patch.py fails on v2.1.87 — db8 pattern hits wrong occurrence, TTL function renamed

[arsinoeii]

Version

2.1.87 (npm @anthropic-ai/claude-code@2.1.87)

Problem

patch.py exits with:

Patch 1 FAILED: found hook_additional_context but couldn't locate insertion point

The critical db8 patch fails even though the target code exists.

Root cause

Patch 1 (db8): The semantic search does source.find('"hook_additional_context"'), which hits the first occurrence in the file — an object constructor like:

vq({type:"hook_additional_context", content:..., hookName:"SessionStart", ...})

There's no return!1} within 300 chars of that. The actual filter function appears much later:

function GH6(q){
  if(q.type==="progress")return!1;
  if(q.type==="attachment"&&M57()!=="ant"){
    if(q.attachment.type==="hook_additional_context"&&n6(process.env.CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT))return!0;
    return!1
  }
  return!0
}

Patch 2 (TTL): The function was renamed from sjY to Eyz in this version. Semantic search also fails here.

Patch 1b: Already present in 2.1.87 — no action needed.

Fix

For Patch 1, search for the more specific string that includes CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT — it only appears in the filter function, not in constructors:

old1 = (
    'if(q.attachment.type==="hook_additional_context"'
    '&&n6(process.env.CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT))return!0;'
    'return!1}'
)

Note: variable names differ from 2.1.81 — parameter is q (not A), helper is n6 (not a6), provider check is M57 (not QA). The regex strategy should handle this if it searches for CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT as the anchor rather than hook_additional_context.

For Patch 2, the TTL function is now Eyz:

old2 = 'function Eyz(q){if(V7()==="bedrock"'
new2 = 'function Eyz(q){return!0;if(V7()==="bedrock"'

The semantic search (find ttl:"1h", walk back to function boundary) should work if the regex fallback is fixed.

Suggestion

For Patch 1's semantic search, anchor on CLAUDE_CODE_SAVE_HOOK_ADDITIONAL_CONTEXT instead of hook_additional_context — it's unique to the filter function and won't match constructors.
