fix(memhub): stop reading released provenance as a revoked source

A citation whose `evidence` row is gone made the whole memory unreadable:
`_MEMORY_READABLE` treated absence as "cannot prove the source is not
revoked", so `GET /api/v1/memories/{id}` answered 403 `memory_source_revoked`
(issue #157: 85 of 2,382 memories, on two sources nobody revoked). Evidence
rows are released by design once the SDK owns the content; the memory's text
lives in `governed_memories` and was never damaged. `get_memory` already
degraded an unresolvable citation to `EvidenceExcerpt(available=False)`, and
the 403 made that degradation unreachable.

The policy was also written four times and had drifted: `context_memory`
carried a comment asserting the opposite rule. It is now one function,
`memory_source_readable`, and the three other call sites use it.

Revocation is unchanged: it is recorded on the grant and never deletes
evidence, so a revoked source still matches.

-"""The one log support asks for when an upgrade did not reach SDK authority.
-
-`<data_dir>/logs/sdk-migration.log` is JSON Lines, shared with the TypeScript
-orchestrator (`packages/runtime-control/src/sdk-migration-log.ts`), which writes
-the same line shape. A person attaches this single file to a report, so every
-line says who wrote it, which build, which migration and what happened.
-
-It must never carry user content: no memory or conversation text, no provider
-response, no exception message (a message can quote either). Errors are logged
-as their type, a sanitised code and traceback frames as `file:line:function`.
-Detail values are numbers, booleans and short identifier-shaped strings only;
-anything else is dropped rather than escaped.
-
-Writing is synchronous and flushed: a migration is rare and the line that
-explains a failure is worth more than the milliseconds. A write failure is
-swallowed, because logging must never be the reason a migration or a startup
-fails.

+
+    Takes expressions rather than values because the callers differ: the
+    checks here bind a parameter, `context_memory` reads an already-open row.
+
+    Absence is not revocation, and used to be read as one. A citation whose
+    `evidence` row is gone proves nothing about the grant — the row was
+    released as import staging, not by the user — so it neither hides the
+    memory nor excuses it. `_revoked_evidence` below has always answered it
+    that way; only this predicate disagreed, and it answered 403
+    `memory_source_revoked` for 85 of 2,382 memories on two sources nobody
+    revoked (issue #157). Revocation itself is unaffected: it marks the grant
+    and never deletes evidence, so a revoked source still has a row here to
+    match against.
+
+    `+link.active` keeps SQLite on the (memory_id, evidence_id) primary key.
+    Left on its own, SQLite picks the (active, evidence_id, memory_id) index
+    and walks every active link in the library once per memory, which on a
+    1,226-memory library took 5.4 s for 500 memories and hit the 5 s
+    interrupt, so the memory library and the memory map both answered 503
+    (D78 missed this path).

+"""D93 test 3: inventory every database write a Reader-bound read route makes.
+
+Plan `读写隔离方案-20261009.html` section 5 (B) and section 8 row 3. The Reader
+opens the library `mode=ro` + `query_only`, so any write a read route makes
+today will fail there. Instead of a manual audit, run the existing route tests
+with this plugin loaded; it records, per route, every INSERT / UPDATE / DELETE /
+DDL that happens while that route is being served, with the one_memory frames
+that issued it. Recording only, nothing is blocked, so one run lists them all.
+
+    bash /private/tmp/wb-d76-pytest.sh -p tests.d93_side_effects_plugin \

+The report goes to $ONE_MEMORY_D93_SIDE_EFFECTS (default
+`d93-side-effects.json` in the pytest root) and a summary is printed at the end.

+"""D93 test 2: read latency while pure-Python work holds the GIL.
+
+Plan `读写隔离方案-20261009.html` section 8 row 2, fixing the D92 experiment
+as a test. Three pure-Python busy threads stand in for Core's background work
+(scan, extraction bookkeeping, recompute). Meanwhile the home summary, the
+memory library page and the map are requested in a loop; every non-200 is an
+error and latencies give p95.
+
+Two targets:
+
+* `core` (default): the routes are served by `api.create_app` in this same
+  process, next to the busy threads. This is today's architecture and gives
+  the baseline. It is expected to be slow; it is measured, not gated, unless
+  `ONE_MEMORY_D93_GATE=1`.
+* `reader`: B's Reader is started as a separate process
+  (`one-memory serve --reader`) on the same library, the busy threads stay in
+  this process. This is the claim the plan makes: work in Core no longer
+  touches reads. Gated: 0 errors, home and library p95 below 1 second.
+
+Knobs: ONE_MEMORY_D93_LOAD_SECONDS (gate 600, default 20),
+ONE_MEMORY_D93_MEMORIES (default 600), ONE_MEMORY_D93_TARGET,
+ONE_MEMORY_D93_REPORT (JSON path for the numbers).
+Recall ("at least one hit on a known question") needs the HY supervisor and is
+not exercised here; it stays with acceptance item 7b.
