+- `calls`: accepted tool calls with normalized tool names.
+- `sawToolCallSyntax`: true when tool-call-like syntax is detected (`tool_calls`, `<tool_call>`, `<function_call>`, `<invoke>`) or a valid call is parsed.
+- `rejectedByPolicy`: true when parser extracted call syntax but all calls are rejected by allow-list policy.
+- `rejectedToolNames`: de-duplicated rejected tool names in first-seen order.
+
+## Parse pipeline
+
+1. Strip fenced code blocks for non-standalone parsing.
+2. Build candidates from:
+   - full text,
+   - fenced JSON snippets,
+   - extracted JSON objects around `tool_calls`,
+   - first `{` to last `}` object slice.
+3. Parse each candidate in order:
+   - JSON payload parser (`tool_calls`, list, single call object),
+   - XML/Markup parser (`<tool_call>`, `<function_call>`, `<invoke>`; supports attributes + nested fields),
+   - Text KV fallback parser (`function.name: <name>` ... `function.arguments: {json}`).
+4. Stop at first candidate that yields at least one call.
+
+## Name normalization policy
+
+When matching parsed names against configured tools:
+
+1. exact match,
+2. case-insensitive match,
+3. namespace tail match (`a.b.c` => `c`),
+4. loose alnum match (remove non `[a-z0-9]`, compare).
+
+## Standalone mode
+
+Standalone mode (`ParseStandaloneToolCallsDetailed`) parses the whole input directly (no candidate slicing), while still applying:
+
+- example-context guard,
+- JSON then markup fallback,
+- the same allow-list normalization policy.

-## Notes
-
- This file records a historical baseline for refactor process tracking.
- It is not intended to represent the current repository HEAD.
- Frontend manual smoke for phase 6 still requires human execution and sign-off.

-# Refactor Line Gate
-
-## Rules
-
-1. Production file default upper bound: `<= 300` lines.
-2. Entry/facade files upper bound: `<= 120` lines.
-3. Scope is limited to target files in `plans/refactor-line-gate-targets.txt`.
-4. Test files are out of scope for this gate.
-
-## Command
-
-```bash
-./tests/scripts/check-refactor-line-gate.sh
-```
-
-## Naming Note
-
- Original split plan used `internal/admin/handler_accounts_test.go` for account probing logic.
- In Go, `*_test.go` files are test-only compilation units and cannot host production handlers.
- The production file is implemented as `internal/admin/handler_accounts_testing.go`.
