…nd to an agent (BE-16052)
A model upload is one streamed PUT that can run for an hour, and until it
ends `comfy build push` printed nothing. Neither a person nor an agent
driving the CLI could tell a slow upload from a dead one.
Push now prints the plan before the first byte ("3 files, 53.0 GB to
upload, 2 already held"), and says so even when there is nothing to send.
While a file moves it reports bytes sent, rate and time left:
- at a terminal, one redrawn Rich progress line per file;
- with pretty output piped, a plain line every five seconds, no carriage
returns;
- under --json-stream, upload_plan / upload_progress / upload_complete
events on stdout;
- under --json, the same event/1 lines on stderr, so stdout stays the
single envelope. A caller with a piped stdout resolves to this mode, so
this is what an agent sees.
upload_blob wraps the file in a reader that counts each block the transport
pulls. It passes fileno, mode and tell through, so requests sizes the body
exactly as it sizes the bare file: same Content-Length, no chunked transfer,
same headers and timeout.
The numbers are sampled by a one-second ticker, not by the byte callback,
and the rate is measured over a ten-second sliding window. A stalled socket
stops the callback, so a reporter driven by it would go quiet exactly when
the reader needs to see the rate fall to zero.
A progress write the stream refuses turns reporting off for the rest of the
push instead of failing the upload.
The deploy-progress work (BE-16056) needs the same size and duration wording and the same surface choice, and had copied both. A person meets the two waits in the same terminal minutes apart, so they cannot be allowed to drift. comfy_cli/output/progress.py now owns human_bytes, human_seconds, the Surface alias and surface_for(); the upload reporter imports them. It sits in output/ because it belongs to neither command, and putting it beside one would make the other import a module named for a command it has nothing to do with. Also widens the build schema orphan sweep to read both catalogs. build push is the first build command with an event stream, so its schema is registered in STREAM_EVENT_SCHEMAS, and a sweep reading only COMMAND_SCHEMAS reported a live schema as abandoned. test_discovery.py already pairs the two for this reason.

test_the_ticker_thread_reports_without_being_driven to control the ticker and
event intervals with short monkeypatched values, then wait until ticker output
appears before leaving reporter.uploading. Assert that at least two
upload_progress events were emitted, upload_complete is last, and no
comfy-upload-progress thread remains, avoiding a timing-dependent exact sequence
assertion.

Reviewed streamed request sizing, upload callbacks, ticker lifecycle, progress output modes, and schema integration. No blocking findings. All 99 targeted upload/reporter/transport tests pass locally on Python 3.10.
The GPU CI job remains red: its log shows the two uv-compile conflict-message tests failing, the same failures across these four PRs in code outside these changes. Other reported checks pass. I did not rerun GPU E2E or live analytics/provider operations.
…ead of failing the push (BE-16052) Rich's Progress.add_task redraws the display, so it is a second place the terminal can refuse a write, after start. Only start was inside the OSError boundary; an add_task failure escaped _open_live and failed the upload it was only meant to narrate. Both calls now share one boundary, a half-opened display is stopped, and nothing is published until both have landed. The ticker test drove nothing: it left the block before the one-second tick and asserted an exact sequence that a slow scheduler could lengthen. It now shortens the tick, waits for the ticker to report on its own, and checks the thread is gone.
…-16052) The type field said to ignore unrecognised types and then closed the list with an enum, so a schema-validating reader would reject the additive event a newer CLI adds. The enum is gone; the per-type required fields stay.

Self-review of the fix push, head e8f9310 (e8dd6fe, 61dc359, e8f9310), read cold against d3ae073 together with Rich's Progress.add_task / refresh and Live.start.
Findings
tests/comfy_cli/command/test_build_upload_progress.py, the ticker test as first written: the wait loop parsed the NDJSON stream from the main thread while the ticker thread was still writing it, so a read landing between two writes could hit a half-written line and fail on the parse, not on the behaviour. Fixed in e8f9310: the wait counts newlines and the parse happens after the thread is joined.- Same file,
_LiveRenderer.inforaised: the refused-display test passed only because the reporter was muted before the completion line, and that was the thing under test, so the assertion was implicit. Fixed in e8f9310:inforecords what it is told and the test asserts nothing was said. comfy_cli/command/build_upload_progress.py_open_live:live.stop()also runs whenstart()itself raised. Checked:Live.start(refresh=True)stops itself when its refresh raises, andstopon a Live that never started returns early, so the second stop is a no-op. Left.comfy_cli/schemas/run_event.jsonkeeps an enum under the same "advisory, open-ended" wording, the contradiction this push removes frombuild_push_event.json. That is thecomfy runcontract, out of this PR's scope; noted for a separate change.
Checked: each new test fails with its fix reverted (the OSError escapes _open_live; the enum rejects the unknown type). Full suite on e8f9310: 7896 passed, 38 skipped, 2 failed, and the two are test_node_deps::test_non_pep440_installed_version_is_unknown_not_a_crash and test_http::test_an_unloadable_supplement_falls_through_to_the_platform_roots, which fail on main and touch no file in this branch.

Approving. Reads as: build push prints a plan, then bytes, rate and time left per file, as a redrawn line, plain lines or events on stderr under --json. Head e8f9310, judged as comfy-cli's owner.
Optional
- Resilience: a push whose caller never drains stderr hangs after the upload finishes
comfy_cli/command/build_upload_progress.py:179. The ticker blocks writing under the lock once the pipe fills, and the join has no timeout. - Correctness: the time left beside a file is the whole push's
comfy_cli/command/build_upload_progress.py:360. File 1 of 3 showed 24m 56s left with about 8m to go on it. - Correctness: piped output wraps one sample over two lines
comfy_cli/command/build_upload_progress.py:286. The piped console is 80 columns, so a long filename pushes the time left onto its own line. - Correctness: piped output still gets redraws when a color variable is set
comfy_cli/output/progress.py:68. Rich reports a terminal under FORCE_COLOR, which breaks the ticket's no-redraw criterion. - Modularity: one line mixes GiB and MB/s for the same 1024-based bytes
comfy_cli/command/build_upload_progress.py:302. Render the byte counts with the shared formatter. - Verbosity: the no-reporter path runs only in tests
comfy_cli/command/build_push.py:309. The one production caller always passes a reporter, so make it required. - Scope: the diff is 1,490 lines, past the 400-line ceiling
comfy_cli/output/progress.py:1. Next time land the shared wording module on its own ahead of the reporter.
Clean: Access, Tests, Reachability, Contract, Rollout.
Native review: 10 findings, folded into the list above.
Checked: A scratch push whose parent read only stdout hung after its upload ended. Piped runs showed the redraws and the split line.
Bots: The ticker test fix holds at this head: it fails once the ticker is disabled.

Description
TL;DR:
comfy build pushsays how far along a model upload is. Today it prints nothing between starting a multi-GB upload and finishing it.Why: a private model is routinely many GB, and the command is silent for the whole transfer, to a person and to an agent alike. Part of BE-15748.
Before / After
upload_plan/upload_progress/upload_completeevents for an agent under--json-stream. Under plain--jsonthe events go to stderr, because stdout there is contractually one envelope.file_utils.py:356: description, bar, numbers,transient=True).comfy_cli/output/progress.pyis new and shared:Surface,human_bytes,human_seconds,surface_for(renderer). The deploy watch in BE-16056 words its wait with the same functions, so the two cannot drift. Sizes count in 1024s because the portal'sformatBytesdoes.comfy_cli/schemas/build_push_event.json, registered inSTREAM_EVENT_SCHEMAS. The build schema orphan sweep read onlyCOMMAND_SCHEMASand reported it as abandoned; it now reads both, astest_discovery.pyalready does.Closes BE-16052.

That run was on Python 3.12 and CI targets 3.10, which is the likely cause.ruff checkandruff format --diffclean. 13 new tests intests/comfy_cli/output/test_progress.py.Manually: real uploads of 722,601,100 and 7,272,719,498 bytes, at a terminal and piped (313 bytes, 5 lines, 0 escape codes when captured). Two clean-room runs gave an agent only the command and asked it to narrate the upload; it reported progress and the finish correctly from the plain lines as well as from the events.
