The maintainer should not access SchemaStore directly. These components communicate through the messaging layer, and introducing a direct reference breaks that architectural boundary and tightly couples their lifecycles.

I think we need to keep tracking the table until its candidate checkpoint instead of removing it after the first NeedAddedTables.
For example:
- the bootstrap snapshot is at ts=10 and table
tdoes not exist; tis created at ts=20;tis dropped at ts=30;- bootstrap reports the old dispatcher as
Stoppedwith checkpoint=30.
At ts=20 this code adds t to addedTables and removes it from candidates, so the drop at ts=30 never invalidates it. Later buildWorkingTaskMap skips the stopped dispatcher, but processTableSpans creates a new absent span from ts=20. The scheduler may then recreate a dispatcher for a table that has already been dropped.
Could we replay both add and drop state through each candidate's upper timestamp, including normal and database-level drops, and only keep the tables that still exist there? A create-then-drop regression case would also help cover this.
…est pods (#5245) ## What Raise the `golang` container resources of the three `pingcap/ticdc` light integration-test pod templates to 24Gi / 8 cpu: - `pipelines/pingcap/ticdc/latest/pull_cdc_storage_integration_light/pod-test.yaml` (16Gi / 6 cpu -> 24Gi / 8 cpu) - `pipelines/pingcap/ticdc/latest/pull_cdc_mysql_integration_light/pod-test.yaml` (16Gi / 4 cpu -> 24Gi / 8 cpu) - `pipelines/pingcap/ticdc/latest/pull_cdc_kafka_integration_light/pod-test.yaml` (16Gi / 6 cpu -> 24Gi / 8 cpu) This matches the memory of the heavy templates and gives the light jobs the same headroom, while staying well inside the node capacity. ## Why These three jobs have been failing on the target staging Jenkins (`do.pingcap.net/jenkins-staging`) since 2026-09-07/08 with a staging-only mechanism: PD's embedded etcd stalls for several seconds (`kv gets too slow`, `keep alive lease too slow`, `clock offset` with a multi-second jet lag on a 50ms refresh interval), the PD leader lease expires, PD steps down, and the CDC servers all exit with `ErrCaptureSuicide`, so the test CLI fails. The same commit passes on the from-Jenkins (GKE). The stalled paths are the PD/TiKV data directories under `/tmp`, which the pods only get 6 (mysql light: 4) cpu to serve while PD + TiDB + TiFlash + 3x TiKV + 3x CDC + the downstream services all run inside the same cgroup. Evidence: four replays of the same JOB_SPEC (`pingcap/ticdc#6207 55270ded`) on staging, with the pod template inlined into the replay script so that only the resource limits differ: | replay | pod resources | result | PD stall | | --- | --- | --- | --- | | `#23` | 16Gi / 6 cpu | FAILURE | yes | | `#24` | 24Gi / 8 cpu | SUCCESS (9/16 groups) | no | | `#25` | 24Gi / 8 cpu | SUCCESS (16/16 groups) | no | | `#26` | 16Gi / 6 cpu | FAILURE | yes | The concurrent load was comparable in the passing and the failing windows (16-17 concurrent jobs on the production Jenkins instance, which shares the same TKE cluster), so the earlier failures are not explained by a quiet window. This unblocks the migration presubmits `#5219`, `#5218` and `#5234`, which are currently red only because of this environment failure. ## Validation - `yq` parses all three templates. - `.ci/verify-k8s-pod-yaml.sh` passes (`kubectl` client and server dry-run). - `.ci/verify-storage-class-policy.sh` passes. - The replay builds above used exactly these limits (`requests=limits` = 8 cpu / 24Gi) and ran the full 16-group matrix green.

What problem does this PR solve?
Issue Number: close #6202 ref #5083
What is changed and how it works?
Recover tables created after the bootstrap checkpoint from DDL history, preserving surviving dispatchers and split eligibility while repairing missing span coverage. This avoids duplicate scheduling during maintainer failover.
