Some Ollama installs ship nomic-embed-text:v1.5 with the embedding
model's default num_ctx=2048, which the RAG chunker (sized for ~1500
tokens of estimated content with ratio=2 chars/token) can exceed on
dense PDFs. The result is `400 the input length exceeds the context
length` from /api/embed, which then hits the OpenAI-compatible
fallback (which also errors), and surfaces as a BadRequestError.
Pass options.num_ctx=8192 (nomic-embed-text v1.5's RoPE-extrapolated
max) and truncate=true (silent truncation safety net) on every
embed call so we don't depend on the local modelfile defaults.
Reported on #756 by @NC4WD; same root cause as #369 and #670 which
were closed without an actual fix.

Closes#685
Content Manager now surfaces the on-disk size of each ZIM file alongside
title/summary, and lets users sort the list by Size or Title. Defaults to
Size descending so the largest files are visible first.
- ZimService.list() now stats each file and returns size_bytes
- Content Manager table adds a formatted Size column (via formatBytes)
- Sortable headers for Title and Size with asc/desc toggle
Three bugs in the RAG embedding pipeline, diagnosed and patched by @sbruschke
against v1.31.0 with working before/after chunk counts. All three are
root-cause contributors to #388.
1. scanAndSyncStorage queued every file under /storage/zim/ for embedding,
including Kiwix's generated kiwix-library.xml. EmbedFileJob rejected it
with "Unsupported file type" and the default 30-attempt retry policy
kept it looping on every sync, flooding nomad_admin logs. Now gated on
determineFileType(filePath) !== 'unknown'.
2. hasMoreBatches compared zimChunks.length (section-level chunk count
under the 'structured' strategy) against ZIM_BATCH_SIZE (an article
limit). Because articles emit multiple sections, the two are never
equal for real archives and processing silently stopped after the
first 50 articles. Now gated on articlesInBatch >= ZIM_BATCH_SIZE.
3. extractStructuredContent walked only direct children of <body>, so any
ZIM that wraps content in a container div (Devdocs, Wikipedia,
FreeCodeCamp, React docs, etc.) produced zero sections and silently
embedded zero chunks while reporting success. Now walks the full DOM
via $('body').find('h2, h3, h4, p, ul, ol, dl, table'), with a
whole-body text fallback when the selector walk yields nothing.
Before/after chunk counts confirmed by @sbruschke on v1.31.0:
devdocs_en_git 0 -> 916
devdocs_en_react 0 -> 481
devdocs_en_node 0 -> 423
libretexts_en_eng 1 -> 35 (climbing)
Wikipedia resumed progressing normally through its 6M articles.

When many ZIMs are already installed locally, a single Kiwix catalog page
(12 items) could return 12 already-installed items, which zim_service
would fully filter out client-side. The endpoint returned items: [] with
has_more: true, and the frontend's infinite-scroll guard
(flatData.length > 0) blocked fetchNextPage — leaving the user with
"No records found" despite plenty of uninstalled ZIMs available.
Backend now accumulates across up to 5 Kiwix fetches (60 items each)
until it has enough post-filter results to return, dedupes by entry id,
advances currentStart by actual entries returned (not requested), and
returns a next_start cursor. The frontend consumes that cursor instead
of computing Kiwix offsets locally, and the flatData.length > 0 guard is
removed so the existing on-mount effect drives bounded auto-fetch when
a short page lands.
The pre-existing has_more off-by-one (compared totalResults against the
input start rather than the post-fetch position) is fixed implicitly.

Adds a cancel button to in-progress Ollama model downloads and unifies
the Active Model Downloads card layout with the Active Downloads card
used for ZIMs, maps, and pmtiles (byte counts, progress bar, live speed,
status indicator).
Closes#676.
Corrupted ZIM files cause a native C++ abort (ZimFileFormatError) that
bypasses JS try/catch and kills the process. Add magic number validation
before passing files to @openzim/libzim so invalid files are skipped
gracefully. Also deduplicate Ollama download progress broadcasts — both
within a single stream (skip unchanged percentages) and across concurrent
callers (share one download promise per model).

* fix(downloads): increase retry attempts and backoff for large file downloads
* fix download retry config and abort handling
* use abort reason to detect user-initiated cancels
New defaults:
OLLAMA_NO_CLOUD=1 - "Ollama can run in local only mode by disabling
Ollama’s cloud features. By turning off Ollama’s cloud features, you
will lose the ability to use Ollama’s cloud models and web search."
https://ollama.com/blog/web-searchhttps://docs.ollama.com/faq#how-do-i-disable-ollama%E2%80%99s-cloud-features
example output:
```
ollama run minimax-m2.7:cloud
Error: ollama cloud is disabled: remote model details are unavailable
```
This setting can be safely disabled as you have to click on a link to
login to ollama cloud and theres no real way to do that in nomad outside
of looking at the nomad_ollama logs.
This one can be disabled in settings in case theres a model out there
that doesn't play nice. but that doesnt seem necessary so far.
OLLAMA_FLASH_ATTENTION=1 - "Flash Attention is a feature of most modern
models that can significantly reduce memory usage as the context size
grows. "
Tested with llama3.2:
```
docker logs nomad_ollama --tail 1000 2>&1 |grep --color -i flash_attn
llama_context: flash_attn = enabled
```
And with second_constantine/deepseek-coder-v2 with is based on
https://huggingface.co/lmstudio-community/DeepSeek-Coder-V2-Lite-Instruct-GGUF
which is a model that specifically calls out that you should disable
flash attention, but during testing it seems ollama can do this for you
automatically:
```
docker logs nomad_ollama --tail 1000 2>&1 |grep --color -i flash_attn
llama_context: flash_attn = disabled
```
* feat(downloads): rich progress, friendly names, cancel, and live status
Redesign the Active Downloads UI with four improvements:
- Rich progress: BullMQ jobs now report downloadedBytes/totalBytes instead
of just a percentage, showing "2.3 GB / 5.1 GB" instead of "78% / 100%"
- Friendly names: dispatch title metadata from curated categories, Content
Explorer library, Wikipedia selector, and map collections
- Cancel button: Redis-based cross-process abort signal lets users cancel
active downloads with file cleanup. Confirmation step prevents accidents.
- Live status indicator: green pulsing dot with transfer speed for active
downloads, orange stall warning after 60s of no data, gray dot for queued
Backward compatible with in-flight jobs that have integer-only progress.

* fix(downloads): fix cancel, dismiss, speed, and retry bugs
- Speed indicator: only set prevBytesRef on first observation to prevent
intermediate re-renders from inflating the calculated speed
- Cancel: throw UnrecoverableError on abort to prevent BullMQ retries
- Dismiss: remove stale BullMQ lock before job.remove() so cancelled
jobs can actually be dismissed
- Retry: add getActiveByUrl() helper that checks job state before
blocking re-download, auto-cleans terminal jobs
- Wikipedia: reset selection status to failed on cancel so the
"downloading" state doesn't persist

The log2 normalization formula `50 * (1 + log2(ratio))` produces negative
values (clamped to 0) whenever the measured value is less than half the
reference. For example, a CPU scoring 1993 events/sec against a 5000
reference gives ratio=0.4, log2(0.4)=-1.32, score=-16 -> 0%.
Fix by dividing log2 by 3 to widen the usable range. This preserves the
50% score at the reference value while allowing below-average hardware
to receive proportional non-zero scores (e.g., 28% for the CPU above).
Also adds debug logging for CPU sysbench output parsing to aid future
diagnosis of parsing issues.
Fixes#415
Model downloads that fail (e.g., when Ollama is too old for a model)
were silently retrying 40 times with no UI feedback. Now errors are
broadcast via SSE and shown in the Active Model Downloads section.
Version mismatch errors use UnrecoverableError to fail immediately
instead of retrying. Stale failed jobs are cleared on retry so users
aren't permanently blocked.

GPU detection results were only applied at container creation time and
never persisted. If live detection failed transiently (Docker daemon
hiccup, runtime temporarily unavailable), Ollama would silently fall
back to CPU-only mode with no way to recover short of force-reinstall.
Now _detectGPUType() persists successful detections to the KV store
(gpu.type = 'nvidia' | 'amd') and uses the saved value as a fallback
when live detection returns nothing. This ensures GPU config survives
across container recreations regardless of transient detection failures.

Failed download jobs persist in BullMQ forever with no way to clear
them, leaving stale error notifications in Content Explorer and Easy

- Frontend: X button on failed download cards with immediate refresh

Three bugs caused downloads to hang, disappear, or leave stuck spinners:
1. Wikipedia downloads that failed never updated the DB status from 'downloading',
leaving the spinner stuck forever. Now the worker's failed handler marks them as failed.
2. No stall detection on streaming downloads - if data stopped flowing mid-download,
the job hung indefinitely. Added a 5-minute stall timer that triggers retry.
3. Failed jobs were invisible to users since only waiting/active/delayed states were
queried. Now failed jobs appear with error indicators in the download list.

4. SSRF on download endpoints — block private/internal IPs, require TLD
Also adds assertNotPrivateUrl() to content update endpoints.

Ollama can silently run on CPU even when the host has an NVIDIA GPU,
resulting in ~3 tok/s instead of ~167 tok/s. This happens when Ollama
was installed before the GPU toolkit, or when the container was
recreated without proper DeviceRequests. Users had zero indication.
Adds a GPU health check to the system info API response that detects
when the host has an NVIDIA runtime but nvidia-smi fails inside the
Ollama container. Shows a warning banner on the System Information
and AI Settings pages with a one-click "Reinstall AI Assistant"
button that force-reinstalls Ollama with GPU passthrough.

The previous lspci-based GPU detection fails inside Docker containers
because lspci isn't available, causing Ollama to always run CPU-only
even when a GPU + NVIDIA Container Toolkit are present on the host.
Replace with Docker API runtime check (docker.info() -> Runtimes) as
primary detection method. This works from inside any container via the
mounted Docker socket and confirms both GPU presence and toolkit
installation. Keep lspci as fallback for host-based installs and AMD.
Also add Docker-based GPU detection to benchmark hardware info — exec
nvidia-smi inside the Ollama container to get the actual GPU model name
instead of showing "Not detected".
Tested on nomad3 (Intel Core Ultra 9 285HX + RTX 5060): AI performance
went from 12.7 tok/s (CPU) to 281.4 tok/s (GPU) — a 22x improvement.

Inside Docker, systeminformation reports the container's Alpine Linux
distro, container ID as hostname, and no GPU. This enriches the System

- GPU model and VRAM via nvidia-smi inside the Ollama container
- Graphics card in System Details (Model, Vendor, VRAM)
- Friendly uptime display (days/hours/minutes instead of minutes only)

Removes the InstalledTier model and instead checks presence of files on-the-fly. Avoid broken state by handling on the server-side vs. marking as installed by client-side API call
Content Manager now shows Title and Summary columns from Kiwix metadata
instead of just raw filenames. Metadata is captured when files are
downloaded from Content Explorer and stored in a new zim_file_metadata
table. Existing files without metadata gracefully fall back to showing
the filename.
Changes:
- Add zim_file_metadata table and model for storing title, summary, author
- Update download flow to capture and store metadata from Kiwix library
- Update Content Manager UI to display Title and Summary columns
- Clean up metadata when ZIM files are deleted

When running in Docker, the systeminformation library cannot see the
host's GPU hardware. This adds a fallback to detect Intel integrated
graphics from the CPU model name, similar to how we handle AMD APUs
with Radeon graphics.
Intel Core Ultra processors (Meteor Lake, Arrow Lake) include Intel
Arc Graphics integrated. This change detects "Core Ultra" in the CPU
brand and reports "Intel Arc Graphics (Integrated)" as the GPU model.
Note: This is for display purposes only - Ollama does not support
Intel integrated graphics for AI acceleration.
