Claude works -# in a sandbox with no service PAT, GitHub write permission, OIDC token, or -# general network access. It may edit only the untrusted `pr-head/` worktree and -# exports a bounded patch plus a structured what/why report as a short-lived -# artifact. It never commits, pushes, comments, or authorizes CI. -# -# PUBLISH -# ------- -# `publish` starts on a fresh runner and treats the artifact as untrusted. Fixed -# shell code reconstructs the same baseline and rejects out-of-scope paths, -# control files, modify/delete or other non-three-stage conflicts, -# binary/create/delete/rename/mode changes, unsafe path/report text, large -# patches, unresolved conflicts, and unexpected result trees. -# -# If this is the first change in the session, fixed code creates one signed-off -# `svcnvidia-nemo-ci` commit and uses an ordinary push to the contributor's fork -# branch. If an earlier attempt already created that commit, fixed code verifies -# its exact SHA, bot identity, message, Signed-off-by trailer, and original -# parent list, then preserves its author date while amending. The only -# non-fast-forward operation is an exact -# `--force-with-lease=:` with no -# fallback, so it cannot replace contributor work or a concurrent update. -# PR-wide DCO failures do not block the session; contributor sign-offs remain -# the author's responsibility. -# -# After publication, PAT-scoped fixed steps post the sanitized service-account -# explanation with an author-directed DCO reminder, verify the live PR head, -# and ensure exact-SHA CI exists. When -# a new mirror/run is needed, they post `/ok to test `; copy-pr-bot -# then mirrors the current PR head to NVIDIA's `pull-request/` branch, which -# triggers `cicd-main.yml` in the NVIDIA repo. -# -# MONITOR AND OUTPUTS -# ------------------- -# `monitor` has read-only permissions. It accepts only the matching workflow, -# synthetic branch, event, and exact SHA. Green CI ends the session; only lint -# and ordinary non-GB200 unit failures return `actionable`; all other failures -# stop for manual handling. Outputs pass the current head, the session's bot -# commit SHA, CI run, and outcome to the next orchestrated attempt. -# -# TRUST BOUNDARY -# -------------- -# Secrets are mapped explicitly and the service PAT exists only in the fixed -# push, explanation, and CI-authorization steps. Structural validation cannot -# prove model-generated source or test code is semantically safe; the initiating -# maintainer command is the authorization to run that exact generated SHA. -name: Claude Fix Attempt - -on: - workflow_call: - inputs: - pr_number: - required: true - type: string - requester: - required: true - type: string - head_repo: - required: true - type: string - head_ref: - required: true - type: string - expected_head_sha: - required: true - type: string - original_head_sha: - required: true - type: string - service_commit_sha: - required: false - type: string - default: "" - base_ref: - required: true - type: string - base_sha: - required: true - type: string - steer_b64: - required: false - type: string - default: "" - previous_ci_run_id: - required: false - type: string - default: "" - attempt: - required: true - type: number - model: - required: true - type: string - secrets: - nvidia_inference_url: - required: true - nvidia_inference_key: - required: true - service_pat: - required: true - outputs: - created: - value: ${{ jobs.publish.outputs.created }} - sha: - value: ${{ jobs.publish.outputs.sha }} - service_commit_sha: - value: ${{ jobs.publish.outputs.service_commit_sha }} - outcome: - value: ${{ jobs.monitor.outputs.outcome }} - ci_run_id: - value: ${{ jobs.monitor.outputs.ci_run_id }} - ci_run_url: - value: ${{ jobs.monitor.outputs.ci_run_url }} - -permissions: {} - -jobs: - prepare: - name: Prepare Read-Only Claude Proposal - runs-on: ubuntu-latest - timeout-minutes: 90 - permissions: - actions: read - contents: read - issues: read - pull-requests: read - outputs: - baseline_tree: ${{ steps.merge.outputs.baseline_tree }} - needs_merge: ${{ steps.merge.outputs.needs_merge }} - artifact_name: ${{ steps.proposal.outputs.artifact_name }} - env: - GH_TOKEN: ${{ github.token }} - REPO: ${{ github.repository }} - PR_NUMBER: ${{ inputs.pr_number }} - HEAD_SHA: ${{ inputs.expected_head_sha }} - BASE_SHA: ${{ inputs.base_sha }} - BASE_REF: ${{ inputs.base_ref }} - CLAUDE_CODE_SUBPROCESS_ENV_SCRUB: "1" - steps: - - name: Checkout trusted base - uses: actions/checkout@df4cb1c069e1874edd31b4311f1884172cec0e10 # v6 - with: - ref: ${{ inputs.base_sha }} - persist-credentials: false - fetch-depth: 1 - - - name: Checkout immutable fork head - uses: actions/checkout@df4cb1c069e1874edd31b4311f1884172cec0e10 # v6 - with: - repository: ${{ inputs.head_repo }} - ref: ${{ inputs.expected_head_sha }} - path: pr-head - persist-credentials: false - fetch-depth: 0 - - - name: Materialize steering and prior failed logs - env: - STEER_B64: ${{ inputs.steer_b64 }} - PREVIOUS_RUN: ${{ inputs.previous_ci_run_id }} - shell: bash - run: | - set -euo pipefail - printf '%s' "$STEER_B64" | base64 --decode >.claude-fix-steer.txt - test "$(wc -c <.claude-fix-steer.txt)" -le 2000 - mkdir -p "$RUNNER_TEMP/claude-fix-ci" - if [[ -n "$PREVIOUS_RUN" ]]; then - [[ "$PREVIOUS_RUN" =~ ^[1-9][0-9]*$ ]] - run=$(gh api "repos/$REPO/actions/runs/$PREVIOUS_RUN") - test "$(jq -r '.head_sha' <<<"$run")" = "$HEAD_SHA" - test "$(jq -r '.path' <<<"$run")" = ".github/workflows/cicd-main.yml" - test "$(jq -r '.status' <<<"$run")" = completed - test "$(jq -r '.conclusion' <<<"$run")" = failure - log_error="$RUNNER_TEMP/claude-fix-ci/failed.error" - if !

It also -# verifies the exact command, requester write access, open fork PR, enabled -# maintainer edits, and a non-default/non-protected fork branch. It checks -# the complete PR file list for forbidden control or security-policy files. -# Optional text after `/claude fix` becomes steering; a bare command relies -# on the merge conflict or supported CI failure. A separate best-effort job -# acknowledges the command without making repair depend on a cosmetic API -# call. -# -# 2. Each attempt calls `_claude-fix-attempt.yml` from this trusted revision. -# That reusable workflow prepares a read-only Claude patch, validates and -# publishes it from a fresh runner, ensures CI exists for the exact SHA, and -# waits for the NVIDIA `pull-request/` CI run to finish. -# -# 3. Attempt 1 also tests an unchanged head when Claude has nothing to publish. -# A supported lint or non-GB200 unit-test failure enables the next attempt. -# Unsupported, stale, timed-out, green, and no-progress results stop early. -# Attempt 3 is the hard limit. -# -# 4. A session leaves at most one service-account commit in the PR branch -# history. The first change is an ordinary fast-forward push. A later attempt -# may amend only the exact bot commit returned by the preceding attempt, with -# an exact force-with-lease. Contributor history and concurrent branch -# updates cannot be replaced.

The acknowledgement job -# alone receives pull-request write access; it has no checkout or secrets and -# cannot block a repair. Claude never receives the service PAT or GitHub write -# access.

Get PR metadata: `gh pr view $PR_NUMBER --repo $REPO --json title,body,baseRefName,headRefName,files,additions,deletions,changedFiles,author` - 2. Get the full diff: `gh pr diff $PR_NUMBER --repo $REPO` - - For large PRs (>50 files), prioritize source code over config/lock/auto-generated files. - 3. For each significant changed file, read the full file for surrounding context. - 4. Trace data flow and dtype through computation paths to verify correctness. - 5. For each newly introduced variable/argument/field, verify it has a meaningful runtime use path (see Mandatory Check below). - 6. Post findings as inline comments with severity and category tags. - - ## Critical Issues (Must Fix) - - ### Implementation Correctness - - **dtype handling**: Verify operations use the correct dtype at each computation stage — explicit casts must be present at mixed-precision boundaries (e.g. fp16 compute → fp32 accumulation → fp16 output) - - **Loss scaling logic**: Verify DynamicLossScaler changes correctly detect inf/nan, adjust scale factor, and skip optimizer steps — incorrect logic causes training divergence or silent underflow - - **Reduction operations**: Verify reductions (sum, mean, allreduce) use correct dtype, reduction dimension, and normalization factor — wrong dimension or missing fp32 upcast produces silently wrong gradients - - **Normalization layers**: Verify LayerNorm/RMSNorm compute variance and mean on the correct dimension, with correct epsilon placement and upcast before rsqrt - - **Attention computation**: Verify QK^T scaling factor, softmax input dtype, causal mask application, and dropout placement match the intended algorithm - - **Residual connections**: Verify the correct tensor is added (pre-norm vs post-norm) with appropriate dtype for accumulation - - **Optimizer updates**: Verify state updates follow the correct formula — momentum/variance update order, bias correction, weight decay application - - **Gradient clipping**: Verify norm computation uses correct parameter set, norm type (L2 vs inf), and fp32 dtype - - **Embedding/output layer**: Verify weight tying is correctly wired, logit projection uses the right matrix, and output dtype matches expectation - - **MoE routing/aux loss**: Verify expert routing logic (top-k selection, capacity enforcement, token dropping) and auxiliary loss computation follow the intended algorithm - - ### Correctness - - **Tensor parallel**: Incorrect scatter/gather or allreduce placement — silent wrong results across TP ranks - - **Pipeline parallel**: Wrong microbatch scheduling, missing send/recv synchronization, incorrect grad accumulation across pipeline stages - - **Sequence parallel**: Incorrect sequence dimension partitioning or missing allgather/reduce-scatter in SP regions - - **Context parallel**: Incorrect KV cache partitioning or ring attention implementation errors - - **Expert parallel**: Token routing/dispatch errors across EP ranks, incorrect capacity factor handling - - **Gradient accumulation**: Missing no_sync() context or incorrect division factor when accumulating across microbatches - - **Checkpoint save/load**: State dict key mismatch, missing optimizer states, incorrect RNG state restoration — causes silent divergence after resume - - **RNG state management**: Incorrect random seed handling across TP/PP/DP ranks, causing correlated dropout masks or data sampling - - ## Important Issues (Should Fix) - - ### Training Performance - - **Unnecessary CPU-GPU sync**: .item(), .cpu(), torch.cuda.synchronize(), Python-side tensor value checks in training loop — kills throughput - - **Redundant communication**: Allreduce/allgather that could be fused, overlapped with compute, or eliminated - - **Memory inefficiency**: Missing activation checkpointing on memory-heavy layers, unnecessary tensor clones or .contiguous() calls - - **Communication-computation overlap**: Missed opportunities to overlap allreduce with backward, or allgather with forward - - **Kernel launch overhead**: Python loops over small ops that should be fused into a single kernel - - **CUDA graph compatibility**: Dynamic shapes, Python-side conditionals on tensor values, host-device sync inside captured region - - ### Backward Compatibility - - **Config/argument changes**: Renamed or removed arguments without deprecation path — breaks existing training scripts - - **Checkpoint format changes**: Modified state dict keys/structure without migration logic — makes existing checkpoints unloadable - - **Default value changes**: Changed defaults for training hyperparameters or parallelism settings — silently alters behavior for users relying on defaults - - **API contract changes**: Changed function signatures, return types, or side effects in megatron/core/ without backward-compat shim - - **Model architecture changes**: Altered layer ordering, initialization, or normalization placement — existing pretrained weights become incompatible - - ### Megatron Core Process Group Usage - - In `megatron/core` production code, treat new direct reads of global process groups - from `parallel_state` as review findings unless they are clearly compatibility-only. - - Flag added calls to `parallel_state.get_*_group()` or directly imported - `get_*_group()` helpers when the surrounding code could instead receive a - `ProcessGroupCollection` or explicit `torch.distributed.ProcessGroup` from its caller. - - Do not flag `megatron/core/parallel_state.py`, `megatron/core/process_groups_config.py`, - tests, docs, initialization/bootstrap code that materializes a `ProcessGroupCollection` - from MPU globals, or explicitly documented migration fallbacks. - - This guidance is advisory and targets Megatron Core library code; do not apply it to - `megatron/training` or other training-loop code unless the PR opts into that migration. - - ### Mandatory Check: Unused New Variables / Arguments - - For each changed file, list newly added identifiers (function args, config fields, locals). - - Verify each has a meaningful read/use path — not just declaration/docstring or discard assignment (_ = new_arg). - - Use Grep to search for usage beyond declaration sites. - - Treat placeholder discard patterns as findings unless explicitly documented as temporary migration shim. - - If usage is intentionally deferred, flag and request explicit TODO + migration note. - - ## Suggestions (Nice to Have) - - ### Naming - - Name must describe what the thing *is*, not what it's *used for* - - No abbreviations in parallel/distributed code — use full names (token_dispatcher, routing_map, comm_manager, world_size) - - Naming consistency within scope for variables serving the same role - - ### Function/Method Decomposition - - Functions over ~50 lines mixing data collection, reduction, computation, and I/O should be split - - Non-trivial logic blocks embedded in a method with different primary purpose should be extracted - - ### Simplification - - Redundant operations (e.g. .reshape(()) on 0-dim tensor, two-step constructions where one suffices) - - Setup constant across training should not run on every forward pass — move to __init__ - - Dead complexity that doesn't achieve its stated purpose - - Unnecessary intermediate aliases adding indirection with no abstraction value - - ### Other - - Stale, imprecise, or misleading comments/docstrings — a wrong docstring is worse than none - - Missing shape/dtype assertions at parallelism boundaries - - ## What NOT to Comment On - - Style/formatting issues (leave to linters) - - Test code that is reasonably clear - - Clearly intentional design decisions by the author - - Pure refactoring that preserves identical behavior (verify via diff) - - Findings invalidated by deeper analysis — drop them entirely rather than hedging - - ## Comment Format - - Prefix each comment with severity and category tag: - - `**[CRITICAL Implementation]**`, `**[CRITICAL Correctness]**` - - `**[IMPORTANT Performance]**`, `**[IMPORTANT Compatibility]**` - - `**[SUGGESTION Naming]**`, `**[SUGGESTION Simplification]**` - - For each finding, explain: (1) what the issue is, (2) why it matters (impact/risk), (3) specific suggestion for fix. - - Only use inline ```suggestion blocks for simple, self-contained line replacements (typos, - renames, single-line fixes). For structural changes that add, remove, or reorganize blocks - of code, use a top-level PR comment with a code block showing the proposed change instead. - - ## Completion - - After posting all inline comments, post a summary PR comment: - - List total findings by severity (CRITICAL: N, IMPORTANT: N, SUGGESTION: N) - - Highlight the most impactful findings - - Overall assessment of the PR's risk level - - If no significant issues are found, approve the PR: - gh pr review $PR_NUMBER --repo $REPO --approve --body "Strict review passed — no significant issues found.

Also read `.claude/skills/build-and-test/SKILL.md` - and `CLAUDE.md` for general CI and contribution guidelines. - - ## Hard Constraints - - **Exit condition:** You MUST run `gh pr ready ` before - exiting. That command is Phase 4. Do NOT exit after Phase 1, 2, - or 3 — not even if CI is "still running" or "stuck in queue." - Keep polling until it resolves, then act. - - **NO background tasks. Ever.** - You are running inside a single GitHub Actions step. The step - process owns your shell. When you stop issuing tool calls, the - step ends and the runner container is DESTROYED — every - background process dies with it and cannot resume. There is no - "future session" to wake up into. - - The following are strictly forbidden: - - `Bash` with `run_in_background: true` - - `Agent` with `run_in_background: true` - - `ScheduleWakeup` (nothing will ever wake up) - - Any shell command ending in `&`, or using `nohup`, `disown`, - or `setsid` to detach a process - - `tail -f` on a log produced by a backgrounded task - - Required shape for every long wait: ONE foreground Bash tool - call containing an inline `while true; do ... sleep ; done` - or `until ...; do sleep ; done` loop that BLOCKS inside - that single tool call and only returns when the wait is - resolved (success, failure, or a clearly-classified terminal - state). Do NOT break a long wait into many short polls with - conversation in between — that wastes `--max-turns` and - creates windows where the agent could forget the loop. - - **Pre-push guidance:** The workflow installs a local git pre-push - hook that reports CODEOWNERS, dependency-triple, and dev-feature - preservation findings. It is advisory and MUST NOT block a push. - Do not use `--no-verify`; let the hook run and review its output. - Restore genuine merge accidents and CODEOWNERS changes. For - intentional main removals or formatting/reordering false positives, - document the evidence in the PR body and continue. Do not stop or - ask for authorization solely because advisory findings remain. - - **Merge strategy:** Start from `origin/dev` and run - `git merge origin/main --no-edit`. Do NOT use global - `git merge -X theirs`. Main's version may be taken wholesale only - for files explicitly listed in the nightly-sync skill's - "Files to Override from Main" section. For other conflicts, - preserve recent dev-only additions and combine them with main's - incoming changes. - - **Source of truth for CI status:** - `gh pr view --repo $REPO --json statusCheckRollup` - This lists every required check — GitHub Actions jobs AND - external contexts (GitLab CI, `copy-pr-bot`, etc.). The - `gh api .../actions/runs//jobs` endpoint alone is - NOT sufficient — it misses external contexts. - - **Pre-existing failures:** MUST verify against recent dev CI - before classifying any failure as pre-existing. Run - `gh pr checks` on a recently merged dev PR. If the test passes - on dev, the failure is sync-caused and you must fix it. A - check that has never completed on your PR cannot be - pre-existing — wait for it to finish first. - - **Phase 4 gate — strict "all terminal, all green":** - Do NOT run `gh pr ready` until every non-exempt required check - in `statusCheckRollup` satisfies BOTH: - - `status == "COMPLETED"` (NOT `QUEUED`, `IN_PROGRESS`, - `PENDING`, `WAITING`, or `REQUESTED`), AND - - `conclusion` ∈ {`SUCCESS`, `SKIPPED`, `NEUTRAL`}. - A check stuck in a runner queue is NOT complete. Never - classify queued/in-progress jobs as "infrastructure-blocked" - and ship anyway — wait for them to reach a terminal - conclusion, then act on that result. When a check fails, - loop: diagnose → fix → commit → push → `/ok to test ` → - poll. Only exit the loop when the gate is satisfied on the - LATEST CI run against the current HEAD SHA. - - **Exempt checks (may be ignored for the Phase 4 gate):** - These categories are pre-merge policy signals, not - correctness signals, so their failure must not block the - sync bot from marking the PR ready for human review. - - - Approval / code-review: `codeowners-approval`, - `check-approval`, `multi-approval-bot-summary`, - `is-not-external-contributor`, any check whose name - contains `review` or `approval`. - - Code coverage: `Coverage (unit-test)`, `Coverage_Fake`, - any check whose name contains `codecov` or `coverage` - (case-insensitive). - - Docs: `build-docs / Build docs`, `build-docs-summary`, - any check whose name contains `build-docs`, `doc-build`, - `readthedocs`, or `sphinx`. - - Everything else — unit tests (`tests/unit_tests/...`), - integration tests (`gpt/...`, `moe/...`, etc.), `linting`, - `cicd-container-build`, `cicd-mbridge-testing`, - `Nemo_CICD_Test`, `copyright-check`, `pre-flight`, wheel - builds, etc. — is NOT exempt and must reach a terminal - green conclusion. - claude_args: | - --allowedTools "Bash,Read,Edit,Write,Grep,Glob,Agent" - --model "${{ vars.CLAUDE_MODEL }}" - --effort max - --max-turns 1500 diff --git a/.github/workflows/oncall-assign.yml b/.github/workflows/oncall-assign.yml deleted file mode 100644 index dc96f51b350..00000000000 --- a/.github/workflows/oncall-assign.yml +++ /dev/null @@ -1,47 +0,0 @@ -# Copyright (c) 2025, NVIDIA CORPORATION.

A repo may be a dependency, a consumer of +dependencies, or both, and each role is a mode of the same computation. + +A fork commit `D` of project P is compatible with a commit `N` of a project that pins P when: + + compatible(N, D) <=> base(D) == pin_P(base(N)) + base(X) = merge-base(X, upstream/) + pin_P(commit) = git ls-tree (in P's UPSTREAM consumer) + +`base` is computable from git, but only in a full clone with the upstream remote fetched. +Consumers commonly declare submodules `shallow = true`, so the dependency usually cannot be asked +— hence each fork records its own base in `.fork-base.json`, and `--check` re-derives it so the +record cannot drift silently. + +`--check` enforces four COMPATIBILITY rules: + + 1. `.fork-base.json` still matches `merge-base(HEAD, upstream/)`. + 2. Every pinned submodule is compatible: a patched dependency's recorded base equals the commit + upstream pins for it at our base; an unpatched one's gitlink equals upstream's exactly. + 3. A dependency's manifest describes the fork we actually pin (`fork_repo`) and the upstream we + actually expect (`upstream_repo`). Two forks can share an upstream base while carrying + entirely different patch sets, so the base alone does not identify a fork. + 4. A dependency's own nested submodules pin the same commits we do, matched by URL rather than + path (layouts differ between repos). The base rule alone cannot catch this: a patch may move + a nested gitlink without moving the dependency's base. + +Repos with no submodules simply have nothing to do for 2-4. + +It also enforces the SHAPE of history, which the compatibility rules assume but cannot see: + + 5. Our history and upstream's meet at exactly one commit. Several meeting points would make + `git merge-base` return an arbitrary one, so `upstream_base` would stop being reproducible. + 6. With `--against `, the base only ever moves forward. This needs both sides, so it is a + PR-level check. If the target ref carries no manifest yet — the bootstrap case, where this + very PR introduces it — that is reported as a note and does not fail. + +Merges from upstream are how the base advances: force-pushing is banned, so `git merge +upstream/` is the sync mechanism. It rewrites nothing — upstream's commits keep their SHAs +and simply become reachable, so merge-base moves forward on its own. + +The manifest deliberately records only fields that are stable across the patch series. Recording +the fork head or the patch SHAs would force a regeneration on every commit, and could never be +accurate inside the very commit that carries them. + +Usage: + tools/fork_base.py --write # regenerate .fork-base.json from git + tools/fork_base.py --check # verify the manifest AND the pins + tools/fork_base.py --check --json # machine-readable report + tools/fork_base.py --print # emit the computed base, for scripts + tools/fork_base.py --check --against origin/farai/main # PR: base must move forward +""" + +from __future__ import annotations + +import argparse +import configparser +import json +import re +import subprocess +import sys +from pathlib import Path + +MANIFEST = ".fork-base.json" +SCHEMA = 1 + +OK = "ok" +MISMATCH = "mismatch" +UNCHECKED = "unchecked" # could not verify — a failure unless --allow-skips +SKIPPED = "skipped" # structurally nothing to check — never a failure + + +def _git(*args: str, cwd: Path | None = None) -> str: + """Run a git command and return its stripped stdout.""" + out = subprocess.run( + ["git", *args], check=True, capture_output=True, text=True, cwd=cwd + ) + return out.stdout.strip() + + +def _git_ok(*args: str, cwd: Path | None = None) -> bool: + """Return True if a git command exits zero.""" + return subprocess.run(["git", *args], capture_output=True, cwd=cwd).returncode == 0 + + +def repo_root() -> Path: + """Return the repository root as a Path.""" + return Path(_git("rev-parse", "--show-toplevel")) + + +def current_branch(root: Path) -> str: + """Return the checked-out branch name, or "" when detached.""" + name = _git("rev-parse", "--abbrev-ref", "HEAD", cwd=root) + return "" if name == "HEAD" else name + + +def remote_url(remote: str) -> str: + """Return a remote's URL, normalized to https form without a trailing .git.""" + url = _git("remote", "get-url", remote) + if url.startswith( + "git@" + ): # git@github.com:org/repo.git -> https://github.com/org/repo + url = "https://" + url[4:].replace(":", "/", 1) + return url.removesuffix(".git") + + +def normalize(url: str) -> str: + """Normalize a URL for comparison: https form, no .git suffix, lowercased.""" + if url.startswith("git@"): + url = "https://" + url[4:].replace(":", "/", 1) + return url.removesuffix(".git").rstrip("/").lower() + + +def compute_base(upstream_remote: str, upstream_branch: str, rev: str = "HEAD") -> str: + """Return the commit this fork is rebased onto: merge-base(rev, /).""" + ref = f"{upstream_remote}/{upstream_branch}" + if not _git_ok("rev-parse", "--verify", ref): + sys.exit( + f"ERROR: {ref} not found.
