docs: scope expansion (Pairing mode) + mode-letter rename (#99)
Two changes landed together because the rename also introduces
the new mode:
1. Apply Russell Spitzer's kickoff-thread feedback: extend the
project's scope from agent-assisted maintainership to
maintainership AND development. New "Pairing" mode covers
developer-side dev-cycle skills (multi-agent dev workflow,
self-review and pre-flight patterns, scoped agent-drafted
patches under the developer's own driver's seat). Mentorship
is intrinsic to Pairing — agents handle implementation-detail
review so the human conversation stays on design, reasoning,
and the ASF contributor → committer → PMC progression.
Pairing ships before Auto-merge in the project's automation
roadmap.
2. Rename Mode A/B/C/D to single-word names so references read
without lookup:
Mode A → Triage
Mode B → Mentoring
Mode C → Drafting
(new) → Pairing
Mode D → Auto-merge
Auto-merge's gating sentence updated to require Triage,
Mentoring, Drafting, AND Pairing running for two quarters
before it can ship.
Touches MISSION.md, docs/modes.md (canonical taxonomy doc),
docs/rfcs/RFC-AI-0004.md, docs/security/threat-model.md,
docs/mentoring/{README,spec}.md, the pr-management-mentor skill
files, the projects/_template/mentoring-config.md scaffold, the
.asf.yaml description, and the skill-validator code + tests
(ALLOWED_MODES updated). DocToc TOCs regenerated by prek.

+Apache `<PROJECT_NAME>` is platform infrastructure for **agent-assisted
repository maintainership and development** — across the ASF and equally for
any open-source project that wants in. Four streams of day-to-day work:
- **Security-issue handling** end-to-end — inbound triage, deduplication,
agent-drafted reporter replies under human review, CVE allocation hand-off,
audit-logged status tracking through publication.
- **Issue and PR triage and management** — including audit-tool findings
(Apache Verum, Apache Caer, equivalents) ingested as actionable issues.
- **Conversational contributor mentoring** — meeting new contributors where
they are.
+- **Development-cycle skills for committers and contributors, mentorship built
in** — multi-agent development workflows, self-review and pre-flight patterns,
scoped agent-drafted patches under the developer's own driver's seat.
Mentorship is intrinsic, not a separate mode: the agent handles
implementation-detail review (formatting, conventions, lint-grade nits) so the
human conversation between contributor and maintainer — and between peer
maintainers — stays on design, reasoning, and th [...]
One conviction underneath: each project picks how much automation actually
fits. The platform makes a range of automation levels possible without picking
one for you, and "project" means both an ASF PMC and any non-ASF community —
neither is a second-class citizen.

- Stand up `github.com/apache/<PROJECT_NAME>` with project skeleton, CI, and
contributor docs.
- Provision standard ASF infrastructure: `private@`, `dev@`, `commits@`;
GitHub Issues; site at `<PROJECT_NAME>.apache.org`.

least one ASF PMC running the full security-issue flow (Airflow, given the
project's lineage), one ASF PMC running just triage + mentoring (Arrow or ATR),
and **at least one non-ASF project from day one** (Python core has folks
interested). Non-ASF in the first cohort, not later — the
project-governance-agnosticism claim is only worth what it can prove.

later — the project-governance-agnosticism claim is only worth what it can
prove.
- Cut a first Apache release through the standard process within 3 months of
resolution adoption, with artefacts usable directly by non-ASF adopters (no
ASF-only assumption baked into the install path).
-- Wire modes A–C up to Apache Verum and Apache Caer findings, and to at least
one non-ASF audit-tool equivalent (a CodeQL output stream is the likely first
non-ASF case).
+- Wire **Triage**, **Mentoring**, and **Drafting** up to Apache Verum and

intrinsic — multi-agent review or pre-flight self-review — demonstrated against
a friendly-pilot project's contributor dev loop, so the
maintainership-and-development scope claim and the
human-relationship-preservation claim both have working code to point at.
- Settle on a contributor-sentiment evaluation methodology with Apache Plumb
(separate proposal). Eval covers both ASF and non-ASF cohorts so the data isn't
an internal-ASF artefact.
- **Ship the privacy and security posture** as a release-blocking part of v1 —
sandbox setup, clean-env wrapper, privacy-LLM gate, PII redactor, signed
releases, pinned-tools manifest. Not a follow-up.
- **Ship the maintainer-education stream** alongside v1 — pattern catalogue,
"your first skill" path, first scheduled workshops. The platform is only as
adoptable as the docs that go with it.

(Gmail, PonyMail, Vulnogram, generic CVE submission, an extensible adapter
layer so non-ASF adopters plug in their own equivalents) — with five modes
built on top.
[`docs/modes.md`](docs/modes.md) is the honest snapshot mapping each mode
below to the skills currently shipped, with a `stable / experimental / proposed
/ off` status legend.
-**Mode A — triage assistant** for issues, security reports, and PRs. *On the
security side:* spots inbound reports, classifies against prior triaged cases,
surfaces likely duplicates, identifies anything that should not have been filed
publicly, proposes initial routing to the security team. *On the regular side:*
suggests labels, spots duplicates, links related discussions, proposes routing.
Every output is a suggestion the human signs off on; nothing lands without
review. Lowest risk surface.

+**Mentoring** — conversational. Joins issue and PR threads in a deliberately
teaching register: clarifying questions, pointers to project conventions and
docs, an explanation of *why* a change is being asked for, paired examples from
similar prior PRs, clean hand-off to a human reviewer when the question exceeds
what an agent should answer. The differentiator and the highest-value
project-side mode — where the Responsible AI Initiative's empowerment outcome
lives.

for a well-scoped problem (a tracked issue, a triaged security report with team
consensus on scope, an Apache Verum or Apache Caer finding, a failing test with
an obvious cause, a documentation hole) and opens a PR. Every PR is reviewed

project-side modes above — which describe the project's agent presence on its
own infrastructure — the platform also ships skills that maintainers and
contributors run in their *own* dev loop: multi-agent review pipelines,
self-review and pre-flight patterns, scoped fix drafting under the developer's
driver's seat. Pairing skills don't make state changes on behalf of the
project; they're the developer's indivi [...]

objectively boring change classes — lint fixes, dependency bumps inside an
allow-list, license-header insertion, formatting, broken-link repair.

logged. **Not turned on** until A/B/C have been running for two quarters and

from, where audit findings come from, what the release process expects), full
audit logging and rollback for every agent-authored change — security and
non-security alike — and an integration hook for the Apache Plumb eval

+## Pairing
+
+**Status: proposed. No skill yet.**
+
+[`MISSION.md` § Pairing](../MISSION.md#technical-scope) introduces
+this mode as the developer-side counterpart to the project-side
+modes. Where Triage / Mentoring / Drafting / Auto-merge describe
+the agent's presence on the project's own infrastructure, Pairing
+skills run in the maintainer's or contributor's *own* dev loop —
+multi-agent review pipelines, self-review and pre-flight patterns,
+scoped fix drafting under the developer's driver's seat.
+**Mentorship is intrinsic** to Pairing skills: the agent handles
+the mechanical, implementation-detail review (formatting,
+conventions, lint-grade nits) so the human conversation between
+contributor and maintainer — and between peer maintainers —
+stays on design, reasoning, and the trade-offs the project cares
+about. Pairing skills are the platform's mechanism for protecting
+the **ASF contribution path** (contributor → committer → PMC)
+against being eroded by automation that replaces, rather than
+augments, the human-to-human relationships that path is built on.
+
+Pairing skills don't make state changes on behalf of the project;
+they share the same skill format and security posture as the
+project-side modes, so a maintainer who already trusts the
+framework for Triage gets the same posture for the patches they
+write themselves.
+
+**Sequencing.** Pairing ships before Auto-merge in the project's
+automation roadmap — full auto-merge of maintainer-driven changes
+follows only after Pairing has established that human reasoning
+and relationships, not implementation chatter, are the
+load-bearing parts of the workflow.

folder. The maintainer reviews and presses Send. The framework MUST NOT have a
"yes, send the draft" path that bypasses the human read.
5. **Audit log of every confirmation.** Every applied state change writes a
structured audit-log entry: timestamp, maintainer identity, proposal text,
applied diff, triggering skill. Open-source maintenance is a public-trust
activity; the trail makes future review possible.

+Auto-merge ("narrowly-scoped fix-and-merge", in Apache Steward (to be
renamed)'s terminology) is the explicit exception. It permits auto-merge, but
only after **all** of the following gate conditions hold:
- The change class is on a per-project, per-class allow-list (lint fixes,
dependency bumps within an allow-list, license headers, formatting, broken-link
repair). Security-class changes are explicitly out.

confirmation for at least two release cycles, and a contributor-sentiment
evaluation says the project is healthier, not just faster.
- Every auto-merged change is reversibly logged; reverts are one keystroke
away.
The carve-out exists because lint-rebase-format has marginal human value and
should not require a human in the loop forever. It is **off by default** in the
reference implementation. A project that turns it on without first running the
manual loop has skipped the proof.
