## Goal
Separate what a runbook is (characteristics), how far it can be trusted (maturity, earned and bound to a
pack revision), and what state an environment is in (projects). Replaces the environment-dependent
`exercise_status`. Model and candidate terminology: `docs/maturity-and-projects.md`.
## Decide the terminology and model
```task
id: RBT-WP-0008-T01
status: done
priority: high
state_hub_task_id: "904939c5-ed69-53a0-8fe1-2a0ae6d5337d"
```
Decided 2026-09-29 (Bernd: go with the suggestions, keep *project*): `docs/maturity-and-projects.md`.
## Idempotency as a declared characteristic
```task
id: RBT-WP-0008-T02
status: done
priority: high
state_hub_task_id: "911ef051-ee55-5c65-b134-57fa9f1fddce"
```
Done 2026-09-29: `idempotent: idempotent | non-idempotent | conditional` (+ `idempotent_note`) per step in the v0.2
schema, validator rule for `conditional`, derived runbook value (`flow.pack_idempotency`), declared honestly in the
showcase. Values are words because YAML reads unquoted yes/no as booleans. Follow-ups: show it in the UI, and use
it for the retry policy (T07).
## Bind runs to a pack revision
```task
id: RBT-WP-0008-T03
status: done
priority: high
state_hub_task_id: "a79e5b3d-221b-5ac6-a7a1-44737139c8f3"
```
Done 2026-09-29: `pack.digest()`; every run records `pack_digest` and `context` (project, target, environment class).
## Derive maturity from run history
```task
id: RBT-WP-0008-T04
status: done
priority: high
state_hub_task_id: "53fe81cd-6b67-5508-bdbd-38073a0d77e7"
```
Done 2026-09-29: `rtut/maturity.py`, review records (`REVIEWS.yaml`, bound to a revision), `rtut maturity`, `rtut review`.
`proven` = reviewed + rehearsed + clean in two environments by two operators. Not yet done: retiring `exercise_status` and the
"Record pack as exercised" click in the UI (T09).
## Project specification and shared datapoints
```task
id: RBT-WP-0008-T05
status: done
priority: high
state_hub_task_id: "d022c7fb-1421-5738-a00f-5b18593fb1a2"
```
Done 2026-09-29: attribute sets (`attribute-set/v0.1`: composition with `extends`, requirement, derived state, provenance,
`modified` flag), projects with targets and members (`project/v0.1`), project templates (`project-template/v0.1`),
`rtut/attrs.py`, `rtut/project.py`, schemas, CLI (`rtut project ...`), examples under `attribute-sets/` and `project-templates/`.
Runs started from a project take the resolved attributes as defaults and record the project as context.
## Project state
```task
id: RBT-WP-0008-T06
status: done
priority: medium
state_hub_task_id: "41f2b781-3699-5d21-bdfd-4ff3c2c0b777"
```
Done 2026-09-29: `project.state()`: member status `not-applied | applying | applied | stale | failed`, project state
`planned | applying | applied | stale`, plus the members that can start next (`after`) and the attributes still needed.
## Retry policy for non-idempotent steps
```task
id: RBT-WP-0008-T07
status: done
priority: medium
state_hub_task_id: "8b34c57b-3380-5f7b-aaf5-6227a47dcf60"
```
Done 2026-09-29: `run2.retry(..., acknowledge_partial=True)` is required unless the step is declared `idempotent` (undeclared
counts as not idempotent); the UI asks with a checkbox; the acknowledgement is recorded on the step. v0.1 runs have no idempotency
declaration and keep their free retry.
## UI for projects, maturity and attributes
```task
id: RBT-WP-0008-T08
status: done
priority: high
state_hub_task_id: "913c46fa-7790-5d32-ada1-8dec430d4ff5"
```
Done 2026-09-29 (tested over HTTP, not yet reviewed in a browser): the runbook list shows maturity per runbook; the front page lists
projects (environment, state, goal) and templates; a template page shows every attribute with requirement, note and source and
creates a project; the project page shows goal, state, still-needed attributes (fillable, validated against the runbooks that
consume them), members with status, maturity, next member and a Start run button, and per-member attribute tables with state,
source, modified mark and problems; runs started from a project take its attributes and link back to it; the pack page shows
maturity evidence, idempotency and a review form. Not covered: walking v0.2 runs (RBT-WP-0004). Original scope: show maturity and idempotency next to each runbook; a project view (goal, targets, member status, next member, needed
attributes with state, source and modified marks); start a run from a project so its attributes fill the form; a
template picker that instantiates a project.
## Retire exercise_status
```task
id: RBT-WP-0008-T09
status: done
priority: medium
state_hub_task_id: "54749c4e-69d8-54ee-a1f7-5e9f781a9053"
```
Done 2026-09-29 (RBT-WP-0009-T01): the click, `apply_exercise` and `exercise_update` are removed, the field is deprecated and ignored, and the shipped packs no longer carry it.
Original scope: replace the "Record pack as exercised" click and the `exercise_status` field with derived maturity; migrate the packs.
## Templates as products: auto-confirm and auto-pilot on a project
```task
id: RBT-WP-0008-T10
status: done
priority: medium
state_hub_task_id: "917961d5-1571-52a5-b138-a15163176ed4"
```
Done 2026-09-29: `rtut/projectrun.py` and `rtut/ui_projectrun.py`. A project run snapshots the resolved attributes, then runs the members
member by member in `after` order. Manual: you start each member (out of order needs a recorded override). Auto-confirm: the engine starts
the next ready member, ticks its run, closes it when it finishes cleanly, continues through push-through, and stops wherever a person is needed
(v0.1 member, manual-only or irreversible step, failed check). Closing locks and seals it, and abandons an open member run. Auto-pilot with
execution remains RBT-WP-0006. Attribute states to explore in use: needed, optional, modified,
checked; add what real use shows.
## Acceptance Criteria
- "Exercised" has a precise, environment-aware meaning; a production project is never called "exercised".
- Maturity is derived from runs, bound to a revision, and expires when the pack changes.
- A value shared by several runbooks is entered once, in the project.
