WHALE.md in a vendor-neutral directory is self-contradictory
~/.agents/ is introduced as a vendor-neutral location, but GLOBAL_WHALE_VENDOR_NEUTRAL_PATH adds ~/.agents/WHALE.md at priority 3, ahead of ~/.agents/AGENTS.md at priority 4. A user who creates ~/.agents/AGENTS.md to share config across multiple tools could have it silently shadowed if they also happen to have ~/.agents/WHALE.md, without any warning. Lookups of WHALE.md there also only benefit codewhale, which undermines the vendor-neutral intent. Consider restricting ~/.agents/ to AGENTS.md only, or document the WHALE.md precedence explicitly.

~/.agents/WHALE.md path has no test coverage
GLOBAL_WHALE_VENDOR_NEUTRAL_PATH (~/.agents/WHALE.md) is a new constant added at priority 3, but neither new test exercises it. Both new tests only write to ~/.agents/AGENTS.md. If the path-building loop for WHALE.md had a typo or the constant were mis-ordered, nothing would catch it. A test confirming ~/.agents/WHALE.md is found when that file exists (and wins over ~/.agents/AGENTS.md in the same directory) would close this gap.

Code Review
This pull request introduces support for vendor-neutral global configuration paths (.agents/WHALE.md and .agents/AGENTS.md) as fallback options. The resolution priority has been updated so that .codewhale/ takes priority over .agents/, which in turn takes priority over the legacy .deepseek/ paths. Additionally, unit tests have been added to verify the fallback behavior and priority resolution. There are no review comments, and I have no additional feedback to provide.

The core idea of reading as a vendor-neutral fallback is good. But the PR also introduces at priority 3, above at priority 4 — which contradicts the vendor-neutral intent and creates a silent shadowing hazard.
Requested changes:
- Remove from the candidate list entirely. If CodeWhale-specific global config is needed, it should go in (which is already higher priority at tier 1-2).
- Keep only in the vendor-neutral tier.
- Add a test verifying that is read but is NOT (to prevent regression).
The two new tests writing to are well-structured — those are fine to keep.

Greptile Summary
This PR inserts
~/.agents/as a new vendor-neutral fallback tier (priority 3–4) between the existing~/.codewhale/(priority 1–2) and~/.deepseek/(priority 5–6) global instruction directories, with two new tests covering theAGENTS.mdcase and priority ordering.GLOBAL_AGENTS_VENDOR_NEUTRAL_PATH(~/.agents/AGENTS.md) andGLOBAL_WHALE_VENDOR_NEUTRAL_PATH(~/.agents/WHALE.md) are added to the candidate list inload_global_agents_context; the first matching file wins and the rest are skipped.~/.agents/AGENTS.mdis loaded when no codewhale-specific file exists, and one confirming~/.codewhale/AGENTS.mdtakes priority over~/.agents/AGENTS.md.~/.agents/WHALE.mdpath (priority 3) has no corresponding test and sits above~/.agents/AGENTS.md(priority 4) in the same directory, which could silently shadow a user's vendor-neutral config.Confidence Score: 4/5
Safe to merge with minor cleanup; default behavior for existing users is unchanged.
The fallback logic is additive and only activates when neither ~/.codewhale/ nor ~/.agents/ files exist for current users, so there is no regression risk for anyone with an existing setup. The main gap is that ~/.agents/WHALE.md (priority 3) is added without a test and can silently shadow ~/.agents/AGENTS.md in the same directory — a user who relies on the vendor-neutral path could be surprised if they also have a WHALE.md there. The WHALE.md addition also sits oddly in a directory marketed as vendor-neutral.
crates/tui/src/project_context.rs — specifically the untested GLOBAL_WHALE_VENDOR_NEUTRAL_PATH constant and its interaction with GLOBAL_AGENTS_VENDOR_NEUTRAL_PATH.
