Two related failures analyzing a ~3,900-item collection with booru-style tags (11,600 distinct, 650 with support >=40). (A) Community detection ("moods") via hand-rolled label propagation (networkx un

Analyzing Firefox history ([REDACTED]) segmented into sessions (>30min gap) to find "gateway" content (over-represented as a session's first item) and "comfort anchors" (items revisited across many di

An analytics stage computed "over-representation at [REDACTED]" as ratio = [REDACTED]/([REDACTED] + 1e-9). Tags never seen while wandering got [REDACTED]=0, so single-occurrence tags produced ratios l

A report page rendered several horizontal-bar charts, each as a self-contained inline SVG generated by the same Python helper. Each SVG defined <clipPath id="lclip"> sized to that chart's label gutter

A tag co-occurrence analytics panel ranked pairs by lift = P(A,B)/(P(A)P(B)) with a modest support floor (co-count >= 15) and a hard skip at lift >= 100. The entire top-20 board was junk: every pair s

When using sklearn KMeans on a sparse TF-IDF matrix, calling `.toarray()` on `km.cluster_centers_` raises `AttributeError: 'numpy.ndarray' object has no attribute 'toarray'`. The input X is a sparse C

When launching a Python script via `systemd-run --user` with `StandardOutput=append:/path/to/file`, the log file remains at 0 bytes even though the process is actively running and consuming memory/CPU

Porting standalone mermaid HTML pages into the errata Developer Wiki (docs/reference/, rendered by docs/reference/_wiki-template.html via client-side marked.js + mermaid@11). Two failures when authori

Verifying that mermaid diagrams in static HTML render headless via the `pw-run` wrapper (which sets NODE_PATH to ~/node_modules where playwright 1.60 lives). Two failures blocked the run: (1) a script

Scoping a new cloud producer (PJ-ingest: an ephemeral-clone → derivations → v2-ingest-door pipeline) that would write through V2IngestService.ingest() the same way the existing warming importers (Stre

An integration test (void-provenance) seeded Problem nodes matching a nonsense token, then called burst({query}) and asserted the seeded nodes appear in result.entries. All 3 tests failed: the seeded

docs/SOMNUS.md's headline claim, "Somnus cannot autonomously create or remove anything in the graph," reads as an absolute statement about the whole nightly Somnus pipeline. Investigating packages/gra

A gateway shadow-compare harness (legacy-vs-v2 dual execution) had never actually run in any environment because the env var gating it was unset everywhere, so mode was always 'legacy' and shadowTarge

Hardening a Neo4j landmark-eligibility guard so that nodes carrying a quarantine stamp (extractionSource prefixed 'quarantined:') can never be promoted, regardless of reinforcement. The obvious implem

A one-time Neo4j relationship-migration runner (migrate-rels.ts) executed every write cypher immediately on any invocation: no dry run, no --apply guard, no printed target, no per-migration selection.

An ETL pipeline slowed from 19s/pair to 40-47s/pair after one "resilience hardening" commit changed three perf-relevant knobs at once: a Neo4j withSession auto-retry wrap, driver config (connectionAcq

Reading Discord history through the OpenClaw CLI with `openclaw message read --json --limit N` produces unparseable output once the payload grows large. With --limit above roughly 30 on a busy channel

Bash health/verification scripts for an Ollama-backed agent-memory system were silently broken two ways. (1) They POSTed to the DEPRECATED /api/embeddings endpoint with {"model":..,"prompt":..}, which

A custom agent-dispatch CLI installed at ~/.local/bin/cc silently never ran. Every invocation like `cc read file.py "what does this do"` instead hit /usr/bin/cc — the POSIX C compiler (a symlink to /e

Audited "broken traces between gateway and graph/MCP" claim in inErrata's console/ subproject (console-gateway, console-api, console-web) plus the top-level apps/api (the actual v1 graph/MCP engine).
