exactly-once operations never report a false failure after mutation.

|

#### Mutation success receipts
|
||||
|
||||
Proposal, preview, and canonical-application MCP mutations now declare an internal response policy.
|
||||
Before runtime validation or mutation, the service proves that a minimum receipt containing the
|
||||
actual input identity and fixed-length hash fields fits the configured output limit. If it cannot,
|
||||
the operation returns a preflight size error with `mutation_committed = false` and does not call the
|
||||
mutation.
|
||||
|
||||
Small results retain the existing full payload. Oversized successful results become a version-1
|
||||
compact receipt that preserves exact changeset identity, hash, workflow scalars, and lifecycle
|
||||
state while omitting full operations. Application receipts also preserve changed-source counts and
|
||||
derived-refresh status/counts. If the compact form is still too large, the service returns the
|
||||
minimum receipt proven by preflight. It never converts committed success into a post-write size
|
||||
failure.
|
||||
|
||||
End-to-end MCP tests exercise two large hash-chained appends followed by canonical application.
|
||||
Each response stays within 1,600 compact JSON characters, exposes the new exact hash, and reports
|
||||
committed success. A separate 700-character preflight test proves the callback and changeset file
|
||||
are never created. Changeset lifecycle receipts now obey the configured changeset byte limit on
|
||||
both write and read.
|
||||
|
||||
#### Bounded indexed retrieval

||||
|
||||
Search, metadata filtering, backlinks, dependency traversal, and impact traversal now query one

Successful mutations return their existing full result while it fits the configured output limit.
|
||||
Before any proposal, preview, or canonical mutation, the server verifies that a minimum exact
|
||||
success receipt can fit. An impossible receipt fails with `result_too_large`,
|
||||
`stage = "preflight"`, and `mutation_committed = false` before calling the mutation. If a successful
|
||||
full result is too large, the server returns a version-1 compact receipt containing the exact
|
||||
changeset ID and hash plus the operation outcome. It may fall back to a preflight-guaranteed
|
||||
minimum receipt, but it never replaces a committed mutation with a failure response. Direct Python
|
||||
and CLI integrations retain their detailed return values.

MCP mutations are preflighted against the configured response limit. Small mutations keep their
