🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
A corrupt state file blocks all imports.
JSON.parse raises SyntaxError for a truncated or malformed file. The catch block only handles ENOENT and rethrows everything else, so /honcho:import fails until the user deletes the file manually. Treat unparsable state as empty state.

Stamp first-time TUI setup with new-install defaults.
When saveSettings creates hosts.opencode, it omits observationMode and removeUserPrefix. Because ensureSharedGlobalSettings leaves an existing config unchanged, the next runtime uses "directional" and false, and the setup confirmation opens the upgrade prompt. Set "unified" and true only when hosts.opencode did not already exist. Preserve existing unstamped hosts so upgrades still prompt for a choice.

ECMAScript Date.prototype.toISOString invalid Date RangeError Date Time Clip finite timestamp range authoritative specification
💡 Result:
In the ECMAScript specification, Date.prototype.toISOString is required to throw a RangeError exception if the date value of the Date object is not a finite number [1][2][3]. The technical details regarding this behavior are as follows: 1. Time Value Range: The ECMAScript specification defines a valid time value as a finite Number representing an instant in time to millisecond precision [4][5]. This supported range is exactly -8,640,000,000,000,000 to 8,640,000,000,000,000 milliseconds relative to the epoch (January 1, 1970, UTC) [4][5]. This range corresponds to ±100,000,000 days, or approximately 273,790 years, from the epoch [5][6]. 2. Invalid Date State: Any Date object that attempts to represent a time outside of this finite range, or is otherwise initialized with an invalid date string, will hold a time value of NaN (Not-a-Number) [7][6]. 3. RangeError Requirement: When Date.prototype.toISOString is called on a Date object, the internal algorithm checks if the time value is finite [2][3]. If the value is NaN or otherwise non-finite, the specification requires the implementation to throw a RangeError [1][7]. While older implementations may have behaved differently, modern ECMAScript engines conform to this requirement to ensure standard behavior [2][3]. In summary, the RangeError is thrown because toISOString requires a finite, valid timestamp to construct a compliant ISO 8601 string; non-finite values (like NaN or Infinity) cannot be represented in this format [1][7][2].

Preserve the invalid-timestamp fallback.
Number.isFinite(value) does not guarantee a valid Date. A finite value outside JavaScript’s supported date range makes toISOString() throw RangeError, which can abort extractImportMessages().
Check the constructed date before calling toISOString().

the resulting date is invalid or outside JavaScript’s supported range. Preserve

does opencode recommend this as a way to query session data for plugins? it may be possible via a plugin sdk they expose? https://opencode.ai/docs/plugins/#typescript-support
