Daniel	0163d40811	fix: every presentation takes a theme, not only the ones the model designed ... "Change template" answered "no slide layout" for 28 of the 41 presentations in production: the theme lived only inside the deck JSON, and a presentation whose deck reply failed twice and fell back to markdown slides had nowhere to keep one. The theme is a column now, written at generation and by the picker, and the markdown slide builder carries it to the same renderer field a designed deck uses. A deck's own theme field is kept in step. Articles are the only thing refused — they have no slides. A deck reply that fails to parse is logged with its first 240 characters, so the next "the reply was not a deck" can be read rather than guessed at.

Daniel	1c5e218382	fix: a retried starter-question batch gets other snippets, and the pool's model is documented ... The same snippets sent DeepSeek into the same 26,000-character reasoning spiral three times running, each ending in an empty reply at the token ceiling. A retry now rotates the snippets. Production sets clinical_assistant.prompt_model to gpt-4.1-mini, a model that does not think about a list of questions; the setting is now documented with why.

Daniel	d517a3fdf6	fix: an empty model reply is logged with its finish reason, and a pool batch that gets one is retried once ... Two batches in five came back as a 200 with an empty message — nothing in the gateway log, nothing in ours. callLiteLLM now says when that happens (finish reason, completion tokens, whether the tokens went into reasoning), and the starter-question build tries such a batch once more instead of writing the category off.

Daniel	a528986a2d	fix: a starter-question batch no longer dies when the reply is cut off ... Cases are three to four times the length of headings, and 30 of them did not fit the 2,600-token ceiling: the JSON was cut mid-list, failed to parse, and whole categories came back with nothing kept. The ceiling is 7,000, batches are 20, and a reply that is still cut off yields every question that finished rather than none. Each batch logs what it offered.

Daniel	75f5486beb	fix: an array of route paths is several operations, pages are none, and the prompt-pool build says what it did ... app.get(['/', '/index.html', '/assistant']) reached the OpenAPI generator as one route whose path was the array, joined with commas; the e2e reachability check then probed "/,/index.html,/assistant" and found a 404. Each path is now its own route, and routes outside /api/ are left out: the document describes what a client calls, and a client does not call index.html. The starter-question pool logs when a build starts, what each category kept, and how long it took, so a build that produces nothing can be traced.

Daniel	8c6126b112	feat: starter questions are cases with a decision, and the pool rebuilds itself when the prompt changes ... The pool read like a chapter index — "What red flags in a child's headache history warrant investigation?", "Which clinical scores are useful for asthma?". The prompt now asks for what a clinician types with a patient in front of them: a one-line vignette with an age and at least one number, then the one decision to make now. The filter enforces it: a number is required, textbook openers are refused, and the length cap makes room for a case. A pool carries the prompt version it was built with. One from an older version is served as before and rebuilt in the background, so a prompt change reaches the screen without anyone pressing Regenerate.

Daniel	e58aa1b996	refactor: sign-in codes and registration invitations leave; the SSO has both ... Sign-in is email → code at sso.pedshub.com, and new accounts come from an invitation link minted there, so the app's own code emails and invite codes recorded a path nobody can take. Gone: the login-code routes and their rate limiters, the invite admin API and card, the invite field on the register form, the "email me a code / use my password" choice on the sign-in screen (an email now leads straight to the password), both utility modules, and the invite-only setting. A migration drops login_codes and registration_invites.

Daniel	fa9970458f	fix: the export's last table column wraps again, and citations-off strips every marker form ... The export styles pinned the last column of every table to one unbreakable line (width:1%; white-space:nowrap) — right for a numbers column, wrong for a two-column clinical table whose second column is the whole finding: the table grew to the width of its longest sentence and iOS then inflated the text in those cells, so the "Finding" column read in a bigger font than the "Feature" column. The pin goes, and the sheet opts out of text inflation. With citations switched off the answer is still grounded in the retrieved sources; only the markers are removed. The stripper now also removes the escaped \[1, 2\] form and [src] placeholders, which used to survive as text.

Daniel	07161c6fa8	feat: speech models have a roster; each brings its voices, users choose across all of them ... Discover lists speech models with the voices each accepts and a + Add that puts the model on tts.roster. The Roster card lists every model with a voice picker, Test, Make default and Remove. Test on any row (or a discovered model not yet added) fills the test panel's voice list with that model's voices, so Orpheus and Kokoro can be heard one voice at a time before either is chosen. The default is a pair — PUT /config/tts/default sets tts.model and tts.voice together and refuses a voice the model does not accept, naming the ones it does. The generic setter no longer takes tts.model/tts.voice one at a time, which is how a Kokoro voice got paired with Orpheus. A default that leaves the roster stops being the default. Users pick from the voices of every roster model, grouped by model in Settings; the stored value is "model|voice" so read-aloud sends the voice to the model that accepts it. A bare voice saved before there was a roster is read as a voice of the default model. chooseTTS is the one place the pair is decided, shared by read-aloud, the admin test and the settings options.

Daniel	e376f69502	fix: each TTS model offers only the voices it will accept ... "These settings don't work" — picking a model and testing with a voice returned 500 every time. The gateway said why, once asked directly: voice must be one of the following voices: [autumn diana hannah austin daniel troy] The screen was listing twelve Orpheus voices and six Kokoro ones in a single flat list with no indication of which model would accept which, because LITELLM_TTS_VOICES — written for one model — was treated as a list that applied to all of them, and the Orpheus lists were pushed in beside it. Choosing Orpheus and testing it with a Kokoro voice is not a configuration; it is an error, and it was the default outcome. LiteLLM cannot supply this. /model/info reports mode audio_speech for all four models and carries no voice field for any of them. So the mapping lives here, keyed by family so the gateway alias and the upstream id resolve to one list, and every list was taken from the provider rather than from documentation: Groq Orpheus English autumn diana hannah austin daniel troy (stated by Groq) Groq Orpheus Arabic abdullah fahad sultan lulwa noura aisha (stated by Groq) Fish s2.1-pro alloy (alloy returns audio; the rest 400) Kokoro sherpa/kokoro:* from LITELLM_TTS_VOICES (the gateway's own list) The environment still wins for the model it was written for, so the local gateway's voices can change without a code change — but it answers for that model only. A model with no list at all is offered nothing rather than another model's voices, and a voice known to belong to a different family is refused. There were two copies of this knowledge before: getLiteLLMTTSVoicesForModel branched by family and fell through to the env list for any model it did not recognise — which is how Fish came to be offered six Kokoro voices. One table now. Also in this commit: citation renumbering skips fenced code, inline code and math, so arr[2][1] in a code block is never rewritten. Renumbering at render time was tried and reverted — it also has to skip HTML attributes, and every such region is another regex branch. It stays at the answer boundary, and the saved-chat boundary is next.

Daniel	3e8972348a	feat: a revoked invitation can be deleted ... Revoked codes had a Revoke button and nothing else — the row stayed on the list for good. The reasoning was that revoke stops a live code and leaves the row behind as a record, which is right about revoke and wrong about what comes after: a revoked code is already dead. It cannot be redeemed by anyone, so keeping it only fills the list. The rule that matters is unchanged, and it is the only one that ever mattered: a code that could still be redeemed is never deletable. Deleting one takes it off the list without taking it out of anybody's inbox — the holder keeps something that looks valid, it quietly stops working, and nothing is left to say who had it. Revoke is what stops such a code; deleting it afterwards is the second half of the same thought, and it was missing. Also removed a note that had been wrong since codes became copyable: "The code is shown once, here. Only its hash is stored, so it cannot be read again afterwards." Both sentences stopped being true when the cipher was added so an invitation could be handed to somebody later than the moment it was made.

Daniel	0287fd091b	feat: a key per search provider, and the sign-in code email looks like our mail ... Two things, both about not making someone redo work. One key per provider. There was a single websearch.api_key shared by all of them, so trying a different provider meant pasting a new key over the working one and pasting the old one back to return — and the keys are not interchangeable, so a wrong pairing fails as an authentication error that reads like a dead provider. Each now has its own slot. The old shared key is still read as a fallback: whatever was configured before this is the right key for whichever provider was selected at the time. The sign-in code email went out raw, while every other message this app sends goes through emailWrapper — so the one mail a person receives while locked out was the one that looked least like it came from us. It now uses the same wrapper, and the body is built around the thing the reader actually needs: the code, alone, large, monospaced so a 0 cannot be read as an O, in a box of its own. It also names the address it signs into. A code arriving at a shared mailbox, or to someone with two accounts, is otherwise a number with no indication of what it opens — and that line is the one thing that lets a person notice a sign-in they did not start. The address is escaped; it is the only part of that mail that did not come from us.

Daniel	1242b01286	feat: Exa as a search source; the speech buttons say what they do ... Two unrelated small things in the admin. Exa searches by meaning rather than keywords, which suits a clinical question asked as a question — the shape the assistant actually sends. It is also the only provider that returns the page text in the same call, and the snippet is the part the model reads, so asking for it there saves a second fetch per result. type is 'auto' rather than 'neural': pinning neural makes it worse at the keyword-shaped queries the other four handle well. One adapter, one dropdown entry, no other change — the route already validated against webSearch.PROVIDERS, so the backend accepted it the moment the list grew. A test now walks both lists in both directions: a provider the server takes but the admin never offers is unreachable, and one the admin offers but the server rejects is a setting that cannot be saved. The speech and transcription buttons said "Set". Directly beneath them is a Roster card headed "What has been added", and Set is the one thing that does not add anything — there is a single voice and a single model, and choosing one replaces the last. They now say "Make default", and the note says plainly that nothing joins a list.

Daniel	c14fa25c3f	fix: the image settings card can save again; Learning Hub is out of the admin ... "Not all of it was saved: Workflow not found" on every press of Save availability. The card sent image settings for three workflows, and the server has only had two since Learning Hub was removed — the DB constraint allows clinical_assistant and my_resources and nothing else. One rejection failed the whole save, so the two settings that were valid looked unsaved as well. The frontend was the only place that still believed in it. Also gone: the learning_hub.image_behavior prompt, its Learning prompts section in the admin — which held that one prompt and nothing else — and the theme's card tints, which never applied. While there: My Resources had a Model dropdown labelled "set per request", permanently disabled and permanently empty. A control that can never do anything reads as broken rather than as not applicable, so it is now a sentence saying where the model is actually chosen. Its fallbacks stay — those apply to whichever model the request picked.

Daniel	3a40ff9b6d	fix: the theme reaches the renderer, so changing it changes the deck ... Picking a theme on a saved resource did nothing. The picker saved the choice, the route wrote deck.theme, and the renderer knew how to apply it — the theme was lost in between. attachFigures, the step that puts drawn figures back onto slides, rebuilds the deck as a fresh object: var out = { title, subtitle, date, slides }; A fresh object keeps only the fields it names, and theme was not one. So every export rendered in the default palette, whatever the picker said. Rendering the same deck under clinical-blue, teaching-amber and high-contrast produced three byte-identical files; it now produces three different ones, and they look different. Silent, because nothing downstream could tell the difference between a deck with no theme and a deck whose theme had been dropped — both mean "use the default", which is also the right behaviour for an unknown id. Known and not fixed here: the two tinted cards on a compare slide are hardcoded blue and amber rather than taken from the theme, so those stay the same colour under every palette. The headings, accent, rules and bullets do change. That is a gap in the theme definition, not in this path.

Daniel	993442f98a	feat: the API describes itself, at /api/openapi.json ... docs/api-reference.md was hand-written, and by the time anyone checked it was documenting twenty-three endpoints that answer 404 while missing others that exist. That is what hand-written reference material does: it is correct on the day it is written and silently wrong afterwards. A second hand-written document, in YAML this time, would rot the same way. So paths, methods and mount points are read from the Express router stack at request time. They cannot disagree with the app, because they are the app: 186 paths, 215 operations, and — checked — no /learning endpoints, which is what the prose version went on claiming for weeks after that feature was deleted. What introspection cannot know is what an endpoint is *for*. That half lives in src/utils/openapiRoutes.js, keyed by "METHOD /path", and it is the half that rots, so it is the half that is enforced: a Playwright spec fetches the live document and fails when the number of operations without a summary rises above 199 — the debt as measured today. A ratchet, not a target. Adding an endpoint pushes the count over and fails the build; describing one lowers the number. The failure lists the operations by name, so it says what to write. Whether an operation is public is stated per route rather than inferred from middleware. Guessing wrong there is worse in both directions: calling a public endpoint protected hides a hole, and the reverse invites a bug report. The contract spec lives in e2e rather than the unit suite because it needs the whole app mounted, and requiring server.js from node:test pulls in the database pool and hangs the run — that has happened here before. Also: e2e now runs in CI on dev, gated by a shell check inside the step rather than a job-level "if", which this Forgejo dispatches anyway and then kills with "Early termination".

Daniel	38b8fd584a	fix: the sign-in code email no longer mentions the password ... "Your password still works as usual" is not reassurance for everyone who gets this mail. An account created through an invite has no password at all, and one signing in with a code may never use theirs — for them the sentence raises a question rather than settling one. What the paragraph is for is saying that ignoring the mail is safe, and it says that without the second sentence.

Daniel	5f738fbe30	feat: a theme is shown by a sample deck you download, not a picture ... A picture of one slide answers a narrower question than the one a theme picker is asked. What a person wants to know is what a deck will look like in this theme — all of it, at the size it will be shown, with the fonts substituted the way they will be. One rendered slide showed one layout, in content someone then read instead of looking at. So: a sample deck per theme. Every layout the renderer can draw — title, bullets with a sub-point, both two-column forms, table, callout, figure, full-slide figure, section divider, a custom slide with shapes, an arrow and a chart, and a references slide — with filler text throughout. Download it, open it, see the theme. The text is deliberately meaningless. Clinical content in a specimen invites you to read it, and then you are judging the teaching rather than the type; that is what the old croup slide got wrong. No engine. The previous preview needed a Gotenberg round trip and a pdftoppm to produce a PNG, cached on disk because of what it cost, and could fail in ways a missing picture cannot explain. python-pptx builds the file in ~330ms and PowerPoint draws it. The link is a plain anchor, so it is there whether or not anything on the server is well. The figure placeholder rides the same path a generated figure does — attachFigures downgrades a figure slide with no picture to bullets and an image slide to a section, so without it the sample would silently stop showing those two layouts. Verified: all five themes build, 11 slides, the chart is a real chart and the placeholder embeds as real media.

Daniel	a505244b97	refactor: remove the embedding settings, whose only consumer is gone ... Embeddings existed here for Learning Hub semantic search — the card said so itself. Learning Hub was removed, and nothing took its place: the clinical corpus is embedded by the indexing service, not by this app. What was left was a settings page that configured a model, tested it, reported its dimensions, and fed nothing. src/utils/embeddings.js had exactly one importer, src/routes/adminConfig .js, which used it for the three routes this deletes. Outside those, the only mentions of embedding in the server were a comment and a settings prefix. Gone: the module, its three admin routes, the dimension probe, the Discover & test kind and its two panels, the admin.js block behind them, the embeddings. prefix from both the writable-settings allowlist and the lockdown list (it can no longer be written at all, so locking it says nothing), and docs/embeddings-setup.md, which documented Learning Hub search end to end. 'embedding' stays in NON_CHAT_MODES — that is the filter keeping embedding models out of the chat-model list, and the gateway still serves them. Docs still describe nine /api/learning endpoints that no longer exist, left from the Learning Hub removal. Not touched here; that is its own subject.

Daniel	a7132c218e	feat: a ciphertext now only decrypts in the row it was written for ... enc1 said what a value was but not where it belonged. The blob in one user's nextcloud_token would decrypt perfectly if copied onto another user's row, and that account's exports would then go into someone else's storage. Nothing about the ciphertext objected. Adds enc2, which binds a context string — 'users:nextcloud_token:41' — as AES-GCM additional authenticated data. The auth tag covers it, so a moved ciphertext fails to open rather than opening somewhere wrong. The context is authenticated, not encrypted: it is not a secret, it is a claim about location. enc1 is still read, unchanged and forever — every existing row is enc1. Bound rows are distinguishable (isBound), so the Nextcloud token is rebound in place the next time it is successfully used, the same way a legacy plaintext one was already upgraded. That gate moved from isEncrypted to isBound; isEncrypted is true for enc1, so it would have skipped exactly the rows that need rebinding. Bound so far: Nextcloud app passwords, and invite codes — which bind to their own code_hash, since unlike the row id that exists at INSERT time. Decrypting an invite moved into list(), so the cipher and the hash that opens it no longer leave the module together. Mutation-tested: dropping the AAD, dropping the guard, gating on isEncrypted, or dropping a context at a call site each fail a test.

Daniel	24c8d71b7e	feat: send a resource to your own Nextcloud, as the rendered file ... A .pptx landing in someone's own storage is worth having; a markdown blob is not, and it is not what they would have downloaded. So this renders through exactly the path the download uses — stored deck, its figures, the chosen theme — and PUTs the bytes. The file never travels through the browser. Offered only when a Nextcloud is connected: an action that always fails is worse than one that is not offered. An article offers Word, a deck PowerPoint, and asking for slides from an article is refused with the reason. Putting a file in Nextcloud now lives in src/utils/nextcloudFiles.js. Two callers want it and neither should grow its own copy of the WebDAV dance — make the dated folder a segment at a time, PUT, migrate a legacy plaintext token — because it reaches into storage that is not ours and a second slightly different copy is how the two drift. It also replaces a route importing another route. Also: a model that leaves the roster now leaves every list that names it. clinical_assistant.allowed_models and the image roster are advisory copies of the roster, and a stale id there was invisible until someone asked a clinical question and the request failed at the gateway. Removing or disabling a model prunes it; clearing the roster clears them. Re-enabling deliberately does not re-allow it — that is a separate decision.

Daniel	025290d64a	feat: retire Learning Hub ... My Resources generates better slides than Learning Hub ever did — a typed deck the model fills in, rendered by python-pptx with fit-to-slide text, figures, a vision review and themes, against Learning Hub's markdown-through-pandoc — and the articles and quizzes now live in the quiz app. Keeping a second, weaker generator and a whole CMS beside it was not earning its maintenance. Removed: three routers, the Learning Hub and Content Manager tabs, their components and frontend modules, the five database tables, the WebDAV browser, the content embedding column and its vector index. Content was exported first — every article as markdown plus a full SQL dump of all five tables — to ops-backups/learning-hub-export-*. That export is the restore path; the migration's down() can recreate the shape but never the rows, and says so. Two things this simplifies rather than merely deletes: generated_image_links existed only to record which published content an image appeared in, and it was the sole reason a generated image could be read by someone who did not make it. Images are now owner-only — the visibility rule is one WHERE clause instead of a join across two tables and a published flag. embeddings.js keeps the model discovery the admin panel uses and loses searchSimilar and generateContentEmbedding, which queried a table that no longer exists. Kept deliberately: Nextcloud connect, disconnect and export, which are how a generated note reaches a real filesystem and have nothing to do with Learning Hub; learningRetrieval, which despite its name is the clinical corpus search My Resources depends on; and the pandoc reference deck, still the fallback when the python renderer fails, moved from assets/learning to assets/deck now that the old name misleads. Tests: four Learning-Hub-only files removed, and the individual cases inside shared files that asserted its behaviour. Where a test used a Learning endpoint only as a convenient example — the account-boundary token test, the policy matrix — it now uses one that still exists, so the property it proves is unchanged.

Daniel	bf4f895f2c	fix: article uploads are 10 MB, type-checked both ways, and sniffed ... The ceiling was 100 MB per file with ten files allowed at once, and every file is held whole in memory to be parsed — so the old limit let a single request ask for a gigabyte of heap. A source article that size is not a thing anyone uploads here. Now 10 MB, defined once and used by both the multer limit and the post-upload check. The filter accepted `allowed mime OR allowed extension`, so naming a file .pdf was enough on its own, whatever it declared — and the extension is chosen by whoever uploads. Both are required now. Neither of those sees any bytes: multer filters on the headers, before the file has arrived. verifySources() runs once the buffer exists and refuses a file whose contents are not what its type claims, using the same helper as documents, S3 uploads and assistant attachments. It runs before extraction, because an extractor handed a malformed file is where the damage would happen. The CMS screen said 100 MB and listed four of the ten accepted formats; it now says what the server actually does.

Daniel	bd8e413bc7	fix: an assistant attachment must be the image type it claims to be ... The MIME type was taken on trust here. Anything at all could be posted as image/png: it passed the size and base64 checks, was stored in the saved chat, and was handed to a provider as a data URI. Documents and S3 uploads have always been sniffed by fileType.js; this was the one upload path that was not. Now sniffed with the same helper, so there is one idea of what a PNG looks like. A PHP payload, a shell script, an ELF or PE binary, a zip, or a real PDF labelled image/png are all refused with a message that says what is wrong. What this does not claim: bytes hidden after a valid PNG header still make a valid PNG, and no sniffer can promise otherwise. The protection is that the file is never executed and never served as anything but an image. Existing fixtures used buffers of 0x07 as stand-in images, which are correctly refused now. They carry real file headers instead — a fixture should be the thing it claims to be, exactly like a real upload. Also adds the deck theme system: five palettes in assets/deck-themes.json, render_pptx.py rebinding its palette from the theme rather than hardcoding it, the theme carried on the deck and validated against the same catalogue the renderer reads, a picker on the generate form, and PUT /my-resources/:id/theme to re-skin a stored deck with no model call.

Daniel	ff2b2bc9d3	chore: Kitten and Supertonic retired; Kokoro is the local voice ... Both were removed from the gateway in favour of Kokoro, so the app's curated voice lists for them went too. Kokoro's own check no longer has to exclude them — it names its own voices and the list is open, so it accepts anything that is not another family's voice. Voices stay curated per family rather than discovered. Models are discovered from /model/info; voices are not, because no TTS provider exposes its voice list consistently, and a list guessed from a model id is how a picker ends up offering a voice the provider rejects. Tests that pinned the retired voices now pin the families that remain.

Daniel	fce05a2749	fix: the active library view is unmistakable, and a leading question cannot mislead the vision model ... Documents and Images were two buttons of the same weight, which reads as two buttons rather than as a current view and an alternative. The active one now carries the surface, the weight and a hairline — keyed off aria-selected, so the visible highlight and what a screen reader announces cannot disagree. The look_at_image question is written by a model that has not seen the image, from what the user said, so it can presume something that is not there — "describe this rash" about a photograph of a drug chart. Answering the presumption would send it back as fact. The seeing model is now told the question may assume something absent, and to say so first and describe what is actually there.

Daniel	1f06a19007	feat: a text-only model can ask a model that can see; and the image regex is gone ... **The regex is gone.** The route ran a pattern over the user's message and enqueued an image from the answer text when the model had not called the tool. It was a compatibility path for models without tool calling and it did more harm than good: it decided in English only, it could not see the conversation, and "image summary" fell through it while reading as an obvious image request to the model itself — which was measured, not assumed. A second and worse decision-maker sitting behind the first. Whether a message deserves a picture is now the model's call, made from the tool description, which is the only place it ever belonged. **Lending eyes.** The same shape, for a different capability. When someone attaches a photograph and the chat model cannot accept image input, the attachment was either refused by the provider or silently dropped — an answer about a picture nobody had looked at, which is worse than a refusal. The chat model is now offered look_at_image beside the image tool and decides when to use it. The attachment goes to clinical_assistant.vision_model, whose description comes back as a tool result, and the chat model answers in its own voice with its own sources. Only the seeing is delegated; the clinical reasoning stays with the model an administrator chose. The seeing model is told to report and not to diagnose, because it has a picture and no context and an opinion from it would carry weight it has not earned. Delegation triggers only on an explicit supports_vision: false from the gateway. An unknown is left alone — most of a roster reports nothing, and treating silence as blindness would route good models through a detour. The capability lookup moved to its own module, is cached for five minutes because it runs on exactly the requests that are already slowest, and is never inferred from the model id. liteLLMBaseUrl moved from the admin route to litellm.js, where the other gateway helpers live. The new setting is guarded like the slide reviewer: a model the gateway calls text-only cannot be saved as the one that looks at images.

Daniel	03621752e8	feat: image fallback chains for every workflow, and a library worth looking at ... **Fallbacks.** One image model meant a refusal, a rate limit or a model the gateway had since dropped ended as a missing picture. Every workflow now tries its model, then each fallback in order, stopping at the first that produces an image. Primary plus two, capped: each hop is a paid request, and a chain long enough to need a cap is long enough to surprise someone. My Resources previously had no fallback at all — only the Clinical Assistant did, and only one. That is backwards: a missing figure is most visible in a deck, where it leaves a hole in a slide. The retry rule is now a classifier that says *why*, rather than a boolean. Transient faults, a 404 for a model the gateway does not have, and a content refusal all move to the next model — a refusal because policy is a vendor decision, not a fact about the request. 401/403 stop immediately (one gateway, one set of credentials, the next model fails identically), as do 413 and any other 4xx, which are malformed everywhere. Refusals are recognised from the message: no provider sends a machine-readable reason and the status varies. Each hop re-leases the job, so a chain cannot outlive its claim and let a second worker repeat the same paid work, and the row records the model actually being paid for so a picture made by the third model is not attributed to the first. The old singular `fallback_image_model` is still read, so an existing configuration keeps working without anyone re-entering it. **Library.** Documents/Images tabs in My Resources, with a real grid: fixed aspect tiles so the rows line up whatever shape the pictures are, a source badge on the picture, two-line prompt, hover lift, shimmer skeletons while thumbnails land, and a lightbox that closes on Escape or the backdrop and restores focus. Actions are hidden on hover only behind `@media (hover:hover)` — hiding delete behind :hover would put it out of reach on touch and keyboard. Downloads go through privateImageBlob rather than a bare `<a download href>`: a mobile client's session is a bearer token an anchor cannot send, and these assets are served no-store on purpose. The gallery lives in My Resources only. Assistant images appear in it, which was the point; the assistant page does not grow a gallery of its own, and a test asserts no assistant module lists the endpoint.

Daniel	259b4858be	feat: an image library — every picture this account has made ... A figure outlives the deck it was drawn for: the deck gets replaced, the diagram is still good. Until now a generated image could only be seen in the resource it was made for, and there was no way to find one again or to delete it. Library → Images is a grid of every finished image the account owns, across all three workflows, newest first. GET /api/generated-images is scoped by owner_id in the statement rather than filtered after, returns only finished jobs — an unfinished one is a broken frame in a gallery — and pages by keyset, because a gallery that grows while you scroll repeats or skips rows under OFFSET. Most of this already existed. Thumbnails were already rendered at 256 and 640 by sharp and already served by ?w=, with their own checksum so the client's tamper check passes on a derived copy; hydrateImage already handles auth, the account boundary and caching. The tiles ask for the 256px preview, so thirty of them cost a few kB each rather than thirty full-size downloads, and the prompt is decrypted for the caption because it is the only human-readable label an image has. Deleting needed new work. The storage interface had no remove at all, so a delete that dropped the row would have left the object and both previews in the bucket — paid for, and still readable by anything with credentials. Storage now removes all three keys, and the bytes go before the row: a row pointing at a missing object is a broken image in a gallery, while an object without its row is only wasted space, and unreachable storage refuses the delete outright rather than reporting a success that left the picture behind. THUMB_WIDTHS now has one definition, in generatedImageStorage. Two copies drift, and the drift that matters is a width that gets written and never deleted.

Daniel	83206e907c	fix: a second deck reused the first deck's pictures ... The image job key was the request-body hash plus the figure's position — slide index for a deck, reply index for a document. Two generations from the same form produce the same body hash, so figure 4 of the second generation collided with figure 4 of the first on the unique (owner, workflow, idempotency_key). The constraint handed back the existing job, and the new deck displayed the old deck's artwork. The decks are not even the same length, so the reused picture could land on a slide about something else entirely. Keyed on what is being drawn now: the body hash stays, so submitting the identical request twice still dedupes rather than billing twice, and a hash of the prompt (plus layout and shape) is what makes two different pictures two different jobs. Same fix in deckBuild and resourceImages. Also split fileLog out of logger. logger requires the database at module load, so importing it to record a diagnostic pulls in a connection pool — wrong on its own terms, and it hung the whole test suite when imageTool started logging its refusals: a unit test that never touches a database inherited an open pool handle and never exited. logger.file now delegates to fileLog, so there is still one implementation of where a line goes and how it is redacted. With that in place, every image-tool refusal is recorded durably. There are five of them, they want five different fixes, and until now none of them left any trace once the container was replaced. Verified against a mutation: restoring the index-based key fails two of the four collision tests.

Daniel	94f320f140	fix: an empty answer from the model was the one failure never caught ... The Clinical Assistant answered "image summary" with a zero-length string, saved that as the turn, and drew it as an empty bubble. No error was raised, nothing was logged, and the empty turn stayed in the conversation history where it degrades every answer after it. Confirmed by decrypting the saved chat: the final assistant turn is content length 0. The cause is one line. finalizeAssistantAnswer only regenerates an answer that shouldRegenerateTruncatedAnswer flags, and that function opens with `if (!answer) return false` — there is no dangling conjunction to detect in a zero-length string, so empty was classified as "not truncated" and returned as a result. Every other failure mode had a path; this one had none. An empty answer is now asked for once more — a model returning nothing is usually transient — and if it comes back empty again it raises 502 `empty_answer`, which both callers already turn into a visible error. Whitespace counts as empty, and so does an answer that strips to nothing. Without a callAI to retry with it still raises rather than returning empty. Verified against a mutation: removing the new branch fails five of the six tests. This is separate from the image question in the same request. No image job was created, because "image summary" does not match the text fallback pattern — which requires a verb (create/generate/draw/…) before the noun — and the model did not call the tool. That is left alone for now: the request is genuinely ambiguous, and guessing at it is how an assistant starts making pictures nobody asked for.

Daniel	e244ee5240	feat: modifying a deck can see it ... The model editing a deck could not see it, which made most of what people actually ask for unanswerable: "that slide is too crowded", "the diagram is in the wrong place", "this one looks empty" are facts about the rendered page, not about the JSON. When a vision model is configured, modifying now renders the current deck — with its figures, unlike the review pass, which runs while they are still being drawn — and hands the model one image per slide alongside the JSON. Same pipeline as review, reused rather than reimplemented: pptx, Gotenberg, PDF, pdftoppm, capped at MAX_SLIDES. The vision model then does the editing, which is a second and separately measured benefit. On a real 20-slide deck, ds-deepseek-v4-flash returned the deck unchanged for "make it better" — the echo reported yesterday — while openrouter-gemini-3.8-flash applied it. So the stronger model fixes the echo even without sight. A model the author picks explicitly still wins over both. The result is rendered and reviewed again. Generation-only was the old rule, on the reasoning that refining is a text edit; it is not. The edit is made against how the deck looked before it, so a slide that gains two bullets only overflows once it is rendered again. The reviewer may reposition but is held to the same words, so a verification pass cannot quietly undo what was just asked for. Whether an instruction achieved anything is judged on the model's edit, before the reviewer runs, or a reviewer nudging a slide into two columns would mask an instruction that did nothing. Sight is an upgrade, never a dependency: no vision model, Gotenberg down, a render that fails — each falls through to editing blind, and a test covers each of those paths. Verified against two mutations: keeping the text model when images are attached, and dropping the verification pass, each fail exactly one test.

Daniel	5614a436be	fix: a deck asked for a figure and never got one — three causes, one symptom ... "Include a diagram" produced decks with no picture. Three separate faults, each hiding the next, found by generating the same deck after fixing each one. First, deck generation ran on the default 4000-token budget. A deck's JSON is several times the size of the prose it holds, so a long deck came back truncated, failed to parse, and fell back to markdown — which has no way to request a figure, so the model described one instead and the slide rendered a literal "![Placeholder: Flow diagram ...]" as its first bullet. Deck generation now gets room, and the fallback says how the reply failed: empty, cut short at N characters, or not a deck. Second, the figure request sat inside the layout vocabulary, one line among forty, and the model passed over it. It goes last now, after the author's own instructions — the same placement lesson the image tool taught earlier. Third, and the one that actually mattered: image_prompt is only read on the figure and image types, so an image_prompt on a bullets slide was dropped in silence. The instruction said "add image_prompt to N slides" without saying which types carry one. It now names them, and a misplaced request is honoured rather than discarded — a slide with words becomes a figure, one without becomes a full-slide image. Image markup is also stripped wherever text enters a slide, on both paths: a described figure is not a figure, and a bullet of raw markdown is worse than no bullet. Verified end to end after: the same request produced a deck with one figure, the job completed, and the exported pptx carries one embedded image across 21 slides.

Daniel	2c3fbbcf37	fix: decks were falling back to markdown, so no figure could ever be requested ... A deck's JSON is several times the size of the prose it holds, and generation used the default 4000-token budget — raised for refine and for slide review, but never here. A sixteen-slide deck ran past it, came back truncated, failed to parse, and fell back to markdown. Markdown has no way to ask for a figure, so the model described one instead and the slide rendered a literal "![Placeholder: Flow diagram — "Neonate with rash" → ...]" as its first bullet, above the steps it was meant to illustrate. That is why no generated deck was arriving with an image. Deck generation now gets room for a deck. The fallback also says how the reply failed — empty, cut short at N characters, or simply not a deck — because those want different fixes and "not usable" covered all three. Image markup is stripped wherever text enters a slide, on both the deck and markdown paths, since a described figure is not a figure and a bullet of raw markdown is worse than no bullet. The model is also told plainly: if a figure is wanted say so with image_prompt, and if that is not on offer, write the slide without one rather than describing the picture you would have drawn. Separately, the Documentation list showed ARCHITECTURE, CLINICAL_ASSISTANT, DEVELOPMENT, MODULE_CONVENTIONS and SCALING shouting in caps with underscores intact: the label builder replaced hyphens but not underscores, and uppercased the first letter of each word rather than normalising the case, so a SHOUTING_FILENAME stayed shouting. It now reads "Clinical Assistant", keeps acronyms as acronyms (AI, API, OpenID, LiteLLM) and leaves joining words lower.

Daniel	012346528c	fix: generation stopped working whenever the slide reviewer was switched off ... savedFigureIds was declared inside the review branch, so with no reviewer configured — the default, and what everyone is running — it was undefined by the time the INSERT stringified it. JSON.stringify(undefined) is not a string, the column is NOT NULL, and every generation failed with "Generation failed". `var` is function-scoped, so nothing complained until the database did. This is the second bug of exactly this shape in this file, so the test asserts position rather than presence: the value must be declared before both the review and the insert read it. Found by the logging added in the same change, which is the other half of this commit. Every modification now says what it did: [my-resources] refine id=29 path=deck outcome=applied 13→14 slides changed=yes [my-resources] refine id=37 path=markdown outcome=applied 2635→3018 chars changed=yes CHANGED=no is warn-level and deliberately shouty, because that is the failure worth catching: the response says success either way, the row updates, and the download is identical — which is exactly how the deck bug went unnoticed. A refusal logs its reason. ped_ai_resource_refine_total{path,outcome} counts the same thing over time, so "did that modification do anything" is answerable without watching logs live. Verified across every path rather than the one that was broken: a deck presentation modified and exported to both pptx and docx carries the change; a legacy presentation with no stored deck still takes the markdown path and carries it; an article generates, modifies and exports; and a presentation generates with the reviewer off.

Daniel	4f8e686907	feat: record what a deck wanted and could not have ... The shape vocabulary is deliberately small, which leaves the question of what to add next. Rather than guess, it now records demand. Two signals, because a model asks both ways. It can say so outright — {"kind":"unsupported","need":"a SmartArt cycle of four stages"}, which draws nothing and is told about in the same file that validates it — or it can reach for a kind, chart type or slide type that does not exist, which is the more common way of asking and just as much of a signal. Both produce a log line naming what was wanted and the topic it came up on, and increment ped_ai_deck_vocabulary_gap_total{wanted}, so it can be counted over time in Grafana rather than noticed once and forgotten. Deduplicated per generation and capped at twelve: a model that asks for a hundred things it cannot have should not write a hundred log lines. It can never fail a generation — it is a note to whoever decides what to build next. This is also the answer to whether to run model-authored code in a sandbox instead. The log will say whether the gap is real. Some of it is not closeable by any sandbox, being python-pptx's own ceiling — no SmartArt, no animations or transitions, limited chart types — and a sandbox would only let a model write code against the same library and hit the same wall. Documented in docs/my-resources.md, which the in-app Docs tab serves directly.

Daniel	af2e09c1de	feat: a slide can be drawn from primitives when the named layouts have no word for it ... The nine layouts are a fixed vocabulary and a good default, but "lay the three severity levels out left to right with arrows between them" had no expression in them at all. A "custom" slide now carries a list of shapes: positioned text, eight autoshape families, lines, images, tables, and native PowerPoint charts — column, bar, line, pie, doughnut. Coordinates are percentages of the slide rather than EMU, because a model reasons about "the left half" and not about 12192000. Shapes draw in array order, so a later one sits on top. The model never emits Python. It names shapes and the renderer draws them: running model-authored code to lay out a slide would be an enormous amount of trust to buy a feature, on a server holding clinical data and secrets. Validation lives beside the text that teaches the vocabulary, in one file, so what the model is told about is exactly what is accepted. Kinds are an allowlist, colours must be six hex digits, coordinates are clamped inside the slide — a shape at x=95 w=30 is cut to the edge rather than drawn half off it — counts are capped, a pie is held to one series, and anything that cannot be understood is dropped. A custom slide that loses every shape becomes a plain one rather than a heading over an empty frame, and one bad shape is caught in the renderer so it cannot cost the slide it sits on. A figure on a custom slide is requested through an image shape, drawn by the same path as any other, and attached by job id. Word renders a custom slide as its words in reading order with its tables and figures — lossy, and better than dropping the slide. Verified live end to end: asked to "lay the three severity levels out left to right as coloured boxes with arrows between them", the model produced [rect arrow rect arrow rect], chose green/amber/red itself, and the rendered slide was looked at. A column chart beside its commentary renders with real axes and gridlines.

Daniel	154b896d5b	feat: Word is built by python-docx from the same typed source as the deck ... Pandoc reads markdown, so every Word export had to flatten the resource to markdown first — and a deck flattened to markdown stops being one. A comparison became two headings and two lists, a callout became bold text, and a figure became nothing at all, because markdown has nowhere to put it. src/utils/docSpec.js reduces either source to the same blocks: a stored deck where there is one, the markdown where there is not. scripts/render_docx.py draws them. A comparison comes out as a labelled two-column table, a callout as a shaded box, a table as a real table, a figure embedded at its own aspect ratio with its caption, and speaker notes as muted indented text. The deck wins over the markdown beside it, because that markdown is a serialisation of the deck and reading it instead would be reading a lossy copy of what is right there. Word now carries the figures too. The export route skipped fetching them for docx, which was correct when pandoc could not place them and wrong the moment this could. Pandoc stays installed and stays the fallback: a plainer document beats a failed download. Both renderers now share one spawn helper. Verified end to end: a deck with two figures exported as a six-page Word document with both images embedded (537KB, two files in word/media), rendered to PDF and looked at — the comparison is a labelled table, the figure sits at its true aspect ratio, and the notes read as notes.

Daniel	9d307fd442	feat: a vision model looks at the rendered deck and fixes the layout ... The model that writes a deck never sees it. It cannot tell that slide four overflowed, that a nine-item list would read better in two columns, or that two labelled groups want to be a comparison — those are facts about the rendered page, not about the text. So each generated deck is now rendered to PDF through Gotenberg, rasterised to one image per slide with pdftoppm, and shown to a vision model. Off unless an administrator names a reviewer, in its own admin card because it is the one setting that spends money on every generation without a user having asked for anything. One pass, on generation only: a second pass costs as much as the first and fixes far less, and refining is a text edit. It returns a patch, not a deck. Asking for the corrected deck back put the reply in proportion to the deck rather than to the number of problems, and a fourteen-slide deck came back cut off mid-object at every output budget the provider would honour — measured twice before changing shape. The patch is better for a second reason. The reviewer names a slide and an action — two columns, one column, split after bullet N, compare with these two labels — and the server moves the text it already has. The words never pass through the model, so a review cannot reword, drop or invent a single bullet. That is a stronger guarantee than instructing it not to and checking afterwards. The check runs anyway, because a bug in applyChanges would be as bad as a model rewriting the words and worse for being trusted: body text must come out the same multiset, figures the same set, and a heading may only be reused or extended. A continuation heading is the reviewer's one piece of text and is replaced when it does not continue anything. Nothing here can fail a generation — no reviewer, an unreachable one, an unparseable reply, a deck too long to look at, or a patch that applies to nothing each return the deck that was written. Verified end to end against a deck with a deliberately overloaded slide: three slides rendered and sent, one change returned, ten bullets split into five and five under "Stepwise Management … (continued)", text intact. Left switched off; enable it under Admin. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Dv6sqaY6Vq3ChZHMem3cnU	2026-09-11 21:38:18 +02:00
Daniel	fa2e7523d6	docs: My Resources, sign-in codes, invitations, and what the image carries ... Nothing documented My Resources, the slide renderer, PubMed or web search, and the authentication doc predated both sign-in codes and registration invitations. docs/my-resources.md is new and covers the feature end to end: what a resource is, where its material comes from, why both searches run in the route rather than as tools the model never called, why keyword engines get the topic while retrieval gets the instruction too, how a presentation is designed as a deck rather than written as markdown, the separate multi-image path, and what the export pipeline is made of. docs/authentication.md gains sign-in codes — storage, lifetime, reuse, supersession, guessing, and that two-factor still applies — and registration invitations, including the exact condition that decides when a code may be deleted and why it is written to match the status the list displays. Both new rate limits are in the table, with a note that Express matches app.use paths on segment boundaries, so a new sign-in endpoint needs its own limiter or it has none at all. docs/deployment.md now says what the runtime image carries and why — pandoc for Word, python3 with apk-installed lxml and pillow for the slide renderer, python-pptx pinned, and that PDF conversion is not in the image at all but goes to Gotenberg, so Word and PowerPoint still work when it is down. docs/configuration.md picks up LOGIN_RATE_LIMIT_MAX, LOGIN_CODE_RATE_LIMIT_MAX and GOTENBERG_URL, none of which were listed. README gains a My Resources section and indexes the two new docs.

Daniel	b98ffc61c7	fix: expired invitations can be cleared too, revoked ones still cannot ... An expired code is as dead as a used one and just as accounted for, so it is now deletable. The rule the code enforces is the one that matters: a code that could still be redeemed is never deleted, because that takes it off the list without taking it out of anybody's inbox — the holder keeps something that looks valid, it quietly stops working, and nothing is left to say who had it. One condition, shared by the single delete and the bulk clear: (used_at IS NOT NULL OR (revoked_at IS NULL AND expires_at <= NOW())) Written that way rather than as "used OR past its date" because the second form also catches a revoked code whose date has since passed — a row the list still labels revoked and offers no delete on, so the button and the query would have disagreed about the same row. Revoked codes keep their rows. Revoking records a decision somebody took, and a handful of them is not the clutter a pile of expired codes is. Verified against the live database across every state: active refused, used deleted, expired deleted, revoked refused, and revoked-with-a-past-date refused rather than slipping through as expired.

Daniel	7b084c7edf	fix: an invitation can only be deleted once it has been used ... The delete button was offered on every invitation regardless of state, and the query behind it deleted any row it was given. Deleting an unused code takes it off the list without taking it out of anybody's inbox: the person still holds something that looks like a valid invitation, it silently stops working, and there is no longer a record of who it went to or why. Revoke is what stops a live code — it leaves the row behind, marked. So the delete is now for spent codes only, in three places rather than one: the query carries AND used_at IS NOT NULL, the route answers 409 with the reason instead of pretending the row is missing, and the button is rendered only on a used row. A "Clear N used" control alongside, since the complaint was clutter and clearing them one at a time is not much of an answer. Same rule — nothing unused or revoked is touched — and it confirms first, because it is still a delete. The bulk route is declared before /invites/:id, or Express reads "used" as an id. Verified against the live database: deleting an unused invitation is refused and the row survives, deleting a used one works, the bulk clear removes only used ones, and the unused probe row was still there afterwards.

Daniel	22683f3584	feat: sign in with a code emailed to you, offered beside the password ... The sign-in screen asks for an email first, then offers both ways in together: a six-digit code sent to that address, or the password. Beside rather than instead — a code depends on mail being delivered and a password does not, so neither may be the only route. "Use a different email" goes back a step, and creating an account stays where it was. What keeps it from being a second, weaker front door: - Only a bcrypt hash is stored, so a code read out of the database is not a working credential. - Ten minutes, single use, marked used before the session is issued so a replay cannot race it, and requesting a new one deletes the old. - Five wrong guesses burn it. Six digits is a million possibilities, which is plenty against a person and nothing against a script with unlimited tries. - Requesting a code answers identically whether or not the address exists, and every verify failure returns one message. A sign-in screen that says "no such account" is a way of finding out who has one. - Two-factor still applies: a code proves you can read the mailbox, which is one factor, and an account that asked for a second still wants it. - Its own rate limits, tighter for requesting than for attempting, because requesting sends mail to someone else's address. These had to be separate limiters: Express matches app.use paths on segment boundaries, so /api/auth/login does not cover /api/auth/login-code — checked against a real router rather than assumed. Two bugs found while building it, both mine: authFetch keeps an allowlist of endpoints callable with no verified owner and rejects everything else before it is sent. The new endpoints were not on it, so the request never left the browser and surfaced as "Connection error". reveal() hid elements by appending 'hidden' to className and showed them with a non-global replace, so hiding twice left two copies and showing stripped one. The "use a different email" link never reappeared. It uses classList now, which is idempotent. Verified against the running server: correct code signs in, the same code again is refused, a superseded code is refused, five wrong guesses burn it, an expired one is refused, and the stored value is a hash. In the browser: requesting a code advances the screen, a wrong code is refused without losing the screen, and the password route still signs in. Not yet demonstrated: a correct code typed into the browser. The harness keeps racing the one-live-code rule — the page's own request supersedes whatever code the test holds, and with SMTP off the delivered one cannot be read. The same request reaches the server on the wrong-code path, and the endpoint itself is verified, but that last step is untested end to end.

Daniel	087f717f55	feat: the model designs the deck instead of writing markdown for a parser to guess at ... Markdown could express about five of the things the renderer can draw, so the model had no way to say "put this figure beside these three bullets" or "make this a comparison with two labelled columns" — my parser inferred a layout from the shape of a list, and inferring is what made every deck look the same. A presentation is now described as a deck: the model returns JSON naming a layout per slide and the prompt it wants each figure drawn from. Four layouts were added to the renderer for it — two tinted labelled columns for a comparison, a callout card for a red flag or a dose, a figure beside its bullets, and a full-slide figure. Articles stay markdown, which is what prose wants. Markdown is still produced, serialised from the deck, so Word export and text editing keep working and the stored artifact stays readable by a person. The deck is stored alongside it because that serialisation is lossy by design: round-tripping through markdown would throw away exactly the layout choices this was built to capture. A resource made before this, or an article forced into slides, still renders by inferring from its markdown. Nothing here can cost more than the thing that went wrong. A reply that is not a deck falls back to asking for markdown rather than saving the model's apology; a malformed slide degrades to bullets rather than throwing; a comparison with one column is not a comparison; a figure that cannot be queued leaves a slide of text rather than an empty frame; and JSON wrapped in fences or a covering sentence is read rather than refused. Verified live on "croup versus epiglottitis": the model chose section, bullets, table, compare, figure, callout and image layouts across thirteen slides, and the exported deck was rendered to PDF, rasterised and looked at — the comparison renders as two tinted cards, the red flag as a callout, and the figure sits beside its bullets.

Daniel	73ce4049d4	feat: decks are built with python-pptx instead of pandoc, and carry their figures ... Pandoc's pptx writer was the ceiling on how good a generated deck could be, and the model on top made no difference to it. It maps markdown onto a handful of reference layouts with no per-slide layout, no positioning and no control over how large an image is drawn, which is why every deck came out as bullets on a template — and why autofit had to be injected into its emitted OOXML by hand afterwards, because LibreOffice ignores the autofit pandoc leaves off. scripts/render_pptx.py draws the deck and src/utils/slideSpec.js decides what each slide is. Markdown stays the stored artifact, so "change slide 4" is still a text edit and Word export is untouched — pandoc still writes docx, where its output is good. What that buys, all of it visible in a rendered deck rather than argued for: - 16:9, not pandoc's 4:3. - A pipe table becomes a real table with a header band and banded rows, not eight lines of text with pipes in them. - A list longer than seven items becomes two columns instead of a wall of text. - Text is measured and sized to fit before the file is written, so nothing depends on a renderer honouring autofit. - Wrapped lines hang under the text instead of running back to the margin, which is the clearest single tell that a deck was generated. - An image is drawn at its own aspect ratio, centred, with a caption. Figures now reach the deck at all, which they never did. They were queued and shown on the page, but nothing recorded that they belonged to the resource, so an export could not include them: user_resources.image_ids holds them, a modification adds to that list rather than replacing it, and export fetches the finished ones to a scratch directory. They are spread through the deck rather than appended, because ending on three unexplained pictures is worse than showing each near its material, and a References slide stays last. If the renderer fails for any reason, pandoc still produces a deck — a plainer deck beats a failed download. Verified end to end: a seven-slide request with three figures exported as a 13-page deck; the slides were rendered to PDF, rasterised and looked at. All three formats still download.

Daniel	1ad72b134b	feat: a resource can have several illustrations, on its own path ... My Resources used imageTool.dispatch, which permits exactly one image per request — "Only one image tool invocation is permitted per request". That is the right rule for a chat reply and the wrong one for a twelve-slide deck where the author asked for three figures. Rather than relax a limit the clinical assistant and the Learning Hub also depend on, this adds a separate dispatcher for this feature. Same queue, same storage, same my_resources workflow, same asset endpoint — only the number of figures differs, bounded at six because each one is a paid request. "Use 3 diagrams" in the instructions is read as the number it is, and the illustration option now says several are possible rather than promising one. Three things had to be got right, each found by measuring rather than assuming: The illustration guidance has to be the last thing in the prompt. Placed before the output rules it lost — with the tool offered and the paragraph present, the model returned 3297 characters of markdown and zero tool calls, while the same tool and wording in a shorter prompt produced three calls. Even last, it loses to a prompt carrying thirty library excerpts: deterministically, with the library off "use 3 diagrams" made three calls and with the library on it made none and wrote a longer deck instead. So when the author names a number the call is required rather than merely offered. With no number named the choice stays the model's. And a model that has just made three tool calls tends to sign off instead of writing: "I'll create the presentation and the three teaching diagrams." was returned as the resource — 61 characters — because only a completely empty body counted as missing. A body with no title block and no heading is not a Pandoc document whatever its length, and if the continuation is no better than the first attempt, whichever actually reads like a resource is kept. Verified end to end with the library on: generate produced three figures and an eight-slide deck; modify added two more figures and a ninth slide. The figures were fetched and looked at — labelled airway anatomy, and a croup/epiglottitis/ bacterial tracheitis comparison.

Daniel	055a86bbb1	feat: My Resources says what it is, offers its sources in one place, and Modify gets them too ... The screen had been trimmed to controls with no explanation of what it was for; "Private to you" said who could see it, not what it did. It now opens with a sentence that says what you get and how you get it out, and the header reads "Only you can see these". The four choices — clinical library, PubMed, web, illustration — are one "Draw on" group instead of four separate rows, with the library ticked by default. Each option hides itself when an administrator has not enabled it, so nothing appears that a person could tick and then be refused. Modify offers exactly the same choices. It had none, so "add what the 2024 trial showed" was answered from the model's memory rather than by looking anything up. Generate and Modify now go through one gatherSources(), so they cannot drift into offering different things or searching them differently. Writing "include a diagram of the airway" in the instructions now switches the illustration option on and says why, rather than the request being dropped in silence. Switching it off by hand sticks — the hint then reminds instead of fighting — and when no image model is configured it says so rather than pretending. Both the generate and modify boxes behave this way. Two things found by testing this rather than assuming it. PubMed ANDs every mapped term, so one unrecognised word takes the query to zero. "febrile seizures" returns six results and "febrile seizures in under-fives" returns none; "the anatomy of croup: subglottic narrowing and the steeple sign" returned none until it was narrowed to "anatomy croup", which returns six. A query that finds nothing is now retried against progressively shorter versions of itself, longest first, and the response says which query actually worked so the screen cannot report one that found nothing. Those extra calls tripped NCBI's three-a-second limit and produced a 429, so retries are spaced and the first attempt waits for nothing. Separately, the searches run on the topic while the library retrieval also gets the instruction: retrieval is semantic and benefits from the context, but a keyword engine handed a whole sentence returns nothing. And when a search was asked for and came back empty, the prompt now says not to invent a citation, a PMID or a URL to fill the gap. Without that the model supplies them from memory, and a fabricated PMID looks exactly like a real one.

Daniel	1270899dcb	feat: PubMed search for My Resources, and an image tool that actually fires ... PubMed joins web search as an optional source for a generated resource: a literature search on the topic, with abstracts, cited by PMID in References. Off by default, admin-enabled, with its own optional API key (NCBI raises the rate limit from 3/sec to 10/sec; it works without one). Neither search is a tool any more, and that is the point. Offering them as function calls meant the model decided whether to search, and with a prompt ending "Output ONLY Pandoc markdown" it decided not to — every time, with and without corpus grounding, no matter how the tool description was worded. Calling callAI with the tool directly produced a correct pubmed_search call, so the plumbing was never the problem. The search only ever needed the topic, and the route knows the topic before it calls the model, so both searches now run up front and their results go into the prompt as findings, exactly the way corpus excerpts do. Ticking the box now means the search happened. Verified live against deepseek-v4-flash: 30 corpus excerpts and 6 PubMed results, and a References slide carrying both the library sources and four real PMIDs (29562151, 38506440, 35721052, 28814254). Three fixes to illustration, which had never once fired: - The dispatch call had been lost in a refactor. The tool was still offered, the model still called it, and the call was dropped, so no job was ever enqueued. - imageContext was passed as a bare topic string where dispatch expects { request, history }, which made the bound request undefined. - The prompt never mentioned the tool existed while explicitly demanding only markdown — the same suppression that killed the searches. It now says an illustration is available and that calling it is not a violation of that rule. my_resources is its own image workflow rather than a reuse of learning_hub, because generated_image_links only accepts learning_hub assets, and that is exactly the barrier that keeps a private illustration out of published content. The illustration renders in the panel, rather than a toast pointing at an image history this feature does not have. Verified end to end: job queued, rendered, and the asset served to its owner as a correctly labelled subglottic-anatomy teaching diagram.

Daniel	571a013d29	feat: optional web search, admin-enabled and off by default ... The one feature here that sends text outside the building, so the defaults are the careful ones: disabled unless an administrator turns it on, opt-in per generation even then, and the option is hidden entirely rather than shown as something a user can tick and be refused. Only the search query leaves. Library excerpts, the generated resource and anything about the user never do. Both screens say so plainly, because a topic typed while drafting clinical material can carry clinical detail and the provider keeps its own logs. Four providers behind one shape, so swapping changes nothing downstream: Tavily, Serper over Google, Brave, and SearXNG — the only one where the query does not reach a commercial third party at all, which is why it is worth supporting even though it needs somewhere to run. The tool description says when NOT to search, because a model handed a search tool will reach for it constantly: not for settled clinical knowledge, which is what the indexed library is for, and one search per resource. That last one is enforced in the route with toolChoice: 'none' on the continuation rather than trusted to the model. A failed search never fails a generation — same contract as corpus retrieval. The resource is written without it and the response says what was searched for and what came back, so a query that left the network is visible rather than silent. The API key is masked on read and preserved when the field is left blank, the handling the OIDC client secret already gets, so changing provider cannot silently wipe a working key. Verified on the running instance: with nothing configured, webSearchAvailable is false, and a request asking for it anyway is ignored rather than honoured.
