Tighten _is_failed: exclude successful hub JSON responses (top-level no-error
payloads) and file-read snapshots (numbered cat -n source lines) that were
polluting error_snippets. JSON verdict classifies error vs success payloads
directly. Cuts distinct fingerprints 444 -> 269 (~40%) over the real corpus with
the top errors unchanged. Assessment caveat updated. 5 new tests; suite 102/102.

Re-ingested under schema v2 (populates error_snippets) and re-ran detect over
27 real sessions. Added a 'content-level root causes' section to
docs/ASSESSMENT-infra-friction.md: top recurring error is Edit/Write-before-Read
(12/27 sessions, 8 repos), then stale-read conflicts, a cross-flavor (claude+grok)
make fix-consistency failure, and State Hub MCP instability. Documented a
fingerprint-noise caveat. WP-0006 finished; suite 98/98.

Re-ran ingest->detect with the quality filter + infra signals over real local
sessions (72 captured -> 27 real). Purged the false-positive 'abandoned' catalog
entry and re-curated; catalog now carries tool_thrash/schema_thrash/infra_overhead
patterns. docs/ASSESSMENT-infra-friction.md ranks the friction: ~17.6% of real
tool activity is hub/task/schema plumbing (State Hub 10.3%, one session 231 calls;
ToolSearch in 81% of sessions). Validates the CLI/MCP-skill hypothesis as top-2;
recommends a State Hub skill (front-load schemas + batched writes) + bulk hub ops.
Workplan finished; suite 88/88.
