The sort shim from the previous commit enforces canonical core ordering at runtime, so ZWSP prefixes are no longer needed. Removing them eliminates the Bun.stringWidth vs terminal-width drift that broke the TUI status bar (#3259).
Drop AGENT_LIST_SORT_PREFIXES and getAgentRuntimeName from agent-display-names; switch all call sites to getAgentDisplayName. getAgentListDisplayName stays as a thin alias for external importers.
Keep stripInvisibleAgentCharacters and the ZWSP regex paths so legacy session state and configs from v3.14.0-v3.16.0 still resolve.

Commit 708891dab fixed most test expectations after the gpt-5.5 model
promotion but missed 13 tests across 6 files that still expected
openai/gpt-5.4 in DEFAULT_CATEGORIES and AGENT_MODEL_REQUIREMENTS.
Updates all remaining stale expectations to openai/gpt-5.5:
- agents/utils.test.ts: atlas/metis resolution, buildAgent category,
override.category expansion (5 tests)
- plugin-handlers/config-handler.test.ts: ultrabrain config resolution
and fallback (2 tests)
- shared/agent-variant.test.ts: sisyphus chain variant and category
fallback (2 tests)
- shared/model-capability-guardrails.test.ts: built-in requirement
model ID assertion (1 test)
- tools/look-at/multimodal-fallback-chain.test.ts: multimodal-looker
hardcoded variant metadata (1 test)
- cli/config-manager/generate-omo-config.test.ts: sisyphus model and
fallback_models expectations (2 tests)
Updates test expectations across agent, cli, shared, plugin, and tools tests
to match gpt-5.5 as the new default for oracle, hephaestus, and deep agents.
Includes snapshot updates for model-fallback tests.

Now that each of these agents ships a native gpt-5.5 prompt variant,
their default OpenAI model is bumped from gpt-5.4 to gpt-5.5. The
gpt-5.4 entries are removed from the same-provider position in each
fallback chain (a single provider doesn't need both version entries -
if gpt-5.5 isn't available there, cross-provider fallback kicks in).
- oracle.fallbackChain: gpt-5.5 high (openai) -> gemini-3.1-pro -> claude -> glm
- hephaestus.fallbackChain: gpt-5.5 medium (openai only, requiresProvider)
- deep category.fallbackChain: gpt-5.5 medium -> claude -> gemini
- deep category.config: openai/gpt-5.5 medium
No changes to sisyphus, sisyphus-junior, ultrabrain, momus, or other
agents that still point at gpt-5.4; those stay on the shared regex-
based routing in the gpt-5-4 prompt family.
The previous description (41 words) told the LLM to write 'complete AST
nodes' but did not explain that regex syntax is the #1 failure mode. It
also shipped a bug: the Python example 'def $FUNC($$$):' had a trailing
colon that the hint system actively flags as wrong.
Extract descriptions into tool-descriptions.ts and rewrite:
- Open with 'This is NOT regex' so the constraint is unmissable
- List the four regex patterns that do not work (|, .*, \\w, [a-z])
with the corrective action for each
- Tell the LLM to switch to grep when the pattern is text-shaped
- Fix the Python example (no trailing colon) and add Go and Rust rows
since the failing reports came from Go codebases
- Shorten the pattern-param description with the same anti-regex list
Also harden the LSP reference for the new test files using the
bun-types triple-slash directive already used elsewhere.
LLMs frequently call ast_grep_search with regex-style patterns like
'func.*build|BuildMode|projectReferences' instead of AST patterns. The
search silently returns zero matches with no useful feedback, so the
model retries with a different regex-shaped pattern and loops.
Extract hint generation into pattern-hints.ts and add detectors for the
four dominant misuse modes:
- regex escapes (\\w, \\d, \\s, \\b)
- character-class ranges ([a-z], [0-9])
- regex wildcards (.* .+) with no meta-vars
- pure alternation (foo|bar|baz with no structural syntax)
Heuristics are designed to be safe on valid AST patterns: bitwise OR
'$A | $B' and Rust closures '|x| x + 1' are not flagged. Language-
specific shape hints (trailing-colon Python, body-less JS/TS/Go/Rust
functions) are preserved and extended to Go and Rust.
Tighten resolve-metadata-model runtime guards, tidy tool-argument-preparation
subagent-type override logging, and trim a redundant literal in the
metadata-model-unification test. Behavior preserved (328 tests pass).
Strip obvious comments, over-defensive guards, and dead branches across
the five delegate-task executor files while preserving all metadata
propagation behavior added in prior commits. Regression tests remain
green (328 pass / 0 fail).
The execute field with { task_id, task_dir } was defined but never referenced anywhere in the codebase. Removing dead code simplifies the type surface and prevents accidental future misuse.
