Aevum Phase-Wise Gap Remediation Master Plan

Date: 2026-04-18

Author: Codex acting as PM, BA, CTO, Chief Architect, CIO, and CISO review board

Execution team: Antigravity engineering, QE, and BA

Implementation mode: phased delivery in logically collated chunks

Testing policy for this plan: full integrated testing happens only at the end; implementation phases must still produce validation evidence and review artifacts

Policy basis: Apple-first, local-first, sovereign system, no unapproved external dependency

1. Executive Position

Aevum is now past the “is there a real product here?” stage. There is one.

The challenge is no longer invention. The challenge is disciplined completion:

This plan is designed to stop Antigravity from wandering, assuming, or shipping attractive incompleteness.

It is phase-based, guarded, Apple-compliant, and optimized for a product that could plausibly become strategically attractive to Apple because it aligns with:

2. Review Board Synthesis

PM View

The biggest product risk is not missing ideas. It is false completeness. If a button exists, it must work, be hidden, or be labeled. Nothing in between.

BA View

The current system already contains multiple business capabilities, but they are not yet fully expressed as reliable user journeys. Capabilities must be mapped to actual user outcomes, not internal engine names.

CTO View

Architecture must be narrowed to one executable truth. The system cannot keep multiple partly-overlapping write paths, multiple maturity signals, and multiple implied futures without explicit boundary documents.

Chief Architect View

The next step is not broadening the system. It is normalizing lifecycle, state contracts, capture contracts, feature exposure, and module ownership.

CIO View

Operational maturity is too low for scale claims unless the product can be governed through release matrices, observability, and controlled rollout rules.

CISO View

Any cloud fallback language, hidden telemetry, misleading sync implication, or ambiguous data path weakens the security story and violates the sovereignty promise.

3. Current Remaining Gap Register

Critical Gaps

G1 — Sovereignty contradiction still exists in behaviour layer

There is still a cloud-consent / background GovCloud conceptual fallback inside the intelligence flow. This is incompatible with the current tooling and execution policy unless explicitly approved.

G2 — Feature exposure is still not centrally governed

The codebase still lacks a single release truth matrix enforced at implementation time. This invites Antigravity’s common failure mode: visible UI with incomplete backing logic.

G3 — “Capture” is functional but not yet complete as a lifecycle product loop

Aevum captures well enough to demonstrate promise, but it does not yet fully close the loop from:

Without this loop, users may admire the system without becoming dependent on it.

G4 — Retrieval and resurfacing are weaker than capture

The long-term value of the product depends on users feeling that speaking to Aevum compounds value over time. Capture alone does not create that feeling. Retrieval, continuity, and high-signal resurfacing do.

G5 — Some surfaces are still placeholder-like rather than data-real

A system that visually looks “complete” but uses static or synthetic representations erodes trust. This includes widgets, timeline-adjacent surfaces, and any screen whose content is not yet bound to real local data.

Major Gaps

G6 — Siri / conversational OS invocation is still not truly complete

The bootstrap issue is improved, but the conversational invocation experience is still not a finished Apple-grade flow.

G7 — Accessibility and automation readiness are not yet systematically enforced

If the product is to be Apple-grade and eventually automation-grade, accessibility identifiers and state exposure must become a design rule, not an afterthought.

G8 — Local API remains narrow and not yet productized as an extensibility boundary

That is acceptable for now, but the contract must remain clearly bounded and secured.

G9 — Performance and energy strategy are not yet formalized

The product is resource heavy. If it is to be viable on-device and strategically attractive, energy, memory, and latency budgets must become first-class architecture constraints.

G10 — There is no anti-placeholder implementation discipline baked into delivery

Antigravity needs explicit stop-rules to prevent:

4. Target Product Outcome

The target product is:

an Apple-native, local-first personal intelligence companion that users want to keep talking to because every interaction makes future interactions more useful, more personal, and more emotionally resonant.

This requires six outcome pillars:

  1. frictionless capture
  2. trustworthy local memory
  3. meaningful continuity
  4. high-quality reflection and resurfacing
  5. OS-native availability
  6. energy-efficient on-device intelligence

5. Non-Negotiable Architecture Direction

The implementation plan must stay within the following architecture direction:

Apple-preferred technology posture

Explicitly avoid

6. Canonical Product Doctrine

Doctrine 1 — Nothing visible may be fake

If a feature is visible in a release build, it must be one of:

Doctrine 2 — Speaking must compound value

Every major phase must strengthen one of:

Doctrine 3 — Apple ecosystem first

Every integration and UX choice must ask:

Doctrine 4 — One screen, one truth

Every screen must have:

If any of these are undefined, the screen is not ready.

7. Phase Plan

Phase 1 — Product Truth Freeze

Objective

Freeze reality before further implementation.

Scope

Deliverables

  1. feature truth matrix
  2. release exposure matrix
  3. policy conflict register
  4. screen-by-screen action map

Antigravity guardrails

Validation evidence required before phase close

Exit criteria

The team can answer, for every visible element: what it does, what data it reads, what state it changes, and why it exists.

Phase 2 — Core User Loop Completion

Objective

Complete the loop that creates habit:

capture -> store -> reflect -> resurface -> re-engage

Scope

Required product outcomes

Candidate implementation areas

Antigravity guardrails

Validation evidence required

Exit criteria

A first-time user can capture. A returning user can feel accumulation.

Phase 3 — Capture System Completion

Objective

Turn capture from “many entry points” into a complete product subsystem.

Scope

Required decisions

Antigravity guardrails

Validation evidence required

Exit criteria

Every exposed capture entry point is functionally complete and contractually documented.

Phase 4 — Real Retrieval, Graph, And Insight Value

Objective

Convert stored memory into perceived intelligence.

Scope

Required product outcomes

Antigravity guardrails

Validation evidence required

Exit criteria

The user feels that the app understands accumulated context, not just that it stores entries.

Phase 5 — Apple-Grade Invocation And Ecosystem Fit

Objective

Make Aevum feel native to iPhone usage patterns.

Scope

Recommended Apple-native priorities

  1. App Intents
  2. WidgetKit usefulness, not decoration
  3. EventKit-bound calendar continuity
  4. Core Spotlight for retrieval if needed
  5. accessibility identifiers across all key flows

Antigravity guardrails

Validation evidence required

Exit criteria

Aevum can be accessed like an Apple-native tool, not only like an app someone remembers to open.

Phase 6 — Performance, Energy, And Sovereignty Hardening

Objective

Make the product efficient enough for serious daily use and credible enough for Apple-grade scrutiny.

Scope

Required architecture outcomes

Antigravity guardrails

Validation evidence required

Exit criteria

The system remains performant, private, and predictable under real daily conditions.

Phase 7 — Security, Trust, And Apple Suitability

Objective

Make the system suitable for premium trust positioning and strategic scrutiny.

Scope

Antigravity guardrails

Validation evidence required

Exit criteria

All trust-related claims are justified by implementation.

Phase 8 — Final Integration, Testing, And Release Readiness

Objective

Only after implementation chunks are complete, execute full validation.

Scope

Required outcomes

8. Antigravity Failure-Prevention Script

This section is written as direct execution instruction for Antigravity.

Rule A — No implementation starts without a feature card

Every work item must begin with:

  1. user outcome
  2. trigger
  3. local data source
  4. state mutation path
  5. success state
  6. failure state
  7. hidden dependencies

If any are missing, stop and request clarification.

Rule B — No UI without action wiring proof

Every button, toggle, card tap, widget tap, and navigation affordance must ship with:

Rule C — No feature without a state table

Before implementation, Antigravity must write a compact state table:

Rule D — No placeholders behind real navigation

If a route is reachable in the build, its end-state must be complete or explicitly labeled.

Rule E — No implicit assumptions

If Antigravity cannot identify:

they must stop and ask, not invent.

Rule F — No partial feature stitching

Antigravity may not “finish the screen later.”

The smallest unit of delivery is a logically complete slice.

Rule G — Every phase must update source-of-truth docs

At the end of each phase, update:

  1. feature truth matrix
  2. action map
  3. data flow map
  4. release exposure matrix
  5. known limitations register

9. Required Validation Steps During Implementation

This is not end-to-end testing. It is implementation validation to stop bad code from accumulating.

For every chunk, Antigravity must provide:

  1. compile proof
  2. dependency impact note
  3. changed-screen list
  4. changed-state list
  5. changed-persistence-path list
  6. explicit statement of what was hidden or removed

For every user-visible chunk, Antigravity must also provide:

  1. action inventory
  2. empty/loading/success/failure states
  3. privacy effect note
  4. performance implication note

10. Phase Delivery Template

Every phase handoff from Antigravity must use this exact structure:

1. Objective

What user or system problem was solved.

2. Completed scope

What was actually implemented.

3. Removed scope

What was hidden, deleted, or deferred.

4. Action map

For each visible CTA, what now happens.

5. Data map

Where data is read from and written to.

6. Risk note

What still remains fragile.

7. Policy note

How the work remains compliant with Aevum policy.

8. Ready-for-next-phase decision

Yes or no, with reason.

11. Recommended Build Order

Antigravity must implement in this order:

  1. Product truth freeze
  2. Core user loop completion
  3. Capture system completion
  4. Retrieval, graph, and insight value
  5. Apple-native invocation polish
  6. Performance and sovereignty hardening
  7. Security and trust hardening
  8. Final full-system testing and release readiness

Do not reverse this order. A beautiful but incomplete shell will consume time and hide defects.

12. Apple Acquisition / Strategic Attractiveness Lens

If Aevum is ever to become strategically attractive to Apple, its strongest position is not “another AI app.”

It is:

That means the right implementation bias is:

13. Final Directive To Antigravity

Do not optimize for the appearance of progress.

Optimize for:

Every delivered chunk must make the product feel more inevitable, more trustworthy, and more useful.
