fix: compare each policy's full read, not its list entry - #229
Conversation
The second run of the apply workflow reported UPDATED for all ten policies although no file had changed. GitHub's list endpoint returns each policy in a form that does not match the single-policy read, and the reconciler compared against the list entry, so every run rewrote every policy and real drift would hide among routine updates. A policy found by name is now read in full before it is compared, a failed read is FAILED with nothing written, and UPDATED and DRIFT print what the live policy was. The API stand-in's list returns summaries, so the tests fail if the comparison reads the list entry again. Fixes #228 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe apply script now reads and validates every managed policy in full before it writes any policy. It compares normalized content from those full reads and reports live policy content for drift and successful writes. The test harness returns summary-form list entries, simulates full-read failures and malformed responses, and checks that the script makes no writes after a failed read. The README test description now includes the full-read comparison condition. Merge Risk: 🟡 Moderate · up to Malformed policy responses can cause an unintended create request or leave only some policies updated. Handle both cases before merging so an uncertain read cannot trigger writes. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Reading each policy just before comparing it meant a failed read of a later policy came after earlier policies had already been rewritten, and a read that succeeded but returned something other than the policy counted as drift and triggered a write. Both break the promise that nothing is written unless every live policy was read. Every managed policy is now read in full and shape-checked first. One that cannot be read, or is not the policy asked for, is UNKNOWN and the run writes nothing. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

validate that `.conditions` is an object and run the `normalize` jq filter on
each policy before saving it or allowing any writes. If validation or
normalization fails, report the policy as UNKNOWN and ensure the workflow writes
nothing.
- Line 164: Update the live-policy lookup in the apply loop to distinguish no
matching entry from a matching entry without an id: continue to the POST
creation path only when no entry matches, and report UNKNOWN without writing
when a matching entry lacks an id. Preserve full-read validation for entries
with an id.

A listed policy without an id looked like a missing one, so the run would create a duplicate. A full read whose conditions the comparison cannot handle passed the shape check and failed only in the write pass, after earlier policies had been rewritten. Every listed policy must now carry a numeric id and a name, and each full read is normalized in the read pass. Either failure is UNKNOWN with nothing written.

Why
After #227, the apply workflow's second run rewrote all ten policies although nothing had changed. It compared each file with GitHub's policy list, which describes policies differently from a single-policy read, so every run looked like drift. Real drift would hide among those routine updates.
What
Each policy is now compared with its own full read, so an unchanged policy is left alone and only a real difference triggers an update. When a policy is updated or drifts, the run log now shows what it was.
Fixes #228
👉 After merge: I start the workflow once more and confirm every policy reports in sync with nothing written.
