feat: team.schema v2——对齐团队协作标准 v1.0 实例语义（ADR-0012）

[randypanding]

变更

解决 ADR-0011(team-collaboration) 遗留项（agent-registry#7）："team.schema（L0）需增 destroy_condition 字段与 re-check-sample 枚举值（实例侧已按语义对齐，schema 枚举滞后——跨仓 PR）"。

standards/agent/team.schema.yaml v1 → v2（$id team@2）：

1. destroy_condition（遗留项点名）

lifecycle.destroy_condition：销毁语义条件，与 destroy_policy: after-handoff 是 AND 关系——移交完成只表达"资产安全"，不表达"任务语义上该结束"。实例：dev-wave released_behind_flag OR reverted；incident-cell exit_criteria 满足。destroy_scope（agent 实例与临时 workspace；数据层制品不随队销毁）入 description。

2. re-check-sample 枚举值（遗留项点名）

coverage 枚举 [all-outputs, sampled] → [all-outputs, sampled, re-check-sample]：表达前道全审 + 后道抽检复核的双层验证（attention-ledger.sampled 语义——curator 全审在前、owner 抽检 10% 复核）。external_audit.method 的 re-check-sample（审计方法）v1 已有，本 PR 使 coverage（验收覆盖）同可表达。

3. 枚举/结构滞后清理（同类问题一并解决，不留新遗留）

实测 v1 schema 校验三实例 = 13 处不符（v2 全 PASS，见验证）：

• topology + single-seat；frequency + per-incident；handoff + incident_report/retro_24h/followup_backlog_merge/retro_debt_tracking
• lifecycle + trigger/ttl/on_ttl_expiry（TTL 到期绝不 auto-destroy）
• 顶层 + archetype/scope/budget/backlog_role；members + seat（时序成员位）；orchestration + phases_ref/release/authorization_ref
• assign/merge 三选一枚举废弃为机制描述 string（实例语义是"机制名+关键规则"）
• layout + contracts/findings/backlog；governance-core 引用更正为 stewardship（v1.0 拆分）

验证

• jsonschema Draft202012 实测：v1 → dev-wave 3 处 / incident-cell 7 处 / stewardship 3 处不符；v2 三实例全 PASS
• gate.yml 等价本地检查：YAML 全量解析 OK（9 files）、脚本语法 OK
• drift-check 本地预检（C1 要求）：无漂移（main 已含 chore(governance): 放行 harden-runner/scorecard-action + scorecard 周扫 #15 后）

流程

C1（standards/ 变更）：PR + ADR-0012（agent-registry/decisions/ADR-0012-team-schema-v2.md，随后 PR）+ owner merge。

附带发现（不在本 PR 处理）：main 上存在两个 ADR-0011（runtime-egress / team-collaboration，编号冲突），ADR-0012 将记录消歧约定。

Suggested labels: breaking, feature

Merge Risk: 🟡 Moderate · up to f147f

The schema update still allows malformed topology values and incomplete ephemeral lifecycle configurations to pass validation, which could admit invalid team definitions into the repository. These bounded correctness issues should be fixed before merge.

Align team schema v2 with collaboration v1.0 semantics

✨ Enhancement 🐞 Bug fix ⚙️ Configuration changes 🕐 20-40 Minutes

AI Description

• Upgrades team schema to v2, aligning three registry team archetypes.
• Models lifecycle guards, verification coverage, budgets, and orchestration metadata.
• Expands constrained values to validate existing team instances without schema drift.

High-Level Assessment

The following are alternative approaches to this PR:

1. Generate schema from collaboration standards

• ➕ Reduces drift between the canonical collaboration model and validation schema
• ➕ Makes future archetype and enumeration changes reproducible
• ➖ Requires a generator, source annotations, and CI integration
• ➖ May be difficult while semantic rules remain prose-oriented

2. Use archetype-specific oneOf branches

• ➕ Enforces required fields and legal values for each team archetype
• ➕ Catches invalid lifecycle and orchestration combinations earlier
• ➖ Duplicates semantics owned by the collaboration standard
• ➖ Creates tighter coupling and more complex compatibility migrations

Recommendation: Keep the PR's compatibility-first v2 schema because it resolves current registry validation failures without duplicating each archetype's complete semantic model. Consider generation from the canonical collaboration standard as a follow-up if schema drift recurs; archetype-specific branches should be reserved for stable, machine-enforceable invariants.

Evolve the team declaration contract to schema v2

• Updates the schema identifier and aligns team declarations with collaboration v1.0 semantics. Adds lifecycle destruction and TTL fields, richer orchestration, verification, budget, workspace, membership, and scope metadata, while expanding enums and relaxing mechanism fields to accept existing registry instances.

🐞 Bugs (1) 📘 Rule violations (0) 📜 Skill insights (0)

1. Destruction invariant remains optional ✗ Dismissed 🐞 Bug ≡ Correctness

Description

The schema states that ephemeral destruction requires both completed handoff and
destroy_condition, but lifecycle still requires only type, so an ephemeral team without either
field validates. This defeats the primary v2 lifecycle invariant and permits premature destruction
semantics.

Code

standards/agent/team.schema.yaml[R135-137]

+      destroy_condition:
+        type: string
+        description: "销毁语义条件（ADR-0012 增；与 destroy_policy=after-handoff 是 AND 关系）：delivery_squad 如 released_behind_flag OR reverted；incident_cell 如 exit_criteria 满足（service_restored AND root_cause_hypothesis AND followup_cards_created）。销毁范围（destroy_scope）=agent 实例与临时 workspace；数据层制品/事件不随队销毁"

Evidence

The schema's top-level description defines ephemeral destruction as `after-handoff AND
destroy_condition, while lifecycle.required contains only type`; all fields needed to enforce
that invariant remain optional properties.

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Enforce the documented ephemeral lifecycle invariant through JSON Schema rather than descriptions alone.

## Issue Context
For `type: ephemeral`, require `archive_to`, `handoff`, `destroy_policy`, and `destroy_condition`, and constrain `destroy_policy` to `after-handoff`. Preserve the intended persistent-team behavior as appropriate.

2. Topology accepts arbitrary suffixes 🐞 Bug ≡ Correctness

Description

The new topology regex matches only a valid prefix, so values such as flat-invalid or `single-seat
garbage` pass validation. The documented syntax permits only a standard value with an optional
parenthesized annotation.

Code

standards/agent/team.schema.yaml[R43-45]

+    type: string
+    pattern: "^(leader-teammate|flat|hub-spoke|single-seat)"
+    description: "标准值开头，可附括号尾注：leader-teammate（leader 可为 mechanism:scheduler——openjiuwen 形态）/ flat / hub-spoke / single-seat（常驻单座位团队：stewardship、incident_cell）"

Evidence

The regex starts with a topology alternation but has no end anchor or annotation grammar;
consequently any string beginning with one of those alternatives satisfies the pattern, contrary to
the adjacent description.

standards/agent/team.schema.yaml[42-45]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Constrain topology values to an exact standard value or a standard value followed by the documented parenthesized annotation.

## Issue Context
Add an end anchor and explicitly define the optional ASCII or full-width parenthesized suffix rather than accepting every continuation.

3. Archetype accepts unknown values ✗ Dismissed 🐞 Bug ≡ Correctness

Description

The new archetype field accepts every string even though its description defines only three
supported archetypes. Misspellings and archetypes without the required ADR can therefore pass schema
validation and reach consumers without defined semantics.

Code

standards/agent/team.schema.yaml[R21-23]

+  archetype:
+    type: string
+    description: "团队原型（team-collaboration PART 2 teams.*：delivery_squad | stewardship | incident_cell）；新增原型须 ADR 论证"

Evidence

The allowed archetypes occur only in the description, while the actual constraint is merely `type:
string`. The neighboring agent schema demonstrates the repository convention of enforcing a declared
archetype set with an enum.

standards/agent/team.schema.yaml[21-23]
standards/agent/agent.schema.yaml[20-25]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
Restrict team archetypes to the currently supported values so invalid or unapproved declarations fail validation.

## Issue Context
Use an enum containing `delivery_squad`, `stewardship`, and `incident_cell`; update that enum when an ADR adds another archetype.

- Around line 44-45: Update the topology pattern in the schema so it matches
only the four standard values, optionally followed by the documented
parenthesized note, and rejects trailing text such as flat-invalid or
single-seat text. Anchor the complete expression at both ends while preserving
the existing leader-teammate, flat, hub-spoke, and single-seat values.
- Around line 119-137: Update the team schema’s conditional validation so
entries with type ephemeral require archive_to, handoff, destroy_policy, and
destroy_condition, while persistent entries retain their existing requirements.
Anchor the change to the type property and the surrounding archive_to, handoff,
destroy_policy, and destroy_condition definitions, using the schema’s supported
conditional mechanism.
