memory_reflection: PlannedFeature

Memory-reflection (v0.7.0): planned-feature object. Was a bool before the v0.6.3.1 P1 honesty patch; an object now so operators can tell “feature exists but disabled” apart from “feature not in this build”.

v0.7.0 recursive-learning ship (issue #655). The flag is { planned: false, version: "v0.7.0", enabled: true } because the underlying primitive landed across Tasks 1-6 on feat/v0.7.0-recursive-learning:

• Column (Task 1/8, commit f5d8a9e) — memories.reflection_depth INTEGER NOT NULL DEFAULT 0, first added in the recursive-learning schema bump (column inventory lives in docs/MIGRATION_v0.7.md; the current CURRENT_SCHEMA_VERSION is 53 in lockstep on both sqlite and postgres ladders as of v0.7.0 — v48 added federation_push_dlq (#933), v49 added 14 nullable archived_memories columns (#1025), v50 extended agent_quotas PK with namespace (#1156), v51 added federation_nonce_cache (#1255 / PR #1296), v52 added transcript_line_dedup (#1389 L4 / RFC-0001), v53 scoped the memories_au FTS5 sync trigger to (title, content, tags) only (R5.F5.2 / #1418)). Memory::reflection_depth: i32 with #[serde(default)] for wire-compat with pre-v0.7.0 federation peers.
• Governance field (Task 2/8, commit 630a6db) — GovernancePolicy.max_reflection_depth: Option<u32> (per namespace, JSON metadata, no schema bump). Accessor effective_max_reflection_depth() -> u32 returns the compiled default 3 when unset; Some(0) is the documented kill-switch.
• Relation (Task 3/8, commit b51a3f3) — reflects_on joins the canonical VALID_RELATIONS set; directionality matches derived_from (reflection is source_id, original is target_id); db::find_paths walks it without further work.
• MCP tool (Task 4/8, commit 3dc76f3) — memory_reflect (Family::Power, tool count 51 → 52). Atomic insert of a reflection memory + N reflects_on link writes inside a single BEGIN IMMEDIATE / COMMIT transaction. Postgres parity via inherent PostgresStore::reflect.
• Error variant (Task 4/8) — MemoryError::ReflectionDepthExceeded { attempted: u32, cap: u32, namespace: String } → HTTP 409 CONFLICT, code REFLECTION_DEPTH_EXCEEDED.
• Hook events (Task 6/8, commit fbf093c) — HookEvent::PreReflect (decision-class, EventClass::Write, 5s deadline, fires before the depth-cap check, Deny vetoes via ReflectError::HookVeto) + HookEvent::PostReflect (notify-class, EventClass::Write, 5s deadline, fires after COMMIT). Pipeline event count 21 → 23.
• Audit chain (Task 5/8, commit c61a05b) — every depth-cap refusal appends a reflection.depth_exceeded row to the append-only signed_events audit table under a canonical-CBOR payload + SHA-256 payload_hash + attest_level = "unsigned". Content body is deliberately omitted (PII guarantee); hook vetoes are NOT audited by this row (caller-policy refusals carry their own provenance).

The v1 wire-shape projection collapses this object back to a single bool (via Capabilities::to_v1), so pre-v0.6.3.1 clients that pinned the v1 schema continue to see the same boolean field at the same path (and now read true).

embedder_loaded: bool

v0.6.2 (S18): runtime-observed embedder state. semantic_search above reflects configured capability (derived from the tier’s embedding_model setting). embedder_loaded reflects actual state after Embedder::load() attempted to materialize the HuggingFace model on startup. When an operator configures the semantic tier but the model download or mmap fails (offline runner, read-only fs, missing tokens), semantic_search=true would mislead. This flag exposes the truth so setup scripts can assert the daemon is actually ready for semantic recall before dispatching scenarios. Default false; populated by handle_capabilities when the HTTP/MCP wrapper hands in the live embedder handle.

recall_mode_active: RecallMode

v0.6.3.1 (P1 honesty patch): runtime recall-mode tag. Reflects the live embedder + LLM availability, not the configured tier. See RecallMode.

reranker_active: RerankerMode

v0.6.3.1 (P1 honesty patch): runtime reranker-mode tag. Reflects the live CrossEncoder variant. See RerankerMode.

reflection_boost: ReflectionBoostReport

v0.7.0 L2-8 — reflection-aware reranker boost configuration. boost = 1.0 means the boost is disabled and the reranker reproduces its pre-L2-8 behavior. Default (1.2) is the value the daemon ships with; operators can inspect this to verify the live boost matches their configured policy. Skipped from the wire when serialising a pre-L2-8 default so older capabilities consumers round-trip cleanly.
