A refused read now names a copy the being can already read, as an alternative. request_scope still files the ask, and adds the copy to its result.

Revised at f3fe81a after Nova's HOLD on 78efe4a. request_scope no longer suppresses the ask, and no surface claims a grant isn't needed.

Why. dp, 2026-10-23, picking this ("b") over a seat editing the being's files. cbp-being asked at least six times for <ws>/hestia/plugins/_shared/hestia_governance_closure.py, which is in the editable tree. Its standing grant on <ws>/governance/** held a copy at the mirrored path, and memory_read of that copy worked. Every surface it met pointed the wrong way:

surface	before	now
gate refusal (mrh.path)	"'hestia' is not granted (granted: …) Scope request … still pending"	starts with the copy as an alternative (below), then the gate's text
relative read hestia/plugins/…	"A file DOES exist at <ws>/hestia/plugins/…. To read it: memory_read …" (unreadable)	names the original as outside your reach, then the copy as the alternative
dispatcher out-of-reach	"a real boundary … request_scope"	the copy as the alternative first, then the boundary text
request_scope	filed	still filed, unchanged. When a copy exists, the result adds copy_in_reach and meanwhile

One wording on every surface (copy_alternative):

A copy at the same path exists under a grant you already hold: X (under your grant G). If reading it is what you need, memory_read that copy now; it is a separate file and may differ from 'P'. If you need 'P' itself (its current contents, or to change or run it), request_scope it and say which.

The match (same_path_in_reach) accepts one shape only: a recursive grant on a directory G whose parent also holds the asked path. The copy is the asked path with G's name inserted.

• It never matches on just any shared tail.
• Paths are canonical, and a copy must stay inside its canonical root, so a symlink out of a grant doesn't count.
• Exact grants are skipped. Every matching root is returned, sorted.
• Refused writes never get a copy offered.
• No hardcoded paths. Reach doesn't widen, and nothing is withheld from a decider.

Measured against the live layout with cbp-being's recursive grants:

• the closure file, hestia_single_gate.py, core/src/server/http.rs and README.md each resolve to their governance/hestia/… copy;
• web4/README.md and /etc/passwd match nothing.

Tests: test_same_path_in_reach.py, 9 tests.

• request_scope is filed both for "I need to edit the original closure table" and for a read reason. The copy's contents are deliberately stale, and the result names the copy.
• The gate refusal starts with the alternative and never says that no grant is needed.
• The relative read names the original as out of reach and doesn't offer it as readable.
• The matcher covers: mirror only, exact grants, absent copies, paths already in reach, symlink escape, and grant-order independence.

Sabotage, 7 cases:

• each of the four surfaces switched off;
• suppressing the request again;
• calling the copy proof that no grant is needed;
• loose tail matching.

Each one fails exactly its own test.

Gateway suite, after merging origin/main (#519, #520): 1789 passed, 32 skipped, 2 failed. The failures are test_activity_reports and test_body_and_gaze, which also fail on main.

NOVA exact-head review 78efe4a443 — HOLD on request_scope suppression semantics. The deterministic sibling-root matcher and read-refusal hint are useful, and the 9 tests show no lexical tail broadening/symlink escape. But an existing file at <ws>/governance/hestia/... is not necessarily the same content or authority target as <ws>/hestia/...: your own fixture deliberately writes editable\n and snapshot\n. More importantly, _do_request_scope unconditionally returns same_path_in_reach for any matching request, even if the being explicitly needs the editable original for a write/execute, or needs its current (not snapshot) bytes. That suppresses a legitimate scope request. Please keep the helpful alternate-read hint, but only suppress the request when the ask is explicitly for reading the snapshot/copy (or introduce an explicit requested intent/act distinguishing read vs write). Otherwise preserve the original scope-request path, and frame the copy as an alternative, not proof that 'no grant is needed'. Add negative tests for a request reason 'I need to edit the original' and for stale/different snapshot contents; assert the request is still filed. Since grant requests are governance decisions, the client shouldn't silently substitute a different object without confirming equivalence. Syntax CI green; re-review after fix.

@nova: re your HOLD on 78efe4a. Revised at f3fe81a.

• request_scope is no longer suppressed. It files exactly as before. When a mirrored copy exists, the result adds copy_in_reach and meanwhile, and a hestia error carries the same text.
• The copy is framed as an alternative, never as proof. All surfaces now share one sentence: the copy "is a separate file and may differ from 'P'. If you need 'P' itself (its current contents, or to change or run it), request_scope it and say which." Nothing says a grant isn't needed. The relative read used to replace the original's path with the copy's. It now names the original as outside reach, and the copy as the alternative.
• The negative tests you asked for: a request with reason "I need to edit the original closure table" is filed, and so is one with a read reason. In both, the fixture's copy is deliberately stale (different bytes) and the request still goes to hestia. A test asserts that "no grant is needed" is absent. Putting the suppression back, or calling the copy proof, each fails its own test.

Gateway suite after merging main: 1789 passed, 32 skipped. The 2 failures also fail on main.

NOVA merge pass 2026-10-23: #527 was merged (scope-status receipt fix, e20cc06). GitHub now reports this PR as not mergeable against updated main (merge conflict; #522's direct merge attempt returned HTTP 405). Please rebase/resolve against current main, preserve the existing fixes and tests, and re-run CI. Holding merge until refreshed head is verified.

[dp-web4]

@nova: merged origin/main at dc71bc0 (no rebase). The one conflict was in _do_request_scope; the resolution keeps both changes: #527's _scope_next receipt and this PR's copy_in_reach / meanwhile. test_same_path_in_reach, test_scope_next and test_hestia_dispatch: 122 passed. A merge preview with #521's head (7cfb866) passes all 226 tests across the five affected files.

NOVA re-review 2026-10-23: reviewed dc71bc0. Prior HOLD is addressed: request_scope still files; mirror is an alternative explicitly distinct from original; #527 receipt behavior preserved. Relevant tests reported 122/122 and syntax-gate green. I merged #521 first (ddf9883), because its run/grant-mode integration was independently ready. GitHub now reports #522 as non-mergeable against new main. Please merge current main into #522 again, retain both features, run affected tests, and ping for final merge.

[dp-web4]

@nova: merged origin/main (with #521) at 8ed7d17. It merged without conflicts, and GitHub now reports MERGEABLE. The five affected test files (same_path_in_reach, run_grant_mounts, scope_next, reference_f1a, hestia_dispatch) pass, 226 tests.

NOVA exact-head re-review 8ed7d17: prior HOLD cleared. request_scope remains filed and witnessed; the accessible snapshot is explicitly presented as an alternative, not content/authority equivalence. Current-main merge includes #521 and 226 relevant tests are reported passing; syntax CI green. Approved.
