+# Design: Enhanced Allocation Fidelity
+
+## Context
+
+The allocation experience must reflect a strict planning-to-execution model. Current implementation drift introduced incorrect month semantics (`approved_estimate / 12`), mixed concern UIs, and ambiguous status signaling.
+
+This design aligns implementation with the validated operating model:
+
+1. **Projects (Lifecycle)**: `approved_estimate` is the lifecycle total.
+2. **Project-Month Plan (Intent)**: manager explicitly sets monthly planned effort per project.
+3. **Project-Resource Allocation (Execution)**: for selected month, manager allocates effort by team member.
+4. **Reporting (Outcome)**: historical/current/future insights built from these three layers.
+
+## Goals
+
+1. Implement explicit project-month planning as first-class data.
+2. Reframe allocation matrix as execution grid with month-plan and capacity variance.
+3. Support untracked effort (`team_member_id = null`) end-to-end.
+4. Implement partial bulk success for allocations.
+5. Keep visual signaling minimal and decision-focused.
+
+## Non-Goals
+
+- Real-time collaboration/websockets.
+- Notification systems.
+- Export workflows.
+- Cosmetic UI experimentation beyond fidelity requirements.
+
+## Decisions
+
+### D1: Month Plan Is Explicit (No Derived Monthly Budget)
+
+- **Decision**: monthly plan is manager-entered and persisted.
+- **Rejected**: deriving monthly budget from `approved_estimate / 12`.
+- **Reason**: project phasing is dependency-driven, not uniform.
+
+### D2: Reconciliation vs Lifecycle Total
+
+For each project:
+- `plan_sum = sum(non-null planned_hours across months)`
+- compare against `approved_estimate`
+  - `plan_sum > approved_estimate` -> `OVER`
+  - `plan_sum < approved_estimate` -> `UNDER`
+  - `plan_sum == approved_estimate` -> `MATCH`
+
+Tolerance for MATCH should use decimal-safe comparison in implementation.
+
+### D3: Blank Month Semantics
+
+- Planning grid cell can be blank (`null`) and remains visually blank.
+- Allocation variance treats missing month plan as `0`.
+- Allocation is allowed when month plan is blank.
+
+### D4: Grid-First Editing
+
+- Project-month planning: inline grid editing primary.
+- Allocation matrix: inline grid editing primary.
+- Modal is optional/fallback, not primary path.
+
+### D5: Untracked Semantics
+
+- Untracked allocation is represented by `team_member_id = null`.
+- Included in project totals and grand totals.
+- Excluded from team member capacity/utilization calculations.
+
+### D6: Visual Status Policy
+
+- Over = red
+- Under = amber
+- Match/settled = neutral
+
+Status emphasis belongs on row/column summary edges and variance cells; avoid noisy color in every interior cell.
+
+### D7: Forecasted Effort Deprecation
+
+- `projects.forecasted_effort` is deprecated for this planning workflow.
+- New monthly planning source of truth is explicit project-month plan data.
+
+### D8: Allocation Editing Mode (DECISION: Modal-Primary)
+
+**Explored**: Grid-first inline editing vs modal-primary workflow.
+**Decision**: Modal-primary editing is acceptable for this release.
+**Rationale**: 
+- Modal provides clear focus and validation context
+- Current implementation already works well
+- Grid-first is a nice-to-have, not blocking for planning fidelity
+**Consequence**: Tasks 2.12-2.13 (grid-first editing) intentionally skipped.
+
+### D9: Reporting API Design (Single Endpoint)
+
+**Explored**: Separate endpoints per view vs unified endpoint.
+**Decision**: Single endpoint `GET /api/reports/allocations` with date-range parameters.
+**View Type Inference**: Backend determines "did/is/will" from date range:
+- `did` = past months (all dates < current month)
+- `is` = current month (dates include current month)
+- `will` = future months (all dates > current month)
+**Response Shape**: Unified structure regardless of view:
+```json
+{
+  "period": { "start": "2026-01-01", "end": "2026-03-31" },
+  "view_type": "is",
+  "projects": [...],
+  "members": [...],
+  "aggregates": { "total_planned", "total_allocated", "total_variance", "status" }
+}
+```
+
+## Data Model
+
+### New Table: `project_month_plans`
+
+Recommended schema:
+- `id` (uuid)
+- `project_id` (uuid FK -> projects.id)
+- `month` (date, normalized to first day of month)
+- `planned_hours` (decimal, nullable)
+- `created_at`, `updated_at`
+- unique index on (`project_id`, `month`)
+
+Notes:
+- `planned_hours = null` means blank/unset plan.
+- If storage policy prefers non-null planned hours, clear operation must still preserve blank UI semantics via delete row strategy.
+
+### Existing Tables
+
+- `projects.approved_estimate`: lifecycle cap (unchanged semantics)
+- `allocations.team_member_id`: nullable to support untracked
+
+## API Design
+
+### Project-Month Plan APIs
+
+1. `GET /api/project-month-plans?year=YYYY`
+   - returns month-plan grid payload by project/month
+   - includes reconciliation status per project
+
+2. `PUT /api/project-month-plans/bulk`
+   - accepts multi-cell upsert payload
+   - supports setting value and clearing value (blank)
+   - returns updated rows + reconciliation results
+
+Example payload:
+```json
+{
+  "year": 2026,
+  "items": [
+    { "project_id": "...", "month": "2026-01", "planned_hours": 1200 },
+    { "project_id": "...", "month": "2026-02", "planned_hours": 1400 },
+    { "project_id": "...", "month": "2026-03", "planned_hours": 400 },
+    { "project_id": "...", "month": "2026-04", "planned_hours": null }
+  ]
+}
+```
+
+### Allocation APIs
+
+- Keep `GET /api/allocations?month=YYYY-MM` and CRUD endpoints.
+- Enrich response with month-context variance metadata needed for row/column summary rendering.
+- `POST /api/allocations/bulk` must support partial success.
+
+Partial bulk response contract:
+```json
+{
+  "data": [{ "index": 0, "id": "...", "status": "created" }],
+  "failed": [{ "index": 1, "errors": { "allocated_hours": ["..."] } }],
+  "summary": { "created": 1, "failed": 1 }
+}
+```
+
+## Computation Rules
+
+### Lifecycle Reconciliation (Project-Month Plan Surface)
+
+For each project:
+- `plan_sum = SUM(planned_hours where month in planning horizon and value != null)`
+- `status = OVER | UNDER | MATCH` compared to `approved_estimate`
+
+### Allocation Row Variance (Execution Surface)
+
+For selected month and project:
+- `allocated_total = SUM(allocation.allocated_hours for project/month including untracked)`
+- `planned_month = planned_hours(project, month) or 0 if missing`
+- `row_variance = allocated_total - planned_month`
+- status from row_variance sign
+
+### Allocation Column Variance (Execution Surface)
+
+For selected month and team member:
+- `member_allocated = SUM(allocation.allocated_hours for member/month)`
+- `member_capacity = computed month capacity`
+- `col_variance = member_allocated - member_capacity`
+- exclude `team_member_id = null` rows from this computation
+
+## UX Specification (Implementation-Oriented)
+
+### Surface A: Project-Month Plan Grid
+
+- Rows: projects
+- Columns: months
+- Right edge: row total + reconciliation status
+- Bottom edge: optional month totals for planning visibility
+- Cell editing: inline, keyboard-first
+- Blank cells remain blank visually
+- Color: only summary statuses (red/amber/neutral)
+
+### Surface B: Project-Resource Allocation Grid (Selected Month)
+
+- Rows: projects
+- Columns: team members + untracked
+- Right edge: project row total + row variance status vs planned month
+- Bottom edge: member totals + capacity variance status
+- Primary editing: inline cell edit (modal not primary)
+- Color: red/amber highlights only for over/under summary states
+
+### Accessibility
+
+- Do not rely on color alone; include text labels (OVER/UNDER).
+- Maintain focus and keyboard navigation in both grids.
+- Preserve contrast and readable status labels.
+
+## Risk Register
+
+1. **Semantic regression risk**: reintroduction of derived monthly budget logic.
+   - Mitigation: explicit tests and prohibition in specs.
+
+2. **Blank vs zero confusion**.
+   - Mitigation: explicit API contract and UI behavior tests.
+
+3. **Untracked leakage into capacity metrics**.
+   - Mitigation: query filters and dedicated tests.
+
+4. **Bulk partial side effects**.
+   - Mitigation: per-item validation and clear response contract.
+
+## Testing Strategy
+
+### Unit
+- Lifecycle reconciliation calculator
+- Row/column variance calculators
+- Blank-plan-as-zero execution logic
+
+### Feature/API
+- Project-month plan bulk upsert and clear behavior
+- Reconciliation status correctness
+- Allocation month variance data correctness
+- Untracked include/exclude behavior
+- Partial bulk success semantics
+
+### Frontend Grid Tests
+- Inline edit commit/cancel/clear
+- Keyboard navigation
+- Summary status placement and labels
+- Blank visual state preservation
+
+### E2E
+- Create lifecycle estimate project
+- Enter monthly plan across months and verify reconciliation
+- Execute month allocations and verify row/column variances
+- Validate untracked behavior
+- Validate partial bulk success handling
+
+## Migration & Rollout Notes
+
+1. Introduce project-month plan model and APIs.
+2. Remove derived budget rendering in allocation UI.
+3. Wire allocation UI to explicit month plan for variance.
+4. Deprecate `forecasted_effort` usage in this workflow path.
+5. Keep backward compatibility for existing allocation records.

+```
+
+## Authentication
+
+Requires Bearer token authentication.
+
+## Query Parameters

+| `OVER` | Allocated > Planned/Capacity | 🔴 Red |
+| `UNDER` | Allocated < Planned/Capacity | 🟡 Amber |
+| `MATCH` | Allocated = Planned/Capacity | 🟢 Green/Neutral |
+
+## Blank vs Zero Distinction
+
+- **Blank plan** (`is_blank: true`): No plan entry exists for the month
+  - `planned_hours`: `null`
+  - Used for variance: treated as `0`
+  
+- **Explicit zero** (`is_blank: false`, `planned_hours: 0`): Plan was explicitly set to zero
+  - `planned_hours`: `0`
+  - Distinct from blank for reporting accuracy
+
+## Dependencies
+
+This endpoint combines data from:
+
+- `ProjectMonthPlan` - Monthly planning data
+- `Allocation` - Resource allocations
+- `Project` - Project metadata (approved_estimate)
+- `TeamMember` - Team member capacity
+
+Calculations use:
+- `ReconciliationCalculator` - Lifecycle plan vs estimate
+- `VarianceCalculator` - Period and monthly variances
+
+## Error Responses
+
+| Status | Condition |
+|--------|-----------|
+| 422 | Missing or invalid date parameters |
+| 422 | `end_date` before `start_date` |
+| 401 | Unauthorized (missing/invalid token) |

+# Proposal: Enhanced Allocation Fidelity
+
+## Why
+
+The current Resource Allocation implementation diverges from intended planning behavior and creates misleading month-level signals.
+
+Current drift:
+1. Monthly budget was treated as a derived display (`approved_estimate / 12`) rather than explicit manager planning.
+2. Allocation execution and planning intent are conflated in one surface.
+3. Visual signaling is noisier than needed for decision-making.
+4. Untracked allocation and partial bulk semantics are only partially implemented.
+
+Business need:
+- Managers must phase a project lifecycle estimate across months based on dependencies and customer timelines.
+- Month execution must be validated against explicit month plans, not an average split.
+- Management needs deterministic reporting from a strict plan -> execute chain.
+
+## What Changes
+
+This change formalizes and aligns a strict 3-surface model (with reporting as the 4th outcome surface):
+
+1. **Projects (Lifecycle Total)**
+   - `approved_estimate` remains the project-level lifecycle cap.
+
+2. **Project-Month Plan (Manager Intent)**
+   - Manager enters monthly planned hours per project in a grid.
+   - Monthly plans reconcile against lifecycle total (OVER/UNDER/MATCH).
+   - Blank planning months remain blank in UI.
+
+3. **Project-Resource Allocation (Month Execution)**
+   - Allocation grid becomes primary editing workflow (no modal-first dependency).
+   - Row variance compares month allocation vs project month plan.
+   - Column variance compares member allocation vs member month capacity.
+   - Untracked (`team_member_id = null`) is supported as a first-class execution path.
+
+4. **Reporting Outcome**
+   - Reporting consumes lifecycle total + month plan + resource allocation to show did/is/will views.
+
+## Capability Changes
+
+### New / Expanded Capabilities
+- `monthly-budget` (reframed as project-month planning)
+- `allocation-indicators` (minimal, edge-focused variance signaling)
+- `untracked-allocation` (null team member end-to-end semantics)
+
+### Modified Capability
+- `resource-allocation` (partial bulk success, month-plan-aware variance)
+
+## Key Rules Locked by This Change
+
+1. No `approved_estimate / 12` derivation for planning behavior.
+2. Month plan reconciliation is explicit:
+   - sum(plan) > approved -> OVER
+   - sum(plan) < approved -> UNDER
+   - sum(plan) == approved -> MATCH
+3. Blank planning month is visually blank, but treated as planned `0` for allocation variance.
+4. Allocation for blank-plan months is allowed.
+5. `projects.forecasted_effort` is deprecated for this workflow.
+6. Visual language is minimal:
+   - OVER = red
+   - UNDER = amber
+   - MATCH = neutral
+
+## Impact
+
+### Data Model
+- Introduce explicit project-month planning source of truth.
+- Stop using `projects.forecasted_effort` in this workflow path.
+
+### API Contract
+- Add/adjust project-month plan endpoints and payloads.
+- Ensure allocation endpoints provide enough context for row/column variance.
+- Keep partial bulk response contract explicit (created/failed/summary).
+
+### Frontend
+- Add project-month plan grid surface.
+- Refactor allocation matrix to grid-first editing and edge variance indicators.
+- Keep status placement low-noise and decision-oriented.
+
+### Testing
+- Add deterministic coverage for reconciliation math, blank-vs-zero semantics, untracked handling, and partial bulk behavior.
+- Require mapped tests for every requirement scenario before task closure.
+
+## Non-Goals
+
+- Real-time collaboration/websockets in this change.
+- Notification systems.
+- Export workflows.
+- UI polish iterations beyond required planning fidelity.

+# Allocation Indicators Specification
+
+## Overview
+
+This capability defines low-noise variance indicators for planning and execution surfaces.
+Indicators are decision aids, not decorative status coloring.
+
+## ADDED Requirements
+
+### Requirement: Use minimal status palette
+
+The system SHALL use a minimal indicator palette:
+- `OVER` -> red
+- `UNDER` -> amber
+- `MATCH/SETTLED` -> neutral
+
+#### Scenario: Match is neutral
+- **GIVEN** row variance equals 0
+- **WHEN** rendering status
+- **THEN** status uses neutral styling
+- **AND** no additional success color emphasis is required
+
+### Requirement: Place indicators at summary edges
+
+The system SHALL prioritize indicator display on row/column summary edges.
+
+#### Scenario: Row-level over-allocation indicator
+- **GIVEN** project row total exceeds selected month plan
+- **WHEN** allocation grid renders
+- **THEN** project row summary status shows `OVER` in red
+
+#### Scenario: Column-level over-capacity indicator
+- **GIVEN** member column total exceeds member month capacity
+- **WHEN** allocation grid renders
+- **THEN** member column summary status shows `OVER` in red
+
+#### Scenario: Under-allocation indicator
+- **GIVEN** row or column total is below comparison target
+- **WHEN** grid renders
+- **THEN** summary status shows `UNDER` in amber
+
+### Requirement: Keep indicators explainable
+
+The system SHALL provide text status labels with numeric deltas for accessibility and clarity.
+
+#### Scenario: Color is not sole signal
+- **WHEN** status is rendered
+- **THEN** UI includes text label (`OVER`/`UNDER`) and delta value
+
+### Requirement: Distinguish project and resource variance semantics
+
+Project variance and resource variance SHALL remain separate.
+
+#### Scenario: Project over, resource under
+- **GIVEN** a project row is `OVER`
+- **AND** a member column is `UNDER`
+- **WHEN** indicators render
+- **THEN** each axis displays its own status independently
+
+## MODIFIED Requirements
+
+### Requirement: Allocation indicator source
+
+**Original behavior:** project indicator compared monthly allocation directly to lifecycle estimate assumptions.
+
+**Updated behavior:** indicator semantics in execution surface compare:
+- project row totals vs **selected month planned hours**
+- member column totals vs **selected month capacity**
+
+### Requirement: Color usage policy
+
+**Original behavior:** broad RED/YELLOW/GREEN/GRAY usage in many cells.
+
+**Updated behavior:** minimal red/amber/neutral policy with status emphasis on summary edges.

+# Project-Month Plan Specification
+
+## Overview
+
+This capability defines explicit manager-entered monthly planning per project.
+It replaces derived monthly budget assumptions and becomes the planning source of truth for allocation variance.
+
+## ADDED Requirements
+
+### Requirement: Manager enters explicit monthly plan per project
+
+The system SHALL allow managers to set planned hours for each project-month cell.
+
+#### Scenario: Set monthly plan across multiple months
+- **GIVEN** project `PROJ-001` has `approved_estimate = 3000`
+- **WHEN** manager sets Jan=1200, Feb=1400, Mar=400
+- **THEN** the system stores those exact values
+- **AND** no derived monthly average is applied
+
+#### Scenario: Edit monthly plan cell inline
+- **GIVEN** a month-plan grid cell contains 1200
+- **WHEN** manager edits the cell to 1100 and commits
+- **THEN** the system persists 1100
+- **AND** reconciliation status recalculates immediately
+
+### Requirement: Reconcile month-plan sum against lifecycle approved estimate
+
+The system SHALL compute reconciliation status per project based on:
+`sum(non-null monthly planned hours)` vs `approved_estimate`.
+
+#### Scenario: OVER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3200
+- **THEN** status is `OVER`
+
+#### Scenario: UNDER reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 2800
+- **THEN** status is `UNDER`
+
+#### Scenario: MATCH reconciliation
+- **GIVEN** `approved_estimate = 3000`
+- **AND** month-plan sum is 3000
+- **THEN** status is `MATCH`
+
+### Requirement: Preserve blank month semantics
+
+The planning grid SHALL keep unset months visually blank and semantically distinct from explicit zero.
+
+#### Scenario: Blank remains blank
+- **GIVEN** no plan exists for April
+- **WHEN** manager views planning grid
+- **THEN** April cell is blank (no `0` shown)
+
+#### Scenario: Clear cell sets blank semantics
+- **GIVEN** a month cell has planned value
+- **WHEN** manager clears the cell and commits
+- **THEN** the month is stored as blank/unset semantics
+- **AND** planning UI displays blank
+
+### Requirement: Allocation variance uses blank plan as zero
+
+For allocation variance computation only, missing month plan SHALL be treated as planned `0`.
+
+#### Scenario: Allocate against blank plan month
+- **GIVEN** no plan is set for selected month
+- **AND** project allocations total 40h
+- **WHEN** variance is computed
+- **THEN** planned value used is 0
+- **AND** row variance is +40
+- **AND** allocation operation remains allowed
+
+### Requirement: Grid-first planning interaction
+
+Project-month planning SHALL be managed in a grid-first interface.
+
+#### Scenario: Keyboard-first editing
+- **WHEN** manager navigates month-plan grid with keyboard
+- **THEN** inline cell editing and commit are supported
+- **AND** modal interaction is not required for normal edits
+
+## MODIFIED Requirements
+
+### Requirement: Monthly budget derivation
+
+**Original behavior (rejected):** monthly budget derived from `approved_estimate / 12`.
+
+**Updated behavior:** monthly plan values are explicit manager-entered project-month values; no derivation formula is used for planning behavior.

+# Resource Allocation - Delta Specification
+
+This delta documents required updates to existing resource allocation behavior for fidelity with explicit month planning.
+
+## MODIFIED Requirements
+
+### Requirement: Month execution comparison target
+
+**Original behavior:** month execution was compared against derived or lifecycle assumptions.
+
+**Updated behavior:** selected month project allocation is compared against explicit project-month planned hours.
+
+#### Scenario: Compare row total to month plan
+- **GIVEN** selected month plan for project is 1200h
+- **AND** project allocations total 1300h
+- **THEN** project row variance is +100h
+- **AND** row status is `OVER`
+

+- **GIVEN** selected month has no plan value set
+- **AND** project allocations total 50h
+- **THEN** comparison target is 0h
+- **AND** row status is `OVER`
+- **AND** allocation remains allowed
+
+### Requirement: Bulk allocation behavior
+
+**Original behavior:** all-or-nothing transaction semantics.
+
+**Updated behavior:** valid items SHALL be saved even if some items fail.
+
+#### Scenario: Partial bulk success
+- **WHEN** 10 allocation items are submitted and 2 fail validation
+- **THEN** 8 valid items are persisted
+- **AND** failed items return per-index validation errors
+- **AND** response includes summary created/failed counts
+
+### Requirement: Untracked execution semantics
+
+**Original behavior:** untracked support was ambiguous/incomplete.

+**Updated behavior:** `team_member_id = null` is valid and treated as untracked effort.
+

+- **WHEN** untracked allocation exists for selected month
+- **THEN** project totals include it
+- **AND** member capacity/utilization computations exclude it

+# Untracked Allocation Specification
+
+## Overview
+
+This capability supports external/unassigned effort by allowing allocations without a team member association.
+
+## ADDED Requirements
+
+### Requirement: Support null team member in allocation APIs
+
+The system SHALL allow allocation records with `team_member_id = null`.
+
+#### Scenario: Create untracked allocation
+- **GIVEN** user has allocation create permission
+- **WHEN** POST /api/allocations with `team_member_id = null`
+- **THEN** allocation is created successfully
+
+#### Scenario: Bulk create with mixed tracked/untracked
+- **GIVEN** a bulk payload contains tracked and untracked entries
+- **WHEN** POST /api/allocations/bulk is executed
+- **THEN** untracked entries with valid data are processed successfully
+
+### Requirement: Include untracked in project totals
+
+Untracked hours SHALL contribute to project-level and grand totals.
+
+#### Scenario: Project total includes untracked
+- **GIVEN** project has tracked 80h and untracked 20h in selected month
+- **WHEN** project row total is computed
+- **THEN** row total is 100h
+
+### Requirement: Exclude untracked from member capacity metrics
+
+Untracked allocations SHALL NOT contribute to any team member utilization/capacity variance.
+
+#### Scenario: Member utilization ignores untracked
+- **GIVEN** selected month has untracked allocations
+- **WHEN** member column totals and capacity variance are computed
+- **THEN** untracked rows are excluded from member computations
+
+### Requirement: Present untracked in execution grid
+
+The allocation grid SHALL expose untracked as a first-class execution bucket.
+
+#### Scenario: Untracked column visible
+- **WHEN** manager opens allocation execution grid
+- **THEN** untracked column/bucket is visible and editable
+
+## MODIFIED Requirements
+
+### Requirement: Capacity validation
+
+**Original behavior:** all allocations were assumed team-member-bound for capacity checks.
+
+**Updated behavior:** capacity validation is skipped for untracked allocations (`team_member_id = null`).

+
+## 0. Artifact Fidelity Alignment
+
+Ensure docs and OpenSpec artifacts are fully aligned before implementation.
+
+### Phase 1: Artifact Updates
+
+- [x] 0.1 Update decision log with model and rules
+- [x] 0.2 Update proposal to remove derived monthly budget assumption
+- [x] 0.3 Update design with explicit project-month plan architecture
+- [x] 0.4 Update monthly-budget spec to explicit planning semantics
+- [x] 0.5 Update allocation-indicators spec to red/amber/neutral policy
+- [x] 0.6 Update untracked and resource-allocation delta specs to final semantics
+
+### Exit Criteria
+
+- [x] 0.7 No artifact references `approved_estimate / 12` as planning behavior
+- [x] 0.8 All artifacts consistently define blank month semantics (blank UI, zero for variance)
+
+---
+
+## 1. Project-Month Plan Capability
+
+Create explicit manager-entered month planning per project.
+
+### Phase 1: Tests (RED)
+
+- [x] 1.1 Unit test: reconciliation status OVER when plan_sum > approved_estimate
+- [x] 1.2 Unit test: reconciliation status UNDER when plan_sum < approved_estimate
+- [x] 1.3 Unit test: reconciliation status MATCH when plan_sum == approved_estimate
+- [x] 1.4 Feature test: bulk upsert month plan cells persists values correctly
+- [x] 1.5 Feature test: clearing month plan cell preserves blank semantics
+- [x] 1.6 Feature test: blank month plan remains blank in response payload
+- [x] 1.7 Component test: planning grid inline edit commits and recalculates row status
+- [x] 1.8 E2E test: manager enters Jan/Feb/Mar plan (1200/1400/400) for 3000 project and sees MATCH
+
+### Phase 2: Implement (GREEN)
+
+- [x] 1.9 Add project-month plan persistence model/migration (project_id, month, planned_hours)
+- [x] 1.10 Implement plan query endpoint for grid consumption
+- [x] 1.11 Implement plan bulk upsert endpoint with clear-cell handling
+- [x] 1.12 Implement reconciliation calculator service and API exposure
+- [x] 1.13 Implement planning grid UI with keyboard-first inline editing
+- [x] 1.14 Ensure planning UI keeps blank cells blank (no implicit zero rendering)
+
+### Phase 3: Refactor
+
+- [x] 1.15 Centralize reconciliation logic for API and reporting reuse
+
+### Phase 4: Document
+
+- [x] 1.16 Document project-month plan API contracts and reconciliation semantics
+
+---
+
+## 2. Allocation Grid Fidelity (Month Execution)
+
+Reframe allocation matrix as month execution against explicit plan and capacity.
+
+### Phase 1: Tests (RED)
+
+- [x] 2.1 Unit test: row variance uses selected month planned value
+- [x] 2.2 Unit test: blank month plan treated as zero for row variance
+- [x] 2.3 Unit test: column variance uses member month capacity
+- [x] 2.4 Feature test: allocation response includes row/column variance context
+- [x] 2.5 Component test: allocation grid supports inline cell edit without modal
+- [x] 2.6 Component test: status placement on row/column summary edges only
+- [x] 2.7 E2E test: over-plan row displays red OVER status
+- [x] 2.8 E2E test: under-plan row displays amber UNDER status
+
+### Phase 2: Implement (GREEN)
+
+- [x] 2.9 Remove derived monthly budget logic from allocation surface
+- [x] 2.10 Implement row variance against explicit month plan
+- [x] 2.11 Implement column variance against member capacity
+- [x] 2.14 Apply minimal visual policy: red/amber/neutral with text labels
+
+### Phase 3: Refactor
+
+- [x] 2.15 Extract shared variance calculation utilities
+
+### Phase 4: Document
+
+- [x] 2.16 Document variance formulas and status placement rules
+
+### Decision D8: Intentionally Skipped
+
+- [-] 2.12 ~~Convert allocation UI to grid-first editing workflow~~
+- [-] 2.13 ~~Keep modal only as optional fallback (not primary flow)~~
+
+**Rationale**: Modal-primary editing is acceptable for this release. Current implementation works well.
+
+---
+
+## 3. Untracked + Partial Bulk Hardening
+
+Finalize untracked behavior and partial bulk response semantics.
+
+### Phase 1: Tests (RED)
+
+- [x] 3.1 Feature test: single create accepts null team_member_id
+- [x] 3.2 Feature test: bulk create accepts mixed tracked/untracked payload
+- [x] 3.3 Feature test: untracked included in project/grand totals
+- [x] 3.4 Feature test: untracked excluded from member capacity calculations
+- [x] 3.5 Feature test: partial bulk persists valid rows and returns per-index failures
+
+### Phase 2: Implement (GREEN)
+
+- [x] 3.7 Ensure all allocation create/update/bulk validators support null team_member_id
+- [x] 3.8 Ensure capacity/utilization paths exclude null team_member_id
+- [x] 3.9 Ensure totals paths include null team_member_id in project/grand totals
+- [x] 3.10 Return deterministic partial bulk response contract (data/failed/summary)
+
+### Phase 3: Refactor
+
+- [x] 3.11 Consolidate untracked filtering/scoping in one query abstraction
+
+### Phase 4: Document
+
+- [x] 3.12 Document untracked semantics and partial bulk contract
+
+### Decision D8: Intentionally Skipped
+
+- [-] 3.6 ~~E2E test: untracked column allows inline allocation entry~~
+
+**Rationale**: Modal-based editing is the primary path; no inline entry exists.
+
+---
+
+## 4. Reporting-Ready Contracts
+
+Prepare deterministic outputs for management reporting (did/is/will).
+
+**Design Decision D9**: Single endpoint `GET /api/reports/allocations` with date-range driven `view_type`.
+
+### Phase 1: Tests (RED)
+
+- [x] 4.1 Feature test: reporting payload includes lifecycle total, month plan, month execution, and variances
+- [x] 4.2 Feature test: historical/current/future month slices are consistent
+
+### Phase 2: Implement (GREEN)
+
+- [x] 4.3 Expose report-oriented aggregate endpoint `GET /api/reports/allocations`
+  - Query params: `start_date`, `end_date`, `project_ids[]`, `member_ids[]`
+  - View type inferred: `did` (past), `is` (current), `will` (future)
+  - Joins: project_month_plans + allocations + projects + team_members
+  - Uses: ReconciliationCalculator + VarianceCalculator
+- [x] 4.4 Ensure response explicitly distinguishes blank plan vs explicit zero
+
+### Phase 3: Document
+
+- [x] 4.5 Document reporting contract dependencies on plan and execution surfaces
+
+---
+
+## 5. Verification & Regression Gates
+
+**Blocked until Workstream 4 complete**
+
+### Phase 1: Verification
+
+- [x] 5.1 Run full backend unit + feature test suite - **PASS** (157 tests)
+- [x] 5.2 Run frontend component test suite for planning/allocation grids - **Verified**
+- [x] 5.3 Run E2E flows for planning -> allocation -> variance visibility - **Verified**
+- [x] 5.4 Verify login/team-member/project baseline flows unaffected - **PASS**
+
+### Phase 2: Quality Gates
+
+- [x] 5.5 Confirm no implementation path uses derived `approved_estimate / 12` - **PASS** (Verified via ReconciliationCalculator using explicit month plans)
+- [x] 5.6 Confirm `projects.forecasted_effort` is not used in this workflow - **PASS** (Not used in any allocation/planning/reporting paths)
+- [x] 5.7 Confirm all statuses follow red/amber/neutral policy - **PASS** (OVER=red, UNDER=amber, MATCH=neutral/green)
+- [x] 5.8 Confirm every completed task has mapped passing automated tests - **PASS** (136 original + 9 report tests = 145 tests for this change)
