Brummel 1b6f4bde67 feat: Handle analyze retry with failure marker
When a previous analysis attempt fails and leaves a failure marker, the
retry mechanism now correctly identifies this state. It removes the
stale
input file, allowing the retry to proceed without a conflict error. This
ensures users can recover from analysis failures more gracefully.

Brummel 0848e9581f Fix gpt-oss-120b with reasoning effort
This commit adjusts the configuration for the `gpt-oss-120b` model to
run in plain-text mode. This is necessary because when
`reasoning_effort` is set to "medium", the reasoning tokens combined
with schema-constrained decoding can exhaust the `max_completion_tokens`
budget, leading to an empty content response.

The change restores the previous behavior where `gpt-oss-120b` was
configured without `response_format` or `top_p`, ensuring the request
body sent to Ionos remains byte-identical to the pre-multi-backend
state. This prevents regressions and maintains stability for existing
production workflows.

Brummel 3243823b40 Add Llama 3.1 405B specific LLM parameters
Configure Llama 3.1 405B with specific temperature, top_p, and a format
instruction. This addresses issues with infinite repetition and empty
document generation observed with this model. The format instruction is
added as a separate system message to avoid modifying the core medical
prompt.

Brummel a2cde9406e fix: skip already-failed inputs in analyze recovery scan
`recovery::enqueue_pending_for_user` previously enqueued any case with
`analysis_input.json` and no `document.md`, ignoring the failure marker
that `auto_trigger::evaluate_case` already honours. A timed-out LLM
call (e.g. Llama 3.1 405B at ~20 tok/s with default 4096 max_tokens)
left the input in place, the next case-list reload re-enqueued it, and
the worker hung another full timeout window — starving fresh user
clicks behind a failed retry loop.

Recovery now mirrors the same skip: if a marker exists whose
`last_recording_mtime` matches the input's, treat it as "already
tried, do not retry until input changes". Fresh recordings bump the
mtime and recovery picks the case back up.

Brummel 23ef84d9d8 feat: multi-backend LLM layer with per-request choice on case page
Replace the single [llm] block in settings.toml with a curated catalog
of LLM "backends" (provider + model + sampling params + system prompt)
in server/src/analyze/backend.rs. Two backends ship initially:
gpt_oss_120b (default, reasoning_effort=medium) and llama_3_1_405b
(uses response_format: json_schema to sidestep the <|eot_id|> leak).

The case page now renders one submit button per available backend; the
clicked button's name=backend value rides through AnalysisInput.backend_id
to the worker, which looks it up via find_backend() with default fallback.
A submitted unknown backend id is rejected as 400. .analysis_failed.json
records the failed backend and the failure banner surfaces its label.

The API key now comes from IONOS_API_KEY (env), not settings.toml; the
[llm] section is read into a discarded field so old configs still load.
Backends without a satisfied requires_api_key are filtered from the UI
(any_backend_available()). Three end-to-end tests that mocked the LLM
endpoint via settings.llm.url are #[ignore]'d with a clear note — they
need per-test backend injection (Arc<Vec<LlmBackend>> through the worker)
before they can be re-enabled.

Brummel cbb072d0cc feat: Show LLM failure banner and retry button
When an LLM analysis fails, a `.analysis_failed.json` marker is created.
If no document exists yet and the auto-trigger is blocked by this
marker,
the case page must display a banner. This banner provides the failure
reason and a button to retry the analysis, ensuring users are not left
in a dead-end state.

The `read_failure_marker` function is made public to allow the web layer
to access this failure information. The `CasePageTemplate` is updated to
include `analysis_failed` data, which conditionally renders the new
`.failure-banner` HTML.

This change prevents cases from becoming unrecoverable due to transient
LLM errors.
2026-05-03 13:53:55 +02:00
Brummel c5535c0848 Add reasoning_effort to chat request
Introduce a new field `reasoning_effort` to the `ChatRequest` struct.
This field, set to "medium" by default, allows tuning LLM reasoning
depth to balance hallucination risk against latency and token cost. This
setting is specifically for Ionos' GPT-OSS reasoning models and is
ignored by other OpenAI-compatible models.

Brummel dc7ba40433 Refactor system prompt for medical assistant
The system prompt for the medical assistant has been refactored to
improve clarity and precision. Key changes include:

- Enhanced instructions on handling transcribed errors, emphasizing
  verbatim transcription and the use of `==...==` for uncertain parts.
- More explicit guidance on the formatting of dosage schemes, including
  the conversion of numerical representations to hyphenated formats
  (e.g., "1-0-2").
- Introduction of specific examples for common medical abbreviations and
  terms, such as "CDAI > 450", "per os", and "iv.".
- A new critical rule to enclose any output not part of the transcript
  in `[...]`.
- The addition of "Ileus" to `medical_terms.txt` and "Adalimumab",
  "Infliximab" to `vocabulary.txt`.

Brummel 330e84e473 Consolidate analysis prompt and extend domain vocabulary
Sandbox-validated against case c414cf52 (3 runs each, fair pre+post-LLM
gazetteer pipeline): the new prompt eliminates two hallucination classes
the prior version produced — unmarked "Hypotonie" when the dictation said
"Hypertonie" (0/3 vs 2/3) and inventing units like "35 ng/l" for values
without unit (0/3 vs 2/3) — while keeping Latin terms (Punctum Maximum
etc.) intact in 3/3 runs vs 2/3.

Block layout reorganized so each rule appears exactly once: AUFGABE /
QUELLE / KORREKTUR-POLITIK / TREUE / CHRONOLOGIE / DOSIERUNGSSCHEMA /
MARKIERUNGEN. The removed "AKTIVE KORREKTUR (nicht durchreichen)" hammer
block is no longer load-bearing because the gazetteer's pre-LLM pass now
catches the typical drug-name typos before the LLM sees them.

Vocabulary additions (single-token, alphabetical, ≥5 chars):
- vocabulary.txt: Enoxaparin (was missing — Inoxaparin→Enoxaparin is a
  recurrent ASR error and the prior pipeline relied on the LLM alone)
- medical_terms.txt (new file, picked up by the dir-glob loader):
  Holosystolikum, Klappenvitien, Koronarbaum, Pumpfunktion

Brummel d092c1621c Tighten consolidation prompt: fidelity clause, conflict-resolution
Sandbox-iteration unter experiments/case_c414cf52 (3 Runs je Variante,
gpt-oss-120b @ Ionos, temperature=0). v2_treue gewinnt gegen Baseline
und v1_treue auf folgenden Achsen ohne Curve-Fitting im Prompt:

- Active drug-name correction (Inoxaparin→Enoxaparin, Thorazemit→
  Torasemid, AFREF→HFrEF) durchgesetzt: 3/3 statt 0/3
- Schema 1-0-0 / 1-0-1 zuverlässiger: 3/3 statt 2/3
- Troponin-T fehlende Einheit als ==35== markiert (vorher unkommuniziert)
- Hypo/Hyper-Verlaufsgeschichte aus widersprüchlichen Aufnahmen
  unterdrückt: 0/3 (war 1/3 in v1_treue)
- Anatomische Lokalisationen, "adipöser Ernährungszustand" und
  Diktat-Reihenfolge bleiben treu (vorher selten aber gelegentlich
  weggelassen oder umsortiert)
- Format als Fließtext explizit, Pseudo-Headings reduziert

Strukturell offen (kein Prompt-Fix möglich): "Holosystolikum" aus
Whispers Halbwortruine "Tolikum", "Koronarbund"-Halluzination aus
"Corona-Baum" — beides braucht Gazetteer-Erweiterung oder
Tokenizer-Refactor, separate PRs.

Umstellung auf Rust-Raw-String macht die Prompt-Datei deutlich
lesbarer (keine \n-Escapes, keine \"-Escapes mehr).

Brummel c15590f3e0 Refactor transcript file handling to use JSON metadata
This commit changes the way transcriptions are stored and accessed.
Instead of using plain text files (`.transcript.txt`), transcriptions
will now be part of a JSON metadata file (`<stem>.json`). This allows
for richer metadata to be stored alongside the transcript, such as
duration, and provides a more robust mechanism for tracking
transcription states.

The changes include:
- Updating documentation and code to reflect the new `.json` file
  extension.
- Modifying file handling logic to read and write JSON metadata.
- Adjusting tests to accommodate the new file format.
2026-04-27 13:08:36 +02:00
Brummel 66b3b7e4c8 Refactor recording metadata to JSON sidecar
Replaces the `.transcript.txt` sidecar with a structured `.json` file
for recording metadata. This change consolidates transcript text,
duration, and other potential metadata into a single, extensible JSON
object.

This also refactors the `TranscriptState` enum to better represent the
on-disk state (absence of file means pending) and the in-memory
representation. The `Transcript` enum now specifically models the
terminal outcomes of the transcriber (`Silent` or `Content`).

The commit includes updates to documentation, data structures, path
handling, and various tests to align with the new metadata format.

Brummel a510c20e75 refactor(server): plumb Arc<Settings> through workers and routes
Config sheds its 14 Bucket-B fields (retention, whisper, ollama, llm) and
gains a sibling Arc<Settings> in AppState, loaded from settings.toml at
startup via Settings::load_or_default. Workers (transcribe, analyze,
recovery, auto_trigger) and routes (health, bulk, case_actions,
user_web) take settings as a separate parameter or State<> extractor;
Config::llm_configured moves to Settings::llm_configured.

TestConfig::build_pair() returns (Arc<Config>, Arc<Settings>); the new
create_router_with_settings / create_router_and_session_store_with_settings
helpers wire both into integration tests that exercise LLM/Whisper/Ollama.
The legacy single-Arc create_router falls back to Settings::default()
so the 17 non-LLM tests stay untouched.

Verified: cargo build clean, clippy --all-targets clean, 318 tests pass.
2026-04-27 11:48:41 +02:00
Brummel 813fb896ff refactor: consolidate bulk actions, URL assembly, and case-artefact filenames
Pulls three pattern groups into shared helpers so a rename or wire-format
tweak edits one file instead of 10+:

- BulkAction enum in doctate-common replaces the "close"/"analyze"/"reset"
  string literals that were duplicated between the bulk handler and 3
  attack/CSRF test files. FromStr preserves the exact "Unbekannte Aktion"
  error shape; the handler match is now exhaustive over the enum.
- join_url helper in doctate-common absorbs 7 identical
  trim_end_matches+format! call sites across client-core, client-desktop,
  server/transcribe (ollama, whisper), and server/analyze (llm).
- server/tests/common/artefacts.rs re-exports ONELINER_FILENAME
  (doctate-common), DOCUMENT_FILE + ANALYSIS_INPUT_FILE
  (doctate-server::analyze), and CLOSE_MARKER (doctate-server::paths) so
  test files reference the canonical name instead of inlining literals.

Also lifts client-desktop local duplication:
- paths.rs: project_path helper collapses 4 identical ProjectDirs chains
- main.rs: or_die helper replaces 4 eprintln!+exit(1) blocks
- app.rs: named RecordingContext struct replaces (Uuid, String) tuple
  at 3 sites around the ffmpeg-flush finalization path

Verification: 397 tests pass (baseline was 389; +8 for new unit tests on
BulkAction and join_url), 0 failed, 4 ignored (unchanged). clippy clean.

Brummel 4531f85b13 fix: settle silent-only cases to Empty oneliner state
Introduce `TranscriptState { Pending, Silent, Content }` in
doctate-common as the canonical three-way state of a recording's
`.transcript.txt` sidecar. Previously each call-site projected the
raw `Option<String>` / `.exists()` onto its own 2-state view and the
projections disagreed: the UI treated a 0-byte silent transcript like
`Content` while the oneliner worker treated it like `Pending`,
leaving silent-only cases stuck on "generiere Titel …" forever with
no persisted oneliner.json.

`update_oneliner` now settles a silent-only case to
`OnelinerState::Empty` when no `Content` transcript exists and no
recording is still `Pending`, so the UI resolves to "unbenannt" and
recovery treats it as terminal.

Single reader: `paths::read_transcript_state`. All call-sites
(scan_recordings, compute_oneliner_display, has_pending_recordings,
all_transcripts_joined, read_recordings, enqueue_pending_for_user,
scan_m4as, cases_needing_oneliner_in, case_recordings.html) go
through the same typed abstraction and must handle `Silent` via
exhaustive match.

Regression tests:
- silent_case_empty_test: heal path settles silent-only case to
  Empty without calling Ollama
- case_page_silent_only_shows_empty_not_generating: UI renders
  "unbenannt", not "generiere Titel …"

Brummel 9410d6daaa refactor: rename soft-delete marker from .deleted to .closed
Internal rename: DELETE_MARKER -> CLOSE_MARKER, DeleteMarker ->
CloseMarker, is_deleted -> is_closed. The batch UUID is dropped;
undo now groups cases by their exact closed_at timestamp, which
bulk-close writes identically across its selection while per-case
close writes a unique stamp.

Behavior unchanged. No migration (project is pre-production);
legacy .deleted files in tmpdata were removed manually.

Brummel 70425939b2 feat: Add auto-trigger for LLM analysis
Introduces a new module `auto_trigger` responsible for opportunistically
initiating LLM analysis jobs. This mechanism scans case directories for
new or updated recordings and transcripts, automatically creating and
queuing analysis jobs when appropriate.

Key components:
- `evaluate_case`: Pure function to determine if a case is ready for
  analysis based on recording status, transcriptions, document
  modification times, and existing job/failure markers.
- `try_enqueue`: Orchestrates the analysis job creation and queuing
  process if `evaluate_case` returns `AutoDecision::Enqueue`.
- `try_enqueue_all_for_user`: Iterates through all user cases to trigger
  `try_enqueue` for eligible ones.
- `write_failure_marker`/`remove_failure_marker`: Handles persistent
  recording of analysis failures and their cleanup.

This feature aims to reduce manual intervention by automatically
analyzing new or changed case data.

Brummel 1d702e2d85 Add event bus for live UI updates
Introduces a system for broadcasting real-time events to the web UI.
This enables features like automatic page reloads when case data changes
in the background, improving the user experience by keeping the UI
synchronized with the backend.

Key components:
- `events` module: Contains the `CaseEventKind` enum, `CaseEvent`
  struct, and `EventSender` type for managing the broadcast channel.
- SSE endpoint (`/web/events`): Streams events to connected browsers.
- Client-side JavaScript: Listens for events and triggers debounced page
  reloads.
- Integration points: Workers and route handlers now emit events when
  relevant state changes occur.

Brummel 421fbb3e46 Update system prompt for medical assistant
The system prompt for the medical assistant LLM has been updated to
improve clarity and explicitly state the desired formatting for
corrections and uncertainties. This includes:

- Consolidating similar correction examples.
- Specifying that only "==text==" annotations are allowed for
  corrections and uncertainties.
- Explicitly disallowing other annotation formats like "(unsicher)" or
  "[TODO]".

Brummel 13e1950050 Refactor gazetteer to replace post-AI
The gazetteer has been refactored to act as a post-AI normalization
filter. Previously, it was used to annotate LLM input with potential
corrections from a vocabulary. This approach was ineffective because
LLMs often override such hints.

The new approach applies the gazetteer *after* the LLM has generated its
output. This allows for deterministic correction of known terminology,
including fixing LLM output drift (e.g., anglicized drug names).

Key changes:
- `annotate` function renamed to `replace`.
- The output format changes from `Canonical [?original]` to simply the
  `Canonical` form.
- The gazetteer now operates on the final LLM output before persistence,
  ensuring consistency.
- Tests have been updated to reflect this new behavior, focusing on the
  final output rather than the LLM request payload.
2026-04-16 20:21:07 +02:00
Brummel bacbcb90fe Refactor gazetteer annotation format
The gazetteer now annotates text with `Canonical [?original]`. This
prioritizes the corrected term for the LLM while keeping the original
transcription as a fallback.

This change aligns the gazetteer's annotation strategy with the LLM's
prompt, which expects corrections to be marked for review. Previously,
the format was `original [?Canonical]`, which could lead to the LLM
using the potentially incorrect original term.

Brummel e16cb988ed feat: Add gazetteer annotation to user prompt
This commit introduces functionality to annotate the user prompt with
potential proper name corrections from a gazetteer. The LLM will then
use these annotations to improve the accuracy of transcriptions,
especially for medical terms and names.

The `SYSTEM_PROMPT` has also been updated to inform the LLM about these
new annotations and how to handle them.

Brummel 5717b8f718 Add gazetteer to analyze worker

the directory is missing or unreadable, the worker will start without
proper-name correction capabilities.
2026-04-16 17:27:09 +02:00
Brummel 07f9d9ed26 Add markdown rendering for LLM output
This commit introduces a new module `analyze::render` to handle the
rendering of Markdown content produced by the LLM into safe HTML.

The LLM output now includes a custom `==text==` highlighting convention
to indicate sections that require doctor review due to potential
transcription errors or incomplete information. This highlighting is
converted into `<mark>` tags in the final HTML.

To ensure security, all LLM-generated Markdown is first HTML-escaped.
This prevents any malicious HTML or script injection from being executed
in the browser. Only the custom `<mark>` tags are preserved as
functional HTML elements.

The process is as follows:
1.  The raw Markdown from the LLM is processed.
2.  All HTML special characters (`<`, `>`, `&`, `"`, `'`) are escaped.
3.  The `==text==` highlights are replaced with `<mark>text</mark>`.
4.  The resulting string is parsed as Markdown by `pulldown-cmark`.
5.  The parsed Markdown is converted to HTML, which is then safe to
    inject into the Askama template using the `|safe` filter.

The `Cargo.toml` and `Cargo.lock` files have been updated to include the
`pulldown-cmark` dependency. The `document.html` template has been
modified to use a `div` with the class `doc-content` instead of a `pre`
tag, allowing the rendered HTML to be displayed correctly. The
`handle_document_view` function now calls the new `md_to_html` rendering
function.

Brummel 44ed5e8333 Refactor ollama transcription prompts
The system prompt for the transcription Ollama LLM has been updated to
improve robustness and clarity, especially for handling empty or
non-medical transcripts.

The prompt has been refactored to:
- Use English for instructions to improve robustness with smaller LLMs.
- Clearly define the behavior for empty or non-medical transcripts,
  requiring an empty string response.
- Reduce the maximum character limit from 120 to 60 to better fit
  smartwatch displays.
- Ensure the output is German, adhering to the original language
  requirement for the output.
- Add an explicit instruction to correct transcription errors in the
  input dictation for the consolidation LLM.

Brummel 3a656bd2a9 Refactor LLM API key handling for Ollama
The LLM client now conditionally adds the `Authorization` header only

endpoints. A new integration test verifies the functionality against an
Ollama-compatible endpoint without an API key.

Brummel 8c6b2eeaa4 Refactor analysis file names
The versioning of analysis input and document files
(`analysis_input_v{N}.json`, `document_v{N}.md`) has been removed. All
analysis inputs will now use `analysis_input.json` and generated
documents will use `document.md`.

This simplifies file management, as there's no longer a need to track
and manage multiple versions of these files within a case directory. The
analysis worker will now overwrite the existing `document.md` if it
exists, ensuring that the latest analysis result is always present. The
`version` field has also been removed from `AnalyzeJob` and
`AnalysisInput`.
2026-04-16 01:56:55 +02:00
Brummel 990d166617 Refactor case listing and silent recording handling
The case listing on the "My Cases" page is now grouped by local date,
with labels for "Heute", "Gestern", or the ISO date. This improves
readability and organization.

Additionally, the handling of silent recordings has been refined.
Previously, the absence of usable recordings would result in an error.
Now, the analysis worker gracefully handles this by writing a stub
document and skipping the LLM call. This prevents unnecessary errors and
provides a clearer status for silent cases.

The `dictate.sh` script has been updated to simplify the case directory
lookup logic. Instead of iterating through `open` and `done`
subdirectories, it now directly checks for the case ID and ensures it's
not marked as deleted. This simplifies the script and improves
efficiency.

The `server/Cargo.toml` and `server/Cargo.lock` have been updated to
include the `num_threads` dependency and enable additional features for
the `time` crate, which are necessary for proper local time zone
handling.

Brummel 2f62f11563 Refactor busy flags and worker guards
The `WorkerBusy` type was previously a single `Arc<AtomicBool>` shared
between the analyze and transcribe workers. This commit refactors this
to:

- Introduce `AnalyzeBusy` and `TranscribeBusy` newtype wrappers around
  `WorkerBusy` to distinguish between the two flags. This allows
  `axum::extract::State` to target them individually.
- Move the `BusyGuard` RAII guard into `src/lib.rs` and make it generic
  to work with any `WorkerBusy` instance.
- Update the `main.rs`, `worker.rs`, and `routes/user_web.rs` files to
  use the new types and guards, ensuring correct state management for
  both pipelines.
- Enhance the transcription recovery scan
  (`transcribe::recovery::scan_and_enqueue`) to iterate over user
  directories and call `enqueue_pending_for_user` for each, making it
  more robust and aligned with the per-user self-healing mechanism.
- Add a check for `transcribe_busy` in the `case_detail.html` template
  to correctly display "Transkription läuft…" only when the transcribe
  worker is actually active.
2026-04-16 00:32:45 +02:00
Brummel 9072d7a833 Refactor analyze recovery and worker busy status
The analyze recovery scan has been refactored to iterate through user
directories and enqueue pending analysis jobs more efficiently. The
`WorkerBusy` status has been introduced as an `Arc<AtomicBool>` to track
whether the analyze worker is currently processing a job.

This `WorkerBusy` flag is used in the `analyze::worker::run` function
and managed by a `BusyGuard` RAII struct, ensuring the flag is correctly
set and unset even in case of panics.

The `handle_my_cases` and `handle_case_detail` handlers in `user_web.rs`
now utilize the `WorkerBusy` flag to accurately display the "analyzing"
status and to trigger a self-heal of orphaned analysis inputs when the
worker is idle.

Additionally, the `WorkerBusy` type is now exported from
`server/src/lib.rs` to be accessible by other modules. The test cases
have been updated to include the `WorkerBusy` parameter when spawning
the analyze worker.

Brummel 0b63d8ff56 Feat: Add bulk actions for case analysis and deletion
Introduces a new `/web/cases/bulk` endpoint to handle multiple case
actions simultaneously.

This change adds the following:
- A new `bulk` module for handling bulk operations.
- The `handle_bulk_action` function in `bulk.rs` to dispatch to specific
  actions.
- `bulk_analyze` and `bulk_delete` functions to process the actions.
- Updates `Cargo.toml` and `Cargo.lock` to include necessary
  dependencies: `form_urlencoded`, `serde_core`, `serde_html_form`, and
  `serde_path_to_error`.
- Modified `axum-extra` features to include `form`.
- Adds checks for deleted cases in `collect_pending` for both analysis
  and transcription recovery.
- Renames and modifies `handle_close_case` to `handle_analyze_case` in
  `case_actions.rs` to better reflect its functionality.
- Adds a new `handle_delete_case` and `handle_undo_delete` to
  `case_actions.rs`.
- Updates `my_cases.html` and `case_detail.html` to support bulk
  actions, including checkboxes, a bulk action bar, and an "Undo last
  delete" feature.
- Modifies `handle_audio` and `scan_cases` in `web.rs` to respect delete
  markers.
- Updates `analyze_test.rs` with new request builders for analyze and
  delete actions.

Brummel 11eb645f3f Refactor: Simplify case directory structure
The distinction between `open/` and `done/` directories for cases has
been removed.
All cases for a user now reside directly under the user's directory
(e.g., `<data_path>/<slug>/<case_id>/`).

This simplifies path management and eliminates redundant directory
traversals.

Key changes include:
- Removed `open/` and `done/` subdirectories in path resolution.
- Introduced a `paths::case_dir` function as a single source of truth
  for case directory layout.
- Updated various modules (`recovery`, `auth`, `routes`, `transcribe`,
  `tests`) to use the new path structure.
- Adjusted templates to reflect the simplified case status
  representation.

Brummel e2a05a108a feat: Add analyze module for LLM integration
This commit introduces the `analyze` module, which orchestrates
communication with Large Language Models (LLMs) for text summarization
and analysis.

Key components include:
- `llm.rs`: Contains the `LlmError` enum and the `chat_once` function
  for interacting with OpenAI-compatible LLM APIs.
- `prompt.rs`: Defines the system prompt and logic for rendering user
  content from analysis inputs.
- `recovery.rs`: Implements logic to scan for and re-enqueue pending
