Add TREV-WP-0012/0013/0014: modeling pass + spun-out implementation gaps

TREV-WP-0012 is the modeling-only workplan requested after using the
Control Plane UI surfaced real gaps: Phase registration has no
structured repo/provenance fields, the ledger URI is hand-typed, and
degeneration policies are opaque ids with no reviewable spec behind
them. It produces a use-cases document and a discussable spec addendum
before any schema/UI implementation.

Two of the use cases uncovered while scoping this turned out to be
bigger than documentation gaps and are tracked as their own workplans
per that direction: TREV-WP-0013 (nothing currently computes or writes
Remission Credit ledger entries at all) and TREV-WP-0014 (Extension
Registry, Breach Record, and Conversion Attestation backends already
exist from WP-0006 but have no Control Plane UI).

# Phase provenance, ledger reference, and degeneration-policy modeling
Triggered by using the Control Plane UI for the first time (WP-0009-T04):
the Phase registration form asked for a bare `source_revision` with no
repo attribution, a hand-typed `ledger` URI, and an opaque
`degeneration_policy` id with no way to see what it actually specifies.
These aren't UI bugs — the Phase Manifest schema
(`schemas/phase_manifest.schema.json`) itself doesn't yet carry the
structure the UI would need to show any of this properly, and FR-11
(Successive Phases, `specs/ProductRequirementsDocument.md`) already commits
the framework to base-release/prior-Phase provenance that the schema has
never modeled either.
This is a **modeling-only** workplan: it produces documents (a use-cases
spec and a discussable spec addendum) and decisions, not schema or UI
changes. Implementation follows in later workplans once the addendum is
reviewed (T05).
```task
id: TREV-WP-0012-T01
status: todo
priority: high
```
**Write the use-cases document**, as its own spec file (not folded into
`specs/PhaseManifestSpecification.md`) — working title
`specs/PhaseLifecycleUseCases.md`. Cover, systematically, at minimum:
1. First Phase ever declared for a repo (the three real pilot candidates:
`net-kingdom`, `railiance-vergabe-teilnahme`, `info-tech-canon`).
2. A successive Phase on a repo that already had an earlier, converted
Phase (FR-11) — including what "base release" means when the prior
Phase's Milestone Release is itself the base.
3. Operator registers a Phase; Contributor proposes a Development Credit;
Operator/Admin reviews (already built, WP-0009 — include for
completeness/cross-reference, not to redesign it).
4. Remission Credit accrual over time under the active degeneration
policy — note as an open gap for WP-0013, not solved here.
5. Conversion Event fires, Attestation published — note as a UI gap for
WP-0014.
6. Monetization Extension registration and canonical-status review — note
as a UI gap for WP-0014.
7. Breach/Compliance Record publication — note as a UI gap for WP-0014.
8. A second Licensor tenant besides `binky` onboards.
9. An external auditor verifies a Phase's evidence package offline,
without needing to trust or even reach the Control Plane UI (FR-8/FR-9
— call out explicitly that this use case has *no* UI surface by
design, so it doesn't get silently forgotten as "not yet built").
```task
id: TREV-WP-0012-T02
status: todo
priority: high
human_accept_required: true
```
**Decide repo identification and Phase-provenance fields (human gate).**
Per direction already given: identity rests on the Forgejo instance
("home hub") plus the repo's own stable id within that instance, *and*
the Forgejo service URI and repo name are also retained (not derived) —
so a rename or instance move stays repairable rather than silently
breaking a Phase's provenance link. Concretely decide and record:
- Field names/shape for `milestone_release`: a hub identifier, a
Forgejo-internal repo id, the Forgejo service URI, and the repo name
(owner/repo slug) — four values, not one string.
- Whether this is required or recommended for Stage 0 (precedent:
`longstop_at` moved from recommended to required under a working
default, `specs/OpenQuestions-WorkingDefaults.md` Q8).
- How a successive Phase (use case 2 above) references its base — a
`trsl:phase:...` id, and what a first-ever Phase puts there instead
(null, or an explicit "no prior Phase" marker — decide which is
cleaner for fold/validation logic downstream).
- Whether any of this is retroactively backfillable for the three
existing pilot-candidate example manifests, or only required going
forward.
```task
id: TREV-WP-0012-T03
status: todo
priority: high
human_accept_required: true
```
**Decide the degeneration-policy / calculation-model spec-file
convention (human gate).** Per direction already given: every policy or
calculation model (this includes the Development Effort Calculator's own
Candidate A formula, `specs/DevelopmentEffortCalculatorConcept.md`, not
just degeneration policies) corresponds to a markdown specification file
with a simple, distinct name, an id, and a revision — built on git's own
mechanisms (commit hash and/or file path, no new versioning
infrastructure). Concretely decide:
- Where these spec files live (likely already `specs/*.md` — decide
whether a dedicated subdirectory or naming convention is needed so a
policy id like `trsl:policy:linear-longstop-v0` maps unambiguously to
one file).
- What "id and revision, built on git internals" means precisely — e.g.
the policy id embeds the file path and a pinned commit hash, or the
file's own frontmatter carries an id/revision pair that a human commits
to alongside code changes (check how `the-custodian`/state-hub already
present read-only reference-documentation views linked by id, per the
user's explicit steer to reuse that pattern rather than invent a new
one, and follow whichever mechanism is actually in use there).
- How the Control Plane UI links a policy id shown next to a Phase to a
**read-only** rendered view of that spec file — no in-UI editing,
consistent with every other governance-action pattern in this project.
- Whether this same convention should also cover the six canonical
monetization profiles (`specs/CanonicalMonetizationProfiles.md`) for
consistency, or is scoped to degeneration policies and calculators only
for now.
```task
id: TREV-WP-0012-T04
status: todo
priority: medium
human_accept_required: true
```
**Decide the ledger's UI treatment (human gate).** Per direction already
given: keep the `ledger` field in the schema — not as something the
standard Phase view surfaces, but as an internal reference reachable only
via an explicit drill-down/details action. This is intentional groundwork
for eventually supporting more than one ledger per Phase (federation,
`specs/ProductRequirementsDocument.md` NFR-3), not just a display
preference. Decide:
- What the drill-down actually shows (the raw ledger URI/reference plus a
link to `GET /phases/{id}/ledger`'s live data, or something more), and
where it lives in the Control Plane's navigation (a "details" link on
`phase_detail.html` rather than a top-level field).
- Whether the Phase registration form still needs a `ledger` input at
all going forward, or whether the Trust Service should compute/assign
it automatically now that it is always the ledger's host in Stage 0 —
distinct from the schema question of whether the field stays.
```task
id: TREV-WP-0012-T05
status: todo
priority: high
```
**Draft the spec addendum** reflecting T01T04's accepted decisions, for
review before any implementation — schema changes (`schemas/
phase_manifest.schema.json`), the policy-spec-file convention, and the
Control Plane UI changes it implies. Do not implement anything from this
task; it produces a reviewable document only. Once accepted, file the
implementation work as its own workplan(s), consistent with how WP-0009
and WP-0010 were split from a single combined plan.
## Related gaps spun out as their own workplans
Use cases 4, 6, and 7 above are bigger than a modeling exercise — they
are missing implementation, not missing documentation — and are tracked
separately rather than folded in here:
- `workplans/TREV-WP-0013-remission-credit-automation.md` — use case 4.
- `workplans/TREV-WP-0014-control-plane-extensions-breach-attestation-ui.md`
— use cases 5, 6, 7.
Use case 8 (second Licensor tenant onboarding) is judged small enough to
stay under `workplans/TREV-WP-0008-governance-and-pilot-rollout.md`
rather than warrant its own workplan — revisit that call if it turns out
to need real design work once a second tenant is actually on the table.

# Remission Credit automation (degeneration policy execution)
Spun out of `workplans/TREV-WP-0012-phase-provenance-and-policy-modeling.md`
(use case 4). Every Phase declares a `degeneration_policy`
(`trsl:policy:linear-longstop-v0` is the accepted v1 norm,
`specs/OpenQuestions-WorkingDefaults.md` Q7), which is supposed to
generate `remission-credit` Target Ledger entries over time when
Development Credit progress is insufficient (FR-6,
`specs/ProductRequirementsDocument.md`). **Nothing in this codebase
currently computes or writes these entries.** `fold.py` can consume them
if they exist; nothing produces them. This gap predates the Control Plane
UI work — it was never in scope for WP-0006 (Trust Service) or WP-0009
(Control Plane), and surfaced now only because reviewing the UI's
Phase-registration flow prompted a fuller look at what a Phase's lifecycle
actually requires end to end.
Blocked on `workplans/TREV-WP-0012-phase-provenance-and-policy-modeling.md`
T03's decision (how a policy id maps to its spec file) — the
implementation here should be checkable against that spec file, per the
user's explicit requirement that policy code and policy specification stay
verifiably in sync.
```task
id: TREV-WP-0013-T01
status: wait
priority: high
```
**Design the remission calculation and scheduling model.** `R(t) = T0 ×
clamp((t - t0)/(tL - t0), 0, 1)` (Q7) needs: a chosen recognition cadence
(daily/monthly UTC per Q7's own text), an idempotent
"has this period's remission already been recorded" check (ledger entries
are append-only — a re-run must not double-remit), and a decision on
where `t0` (Phase activation) comes from if it isn't already a manifest
field (registration time? an explicit `activated_at`?). Cross-check
against whatever `trsl:policy:linear-longstop-v0`'s spec file (once
WP-0012-T03 lands) says, rather than re-deriving the formula from Q7
prose alone.
```task
id: TREV-WP-0013-T02
status: wait
priority: high
```
**Implement and test** the calculation as a pure function (mirroring
`fold.py`'s determinism discipline) plus whatever writes the resulting
`remission-credit` entries into the hosted Target Ledger — a scheduled
job, an on-demand Control Plane action, or both. Decide which actor
"submits" these entries for attribution purposes (no human credential
naturally owns a policy-driven entry) and record that decision explicitly
rather than leaving `submitted_by_token` implicitly null.
```task
id: TREV-WP-0013-T03
status: wait
priority: medium
```
**Surface it in the Control Plane UI**: `phase_detail.html`'s Ledger
table already renders `remission-credit` rows generically once they
exist; verify that holds, and add a metrics-level explanation (e.g. next
scheduled remission date/amount) if `metrics.py` doesn't already forecast
one.

# Control Plane UI: Extension Registry, Breach Records, Conversion Attestation
Spun out of `workplans/TREV-WP-0012-phase-provenance-and-policy-modeling.md`
(use cases 5, 6, 7). Unlike `workplans/TREV-WP-0013-remission-credit-automation.md`,
the backend for all three already exists and is tested
(`registry.register_extension`/`promote_extension_canonical`,
`breach_record.publish_breach_event`/`get_breach_records`,
`attestation.publish_attestation`) — this is UI-only work, extending
`service/control_plane_app.py` and its templates the same way WP-0009-T04
did for Phases and the Ledger. Not blocked on WP-0012; can start any time.
```task
id: TREV-WP-0014-T01
status: todo
priority: medium
```
**Extension Registry UI**: a page listing registered extensions with
their `registered`/`canonical` status, a form to register a new extension
(any authenticated tenant, per `registry.register_extension` — confirm
whether Control Plane rights-gating applies here or whether extension
registration is intentionally open, since `control_plane.py` today has no
wrapper for it at all), and a canonical-promotion action restricted to
whatever rights tier canonicalization review actually requires (check
`specs/TargetRevenueControlPlaneConcept.md` §2's rights table — this may
need its own entry there if it's missing).
```task
id: TREV-WP-0014-T02
status: todo
priority: medium
```
**Breach/Compliance Record UI**: a form to publish a breach/compliance
determination against a Phase (`breach_record.publish_breach_event`),
respecting the anonymized-by-default / named-only-with-opt-in rule
(FR-10, License V1C1 §7.4), and a read view on `phase_detail.html`
listing a Phase's published records.
```task
id: TREV-WP-0014-T03
status: todo
priority: low
```
**Conversion Attestation UI**: read-only — a Phase that has converted
should show its Attestation (`attestation.publish_attestation` is
idempotent/publish-on-first-observation) on `phase_detail.html`, including
Future License and the supporting ledger checkpoint, rather than requiring
a caller to hit the Trust Service's `GET /phases/{id}/attestation`
directly to see it.
```task
id: TREV-WP-0014-T04
status: todo
priority: low
```
**Tests and docs**: Docker-gated `TestClient` tests for all three (same
pattern as `tests/test_control_plane_app.py`), workplan Result sections,
`README.md` row update.
