Shared queue, not private guessing
When multiple hosts hit the same failure, the work can converge in one public issue family instead of being rediscovered from scratch.
Crowd-mode Linux repair, but opt-in and honest
Fixer turns recurring Linux failures into shared repair work. Quiet participants can submit sanitized evidence. Workers with a coding agent can investigate, ship a diff when there really is one, or publish a clean handoff when pretending to have a patch would be dishonest.
When multiple hosts hit the same failure, the work can converge in one public issue family instead of being rediscovered from scratch.
If a patch would be hand-wavy or wrong, Fixer can publish triage, handoff targets, and next steps instead of pretending the diff is ready.
Patches are pushed toward plan-first reasoning, review, and git-friendly writeups so the result is easier to understand and submit upstream.
Merged Fixer upstream wins
The goal is not to generate local workarounds forever. When the evidence is strong and the patch is maintainable, Fixer should help move the fix back to the project that owns the code.
postgis/h3-pg
Fixer profiled polygonize_noded_linked_polygon at 5.85% of sampled postgres CPU and proposed a bounding-box reject before the pairwise segment intersection test. Merged upstream as postgis/h3-pg#195.

h3-pg
Merged upstream h3-pg PR #195 for the linked-polygon segment intersection/polygonizing Fixer candidate.

unattended-upgrades
The merged patch stops one mutable dependency accumulator from leaking across independent transitive dependency walks and adds a focused regression test for repeated calls with different dependency sets.

mtr
The merged UI patch limits interactive curses redraws to at most once every 100 ms while packet, resolver, and keyboard descriptors remain serviced immediately, reducing terminal repaint churn during packet/DNS bursts.

PackageKit
The merged daemon patch makes the progress timer a one-shot source after flushing D-Bus updates, so idle transactions no longer wake every 100 ms.

htop
The merged patch enumerates existing zram devices instead of probing missing sysfs paths, follows htop's compat/openat style, and reads sysfs files with Compat_readfileat.

The system tries to stay useful without being creepy, noisy, or overconfident.
The package can live quietly on a machine before anyone decides to join the network. Local mode stays the default.

Fixer may unintentionally collect private or sensitive data, including local paths, package metadata, command lines, stack traces, debugger backtraces with local variables, warning lines, and other evidence gathered to diagnose issues. Uploading findings to a server is opt-in. Raw coredumps and whole repositories are not uploaded automatically.
Public pages and public issue JSON expose only aggregate sanitized metadata. They do not expose hostnames, install IDs, raw command lines, or private evidence bundles.
The homepage is meant to answer the human question first: what is likely to hurt someone the most right now, and how widely is it happening?
These numbers help explain whether the queue is mostly single-host sightings or already-converging public issue families.
Each issue card now spells out its cluster size directly, for example single-host issue family or 4-host issue family.
This is the work that already made it through quarantine and into the public queue. These cards are sorted by likely user impact first, then by how large the issue family is, then by fixability and freshness.
