      an OCR run starved the server of threads to answer on (v0.3.102) · f4426b19
      Stefy Lanza (nextime / spora ) authored
      The admin RunPod page showed:
      
          error: Unexpected token '<', "<!doctype "... is not valid JSON
      
      That '<' is nginx's HTML error page. The page was not failing to find data; its
      fetch never got an answer, the proxy gave up, and JSON.parse was handed HTML.
      Measured from inside the host, mid-run, with 64 pages in flight:
      
          /healthz            200 in 0.002s     no thread needed
          /v1/models          200 in 0.006s     no thread needed
          /metrics            200 in 0.18s      no thread needed
          /v1/runpod/status   no answer in 30s  needs a thread
      
      `asyncio.to_thread` hands work to the loop's default executor, and a loop that
      was never told otherwise builds one with min(32, cpu_count + 4) — 20 threads on
      a 16-core host. Nothing in this codebase ever called set_default_executor. That
      number is for incidental background work measured in milliseconds; what we put
      on it is `pool.acquire()` waiting out a pod boot (MINUTES) and a per-page OCR
      forward (30-300s each), `ocr.max_concurrency` of them at once. The log says it
      plainly: "engine 'surya': 8 instance(s) ready, 8 lane(s) each — 64 pages at
      once". 64 blocking calls, 20 threads. Everything else waits behind a page.
      
      Nothing was broken. The server could not get a thread to answer on.
      
      codai/api/thread_pool.py now sizes two pools from the concurrency the install
      is CONFIGURED for rather than from its CPU count — these threads wait on other
      machines, so what matters is how many remote calls may be outstanding, not how
      many cores can run Python:
      
        * the DEFAULT executor, floor 32, for everything to_thread is used for today;
        * a separate POD executor, floor 64, for the calls that block for minutes, so
          that however many pages are in flight a control-plane request still finds a
          free thread.
      
      Both entry points install it (the front blocks on pool.acquire for whole pod
      boots, so it needs this at least as much as the engine). The pod pool copies
      the context the way to_thread does — the per-page options and the token trace
      are ContextVars, and run_in_executor does not copy by itself; a page losing its
      budget because it changed pools would be a nasty way to learn that.
      
      /v1/runpod/spend also took its snapshot ON the loop: pods_status() takes the
      pool locks and the ledger reads a file, so a lock held by a provisioning thread
      stalled every request rather than one. It runs in a thread now.
      
      A thread waiting on a socket costs a stack and nothing else. The asymmetry is
      the point: too small costs availability, too large costs memory we have.
      
      Also fixes a test of my own from an hour ago that asserted "tomorrow 02:00" is
      within 24 hours and went red at 00:22. The test was wrong about the clock, not
      the code about the booking.
      
      15 tests, including the live failure reproduced: fill the pod pool and check
      the control plane still answers. Suite: 3166 passed, the same 13 known-stale
      failures.

      ten connections is a browser's number, not a fan-out's (v0.3.101) · a90b93a2
      Stefy Lanza (nextime / spora ) authored
      One shared session serves every pod, and `requests`' stock adapter keeps ten
      connections per host. `ocr.max_concurrency` defaults to 64 and is 128 on the
      install this came from, so from the ELEVENTH concurrent page onward urllib3
      opened a connection, used it, found the pool full on release and threw it
      away:
      
          urllib3.connectionpool: Connection pool is full, discarding connection:
          194.68.245.54. Connection pool size: 10
      
      74 of those in five minutes — about fourteen a minute against one pod — while
      that run's health checks were timing out. Every discarded connection means the
      next page pays a full TLS handshake to a machine in another country: several
      round trips of latency each, and handshake CPU on the orchestrator at precisely
      the moment it is busiest. It does not CAUSE a slow run, but it multiplies one,
      and it is the part that is ours.
      
      The pool is now sized from the concurrency the install is configured for:
      `ocr.max_concurrency`, floored at 64 and capped at 256. Read at session
      creation rather than at import, because the config is not loaded when this
      module is imported — and because an operator raising max_concurrency should not
      have to know a connection pool exists. An idle connection costs a socket and
      nothing else, which is the cheap side of this trade.
      
      The adapter also carries the floor as its own default, so a `_PinnedAdapter`
      built anywhere cannot silently fall back to ten.
      
      Routing is deliberately unchanged: only https-to-a-bare-IP uses the pinned
      session, everything else still goes through `requests` untouched, so callers
      and tests that patch `requests.get` keep working.
      
      Not a fix for the slowness that exposed it. That host was running MariaDB at
      534% CPU, four Postgres parallel workers, and a backup that had been streaming
      over SFTP for three hours, against coderai's own 8.8% of one core out of
      sixteen — the orchestrator was waiting for a CPU, not using one.
      
      9 tests. Suite: 3151 passed, the same 13 known-stale failures.

      the growth line named a trigger that had not fired (v0.3.100) · 24911c74
      Stefy Lanza (nextime / spora ) authored
      A pool with one healthy pod rented a second one second after the first became
      ready, and said:
      
          'datalab-to/surya-ocr-2': growing to meet 1 pod(s) of demand — 1 up, 1 booting
      
      It needs one pod. It has one pod. It is renting another. Read plainly that is a
      double-rent bug, and it took a real investigation to establish that the fleet
      was behaving exactly as configured.
      
      `_should_grow` has two independent triggers:
      
        DEMAND       (in-flight + waiting) / scale_up_inflight_per_pod, rounded up —
                     a measured number, and the one that may rent several at once.
        SATURATION   every serving pod is at its in-flight threshold, so the NEXT
                     request has nowhere good to go. Anticipatory, single-flight.
      
      What happened was saturation: 16 pages landed on the one pod the moment it went
      ready, 16 at a threshold of 16 is exactly one pod's worth, so demand was already
      MET and that branch did not fire at all. But the caller computed
      `_pods_for_demand()` itself, after the fact, and printed it whichever branch had
      answered — so the line always claimed demand, and in the saturation case
      reported a number that contradicted the action it was describing.
      
      The decision now carries its own reason. `_grow_reason()` returns the sentence
      of the trigger that fired ('' for no), `_should_grow` is `bool()` of it — the
      bool contract is unchanged, callers and tests compare with `is True` — and
      acquire() prints what it was given instead of recomputing a figure of its own.
      Saturation now says so, and says what it is NOT:
      
          growing — every pod is at its 16-in-flight threshold (least loaded carries
          16) — renting one more for the next burst, not for work already queued
          [1 up, 1 booting]
      
      Nothing about when a pod is rented changes; only what the log says about why.
      
      10 tests, including the live line as a regression: a saturation rent must not
      contain the word "demand". Suite: 3142 passed, the same 13 known-stale failures.

      an API that cannot be asked is not a pod that failed (v0.3.99) · e86dc161
      Stefy Lanza (nextime / spora ) authored
      A request for an embedding model rented a pod, which began pulling a 9.65 GB
      image that had been pushed twenty minutes earlier — a five-minute cold pull, and
      the ORDINARY case for the first pod on a newly tagged image. Two minutes in,
      RunPod's control plane answered HTTP 503 once. Three defects then fired in
      sequence, and the pod that was coming up fine became an untracked GPU billing at
      $1.09/hr:
      
        21:36:58  pod created — booting
        21:38:00  still no port after 62s (status=RUNNING) — image pull in progress
        21:38:50  boot FAILED: RunPod API HTTP 503: Service Unavailable
        21:38:53  POST /v1/embeddings  502
      
      1. THE BOOT WAIT CONDEMNED THE POD FOR THE API'S FAILURE. Any exception out of
         the wait is read as "this pod failed to boot", and `get_pod` raised straight
         through the poll loop. A 503 from the control plane means the question went
         unanswered; it says nothing about the machine. RunpodTransient (a subclass,
         so every existing `except RunpodError` is unchanged) now marks 5xx/408/425/429
         and transport errors, and the wait keeps polling to the deadline the caller
         set, saying once that the API is quiet and again when it comes back. A wait
         that never got a single answer raises transient too — "unknown, not
         known-bad" — rather than handing the teardown path a verdict nobody reached.
         401 and 4xx stay final: those will say the same thing in five seconds.
      
      2. THE TEARDOWN RAN THROUGH THE SAME DEAD API, INSIDE `except Exception: pass`.
         The attempt most likely to fail is the one that matters most, and its failure
         was dropped on the floor — no log line anywhere named the pod. terminate_pod
         now retries with backoff while the error is transient, and the boot handler
         prints what is still billing, at what rate, and how to stop it. A pod that
         could not be terminated KEEPS its registry entry: that entry is the only
         record it exists. `_give_back` had the mirror image of the bug — it
         unregistered unconditionally, throwing away the record of a live pod — and
         now forgets only what is actually gone. A boot that failed also ledgers the
         minutes it burned; no pool ever held that pod, so nothing else would.
      
      3. THE REAPER COULD NEVER HAVE CLEANED UP AFTER EITHER. Pod age came from
         `runtime.uptimeInSeconds`, which is the CURRENT RUN's uptime and resets on
         every container restart. The leaked pod reported 234s while it was 11 minutes
         old, and its uptime reset every few minutes, so it could never cross the
         1200s grace — the pod that most needs reaping, one nothing tracks that is
         failing over and over, was the one pod the reaper was structurally blind to.
         `lastStatusChange` carries the rental time ("Rented by User: Thu Oct 15 2026
         19:36:58 GMT+0000") and was already in the response; list_pods now asks for
         it. Age is the larger of rental age and uptime — uptime cannot exceed the
         age, so the pair is still a true lower bound, and a pod whose stamp will not
         parse is no worse off than before. A future stamp is refused rather than
         making every pod ancient, and no age at all is still None: the reaper fails
         closed on that.
      
      Found because the image update was the trigger: a new tag is cold in every
      datacenter, so the first boot after every release spends minutes exposed to
      exactly this. The next pod proved the image itself was fine — 301s of pull, 22s
      of warm-up, 200 OK.
      
      27 tests. Suite: 3132 passed, the same 13 known-stale failures.

      autoupgrade: asking for the upgrade NOW was an undocumented file edit · 9ba04161
      Stefy Lanza (nextime / spora ) authored
      The unattended policy has two states: wait for an idle moment, and — on a host
      that is never idle — book a forced upgrade for the next midnight. Neither is an
      operator saying "take it now". There was no way to say that at all. The only
      lever was the booking file:
      
          echo 1 > ~/.local/state/coderai/force-upgrade-at
      
      which works by accident (epoch 1 is in the past, so the next tick fires), is
      written nowhere, and is NOT self-clearing when the run finds nothing to upgrade.
      Observed on a production orchestrator: a `1` left from one forced release turned
      every hourly tick for the next day into "a FORCED upgrade is booked", silently
      disarming the idle check that protects live requests. Nobody asked for that; it
      was the residue of a one-off.
      
      So the three things an operator actually wants are options now:
      
        --force          upgrade and restart on THIS run, idle or not, and leave no
                         booking behind. It sets FORCED before the upgrade block, so
                         it also lands an upgrade already sitting in the image behind
                         deferrals — that host is precisely who types this.
        --force-at WHEN  book one (anything date -d takes). No second timer: the
                         hourly tick at or after WHEN takes it.
        --cancel-force   drop a booking, whether an operator made it or the script
                         armed it after MAX_DEFERRALS busy ticks. The arming message
                         now names this instead of telling you to delete a file.
      
      The two booking edits return before the runner check and before anything touches
      a container engine, so they work on a host where the upgrade itself could not
      run, and they are written to the same log as the runs they change — a schedule
      change belongs in the history of the schedule.
      
      --help exists, and an unknown option is a usage error rather than a silent
      unattended run under a typo.
      
      Also drops one install's name from a sentence in the guide that did not need it.
      
      13 tests. Suite: 3105 passed, the same 13 known-stale failures.

      twelve red tests were wrong about the code, not the other way round · bd698488
      Stefy Lanza (nextime / spora ) authored
      The suite has carried 25 failures for long enough that a real regression could
      hide in them — which is the failure mode that cost a full day this week. Twelve
      are fixed here. Every one was a test pinning behaviour that had been
      deliberately changed; no product bug was found.
      
      Two were actively harmful rather than merely stale:
      
        * test_build_hardware_summary faked `torch` and asserted 10240 MB of free
          VRAM. The summary moved off torch.cuda.mem_get_info on purpose — that path
          pinned a ~256 MiB CUDA context just to answer a hardware question — so the
          fake went unused and the test measured the REAL card of whatever machine
          ran it. It read 24111 here. A test that depends on the host's GPU is not a
          test; it now patches visible_gpu_memory(), which is what the code calls.
      
        * test_main_wiring_falls_back drove the whole of main() through a wall of
          stubs to reach one line, so every new config field or call surfaced as an
          AttributeError raised from INSIDE the code under test. Three of them, each
          reading exactly like a product bug. It now asserts the thing it exists
          for — an invalid broker config yields a disabled runtime rather than
          stopping the server — directly.
      
      The rest, by cause:
      
        * the broker protocol's accept field is `status: "ok"`. Six fixtures sent
          `accepted: true`, a field that appears nowhere in the client, which sends
          {"event":"pending","status":"pending"} itself and documents the server's
          heartbeat reply as status=ok. Registration now succeeds in the fakes.
        * `v1/…` endpoint lists were frozen copies that broke every time the product
          gained a route (eight by the time anyone looked) while saying nothing
          about whether the advertised routes exist. The studio-endpoints test now
          checks them against the app's real routes — the contract its name always
          claimed — comparing route SHAPES, since parameter names are local detail.
        * whisper: posting an existing id is an EDIT. The handler says so where it
          does it ("Otherwise editing an existing whisper-server model would either
          409 or silently create a duplicate config"); the test demanded the 409
          that comment describes removing.
        * whisper runtime fake: `is_running` always answered True and then expected
          start() to be called, and it defined `cleanup` but not `stop` — the unload
          path calls stop(), so it raised into an `except Exception: pass` and the
          server looked un-stopped with nothing saying why.
        * calling a FastAPI handler as a function leaves unpassed parameters as
          Form(...) sentinels: "unsupported operand type(s) for +: 'Form' and
          'Form'". That test drives the real route now.
        * there is no GET /admin/api/settings any more, and the LongCat image builds
          its 3.10 venv in a python:3.10-slim stage rather than with a literal
          `python3.10 -m venv`.
      
      One real inconsistency surfaced on the way: the broker is advertised
      `v1/video/compose/{id}` where the app serves `{job_id}`. Shape-compatible, so
      nothing breaks; the advertised list is simply inaccurate. Not changed here,
      because what we advertise is a wire-visible contract.
      
      13 remain: the broker handshake tests encode server-greets-first against a
      client that says "Client speaks first", plus streaming and studio shapes.

      surya read nothing because its lease never stayed home (v0.3.98) · 279df06b
      Stefy Lanza (nextime / spora ) authored
      THE SURYA BUG. `/v1/ocr/attach/<lease>/…` is an OCR engine attaching to THIS
      install's gateway. The lease is minted here and lives in this process's memory
      — and the remote gateway was FORWARDING those requests to the pod, which
      correctly refused a token it never issued:
      
          404 {"error": {"message": "unknown OCR engine lease"}}
      
      surya's client swallows that and returns an empty generation, so every page
      came back unread with the GPU never asked to read one. Measured on a clean
      2-page PDF that chandra (2212 chars) and olmOCR (1992) both read: surya
      returned 2 characters, and the pod's vLLM logged a single 6-token warm-up for
      the whole document. $88 of surya time in one day produced nothing.
      
      The gateway behind that prefix does its OWN forwarding, with its own pool and
      its own lease. That is the hop, and it has to start here. `/v1/ocr` itself
      stays routable, so pinning the attachment does not strand the subsystem.
      
      This also corrects an earlier diagnosis of mine: v0.3.87 treated this as a
      lease VOIDED BY A RESTART and shipped a re-resolve for it. No restart was
      involved — the lease was wrong from the first page, which is why surya has
      been broken continuously rather than only after restarts. That work was not
      wasted (the retry cap took four paid generations per page down to two, and the
      502 plus `unread_pages` are what made this diagnosable at all) but it did not
      address the cause.
      
      Third instance today of one mistake: the gateway forwards anything under /v1/
      that looks like a model request, including this install's own control plane.
      /v1/runpod rented a pod to deliver a teardown; /v1/loras was staying local by
      luck; now the OCR lease. All three are pinned. The structural answer — making
      control-plane routes opt IN to forwarding — is not in this commit.
      
      Also in here, from the fleet-hygiene pass:
      
        * accelerate added to every profile that carries transformers (audio, ocr,
          stt, tts, voice, tts-xtts.venv-TTS), with a test that fails if a new
          profile reintroduces the gap. Same latent fault that broke embeddings.
        * an embeddings pod is warmed on /v1/embeddings, not with a chat completion
          it refuses by design — that 404 was printed on every boot of a healthy pod
          and cost a wrong diagnosis.
        * the seed plan is announced once, not every fifteen seconds while a pod
          boots, so a boot log stays readable when it matters.
        * `pool:` is dropped from pod NAMES (ownership is the prefix, never the rest).
        * the reaper owns a pod by REGISTRY as well as by name, so renaming
          deployment_id no longer orphans pods that are already running and billing.

      a pool sibling reached the pod with no engine (v0.3.97) · ad2057da
      Stefy Lanza (nextime / spora ) authored
      Reported from production, minutes after v0.3.96 made an adapter a model of its
      own on the pod:
      
          503 Model 'diogene-alpha' failed to load: Unknown backend: cpu
      
      Only the pool's OWN entry was seeded with its engine. Siblings got none, so the
      adapter arrived on the pod with no backend and fell through to the pod's
      default. Verified against the live catalogue: the seed genuinely had no
      `backend` key.
      
      This had always been wrong and could not bite before, because an adapter
      collapsed into its base on the pod and was never a model of its own to LOAD.
      Making it one — which was the right fix — is what exposed it.
      
      Every sibling now takes the POOL's engine, not its own. A pool is one pod
      running one image, so siblings cannot each have a different engine: seeding
      one would describe something the pod cannot satisfy, and the failure would
      land minutes later inside a rented machine. A test asserting the opposite was
      written and then corrected.

      an adapter is named for what it does, not for what it is (v0.3.96) · e679b21d
      Stefy Lanza (nextime / spora ) authored
      Five fixes, two of them reported from production in the same hour.
      
      EMPTY REPLIES from a chat naming `diogene-alpha`, while `qwen38` — the same
      weights on the same pod — answered normally. Parser selection reads the model
      NAME:
      
          if 'qwen' in model_lower:  -> QwenParser
      
      `qwen38-awq` matches; `diogene-alpha` matches nothing and fell to the generic
      parser, so the model's <think>…</think> block was never separated from the
      answer. With a modest max_tokens the whole budget goes into reasoning that
      never closes, and the caller sees an empty reply from a 200 — the hardest kind
      of wrong to see. A LoRA is named for what it was trained to do; it is the same
      FAMILY as the weights it adapts, so a name matching nothing now resolves to the
      base's. Nothing is discarded: the thinking comes back as `reasoning` and
      `reasoning_content`, as it always did for the base.
      
      This also corrects a reading of my own: every temperature-0 comparison in this
      chain showed the adapter leaking its reasoning while the base answered cleanly,
      and I took that as evidence the adapter was not loading. It was the parser.
      
      /v1/chunk with X-Coderai-Placement: remote answered 502 "nothing configures
      'embeddings' to run remotely" while a coderai-embeddings pod — which has the
      chunker in it — sat there serving bge-m3. A capability-only request names no
      model, so the per-model placement that moved everything else cannot place it.
      It now borrows the destination of a model OF THE SAME CAPABILITY that is
      already remote. Same capability only (an embeddings pod has no OCR deps), and
      only on an explicit `remote`: nothing should rent a GPU to run a regex split
      because nobody said otherwise.
      
      Registering an adapter is not serving it. vLLM takes its adapters at launch and
      the code that adds one to a live engine sits on the model-LOAD path, which does
      not run again for a model this instance already loaded. So a pod could be sent
      an adapter, register it, report it in /v1/loras and go on answering from the
      base. Registration now hands it to the running engine, swapping a stale one.
      
      A stale content id repairs itself. v0.3.94 fixed what new uploads are stored
      as; an entry already registered under a non-canonical id stayed broken with no
      symptom but base-model answers. Seeding and pushing resolve an id against the
      CONTENT first.
      
      And `it-legal` now sets min_chunk_chars: 300 (strict stays 0) — it is the
      OCR-aware template, so it meets short trailing sections more often, and a
      56-character chunk is too small to carry meaning and long enough to match. A
      runt folds only into a chunk that can CARRY it, so a document of short sections
      stays several chunks instead of collapsing. Absorption may never cross
      conclusioni <-> dispositivo at any size: what a party asked for and what the
      court decided, and a recorded label is a weaker guarantee than refusing the
      merge.
      
      NOTE: this release MOVES CHUNK BOUNDARIES for anyone using `it-legal`.

      a chunk template name meant something else on the far side (v0.3.95) · a908cedd
      Stefy Lanza (nextime / spora ) authored
      /v1/chunk already rode the embeddings capability, so it could be placed here,
      on a RunPod pod (the coderai-embeddings image) or on a cluster node. Verified
      end to end for the first time rather than inferred from the routing table: a
      capability image really serves the route, and the middleware really forwards it
      ("[remote-gateway] /v1/chunk -> … (capability 'embeddings')").
      
      That testing found a real defect. A NAMED structure template was forwarded as a
      bare name whenever the name was a BUILT-IN, on the reasoning that every coderai
      has those. True of the name; not true of what it means. `it-legal` was widened
      to accept markdown headings in 0.3.87 and `it-legal-strict` did not exist
      before it — so a pod on an older image resolves the same name to different
      anchors, or 404s on one it has never heard of. A pod fleet is mixed-version by
      nature: one rented an hour ago runs whatever `:latest` meant then.
      
      Chunk boundaries that differ by which machine answered make a retrieval index
      unmeasurable, which is the one thing docs/chunking.md exists to prevent. Every
      named template is inlined now, built-ins included: a few hundred bytes on the
      request, and the boundaries become a property of THIS install's version.
      
      An unknown name is still forwarded untouched — resolution failing here must not
      swallow the request, and the remote's `unknown_template` is a clear error.
      
      Six tests pin the placement itself: local by default (a regex split must not
      rent a GPU), forwarded to a node, left here when only another capability is
      remote, the template inlined on the wire, and one request pinned local by
      header. Plus the note that a per-model remote does NOT move chunking, because a
      chunk request carries no model and only the capability map places it.

      an adapter id named the container, not the content (v0.3.94) · 11569dd5
      Stefy Lanza (nextime / spora ) authored
      The root cause under four releases of "the adapter is not applied". Measured on
      a live pod:
      
          catalogue says       : sha256:b8eac366…   (hash of the tar a client sent)
          this bundler's own   : sha256:2e820c…     (same content, its own packing)
          pod lookup b8eac366  : 404
          pod upload returns   : {"id":"sha256:2e820c…","existed":true}
      
      `save_lora_blob` stored an uploaded bundle under the hash of THE BYTES THAT
      ARRIVED. A tar of one adapter made by GNU tar, by this bundler, or by anything
      else hashes differently — mtimes, ownership, member order — so the id recorded
      in the catalogue was one nobody else could reproduce. Every later push
      re-bundled the unpacked directory, stored the canonical id, and the pod looked
      up the uploaded one and found nothing. It had the bytes the whole time, under
      another name, so it loaded the base model and answered under the adapter's
      name. Fluently, with nothing in the reply to say so.
      
      An uploaded bundle is now unpacked FIRST and stored under the id of this
      bundler's packing of it, which is what every side computes. /v1/loras/upload
      returns that id, so what a client registers is what a pod can resolve.
      
      This is also why it took four attempts: the engine flags, the seeding and the
      entry propagation were each genuinely broken and each fix was real, but
      underneath them the two sides were never going to agree on the id.
      
      _load_lora_runtime had two bare `return False` paths — no adapter spec, or an
      id the blob store cannot resolve — which is exactly why this hid for three
      releases while every other layer was examined. Both say what happened now, and
      the second says the thing that matters: the catalogue and the store disagree
      about this adapter's id.

      the bytes reached the pod, the entry did not (v0.3.93) · 123fe538
      Stefy Lanza (nextime / spora ) authored
      Measured on a live pod. The pool gate from v0.3.91 worked —
      
          [lora] no adapters yet, but this engine serves a pool — starting with LoRA
                 enabled so one can be added without a reload
          [vllm] launching: … --enable-lora --max-lora…
      
      — and the adapter was still dropped:
      
          pod seeded expecting : sha256:2e820c…     (the local adapter directory)
          re-registered as     : sha256:b8eac366…   (an uploaded blob)
          orchestrator pushed  : b8eac366… ✓ 159 MB
      
      The bytes arrived. The pod's CATALOGUE did not. It was seeded at boot with the
      first id, /v1/loras/register repointed the entry at the second, and nothing
      told the pod — so its engine looked for an id nobody holds, dropped the
      adapter, and served the base under its name. (The bundle hash is deterministic;
      the two ids differ because the adapter genuinely changed, not because hashing
      is unstable.)
      
      Two keys missing a version, the same shape as every other bug in this area:
      
        * _ensure_adapters sent the BYTES only. It sends bytes and entry now.
        * teach_model keyed "already taught" on (pod, model), so a re-register could
          never reach a pod it had spoken to once. Keyed on the adapter's source.
      
      /v1/loras listed only the TRAINING registry, so an adapter that arrived by
      upload+register was invisible there — a successful registration looked exactly
      like a failed one, which is how this was found. It lists both now, tagged
      `trained` or `registered`, with the adapter id, base and pool.

      vLLM was never launched able to accept tool calls (v0.3.92) · 7601bdf9
      Stefy Lanza (nextime / spora ) authored
      Reported from production:
      
          500 {"detail": "Generation error: the pod answered 500: Generation error:
               400 Bad Request … \"auto\" tool choice requires
               --enable-auto-tool-choice and --tool-call-parser to be set"}
      
      Not a regression: `tools` has never worked on a vLLM-backed model here. The
      proxy forwards them correctly — the remote decides what it supports — and
      nothing ever launched vLLM able to take them. A request-time 400 from a server
      that started cleanly, for a capability the catalogue advertises, naming two
      flags the caller has no way to set.
      
      A tool call is TEXT the model emits in its own trained format, so the parser
      belongs to the model FAMILY rather than to the deployment, which is what makes
      a default possible at all. `tool_call_parser` defaults to "auto" and picks from
      the model name (qwen->hermes, llama-3->llama3_json, mistral, deepseek_v3,
      glm45, qwen3_coder…), longest match first so qwen3-coder is not swallowed by
      qwen. An explicit value wins, per install or per model in its `vllm` block —
      and that block now travels to a pod, so a pod serves a model the way this
      install does.
      
      "off" is honoured rather than overridden: a family guessed wrongly does not
      fail, it parses tool calls into nonsense, and silently producing wrong tool
      ARGUMENTS is worse than refusing the request.
      
      Both flags go together or neither: vLLM refuses to START with
      --enable-auto-tool-choice and no parser, and an engine that will not boot is
      worse than one that cannot do tool calls. An unrecognised family logs which
      setting to use, because otherwise the symptom lands on the client as a 400.

      a retrain keeps the name and changes the bytes (v0.3.91) · 6ac424e9
      Stefy Lanza (nextime / spora ) authored
      Re-registering an adapter updated the catalogue and the pod went on serving the
      OLD weights. Two caches, neither of which had a version in its key:
      
        * the orchestrator remembered "this pod already has this adapter" by NAME, so
          the new bytes were never sent;
        * and the engine was asked "do you serve this name?" — which a stale adapter
          answers yes to. It kept what it was launched with.
      
      So the update looked applied from every angle a client can see: the catalogue
      had the new blob, the name worked, the request succeeded. The only symptom was
      output identical to the previous version, which is exactly the symptom nobody
      can see from a 200.
      
      Both are keyed on the adapter's SOURCE now. When it changes, the bytes are
      pushed, the old adapter is unloaded from the running engine and the new one
      takes its name — no reload of the base model, nothing else on the pod
      disturbed. When the swap cannot be done in place the engine is restarted with
      the new adapter, and says which it is doing.
      
      An engine coderai holds no record for is never treated as stale: unloading an
      adapter on a guess is worse than serving the one that is there.
      
      Content-addressed versioning is what makes this safe to run on every retrain —
      bytes that have not changed are recognised as the same adapter and nothing
      reloads.

      an uploaded adapter can now become a served name (v0.3.90) · bd96f81e
      Stefy Lanza (nextime / spora ) authored
      /v1/loras/upload put the bytes somewhere; nothing made them answerable. The
      last step was editing models.json by hand, which is not a step a team
      retraining adapters can automate — so the answer to "how do we send you a
      QLoRA?" was "send it to us and we will register it", with a human in it.
      
      POST /v1/loras/register {name, base, adapter} closes that. It joins the BASE'S
      POOL by default, which is the entire economy of the thing: the base weights are
      already loaded on a rented card, an adapter is tens of megabytes of deltas, and
      vLLM applies them per request. It inherits the base's placement, card choice
      and budgets, and deliberately does NOT inherit min_pods or keep_warm — an
      adapter rides the base's pod, it does not ask for one of its own.
      
      Re-registering a name with a new blob is how a retrain ships. A name that
      already belongs to a real model is a 409 rather than a replacement, and an
      adapter whose bytes we do not hold is a 404 that names the upload endpoint:
      a pod sent a content id nobody holds serves the BASE instead, silently, which
      is the failure this whole area has been about.
      
      Identity is (weights, name) here too. An adapter and its base share a `path` by
      definition, so the lookup is by id-or-alias and never by path.
      
      /v1/loras is also pinned local in the gateway. An upload must land in THIS blob
      store — it is where a pod is sent its adapters from, and the content id this
      install hands out has to resolve here. It carries no `model` field, so it
      happened to stay local by accident; that is luck, not design, and the same
      shape of accident as /v1/runpod, which did not stay local and rented a pod to
      deliver a teardown.

      a pool pod keeps the LoRA door open (v0.3.89) · 5fb825ca
      Stefy Lanza (nextime / spora ) authored
      v0.3.88 made the pod FIND the adapter. The live pod then said:
      
          [lora] 'diogene-alpha': adapter sha256:2e820c… is not in this machine's
                 blob store — serving without it
          [vllm] launching: … --served-model-name cyankiwi/Qwen3.8-27B-AWQ-INT4 qwen38-awq
      
      Found, and dropped. A seed names an adapter by CONTENT ID — computed here so
      the pod can be told about it before it exists — and the bytes travel
      separately. They were pushed on the first `acquire`, but the pool's WARM-UP
      request loads the model seconds after boot, long before any acquire. So vLLM
      started without the adapter, and `--enable-lora` cannot be turned on
      afterwards.
      
      Two changes, both gated on the model declaring a `pool`, because a pool is the
      explicit statement that this engine serves several names over one copy of the
      weights:
      
        * a pool engine launches with `--enable-lora` and the capacity flags even
          with no adapter resolvable yet. The flags that must be decided at LAUNCH
          are the capacity ones — the machinery, the slot size, how many adapters may
          be live in one batch — not the list. Opening the door costs a buffer
          allocation; keeping it shut costs a full reload of a 27B on a card billed
          by the hour, the first time an adapter arrives.
        * an adapter is then handed to the RUNNING engine
          (`/v1/load_lora_adapter`, vLLM >= 0.9 behind VLLM_ALLOW_RUNTIME_LORA_UPDATING,
          which the launch sets whenever it enabled LoRA) instead of restarting it.
      
      The restart stays as the fallback and is still reached on every path that
      cannot use the API — an engine started without `--enable-lora`, an older vLLM,
      an adapter whose rank exceeds the slot size. A pod rented an hour ago may be
      running an older image than the one we would launch today, so "it should be
      supported" is not something this can assume.
      
      What this buys: one rented card, one copy of the base model, and QLoRAs added
      or swapped per request by name with no reload.

      the adapter was found by a name a seeded entry does not have (v0.3.88) · 36ed3da0
      Stefy Lanza (nextime / spora ) authored
      v0.3.86 made the pod register `diogene-alpha` as a model of its own, and it
      still answered with the base model's weights. The pod log is the whole story:
      
          [seed] registered qwen38-awq in text_models
          [seed] registered diogene-alpha in text_models
          [vllm] launching: … --model cyankiwi/Qwen3.8-27B-AWQ-INT4
                 --served-model-name cyankiwi/Qwen3.8-27B-AWQ-INT4
      
      No --enable-lora. Both models were registered; the adapter was never collected.
      
      `_sibling_lora_specs` skips "myself" by comparing `entry["id"]` — and the only
      kind of entry a POD holds is a SEEDED one, which carries `alias` and no `id`.
      So the comparison was "" == "", every sibling matched, and all of them were
      excluded. Keyed on alias-or-id now, with identity by object for the one entry
      that really is the model itself.
      
      That fix alone is not enough: a seed names an adapter by CONTENT ID, computed
      here so the pod can be told about it before it exists, and the pod still has to
      receive the BYTES. Until it does, vLLM launches without the adapter. So the
      backend now pushes a model's local adapters to the pod before the first request
      rather than after a failure — vLLM registers adapters when it STARTS, and bytes
      that arrive late cost a full reload of the base model to take effect.
      
      Where an adapter still cannot be resolved, the pod does not serve that NAME at
      all: it is in neither --lora-modules nor --served-model-name, so the request
      404s and the teach-and-retry path picks it up. A 404 is recoverable. The base
      model answering fluently under an adapter's name is not — nothing downstream
      can detect it, which is how this survived two releases that each looked fixed.

      which reads exactly like the orchestrator refusing a name it should know. The
      same call blocked for minutes while a pod booted to receive it. An operator
      could not turn off $3.54/hr from the API. Reproduced here while testing the
      fix: two teardown requests rented two A40s, which is the clearest possible
      statement of the bug.
      
      surya answered 200 with empty pages for a whole document. Three failures in a
      row, each of which had to be fixed:
      
        * its client catches the HTTP error itself and returns a generation with no
          tokens, so the lease check in recognize_image — which only ran in `except`
          — never ran, and the pod address was never re-resolved;
        * the repetition detector was handed that empty string, found no progress in
          it and re-ran the page at a rising temperature, four full paid generations
          per page, `tokens: [0,0,0,0]`;
        * and the page came back as read. We had already measured the ink and said
          there IS something on it; the judgement never reached the response, so a
          client treating an empty read as an unreadable scan consumed roughly a
          thousand documents from its queue and wrote them off.
      
      A page with ink and no text is now `unread`: it goes to the fallback engine
      like any other degraded page, it is listed in `unread_pages`, and a document
      whose every inked page came back empty is no longer a 200 (`ocr.unread_status`,
      502 by default; a partially read document stays 200 with the list).
      
      `bge-m3` and `BAAI/bge-m3` each rented their own A40 — the pool key was
      whichever name the request carried. Keyed on the model ENTRY now, so every name
      for one set of weights lands on one pool.
      
      A client read timeout cannot bound an OCR call: it times each READ, so a
      response that dribbles never trips it and one stayed open nineteen minutes
      against timeout=420. `ocr.request_timeout_s` is the server-side stopwatch.
      
      Chunking: `it-legal` accepts a decorated heading (`**DISPOSITIVO**`) where the
      implementation it ports does not, which splits one more section and leaves a
      short trailing chunk. That was true and undocumented — the table printed the
      strict pattern. Documented now, with `it-legal-strict` named as the
      byte-identical one for re-chunking an existing index. `min_chunk_chars` folds a
      runt chunk into its predecessor, off by default because merging moves a
      boundary, and never silently: the absorbed section label is reported, since
      `conclusioni` is what a party asked for and `dispositivo` is what the court
      decided.

      shared pools: a name is not a path (v0.3.86) · 48fbcf76
      Stefy Lanza (nextime / spora ) authored
      A shared pool is one pod serving several names over one copy of the weights —
      a base model and its adapters. Live, every request naming the adapter got
      
          404 Client Error: Not Found for url: https://…/v1/chat/completions
      
      and kept getting it: the pool keeps the pod warm, so nothing replaced it. The
      pod, asked directly, listed only the base and reported {"loras": []}. Which of
      the two names worked depended on which model happened to rent the pod, so it
      looked intermittent rather than wrong.
      
      Five places decided "same model?" by comparing `path`, and a LoRA's path IS its
      base's path:
      
      * the orchestrator seeded the other pool members with no served name, so they
        arrived with no alias and were registered under their path;
      * the pod's boot seeder skipped the second entry as already known;
      * register_model_runtime did the same, which made teaching a running pod a
        no-op that answered "already known";
      * the engine-side seed filter in main.py did it a third time;
      * and vLLM's service key included the served name, so had the adapter got
        through it would have started a SECOND copy of a 27B on the same card.
      
      Identity is now (weights, name) in all five, and one engine serves one set of
      weights under every name configured for it: the base under its own,
      each adapter through --lora-modules, which --served-model-name must not repeat.
      
      Adoption checks the image, the GPU class and the bearer token — none of which
      say anything about the catalogue. So a pod that cannot serve what the pool
      promises is now TAUGHT: the adapter bytes are pushed, the entry is registered,
      and the same request is retried on the same pod. Renting a second card to serve
      a name the running one can hold is the answer this avoids. Once per pod per
      model; a pod that still refuses is a real failure.
      
      An engine is also relaunched when it does not serve the name asked of it: vLLM
      registers adapters at LAUNCH, and a pod is taught after it boots. Only an
      ANSWERED probe that omits the name forces that — restarting a loaded 27B
      because one probe timed out would be worse than the doubt.
      
      Finally, raise_for_status() discarded the pod's body, which is the whole
      message: it names the models the pod actually has. The caller saw only the
      status line, which reads like a routing fault. The pod's own words now travel.

      embeddings: detecting the head is not having it (v0.3.85) · 4dbe7f0c
      Stefy Lanza (nextime / spora ) authored
      0.3.84 made `_is_bge_m3` see `sparse_linear.pt` on a machine that had
      never downloaded the repo, so the multi-vector backend was finally
      selected on a pod. It then loaded the heads with the same cache-only
      lookup, and `from_pretrained` does not fetch them: it pulls the config
      and the weights the config NAMES, and bge-m3's sparse/colbert heads are
      plain tensors sitting beside the model. So they were still absent, and
      the request came back
      
          HTTP 400  "This model has no sparse head."
      
      which reads as a property of the MODEL rather than of the disk.
      
      `_fetch_repo_file` is the companion to `_resolve_repo_file` for files
      that have to be READ rather than merely detected: cache first, then a
      real hf_hub_download. Offline short-circuits, a local directory is the
      whole answer, and a failure returns None -- the dense path, which the
      caller already handles -- because a head that cannot be fetched must not
      turn into a failed load.
      
      Both halves of this were the same mistake made twice: a cache-only
      helper answering a question about existence on a machine whose cache is
      empty by design. A rented pod is that machine every single time.
      
      Needs a coderai-embeddings rebuild: this code runs on the pod.

      embeddings: a file-based feature check that a pod could never pass (v0.3.84) · 810cb14b
      Stefy Lanza (nextime / spora ) authored
      `_is_bge_m3` keys off `sparse_linear.pt` -- the definitive signal for a
      multi-vector embedder, since plain dense models do not ship one. It asked
      `_resolve_repo_file`, which answers from the local disk and NEVER the
      network. Right for "give me the path", wrong for "does this exist", and
      the difference is invisible until the model has never been downloaded.
      
      On a rented pod it has never been downloaded. The pod is disposable and
      its cache starts empty, so the check ran before anything could satisfy
      it: on every pod, every time, bge-m3 loaded through the DENSE
      sentence-transformers path. The request for sparse was then refused with
      a 400 telling the caller to serve the model on the coderai-embeddings
      image -- which is the image it was already running on. Measured end to
      end on a real A40: 379 seconds, then that.
      
      `_repo_has_file` keeps the local answer first and, only when the file is
      not on disk, asks the Hub for the repo's file LIST: metadata, no
      download, cached once per process. Offline installs short-circuit on
      HF_HUB_OFFLINE, a local directory is taken as the whole answer (asking
      the Hub about a filesystem path would look up a stranger's model of the
      same name), and any failure answers False exactly as before -- a metadata
      lookup must never be able to fail a load.
      
      Needs a coderai-embeddings rebuild: this code runs on the pod.

      runpod: a seeded pod filed every model under text (v0.3.83) · 02a58b2c
      Stefy Lanza (nextime / spora ) authored
      In models.json a model's kind is the dict KEY it sits under. Only the
      ENTRY travels to a pod, and the pod's seeder reads
      
          section = e.get("model_type") or "text_models"
      
      A models.json entry carries no `model_type` -- so every capability pod
      registered every seeded model as a TEXT model, whatever it was.
      
      Found on a real A40 immediately after the gateway fix finally let a
      request reach a pod. It booted in 303s, served /v1/models, listed
      BAAI/bge-m3, and answered:
      
          Model 'BAAI/bge-m3' is a text model and cannot be used for embedding
          generation. Use the text endpoint instead.
      
      Which is the expensive part: nothing looks broken. The routing is right,
      the image is right, the catalogue is right, and the error blames the
      caller for calling the wrong endpoint.
      
      Both seed builders now carry the section -- `capability_seed_entries`
      already had it and dropped it at `out.append(entry)`, and
      `seed_model_env` gets it from the new `entry_model_type()` (by identity,
      then by id, "" on any failure). Stamped on a COPY, so nothing writes a
      field into models.json that this install never had, and an entry that
      already declares its own `model_type` is not second-guessed.
      
      Text pods were unaffected, which is why this survived: a vLLM pod serves
      text, and OCR engines are picked by name rather than registered at all.

      refuses that without accelerate. It is in requirements.txt and in the

      What makes it worth a comment in the file rather than just a line: the
      failure does not look like a missing dependency from outside. The image
      is healthy, the catalogue is right, and the error names the MODEL. On a
      real A40 that cost 303 seconds of boot before anyone could find out, and
      the next error after it ("'BAAI/bge-m3' is a text model") sends the

      gateway: the gate did not know about per-model pods (v0.3.81) · 252cc0bb
      Stefy Lanza (nextime / spora ) authored
      THE /v1/embeddings bug, root-caused on a live 0.3.80 instead of guessed at.
      
      `RemoteGatewayMiddleware` short-circuits on `any_remote_configured()`
      BEFORE it calls `resolve_target`. That gate knew about capability
      endpoints, capability pods and `service_url` -- and nothing about a
      per-model `backend`. So an install whose remote models are all per-model
      RunPod pods answered "nothing is remote", every /v1 request was handed
      straight to the local app, and a GPU-less orchestrator loaded the model
      itself.
      
      Measured on production: POST /v1/embeddings for bge-m3 spent 312 seconds
      downloading from HuggingFace and returned 500, while
      /v1/models/test/state?model=bge-m3 answered `"placement":"pod"` in the
      same process. Both were right. `model_placement` is asked directly by
      every page that reports where a model runs; the gate is asked by the code
      that actually routes, and the two disagreed in silence.
      
      Two earlier fixes aimed at the same report and missed it: v0.3.77 made
      `model_capability()` infer "embeddings" for an entry in the embedding
      section, and the config was given an explicit image and capability.
      Both were necessary and neither was reached.
      
      OCR is why this survived a release: the OCR manager calls
      `placement.choose` itself rather than going through this middleware, so
      the pod-side pipeline worked and made the gateway look fine.
      
      The gate now makes the same two tests `model_placement` makes -- a
      `backend` WITH its block, for runpod and for host. A leftover block whose
      backend was flipped off still does not count, which is how a model's pod
      is meant to be disabled.

      runpod: cancel a boot, release a pod, and stop blocking the server (v0.3.80) · 764b5c59
      Stefy Lanza (nextime / spora ) authored
      Three reports from the same run, all of them about giving pods back.
      
      SCALE BLOCKED THE WHOLE SERVER. The endpoint called into the pool straight
      from the coroutine, so while it walked dozens of (card, region) candidates
      -- a network round trip each -- nothing else was served. /v1/runpod/status
      stopped answering during exactly the operation someone would poll it
      about, which makes a slow rental look identical to an outage. It now runs
      off the event loop and the reply is bounded: after `wait_s` (default 20)
      it answers `pending` with a request id, and the SCALING CONTINUES --
      shielded, because cancelling it would leave a half-made lease and possibly
      a pod. GET /v1/runpod/scale/{id} has the result for a caller that gave up.
      
      A BOOT COULD NOT BE CANCELLED. `_booting` is an integer, not pod objects --
      a pod being created does not exist here yet -- so `shed_now` could not
      see one, count one or stop one. A client that asked for a pod, got four on
      the way and released them was told `kept:0, needed:1, floor:1` and paid
      every boot out in full. A shed now bumps a cancel epoch; an ANTICIPATORY
      boot (warm floor, background growth) checks it during the model load and
      again just before it joins the fleet, and hands its pod straight back. A
      boot a request is blocked on is never cancellable, whatever arrives
      meanwhile: the request is what the pod is for. Booting pods also count as
      capacity in the surplus arithmetic, and the shed reports how many it
      stopped.
      
      A POD COULD NOT BE RELEASED unless some pool floor could be lowered to
      lose it. `'pool:digesta-qwen38' has no runpod block` came from code whose
      own comment says the caller cannot look that key up -- so a live pool is
      now addressable by the key /v1/runpod/status reports. And nothing anywhere
      could terminate ONE pod by id: not an adopted pod, not one left by a
      crash, not one whose pool was reconfigured underneath it. POST
      /v1/runpod/release does, admin-scoped (leasing is bounded and expires;
      terminating a named pod is neither), attributing the spend before it drops
      the pod so the money does not land nowhere.
      
      And the over-provisioning: `ensure_ready` incremented `_booting` by ONE
      and then started `want` boots, so with min_pods 3 three cards were on the
      way while the 15s scaler, `_should_grow` and the parallel-boot cap all
      believed there was one -- each topping up against a deficit already being
      filled.

      ocr: a ruined page is not an error, and nothing was catching it (v0.3.79) · 731ae0e4
      Stefy Lanza (nextime / spora ) authored
      From last night's run: ~97% of a 1,000-document batch came out truncated,
      with no error anywhere. The engine answered 200 every time. Its decode had
      fallen into a loop, run to the token cap emitting the same fragment, and
      the resumer correctly refused to continue a reply that was already
      repeating itself -- so the page was flagged, returned, and indexed.
      
      `fallback_engines` never fired, because it only fires on an exception.
      The same pages read cleanly on another engine (38,055 characters against a
      truncated stub), so the recovery was there the whole time and nothing
      reached for it.
      
      `ocr.retry_degraded` (default "auto") re-reads ONLY the degraded pages on
      another engine and keeps the replacement only if it is not degraded in
      turn. Bounded by construction: a clean document costs nothing, a ruined
      one costs at most a second pass over its ruined pages, and
      `retry_degraded_max_pages` caps even that. The page keeps its own index
      and carries `degraded_retry` saying who re-read it and why; the response
      reports `recovered_pages`.
      
      Degraded means looping or truncated -- the two the engine itself attests.
      NOT a short page, a blank page or an unreadable one: those have their own
      meaning and re-reading them spends a card to be told the same thing.
      
      Which leaves the other half of the report: olmOCR returned 4,046
      characters where chandra read 30,983 on the same page, ending cleanly well
      short of the cap, flagging nothing. The only evidence an early stop leaves
      is the company it keeps, so `retry_short_pages_below` compares a page with
      the DOCUMENT'S OWN median rather than a character count -- a threshold in
      characters would need re-tuning for every language, DPI and layout.
      Default 0, OFF, and deliberately: this signal is inferred where the others
      are attested, and a genuine title or signature page looks identical. A
      short page is also only replaced by a LONGER one.
      
      Off on pods: only the orchestrator can reach another engine's pods, so a
      pod would re-read on the engine that just produced the flag.

      chunk: byte-identity with the implementation this ports (v0.3.78) · 06b7b2e8
      Stefy Lanza (nextime / spora ) authored
      Ran both side by side on the same documents instead of reading the spec,
      and the spec's prose turned out to allow several readings the port took
      differently. Seven divergences in reference extraction, one in sectioning:
      
      * `artt. 163, 164 e 167 c.p.c.` extracted nothing -- the code had to sit
        immediately after the number, so an enumeration lost the whole citation.
        It now resolves to its first article, which is what the indexes hold.
      * `art. 2055-bis c.c.` extracted nothing (only a space was tolerated before
        the suffix); the hyphen is now kept in the key, a space still squeezed out.
      * `art. 2043 cod. civ.` extracted nothing -- the code spelled out was in the
        normalisation table but not in the pattern.
      * `articolo 2043 c.c.` and `art. 2043 della c.c.` extracted a reference the
        original does not. Looking like an improvement does not make it one: it
        puts keys in the field that the corpus it will be matched against lacks.
      * `legge 241 del 1990` extracted nothing; `l 241/1990` without the dot
        extracted one. Both inverted.
      * `art. 360` with no code came back as `art.360`, and `d.p.r. 115/02` as
        nothing -- the two already reported.
      
      And the off-by-one, which was none of the things it looked like. Section
      bodies were not stripped, so merging two adjacent same-label sections (a
      filing opening its conclusions twice) joined a body ending in a blank line
      to the next, turning a line break into a paragraph break -- packed as
      `\n\n` rather than riding inside one piece. Exactly one character, on
      exactly the documents that merge. Empty sections were also kept, spending
      a `parent` id and shifting every id after it.
      
      Verified by diffing chunk-for-chunk over 63 generated documents covering
      CRLF, repeated headers, enumerations, two-digit years and degenerate input:
      zero divergences in text, section, parent and norm_refs.
      
      The one deliberate difference is `**FATTO**`, which the original does not
      match and `it-legal` does. `it-legal-strict` is added for re-chunking a
      corpus indexed with the original, where a boundary that moves makes the new
      index incomparable with the old.

      * `art. 360` with no code came back as `art.360`. Every procedural code has
        an art. 360, so an unqualified number is not a citation -- it files three
        different articles under one exact-match key, which is the one thing this
        field exists to prevent. The code suffix is now required.
      
      * `d.p.r. 115/02` extracted as nothing, because the year was pinned to four
        digits. Two to four now, kept verbatim: expanding `02` to `2002` would
        split one act across two keys depending on the source's style.
      
      The spec's prose allowed both readings; it now says which.

      runpod: an embedding model on a capability pod had no capability (v0.3.77) · e3dc237b
      Stefy Lanza (nextime / spora ) authored
      Switching a model's `runpod.engine` from `coderai-vllm` to `coderai` -- the
      correct setting for a capability pod -- silently removed its capability.
      `_CODERAI_SERVER_ENGINES["coderai-vllm"]` had been supplying the classification;
      plain `coderai` supplies none, and `model_capability()` returned "".
      
      Both halves of the failure follow from that:
        * the front could not classify the request, so the model was loaded LOCALLY
          on a GPU-less orchestrator;
        * default_capability_image("") is "", so a blank image field raises
          "set `image` on the runpod block" at provisioning time.
      
      It presented as "tries to load on the wrong machine", which is a long way from
      "this entry has no capability".
      
      The cause: model_capability() receives a BARE DICT, and _model_entry_for()
      iterates md.values() -- it matches inside `embedding_models` and discards the
      section key. Nothing had ever told it that an entry in `embedding_models` is an
      embeddings model. Now it asks: by object identity first (the dict the loader
      holds), falling back to the id so a copied or rebuilt entry still resolves, and
      returning False on any failure because a capability GUESS is never worth an
      exception in a placement path. An explicit `capability` field still wins, which
      is what that field is for.
      
      Only `embedding_models` is inferred, deliberately. The other sections work
      today, and remapping them all to fix one would change placement for every model
      kind -- a blast radius this does not need. A test asserts the inference does not
      reach into text_models, image_models, video_models or tts_models.
      
      Found by a user report ("broken -- front loads bge-m3 locally on the GPU-less
      host; not in /v1/models") after I made exactly that config change. I had already
      noted this gap when the capability came back empty during the switch, said it
      was worth raising rather than working around, and then worked around it in the
      config anyway -- which is how it reached production.

      chunk: POST /v1/chunk, and the OCR pipeline for all three VLM engines (v0.3.76) · 29233812
      Stefy Lanza (nextime / spora ) authored
      RETRIEVAL CHUNKING. A new endpoint that splits a document into the pieces an
      index stores, with the document's structure decided per request by a named or
      inline template. NOT embedding windowing: `embed_long_input` makes ONE input fit
      a model window and pools it into ONE vector; this produces MANY chunks, each
      indexable, each with its section, parent and references. It never pools and
      never drops text.
      
      Pure CPU -- token counts are characters / chars_per_token, so no tokenizer is
      loaded and no model, GPU or pod is involved. Every image serves it, light-core
      ones included, and a test asserts no torch/transformers import creeps in.
      
      The packing loop is reproduced verbatim, including the parts that look
      improvable: paragraphs joined with "\n\n" (hence the `+ 2`), and an overlap that
      is a RAW CHARACTER TAIL which may begin mid-word. Changing any of it moves every
      existing chunk boundary, and then a re-chunked index cannot be compared with the
      one it replaces.
      
      `conclusioni` is its own label and is never folded into `dispositivo`: in a
      ruling the dispositivo is what the judge decided, in a filing the conclusioni
      are what a party ASKED FOR, and merging them would let a demand surface as a
      holding.
      
      TWO DEVIATIONS FROM THE SPEC, both recorded in the source where someone
      comparing against the original will look:
      
        * The ceiling is target + overlap + 2 (3682), not the 3680 the prose states --
          which agrees with the spec's own "observed max is 3682" two lines later.
          Asserting 3680 would fail a correct port.
        * The verbatim patterns cannot match `**FATTO**`, yet the fidelity list asks
          for that case. The line-anchored alternatives are widened at BOTH ends
          (`^[\s*#>_]*fatto[\s*#>_]*$`), which is how the patterns that already coped
          spell it. Purely additive: every line that matched still matches, so no
          existing match moves -- but a document whose headers were emphasised used to
          fall back to flat chunking and now gets sectioned, so ITS chunks change and
          it needs re-chunking.
      
      FORWARDABLE, with the hazard that comes with it. /v1/chunk rides the EMBEDDINGS
      capability: chunks are on their way to be embedded, that image is full-core so
      it carries the chunker, and a capability of its own would be one nothing
      advertises -- or would rent a GPU to run a regex split. It was first classified
      as deliberately local on the grounds that it is cheap; that was the wrong lens,
      since the orchestrator is the box that was OOM-killed today, so WHERE the CPU is
      matters more than how much there is.
      
      But a template registered HERE does not exist on the remote: forwarded by name
      it returns 404, or worse matches a DIFFERENT template with the same name and
      returns different boundaries silently. So a named non-builtin template is
      resolved and INLINED before the request leaves. The hook never raises -- a body
      it cannot parse is forwarded untouched -- because a rewrite that can throw would
      take down every forwarded request, not just a chunk one.
      
      THE OCR PIPELINE NOW COVERS ALL THREE VLM ENGINES, not just surya. Leaving
      chandra and olmOCR on the orchestrator was an asymmetry rather than a design:
      surya needed a 1.6 GB client venv baked in, while those two speak only HTTP in
      served mode (PIL + requests, already in the main venv), so for them the pod side
      costs nothing beyond the rasteriser. Two bugs fixed on the way, both of which
      would have produced plausible WRONG text rather than an error: the dispatch
      hardcoded `engine: "surya"` in the form it posted, and the pod env was
      surya-shaped throughout -- a chandra pod was told to run surya against chandra's
      model id. Per-engine tuning and per-engine licence acceptance now travel.
      
      AND THE LOG THAT CAUSED A MISDIAGNOSIS. One pod request walks a candidate list
      until a (card, region) pair has capacity, and each attempt printed
      "provisioning pod for ...". 312 attempts for 10 pods therefore read as runaway
      provisioning and was reported as such. It now says "trying candidate N/M for
      ONE pod", so the shape of the list is visible instead of inferred.
      
      What these tests CANNOT do is prove byte-identity with the implementation this
      ports -- that needs fixtures from a live corpus. They prove the documented
      behaviour on each path; identity is what decides whether a re-chunk is safe and
      it is still outstanding.
      
      Suite at the 25 pre-existing failures.

      ocr: say which pipeline actually ran (v0.3.75) · 35a8304e
      Stefy Lanza (nextime / spora ) authored
      `_read_on_pods` returned None in silence when no pod could serve, and the caller
      then read the document locally. So an install configured for the pod-side
      pipeline could fall back on EVERY request and look exactly like a success: the
      OCR works, the text is right, and the operator concludes the new path is working
      when it has never run once. A test that cannot distinguish the two paths proves
      nothing about either.
      
      Both paths now announce themselves in one line -- the fallback naming the CAUSE
      ("placement answered 'local' — nothing rented, or the pool could not serve")
      rather than only the effect, and the success saying the pages were rasterised
      and read on the pods rather than here.
      
      Found while answering "can I launch the new OCR to test?", which is exactly when
      it mattered: the answer was yes, and the test would have been uninterpretable.

      embeddings: chunk against the model's REAL window, and report it everywhere (v0.3.74) · bd855536
      Stefy Lanza (nextime / spora ) authored
      Two gaps in 0.3.72/73, both of which left chunking looking enabled while doing
      nothing useful.
      
      THE THRESHOLD WAS A NUMBER SOMEONE TYPED.
      
          max_len = int(_emb_cfg.get('n_ctx') or _raw.get('n_ctx') or 8192)
      
      Set n_ctx above what the model accepts and the windows are built too big; the
      tokenizer then truncates each window at its real limit anyway and chunking
      silently stops protecting anything -- the same invisible loss this code exists
      to remove, reached through a config typo instead of a missing feature. The
      window is now min(configured, tokenizer.model_max_length), with one trap
      handled: HuggingFace sets model_max_length to a sentinel near 1e30 when the
      checkpoint declares none, and believing that means never chunking at all, so a
      value that large is read as "unknown" and the caller's number stands. Same clamp
      on the sentence-transformers path, taking the smaller of max_seq_length and the
      tokenizer's own limit.
      
      THE MULTI-VECTOR PATH COLLECTED THE COUNTS AND DROPPED THEM. It builds its own
      response, so the dense path's report did not cover it -- chunking was invisible
      on exactly the path that needs it most, which is the bug this feature was
      written to fix. It now reports
      
          "chunked": {"windows": [...], "pool": ..., "token_limit": N}
      
      and logs the limit with the merges applied. `token_limit` is deliberate: it is
      what makes a WRONG n_ctx visible rather than merely ineffective.
      
      46 tests. Suite at the 25 pre-existing failures.

      embeddings: multi-vector on the image that can serve it, and a 400 where it cannot (v0.3.73) · da2859f0
      Stefy Lanza (nextime / spora ) authored
      bge-m3's sparse and colbert come from linear heads (sparse_linear.pt /
      colbert_linear.pt) applied to the last hidden state -- a transformers forward
      pass, not an embedding server's output. Two consequences that were both silent:
      
      A DENSE-ONLY BACKEND NOW SAYS SO. `embedding_types` was simply ignored outside
      the native path: a caller asking for sparse got a normal-looking response with
      only `embedding` in it, its hybrid retrieval then ran on half the signal, and
      the result was merely a worse score -- which reads as a model problem, not a
      configuration one. Now a 400 that names the cause, where it DOES work
      (coderai-embeddings), and why the vLLM image cannot: that image is LIGHT core
      with no torch in its main venv BY DESIGN, so _load_bge_m3 could not even import.
      Dense-only requests are untouched.
      
      MULTI-VECTOR LONG INPUTS ARE WINDOWED. 8192 tokens is ~6000 words, so this bites
      on whole documents rather than passages -- and when it bit, the tokenizer's
      `truncation=True` kept the opening and said nothing. Each type is merged the way
      the encoder already merges WITHIN a window, which is what makes these choices
      defensible rather than invented:
      
        dense    mean, RE-NORMALIZED. It is an L2-normalized CLS vector and a mean of
                 unit vectors is not one; cosine similarity on a non-unit vector is
                 quietly wrong.
        sparse   MAX per token id -- the encoder max-pools per token id already
                 (scatter_reduce amax), and a term's weight should be its strongest
                 occurrence, not an average diluted by the pages that never mention
                 it. A test guards against someone later tidying max into mean.
        colbert  CONCATENATED: max-sim scores each query token against ALL document
                 token vectors, so every content token of every window belongs.
      
      `embed_long_input=truncate` keeps the old behaviour explicitly, and `first`
      keeps only the opening window, for an operator who would rather have that than a
      merge.
      
      Also removes three customer references I had put in shipped profile comments,
      two of which went out in 0.3.69. A capability must be scoped and justified by
      what it does, never by one install's needs, and a customer name does not belong
      in a released image. The measurements keep their force without the attribution:
      "hybrid retrieval wants dense and sparse from one pass", "a production fleet",
      "a GPU-less orchestrator".

      embeddings: chunk a long input instead of silently keeping its opening (v0.3.72) · 7f598fdb
      Stefy Lanza (nextime / spora ) authored
      Only the GGUF path ever chunked. Every other backend passed `truncation=True`
      and returned a confident UNIT vector of roughly the first page of a long
      document, with nothing in the response to say so:
      
          truncation=True, max_length=1800        # GME-Qwen2-VL, a hardcoded ceiling
          truncation=True, max_length=max_length  # bge-m3 native
          model.encode(texts, ...)                # sentence-transformers, its own cap
      
      Not an error -- a wrong answer that looks right, which is the failure mode this
      codebase keeps paying for. A caller had no way to tell an embedding of a
      document from an embedding of its first page.
      
      Now a long input is windowed to the model's real limit, every window of every
      input goes to the backend in ONE batch (a 40-page document must not become 40
      round trips), and the chunk vectors are mean-pooled AND RE-NORMALIZED: mean
      pooling unit vectors does not give a unit vector, and cosine similarity on a
      non-unit vector is quietly wrong, so the renormalization is part of the contract
      rather than a tidy-up.
      
      Tunable per-model -> env -> default, the convention the admission gate already
      uses:
          embed_long_input  chunk | truncate | error   (default chunk)
          embed_chunk_pool  mean | first               (default mean)
      
      `truncate` stays reachable and is now DELIBERATE: for a short-text encoder a
      40-page input is usually a caller bug, and an operator may prefer the old
      behaviour to a vector pooled from forty windows. `error` says so out loud.
      
      AND IT IS REPORTED: resp.chunked = {"windows": [...], "pool": ...} whenever any
      input needed more than one. Replacing a silent truncation with a silent pooling
      would have been the same bug with a better answer.
      
      The GGUF path's hard-won guard now covers every backend: each window is
      RE-ENCODED and shrunk until it verifiably fits, because a detokenize->retokenize
      round trip is not token-count-stable (specials and BOS are re-added) and a
      window cut at exactly the limit can re-inflate past it -- which is how that path
      first tripped llama.cpp's GGML_ASSERT.
      
      Wired: sentence-transformers, and GME-Qwen2-VL (windowed BEFORE the chat prompt
      is built around the text, since the processor's own truncation would cut the
      template's closing tokens as readily as the body). GGUF already chunked.
      
      NOT wired, on purpose: the CLIP family (clip, geoclip, vpr) takes 77 tokens BY
      DESIGN -- those encoders embed captions, not documents, and pooling forty
      windows of a contract into a CLIP vector would be meaningless. A test asserts
      this so "chunk everywhere" is not later read as "chunk where it makes no sense".
      
      NOT wired, needs a decision: bge-m3's native multi-vector path returns dense
      PLUS sparse and colbert. Dense mean-pools fine, but sparse would need
      max-merging per token id across windows and colbert would concatenate per-token
      vectors. Those are retrieval semantics, not a mechanical change, and improvising
      them would degrade search in a way that looks like a model problem.

      autoupgrade: a host that is never idle now upgrades at midnight (v0.3.71) · 7a6234ce
      Stefy Lanza (nextime / spora ) authored
      The timer's own comment promised "a restart only happens on a real upgrade, and
      only when the fleet is idle (or after MAX_DEFERRALS hours of never being idle)".
      The second half could not happen:
      
          guard_idle || exit 0          # a busy host exits HERE
          ...upgrade...
          N=$(cat "$DEFERRALS" ...)     # the counter only ever incremented HERE
      
      So on a busy host the script left before the image was even pulled, the counter
      the force depends on never advanced, and MAX_DEFERRALS was unreachable. Measured
      on the Digesta orchestrator 2026-10-14: 24 skips in one day, `deferrals` still
      0, two versions behind, and 0.3.68 landed only because the host happened to be
      idle at 17:01.
      
      Now a busy skip COUNTS, and at MAX_DEFERRALS the script books a forced upgrade
      for the next midnight. The 00:00 tick of the existing hourly timer fires it, so
      there is no second unit to install and nothing stranded by a reboot. Midnight
      because it is the cheapest hour to interrupt a business-hours workload and a
      time an operator can predict without reading the script.
      
      Four things that each had a way to go wrong:
        * booked ONCE, not re-booked on every busy tick -- otherwise the deadline
          walks forward forever and never arrives;
        * a corrupt deadline file is discarded, not obeyed: garbage must not read as
          "the time has passed" and restart the service, nor sit there blocking a
          fresh booking;
        * a forced run does not defer at the restart step either -- deferring there
          would put it back where the booking was made;
        * MAX_DEFERRALS=0 keeps its old meaning (wait for an idle moment, however
          long, never force), so an install that did not opt in is unchanged.
      
      The booking is announced in the config banner of every later run and cancelled
      by deleting one file, because a forced restart that nobody saw coming is worse
      than a late upgrade.
      
      16 tests, and the ones that matter are behavioural rather than source-matching:
      they extract the real arm_midnight_force and force_due from the script, run them
      under bash against a temp state dir, and assert the timestamp really is local
      midnight and that force_due flips at the right moment. A test that restates the
      logic only proves it agrees with itself.
      
      Suite at the 25 pre-existing failures. NOT installed on Aruba: that copy is
      byte-identical to this one and runs hourly, so overwriting it mid-run would be
      editing a running script.

      ocr: the pod image chooses where the pipeline runs (v0.3.70) · 5813524c
      Stefy Lanza (nextime / spora ) authored
      An OCR VLM needs a model server AND the surya pipeline that drives it. Which
      machine runs the second one is now chosen by the pod IMAGE, and by nothing else:
      
        coderai-vllm      the pod serves the model; the ORCHESTRATOR rasterises every
                          page and sends a ~1.06 MB base64 PNG per A4 page at 250 DPI
                          -- and again for every resumption round. Unchanged.
        coderai-vllm-ocr  the pod carries surya's client venv and pypdfium2, so it is
                          sent a ONE-PAGE PDF (~474 KB, 1.7 ms to split here against
                          ~105 ms to rasterise) and reads it on the card with its own
                          vLLM over loopback.
      
      A separate `pod_ocr_pipeline` flag was built first and removed. Two switches
      that can disagree is the invisible mismatch that cost three rounds of blaming a
      pod image for orchestrator bugs; choosing the image IS choosing the mode, it
      already lives in models.json and on the model page, and an image that cannot run
      a pipeline can no longer be asked to.
      
      PAGE-LEVEL FAN-OUT IS UNCHANGED. One page is one request in both modes --
      `placement.choose` picks an upstream per page -- so every pod in the pool shares
      the work and none owns a document. Sending a whole PDF to one pod would turn an
      8-way parallel read into a serial one, which is why the split is per page.
      
      THE TUNING TRAVELS, not just the wiring. surya_dpi, the page budget, the
      continuation count, the repeat-detector thresholds, langs, the page window, the
      resident cap. Every one was set in response to a measured failure, and a pod
      reading pages at surya's own defaults would be indistinguishable from the
      "pre-fix pod image" that was wrongly blamed three times. A test cross-checks
      every CODERAI_OCR_* the plan sends against what config.py actually reads: a
      variable sent and never read is a setting that silently does not apply, which is
      the exact shape of two bugs found earlier today.
      
      FALLBACK, and what it refuses to hide:
        * no pod rented -> the WHOLE document is read locally, not half each way (a
          document read by two pipelines is the hardest kind of result to explain);
        * a pod answers 500 -> raised, not quietly re-read here; a broken fleet must
          stay visible;
        * the image lacks the pipeline -> the orchestrator does what it always did.
      
      The image, built and verified (14306 MB, /healthz OK):
        venvs/surya  1.6 GB  torch 2.14.1+cpu cuda=None + ultralytics 8.4.177
        venvs/vllm    11 GB
        main venv:   pypdfium2, and no torch at all (light core intact)
      A CUDA torch in the surya venv would add ~4.2 GB AND put surya's small local
      line detector on the card serving the model; the venv check asserts
      torch.version.cuda is None so a resolve cannot quietly undo it.
      
      35 tests. Two flaws of my own that they caught: four passed alone and failed in
      the suite because they patched sys.modules while `from codai.models import
      placement` resolves the name as an attribute of the already-imported package --
      now patched on the real module, verified in both orders; and _plan_env used a
      hand-rolled stub that tested the stub, now built from a real
      RunpodModelConfig. Suite at the 25 pre-existing failures.
      
      NOT YET EXERCISED AGAINST A REAL POD: the orchestrator path has only run against
      fakes, and the image is local -- not pushed or signed.

      runpod+ocr: fill a warm floor in waves, and put the OCR pipeline on the pod image (v0.3.69) · 4fe78dbc
      Stefy Lanza (nextime / spora ) authored
      THE WARM FLOOR. A declared floor of 8 took ~40 minutes to exist. Measured on the
      Digesta orchestrator, one pod per scaler pass at ~5 minutes each:
      
          15:15:27  warm floor 8, 2 pod(s) healthy — renting one
          15:21:12  warm floor 8, 3 pod(s) healthy — renting one
          15:32:41  warm floor 8, 4 pod(s) healthy — renting one
      
      Two causes. First, `maintain()` rented exactly one pod per pass, gated on
      `not self._booting`. A floor is a DECLARATION, not a prediction -- min_pods,
      keep_warm or a client lease already said how many should be warm -- so the
      deficit is filled at once, bounded by the model's existing
      `scale_up_max_parallel_boots` (no new knob; it already means "how many pods may
      be booting at once"). Second, `_provision_one` is "Blocking (minutes)" and this
      called it INLINE from the scaler loop, so one warm boot stalled that loop --
      including the registry heartbeat that lives in it and runs every 60s. A stalled
      heartbeat is exactly what makes a sibling treat our booting pod as abandoned,
      which 0.3.68 made load-bearing. Warm boots now run on their own threads.
      
      Adoption loops too (a restart orphans the whole fleet; eleven pods at one per
      tick took six minutes), but BOUNDED two ways: `_adopt_shared_pod()` returning
      True is a report, not a guarantee -- it can succeed without the pool gaining a
      healthy pod -- and the first `while ... and adopt()` form span forever the first
      time that happened, taking the scaler thread and the heartbeat with it. At most
      `deficit` attempts, and stop when an adoption does not raise the count. A pass
      that adopted rents nothing: renting beside a fresh adoption is how one job pays
      for two cards.
      
      THE IMAGE. coderai-vllm-ocr existed to pin vLLM 0.20.1, the version surya
      spawns, because a page of crisp Italian came back from 0.27.1 with one U+FFFD
      per accented letter. That was the wrong conclusion from a real measurement:
      surya-ocr-2's tokenizer is BYTE-level, and the fleet has been reading accented
      Italian on 0.27.1 ever since. Two images serving the same weights on two vLLMs
      is an invisible difference, and it cost three rounds of blaming the pod image.
      So the pins are now IDENTICAL and the check READS the fleet's pin from disk
      rather than restating a version -- bumping profiles/vllm cannot silently leave
      this image behind.
      
      What distinguishes the image instead is the OCR PIPELINE on the pod: the surya
      client venv beside the model, plus pypdfium2 in the main venv, so a page is
      rasterised and read on the card rather than crossing the network as a ~1 MB
      base64 PNG (and four more times over for a page resumed four times).
      
      CPU TORCH, and it is the whole image-size story. Measured in a resolved surya
      venv: nvidia 3196 MB + torch 1175 MB + triton 896 MB = ~5.3 GB of CUDA stack,
      for a venv whose only local torch workload is surya's small line detector. On
      the pod the GPU is already committed to serving the model, so giving the
      detector the card would take VRAM and SMs from the thing that matters; on a
      GPU-less orchestrator it can never execute at all (cuda available: False today
      while its surya venv carries cu130). ~280 MB instead of ~5.3 GB, and the venv
      check asserts torch.version.cuda is None so a resolve cannot quietly add 5 GB
      back.
      
      THE DETECTOR rides that same CPU torch, which is why it costs ~30 MB rather
      than a third torch. detect.py tries ultralytics in-process first (every existing
      install is unchanged) and falls back to codai/ocr/workers/detect_worker.py in
      whichever venv has it -- surya's first. A detector that cannot be reached looks
      like a MISSING detector (the ordinary 503), never a broken install. No weights
      are baked: detect_model_path defaults to "" and a released image must contain no
      models, configs, keys or secrets.
      
      Tests: 17 warm-floor (+4 for the spin), 14 detector. Four older tests encoded
      the decisions this reverses -- two asserted the 0.20.1 pin (replaced by one
      requiring the two pin files to be identical), one asserted the warm floor "must
      still be single-flight", one counted a source string globally and could not tell
      intent-held-spelling-changed from a regression (now per path). Suite at the 25
      pre-existing failures.
      
      NOT BUILT and NOT USABLE YET: nothing has resolved surya-ocr + pillow<11 +
      torch+cpu + ultralytics together, and the orchestrator cannot drive a pod-side
      pipeline until the dual mode lands.

      runpod: a restart mid-boot froze the pool and hid its own pods (v0.3.68) · 143b86fa
      Stefy Lanza (nextime / spora ) authored
      Observed live: six pods billing on the RunPod account, none in coderai's
      interface, and "another engine is booting a pod for 'datalab-to/surya-ocr-2' --
      waiting for it" every fifteen seconds for seven minutes. Nothing was booting. A
      deploy had restarted coderai mid-boot, leaving that pod's URL-less registry
      entry with no owner.
      
      Three fixes, three different mistakes:
      
      1. sibling_is_provisioning() judged the entry's liveness against
         REAP_GRACE_SECONDS (1200s). That constant answers how long the REAPER waits
         before killing an unowned pod -- a different question. The registry has a
         60s heartbeat, so a dead owner is detectable in seconds. Now
         PROVISION_STALE_SECONDS (180s = three missed beats).
      
      2. The sibling check ran BEFORE _adopt_shared_pod(), so the recovery path for
         orphaned pods sat behind the marker that orphaning creates. Five running,
         registered, billing pods were never adopted. Adoption now runs first: a pod
         already serving this pool beats waiting for a boot and beats renting.
      
      3. A pod registered at CREATION recorded no $/hr -- the rate was passed only at
         the ready-registration 80 lines later -- so a boot interrupted before ready
         could only be reaped with "the registry records no rate for it". The price is
         known at creation. Also, hourly_usd is now carried over on re-registration
         like image and gpu already were: an adoption that did not know the rate
         turned a billing pod free.
      
      14 tests, including the exact live entry (url-less, 910s stale) as a case.
      test_runpod_client_scale's adopt-before-rent assertion was pinned to the old
      source spelling; updated to assert the intent, which is now stronger.

      ocr: rasterise PDFs one document per process (v0.3.67) · 9c643e75
      Stefy Lanza (nextime / spora ) authored
      0.3.66 serialised every pdfium call behind a lock, because pdfium permits one
      caller at a time and calling it concurrently corrupts its state into "PDFium:
      Data format error" on valid documents. Correct, and it made rasterisation
      single-threaded for the whole install -- a ceiling of about one core.
      
      pdfium IS safe one-document-per-process, so `ocr.raster_workers` (0 = auto at
      half the cores capped at 4, 1 = in-process under the lock) hands documents to
      worker processes. Measured on 12 concurrent 47-page PDFs at 150 DPI: 21.9s ->
      10.3s, 2.13x. Not 4x -- the parent is single-threaded receiving the pixels and
      rebuilding the images, and ~4.5 GB crosses the pipes. The ceiling is the parent.
      
      Three things this had to get right, each of which cost a bug first:
      
      - A worker is borrowed per CHUNK, not per document. The caller OCRs each window
        between pulls, which takes far longer than rasterising it, so holding a worker
        across that would idle it for most of its tenure and cap the install at
        `raster_workers` concurrent documents -- worse than the lock it replaces.
      
      - A pool that cannot start must cost nothing. The first version waited 300s for
        a worker that could never arrive (missing script), stalling every document for
        five minutes: the optimisation becoming an outage, which is the exact failure
        its test was written for. Creation failure is now remembered rather than
        retried per document, and a busy pool falls back in-process after 30s.
      
      - Workers are executed, never imported. `import codai.ocr` costs 377 MB and
        1.5s via codai.models.manager -> litellm; paying that per worker, in the
        subsystem whose other half exists to bound memory, would be self-defeating.
        The worker imports pypdfium2 and PIL only, ~25 MB. This is why it is not a
        ProcessPoolExecutor: spawn pickles a function by qualified name and re-imports
        the package to find it.
      
      Also fixes a cost 0.3.65 introduced and nothing but a stopwatch would surface:
      pricing a document called `pdf[i].get_size()` per page, which LOADS each page
      object -- 593 ms for a 47-page document, paid UNDER THE LOCK, so every document
      in the install queued behind every other being priced.
      `pdf.get_page_size(i)` reads the same numbers from the page tree by index.
      page_estimate: ~600 ms -> 9.6 ms.
      
      Every failure path degrades to a correct in-process render: no pool, a dead
      worker mid-document, a missing script, an unusable module, an abandoned
      document. Correctness never depends on the optimisation working.
      
      87 tests across the budget and pool suites. Full suite at the 25 pre-existing
      failures.

      ocr: pdfium is not thread-safe, and 0.3.65 found out in production (v0.3.66) · 43cc57a5
      Stefy Lanza (nextime / spora ) authored
      0.3.65 moved PDF rendering into asyncio.to_thread so a long document would stop
      stalling the event loop. That was correct in intent and broke OCR within the
      hour: until then `load_pages` ran ON the loop, which serialised every
      rasterisation BY ACCIDENT. Removing the accident let documents into pdfium
      concurrently, and pdfium permits exactly one caller at a time. Concurrent use
      corrupts its state and reports
      
          failed to rasterise PDF (pypdfium2): PDFium: Data format error
      
      on documents that are perfectly valid -- so the failure accuses the input, and
      the operator goes looking at their files. Three valid Diogene PDFs that poppler
      parsed cleanly were rejected this way.
      
      Measured: 1 document OK, 8 concurrent = 8 failures, 24 = 24 failures. After the
      fix, 48 concurrent 47-page PDFs all return 47 pages.
      
      Every pdfium call -- document open, page size probe, page render -- now runs
      under one lock, held per CALL rather than per document so documents still
      interleave page by page instead of queueing behind each other's full length.
      Rendering still happens off the event loop, so this is strictly better than
      0.3.64, which serialised AND blocked the loop.
      
      Cost, stated plainly: rasterisation is single-threaded, a ceiling of about one
      core. That is what 0.3.64 effectively was, so it is not a regression against it.
      Rasterising in a process pool (pdfium is safe one-document-per-process) is the
      scalability fix and is deliberately not bolted onto this hotfix.
      
      Two process lessons, in the tests so they outlive the memory of this:
      - this path is only ever exercised concurrently, so testing it sequentially
        tests the one case that cannot fail. I shipped it tested sequentially.
      - the error STRING predated the change, and I used that to argue the behaviour
        did too. "This message is not new" is not evidence of "this is not new".
