Juan José Mata 157daf5176 Consolidate repository instructions after auditing their history (#3409)
* Document instruction inventory and preservation decisions

Trace main history from September 2025 through September 2026, including earlier policy origins. Record preserved requirements, detailed-guide destinations, stale facts, harness boundaries and explicit policy-strength decisions before consolidating instruction sources.

* Consolidate repository instructions into shared guidance

Keep AGENTS concise and vendor neutral, move detailed conventions into shared guides, and use thin adapters with preserved Cursor scopes. Preserve the strict pre-PR checks globally and document the stronger scope, retired migration pin and rule-generation trigger. Update existing API guidance verification without changing application behavior.

* Narrow the always-on Cursor UI adapter and correct the SimpleFIN comment

Split the design-system guidance out of docs/llm-guides/ui.md into
docs/llm-guides/design-system.md. The ui-ux-design-guidelines rule is
alwaysApply: true, so importing all of ui.md loaded the Stimulus,
localization and ViewComponent guidance (previously confined to scoped
rules) on every Cursor session; the always-on adapter now imports only the
design-system guide, matching the scope it had before the consolidation.
view_conventions and stimulus_conventions keep the full UI guide.

Also correct the stale Provider::Simplefin header comment: pending
inclusion defaults on and is resolved by the importer (explicit argument,
then SIMPLEFIN_INCLUDE_PENDING, then Setting.syncs_include_pending); the
previous comment described the flag as default-off.

* Read guidance files as UTF-8 in the API consistency validators

The frontmatter regex match ran against content read with the locale
default external encoding; the Cursor rule's description contains an em
dash, so under US-ASCII (LC_ALL=C) Regexp#match raised ArgumentError,
breaking the standalone no-Rails fallback the docs point contributors to.
Read all checked files with an explicit UTF-8 encoding in both the
standalone script and the Rails test.

# Development guides
Start with [repository guidance](../../AGENTS.md), then read the guide for the work
being changed. These guides hold the detailed conventions and procedures.
| Task | Guide |
| --- | --- |
| Understand the domain and write Rails code | [Architecture and conventions](architecture.md) |
| Set up an environment, run checks or prepare a PR | [Development and verification](development.md) |
| Write behavioral tests and fixtures | [Testing](testing.md) |
| Change design tokens or `DS::*` primitives | [Design system](design-system.md) |
| Change views, components, CSS, Stimulus or localization | [UI](ui.md) |
| Add or modify an API v1 endpoint | [API endpoint consistency](api-endpoint-consistency.md) |
| Change provider imports, pending/FX metadata or diagnostics | [Provider sync guidance](providers.md) |
| Add a securities price provider | [Provider walkthrough](adding-a-securities-provider.md) |
| Gate or release a preview feature | [Preview-feature gating](gating-a-preview-feature.md) |
| Change goals, pledges or reconciliation | [Goals](goals.md) |
## External wealth integration
[Wealth history with an external agent harness](wealth-agent-harness.md) describes
Sure's read-only tool interface and the boundary with an external wealth system.
The [wealth blueprint](wealth-blueprint.md) is reference architecture for that
separate system. Its working-memory files, private document vault and operating
protocol apply to that external project, not to every change in this repository.
## Instruction maintenance
[Harness adapters](harness-adapters.md) documents discovery, supported imports,
scoped loading and legacy helpers. The [preservation map](instruction-preservation-map.md)
records the inventory, history, dispositions and intentional policy decisions for
the consolidation; it is an audit record rather than additional coding policy.
