Business implication An unexpected departure of the top contributor would orphan 225 critical files and likely slow feature delivery by 3–5 weeks while the team learns the surface.
Establish a successor for Mason Daugherty (mason@langchain.dev)'s work — 225 files would orphan without them
Resilience is **Fragile** (50/100). Weakest dimension: review hygiene (F).
Risk inventory: 225 file(s) would become orphans if the top contributor leaves; 16 file(s) carry high correction load (≥35% fix/revert); 2 service(s) lack AI-readable operational context.
Top recommended action: Establish a successor for Mason Daugherty (mason@langchain.dev)'s work — 225 files would orphan without them
--api-key sk-ant-... --provider anthropic --model claude-sonnet-4-6or set
narrative.api_key in .blindspot.yaml.
Without a key, this rule-based narrator is used — deterministic,
in-process, no network.
Fragile resilience overall (score 50). Weakest dimension: AI operational readiness at 0.
Team-based Multiple maintainers without a single dominant contributor.
Six concrete questions, each with a one-number answer. This is the
report. Each signal opens up below into the files, services and people
behind its number — run with --detailed for the
architecture deep-dive.
Concrete next steps derived from the signals in this report. Each action is tied to a specific finding — treat them as conversation starters with the team, not directives.

Update CODEOWNERS for .github/ISSUE_TEMPLATE/bug-report.yml
Declared owners (@ccurme, @eyurtsev, @mdrxy) do not include the current top contributor. Mason Daugherty (mason@langchain.dev) holds 100% of effective ownership. Either add them to the CODEOWNERS rule or assign explicit cross-coverage.
▸ Declared owner does not include the actual top contributor (Mason Daugherty (mason@langchain.dev) at 100% coverage).

Each signal above, opened up — the files, services and people behind the headline number. Risk signals are expanded by default; healthy ones stay collapsed.
Bus factor measures how many people would need to leave before knowledge of a service is critically lost. A bus factor of 1 means a single person carries the service.
| Service | Files | Bus factor | Risk | Top owner | Their coverage |
|---|---|---|---|---|---|
.github |
42 | 1 | critical | Mason Daugherty (mason@langchain.dev) | 85% |

5 | 2 | high | Mason Daugherty (mason@langchain.dev) | 79% |

For each of the top contributors by aggregate ownership coverage, this is what would happen if they left tomorrow: how many files lose their primary expert, how many become unowned (orphan, top remaining coverage < 30%), and which services take the largest hit. Use this to prioritise pair-work and knowledge transfer.

Decay rises when an owner stops touching a file and others have been changing it. The 90-day projection shows the trajectory if nothing changes.
Review data fetched from GitHub (50 PRs analyzed). A rubber-stamp ratio is the share of approvals on a file that arrived without a single review comment. Reviewer diversity measures whether several people share the review load.
Share of recent commits to each file that are follow-up fixes or reverts. A high ratio is observable evidence of stability debt — work is shipping but corrections are paying for it. Look at the surface, not the person.
