+Upload is the only stage that needs credentials, so this module is also the single
+place that knows an API key exists. It never returns, logs, or renders the secret:
+:func:`build_command` produces the real argument list for the uploader, and
+:func:`redact` produces the copy that is safe for the API, the browser, and the
+activity log. Both come from the same builder so the preview can never drift from
+the command that would actually run.
+
+Server reachability uses ``/api/server/ping`` through stdlib ``urllib`` — the app
+has no HTTP client dependency and this is one request.
+
+:func:`run_upload` is the only place the uploader is actually executed. It never
+uses a shell (the argument list goes straight to ``execve``, so no path or album
+name can be interpreted), streams the report to a file with a byte cap so a chatty
+or looping uploader cannot fill the disk, scrubs the API key out of anything the
+process echoes back, and polls a cancellation callback so a running upload can be
+stopped without killing the worker.

+"""immich-go report parsing (US05-03).
+
+The uploader's output is the only local evidence of what Immich did with each file,
+and its wording changes between releases (concept §15 "external integration
+risks"). So parsing is deliberately conservative:
+
+- **the parser is chosen by uploader version, not by guessing the format.** Each
+  supported version family maps to one adapter with a pinned line grammar. An
+  unrecognised version yields no adapter at all, which makes every item uncertain
+  rather than optimistically successful.
+- **an unmatched line is never success.** Lines the adapter does not recognise are
+  counted (``unparsed``) and kept as evidence; they never classify an item.
+- **evidence is bounded.** Each entry keeps a trimmed copy of the line that
+  classified it, and the number of entries is capped, so a looping uploader cannot
+  turn the report into unbounded database rows.
+
+Two grammars are supported. ``text-v1`` is the default human-readable log of the
+0.21/0.22 line, ``json-v1`` the structured log (``--log-type=json``) of 0.23/0.24.
+Both classify through one shared phrase table, so the vocabulary cannot drift
+between them:
+
+```text
+text-v1   INFO  uploaded /lib/rome/a.jpg
+          INFO  server has the same file /lib/rome/b.jpg
+          ERROR error uploading /lib/rome/e.jpg: connection reset
+          Uploaded 1, duplicates 1, errors 1
+
+json-v1   {"level":"INFO","msg":"uploaded","file":"/lib/rome/a.jpg"}
+          {"level":"INFO","msg":"report","counts":{"uploaded":1}}
+```
+
+Nothing here touches the database; :mod:`photo_pipeline.services.upload_reports`
+turns a parse result into durable per-item outcomes.

+  never mentions, a report from an unpinned uploader version, and a line the
+  grammar does not recognise all leave the item ``unknown``. Exit code 0 is
+  evidence the *process* ended well, never evidence that a particular file reached
+  Immich (concept §15 "wrong upload state").
+- **counts are reconciled, not trusted.** The uploader's own summary is stored
+  next to the totals derived from the items. A disagreement makes the batch
+  ``requires_verification`` even when every line parsed.
+- **reprocessing is idempotent.** Outcomes are keyed by ``(batch_id, asset_id)``
+  and rewritten in place, so parsing the same report again — after a restart, or
+  because the operator asked — converges on the same rows and the same counts.
+
+The batch's own ``state`` still describes the process (US05-02's contract);
+``outcome_state`` describes the evidence. Turning ``requires_verification`` into
+verification, retry, and manual resolution is US05-04.

+"""UploadService — preflight for Immich upload (US05-01).
+
+Upload is the first stage that sends the library somewhere the app cannot take it
+back from, so nothing here uploads: preflight only *proves* a scope is safe and
+issues a token that a later start command must present (US05-02).
+
+What it proves (concept §8 "preflight"):
+
+- credentials are configured and the Immich server answers, without ever putting
+  the API key in a response, a preview, or a log line;
+- ``immich-go`` is installed and its version is recorded;
+- no rename is half-applied — the journal must not block library mutation;
+- every asset in scope is canonical, present, and decided ``sfw``/``nsfw`` with a
+  verified safety EXIF checkpoint;
+- every SFW asset also has a completed analysis EXIF checkpoint;
+- the bytes on disk right now still hash to what inventory recorded, so the album
+  preview describes the exact bytes that would be uploaded.
+
+Blocker codes are structured, never prose the UI has to parse:
+
+``no_library_root``, ``credentials_missing``, ``server_unreachable``,
+``immich_go_missing``, ``rename_pending``, ``unknown_album``, ``empty_scope``,
+``file_missing``, ``bytes_changed``, ``safety_undecided``, ``safety_deferred``,
+``safety_exif_unverified``, ``analysis_incomplete``, ``partial_scope``.
+
+**Partial scope is a blocker, not a default.** An album with any blocked asset is
+refused unless the caller passes the explicit ``allow_partial`` policy, which is
+itself part of the token — a token issued for a partial upload can never be
+replayed as a full one.
+
+The token is derived, not stored: it is a digest of the whole report (minus its
+timestamp), so any change that matters — a new decision, edited bytes, a different
+server, a resolved blocker, a different policy — produces a different token and the
+old one is stale by construction. No table, no invalidation bookkeeping.
