Avoid saturating before division.
requested_sample_capacity can return 922 instead of 922337 for average_window_sec = u64::MAX and interval_ms = 20_000_000_000_000_000. The CLI can therefore accept a request above MAX_SAMPLE_CAPACITY, and StatisticsEngine::new uses the under-reported value for max_samples.
Compute the product in u128 before division, and add a regression test.

Linux netlink dump NLM_F_DUMP_INTR NLMSG_DONE nonzero terminal status nlmsg_flags authoritative documentation
💡 Result:
In Linux netlink, the NLM_F_DUMP_INTR flag is used to signal that a dump operation was interrupted and may be incomplete or inconsistent [1][2]. Key Technical Details: 1. Flag Purpose: The kernel sets NLM_F_DUMP_INTR on a message in a dump sequence (including the final NLMSG_DONE message) if the state being dumped has changed during the operation, potentially leading to missing objects or inconsistent data [1][3]. 2. Handling in Userspace: When userspace encounters this flag, the authoritative recommendation is to retry the entire dump operation [1][3]. Some high-level libraries (like the Go vishvananda/netlink package) handle this by returning a specific error (e.g., ErrDumpInterrupted) to signify the interruption, which signals that the caller should initiate a retry [4][5]. 3. Relation to NLMSG_DONE: The NLMSG_DONE message marks the formal end of a multipart dump message sequence [1][2]. It is separate from the NLM_F_DUMP_INTR flag, though the flag can be present on the NLMSG_DONE message itself [1][2]. 4. Nonzero Terminal Status: While NLMSG_DONE typically marks a successful conclusion, it can carry return codes. Historically, and depending on the implementation, the payload of an NLMSG_DONE message may contain an integer representing a status or error code (often 0 for success, or a nonzero value if an error occurred during the dump) [1][6]. Applications should check the payload of NLMSG_DONE to determine if the dump terminated with an error, separate from the status of the consistency flag (NLM_F_DUMP_INTR) [1][5]. In summary, userspace applications must check for the NLM_F_DUMP_INTR flag on received messages to ensure data integrity and inspect the payload of the NLMSG_DONE message to verify the terminal status of the dump operation [1][5].

Reject interrupted or failed dump completion.
NLMSG_DONE sets completed without checking nlmsg_flags or its terminal status. If Linux marks the dump with NLM_F_DUMP_INTR or returns a nonzero status, netlink_collect can return an incomplete interface map through collector.rs:179. Accept completion only when the dump is not interrupted and its terminal status is zero.

curl --retry-all-errors POST request retry behavior official documentation
💡 Result:
The --retry-all-errors option in curl is designed to make curl treat all transfer failures as reasons to retry [1]. It must be used in conjunction with the --retry option, which specifies the maximum number of retry attempts [2][1]. Key behaviors and considerations include: - Scope: It instructs curl to retry on any error [2][1]. However, it is important to note that curl does not inherently consider HTTP response status codes (like 4xx or 5xx) as transfer errors [2][3]. By default, if an HTTP request completes and receives a response—even an error code—curl considers the transfer successful [2][3]. - HTTP Error Handling: To force curl to treat HTTP status code errors as failures eligible for retry, you must combine --retry-all-errors with the --fail option [2][4]. The --fail option tells curl to return a non-zero exit code if an HTTP server response indicates an error [2][5]. - Risk of Side Effects: This option is described as a "sledgehammer" for retries [2][6]. Because it retries everything, there is a risk of unintended consequences, such as sending duplicate data (e.g., in a POST request) or receiving duplicate data [2][6]. - Limitations: It should not be used with redirected input or output (such as piping data or redirecting to a file), as curl may not be able to correctly reset the state, potentially leading to incomplete or duplicated data being processed [2]. In summary, for a POST request where you want to retry on both network-level failures and HTTP-level error responses, the recommended approach is: curl --retry 5 --retry-all-errors --fail -X POST https://example.com/api [4]

Avoid replaying non-idempotent Gitee POST requests.
--retry-all-errors can resend the tag, release, and asset-upload POST requests after a transfer failure. A request can be accepted before the response is lost. Repeated requests can duplicate assets or leave tag and release creation ambiguous.
Reconcile resource state after an uncertain request, or do not retry these POST requests.
