A read a person started now runs as interactive work of their account, and
the document jobs as background work of theirs, so the reader's queue can
order and cap them. When the reader is busy or stopped before it answered,
a lab scan, label read or document read fails with aiRuns.readerBusy (503,
nothing read or charged) instead of a misleading unreadable-file error, and
the index and summary jobs throw so the queue runs them again rather than
recording an outcome about the document.
A text read that crossed the isolated reader's memory or time bound came
back as a plain read error, which the index job records as decrypt-error,
so the document said its stored file could not be opened. The local
extractor now answers resource-limit for PdfResourceLimitError, the index
records it under that name, and the detail view says the PDF is too large
or complex to read here, in every locale. Like the thumbnail's refusal of
the same bytes it is final: nothing retries it on its own.
The health ledger already counted every failed call and paused a provider
that kept failing, with a pause that grows. A paused provider only moved to
the tail of the chain, though, and the tail is still walked: a chain whose
only entry answered every call with reasoning and no answer was called by
every background job regardless.
A walk for background work (surface "job") now leaves out every provider
the ledger has benched until its window lifts; the local floor only once
it is paused, past a brief backoff. One ai.chain.background_paused line
per window says so. A person's own call still reaches the provider at the
tail and reports its own error. The ledger is in Postgres, so the bench
holds across workers and restarts.
The status, briefing and document-index paths refunded a failed call in
full, so background spend on replies without an answer never reached the
day's token ceiling. A failed chain now carries the tokens its hops
reported (tokensSpent) and those paths charge them.
The two clients share one answerless step (askAgainUnreasoned), which
keeps both inside the source size ratchet; its baselines go down.

Under Node, pdf.js runs its worker in the server process and keeps it on
a global, and whichever copy of pdf.js opens a document first owns that
global until a restart. The local text read went through pdf-parse, which
pins its own pdfjs-dist 5.4.296; the rasterizer uses the app's 6.4.299. A
text read first made every later rasterization fail with "The API version
does not match the Worker version" (thumbnails raster-failed, the vision
read of a scan 422), and a rasterization first made every later local text
read fail, which left the document out of the search index with nothing in
the logs.
src/lib/documents/pdfjs.ts is now the one place pdf.js is loaded and
opened, with one set of options (asset directories, no eval, no system
fonts). The text read walks the pages with getTextContent and lays the
text out the way pdf-parse did with the options it was called with: line
breaks, tabs between far-apart items, a blank line after each page, the
200-page cap. Text extracted from the PDF fixtures and from generated lab
tables, encrypted files and doctor reports is identical before and after.
A failed text read now emits documents.local_extract.failed with the
error pdf.js threw, and annotates the index event with it, instead of
returning a bare error.
The report tests read PDF text through the same reader. Two tests, one per
order, run a text read and a rasterization in one process; both failed
before this change.
Refs #1277
Local text extraction went through pdf-parse, which pins its own
pdfjs-dist (5.4.296) beside the app's (6.4.299), and both copies take
their worker from globalThis.pdfjsWorker. Whichever ran first in a process
broke the other: after a text extraction every raster failed with "The
API version "6.4.299" does not match the Worker version "5.4.296""
(thumbnails raster-failed, vision reads of a PDF 422 extractFailed), and
after a raster the text extraction failed and the local content index
stayed empty without a trace.
extractPdfText now reads the text layer with getTextContent on the
pdfjs-dist the rasterizer uses, so only one pdfjs runs in the server.
Pointing pdf-parse at 6.4 instead is not enough: its destroy() calls
PDFDocumentProxy.destroy(), which pdfjs 6 no longer has, so every
document would skip its teardown. Two tests run text and raster in one
process, each order in its own file.
The token ledger keyed every day on UTC while the daily briefing and the
other per-day generations run on the account's local day, so east of UTC
the first generations after local midnight were refused against the
previous day's spent ceiling. The budget day is now the calendar day in
the account's time zone; each request still resolves it once and books
its reservation and reconcile on the same row. The medication extraction
reads relative phrases against the same local day, the operator's spend
card shows the operator's own day, and the limit copy says the budget
resets at midnight in the person's time zone.
A document uploaded with aiRead=defer is now indexed locally by any
automatic path, because the indexer reads the marker from the row rather
than from the job. Index all for search leaves such documents out and no
longer counts them. Only an explicit Read with AI or Generate summary ends
the hold.
Uploads that send a body keep their slot of the hourly limit, duplicates
included; handing it back let a token send the same bytes under id after
id for free. One document takes at most 20 further source ids, beyond
which the upload answers 409 documents.inbound.sourceAliasLimit. The
query-string key check is metered on the lookup allowance it shares with
GET /api/documents/inbound/source.
Refs #1038
A narrow `documents:write` token, minted cookie-only at
`POST /api/tokens/documents` and accepted by the vault upload route alone.
A scoped caller draws on its own hourly bucket per token
(`DOCUMENT_UPLOAD_LIMIT_PER_HOUR`, default 120) and gets a receipt
`{ id, duplicate }` instead of the stored row.
Uploads take optional `sourceSystem` / `sourceId` fields. The source key is
unique per account across live and deleted documents, and the tombstone
purge carries it to a small ledger, so re-sending a document the owner
deleted answers 200 `deleted: true` and stores nothing. `aiRead=defer`
indexes locally and skips the summary and lab staging.
The detail sheet shows where an imported document came from; backup and
restore carry both fields; Delete All Data clears the ledger.

Reading a stored document (suggest, summary, extract, index, chat,
reindex), scanning a lab report and turning medication text into a
schedule now answer under documentAi, labsOcr and medicationExtract. The
operator's master switch and the new reading-documents switch stop the
work and the egress; a module off for the record, a delegate inside
somebody else's record, and a missing receipt refuse with the capability
envelope. Existing no-provider codes keep their status.
The document pick and the labs pick re-check the capability for the
provider they picked, immediately before anything is sent, so a job
enqueued before a switch flipped finds no provider and falls back to the
provider-free text layer. Consent follows the document rule for all
three: any provider that leaves the machine needs an ai_extraction or
ai_full receipt, answered for the provider actually picked.
The fenced Coach chat and attachments answer under coach and documentAi.
Uploads are always stored and indexed; the background summary is only
enqueued while documentAi is open. The capability probes report the
capability beside the provider answer and keep a read offered when only
the receipt is missing. medications/extract keeps its 503 for no provider
and adds ai.provider.none, and its budget refusal gains the
coach.budget.exceeded code.
CLAUDE.md forbids planning shorthand in committed artefacts, and this branch
introduced 74 lines of it across source, tests, a schema field and two
migrations. Someone reading the migration SQL in a year has no way to resolve a
wave letter or a round number, and a comment that points at something outside
the repository names no reason at all.
Three passes. A version followed by a parenthetical keeps the version and loses
the parenthetical, because the version says since when something holds. A
sentence that leaned on the vocabulary to carry its meaning is rewritten to
state the reason directly: the arrival reservation now says it was refused over
money the operator never spent, rather than naming the defect a wave existed to
remove. Three test titles carried the marker in the name itself and are renamed
to what they pin.
Comments only. No behaviour, no renames beyond those three titles.
The owner split left an operator-funded chain with no ceiling at all. Its arm
compared operator_tokens, and that counter returns to roughly zero on every
reconcile the user's own plan settled: on the 2026-09-11 evidence the shared
key answered 500 and codex served, so the counter never grew, every job
reservation was admitted forever, and a runaway client loop could write an
unbounded row. A pre-existing concurrency contract caught it from the other
side, two reservations that must not both pass one cap both passing.
reserveBudget now refuses when the owner's counter is over its cap OR the day's
mixed total is over the abuse ceiling, and a background surface gets its share
of that ceiling too, so background spend is bounded on the total and not only
under a counter the operator's key never fills. The surface is a required
argument, so the type checker enumerated every reservation site.
The hop guard learns the same lesson: an operator-funded fallback hop is now
rationed at the calling surface's ceiling rather than the full operator cap. A
job admitted under the job share could previously spend the whole 200 000 once
its chain fell back onto the shared key, which is the original defect reached
by the fallback path.
The job share applies only where the operator pays for the chain. Multiplying
whichever ceiling the chain resolved halved background generation for a
self-hoster on a local model, who costs the operator nothing.
Refusals now name the ceiling they hit and whose it was. A refusal used to emit
the day's mixed total and nothing else, which on an operator refusal is not the
counter that tripped.
`coach_usage` counted one number per (user, day). A turn served by the
user's own ChatGPT plan after the operator's shared key answered 500 was
therefore charged to the operator-cost cap, and the operator's chat was
locked out every morning by background work he pays for himself.
The ledger gains `operator_tokens`: the share of `total_tokens` served by
an operator-funded provider. `reserveBudget` books a reservation to the
owner of the chain's primary and `reconcileSpend` settles it against the
provider that actually served, both inside the same statements as the
total so concurrent requests can never see one counter without the other.
Every call site names its cost owner and its serving hop; the argument is
required, so a new surface cannot inherit the old blind accounting.
A content-index attempt that failed (raster failure, a scan with no
text layer, a provider error) recorded its reason only in the server's
observability stream. In the vault, hasContentIndex false looked
identical for a document nobody ever tried and one that failed three
times, and the detail sheet had nothing to say about either.
Apply the summaryState pattern to the index. Two additive columns on
InboundDocument (migration 0333) record when the last attempt finished
and why it produced no index, as a closed reason set: local-empty,
local-unsupported, decrypt-error, raster-failed, provider-error,
pdf-needs-anthropic, empty-transcription. The writer sits at the choke
point the auto job and the corpus backfill share, and in the manual
index route; a success clears the reason. The provider path's specific
failure now survives the local fallback, since "no text" is less
actionable than "the PDF would not render". rasterizePdf names its
failure class so a build that cannot rasterize at all is distinguished
from a PDF that would not render. New guard in both index paths: an
empty provider transcription never becomes a successful empty index.
The detail sheet renders the reason in plain words (muted, six
locales). The DTO and OpenAPI carry the two fields; the disaster
recovery backup and restore carry them verbatim like their summary
siblings.

Only Anthropic accepts a native PDF block; codex and other image-only-wire
providers dropped it. Add a bounded, best-effort server-side rasterizer that
renders a PDF's pages to JPEG images those providers read as ordinary image
input, so a scanned/image-only PDF is legible on the auto-read path.
- @napi-rs/canvas promoted to a direct dependency; its musl prebuilts + the
pdfjs loader pinned into the standalone trace (next.config.ts)
- rasterize-pdf.ts: lazy pdfjs import (keeps DOMMatrix out of the eager chunk),
first 10 pages, 1600px long edge, JPEG q80, never throws
- prepareVisionInput rasterizes a PDF for a non-Anthropic vision provider and
keeps the native PDF block for Anthropic; the document capability reports
PDFs readable via raster so the UI offers the read
The auto-index-on-upload job resolved over the cost-first app-wide chain
(codex priority 1) and gated with the chain-based consent check, so a
pure-codex chain could silently egress a freshly uploaded document to the
subscription backend on upload. Reconcile it onto resolveDocumentVisionProvider
(local-first, codex last) and govern external egress with the
documentsAutoAiRead opt-in: a local pick always runs (no egress); an external
pick runs only when the toggle is ON, otherwise the job stays strictly local.
This tightens the default and makes the opt-in path deliberate.
Index a document for content search automatically the moment it is stored,
instead of requiring a manual index action. A fire-and-forget per-document
job runs an AI-first decision tree: when a vision-capable provider is
configured and consented, transcribe the stored original (rich, handles
scanned PDFs and images), budget-reserved exactly like the interactive index
route; otherwise fall back to server-side text-layer extraction via pdf-parse
(no provider, no egress, milliseconds) so content search works at a baseline
even with no AI. Budget exhaustion, a provider that cannot read the file
(a text-layer PDF on a non-Anthropic account), and provider errors all fall
through to the free local path rather than leave a document unsearchable.
Both paths write the same blind, encrypted content index (AES-256-GCM text +
opaque HMAC token tags) — nothing readable at rest. The local path adds the
'local-pdf' / 'local-ocr' source values (free String column, no migration).
Server-side OCR for scanned images and scanned PDFs is left as a documented
seam. Pin pdf-parse + pdfjs-dist into the standalone trace so the wasm text
extractor ships in the runtime image.
