ARCH-R2-001 — task product requirements

• Task ID: ARCH-R2-001
• Artifact kind: product
• Artifact state: draft
• Roadmap status: Backlog
• Milestone: R2
• Execution allowed: false
• Evidence boundary: Creation of this draft does not approve implementation, deployment, testing, restore, release, or production use.

Parent product source

• docs/product/releases/PRD-R2-TELEGRAM-PHOTO-CAPTURE.md
• docs/product/PRODUCT-REQUIREMENTS.md

Task outcome

Define callback authorization, bounded staging/decoding, ciphertext/derivative flow, media references, deduplication, and restore.

This artifact narrows the parent release contract to ARCH-R2-001. It does not expand the release, change source precedence, or make a shared parent document task approval.

Scope and traceability

• Task type: Architecture
• Owner role: Technical Architect
• Requirement IDs: LID-TG-001, LID-TG-002, LID-TG-003, LID-TG-004, LID-TG-005, LID-TG-006, LID-TG-007, LID-TG-008, LID-TG-009, LID-TG-010, LID-OPS-005, LID-OPS-009, LID-OPS-011, LID-OPS-015, LID-OPS-018
• Dependencies: PRD-R2-001, REL-R1-001
• Deferred requirements excluded: LID-UP-004, LID-DEF-001, LID-DEF-002, LID-DEF-003, LID-DEF-004, LID-DEF-005, LID-DEF-006

Product acceptance scenarios

1. ARCH-R2-001-P-001 — Outcome: the task produces exactly the outcome above and the result is reviewable without implying a later task or release is complete.
2. ARCH-R2-001-P-002 — Boundary: every mapped requirement is addressed, every deferred requirement stays absent, and no authentic/private/human-only act is inferred from synthetic or public evidence.
3. ARCH-R2-001-P-003 — Evidence: the task's named acceptance evidence is retrievable, task-bound, independently reviewable, and no broader than the supported claim.

Required acceptance evidence

Approved task-specific technical plan for ARCH-R2-001 — Media Pipeline & Asset Lifecycle links owned modules, ADRs, threats/data flows, interfaces/data shapes, capacity, migration, restore, rollback, and Architect sign-off.

Product metric

Primary task metric: all mapped requirement outcomes and the three task scenarios have retrievable pass/fail evidence, with zero unresolved scope or product decision.

Non-goals

• Do not implement work owned by a dependent or later task.
• Do not admit authentic content without its named owner gate.
• Do not treat a prototype, document, code path, CI result, deployment, or backup upload as release acceptance.
• Do not add the seven deferred requirements.

Owner actions

• R2-OA-001 — see the Owner Action Ledger
• R2-OA-002 — see the Owner Action Ledger

These are relevant future gates, not a request for secrets or owner action during local task-artifact authoring. Their due/satisfied state is recorded separately in the readiness register.

Open product decisions

• Five-seat task-level Product approval is pending.
• Acceptance scenarios must be confirmed against the exact stable candidate before this artifact can become approved.

Product Manager disposition

Draft / Hold. The parent PRD/PID is a planning input. Substantive execution is not permitted until this exact task artifact and the complete dossier pass council review.
