# FLEX-WP-0040 — Bounded execution PDP gate
|
|
|
|
NetKingdom's proposed Bounded Execution Admission v0.1 (NK-WP-0056) lets the
|
|
founder approve, at `aal2`, an exact digested admission that a bounded executor
|
|
consumes once. Owner answer: `docs/bounded-execution-admission-pdp.md`. PDP
|
|
gating is in scope and recommended for production; the T06 pilot may run on
|
|
local enforcement without it.
|
|
|
|
Today the typed task path (`docs/trusted-service-task-source.md`) serves only
|
|
the secrets-engine v2 contract, requires an unconsumed claim, and the Approval
|
|
claim carries no approver assurance. Everything below lands as `proposed`
|
|
source, evaluated in tests only. No deployment, caller trust or credential is
|
|
admitted by this workplan.
|
|
|
|
## 1. Settle the claim inputs with approval-engine
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T01
|
|
status: wait
|
|
priority: high
|
|
```
|
|
|
|
Wait: approval-engine answers to NK-WP-0056-T02 (binding to
|
|
`{admission_id, admission_digest}`, approver assurance `aal2`, consume scope)
|
|
plus our two additions: `consumed_by` and `consumed_at` in the claim. Record
|
|
the agreed claim fields here. Gate: written claim field list with owner ack.
|
|
|
|
## 2. Pack owner and semantic review
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T02
|
|
status: wait
|
|
priority: medium
|
|
```
|
|
|
|
Wait: founder confirms the proposal — access-engine owns pack mechanics and
|
|
fixtures; NetKingdom (BEA owner) owns what a ceiling admits; gate-house reviews
|
|
authority-ceiling semantics. Gate: decision recorded.
|
|
|
|
## 3. Generalise the typed path caller map
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T03
|
|
status: todo
|
|
priority: medium
|
|
```
|
|
|
|
Replace the single hard-wired secrets-engine mapping with an owner-installed
|
|
caller map; first new entry `system:serviceaccount:sso:nk-bind-executor` →
|
|
`service:nk-bind-executor`. Gate: existing secrets-engine v2 tests unchanged
|
|
and passing; unknown service accounts refuse; generic `/v1/check` still refuses
|
|
task execution.
|
|
|
|
## 4. Vocabulary and admission digest
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T04
|
|
status: todo
|
|
priority: medium
|
|
depends_on: [FLEX-WP-0040-T01]
|
|
```
|
|
|
|
Add actions `start` and `execute-step` on resource type
|
|
`bounded-execution-admission` (system `net-kingdom`). The executor submits the
|
|
admission document; access-engine recomputes its digest by NK's BEA digest rule
|
|
and requires equality with the claim's admission digest. Gate: digest fixtures
|
|
shared with NetKingdom's validator agree byte-for-byte.
|
|
|
|
## 5. Policy pack `net-kingdom.bounded-execution` (DENY by default)
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T05
|
|
status: todo
|
|
priority: medium
|
|
depends_on: [FLEX-WP-0040-T02, FLEX-WP-0040-T03, FLEX-WP-0040-T04]
|
|
```
|
|
|
|
`start`: claim valid and unconsumed, approver HUMAN at `aal2` and not the
|
|
executor, executor equals admission executor, now inside `window`.
|
|
`execute-step`: claim consumed once by this executor inside the window; step
|
|
id/operation/target/mode/scope match the digested `plan.steps` and lie inside
|
|
`scope_ceiling`; `max_concurrent` respected. Fixtures from
|
|
`net-kingdom/examples/bounded-execution-admission/bind-rotation-svc-authelia.yaml`
|
|
including out-of-ceiling, wrong executor, expired window, replayed consume and
|
|
missing assurance. Gate: pack validates, all fixtures pass, the existing
|
|
`apply` gap test stays as characterisation.
|
|
|
|
## 6. Live gate readiness
|
|
|
|
```task
|
|
id: FLEX-WP-0040-T06
|
|
status: wait
|
|
priority: low
|
|
depends_on: [FLEX-WP-0040-T05, FLEX-WP-0039-T01]
|
|
```
|
|
|
|
Wait: FLEX-WP-0039 readiness surface and a founder rollout decision for a pin
|
|
serving the pack, with the executor's declared fail-closed stance. Gate:
|
|
founder-approved rollout; no live change from this repo's agents.
