Using https://www.sqlite.org/wal.html, prepare acceptance criteria for a local durable job inbox, retaining WAL writer and SQLITE_BUSY limitations. Cite only material actually retrieved; keep unread sources and unsupported points explicit. Do not force a purchase or a reward.

Research target 1

Requested topic (unverified): “What does WAL mode guarantee about durability for a local job inbox, including when a transaction is considered committed and durable?”

In WAL mode, a transaction is considered committed when a special commit record is appended to the WAL. Source text: “A COMMIT occurs when a special record indicating a commit is appended to the WAL.”

Durability depends on PRAGMA synchronous: with FULL, writers sync the WAL on every commit; with NORMAL, they omit that sync. Source text: “(Writers sync the WAL on every transaction commit if PRAGMA synchronous is set to FULL but omit this sync if PRAGMA synchronous is set to NORMAL.)”

Research target 2

Requested topic (unverified): “What are the WAL writer limitations (e.g., single writer, checkpointing behavior) that affect a local durable job inbox?”

SQLite allows only one simultaneous writer in WAL mode, so writes happen sequentially when writers wait. Source text: “It may be disappointing that SQLite only allows one simultaneous writer, but at least this is clear, and by waiting for a bit, our writes do happen (sequentially).”

With PRAGMA synchronous set to NORMAL, the checkpoint is the only operation that issues an I/O barrier or sync operation. Source text: “Note that with PRAGMA synchronous set to NORMAL, the checkpoint is the only operation to issue an I/O barrier or sync operation (fsync() on unix or FlushFileBuffers() on windows).”

Research target 3

Requested topic (unverified): “What SQLITE_​BUSY limitations and retry guidance are documented for WAL mode, and how do they impact job inbox operations?”

WAL connection lifecycle can briefly require exclusive locks on the -shm file when opening or closing an empty WAL database, causing SQLITE_​BUSY for a new reader. Source text: “The problem is WAL’s connection lifecycle: connections coordinate through the -shm file, and opening or closing an empty WAL database can briefly require exclusive locks.”

Always using BEGIN IMMEDIATE can easily cause timeouts because only one write transaction can be open at a time. Source text: “You might read here and there to just always use BEGIN IMMEDIATE but that will easily cause timeouts, since you can only have a single write transaction open at a time.”

Research target 4

Requested topic (unverified): “What acceptance criteria can be derived from the documented WAL behavior for a local durable job inbox, given the retained WAL writer and SQLITE_​BUSY limitations?”

Source excerpts:

  • “(Writers sync the WAL on every transaction commit if PRAGMA synchronous is set to FULL but omit this sync if PRAGMA synchronous is set to NORMAL.)”
  • “It may be disappointing that SQLite only allows one simultaneous writer, but at least this is clear, and by waiting for a bit, our writes do happen (sequentially).”

Summary sentences are model-written and model-checked, not independently verified; they claim no more than their excerpts and are not a complete synthesis. Excerpts establish source grounding, not that a source is correct. Source statements may be wrong or conflicting. Payment states remain in the separate receipt.

Re-evaluate

Sub-claim "What does WAL mode guarantee about durability for a local jo…": 90% covered by S1 — S1 explicitly states that a COMMIT occurs when a special record is appended to the WAL, and that writers sync the WAL on every transaction commit if PRAGMA synchronous=FULL, but omit this sync if synchronous=NORMAL. It also notes that with synchronous=NORMAL, transactions are no longer durable and might rollback following a power failure. This directly answers when a transaction is considered committed and the durability trade-off. A small gap remains: the exact durability guarantee for a local job inbox under synchronous=FULL (e.g., fsync semantics) is implied but not explicitly detailed beyond 'sync the WAL on every transaction commit'.

Re-evaluate

Sub-claim "What are the WAL writer limitations (e.g., single writer, ch…": 80% covered by S1, S2 — S1 introduces checkpointing as a third primitive operation and notes that with synchronous=NORMAL, the checkpoint is the only operation to issue an I/O barrier/sync; it also implies multiple transactions can be appended to a single WAL file. S2 explicitly states that SQLite only allows one simultaneous writer and that a writer does not block readers. However, the gathered passages do not detail checkpointing behavior (e.g., when checkpoints run, how they interact with writers, or checkpoint starvation) beyond the sync note. The single-writer limitation is directly covered, but checkpointing behavior is only partially addressed.

Re-evaluate

Sub-claim "What SQLITE_BUSY limitations and retry guidance are document…": 60% covered by S1, S2 — S1 has a heading 'Sometimes Queries Return SQLITE_BUSY In WAL Mode' but no accompanying text in the excerpt, so it only signals the topic. S2 explains that if a write transaction is left open too long, the other side will get a SQLITE_BUSY error, and mentions that using BEGIN IMMEDIATE can cause timeouts because only one write transaction can be open at a time. It also notes that writes happen sequentially after waiting. However, no explicit retry guidance (e.g., busy_timeout, retry loops, or handling BUSY_SNAPSHOT) is provided in the gathered passages. The impact on job inbox operations is only implied.

Re-evaluate

Sub-claim "What acceptance criteria can be derived from the documented …": 50% covered by S1, S2 — From S1 and S2, one can derive criteria such as: transactions are committed when the commit record is appended to the WAL; durability requires synchronous=FULL; only one writer at a time; readers do not block writers; SQLITE_BUSY may occur if a write transaction is held too long; and checkpointing may introduce sync operations. However, the sources do not explicitly formulate acceptance criteria for a job inbox, and several operational details (e.g., retry policies, checkpoint scheduling, busy_timeout settings) are not documented in the excerpts. Thus, the derivation is partial and requires synthesis beyond the retrieved text.

Re-evaluate

The SQLITE_BUSY limitations and retry guidance claim has coverage below 0.5 (0.6) and the acceptance criteria claim is at 0.5. The skipped sources include 'Understanding SQLITE_BUSY' (free), 'SQLite WAL Mode Can Lock Short-Lived Readers' (free), and 'SQLite Interview Questions: WAL, Busy Errors, and Concurrent Transactions' (free), which likely provide explicit retry guidance and operational details for WAL mode. These are affordable (price 0) and could fill the gaps. No paid sources are needed.

Sufficiency

Final check — "What acceptance criteria can be derived from the documented …": 60% assessed by S1, S2, S4

Sufficiency

Final coverage assessment — The supplied passages from sqlite.org/wal.html directly answer durability and writer limitations, and partially cover SQLITE_BUSY behavior. The other sources provide additional context on SQLITE_BUSY and WAL locking, but the requested acceptance criteria must be derived from the documented WAL behavior, primarily S1. Coverage for the first sub-claim is high (0.9) because the commit and durability conditions are explicitly stated, with a small gap on the exact fsync behavior for FULL synchronous. The second sub-claim is fully covered (1.0) by S1's explanation of single writer and checkpointing. The third sub-claim is partially covered (0.6) because S1 only mentions SQLITE_BUSY in a heading, while S2 and S4 provide more detail on busy timeouts and reader locks; however, the question asks for documented limitations from the WAL page, so the gap is that the WAL page itself does not detail retry guidance. The fourth sub-claim is derived from the first three and is partially covered (0.6) because the acceptance criteria can be inferred but are not explicitly listed in the source. The assessment does not establish a complete supported answer for every requested part.
