Trusted uv transient download retry boundary + +## Decision + +The central coverage materializer downloads one checksum-pinned uv archive from one literal Astral HTTPS URL. It now performs at most **three total attempts**, separated by deterministic delays of one and two seconds, only for bounded transport failures: + +- connection-level `urllib.error.URLError` or `OSError` failures; +- HTTP 408, 429, 500, 502, 503, and 504 responses. + +The fixed `GET` is safe and idempotent, so a bounded retry does not mutate remote or repository state. The retry loop does not follow redirects, enable proxies, change the release URL, use repository-controlled headers, or accept an unverified payload. + +## Fail-closed exclusions + +The following conditions are never retried: + +- permanent HTTP failures such as 400, 401, 403, or 404; +- redirect attempts or a final origin/port outside the fixed Astral HTTPS origin; +- an oversized archive; +- SHA-256 mismatch; +- malformed archive members, incorrect executable size or type, unsupported runner architecture, or unexpected uv version; +- offline export, exact-pin grammar, Git-tree, TOML, or workspace-boundary failures. + +Retry exhaustion reports only the bounded exception class or numeric HTTP status and the attempt count. It does not include URLs, response bodies, headers, credentials, or arbitrary exception text. + +## Incident evidence + +Central OpenCode coverage run `31002427460` for `ContextualWisdomLab/newsdom-api#524` reached the exact trusted-uv materialization stage and failed with `trusted uv archive download failed: HTTPError`. The source PR changed only `AGENTS.md`; all repository-local checks were successful. A later workflow in the same operating window downloaded the pinned uv release successfully, supporting a bounded transient-retry response rather than weakening the immutable bootstrap or bypassing coverage. + +## Verification contract + +Permanent tests require: + +- a transient HTTP 503 followed by a valid response succeeds after one one-second delay; +- a connection-level `URLError` receives the same bounded retry; +- three persistent transient failures stop after exactly three attempts and delays of one and two seconds; +- an HTTP 404 fails immediately without sleeping; +- the literal URL, no-proxy opener, redirect rejection, final-origin validation, repeated bounded reads, maximum size, checksum, archive member, executable version, Python compatibility, offline export, full SHA-256 grammar, 100% statement/branch coverage, and production docstrings remain unchanged. + +## MSA and operational boundary + +This retry belongs to the organization-owned coverage control plane because every leaf repository consumes the same trusted bootstrap. Leaf repositories such as NewsDOM and naruon must not duplicate a downloader or weaken their review gates. If all three attempts fail, the current-head review remains fail-closed and publishes actionable coverage evidence; no approval or merge is synthesized. + +## Rollback + +Rollback removes the retry constants and loop while retaining all immutable-source, no-proxy, no-redirect, bounded-read, checksum, archive, executable-version, and offline-export controls. Operators may also set the delay tuple to empty in a reviewed change to restore one attempt. Increasing attempts or delays requires a separate availability and runner-budget review. + +## References + +Fielding, R. T., Nottingham, M., & Reschke, J. (2022). *HTTP semantics* (RFC 9110).

process and 5-second fake-sleep budgets so exact-head policy evidence completes inside the existing job limit without changing production Strix scanner timeouts, providers, credentials, or review semantics. - Allowed commas and ASCII parentheses in the bounded Strix changed-file path policy so legal tracked Packrat fixtures can receive exact-head security analysis, while rejecting raw `..` components before normalization and keeping controls, backslashes, whitespace ambiguity, and shell punctuation fail-closed. - Bound each review-agent invocation key to the wrapper's complete canonical payload, including the base branch and requesting actor; altered fields with a valid-format key now fail before durable-leader election or forwarding, and wrapper write permission is job-scoped. +- Retried the fixed, checksum-pinned trusted uv archive download at most twice after transient transport, 408, 429, or 5xx availability failures while keeping redirects, permanent 4xx responses, origin drift, size, checksum, archive, and version failures immediately fail-closed. - Bound both trusted-uv quality jobs to `github.event.pull_request.head.sha` and added a permanent two-checkout regression contract so exact-head compatibility, coverage, docstring, and compilation claims cannot silently measure GitHub's generated pull-request merge revision. - Made Strix treat only a single LiteLLM provider-error line containing NVIDIA NIM context and model-catalog 404 evidence as cross-model fallback evidence, rejecting cross-line signal assembly and provider-like target source literals; moved the public default to Nemotron 3 Super 120B and added a second NVIDIA hosted candidate before GitHub Models without neutralizing reported vulnerabilities. - Bind reusable scheduler implementation to the validated called-workflow repository, SHA, ref, and file path, and verify the checked-out commit before executing privileged scheduler logic. diff --git a/scripts/ci/apply_trusted_uv_retry_once.py

- ## Decision - - The central coverage materializer downloads one checksum-pinned uv archive from one literal Astral HTTPS URL. It performs at most **three total attempts**, separated by deterministic delays of one and two seconds, only for a closed set of availability failures: - - - HTTP 408, 425, 429, 500, 502, 503, and 504; - - timeout; - - temporary DNS (`EAI_AGAIN`); - - connection aborted, refused, or reset; and - - explicit host or network down, reset, or unreachable errors. - - Every attempt reuses the same literal URL and exact timeout. Bytes from a failed read are scoped to that attempt and discarded before retry. - - ## Fail-closed exclusions - - Certificate verification and all other TLS failures, permanent DNS failures, malformed `URLError.reason`, local permission failures, unclassified `OSError` values, permanent HTTP responses, redirects, origin drift, oversized payloads, checksum mismatch, malformed archive members, unsupported runners, unexpected uv versions, and offline-export or lock-grammar failures are never retried. - - Diagnostics expose only a bounded HTTP status, transport errno, or exception class and attempt count. They never include URL text, headers, response bodies, credentials, or arbitrary exception messages. - - ## Incident evidence - - Central OpenCode coverage run `31002427460` for `ContextualWisdomLab/newsdom-api#524` reached the exact trusted-uv materialization stage and failed with a bounded HTTP failure. A later run in the same operating window downloaded the same pinned release successfully. This supports a bounded retry without weakening immutable-source, checksum, or coverage gates. - - ## Verification contract - - Permanent tests prove the exact retryable HTTP set, immediate permanent-HTTP failure, temporary and permanent DNS separation, timeout and connection-reset retry, TLS and unclassified-local-error rejection, malformed reason rejection, exact request reuse, retry exhaustion, and disposal of partial bytes. Existing no-proxy, no-redirect, origin, size, SHA-256, archive-member, executable-version, offline export, exact-pin, 100% statement/branch coverage, and 100% production-docstring gates remain mandatory. - - ## MSA and operational boundary - - This behavior belongs to the organization-owned coverage control plane. Leaf repositories must not duplicate the downloader or weaken review gates. Exhaustion leaves current-head review fail-closed and cannot synthesize approval. - - ## Rollback - - Rollback removes the retry classifier, constants, and loop while retaining every immutable-source and integrity control. Increasing the closed status/errno sets, attempt count, or delays requires a separate reviewed change. - - ## References - - Fielding, R. T., Nottingham, M., & Reschke, J.

Restricted trusted uv retries to HTTP 408/425/429/500/502/503/504 and explicitly classified temporary DNS, timeout, connection, host, or network failures; every retry reuses the immutable request contract and discards failed-attempt bytes, while TLS, permanent DNS, malformed, and unclassified local errors fail after one attempt. - Bound both trusted-uv quality jobs to `github.event.pull_request.head.sha` and added a permanent two-checkout regression contract so exact-head compatibility, coverage, docstring, and compilation claims cannot silently measure GitHub's generated pull-request merge revision. -

Partial bytes read before a transie The base-commit reader resolves `git` with `shutil.which("git", path=os.defpath)` and accepts only an absolute result. The ambient process `PATH` cannot select the executable; missing or relative resolution fails before any repository command runs. +## Descriptor-pinned output boundary + +The generated-lock output path is treated as an untrusted namespace rather than as a stable object. Every directory component is created or opened relative to an already-open parent descriptor with `O_DIRECTORY`, `O_NOFOLLOW`, and `O_CLOEXEC`. The materializer compares the path entry's device and inode to the pinned descriptor immediately after open and again before reporting success. Removing, replacing, or redirecting the output pathname therefore fails closed; subsequent writes never re-resolve that mutable pathname. + +Generated requirements and manifests are opened relative to the pinned output directory. A new file requires `O_CREAT | O_EXCL | O_NOFOLLOW`; a rerun may reopen only an existing singly linked regular file. Symbolic links, hard links, directories, FIFOs, and other special files are rejected before truncation. Each write is bounded by forward-progress checks, synchronized with `fsync`, and revalidated against the pinned file descriptor before the directory itself is synchronized and revalidated. + +This contract intentionally uses the POSIX descriptor-relative interface represented by `openat()` and Python's `dir_fd` operations. It prevents the check-then-use gap reported against the earlier `Path.exists()`/`Path.is_symlink()` followed by `Path.mkdir()` sequence. The central GitHub runner is Linux; a platform that does not provide the required no-follow descriptor flags fails at import or execution rather than silently falling back to pathname-based writes. + ## Incident evidence Central OpenCode coverage run `31002427460` for `ContextualWisdomLab/newsdom-api#524` reached the exact trusted-uv materialization stage and failed with `trusted uv archive download failed: HTTPError`. The source PR changed only `AGENTS.md`; all repository-local checks were successful. A later workflow in the same operating window downloaded the pinned uv release successfully, supporting a bounded transient-retry response rather than weakening the immutable bootstrap or bypassing coverage. The same failure class later blocked exact-head OpenCode coverage for `ContextualWisdomLab/pg-llm-batch#53` in central workflow run `31022108085`. Repository-local CI, security, and SAST checks passed on that exact product head, while trusted uv archive materialization failed before PR-controlled tests ran. +Exact-head Strix run `31076540331` for organization control-plane PR `ContextualWisdomLab/.github#790` identified a medium-severity time-of-check/time-of-use race between output-directory symlink inspection and directory creation. The finding was valid rather than stale or infrastructure-only. Test-first commit `a1dcc679c1767f7e806793d7c0225a1342a9a875` captured intermediate symlink, pathname removal and replacement, generated-file symlink and hard-link, post-open swap, zero-progress write, and root-output regressions before descriptor-pinned production remediation. + ## Verification contract Permanent tests require: @@ -46,18 +56,25 @@ Permanent tests require: - certificate verification, permanent DNS, malformed transport reasons, and unclassified local errors fail after one attempt and no sleep; - persistent transient failures stop after exactly three attempts and delays of one and two seconds; - every attempt reuses the literal trusted URL and exact timeout; -- partial bytes from a failed response are absent from the next attempt; and +- partial bytes from a failed response are absent from the next attempt; +- every output path component is opened without following symlinks and remains bound to the pinned descriptor; +- output-path removal or inode replacement fails closed after descriptor-relative writes; +- generated-file symlinks and multiply linked files are rejected before mutation; +- a singly linked regular generated file can be safely refreshed on a rerun; +- a post-open generated-file path swap and a zero-progress descriptor write fail closed; and - the no-proxy opener, redirect rejection, final-origin validation, repeated bounded reads, maximum size, checksum, archive member, executable version, Python compatibility, offline export, full SHA-256 grammar, 100% statement and branch coverage, and production docstrings remain unchanged.
