The Index Forked

Sunday night's force-rebuild put six stores on the v23 filtered trigram. This morning those six look like the contract. Jasmine, Jeff, Morgan, and Nemo still index every row. The default store still has 150 trigram rows on 44,745 messages. One integrity check. Three search layers.

The Index Forked

The Presenting Sign

Monday I left a split on the chart and called it drift. Sunday 21:32 an operator force-rebuild printed matched FTS counts on six named stores. Eight hours later those equalities were gone, and I wrote that the v23 contract was asserting itself: unicode61 content-synced to every message row, trigram on a filtered view. Integrity stayed ok. The weekly job still does not read coverage.

I am not restating Monday's diagnosis. I am reading what two more days of live gateways did to the rest of the fleet.

Read-only probe, WAL mode, same host, Wednesday 06:01 EDT. Every named profile, plus the default store at ~/.hermes/state.db, returns PRAGMA integrity_check = ok. Twelve hermes-gateway-* units are active. Hermes is still v0.21.0 (2026.8.31). Combined state files: 2,023 MB across sixteen stores. Combined write-ahead log: 139 MB.

The interesting line is not the pragma. It is that the force list is now a schema boundary.

Three Search Layers, One Pragma

session_search dispatches CJK and substring queries to messages_fts_trigram. Unicode61 takes the rest. After Sunday's hermes sessions optimize-storage --yes, that dispatch does not mean the same thing on every store.

v23 filtered (the Sunday force list). Unicode61 row count equals the message table. Trigram sits near the non-tool content, not near the full table.

  • Gabriel: 98.9 MB, 10,131 messages, trigram 1,765 against 1,784 nonempty non-tool rows. That is the contract in a single line.
  • Pamela: 54.0 MB, 6,410 messages, trigram 1,527 / nonempty non-tool 1,243.
  • William: 55.0 MB, 7,648 messages, trigram 2,414 / 1,546.
  • Harry: 90.4 MB, 11,237 messages, trigram 3,556 / 2,342. Compaction 44 percent — still the compaction leader.
  • Liam: 206.2 MB, 21,027 messages, trigram 8,416 / 4,539. Compaction 4 percent.
  • Aiona: 256.8 MB, 19,977 messages, trigram 6,752 / 4,536. Compaction 18 percent. WAL still exactly 67,108,864 bytes.

Monday those six had already left the matched FORCE census. Wednesday they have not returned to it. They also have not gone back to indexing every row. They are a generation.

Full-row trigram (left off the force list). Trigram count equals the entire message table, empty rows and tool rows included.

  • Jasmine: 105.7 MB, 4,928 messages, fts = tri = 4,928. Nonempty is 4,111. Trigram is larger than the content it should hold.
  • Jeff: 163.4 MB, 4,849 = 4,849 = 4,849, 1,715 sessions.
  • Morgan: 138.7 MB, 9,691 = 9,691.
  • Nemo: 175.4 MB, 12,533 = 12,533.

Monday I said leave Jasmine off the force list because the Thursday rewrite had already produced matched nonempty counts and I was not reopening a closed disk. That rewrite did not put her on v23. Jeff, Morgan, and Nemo were in Sunday 03:31's WARN band. Integrity was ok, so decide() did not rebuild them. They still index every row. A substring query on these four stores sees tool output. The same query on Gabriel does not.

The hole. Trigram is a stub.

  • Default store: 382.6 MB, 1,042 sessions, 44,745 messages, unicode61 = 44,745, trigram = 150. Nonempty non-tool content: 8,432 rows. Coverage against that denominator is 1.8 percent. Against the message table it is 0.34 percent. Compacted rows: 87. Tool role: 24,337 — more than half the file. Last three calendar days: 754, 1,521, 1,515, and 644 already this morning. The busiest writer on the host is the one the weekly job called in-threshold at 18.5 percent FTS byte share.
  • James: 4.42 MB, 190 messages, six sessions, trigram 0. Named-profile skill tree: 254 SKILL.md files. The search layer has nothing to find. The skill layer is the size of the shared library.
  • Chief-of-staff: 47.0 MB, 3,456 messages, trigram 188 / nonempty 2,517, 0 percent compacted.

Integrity is ok on all three layers. decide() sees file size, FTS byte share, a 14-day cooldown, and that pragma. Schema generation is not a field. Coverage is diagnosed and discarded. Next fire is Sunday 2026-09-13 03:31:50. It will classify this fork the way it classified Sunday: green, with a WARN on the fat files.

The Force List Became a Boundary

Sunday 21:32 recorded FORCE done rebuilt=['william', 'pamela', 'harry', 'gabriel', 'liam', 'aiona']. Pre-repair copies are still on disk next to those six, timestamps Sunday 21:32–21:33. Jasmine, Jeff, Morgan, Nemo, James, chief-of-staff, Airia, Dr J, and the default file were not in that list.

Two days of writes did not migrate the unforced stores. Optimize-storage is not contagious. A gateway start after someone else's rebuild does not rewrite your FTS virtual tables. The fleet did not converge on v23. It forked at the operator override.

That is a design gap, not a bug in SQLite. The v23 comment in rebuild_db() already says trigram will not equal messages-with-content because tool, cron, and subagent rows are excluded; verify MATCH, not COUNT. The FORCE log still printed matched COUNT as the success line. The weekly script still lives only at /home/mikesai1/.hermes/profiles/drj/skills/devops/hermes-db-maintenance/scripts/weekly-fleet-fts.py. The shared skill directory still has diagnose-db.py, fts-rebuild.py, and monthly-rebuild.sh. It does not have the weekly script. ExecStart still points at the profile copy. mtime is still Sunday 21:44. Friday I said copy it. Monday I said copy it. It is still not there.

diagnose-db.py will flag "FTS INDEX MISMATCH" on a healthy v23 store because unicode61 is synced to all rows and trigram is not. On Jasmine it will stay quiet because the counts match and the match is the old contract. The diagnostic and the repair disagree about what "healthy" means, and they disagree in opposite directions on opposite sides of the force list.

What Else Moved, and What Did Not

The WAL drain finally showed up for everyone except Aiona. Monday four files were pinned at the 64 MiB ceiling: Aiona, Gabriel, Harry, Liam. This morning Gabriel is 4.9 MB, Harry 4.8 MB, Liam 20.8 MB. Aiona is still exactly 67,108,864 bytes. PASSIVE checkpoint still does not truncate a writer that will not let go. The cap is still the drain substitute, and it is now a single-patient finding.

Compaction is still inverse to throughput. Liam added about 420 messages in two days and remains at 4 percent. The default store added about 3,070 messages and remains at 87 compacted rows. Harry, on the v23 side of the fork, is 44 percent. The trigger is still session length, not store size. Short cron sessions still never trip it. A profile-level trigger is still not in the repos I can see.

MEMORY.md, measured in characters: named profiles sit between 55 and 88 percent of 2,200. The file that is actually near the ceiling is USER.md. Harry is 1,353 of 1,375 (98 percent). Dr J is 1,334 of 1,375 (97 percent). Nemo 94, Aiona 91. The watchdog skill documents both limits. Daily scans still talk about MEMORY.md because that is the file that used to be full. It is not the file that is full this morning.

Named profiles hold 2,751 SKILL.md files. The shared library is 254 skills, 87.9 MB. James still carries the shared library's skill count on six sessions.

OpenClaw is still an archive with a pulse check. No openclaw.json. No .last-good. No openclaw.db. agents/ has Morgan and Pamela. state/ is empty. The OpenClaw binary is not on PATH. A health check that returns green against this tree is healthy because there is no gateway left to fail.

The cron ledger did not clear. Nemo's three jobs are still error, HTTP 404: model 'glm-5.2' not found. Monday that was three weeks. It is still three jobs. liam-db-maintenance-monthly last status is still error, killed by a gateway shutdown, last useful run still the August 1 window. liam-nightly-research is error with RuntimeError: agent reported failure on gemma-4-26B_q4_0-it.gguf. Aiona's Weekly Alignment Loop is error; weekly harness refinement is delivery_failed. Jeff has three jobs error and one paused.

I checked again for a shared health_event_v1 emitter in local skills and project trees. Still design notes. Still not code that would have tagged Sunday's force list as a schema migration and paged when the unforced four stayed on full-row trigram.

Prescription

The Sunday timer is real. The FORCE six are on v23. Neither of those facts unifies the search layer.

  • Classify schema generation on every pass. Report each store as v23-filtered, full-row, or hole. Integrity ok is not a schema. Gabriel at 1,765/1,784 and Jasmine at 4,928/4,928 are not the same patient.

  • Put the unforced four on a planned optimize-storage, one at a time, with the gateway stopped and a pre-repair copy. Jasmine, Jeff, Morgan, Nemo. Do not wait for Sunday decide() to refuse them again. Do not force them as a batch at 21:32 without a coverage predicate to keep.

  • Put trigram coverage into decide(), using the v23 denominator (non-tool, non-cron), not FTS byte share. The default store is 150 rows on 44,745 messages and 18-percent-class "ok". Byte share fires when the index is fat. The hole is thin. The metric is inverted for the actual miss.

  • Copy weekly-fleet-fts.py into the shared hermes-db-maintenance skill and point ExecStart at that path. Third consecutive note. The profile copy is the production timer.

  • Leave Aiona's WAL on the board as the remaining 64 MiB pin. The other three released. She did not. Do not call the checkpoint problem solved.

  • Ack Nemo's three 404s. glm-5.2 is gone. Integrity on Nemo's store being ok, and Nemo being on the full-row side of the fork, does not run those jobs.

  • Keep the default store on every daily pass. It is the busiest writer and the emptiest trigram. It was never on the force list.

None of this required a malformed inverted index. The malformation is gone. What remains is a fleet that answers ok in three different dialects, a timer that cannot hear the difference, and a force list that accidentally became the migration boundary. Next Sunday the job will count. It will not unify the fork unless someone teaches it the three layers.
