status from file (accepted). Then worker processes them.\n\nNow, \"Do not discard it, replace it, or invent substitute identifiers.\" So keep ids exactly: accepted-alpha-7d3 etc.\n\nThe result for these should be result=\"processed:alpha\". Good.\n\nNow what about GET /jobs/ JSON field ordering—not important, but include id, payload, status, result, attempts. \n\nLet me check available runtimes on NixOS.\n\nLet me check python3, node, go.", "details": [ { "format": "unknown", "index": 0, "text": "The", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " \"claux\"", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " file is the ELF binary", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " of the agent itself -", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " irrelevant.

No\n node\n, go, etc. So I'll implement in Python\n using the standard library http.server (no deps)\n. systemd is 261, available.\n\nLet me check `pip` and if any http libs. Python stdlib has http.server. Good, no external deps needed.\n\nLet me now design the implementation.\n\nDirectory structure:\n- `/var/lib/job-worker/` - storage\n - `jobs/` - one JSON per job\n - lock file for worker\n- Migrate `/var/lib/accepted-jobs/*.json` into this storage at server startup.\n\nPython files in `/opt/job-worker/`:\n- `server.py` - HTTP front door on port 8080, accepts jobs, serves GET, health.\n- `worker.py` - scans accepted queue and processes them.\n- Both started as systemd units: `job-worker.service` (worker) and `jobber.service` (server)? \n\nActually requirement: \"The worker lifecycle must be exposed as `job-worker.service`\". Let me create two systemd .service files:\n- `jobber.service` → runs server.py (HTTP) \n- `job-worker.service` → runs worker.py\n\nBoth autostart (default systemd units placed in /etc/systemd/system with systemctl enable). Preserve across reboot = durable disk storage + systemd autostart.\n\nLet me think about how systemd units are configured on NixOS. NixOS normally manages via /etc/nixos but there's plain systemd too. I can just drop .service files in /etc/systemd/system/ and enable. That should work as root.\n\nBut NixOS uses systemd-activat... Actually if user passes systemd.disableUnitDefaults, but default should be fine. Let me just create service files and `systemctl enable`. Let me test.\n\nLet me now write the code.\n\nStorage design: one JSON file per job, named by a safe filename derived from id. Use base64url of id to map safely. Let me define:\n\n```python\nimport base64\ndef fn(id_):\n return base64.urlsafe_b64encode(id_.encode()).decode().rstrip('=') + \".json\"\n```\n\nBut lookups need to know which file maps to which id. Since we store filename = b64(id), we can compute it for any id. But base64 without padding is ambiguous when truncating... We rstrip only trailing '=' which is deterministic for the padded encoding of the full id. Actually urlsafe_b64encode produces padding except when length multiple. For lookup we do same encode → same filename. Since the encode is a function, deterministic. Good. But two different ids could map to the same unpadded string if one is prefix... no, encode is deterministic and injective for given input because we always pad fully then strip. Two different byte strings have different full base64. Stripping padding can't collide because padding only appears at end and we re-add? For decode/lookup we just use the name directly. The name = strip(pad(encode(id))). Two ids could theoretically map to same stripped string? encode(id) includes padding only if necessary; stripping padding: e.g. encode(\"a\")=\"YQ==\"→\"YQ\", encode(\"ab\")=\"YWI=\"→\"YWI\". Different. Could encode(\"abc\")=\"YWJj\"(no pad) vs encode(\"abcd\")? = \"YWJkZA==\"→\"YWJkZA\". Different. Generally bijective for the encode-decode... not guaranteed but collisions are essentially impossible for different input because base64 is injective and padding stripping is only for trailing null-like... Actually two different full base64 strings that differ only in trailing '=' would map differently; the stripped forms differ in content too. I'll not overthink; ids here are safe. I could instead just sanitize the id to a safe filename by replacing any char not in [A-Za-z0-9-_.] with hex escape. That's bijective. Let me do that encoding (percent-style but filesystem-safe). I'll write:\n\n```python\nimport re, urllib.parse\ndef encode(id_):\n return urllib.parse.quote(id_, safe='').replace('%','_') # produce safe\n```\n\nHmm but then decode needed for serving? I can store lookup by filename→id by scanning dir on demand. Given small number of jobs, simplest robust approach: store id inside file, filename = hash/encode. On GET /jobs/, scan storage dir for file whose record id == requested id. That's O(n) but n is tiny. Actually even simpler and fully robust: filename = the id itself but sanitized for path safety, and keep id inside. On GET, encode the requested id to filename and read. Let me just use a reversible filesystem-safe encoding.\n\nI'll use urlsafe_b64encode(id) and store; on get, I need id→filename. I can compute encode(id) deterministic. Scanning is fine too. Let me just compute encode(id) and check existence; also verify. Good enough.\n\nLet me write encode as base64.urlsafe_b64encode(id).decode().rstrip('='). And endpoint: on GET, compute path = jobs_dir / (encode(id)+'.json'); if exists, read and return. For POST, compute same path.\n\nNow the worker: scan jobs_dir for files with status=='accepted', process: set attempts=1, status='completed', result='processed:'+payload. Atomic write (write temp, fsync, rename).\n\nAlso handle resuming: if crash left status='processing', move back to accepted on worker startup. I'll implement statuses accepted/processing/completed. Worker marks processing (persist), then completed.\n\nLet me handle \"exactly once\": use a worker lock (file lock via `with`). And to avoid double processing from overlapping restarts, the lock ensures single worker. Within processing, mark accepted→processing persisted first; if crash, restart resumes processing→accepted→reprocess. Since operation idempotent and result derived from payload, exact-once result preserved.\n\nLet me write server.py.\n\nI'll use http.server.ThreadingHTTPServer with a BaseHTTPRequestHandler.\n\nHandling paths:\n- GET /health → 200 \"ready\"\n- POST /jobs/ → read body as payload, create job status accepted attempts 0 (or whatever), return 202 with empty body (or minimal). \n- GET /jobs/ → 200 JSON\n\nJob create: if not exists, create with id, payload, status='accepted', result=None, attempts=0. If exists... do we overwrite? The contract says accept raw body as payload → likely create. I'll create a new accepted entry (idempotent semantics TBD). I'll write it fresh each POST (overwrite payload & reset). That's fine.\n\nNow, for the pre-existing accepted jobs, server startup should import from /var/lib/accepted-jobs into storage. Let me implement an import on server startup: read all json files in /var/lib/accepted-jobs, ensure stored (won't overwrite an existing completed one? import only if not already in storage). Actually to \"process exactly once\", the server imports them as accepted, then worker processes. But we want recovery \"exactly once\" - import them once. Since import creates them in storage with status accepted (or preserve their status), worker processes. I'll import only if not already present in storage.\n\nLet me now write the code files.\n\nI'll create /opt/jobber/server.py, /opt/jobber/worker.py, a shared storage module maybe. Let me combine.\n\nLet me also make it durable: fsync files.\n\nLet me write.\n\nSTORAGE_DIR = '/var/lib/job-worker/jobs'\nIMPORT_DIR = '/var/lib/accepted-jobs'\n\nNow, systemd units. Let me create two units. The worker must be independent (job-worker.service) so ops can restart it. The server is jobber.service.\n\nLet me write everything.", "details": [ { "format": "unknown", "index": 0, "text": "Only", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": "\n python", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": "3 and\n", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " curl", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": " available", "type": "reasoning.text" }, { "format": "unknown", "index": 0, "text": ".

They\n set `ConditionPathExists=/etc/replaybook/job-api-start` so once I create\n that file, the unit can start. Good.\n\nSo the intended\n design:\n- I create\n `/etc/replaybook/job-api-start` \n which launches the HTTP server on port 8080.\n- I create\n `/etc/replaybook/job-worker-start`\n which launches the worker.\n- The systemd units `job-api.service` and `job-worker.service` already exist and are wired up with proper restart. I just need to enable them (they have [Install] WantedBy=multi-user.target, and are in /etc/systemd/system so presumably enabled? Let me check status).\n\nActually these are symlinks; enabling registers them. Let me check if they're enabled.\n\nAnd there's accepted-job-spool.service (oneshot) that presumably ran at boot to place the accepted jobs into /var/lib/accepted-jobs. Actually the accepted jobs already exist there. Good — that's the \"opaque work accepted before you arrived.\"\n\nSo my plan:\n1. Implement a shared Python storage module + worker + api, or just put python code somewhere (e.g. /var/lib/job-worker/ or /etc/replaybook/ or /opt).\n2. Create the two start scripts.\n3. Use systemd units already present. Enable job-api.service and job-worker.service.\n4. Test the contract.\n\nI need to be careful: The units already exist with [Install] WantedBy=multi-user.target. Are they enabled? Let me check enabled units.\n\nLet me think about where to put the code. I'll put the Python implementation in /etc/replaybook/ alongside, or in /var/lib/job-worker/. The ExecStart is `/bin/sh /etc/replaybook/job-api-start`. So job-api-start is a shell script that in turn runs python. I need python's full path. On nix, /bin/sh and python3. Let me find python3 path.\n\nLet me get absolute paths for python3.\n\nLet me design the storage. I'll create directories:\n- /var/lib/jobstore/jobs/ (durable)\nActually the existing spool uses /var/lib/accepted-jobs. The worker needs to consume those accepted jobs and complete them. \n\nDesign decision on state model and durability:\n\nOption A: Keep single canonical store. The pre-existing accepted jobs in /var/lib/accepted-jobs are the authoritative accepted records. The API should read/write there. The worker processes jobs from there (accepted -> completed) by rewriting the JSON with completed status/result/attempts.\n\nBut the contract says:\n- POST /jobs/ accepts raw body as payload, returns 202. So new jobs should be placed. Where? Could go into the same /var/lib/accepted-jobs queue. That keeps one store. Good.\n- GET /jobs/ returns JSON with id, payload, status, result, attempts.\n\nLet me use /var/lib/accepted-jobs as the canonical job store. Each job = file /var/lib/accepted-jobs/.json containing {\"id\":..., \"payload\":..., \"status\":..., \"result\":..., \"attempts\":...}.\n\nFor the pre-existing ones, they have status \"accepted\" and no result/attempts. The worker will process them: set status completed, result \"processed:\"+payload, attempts 1.\n\nImportant: exactly once. The worker must not die mid-write or double-process. Since worker and api are separate processes but share the store dir, I need atomic writes and a worker lock to ensure single worker processing. Use a lock file (creat with O_EXCL or flock) around processing.\n\nLet me handle an in-flight marker: worker marks a job as \"processing\" (status) before completing, then writes completed atomically. On restart, any job left in \"processing\" should be retried (back to accepted or just reprocess). Since the operation result is derived from payload, it's idempotent — reprocessing is safe. To guarantee \"exactly once\" from the referee's perspective: final state completed, attempts=1, result=\"processed:\"+payload. As long as we record attempts=1 and don't duplicate, fine.\n\nNow the filename for opaque id: the id comes from path /jobs/. Opaque-id could contain arbitrary chars including '/'? Typically chunk is a single path segment. I'll URL-decode the segment and also sanitize for filesystem use, but must preserve exact id. To be fully robust and avoid path traversal, I'll map the id to a safe filename via a reversible encoding (e.g., base64 or percent-encoding), but store the real id inside the JSON. Then GET lookup translates id -> filename deterministically.\n\nSimplest robust: filename = urlsafe base64 of id + \".json\". base64url uses A-Za-z0-9-_ = safe for filenames. Store id inside. On lookups compute same encoding. But base64url can produce trailing '=' padding (the '=' char is problematic). Use urlsafe_b64encode without padding? Ambiguity minimal. Actually simpler: since ids here are simple, but to be robust use hashlib-based filename mapping with an index? That complicates. \n\nAlternative: store each job in a directory keyed by a sanitized version AND maintain an index file mapping hex(id->filename). But that adds complexity/crash risk.\n\nGiven ids are single path segments, I'll encode using a filesystem-safe reversible transformation: replace every character not in [A-Za-z0-9._-] with its percent-encoding using '_' as escape. This is reversible. For common ids (alphanumeric + dash) filename == id mostly, which is nice and debuggable. Let me implement:\n\ndef enc(s): return ''.join(c if re.match('[A-Za-z0-9._-]', c) else '_{:02x}'.format(ord(c)) for c in s)\ndef dec(s): ...\n\nThis is bijective for single segments (careful: '_' itself is safe char but also used as escape; need to escape '_' too? If id contains '_', ambiguity with escape. To be safe, also encode '_' as '5f'? Let me just not allow raw '_' — encode as '_c' no. Let me encode '_' as escape too. I'll define safe chars as [A-Za-z0-9.-] and anything else including '_' yields '_{2hex}'. And decoding: on '_', read next two hex. Since '.' '-' and alnum are safe and never start with '_', decoding is unambiguous as long as safe charset excludes '0-9a-f'? No — '_' followed by hex digits could be ambiguous with a literal underscore... but we never emit raw '_', always escaped. And '%'? not emitted. So decoding unambiguous. Good.\n\nNow, the storage dir permissions: /var/lib/accepted-jobs exists owned root. Good, we run as root.\n\nNow let me build:\n\nPython modules in /opt/jobserve/:\n- store.py: functions for job path, read, write (atomic), list.\n- server.py: http server on 8080.\n- worker.py: polls queue.\n\nStart scripts:\n/etc/replaybook/job-api-start:\n```\n#!/bin/sh\nexec /usr/bin/python3 /opt/jobserve/server.py\n```\nWait — the unit ExecStart is `/bin/sh /etc/replaybook/job-api-start`. And `ConditionPathExists=/etc/replaybook/job-api-start`. So the script must exist. Provide .sh executable script.\n\nThe unit sets Restart=always RestartSec=1, so if server exits it restarts. Good.\n\nNow, need to consider: job-api.service has After=accepted-job-spool and Requires. And ConditionPathExists. Fine.\n\nLet me check if services are currently enabled in systemd and their state. Also check whether systemd already knows these units. They're in /etc/systemd/system as symlinks (unit-... from /nix/store). For them to be active, they must be enabled (symlinked into /etc/systemd/system or a *.wants? Actually files present in /etc/systemd/system are loaded by name regardless of enable? Unit enable sets WantedBy symlinks in /run/systemd /... Let me check status.\n\nLet me just check `systemctl status job-api job-worker accepted-job-spool`.\n\nI'll proceed to check re-playbook dir exists (it does, empty). I need to enable the units. Let me check.\n\nLet me also verify python3 absolute path and that we can bind port 8080.\n\nLet me now set up the code.

I\n'll use\n it.\n\nNow\n let me write the Python code.\n I'll place\n it in /var/lib/job-worker\n/ \nas the durable code home,\n plus\n start\n scripts in /\netc/replaybook.\n\nLet me write:\n\n1. /var/lib/job-worker/store.py - shared storage helpers.\n2. /var/lib/job-worker/server.py - HTTP server.\n3. /var/lib/job-worker/worker.py - worker.\n\nStorage dir: /var/lib/job-worker/jobs/\n\nLet me define the store.\n\n```python\nimport os, json, re, base64, tempfile, time\n\nJOBS_DIR = os.environ.get(\"JOBS_DIR\", \"/var/lib/job-worker/jobs\")\n\ndef init():\n os.makedirs(JOBS_DIR, exist_ok=True)\n\ndef encode_id(jid):\n # filesystem-safe reversible encoding\n out=[]\n for c in jid:\n if re.match(r'[A-Za-z0-9.-]', c):\n out.append(c)\n else:\n out.append('_'+c.encode('utf-8').hex())\n return out\n\n```\n\nWait, repeating ord per char — for non-ascii, use utf-8 hex bytes. To decode, I need unambiguous parse. Let me implement encode using percent-style but reversible:\n\nsafe chars: alnum, '.', '-'. For unsafe char, output '=' + hex(codepoint). But '=' is in safe filename? '=' is not in my safe set, so a literal '=' in id becomes '=3d'. Then decoding unambiguous: when we see '=' read until next hex value length? Need fixed width. Use '=xx' where xx hex of byte, but multi-byte for non-ascii. For simplicity use codepoint hex of char with 4 hex digits: '=XXXX'. Fixed width 4. Safe.\n\n```python\n_S = \"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-\"\ndef encode_id(jid):\n out=[]\n for c in jid:\n if c in _SAFE and not (c ... ) ...\n```\n\nCareful: decode sees '=' then 4 hex chars. But a literal char in id could be '=' (escaped) or could a safe char be followed... The sequence '=XXXX' only produced by escape. Since safe chars never produce '=', and any actual '=' is escaped, ambiguity: could an id contain literal chars that when concatenated look like '=XXXX'? Only if id literally contains 'X' after '='... but '=' is always escaped so a raw '=' never appears. So no ambiguity. Good.\n\nActually also need to make sure safe charset excludes '.'?? '.' is fine in filenames. But could produce ambiguity? No, '.' not used in escape. Fine. Keep '.' and '-' safe, exclude '_' to avoid confusion. Use '=' escape.\n\nLet me finalize encode:\n```python\ndef encode_id(jid):\n esc=[]\n for ch in jid:\n if ch in _SAFE:\n esc.append(ch)\n else:\n esc.append('=' + format(ord(ch), '04x'))\n return ''.join(esc)\n\ndef decode_name(fn):\n # reverse\n if fn.endswith('.json'):\n fn = fn[:-5]\n out=[]\n i=0\n while i < len(fn):\n c = fn[i]\n if c == '=':\n hexv = fn[i+1:i+5]\n out.append(chr(int(hexv,16)))\n i += 5\n else:\n out.append(c)\n i += 1\n return ''.join(out)\n```\n\nBut note: file may not end with .json if id itself ends with .json? We append '.json' to the encoded name. So filename = encode_id(id) + '.json'. decode strips trailing '.json' then decodes. But what if encoded id ends such that id already ends with '.json'? e.g. id=\"x.json\" -> encode -> \"x.json\" + \".json\" = \"x.json.json\". decode: strip '.json' -> \"x.json\", decode -> \"x.json\". Correct because filesystem name distinguish. Good.\n\nJob path:\n```python\ndef job_path(jid): return os.path.join(JOBS_DIR, encode_id(jid) + '.json')\n```\n\nread_job(jid): if exists return dict else None.\nwrite_job(jid, rec): atomic write: tmp in JOBS_DIR, fsync, rename.\nlist jobs: iterate dir files, decode id, read.\n\nNow server.py using http.server ThreadingHTTPServer with handler.\n\nRoutes:\n- GET /health -> 200 \"ready\"\n- any /jobs/... with POST method: id = rest path. Read body bytes (raw) = payload. Create job status accepted, attempts 0. Respond 202.\n- GET /jobs/ -> lookup, return json.\n\nBut note: the pre-existing accepted jobs have no attempts/result fields. Upon import... My server reads the file as-is. After worker processes, it gets attempts=1, completed result. Good.\n\nBut GET on an accepted-but-not-yet-processed job returns status accepted, result null, attempts 0. That's fine.\n\nAlso the worker might not have processed them yet when referee GETs. I need to ensure the worker processes quickly and the jobs end completed. The referee presumably polls. I'll make worker process immediately on startup and repeatedly.\n\nEdge: POST /jobs/ where could include URL encoding. I'll unquote the path segment.\n\nLet me handle path parsing robustly: self.path like '/jobs/accepted-alpha-7d3'. Split. Use urllib.parse.\n\nNow duplicate jobs: If POST for an id that exists as completed, should we reset? The contract says \"accepts the raw request body as the job payload\". I'll overwrite/create: if job exists, replace payload and reset to accepted attempts 0. That matches \"accept\". Fine.\n\nReturn 202 with empty body (or maybe echo). 202 Accepted. I'll return empty.\n\nNow worker.py:\n- acquire lock (single instance)\n- loop:\n - list jobs with status 'accepted' OR 'processing' (stale)\n - for each: mark processing (persist, attempts stays 0? attempt count?) then complete: status completed, result 'processed:'+payload, attempts 1. Atomic write.\n - sleep briefly, repeat.\n\nSince we persist 'processing' before completing, if crash between, on restart we retry processing jobs. Good. \"Exactly once\": final state unique, attempts=1.\n\nBut \"attempts\" semantics: Contract says completed => attempts == 1. During processing maybe set attempts 1 already. It only specifies completed state. I'll set attempts=1 at completion.\n\nWorker lock: use flock on a lock file to prevent two workers. Use `fcntl.flock` with LOCK_EX | LOCK_NB; if fail, exit (another worker running).\n\nNow to guarantee \"exactly once\" processing & not reprocessing completed, we only consider accepted/processing states.\n\nLet me write files now.\n\nAlso need to make sure POST creates job in store even if that id was one of the pre-existing accepted ones. Pre-existing ones are in /var/lib/accepted-jobs. My server reads from /var/lib/job-worker/jobs/. These are different dirs! The pre-existing accepted jobs must be recovered into MY store. So my server/worker must import from /var/lib/accepted-jobs into /var/lib/job-worker/jobs.\n\nI'll have the worker (or server) at startup import any files from /var/lib/accepted-jobs that aren't already in my store. Import once: copy the record (id,payload,status=accepted, result null, attempts 0). Then worker processes them.\n\nBut \"recover and process exactly once. Do not discard it, replace it, or invent substitute identifiers.\" Importing copies the record with the same id and payload - that's preserving. Then complete. The original file in /var/lib/accepted-jobs can remain untouched (don't delete). Good.\n\nLet me make the worker handle import too, or a dedicated routine in server startup. I'll do import in server startup AND worker startup (idempotent: only import if not existing in my store). Actually better to do it in a shared init. Let me have both call `import_accepted()` at start.\n\nLet me write it all.\n\nPath for python store: put code at /var/lib/job-worker/{store,server,worker}.py and start scripts at /etc/replaybook/job-api-start and job-worker-start.\n\nLet me now also confirm: the systemd unit ExecStart is `/bin/sh /etc/replaybook/job-api-start`.

You have root access and 900 seconds.\n\nExpose HTTP on port `8080` with this public contract:\n\n- `GET /health` returns HTTP 200 with the exact body `ready`.\n- `POST /jobs/` accepts the raw request body as the job payload and returns HTTP 202.\n- `GET /jobs/` returns JSON containing `id`, `payload`, `status`, `result`, and `attempts`.\n- Completed jobs have `status` equal to `completed`, `result` equal to `processed:` followed by the original payload, and `attempts` equal to `1`.\n\nOpaque work accepted before you arrived is present somewhere on the host. Recover and process it exactly once. Do not discard it, replace it, or invent substitute identifiers.\n\nThe worker lifecycle must be exposed as `job-worker.service` so operations can restart it independently. The complete deployment must start automatically and preserve accepted and completed work across a host reboot.\n\nChoose the implementation, storage, process topology, and tooling yourself. Inspect the host, implement the service, exercise the public contract, and leave it running.\n\n\nThe controller-owned referee is the only authority on completion. Implement and verify the requested outcome on this host, then leave it running. Referee evidence, hidden topology, other competitors, and future events are not available to you.
