* perf(terminal): drop the JSON structural pre-scan from the history read path readTerminalHistoryJson/Async walked every character of checkpoint.json in interpreted JS before handing the same string to native JSON.parse. On a 26.8MB checkpoint that scan measured 63-330ms — 2.7-12x the JSON.parse it guards, and 57% of the whole read path — all of it synchronous main-thread work. readTerminalHistoryJsonAsync exists so cold-restore reads do not block the main thread; running the scan inline right after the async read defeated its own stated purpose. The scan also had a correctness cost: TERMINAL_HISTORY_JSON_MAX_STRUCTURAL_TOKENS was 1_000_000, and oscLinks is unbounded at ~10 structural tokens per link, so roughly 100k OSC-8 hyperlinks tripped the assert, history-reader swallowed the throw to a null checkpoint, and the terminal restored blank — the same user-visible loss #10479 just fixed for the byte cap. checkpoint.json and meta.json are our own SerializeAddon output, not untrusted input: the byte cap still bounds the read, and a corrupt file fails JSON.parse into the same catch. The shared helper stays for the call sites that do handle untrusted JSON. * test(terminal): pin iterative JSON.parse for the dropped nesting-depth cap The retired pre-scan enforced two limits; the new tests only covered the structural-token half. Dropping the 128-level nesting cap is safe solely because V8 parses JSON iteratively — depth costs heap, not stack — so a deeply nested checkpoint parses instead of overflowing. Verified: 10M-deep arrays and objects parse without throwing on V8 14.6. That property is an engine guarantee this code now silently depends on, and a recursive parser would abort the daemon outright rather than throw into the callers' catch. The test fails on main with "JSON nesting exceeds 128 levels" and costs 4ms. * docs(terminal): drop the rot-prone benchmark figure from the reader comment Keeps the durable rationale for skipping the pre-scan (self-authored input, byte cap still bounds the read, corrupt files land in the callers' existing catch) and moves the "~57% of the read path" measurement to the PR body, where it cannot go stale against a later change to this path. Addresses the CodeRabbit comment-length nitpick against the repo's one-line-if-possible comment guideline.
