feat(rulesets): base protection floor applier, branch + tag - #1034
Conversation
Closes the last structural gap in "modern rulesets only": every repo in both
estates reaches a base-level protection, expressed purely as a ruleset. No
classic branch protection is created, read or migrated -- it is already gone
estate-wide (measured 0 of 283; the classic TAG endpoint is retired and 404s).
The floor is deletion + non_fast_forward, zero bypass actors, on
~DEFAULT_BRANCH for branches and ~ALL for tags.
Three siblings now exist and do not overlap:
apply-branch-gates.sh fills required_status_checks on an EXISTING ruleset
apply-tag-ruleset-canon.sh reconciles the tag canon
apply-protection-floor.sh CREATES a floor where no ruleset exists at all
The gap this fills is named in config/rulesets/README.adoc: the gate-filler
never creates a ruleset, because creating protection where none exists is a
policy act rather than a gate-fill. That is now a separate, explicit script.
D50 is enforced structurally, not incidentally. git-remote-gcrypt force-pushes
by design on every sync, so writing non_fast_forward to a gcrypt vault does not
harden it -- it silently stops the hourly backup at the next timer fire. The
two members are an EXPLICIT LIST in config/rulesets/gcrypt-vault-class.txt,
never a name regex: reasonably-good-token-vault and befunge93-vault-cracker
both match /vault/ and both genuinely need the floor. A missing class file is a
REFUSAL, because an absent exclusion list is indistinguishable from an empty one.
Safety properties, each covered by an assertion:
- APPLY=0 by default; writes require --apply
- the D50 check runs BEFORE any API read, so a vault is never even probed
- shape identity includes bypass_actors, so a bypassed twin is not "converged"
- an absent .source_type REFUSES rather than defaulting to the writable arm
(PUT to an org-inherited ruleset 404s; the discriminator is the only guard)
- 403/422 on the rulesets list is PLAN-EXCLUDED, establishing the private
denominator structurally instead of guessing it
- every write is verified by an INDEPENDENT re-read: a ruleset PUT has
returned 200 with an empty body and not applied
- an empty repo list is refused, so a clean sweep is never reported over nothing
The suite kills four mutants. Two of them only became honest after the harness
itself was fixed: the mutant had been written to a temp dir, so REPO_ROOT
resolved there and it died on a missing canon file before any guard ran, which
bash -n cannot catch. The mutant now lives in the real scripts/ dir, the sed is
asserted to have changed something, and a mutant that produces no report is
treated as a meaningless red rather than a kill.

Suggested reviewers: Merge Risk: 🟡 Moderate · up to The new protection-floor script can mislabel which repositories need protection. It can skip repositories whose default branch is unprotected, mark rate-limited repositories as plan-excluded, create redundant per-repo rulesets where organisation rules already apply, and report success for a write that did not take effect. A name-format mismatch could also apply a force-push block to a gcrypt vault and stop its backups. Fix these before running 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@scripts/apply-protection-floor.sh`:
- Around line 155-157: Update the error classification in the `case "$err"`
block so rate-limit and abuse messages are matched first and reported as
UNKNOWN; only classify remaining 403, 422, or upgrade errors as PLAN-EXCLUDED.
Keep the existing fallback behavior for other errors.
- Around line 182-186: Update the ruleset evaluation so `union` includes rule
types only when the ruleset’s `conditions.ref_name.include` contains the wanted
floor target and its exclusions are empty. Update the exact-match check to also
reject rulesets with exclusions, while preserving its existing type, include,
and bypass checks. Keep bypass actors excluded from coverage only if that
matches the intended policy.
- Around line 169-170: Track active organization ruleset IDs separately from
repository IDs in the ruleset listing, then fetch and inspect them alongside
repository rulesets while accumulating their in-scope types in a separate
org_union. Add a coverage check for every FLOOR_TYPES entry and use it before
the per-repository creation path to report ORG-INHERITED only when organization
rulesets actually provide the floor; keep organization coverage separate from
repository coverage.
- Around line 245-248: Update the effective-rule verification in the floor-write
flow to require each requested type to have a matching ruleset_id for new_id,
rather than accepting rules supplied by any ruleset. If new_id is empty, report
the write as unverified and stop that verification path; update the
rules_branches_main fixtures to include the corresponding ruleset_id values.
- Around line 121-129: Normalize entries in VAULTS and TARGETS to remove
carriage returns, and make is_vault compare names case-insensitively. After
metadata is read in the repository-processing flow, check its canonical
full_name with is_vault and report and skip any repository that matches.
In `@scripts/tests/protection-floor-test.sh`:
- Around line 188-193: Change the mutant setup in the protection-floor test to
write under the per-run `$WORK` directory instead of the checkout’s `scripts/`
directory. Create the temporary `scripts` and `config/rulesets` tree, copy the
canonical ruleset files there so `apply-protection-floor.sh` can resolve them,
and update the cleanup trap to remove the temporary tree.
- Around line 136-143: Extend the protection-floor test fixtures created with
mkrepo to cover organization-only inheritance with no POST, a rate-limited 403
yielding UNKNOWN, a release/* ruleset containing both rules yielding
WOULD-CREATE, and an apply case with an empty POST response and effective rules
from an older ruleset yielding WROTE-UNVERIFIED.

ORG-INHERITED was unreachable dead code. `org_n` counted active org-level rulesets of the target, but their rule types never entered `union`, which was built only from repo-level rulesets. Since the ORG-INHERITED branch required `covered == 1`, it could never be taken. Measured impact: after creating the zero-bypass org `Branch-Floor` on metadatastician (`~ALL`, verified live by an independent re-GET), a report-only run still returned 67 WOULD-CREATE. Under `--apply` that is 67 duplicate per-repo rulesets for a rule already in force org-wide. Fix: org rulesets of the target are read (cached by ruleset id, since the body is identical across every repo in the org) into their own `union_org`. Cover is then evaluated twice -- repo-level first, so a curable cover still reports COVERED-BY-RICHER, then org-level for ORG-INHERITED. The detail line now also carries the covering org rulesets' maximum `bypass_actors` count, because a cover that many actors can bypass is weaker than its rule list suggests. Tests: two new fixtures and one new mutant. - a COMPLETE org cover must report ORG-INHERITED and receive no duplicate POST - a HALF org cover (the real EstateBranching shape: `deletion`, no `non_fast_forward`) must still be WOULD-CREATE -- a half cover is not a cover - mutant `org cover dropped from the union` reproduces the shipped bug exactly and now POSTs a duplicate, so it dies The org-covered fixture is deliberately writable so the mutant produces a real duplicate POST rather than dying on a missing fixture -- the false-green trap this suite has already been bitten by twice. 34 passed, 0 failed; 5 mutants, all dead.

The "Nothing here is applied automatically" section predated both appliers and told readers the propagation mechanism did not exist. It now names apply-branch-gates.sh and apply-protection-floor.sh, and records the four findings a future reader needs before touching a floor: - a floor read without bypass_actors is not a floor (EstateTagging carries every floor rule and three actors that bypass it always) - org cover is a distinct state from repo cover, discriminated by .source_type; an absent .source_type is a refusal, not a default to the writable arm - a half cover is not a cover (EstateBranching: deletion, no non_fast_forward) - the gcrypt vault class must be excluded by explicit list, never a name regex Also documents why the floor canon is branch-floor.json / tag-floor.json rather than base*.json: base.json is the richer tier and the collision would mislead. Refs #787 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Ji1bq3TypfycfUPAR7hSxR
GitHub answers a primary rate limit, a secondary limit and an abuse trip with 403 -- the same status a private repo on a plan without rulesets returns. The discriminator matched `*403*` first, so a throttled read was recorded as "private repo / plan limit" and the protection gap was silently under-reported. Caught live: the estate sweep was stopped with quota at 598 and 163 repos left, before a single row could be misfiled. is_throttled() now classifies on the lowercased body (rate limit, rate-limit, abuse detection, retry-after, http 429) ahead of the plan arm, and reports UNKNOWN -- a throttled read is skipped, never recorded. Two fixtures pin it (primary and secondary limit), the existing private-repo 403 stays as the negative control proving the throttle arm did not swallow the plan arm, and a mutant silencing the guard flips throttled-repo back to PLAN-EXCLUDED. 37 passed, 0 failed, 6 mutants dead.

A throttle is a property of the CREDENTIAL, not of the repo: once the hourly window is spent, every remaining repo fails identically. Measured twice today -- a 267-repo apply ran straight through the wall and filed 111 repos as UNKNOWN, and a second run filed 93 more before it was stopped. UNKNOWN is the honest state for one throttled read, but 111 of them read as "measured and unknowable" when they mean "never looked". note_throttled() counts CONSECUTIVE throttled reads and aborts the sweep at three with an ABORTED row naming the cure. A single secondary-limit blip is tolerated: any read that gets through clears the count. The counter is wired into all three places the wall actually shows -- the first repo read, the rulesets list, and (on --apply) the POST. A dedicated target list drives the new section: three repos named to sort FIRST, then plain-repo, which must never be reached. A mutant that neuters the abort reaches it and writes to it. 41 passed, 0 failed, 7 mutants dead.

The backoff added in 34a5404 could not fire on the wall it was written for. `throttled=0` sat immediately after the repo metadata GET, but at the quota wall a repo's GETs still succeed and only the POST is refused: 87 of the 111 UNKNOWN rows in the 2026-09-23 sweep are `POST failed`, against 23 whose metadata read died. Under the old placement that sequence is GET ok -> reset -> POST throttled -> 1 -> GET ok -> reset, so the counter never reaches the limit and the 267-row grind repeats. The streak now counts consecutive REPOS. `note_throttled` marks the current repo, and the reset at the top of the loop body fires only when the previous repo completed without a throttle, so a single blip is still tolerated. The existing fixtures throttled on the metadata read, which sits before the reset, so they were blind to this shape. Adds a POST-throttle triple with healthy GET fixtures, `.rc` handling in the shim's non-GET branch (it had none), and a mutant that silences repo_throttled -- the defect verbatim -- which dies on the repo beyond the wall being reached.

In `@scripts/apply-protection-floor.sh`:
- Around line 276-279: Update the org-ruleset fetch in the ruleset cache loop so
`$cache` is written only after `gh api` succeeds and its response contains a
`.rules` array; on failure, leave the cache empty, and preserve throttling
detection through `is_throttled` and `note_throttled`. In the report guarded by
`org_read_ok`, skip the second row when `repo_throttled` is set so a throttled
repository is reported only once.
- Around line 280-282: Update the org-ruleset walk that builds union_org to
include rule types only when the ruleset’s ref_name include scope contains
WANT_INCLUDE and its exclude scope is empty, matching the repo-level coverage
check. Add a fixture for an org ruleset covering only refs/heads/release/* with
both required rule types, and verify the expected state is WOULD-CREATE.

340-343: 🎯 Functional Correctness | ⚡ Quick winThe write check still does not prove that the POST took effect.
The check at Line 342 accepts a rule of each floor type from any ruleset. It does not match
ruleset_idagainstnew_id. It also accepts an emptynew_id. With--floor-even-if-covered, the richer ruleset already supplies both types. So a POST that returns 200 but does not apply is still reportedCREATED. The earlier comment is marked as addressed. The code and therules_branches_mainfixtures still have neither change.
127-127: 🩺 Stability & Availability | ⚡ Quick winThe D50 vault check can still miss a vault, which then gets written.
Line 127 removes only spaces and tabs.
is_vaultcompares names exactly and is case-sensitive (grep -qxF). The check therefore misses a vault in three cases:
- One of the input files has CRLF line endings.
- The repo list uses different letter case. GitHub treats owner and repo names as case-insensitive.
- A vault was renamed. The check does not re-test the canonical
.full_nameafter the metadata read.In each case the script POSTs
non_fast_forwardto the vault. The earlier comment is marked as addressed, but the code has not changed.Also applies to: 165-167

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Org rulesets count as cover without checking which branches or tags they apply to.
The repo-level walk at Lines 242-245 adds a ruleset's rule types to union only when two conditions hold:
conditions.ref_name.includecontains$WANT_INCLUDE.excludeis empty.
The org walk at Line 280 adds every org ruleset's types to union_org without that check. For example, an org ruleset with deletion and non_fast_forward on refs/heads/release/* makes covered_org=1. The repo is then reported ORG-INHERITED, and no floor is written. The default branch stays without the floor. This is the defect that was fixed earlier for repo-level rulesets. Here it hides a real gap, which is the unsafe direction.
Apply the same scope check to org rulesets. Add a fixture: an org ruleset with both rules on refs/heads/release/*, expected state WOULD-CREATE.

What this is
The third sibling in
scripts/, and the one the repo's own docs said was missing.apply-branch-gates.shrequired_status_checkson an existing rulesetapply-tag-ruleset-canon.shapply-protection-floor.sh← newconfig/rulesets/README.adocnames the gap directly: the gate-filler never creates aruleset, because creating protection where none exists is a policy act, not a
gate-fill. This PR makes that policy act a separate, explicit, owner-ruled script.
The floor
deletion+non_fast_forward, zero bypass actors — on~DEFAULT_BRANCHforbranches (
config/rulesets/branch-floor.json) and~ALLfor tags(
config/rulesets/tag-floor.json). Deliberately not namedbase*.json:base.jsonis the richer tier and the collision would mislead every future reader.
Modern rulesets only. Nothing here creates, reads or migrates classic branch
protection. It does not need to: classic protection is already gone estate-wide
(measured 0 of 283 repos with a two-way-proven detector), and the classic tag
protection endpoint is retired — it 404s even under full admin, returning the
generic docs root, which is the tell.
The trap this had to be built around
git-remote-gcryptforce-pushes by design on every sync. The remote ref is a rollingpointer at the newest encrypted pack and is never a fast-forward. So the naive floor
logic — "has
deletion, lacksnon_fast_forward⇒ complete the floor" — writes exactlythe rule that silently stops the hourly backup at the next timer fire. Both gcrypt
vaults sit in that bucket.
Enforcement is therefore structural, not incidental:
config/rulesets/gcrypt-vault-class.txt), never aname regex —
reasonably-good-token-vaultandbefunge93-vault-crackerboth match/vault/and both genuinely need the floor; a name match is wrong in both directionsindistinguishable from an empty one
Ruling: D50.
Safety properties, each with an assertion behind it
APPLY=0by default; writes require--apply, never the inversebypass_actors— a bypassed twin is not "converged".source_typeREFUSES rather than defaulting to the writable arm. APUTto an org-inherited ruleset 404s (measured 67×); the discriminator is the only guard

PUThas returned200with an empty body and not appliedCOVERED-BY-RICHERis reported as its own state, not as converged — a floor livinginside a richer ruleset vanishes the moment that ruleset is disabled, which is exactly
what produced the 230-repo hole
There is no
evaluate/dry-run mode on this plan (422: "not supported on this plan"),so the rollout is canary-one-then-widen, not "evaluate first".
Tests: four mutants, and an honest harness
scripts/tests/protection-floor-test.sh— 27 assertions, 4 mutants, all dead for theright reason.
⚠ The first green run of this suite was worthless and I am recording why. The mutant
was written to a temp dir, so
REPO_ROOTresolved there and every mutant died onFATAL: canon file missing: /tmp/config/rulesets/branch-floor.json— before any guardran.
bash -npasses on such a mutant, so the standing "syntactically-invalid mutant"pre-check does not catch it. All four "deaths" were crashes.
Cured by three changes, now permanent properties of the harness:
scripts/dircmp -sasserts the sed actually changed something (a no-op sed is a fake kill)Two mutants then legitimately survived, and both were right to:
archived guard removed—archived-repohad no fixtures, so the mutant died on amissing fixture rather than writing. Fixed by making it fully writable in mutant mode,
so guard removal now produces a real POST. Two baseline assertions added: archived
stays
ARCHIVEDand receives no POST even when writable.converged early-return removed— this one is caught by a second line of defence(it falls through to
COVERED-BY-RICHER, not to a write). So it is asserted on thestate it corrupts, not on a POST that correctly never happens.

That
asymmetry is the standing argument for D97.
⚠ Correction — an earlier revision of this PR said "one field on
EstateBranching"That was wrong and unsafe, and it is corrected above. Full detail in
#787comment 5791525698.In short:
EstateBranchingcarries 9 bypass actors (4 atmode=always) andEstateTagging3, all atmode=always, so appending a field to either would haveshipped a floor those actors walk straight through — against the owner's Q3 ruling,
"no bypass at all" — and Q2 ruled the base floor is added alongside, not by editing
a richer ruleset. A floor that lives inside a richer ruleset also dies the day that ruleset
is disabled, which is what happened to 375 rulesets on 2026-09-22.
A ruleset's rules say what it forbids;
bypass_actorssays whom it forbids it to. A floorread without the second column is not a floor.
That correction exposed a real defect in this PR's own applier
