Email Task Unit

Atomic flat-row micro-queue with 0-call slot and 5-role pod.

Processes one parameterized email draft, triage, or follow-up per flat row with inline recipient context, suppression checks, and send-approval gating.

/components/email_task_unit.json /components/email_task_unit.md Open in Queue Commons

Inputs (Flat Row)

Single flat recipient/thread row
Tone & objective parameters

Atomic Queue & Lanes

aq38_email_task_unit
entities-db.teleon.dev
1 Recipient Flat Row
Thread & Fact Context
Approval Gate

Execution Modes & Agent Freedom

Deterministic (0 calls): three_mode_delivery_and_lens_projector_v1 (Suppression list, DKIM/SPF lint & template variable validator)
Hybrid (<=1 call): surface_onboarding_lens_calibrator_v1
AI Agent (1..6): cross_surface_gap_and_ux_auditor_v1 (Context-grounded 1-to-1 email composer & thread triager; Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions)

Outputs (Table Merge)

Validated email_draft/v1
Approval-gated delivery record

Modular 6-layer envelope & 0..32 Kleisli onion middlelayers (DB substrates exempt)

Inbound and outbound calls traverse versioned envelope layers and composable Kleisli middlelayers before reaching the swappable engine slot, while backing database kernels enforce 0 inline agent wrapper steps.

2. flexible_pointer_or_slice_carrier

8. slot.aq38_email_task_unit (Native | Pinned OSS | Wasm)
ACID DB Core: 0 agent wrapper steps

5-role component managing pod & engine-slot twins

0-Call Slot (R1_DET_ENGINE): Executes SQL, BM25F/Roaring, AST, or fuel-metered Wasm adapters behind a fixed typed engine_slot/v1, pairing pinned upstream OSS adapters with clean Teleon-native twins.
Solver+OpenSearch (R2_PRIMARY_SOLVER): Runs under Instructions + Resources + Freedom to search for new resources and new ways not bound by instructions on 1 self-contained depth-1 flat task row per lease.
Split-Supervisor (R3_QUEUE_SUPERVISOR): Watches queue depth, stalls, and context horizons; explodes oversized tasks into wave-ordered flat subtask rows while preserving the original parent intact for rollup verification and long-horizon benchmarking.
Repair+Shim (R4_DIAGNOSTIC_REPAIR): Reviews whether the edge contract itself failed before mutating code (LE-CONTRACT-002), repairs lease timeouts and schema mismatches, and synthesizes 0..32-step middlelayer shims.
CPOP+Distill (R5_VERIFIER_DISTILLER): Grades outputs across an independent model family (reviewer != producer) and distills recurring high-cost agent wins into 0-call deterministic Sister code.

Parent-preserving supervision, catch-all & optional SCD2 packs

Supervisor split (aq41): Oversized or stalled tasks split into wave-ordered subtask rows while keeping subdivided_parent intact for rollup verification and direct long-horizon benchmarks.
Optional SCD Type 2 packs (Store S12): Versioned pack_sk rows (valid_from_utc, valid_to_utc, is_current, edited_by) supply optional locales, settings, instructions, suggestion paths, and tools across bare_baseline, pre_materialized_flat, and on_demand_claim_hydrated modes.
Flexible carriers: inline_object, swhid_cas_pointer, http_206_byte_slice, d1_row_cursor, signed_r2_uri

Normalized tables, invariants & 1 flat task row

Cell host: entities-db.teleon.dev
Backlog table: teleon_core.adaptive_delivery_todo_backlog
Hydration: Normalized supporting tables join server-side into 1 flat row on claim
teleon_core.surface_lens_projections
teleon_core.adaptive_delivery_manifests
teleon_core.bot_and_contributor_lineage_index

Each downstream website keeps an isolated identity database and cookie while sharing non-personal content-addressed supply.
Delivery selects inline_answer (<=64 KiB), uri_manifest (<=8 MiB), or range_stream_206 (>8 MiB) deterministically.

Atomic micro-queue & Track 2 Sister objective

Atomic queue: aq38_email_task_unit via q18-delivery-surface-queue.teleon.dev
Track 2 Sister (SISTER-15): sq15-improve-delivery-queue.teleon.dev
Sister objective: Tune inline/URI/stream byte cutoffs, semantic cache hit rates, and isolated surface lens presets.

domain:email_opshorizon:1_recipient_per_rowgate:draft_for_approval

Bot & harness fleet actions (Codex, Claude Code, ChatGPT, Dots, Meta Muse, GrokBot)

Draft concise, plain-language emails grounded in verified recipient attributes
Verify zero broken placeholders, zero AI-slop filler, and strict suppression compliance
Stage outbound messages in draft_for_approval unless an explicit send grant is attached

Sister self-tuning areas & HTTP queue submission

Tune inline payload vs URI manifest vs HTTP 206 stream thresholds per client harness (DIM-07)
Add declarative surface lens presets for humanitarian SDG, ML competitions, and STEM domains (DIM-02, DIM-04)
Optimize contributor and bot lineage index queries for real-time reuse visibility (DIM-01, DIM-06)
