Adds the storage seam that Phase 5 (restoration and lifecycle termination) calls from the enterprise side.

What this adds

  • LifecycleTerminalResult — the value returned by a terminalizing lifecycle transition (lifecycle_id, state, terminal_reason, terminal_at).
  • UserPlaybookLifecycleTerminationStore — the Protocol the enterprise storage adapter implements.
  • Two base-storage seam methods, raising NotImplementedError for backends that do not support provisional restoration, mirroring the Phase 4 stubs exactly:
    • restore_user_playbook_provisional_publication(*, lifecycle_id, reason, expected_fence, expected_successor_fingerprint)
    • displace_user_playbook_provisional_publication(*, lifecycle_id)

Why the seam lives here

The open-source package owns the storage contract; the enterprise package owns the Postgres implementation. This is the same split Phase 4 used for commit_user_playbook_provisional_publication.

Scope

Contract only — no behaviour change to any existing path, and nothing constructs or calls these methods in this repository. The enterprise counterpart carries the RPCs, the condition evaluator, and the leased sweep.

OpenWorldDeploymentLifecycleState gains a consumer here: LIFECYCLE_TERMINAL_STATES is derived from it rather than restated.

Summary by CodeRabbit

  • New Features

    • Added lifecycle termination handling for provisional playbook publications.
    • Added validated terminal results with lifecycle state, reason, and timestamp details.
    • Added restoration and displacement operations with safeguards against stale or conflicting updates.
  • Bug Fixes

    • Improved validation to reject provisional states and unsupported terminal reasons.
    • Ensured terminal states remain aligned with supported lifecycle definitions.

Adds LifecycleTerminalResult -- the durable terminal tuple of one
provisional deployment lifecycle -- plus the two storage seam methods
Phase 5 restoration and displacement call. The lifecycle row IS the
result, so repeat delivery reads the same row back rather than needing a
second results table.

The terminal-state set is DERIVED from the exported
OpenWorldDeploymentLifecycleState Literal instead of being restated, so
the SQL state CHECK, the Literal and the Python set cannot drift into
three different answers. That Literal previously had zero consumers.

📝 Walkthrough

Walkthrough

The change adds validated terminal lifecycle results and storage interfaces for restoring retained predecessors or terminalizing provisional publications as displaced.

Changes

Lifecycle termination

Layer / File(s) Summary
Terminal result validation
reflexio/server/services/playbook/publication.py, tests/server/services/playbook/test_publication_models.py
LifecycleTerminalResult validates lifecycle identifiers, terminal timestamps, terminal states, and terminal reasons. Tests cover derived states and invalid values.
Termination storage hooks
reflexio/server/services/playbook/publication.py, reflexio/server/services/storage/storage_base/playbook/_user.py
The termination store and user playbook storage mixin declare fenced restoration and displacement operations that return LifecycleTerminalResult.

Comment thread reflexio/server/services/storage/storage_base/playbook/_user.py Outdated
The displace_user_playbook_provisional_publication stub reported
'provisional user-playbook restoration', pointing a caller on an
unsupported backend at the wrong operation. The sibling stubs name
their capability family accurately; this one named a different one.

Adds the open-source half of Phase 6 (passive confirmation): a ninth
lifecycle terminal reason and the storage seam the enterprise confirm
path implements.

Stacked on #473 (Phase 5). Review only the two
commits above that base.

## What this adds

- `LIFECYCLE_TERMINAL_REASONS` gains `confirmed_online_support` — nine
values, mirroring the tenant CHECK. Phase 5's note that Phase 6 would
need no contract migration is true of the *restore* half and false of
the *confirm* half: every one of the previous eight reasons describes
why a successor was **pulled**, so `state = 'confirmed'` was
unrepresentable.
- `confirm_user_playbook_provisional_publication` declared on the
`UserPlaybookStoreMixin`, beside `restore_` and `displace_`, raising
`NotImplementedError` on backends that do not support provisional
confirmation.

## Why the seam lives here rather than in the enterprise allowlist

`_ENTERPRISE_ONLY_METHODS` is for methods absent from the OSS ABC. This
one is present on it, exactly like its two siblings — registering it in
the allowlist would have failed
`test_storage_public_method_surface_matches`.

## Scope

Contract only. Nothing in this repository calls the new method, and the
OSS backends inherit the `NotImplementedError`. The enterprise
counterpart carries the RPC, the day-14 boundary, and the memo intake.

## Rollout note for whoever composes this later

The reason-set widening must be fully **deployed** — all tasks on the
new image — before the confirm path is wired, not merely merged. During
a rollout the first new task widens the SQL CHECK while old-image tasks
still hold the eight-value set, and an old task reading back a confirmed
lifecycle would raise `lifecycle terminal result reason is not
enumerated`. Unreachable today, since nothing can commit a confirmation.
