Possibility Reserve Architecture
A possibility is not identical to its outcome under one state.
An architecture by John Brajer, originated August 20, 2026.
Governing problem
Search and decision systems can destroy future value when they treat a poor result under present conditions as permanent evidence against the underlying possibility. Possibility Reserve preserves negative evidence without converting local failure into global erasure.
evaluate(possibility, conditions) → result
A failed result updates the record for that possibility under those conditions. It does not, by itself, justify declaring the possibility permanently dead.
The protected spine
1. Conditional Failure Memory
Failure attaches to state and conditions, not permanently to the possibility. The record preserves what was tried, what failed, why, and what condition changes would make reconsideration rational.
2. Graded Dormancy
Low-priority possibilities can lose active compute without being deleted. DORMANT is a resource-allocation state, not a synonym for DEAD.
3. Causal Reactivation
Relevant changes to dependencies or world state wake affected dormant possibilities for re-evaluation. Reactivation follows causal links rather than indiscriminately reopening the entire reserve.
4. Path-Expansion Search
A branch can earn exploration because of the valuable future possibility space it exposes, not only because it appears most likely to be the immediate final answer.
Lifecycle
DISCOVERED → ACTIVE → EVALUATED → ACTIVE / UNCERTAIN / DORMANT / ARCHIVED / INVALIDATED
The exact labels are replaceable. The non-negotiable distinction is semantic: temporary non-priority must remain different from permanent invalidation. Dormant possibilities retain reactivation conditions and provenance.
Reference record
A minimal implementation can retain identity, state, condition snapshots, evidence for and against, conditional failure records, dependencies, reactivation conditions, related possibilities, immediate value, information gain, Path Expansion, cost, risk, and provenance.
The schema is intentionally a reference interface rather than a frozen database contract.
Relationship to adjacent methods
Perspective Expansion changes the model so more materially relevant possibilities can become visible.
Possibility Reserve preserves condition-sensitive access to possibilities across time.
Path Expansion evaluates actions partly through the desirable future states they unlock; Path-Expansion Search applies that principle to exploration allocation.
BRMFA can inspect the mechanisms and dependencies that explain dormancy, failure, and reactivation.
Validation boundary
The August 20 source establishes the four-mechanism spine and the v0.1 architecture name. This publication formalizes lifecycle semantics, interfaces, and a validation program around that spine.
v0.1 does not claim superior performance over established search, optimization, or reasoning methods. Comparative advantage remains an empirical question to be tested under fixed budgets and changing environments.
Validation program
- Measure whether condition-linked reactivation recovers valuable opportunities permanent pruning misses.
- Measure whether graded dormancy lowers compute relative to keeping every branch active.
- Compare causal reactivation with periodic full reconsideration for irrelevant retry rate.
- Test whether Path Expansion improves discovered reachable value under a fixed exploration budget.
- Check whether failure memory prevents repeated attempts under materially unchanged conditions.
Provenance
John Brajer formalized Possibility Reserve Architecture v0.1 on August 20, 2026. The originating record fixed Conditional Failure Memory, Graded Dormancy, Causal Reactivation, and Path-Expansion Search as the protected spine. The September 12 publication formalization preserves that spine while making the lifecycle, interfaces, validation boundaries, and adjacent-framework relationships explicit.
