PRISM v2.8.0 released

[Ronkupper]

PRISM v2.8.0 is released — corpus-access dispatch Phase 2: the lens-anchored auto-trigger.

This is the consuming build that v2.7.0 promised. v2.7.0 shipped the recommended_sources: field on the lens schema and left a note that "auto-population of the corpus-access Envelope from this field is the consuming Phase-2 build that follows." That build is this one. No lens-schema or lint-catalog change — v2.8.0 only consumes the field shipped at v2.7.0.

What landed

• Recognition (automatic). A lens carrying a recommended_sources: entry is trigger-capable. Orchestration recognizes, on its own, the conjunction: the lens is in play, its material question is being actively worked, and a recommended source's answers: binding matches that question. Recognition is the only step that becomes automatic.
• Dispatch (advisory; operator-ratified). Recognition produces a candidate, not a dispatch. Orchestration shapes the investigation-posture Envelope and surfaces it for ratification — the operator ratifies, edits, or skips, and silence does nothing. SP-9 ("silence is never consent") is preserved by keeping the autonomy in the recognition and never the dispatch; the trigger reuses the existing propose-then-ratify (P0→P1 Layer-3) posture and introduces no new consent model.
• Auto-populate. The matched source record auto-populates the Envelope's mandatory Source framing and Temporal frame caveats — the two fields Phase 1 made mandatory-but-hand-written — so the caveat is structurally impossible to silently omit. The outbound caveat now travels automatically, closing the self-containment loop.
• Candidate logging + noise guard. Surfaced-but-unratified candidates are What's next material, not Dispatch-register entries. The guard surfaces once per {lens, source, material-question} per engagement, records a decline, and re-surfaces only on a material change to the question — the saturation predicate three-layer readiness already uses for Library coverage.

Additive and backward-compatible: engagements not using the trigger are unaffected. PRISM-LINT-08 remains reserved.

Phase status

• Phase 1 (v2.6.0) — manual and vendor-executed paths, manual invocation.
• Phase 2 (this release) — lens-anchored auto-trigger.
• Phase 3 — cowork-mcp auto-driven authenticated-session lookup; reserved, gated on the Cowork substrate maturing.

Calibration / report-back

• Trigger precision — how often recognition surfaces a genuinely useful candidate vs. noise across real engagements; the material-question match heuristic is rev. 1.
• Noise-guard granularity — whether once-per-{lens, source, material-question} with material-change re-surface over- or under-surfaces in practice.
• Auto-populate fidelity — whether the source-record framing:/recency: text reads well as Envelope caveats verbatim, or wants per-dispatch tailoring.
