Pin qualified `tractor` and require `trio>=0.34.0`

Advance the `piker_pin` lock from `b64c89f0` to the published
`8fe574c1`, retaining the evaluated Trio 0.34.0 release. Require
Trio >=0.34.0 for the updated cancellation APIs. Restore the Git
source used before local editable evaluation; no environment sync
is included.

Record the human's overlapping charts, Gateway data reset and
close/reopen qualification. Keep the full Gateway restart string
error and Tractor teardown callback assertion explicit as separate
recovery limits. Offline lock validation resolves 126 packages;
this is not a fresh-install qualification claim.

+# IB recovery qualification, 2026-11-06
+
+This records human-operated qualification of the bounded #94
+landing on `wkt/land_ib_recovery`, starting from `495c0915` plus
+the narrow history catch described below. It supplements the
+historical evidence in `ai/ib-recovery-candidate.md`.
+
+## Runtime and dependency source
+
+The evaluated environment uses Python 3.13, Trio 0.34.0 and Tractor
+`8fe574c1e447358dafd8ebf5ada3b0714c688f78`. Tractor was an editable
+local checkout during evaluation. The human subsequently published
+that exact commit as GitHub's `goodboy/tractor:piker_pin`; a read-only
+remote query confirmed the published OID before restoring Piker's
+Git source and recording the same OID in `uv.lock`.
+
+Offline lock validation resolves 126 packages successfully. No
+environment sync was performed. This validates the lock metadata;
+it does not claim a fresh installation from the published source.
+
+## Manual observations
+
+The human operated Gateway, chart windows and paper orders. The
+agent did not operate live services or the account.
+
+- Same-feed overlap, close/reopen and paper order submit/cancel
+  worked after the existing order-dialog guard was imported.
+- Different-feed overlap originally exposed a timed-out one-second
+  MNQ March 2027 gap query. PDB showed `timedout=True` and
+  `out is None`. Its uncaught `NoData` canceled sibling history and
+  quote tasks even though `pikerd` remained alive.
+- After the narrow catch, the human reported the overlap journeys
+  working, then confirmed cases 5 and 6 with Ctrl+Alt+F: overlapping
+  live feeds survived the Gateway data reset; closing all charts
+  and reopening with `pikerd` left running restored live updates.
+- Earlier Ctrl+Shift+R attempts left feeds live, but do not prove
+  that the intended Gateway data reset was triggered.
+
+These are manual observations, not automated timing or latency
+measurements. Ctrl+Alt+R was not qualified here; Piker's utility
+labels it a connection reset.
+
+## Narrow history backport
+
+Only the `NoData`/`DataUnavailable` catch around `get_hist()` in
+`maybe_fill_null_segments()` is copied from
+`0846cbd4a4197e47415689cf5e9d146ba3174c32`, authored by
+`goodboy <goodboy_foss@protonmail.com>`. The existing gap fallback
+remains in place; this does not import broader history repair.
+
+The new regression uses real null detection and checks that a
+sibling in the same nursery still runs after either provider
+exception. Both cases failed before the catch. With it, the two
+focused history files passed: 17 tests. Earlier bounded-recovery
+and Tractor qualification results remain separate evidence, not
+fresh test runs of the final dependency commit tree.
+
+## Remaining recovery limits
+
+A full Gateway restart was triggered accidentally through its
+auto-restart settings dialog. The disconnect delivered the string
+`Peer closed connection.` to `deliver_trade_events()`. The string
+branch then reached `err['reqid']`, raising `TypeError`; its `code`
+local can also retain an earlier event's value. Full Gateway restart
+recovery is outside this bounded landing.
+
+The earlier history-failure teardown also exposed a separate
+Tractor completion-callback assertion after `BrokenResourceError`.
+The history catch does not establish that this callback race is
+fixed. Broader history recovery and these disconnect paths remain
+downstream work.

+
+## Prompt
+
+The human requested a commit plan, then a fast-forward landing of
+the #94 branch and PR updates. They agreed the temporary local
+Tractor source must be replaced, published piker_pin themselves,
+and reported "pushed it". They also supplied the manual recovery
+results and full Gateway restart failure diagnostics.
+
+## Response summary
+
+Restore the Git Tractor source after local qualification and lock
+its published piker_pin at 8fe574c1e447358dafd8ebf5ada3b0714c688f78.
+Retain the evaluated Trio 0.34.0 lock and require Trio >=0.34.0.
+Record the human's overlap, data-reset and reopen observations,
+the narrow history extraction, and full-restart recovery limits.
+Offline uv lock validation passed without an environment sync.
+
+## Files changed
+
+- `pyproject.toml`: Trio minimum; restore existing Tractor Git source.
+- `uv.lock`: published Tractor OID and evaluated Trio 0.34.0.
+- `ai/ib-recovery-qualification-20261106.md`: scoped evidence.
+
+## Human edits
+
+The human selected the bounded landing scope, performed live tests,
+identified the more aggressive reset distinction, and published
+the tested Tractor ref. The agent applied the metadata edits and
+wrote the qualification record from those observations. No human
+acceptance or task-state transitions are inferred by this record.
