What this page is
This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.
Methodology
Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.
Content
Ordinary source-restoration note. In ordinary use, do not build a source dossier. The first useful note is:
encounteredSourceCandidate; work or reliance claim under repair; claim or effect needed; governing source needed; relation-governed move now; blocked overread; stop or reopen condition
The encountered source candidate may be a tile, credential view, approval-looking memo, generated explanation, copied review, provenance mark, API wording, functional-description publication, or composed source chain. The pattern asks whether the requested claim is currently carried by a project-side source named by value, not whether the source candidate is impressive, fluent, easy to inspect, or visually salient.
Conditional source-relation field set. Use the fuller fields below only when release, safety, compliance, role assignment, status, gate, assurance, contested source, external reliance, cross-context reuse, currentness, revocation, generated source relation, or copied source relation is being relied on for the claim under repair. These fields are local restoration aids, not a new record kind.
Start with the A.15.4 first restoration checks above when the encountered source candidate is about to guide a work move, reliance move, or work-relevant claim. If the issue under repair is only evidence, currentness, gate-passage claim, ConstraintValidity status, engineering justification, commitment, speech act, boundary wording, use-boundary wording, credential proof, source-status proof, explanation, comparison, or publication-carrier or front-end behavior, use the pattern governing that issue directly. Use A.15.4 only when source restoration is needed before role assignment, method, plan, work, work result, result measurement, or another work move or reliance move can proceed.
Authority-looking source-backed work or reliance case. Use A.15.4 when an approval-, permission-, gate-, command-, credential-, delegation-, revocation-, status-, provenance-, dashboard-, copied-review-, generated-explanation-, schema-, API-, or composed-chain case is about to be used as a work cue, reliance claim source, release-reliance claim source, performed-work evidence source, approval-claim source, approval-effect source, role-assignment-claim source, status-claim source, or next work-relevant move. The recognition moment is that an encountered publication, display, credential view, wording, or explanation looks like permission, prohibition, readiness, or evidence for starting work. The repair question remains: which work or reliance claim is being made, and which source is required for it?
Here "authority-looking case" is only a recognition phrase for the encountered situation. The governing source that permits, forbids, records, or carries the work-relevant claim may instead be a GateDecision, SpeechAct, U.Commitment, U.RoleAssignment, credential record, status record, A.6.B-claim being made, A.10 evidence path, or B.3 assurance claim. Use E.17:5.1c for the shared meanings of orientation use, reliance use, work claim, reliance claim, operative claim, unsupported downstream use, and reopen trigger; use E.17:5.1d when the primary question under repair belongs to another governing pattern.
The central behaviour is: name the work or reliance claim under repair, work-relevant P2W claim under repair, or P2W chain position under repair; name the source that carries the needed claim or effect; keep the U.Episteme or U.EpistemePublication distinct from publication form, MVPK face, publication carrier, rendering, and source-finding cue; choose the minimum sufficient next move; and do not raise the claim beyond the recovered relation, source relation, or recovered use boundary. If the named project record states the governing FPF relation, use that recorded relation directly rather than inferring it from wording.
Positive repaired disposition. An encountered U.Episteme publication, publication form, MVPK face, publication carrier, rendering, or source-finding cue may guide work or reliance only to the claim or effect carried by the recovered source, actor or role assignment, work or reliance claim under repair, work-relevant P2W claim under repair, or P2W chain position under repair, affected work target, context, window, and source-recoverable claim or effect. The repaired outcome is the smallest relation-governed work or reliance statement plus the unsupported work claim or reliance claim still blocked.
Reliance dispositions by recovered source relation:
A small A.15.4 restoration note is enough for the first disposition:
Borrowed episteme and publication discipline. A.15.4 borrows the C.2.1, E.17, and A.16.0 distinction rather than minting a new generic U.* kind. The claim-bearing FPF kind here is U.Episteme; U.EpistemePublication is used only when that episteme is available as a published episteme with MVPK-face references. Publication forms, MVPK faces, publication carriers, renderings, PublicationUnit instances, and source-finding cues are separate kinds or relation positions in the case. A planned baseline remains a U.WorkPlan or U.WorkPlanning plan record such as SlotFillingsPlanItem; launch values and finalization values remain their own project records, decision logs remain gate or decision records, performed-work evidence remains evidence, and dated work occurrences remain A.15.1 or U.Work matters.
When the required source is incomplete, choose one relation-governed source-restoration disposition after naming the work or reliance claim under repair, work-relevant P2W claim under repair, or P2W chain position under repair and the source required for that claim or effect; pick the lightest move that preserves practical work and source recoverability:
- Use the encountered source candidate only for orientation or source-finding.
- Reopen the required source
U.Episteme, sourceU.EpistemePublication, register entry, or governing source, or refresh status or currentness. - Narrow actor and role assignment, requested operation or work class, affected work target, affected resource, affected claim, context, and effective window until the recovered source really covers the move.
- Run a bounded reversible probe under an explicit
U.WorkPlanwhen no external-impact reliance is being made. - Ask the role assignment accountable for the issuer, gate decision, evidence path, role-assignment record, status record, or boundary claim set to expose or repair the missing source.
- Repair the
U.WorkPlan,U.MethodDescription, dashboard label, source link, or boundary wording that made the overread plausible. - Proceed only inside the recovered scope and window.
- Block only the work claim or reliance claim that lacks source relation.
