+title: "The changelog gate stamps an untagged version with the current date, so its verdict flips every midnight with no commit"
+description: "pm-changelog synthesises a pending release window for a version that has no matching git tag and stamps it with the current UTC date rather than anything derived from the input. The release workflow tags only after npm publish succeeds, and publish has been failing fleet wide since 2026-08-21, so this package currently carries an untagged version and is on that clock dependent path. The exposure is masked today only by a coincidence, because the package version and today's date are the same calendar day, and it fails on any later day with no commit having changed. Verified on pm-ops where the version date and today's date differ, which makes the comparison decisive: an untagged 2026.8.22 generates heading 2026.8.22 - 2026-08-24 without the flag and 2026.8.22 - 2026-08-22 with it. The remedy needs no new code because pm-changelog 2026.8.17 already ships --date-from-version, and zero of twenty packages passed it. Applied to every invocation of the generator in this package rather than only to the scripts whose names begin with changelog, because the release workflow invokes it directly and generation and check must not disagree. Site audit: package.json sites 1 flagged 1; .github/workflows/release.yml sites 2 flagged 2;"

+  "2026-08-24T10:03:10.966Z","harness:claude-code","CodeRabbit was right that the linked test only covered the package.json invocation and never reached the direct pm-changelog commands in the release workflow. Added an executable check that does both halves. The static half enumerates every tracked file containing a generator invocation and asserts each file's flagged count is not below its site count, which fails when any single site loses the flag; verified by removing the flag from one of two release.yml sites and watching it report one of two and exit non-zero. The behavioural half runs the generator twice on the same probe version 2026.1.2, deliberately chosen so its calendar date cannot coincide with today, and asserts the heading is 2026.1.2 - 2026-01-02 with the flag and 2026.1.2 - 2026-08-24 without it, so the test states the defect rather than merely asserting the fix."
+  "2026-08-27T17:18:36.511Z",claude-agent,"The verifier this issue added was a file the repository shipped and nothing executed. It was absent from release:check and from every CI step, in thirteen of the fifteen repositories that carry it, so a later edit could have removed --date-from-version from the workflow and both generation and --check would have agreed on a clock-derived date without anything failing. It is now a named script, the last step of release:check, and its own CI step. Reported by CodeRabbit on unbraind/pm-graph#70.\n\nThe verifier itself gained two fixes in the same pass, also from CodeRabbit. Its static section now balances flags per line rather than per file, which closes two hiding places at once: a single line carrying several invocations where only one is flagged, and an unflagged invocation hiding behind a mention of the flag on a line that invokes nothing. Its behavioural section no longer runs the unflagged control under || true, so a control that fails to produce a heading now fails the gate instead of printing a note while the script exits zero. Both were confirmed by executing the old script against the defect and watching it exit zero."
