- In
theseus.config.json(repozedmilestone at date2023-12), update the date to2024-01: Zed was open-sourced on 2024-01-24, and the GPUI2 transition hit the preview channel in early Jan 2024.- The current milestone title (“GPUI2 Transition and Open Sourced”) combines two distinct events; splitting it into separate milestones for GPUI2 transition vs open-source release improves clarity.

Inline comments:
In `@data/langchain_data.json`:
- Line 1: The snapshots in data/langchain_data.json include future-year "2026"
keys that violate the cleanup logic; fix by running or re-running the existing
cleanup that uses max_year = int(snapshot_date[:4]) and deletes composition keys
with int(year) > max_year (the del composition[key] step in
scripts/cleanup_data.py), or adjust your data generation to never emit
future-year entries (remove/justify all "2026" composition keys across snapshots
such as the 2023-06 and 2025-12 entries) so the file is consistent with the
Filter future years rule.
In `@data/react_data.json`:
- Line 1: The snapshot 2013-12 in react_data.json contains a future-year entry
("2014":6) that should have been removed by the cleanup logic; update the
cleanup logic in cleanup_data.py (the filtering block around lines 38-45) or
re-run the cleanup to ensure snapshot compositions drop any year > snapshot year
(e.g. remove the "2014" key from snapshot_date "2013-12"); specifically, ensure
the function that processes snapshots enforces year <= snapshot_year for each
composition entry and write the cleaned output back to data/react_data.json,
then re-run the pipeline verification.
In `@data/zed_data.json`:
- Line 1: The zed_data.json snapshots before 2026 incorrectly include a "2026"
composition key, so trace the code that builds snapshot compositions (functions
like mapTimestampToYear / buildComposition / generateSnapshots or whatever
computes composition years from fossil.timestamp or git blame timestamps) and
confirm whether it uses commit/timestamp time (possibly with clock skew/UTC
conversion) instead of the snapshot_date year; fix by either using the
snapshot_date's year as the authoritative bucket or clamping computed years so
they are <= snapshot_date year (or otherwise deriving year from the
snapshot_date string), and add a unit/CI check to reject future-year keys for
past snapshot_date entries.
In `@scripts/_utils.py`:
- Around line 147-171: The code references stat.S_IWUSR, stat.S_IWGRP, and
stat.S_IWOTH inside the handle_remove_readonly callback used by shutil.rmtree
but the stat module is not imported, causing a NameError; fix by adding an
import for the stat module (import stat) near the top-level imports so
handle_remove_readonly (and its use in
shutil.rmtree(onexc=handle_remove_readonly)) can access stat constants.
- Around line 148-166: The retry loop currently calls shutil.rmtree(path,
ignore_errors=False) before the onerror handler is defined so the handler is
never used; move the handle_remove_readonly definition above the first
shutil.rmtree call and invoke shutil.rmtree(path,
onerror=handle_remove_readonly) inside the loop (dropping the duplicated rmtree
call) so each retry uses the handler to fix permissions and retry deletion;
reference the existing shutil.rmtree and handle_remove_readonly names and the
for attempt in range(3) loop when making the change.
In `@theseus.config.json`:
- Line 44: Update the React 19 milestone date in theseus.config.json by changing
the "date" field for the React 19 milestone entry from "2024-06" (or "2024-04")
to "2024-12"; locate the React 19 milestone object (the entry containing the
"date" property shown in the diff) and set its "date" value to "2024-12" to
reflect the stable release on 2024-12-05.

integer—reference update_survivor_fossils, had_failures, and updated_count when
making the fix.

In `@scripts/_data_io.py`:
- Around line 65-73: The JSON loader currently returns raw dicts or other JSON
values, which can lack the expected "snapshots" (list) and "fossils" (dict) keys
and cause KeyError in backfill_fossils and update_survivor_fossils; after
json.load(...) in the existing try block, normalize the result so you always
return a dict with "snapshots" (ensure it's a list, otherwise set to []) and
"fossils" (ensure it's a dict, otherwise set to {}), and if the JSON is neither
a list nor dict, return {"snapshots": [], "fossils": {}}; update the branch that
currently returns data to perform this normalization before returning.
In `@scripts/add_fossils.py`:
- Around line 305-309: The code directly indexes data["snapshots"] after calling
load_snapshot_data which can raise KeyError for malformed JSON; update the
load_snapshot_data implementation to normalize its return value so it always
includes both keys (at least "snapshots" as an empty list and the other expected
key(s) as sensible defaults) and ensure callers (e.g., where load_snapshot_data
is used) can safely index "snapshots" without a try/except; keep the call site
(load_snapshot_data(...)) unchanged and instead make load_snapshot_data return a
dict that always contains "snapshots" to prevent uncaught KeyError.
