feat: Report the hot-reload outcome and per-kind totals as fields and settle the message after a fallback compile - #3177

…ck compile A successful fallback compile reloads the domain, so the reload's own verdict, its Auto Refresh hold flag and the hold sentence in Message no longer describe the Editor. The CLI now writes Outcome ReplacedByCompile, turns AutoRefreshHeld false when the response has it, and removes the sentence the Editor reported in AutoRefreshHoldMessage from the end of Message before appending the compile sentence, so the CLI keeps no copy of the sentence. A failed compile leaves the reload's state as it was, and a response from an older package without the new fields still gets Outcome.
Whether an edit took effect could only be read by combining Success, PatchedTotal, ActivePatchTotal, CompileFallback and Message. The new decision answers it in one word from the rows of the requested files: Applied, PartiallyApplied, NothingApplied, NothingToApply, or Failed. Rows of sibling files the run re-applied on its own are left out, as the message already does, while a Failed row decides wherever it is because Success turns false for it. ReplacedByCompile is listed for the value the CLI writes after a successful fallback compile.
The Added, Skipped and Failed counts were only readable from the Message sentence, so callers guessed field names that do not exist. An apply response now carries Outcome and SkippedTotal, AddedTotal, FailedTotal, AlreadyActiveTotal and StaleTotal, which count every Methods row like PatchedTotal does. AutoRefreshHoldMessage holds the hold sentence this run appended to Message, so the CLI can remove exactly that sentence after a successful fallback compile without keeping its own copy. --status, --revert-all and validation failures leave Outcome empty, which omits it.
The reference opened with a long list of fields, none of which said how to tell whether an edit took effect. It now starts with a short section that reads Outcome first and says what each value means, and the field list describes Outcome, the per-kind totals and AutoRefreshHoldMessage. Message, Compile and CompileFallbackNote now say that a successful fallback compile sets Outcome to ReplacedByCompile, turns AutoRefreshHeld false and removes the hold sentence. The generated skill copies are regenerated from the source.

📝 WalkthroughWalkthroughThe hot-reload response now reports apply outcomes and per-kind method totals. After a successful fallback compile, the project runner updates the outcome, Auto Refresh hold state, and message. Tests and output references cover these response behaviors.

Qualify the Applied advice. An Added Unity message can report Applied while its LifecycleNote says the engine will not invoke it until compilation. “Nothing else to do” can therefore stop a caller before the message works.

| - `Failed` — at least one `Failed` row, so `Success` is `false` — unless a fallback compile then succeeded, which turns the whole answer into `ReplacedByCompile`. | ||
| - `ReplacedByCompile` — a fallback compile ran in this same command and succeeded (`Compile` holds its response): every edit is compiled in, and `Success` is the compile's. The compile reloaded the domain, so none of this run's patches survive; the totals and `Methods[]` describe the reload that ran before the compile — read `--status` for the state after it. | ||
|
|
||
| `Outcome` is written on apply runs only and judges the files you asked about; rows of a sibling file the run re-applied on its own (`ReappliedFromSibling: true`) do not change it, while `CompileFallback` may still be `Requested` for a retried sibling row. The totals beside it (`PatchedTotal`, `SkippedTotal`, `AddedTotal`, `FailedTotal`, `AlreadyActiveTotal`, `StaleTotal`) count every `Methods[]` row by `Kind`, siblings included. |

State the sibling Failed-row exception. HotReloadApplyOutcome.Decide excludes sibling live and Skipped rows, but any sibling Failed row makes Outcome equal Failed. The unconditional exclusion contradicts that behavior. (github.com)

A review found three changes to the new outcome code that every test still passed: - deciding the outcome from the method failures alone, which answers NothingToApply or Applied for a run whose only failure is a refused type declaration; - leaving Introduced or AlreadyActive out of the live type kinds, because one test passed both kinds in one list; - dropping or swapping the Skipped, Added, AlreadyActive and Stale totals, because they were asserted only as 0 or as equal values. The type-refusal tests now assert Outcome Failed, the type kinds are decided one at a time, and one response test gives every kind a different row count.

Summary
Outcome, whether the edits of the requested files are live, and counts every outcome kind in its own field.OutcomebecomesReplacedByCompile,AutoRefreshHeldturnsfalse, and the stale "Auto Refresh is held" sentence is removed fromMessage.User Impact
Successwastrueeven when nothing was applied, so telling whether an edit took effect meant combiningPatchedTotal,ActivePatchTotal,CompileFallbackandMessage. The Added, Skipped and Failed counts existed only inside theMessagesentence, so agents guessed fields such asAddedTotalorSkippedTotalthat did not exist. After a successful fallback compile,Messagestill told the caller to runuloop compileto release a hold the compile had already released.Outcomefirst; the totals are plain numbers; a successful fallback compile leaves a response that matches the Editor. The output reference opens with a short "Is my edit live?" section.Changes
