Conversation
The suffix cursor was keyed by the full sanitized base, but a candidate keeps at most MAX_TOOL_CALL_ID_LENGTH - 2 characters of it — longer suffixes only truncate deeper. Distinct ids agreeing on that prefix therefore produce the same candidate sequence while each restarting the search at -2, so M prefix-sharing ids emitted twice still cost ~M^2/2 occupied-set probes. Key the cursor by the post-truncation prefix — the actual collision domain — so all ids sharing it resume the same search. The occupied-set check still decides acceptance, keeping emitted ids unique and within the 64-char bound. Regression test: 1,000 conforming 64-char ids plus 500 overlength non-conforming ids, all sharing the first 62 characters and each emitted twice, stay under 10k probes (was ~1.13M before).

CodeBuddy and Qoder share the coding-agent stream-json parser. It retained every tool_use argument fragment until the block closed without charging the request's translator budget, and the per-turn call ceiling was checked only after a block had been allocated and only when a CodeBuddy tool bridge was present. The parser now owns one admission check before allocation (16 starts, or the bridge's tighter limit), charges retained tool IDs, names and argument fragments to the shared budget, and releases every reservation on close, EOF, protocol error and abort. Budget overflow reports translation_buffer_limit and the call ceiling reports tool_call_limit. createToolCallIdReminter probed -2, -3, ... from the start for each repeat of an ID, which made a long run of duplicates quadratic, and siblings whose retained prefixes diverged at -9 could converge at -10. The reminter now keeps a next-suffix cursor per (suffix width, retained prefix) group, so no occupied candidate is probed twice. Carries #6081 and reimplements #6083.

The cursor keyed on the fixed 62-char base prefix, but a longer suffix keeps fewer prefix characters in the candidate (-10 keeps 61, -100 keeps 60). Distinct 62-char prefixes sharing those shorter characters emit identical candidates yet restarted separate searches at the same occupied slots — quadratic probes again, exactly what the shared-cursor fix set out to close. The domain is now the candidate's own kept prefix, re-derived as the suffix widens. Crossing a width boundary resumes at the shorter domain's cursor — never backwards, since every probe below it is known-occupied there — and records the next suffix on that same domain.

Addressed the shared-cursor finding in 3f8f85c: the resume cursor now lives on the candidate's own kept prefix — the collision domain actually shrinks as the suffix widens (-10 keeps 61 chars, -100 keeps 60), so distinct 62-char bases sharing those characters resume one search instead of restarting per base. A new regression test emits 300 ids sharing a 60-char prefix for 35 rounds (into the -<3-digit> suffix band) and asserts bounded probes (20,700 measured for 10,500 emissions). |

dev's lidge-jun#6081/lidge-jun#6083 moved the ceiling and the budget for coding-agent tool state into the shared parser, which is the same state this adapter reads through its capture-only bridge. Two halves had to follow, the same class as lidge-jun#6022 and lidge-jun#5945 before them. The parser now enforces its ceiling (16 starts, or a bridge's tighter limit) before it allocates the block and reports the refusal through `toolCallLimitExceeded`; the parse state carries the bridge's limit for that. This adapter only compared `toolBlockStarts` after the fact, so a start the parser refused before allocation left no trace: the dropped call never entered `toolBlockStarts`, the completeness invariants therefore saw starts and completions as equal, and a turn could end as a successful completion with a call missing. The parser also charges retained tool identity and argument fragments to the request's translator budget and releases them on close, EOF, protocol error and abort. The state now carries `incoming.translatorBudget`, `releaseOpenToolBlocks(state)` runs on every exit path, and a budget overflow keeps its own `translation_buffer_limit` code instead of being flattened into the generic SDK error the surrounding branch reports. Two tests cover it: a turn without a bridge that passes the shared ceiling fails closed, and a retained argument past a small per-call budget surfaces the budget's code. Reverting the adapter fails four tests, those two and the two that pinned the cap before, and the existing cap tests now pass through the parser's own admission rather than a parallel count.
