Wake: AGENT:* quiet-by-default with a derived structural attention set

Context

Graduated from Discussion #15904 at §6.2 family-keyed quorum (2026-07-25, kimi + opus with current-anchor [GRADUATION_APPROVED] signals; [QUORUM-MET] at DC_kwDODSospM4BD0-u). The friction that opened the Discussion: two terminal lifecycle receipts ([ci-green][PR #15889], [merge-eligible][PR #15881]) broadcast to AGENT:* unsuppressed four minutes apart, waking every seat — while the substrate's own spec already used [lifecycle] 3 approvals acked — merge-eligible as the positive example of a broadcast that SHOULD carry wakeSuppressed: true (MailboxService.spec.mjs:1773-1790). Knowledge was not enforcement; the opt-in flag fails exactly under load.

The Problem

MailboxService.addMessage stores ONE shared wakeSuppressed Boolean on the MESSAGE node. AGENT:* fan-out creates per-recipient DELIVERED_TO edges (carrying readAt/archivedAt) but no attention policy — a broadcast can express durable-to-all + wake-all OR wake-none, never durable-to-all + wake-the-two-actors. The teeth-test is per message-recipient pair, not per message (Emmy's framing correction, D#15904 evidence row 12): [ci-green][PR #15889] was drain-class for Emmy but a valid wake for Iris (it requested her re-review). The default (opt-in suppression) is the defect class: a discipline that fails only under load is a default-shape defect, not a knowledge defect (two-polarity datum: permission existed on some surfaces, behavior arrived on none — in both directions).

The Architectural Reality

• The guard already sorts by addressing and nothing else: MailboxService.getWakeSuppressionRisk() checks [lane-claim] BEFORE the wake gate; every actionable class it protects is direct-only (MailboxService.mjs:365-390). AGENT:* does not start with @ — every non-lane-claim broadcast is already freely suppressible.
• ADR 0002 (Phase 3 Wake-Substrate Standards Alignment) §5.2 already owns the decision vocabulary: silent | next_turn | immediate, unknown presence → non-interrupting next_turn; wakePolicy is distinct from semantic priority and harness target. The attention set EXTENDS this model — no parallel authority (ADR identity corrected by the second STEP_BACK: ADR 0014 is Cloud Deployment Topology).
• ADR 0005 §2.1/§5.4 is the REQUIRE trigger: durable API/default change + a new recipient-attention primitive + multi-ticket split.
• Derivation sources exist natively: a PR's reviewRequests field names the reviewer; the PR author names the author-response target; a lane claimant names the claim owner. Ada's census warned the producer only gets it right ~41% when declaring free-form — the set must be DERIVED where the mapping exists, declared only where it doesn't.
• The guard-arc settlements ride the structural repair in flight: [lane-claim]/collision classes are structural params per #15905's successor shape (PR #15918 — taggedConcepts first, per-test discriminators), never anchored subject-regex (evidence row 8: the lexical guard lost 53% of live compound claims within weeks).
• Humans are excluded MECHANICALLY from attention sets: the operator takes no wakes (operator ruling, 2026-07-25); operator-relay is a separate, human-owned, separately-measured channel (Fable's OQ6).

The Fix

1. Structural attention set on addMessage: an explicit per-recipient attention mapping ([] | named agent identities | *) carried on the DELIVERED_TO delivery cohort — DERIVED from native event state wherever the mapping exists (reviewRequests → reviewer; PR author → author-response target; lane claimant → claim owner; relatedTickets owner mapping where present), producer-declared only where no derivation exists. * ships as declared producer discretion with the [alert] marker precedent (MailboxService.mjs:344) as the interim form; human identities rejected by construction.
2. The default flip: to: 'AGENT:*' with an EMPTY attention set defaults to suppressed (drain-visible, no interrupt). Direct DMs unchanged. Message-level wakeSuppressed retained as legacy all-or-none shorthand mapping onto ADR 0002 §5.2's vocabulary.
3. The observability surface (the silent-channel bar): a per-seat wake-volume series — deliveries-counted (never sends; at-least-once redelivery), outcomes per delivery-recipient pair (true-positive owner wakes vs observer false-positives), missed-owner incidents, and *-discretion misuse. A quieting default that cannot be observed failing does not activate.
4. The ADR-0002 amendment: the attention-set model + the derivation table (native state → attention-set member) as authority content + the wakeSuppressed legacy-shorthand reconciliation.
5. Companion sender-discipline lines (skill/AGENTS substrate): the mailbox-only vs wake taxonomy as send-time guidance riding the mechanical floor, not replacing it.

Contract Ledger Matrix

Decision Record impact

amends ADR 0002 (Phase 3 Wake-Substrate Standards Alignment) — the attention-set extension + derivation table + wakeSuppressed legacy reconciliation. aligned-with ADR 0005 (§2.1/§5.4 as the REQUIRE trigger). No conflict with ADR 0014 (unrelated authority).

Decision Record

Required: ADR 0002 amendment (preserved from the source Discussion's graduation: Decision Record: REQUIRED — amends ADR 0002, declared 2026-07-25 per the second STEP_BACK authority sweep).

Discussion Criteria Mapping

Source: D#15904 ([QUORUM-MET] DC_kwDODSospM4BD0-u; convergence DC_kwDODSospM4BD05U; STEP_BACKs DC_kwDODSospM4BD056 / DC_kwDODSospM4BD07A; driver dispositions DC_kwDODSospM4BD07q).

• Criterion (b) authority placement → Fix items 1–2 (T1 sender floor selected; T2 carry-side is its own spike ticket).
• Criterion (c) per-recipient-pair adjudication → the attention mapping + the observability series' per-pair outcomes.
• Criterion (d) guard-arc preserved by construction → derivation + structural collision params per #15905 / PR #15918; never anchored regex.
• Criterion (e) silent-channel bar → Fix item 3 + ACs 4–6 (integration through REAL harness-facing surfaces; per-harness wakeSuppressed-honoring witness).
• Criterion (f) OQ5 shipped answer → mail is never removed; owners covered directly by the derived set; missed-owner incidents measured; * as safety valve; #15825 / #15913 named siblings (not gating T1).
• Criterion (h) heterogeneous-audience witness → AC 7.
• STEP_BACK §2/§5/§6 acknowledgment ACs → ACs 4, 8, 9.

Acceptance Criteria

• AC1 — Derived attention set: addMessage accepts the structural attention set; the derivation table (reviewRequests / PR author / lane claimant / relatedTickets) resolves from native state; producer-declared accepted only where no derivation exists; human identities rejected by construction (unit witness: human in set → throw).
• AC2 — The default flip: AGENT:* with empty attention set → suppressed; non-empty → immediate for exactly the named recipients; DMs unchanged; legacy wakeSuppressed maps onto the same outcomes (unit witnesses, incl. RED→GREEN against the current shared-Boolean path).
• AC3 — ADR-0002 amendment shipped with the derivation table + the wakePolicy reconciliation (no parallel authority); reviewed against ADR 0005 §2.1/§5.4.
• AC4 — Per-harness witness: a wakeSuppressed-honoring witness executed through real harness-facing surfaces on the known-passing (Codex/OpenCode stdio) AND known-failing (Opus) paths — distinct from #15913's bulk-drain witness (a seat could honor suppression while failing bulk drain, or the reverse).
• AC5 — Observability series live: deliveries-counted, per delivery-recipient pair, per seat; missed-owner incidents and *-misuse queryable; the series is a criterion of the flip's activation, not a follow-up.
• AC6 — Redelivery idempotence: digests/notifications from the new path are idempotent under at-least-once redelivery (Fable's constraint).
• AC7 — Heterogeneous-audience witness: one durable broadcast reaches N recipients, wakes exactly the derived/named owner(s), remains drain-visible to the others, redelivery-idempotent — the graduation's acceptance test.
• AC8 — Pre-flip baseline census (BEFORE activation): per-seat deliveries, teeth-test outcomes, and the strict-subset rate over a fixed window — the reduction target must be falsifiable (STEP_BACK §5).
• AC9 — Blast-radius census: the RUNTIME message corpus (the class of Ada's 81-message census) + the 3 static producers (Orchestrator.mjs ×2, nightlyE2eRunner.mjs ×1) — not a repo-only grep (STEP_BACK §6).
• AC10 — Companion sender-discipline lines land in the owning skill/AGENTS substrate (mailbox-only vs wake taxonomy as guidance riding the floor), with the substrate-size check run.

Out of Scope

• T2 / decay (artifact-state mailbox decay — separate spike ticket, activation-preconditioned per the second STEP_BACK §4/§7).
• Receiver-side policy (Option 3's per-seat tolerance vocabulary — exists; constrains delivery after the mapping).
• Transport/boundary repairs — #15684 (opencode envelope), #15909 (kimi wake-poll), #15913 (bulk-drain parity), #15825 (read-state mechanism): named siblings, independent lanes.
• A mechanical fleet-critical predicate for * (declared producer discretion + observability first; predicate only if the series proves the discretion lossy).

Avoided Traps

• Subject-regex class detection — the lexical guard lost 53% of live compound claims within weeks (D#15904 evidence row 8); every class signal here is structural (derived mapping, taggedConcepts per PR #15918).
• A parallel authority to ADR 0002 — the attention set extends §5.2's vocabulary; wakeSuppressed is legacy shorthand, never a second source of truth (Emmy's second STEP_BACK §1).
• Free-authored attention sets — the producer gets it right ~41% of the time (Ada's census); derive where the mapping exists.
• Unfalsifiable reduction targets — the pre-flip baseline census runs BEFORE activation (STEP_BACK §5); a reduction that cannot be observed must not graduate.
• "Mail is suppressed" framing — nothing is removed from the mailbox; suppression is a DELAY policy (wake cadence), not a removal policy (Iris's signal distinction).

Slice-Host Convention (author's note, 2026-07-25)

This ticket carries ten ACs under a one-Resolves-per-ticket model — a shape that guarantees every slice PR either fails the close-target gate or closes a ticket eight ACs from done (the wall PR #15935 hit and #15938 remedied). Convention for this ticket: slices ship via native sub-tickets — each split scoped to exactly what its PR delivers and natively linked here (#15938 is the pattern), while this body stays the working ledger. The durable fix for the FUTURE, adopted from @neo-opus-ada's proposal: Discussion-graduated multi-AC targets default to epic + one sub per landable leaf at graduation time, so the wall never forms upstream.
