BusinessChat framework fan-out rules

This directory is an isolated clean-room starting point for the Linux BusinessChat port. Work only inside full/businesschat/. Do not edit application sources, another framework, package-wide manifests, shared integration/build files, or anything under reference/ or tests/acceptance/.

Immutable evidence

reference/immutable-files.sha256 seals this file, FANOUT_TASK.md, every reference input, and tests/acceptance/test_host.sh. Never rewrite, regenerate, or reseal those files. SDK headers, module maps, Swift interfaces, and TBD files are proprietary inputs: their paths and hashes are recorded, but their bytes must not be copied into this repository.

All extractor-emitted graph files are preserved byte-for-byte. Apple graphs can legitimately repeat a precise identifier. reference/public-surface.tsv contains one canonical row per exact ID under the fixed canonicalSurfacePolicy recorded in reference/symbol-graphs.json; duplicate occurrence and full-payload conflict counts remain explicit there. Never treat canonical compaction as evidence that the other raw occurrences did not exist.

reference/api-digester.json is a location-free compiler dump from the same pinned Xcode SDK. Reconcile it with the symbol graph before writing declarations: use it for imported ObjC USRs, superclass/protocol identity, selectors, type optionality, declaration attributes, and ordered enum children. The graph remains the canonical exact-ID census. reference/external-evidence.json pins independent binding sources available in the prepared cloud environment. They are a read-only secondary cross-check, never authority over the Apple-derived files and never runtime evidence. If sources conflict, defer the declaration and add an oracle question. Do not guess.

Required output

• Implement a real Linux module named BusinessChat and a loadable libBusinessChat.dylib. Put implementation Swift files in this framework directory, outside tests/, and list each one as a repo-relative path in businesschat_guest_sources.txt.
• Create coverage.tsv with the exact header precise status evidence notes. Include every precise identifier from reference/public-surface.tsv exactly once. Allowed statuses are implemented, declared, deferred, unavailable, and not-applicable. At least 17 rows must be implemented or declared for the leaf-full lane. A declaration that does not compile is not declared; behavior that was not exercised is not implemented. Every implemented row must cite test:full/businesschat/tests/agent/*Tests.swift#testName; define that exact test* function for the sealed runner to call. Every declared row must cite source:full/businesschat/<product-source>.swift#Symbol; the source must be listed in businesschat_guest_sources.txt and contain the exact identifier anchor. Deferred, unavailable, and not-applicable rows require explanatory notes.
• Create oracle-questions.tsv with the exact header precise question risk reason. Use an exact graph precise ID, or module for a cross-cutting question. Include at least one concrete question; do not guess behavior missing from public inputs.
• Create a nonempty README.md describing what is real, fail-closed, and still deferred. The primary implementation file must be BusinessChat.swift.
• Put focused behavioral checks in tests/agent/*Tests.swift as top-level, synchronous, no-argument functions named test*. Create tests/agent/BusinessChatLoadSmoke.swift with exactly these three logical lines (including the blank line): import BusinessChat, a blank line, and let frameworkLoadSmokeMarker = "BUSINESSCHAT_AGENT_RUNTIME_OK". The sealed gate generates the executable runner from implemented coverage rows, imports and explicitly loads the dylib, invokes every cited test exactly once, and emits the marker as its sole stdout. Loading and printing are acceptance plumbing, not behavioral evidence by themselves.
• When dependencies are listed below, create tests/agent/BusinessChatDependencyIdentity.swift. Import BusinessChat and every declared dependency and pass genuine dependency values through public BusinessChat APIs. This probe is for the clean EC2 integration build; the isolated host gate is not permission to create same-named stand-ins. Never declare a public framework-local substitute for a dependency-owned type.
• Preserve unavailable, entitlement-gated, hardware-only, and Apple-service behavior honestly. Prefer deterministic fail-closed errors or inert behavior over fabricated success. Do not add or prioritize #Preview support.

Before implementation, make a declaration-facts pass: exact graph ID and signature, matching API-digester node/USR, dependency owner, and any corroborating binding source location. Static sources do not establish defaults, callback timing, queues, retention, coding round trips, hardware behavior, or service success. Such behavior is implemented only with focused behavioral test evidence; the load-smoke marker alone proves none of it.

Build discipline

Run bash tests/acceptance/test_host.sh from this framework directory before committing. It validates evidence, coverage, the source manifest, warnings-as- errors compilation, dylib creation, import, linking, focused tests, and the exact load-smoke marker. Keep all generated products in temporary directories; remove .build, build, and scratch before reporting completion. Do not weaken or bypass the gate.
